PerMix Vacuum Mixer and Dryer - Vacuum Mixing and Vacuum Mixers

The considerably superior heat transfer characteristics of PerMix PTP-D series Vacuum Mixer Dryer are mainly attributable to the fact that external heat applied through the contact surfaces of the mixing vessel and mixing element, supplemented by frictional heat generated during the mixing process.

When operating at the usual speed, this accounts for 30 to 35 percent of the total heat applied. Heat transfer is not inhibited by agglomerates or layers of material adhering to the internal components of the tank. This is largely due to the comminuting units and the high-speed, edge-sweeping paddle agitators, which ensure rapid circulation of the materials at the contact faces.

7. Easy to clean and sterilize.
8. Long service life through the use of corrosion resistant reactor materials (Stainless Steels, Hastelloy, Titanium, Nickel Alloys).

Horizontal Vacuum Mixers & Dryers are the most popular vacuum mixers & dryers offered on the market as they are available in the most configurations and types.  With size ranges from 1 liter to 30,000 liters and higher, combined with agitation types that include:

• Paddle & Plow Mixers
• Ribbon Mixers
• Fluidized Zone Mixers
• Hi-Speed Granulators

These types of vacuum mixers & dryers allow the user to select a configuration that allows them to mix any type of product and achieve desired results needed whether they need a no/low shear effect or a very quick resizing of products leading them to choose a medium to high-shear type, and anything in between.

With the additions of choppers, these units are very versatile and allow users to meet the needs of today yet adapt to the demands of tomorrow easily and quickly.

Vertical Vacuum Mixers & Dryers are rapidly becoming more popular than the horizontal versions.  Although the operating theory is the same, the advantages of going vertical bring with it several advantages which include:

• Larger surface area contact in regards to heat transfer versus horizontal mixers
• Less residue left in the mixer due to its vertical, center bottom discharge, which allows for an easy discharge of product with minimal to low/no residue left behind.
• Requires less product space/footprint, which lowers them amount of space needed for the production area.  Ideal for small facilities with big production demands.When cleaning between batches, cleaning is quicker and, if using CIP, water is easily drained completely which lowers the amount of waiting between batches is needed.A larger flexibility of batch sizes is allowed as the vertical mixers allow for a lesser amount to be used for a minimal batch size.

• With size ranges from 1 liter to 15,000 liters or more…our Vertical Vacuum Dryers allows users to select a configuration that still meet the needs of today while adapting to the demands of tomorrow quickly.

  Types of Vertical Vacuum Mixers offered include:

• Vertical Paddle Mixers
• Vertical Ribbon Mixers
• Conical Type Mixers (Nauta Style)

Tumble Vacuum Mixers & Dryers gained their popularity as they possess all the same characteristics of vacuum mixing & drying yet have fewer moving parts and are very easy to use as well as maintain.  The tumbling action allows for an aggressive yet gentle mixing.  Our tumble mixers may also include intensifier bars which add to mixing efficiency if mixing products/ingredients of various densities.

Our Vacuum Tumble Mixers & Dryers are available in size ranges from 1 liter to 10,000 liters and include:

• V-Blenders
• Double Cone Mixers

Validations Made Easy With PerMix 4-in-1 Hybrid Vacuum Mixers & Dryers

Change is hard in the manufacturing industry as the need to update and validate new process technology is a pain staking task that takes a large amount of time as well as a large financial commitment. It is not as simple as just taking a mixer or other piece of equipment and changing it out. Everything that is currently in place and running has been proven and validated and properly assessing the changes wanted, as well as validating them is hard to do. That is until now.

PerMix has changed the way R&D teams validate their manufacturing process. We have create a hybrid mixer that allows you to choose from a standard mixer, a heated & cooled mixer, or a mixer that has the ability to operate under pressure or vacuum. In addition to have the ability to choose operation mode, we also give you the ability to choose between 4 different mixing types of agitation. Choose from a ribbon mixer, plow mixer, paddle mixer, or a single shaft fluidized zone mixer. No longer do you need to purchase 4 mixers because you have 4 types of agitation.

This streamlines the validation process and means that processing line changes can be easily tested and validated. Imagine, just loading the mixer according to the current process and then programming in the current, already validated parameters. Turn the mixer on and watch the mixer mix according to the existing protocol. Then once the PLC/HMI panel has recorded all the steps, imagine switching agitation types, maybe one that would allow you to certify as a LEAN manufacturing, and recording all the data points in the new process mixer. Now you can compare side by side the characteristics and the way each batch reacts to the current protocols as well as the future, making validation of new procedures easy.

In addition if you want to validate the need for pressure or vacuum mixing/drying compared to your current process, just run the current process under your current validated procedure and the PLC/HMI will record the data. Then after, simply program the new process that needs validating with pressure or vacuum, and compare the two. There is nothing like a real-time comparison of the two processes, all with only spending the money for one mixer.
