Choosing a commercial vacuum tumbler<\/a> is not simply a matter of selecting the machine with the largest drum or the lowest purchase price. The vacuum system itself can affect how you process the product, how much control your operators have over the cycle, how consistently marinades are absorbed, and how easily the machine fits into your daily production routine.<\/p>\n\n\n\n

For meat processors, food manufacturers, restaurants, and other commercial operations, two common questions are: What is the difference between a continuous<\/a> and non-continuous vacuum tumbler<\/a>?<\/strong> And more specifically, should you choose a Promarks TM Series or TMC Series vacuum tumbler?<\/strong><\/p>\n\n\n\n

Promarks manufactures both systems because different processors have different requirements.<\/p>\n\n\n\n

The TM Series<\/strong> uses a continuous vacuum system designed for more advanced processing control. Its vacuum system can pull, vent, and re-establish vacuum while the drum is moving, and its control system can be programmed for multiple vacuum, mixing, and rest stages.<\/p>\n\n\n\n

The TMC Series<\/strong>, with the \u201cC\u201d standing for Classic, uses a non-continuous vacuum system. It offers a simpler operating method and a more economical machine configuration for processors who do not need automated vacuum-and-rest cycles.<\/p>\n\n\n\n

Neither system is intended for every application. The right choice depends on your product, production volume, desired processing results, operator requirements, and budget.<\/p>\n\n\n\n

This guide explains the practical differences between the Promarks TM and TMC Series so you can determine which commercial vacuum tumbler better fits your operation.<\/p>\n\n\n\n

What Is a Commercial Vacuum Tumbler?<\/h2>\n\n\n\n

A commercial vacuum tumbler is a food processing machine used to tumble, mix, condition, and marinate products under vacuum.<\/p>\n\n\n\n

The rotating drum provides controlled mechanical movement while the vacuum environment changes the way the product interacts with marinades and processing solutions. Vacuum tumbling is commonly used for meat and poultry products, marinated products, prepared foods, and other applications where improved marinade distribution and product consistency are important.<\/p>\n\n\n\n

The basic process is straightforward.<\/p>\n\n\n\n

Product and marinade are loaded into the tumbler. The drum rotates at a controlled speed while vacuum is applied. The combination of vacuum and mechanical tumbling helps the product interact with the marinade throughout the processing cycle.<\/p>\n\n\n\n

However, not all vacuum tumblers create and manage vacuum in the same way.<\/p>\n\n\n\n

That is where the difference between the TM and TMC Series becomes important.<\/p>\n\n\n\n

Promarks TM vs. TMC: The Basic Difference<\/h2>\n\n\n\n

The easiest way to understand the two systems is to look at how they manage vacuum.<\/p>\n\n\n\n

Promarks’ TM Series is available in TM-150, TM-300, TM-500, and TM-1000 models, while the TMC Series includes TMC-150, TMC-300, TMC-500, and TMC-1000 models.<\/p>\n\n\n\n

The important point is that the difference is not simply \u201cexpensive machine versus inexpensive machine.\u201d<\/p>\n\n\n\n

The machines use different vacuum-management approaches, and that difference affects how the processing cycle can be designed.<\/p>\n\n\n\n

TM Series: Continuous Vacuum Tumbler<\/h1>\n\n\n\n

The Promarks TM Series is designed for processors who want greater control over the vacuum tumbling process.<\/p>\n\n\n\n

The key feature is its continuous vacuum system<\/strong>.<\/p>\n\n\n\n

Unlike a conventional non-continuous vacuum tumbler, the TM Series can maintain, release, and re-establish vacuum during the processing cycle. The internal vacuum snorkel allows the vacuum system to work while the drum remains in motion.<\/p>\n\n\n\n

This opens up more possibilities for process programming.<\/p>\n\n\n\n

Instead of simply pulling vacuum once and tumbling for a set amount of time, an operator can create a sequence such as:<\/p>\n\n\n\n

Vacuum \u2192 Tumble \u2192 Rest \u2192 Vent \u2192 Re-vacuum \u2192 Tumble \u2192 Rest \u2192 Repeat<\/strong><\/p>\n\n\n\n

The exact cycle depends on the product and the processor’s desired results.<\/p>\n\n\n\n

How Continuous Vacuum Works<\/h2>\n\n\n\n

The TM Series uses an internal vacuum snorkel to draw vacuum from the drum.<\/p>\n\n\n\n

A vacuum sensor and control system monitor the vacuum level. Once the programmed vacuum level is reached, the system can stop the vacuum pump while continuing the processing cycle.<\/p>\n\n\n\n

If the vacuum level falls below the programmed level, the system can reactivate the vacuum pump and bring the vacuum back toward the target.<\/p>\n\n\n\n

This is particularly useful in a production environment where operators want a repeatable process rather than manually monitoring and adjusting vacuum throughout every batch.<\/p>\n\n\n\n

Promarks also specifies a PV-03 microprocessor control system for the TM Series. The system allows operators to program mixing and rest periods as well as vacuum, venting, and re-evacuation sequences.<\/p>\n\n\n\n

Why Multiple Vacuum and Rest Cycles Matter<\/h2>\n\n\n\n

One of the biggest advantages of the TM Series is the ability to program multiple stages.<\/p>\n\n\n\n

For example, a processor may want to:<\/p>\n\n\n\n

    \n
  1. Load the product and marinade.<\/li>\n\n\n\n
  2. Pull the drum down to the desired vacuum level.<\/li>\n\n\n\n
  3. Tumble for a specified period.<\/li>\n\n\n\n
  4. Release or vent the vacuum.<\/li>\n\n\n\n
  5. Allow the product to rest.<\/li>\n\n\n\n
  6. Re-establish vacuum.<\/li>\n\n\n\n
  7. Tumble again.<\/li>\n\n\n\n
  8. Repeat the sequence before unloading.<\/li>\n<\/ol>\n\n\n\n

    This type of process gives the processor considerably more control than a simple single-cycle vacuum operation.<\/p>\n\n\n\n

    Repeated vacuum and rest stages can help encourage marinade movement into the product and provide a controlled mechanical conditioning process. Actual results depend on the product, formulation, load, vacuum level, drum speed, and cycle settings, so processing parameters should be established through product trials rather than assuming one recipe will work for every application.<\/p>\n\n\n\n

    Automatic Vacuum Recovery<\/h2>\n\n\n\n

    Another useful feature of the TM Series is its ability to respond to small changes in vacuum during the cycle.<\/p>\n\n\n\n

    Promarks notes that the control system can re-engage the vacuum pump if vacuum drops below the desired level during processing.<\/p>\n\n\n\n

    This matters because maintaining a consistent processing environment can reduce the need for operators to constantly monitor the vacuum gauge.<\/p>\n\n\n\n

    For processors running repeated batches, that can make the process easier to standardize.<\/p>\n\n\n\n

    TMC Series: Classic Non-Continuous Vacuum Tumbler<\/h1>\n\n\n\n

    The Promarks TMC Series takes a simpler approach.<\/p>\n\n\n\n

    The \u201cC\u201d stands for Classic<\/strong>, reflecting the traditional non-continuous vacuum system.<\/p>\n\n\n\n

    Instead of using an internal vacuum snorkel and continuously managing vacuum during drum operation, the TMC uses an external vacuum hose.<\/p>\n\n\n\n

    The operator connects the hose to the drum’s vacuum port and starts the vacuum process. The vacuum level is monitored using the machine’s analog vacuum gauge. Once the desired vacuum level is reached, the hose is disconnected and returned to its holder before the tumbling cycle continues.<\/p>\n\n\n\n

    The machine then operates the tumbling portion of the process for the selected time.<\/p>\n\n\n\n

    This design is simpler, but it also means the machine does not provide the same automatic multi-stage vacuum\/rest functionality as the TM Series.<\/p>\n\n\n\n

    Why Choose a Non-Continuous Vacuum System?<\/h2>\n\n\n\n

    A simpler vacuum system is not automatically a disadvantage.<\/p>\n\n\n\n

    There are many processing applications where the operator does not need multiple vacuum and rest stages.<\/p>\n\n\n\n

    If your process is essentially:<\/p>\n\n\n\n

    Load \u2192 Pull Vacuum \u2192 Tumble \u2192 Finish<\/strong><\/p>\n\n\n\n

    then paying for a more sophisticated multi-stage vacuum system may not provide enough additional value to justify the additional equipment cost.<\/p>\n\n\n\n

    This is where the TMC Series can make sense.<\/p>\n\n\n\n

    It provides a straightforward commercial vacuum tumbling solution without adding controls and vacuum-management features that may not be required for a particular product.<\/p>\n\n\n\n

    The TMC Series Can Also Be Useful for Heavy Bone-In Products<\/h2>\n\n\n\n

    One important difference between the two designs is the vacuum connection.<\/p>\n\n\n\n

    The TM Series has an internal vacuum snorkel. Promarks designed the snorkel to reduce the risk of damage, but heavy bone-in products still require appropriate loading and operation practices.<\/p>\n\n\n\n

    The TMC Series does not have an internal vacuum snorkel inside the drum.<\/p>\n\n\n\n

    That can be an advantage for processors working with products where bones or other hard product components could create additional concerns around an internal vacuum component. Promarks specifically identifies this as one potential benefit of the TMC design.<\/p>\n\n\n\n

    The correct choice should therefore consider the actual product being processed, not simply the machine’s price.<\/p>\n\n\n\n

    TM vs. TMC: Vacuum Control<\/h1>\n\n\n\n

    The clearest difference between the two machines is vacuum control.<\/p>\n\n\n\n

    TM Series<\/h3>\n\n\n\n

    The TM Series continuously monitors and manages vacuum.<\/p>\n\n\n\n

    The operator can program vacuum-related stages into the process, and the machine can automatically manage the sequence.<\/p>\n\n\n\n

    TMC Series<\/h3>\n\n\n\n

    The TMC Series requires the operator to establish the vacuum manually.<\/p>\n\n\n\n

    Once the desired vacuum is reached, the vacuum hose is removed and the tumbling cycle proceeds.<\/p>\n\n\n\n

    This makes the TMC straightforward but less automated.<\/p>\n\n\n\n

    For an operation where the same product is processed repeatedly and precise, repeatable vacuum\/rest sequences are important, the TM Series offers considerably more process-control capability.<\/p>\n\n\n\n

    For a simpler operation, the TMC may be sufficient.<\/p>\n\n\n\n

    TM vs. TMC: Automation and Operator Work<\/h1>\n\n\n\n

    Another consideration is how much operator involvement your process requires.<\/p>\n\n\n\n

    With the TMC Series, the operator has more hands-on responsibility during the vacuum portion of the process.<\/p>\n\n\n\n

    The hose needs to be connected, vacuum needs to be pulled, the gauge needs to be monitored, and the hose needs to be returned to its holder before the normal mixing cycle continues.<\/p>\n\n\n\n

    The TM Series automates much more of this process.<\/p>\n\n\n\n

    Once the appropriate cycle has been programmed, the machine can manage the programmed vacuum, mixing, rest, venting, and re-vacuum stages automatically.<\/p>\n\n\n\n

    For processors running multiple batches every day, this difference can become significant.<\/p>\n\n\n\n

    The question is not simply whether automation is \u201cbetter.\u201d The real question is whether the additional automation solves a problem in your production process.<\/p>\n\n\n\n

    TM vs. TMC: Product Pickup and Marinade Absorption<\/h1>\n\n\n\n

    Product pickup is another reason processors may consider a continuous vacuum system.<\/p>\n\n\n\n

    Promarks describes the TM Series as providing greater pickup through what it calls the \u201csponge effect\u201d created by the continuous vacuum process.<\/p>\n\n\n\n

    The basic concept is that repeatedly changing the vacuum condition during processing can encourage the product to interact with the surrounding marinade in a different way than a single vacuum cycle.<\/p>\n\n\n\n

    However, processors should avoid treating machine selection as the only factor controlling pickup.<\/p>\n\n\n\n

    Actual pickup depends on many variables, including:<\/p>\n\n\n\n

      \n
    • Product type<\/li>\n\n\n\n
    • Product size and geometry<\/li>\n\n\n\n
    • Marinade formulation<\/li>\n\n\n\n
    • Starting product temperature<\/li>\n\n\n\n
    • Vacuum level<\/li>\n\n\n\n
    • Drum speed<\/li>\n\n\n\n
    • Fill level<\/li>\n\n\n\n
    • Tumbling time<\/li>\n\n\n\n
    • Vacuum\/rest sequence<\/li>\n\n\n\n
    • Product-to-marinade ratio<\/li>\n<\/ul>\n\n\n\n

      For this reason, a machine should be selected based on the production process as a whole rather than assuming that one machine will automatically produce a specific pickup percentage.<\/p>\n\n\n\n

      What Do Both Promarks Series Have in Common?<\/h1>\n\n\n\n

      Although the vacuum systems are different, the TM and TMC Series share several commercial-duty design characteristics.<\/p>\n\n\n\n

      Promarks specifies features including:<\/p>\n\n\n\n

        \n
      • 304 stainless steel construction<\/li>\n\n\n\n
      • Stainless steel frame, housing, and drum<\/li>\n\n\n\n
      • Frequency drive for drum-speed control<\/li>\n\n\n\n
      • Taller frame design for positioning a standard buggy beneath the drum<\/li>\n\n\n\n
      • Harsh-environment control cover<\/li>\n\n\n\n
      • Operator safety system<\/li>\n<\/ul>\n\n\n\n

        The current TM product information also lists variable speed, reverse discharge functionality, stainless steel construction, and Busch vacuum pumps.<\/p>\n\n\n\n

        The TMC product information lists 304 stainless steel construction, an in-place vacuum-hose sensor, analog vacuum gauge, analog mixing timer, frequency motor drive, and a Busch vacuum pump.<\/p>\n\n\n\n

        That means the comparison should not be viewed as \u201cbasic machine versus commercial machine.\u201d<\/p>\n\n\n\n

        Both are commercial processing machines.<\/p>\n\n\n\n

        The major difference is the vacuum system and control philosophy<\/strong>.<\/p>\n\n\n\n

        Which Vacuum Tumbler Is Better for Your Operation?<\/h1>\n\n\n\n

        There is no universal answer.<\/p>\n\n\n\n

        The better machine depends on what you need the tumbler to accomplish.<\/p>\n\n\n\n

        Choose the TM Series When You Need More Process Control<\/h2>\n\n\n\n

        The TM Series may be the better fit when your operation requires:<\/p>\n\n\n\n

          \n
        • Multiple vacuum and rest stages<\/li>\n\n\n\n
        • Automated vacuum cycling<\/li>\n\n\n\n
        • Repeatable programmed processing<\/li>\n\n\n\n
        • Vacuum monitoring during production<\/li>\n\n\n\n
        • Vacuum re-establishment during the cycle<\/li>\n\n\n\n
        • Greater control over the tumbling process<\/li>\n\n\n\n
        • Consistent processing across repeated batches<\/li>\n\n\n\n
        • More advanced marinade and product-conditioning processes<\/li>\n<\/ul>\n\n\n\n

          If your operation is growing and you want the ability to develop more sophisticated processing recipes, the additional control of the TM Series can be valuable.<\/p>\n\n\n\n

          Choose the TMC Series When Simplicity and Cost Matter<\/h2>\n\n\n\n

          The TMC Series may be appropriate when your operation needs:<\/p>\n\n\n\n

            \n
          • Straightforward vacuum tumbling<\/li>\n\n\n\n
          • A simple operating procedure<\/li>\n\n\n\n
          • Manual vacuum control<\/li>\n\n\n\n
          • A single primary vacuum\/tumbling cycle<\/li>\n\n\n\n
          • Lower initial equipment cost<\/li>\n\n\n\n
          • Fewer advanced controls<\/li>\n\n\n\n
          • A vacuum drum without an internal snorkel<\/li>\n<\/ul>\n\n\n\n

            For processors whose products do not require repeated vacuum\/rest stages, the TMC can provide a practical commercial solution without paying for features that may not be necessary.<\/p>\n\n\n\n

            Consider Product Type Before Choosing<\/h1>\n\n\n\n

            Your product should be one of the first things you discuss with a vacuum tumbler manufacturer.<\/p>\n\n\n\n

            A machine that works well for boneless chicken may not be the ideal configuration for heavy bone-in products. A processor producing marinated beef may have different cycle requirements from a manufacturer producing prepared foods.<\/p>\n\n\n\n

            Consider:<\/p>\n\n\n\n

            Is the product bone-in or boneless?<\/strong><\/p>\n\n\n\n

            Heavy bone-in products deserve particular consideration because of the internal snorkel used by continuous vacuum systems.<\/p>\n\n\n\n

            Does the product require multiple processing stages?<\/strong><\/p>\n\n\n\n

            If you need repeated vacuum, vent, tumble, and rest stages, the TM Series provides the controls to automate that type of process.<\/p>\n\n\n\n

            How important is marinade pickup?<\/strong><\/p>\n\n\n\n

            If improving pickup is a major production objective, the continuous vacuum system deserves closer consideration and should be evaluated through product testing.<\/p>\n\n\n\n

            How much operator involvement is acceptable?<\/strong><\/p>\n\n\n\n

            If you want the operator to manually establish vacuum before each tumbling cycle, the TMC may fit your workflow. If you want the machine to manage a programmed sequence, the TM offers more automation.<\/p>\n\n\n\n

            Don’t Choose a Vacuum Tumbler Based on Capacity Alone<\/h1>\n\n\n\n

            Capacity is important, but it should not be the only specification you compare.<\/p>\n\n\n\n

            A larger drum does not automatically mean better production.<\/p>\n\n\n\n

            The actual batch size should match your product, fill level, recipe, available labor, production schedule, and desired tumbling performance.<\/p>\n\n\n\n

            An oversized machine running inefficiently may not provide the results or economics expected.<\/p>\n\n\n\n

            At the same time, buying a machine that is too small can create production bottlenecks and force additional batches throughout the day.<\/p>\n\n\n\n

            When comparing the TM and TMC models, look at the complete production requirement rather than simply selecting the largest available capacity.<\/p>\n\n\n\n

            Promarks currently offers both TM and TMC machines in multiple commercial sizes, allowing processors to discuss the appropriate model based on their application.<\/p>\n\n\n\n

            Maintenance and Long-Term Operating Considerations<\/h1>\n\n\n\n

            The purchase price is only one part of the equipment decision.<\/p>\n\n\n\n

            A commercial vacuum tumbler will become part of the production process, so ease of operation, cleaning, maintenance, controls, vacuum components, and operator training should all be considered.<\/p>\n\n\n\n

            The TMC’s simpler vacuum system can be attractive to operations that prefer straightforward equipment.<\/p>\n\n\n\n

            The TM’s additional vacuum controls and programming provide greater flexibility but also introduce a more sophisticated control system.<\/p>\n\n\n\n

            That does not mean one system is universally easier to maintain.<\/p>\n\n\n\n

            Instead, the question should be:<\/p>\n\n\n\n

            Which level of equipment complexity matches our production requirements?<\/strong><\/p>\n\n\n\n

            A processor that never uses multi-stage vacuum cycles may not benefit from paying for that capability.<\/p>\n\n\n\n

            A processor that relies on repeatable automated vacuum\/rest recipes may find the additional control extremely useful.<\/p>\n\n\n\n

            TM Series vs. TMC Series: A Practical Decision Guide<\/h1>\n\n\n\n

            If you are still unsure which machine is appropriate, start with these questions.<\/p>\n\n\n\n

            Do you need multiple vacuum\/rest cycles?<\/h3>\n\n\n\n

            If yes, the TM Series is the natural system to investigate because its continuous vacuum design supports programmed vacuum, venting, mixing, and rest sequences.<\/p>\n\n\n\n

            Do you only need one straightforward vacuum cycle?<\/h3>\n\n\n\n

            If yes, the TMC Series may be sufficient.<\/p>\n\n\n\n

            Do you want automatic vacuum monitoring?<\/h3>\n\n\n\n

            The TM Series is designed for continuous vacuum monitoring and automatic vacuum management.<\/p>\n\n\n\n

            Do you want a simpler manual process?<\/h3>\n\n\n\n

            The TMC Series provides a simpler vacuum setup using an external hose and analog gauge.<\/p>\n\n\n\n

            Are you processing heavy bone-in products?<\/h3>\n\n\n\n

            Evaluate the TMC Series carefully because it does not use an internal vacuum snorkel. If considering the TM Series, discuss loading practices and product characteristics with Promarks.<\/p>\n\n\n\n

            Is initial equipment cost a major factor?<\/h3>\n\n\n\n

            The TMC Series is Promarks’ more cost-conscious vacuum tumbler line.<\/p>\n\n\n\n

            Are repeatability and automated recipes important?<\/h3>\n\n\n\n

            The TM Series offers significantly more programmable process control.<\/p>\n\n\n\n

            Frequently Asked Questions About TM and TMC Vacuum Tumblers<\/h1>\n\n\n\n

            What is the difference between TM and TMC vacuum tumblers?<\/h2>\n\n\n\n

            The main difference is the vacuum system. Promarks TM Series machines use a continuous vacuum system with an internal snorkel and programmable vacuum processing. TMC Series machines use a non-continuous vacuum system with an external hose and simpler manual vacuum operation.<\/p>\n\n\n\n

            What does the C mean in TMC?<\/h2>\n\n\n\n

            The \u201cC\u201d stands for Classic<\/strong>. The TMC Series uses a traditional non-continuous vacuum system.<\/p>\n\n\n\n

            Can the TM Series perform multiple vacuum and rest cycles?<\/h2>\n\n\n\n

            Yes. The TM Series control system is designed to allow programmed mixing, rest, venting, and re-vacuum stages.<\/p>\n\n\n\n

            Can the TMC Series perform multi-stage vacuum\/rest cycles automatically?<\/h2>\n\n\n\n

            No. The TMC is designed as a non-continuous system and does not provide the same automatic multi-stage vacuum\/rest functionality as the TM Series.<\/p>\n\n\n\n

            Does the TM Series monitor vacuum automatically?<\/h2>\n\n\n\n

            Yes. The continuous vacuum system monitors the vacuum condition and can re-engage the vacuum pump when the vacuum level falls below the programmed level.<\/p>\n\n\n\n

            Does the TMC Series have an internal vacuum snorkel?<\/h2>\n\n\n\n

            No. The TMC Series uses an external vacuum hose rather than an internal snorkel.<\/p>\n\n\n\n

            Which is more economical, TM or TMC?<\/h2>\n\n\n\n

            The TMC Series is the more cost-conscious option because of its simpler vacuum and control system.<\/p>\n\n\n\n

            Is the TM Series only for meat?<\/h2>\n\n\n\n

            No. Vacuum tumbling can be used across a range of food-processing applications, but the correct machine, cycle, and processing parameters depend on the specific product and desired result.<\/p>\n\n\n\n

            Which Promarks vacuum tumbler should I buy?<\/h2>\n\n\n\n

            There is no single machine that is right for every processor. Consider product type, batch size, production volume, desired marinade pickup, vacuum\/rest requirements, operator involvement, and budget before selecting between the TM and TMC Series.<\/p>\n\n\n\n

            Final Thoughts: TM or TMC?<\/h1>\n\n\n\n

            The choice between a Promarks TM and TMC vacuum tumbler comes down to how much control you need over the vacuum tumbling process<\/strong>.<\/p>\n\n\n\n

            The TMC Series<\/strong> is designed around simplicity. It uses a non-continuous vacuum system, an external vacuum hose, straightforward controls, and a more economical configuration. For operations that need conventional vacuum tumbling without automated multi-stage processing, this can be a practical solution.<\/p>\n\n\n\n

            The TM Series<\/strong> is designed for processors who need more control. Its continuous vacuum system, internal snorkel, programmable controls, and ability to automatically manage vacuum, venting, mixing, and rest stages make it better suited to applications where process flexibility and repeatability are important.<\/p>\n\n\n\n

            Both approaches have a place in commercial food processing.<\/p>\n\n\n\n

            The important step is to match the machine to the product and production process rather than choosing based solely on purchase price or machine size.<\/p>\n\n\n\n

            If you are comparing the TM and TMC Series for a new production line, replacing an existing tumbler, or expanding your processing capacity, talk with the Promarks team about your product, batch size, desired processing cycle, and production requirements.<\/p>\n\n\n\n

            Contact Promarks to discuss your application and find the commercial vacuum tumbler configuration that fits your operation.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"

            Choosing a commercial vacuum tumbler is not simply a matter of selecting the machine with the largest drum or the lowest purchase price. The vacuum system itself can affect how you process the product, how much control your operators have over the cycle, how consistently marinades are absorbed, and how easily the machine fits into […]<\/p>\n","protected":false},"author":1,"featured_media":846,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15],"tags":[185,184,70],"class_list":["post-330","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-processing-equipment","tag-continuous-vacuum-tumblers","tag-non-continuous-vacuum-tumblers","tag-vacuum-tumbler"],"yoast_head":"\nChoosing the Right Vacuum Tumbler: TM Series vs. TMC Series - PromarksVac Blog<\/title>\n<meta name=\"description\" content=\"Choosing the Right Vacuum Tumbler: TM Series vs. TMC Series - Processing Equipment Choosing a commercial vacuum tumbler is not simply a matter of selecting the machine with the largest drum or the lowest purchase price.
