PerMix Vacuum Paddle Mixers & Mixers/Dryers

PerMix Vacuum Paddle Mixers/Dryers Lead The Industry In Innovation, Performance, & Quality

PerMix PTPD series Vacuum Mixer Dryer is a turbulent mixing reactor-dryer. It is used as a high-speed paddle dryer, chemical reactor, or, if both processes are combined, as a dryer-reactor. They are used with particular success in agglomeration-free rapid drying, heterogeneous reactions with systems of different substances, extraction, sterilization and in general for vacuum, positive-pressure, thermal energy and comminuting aids.

PTPD Vacuum Mixing Dryers are widely used in the chemical, metallurgic and pharmaceutical industries among others. Standard sizes range from 3 liters up to 10,000 liters and pressure from 10 mbar up to 50 bar.

This particular PTPD 350 unit, was specially designed to the specific requirements of the customer, for optimizing the drying process of a Fe powders with Solvent traces, has special packing seals on main shaft, is medium vacuum rated ( up to 200 Mbar absolute ), built-in self cleaning heated filter, liquids condenser with collection tank, special semi hemispherical discharge pneumatic operated valve and many more “goodies”.

Vertical vs Horizontal Ribbon Mixers

PerMix Engineering Team Presents: Vertical vs Horizontal Ribbon Mixers, Which Mixer To Choose

Both of the mixers are generally used to mix dry powders and most often end users are confused as to which mixer would be suitable for them?

Ribbon blender is a horizontal blender that is used to mix the dry powders gently. Ribbon blender consists of inner and outer ribbons, where the outer ribbon continuously lifts the material and pass it to inner ribbons where they are traversed axially.

Cone Screw blender is a vertical mixer that is used to mix the dry powders even more gently as compared to the ribbon mixer. Here the materials are mixed with the help of the self-rotation screw which lifts the material from the bottom of the cone to the top and then the materials fall down by gravity.

Here are some of the factors one should consider before choosing between Ribbon Blender and Vertical Cone Screw Blender:

Less Footprint: Ribbon blender occupies more footprint area as compared to the Vertical Cone Screw blender but headspace required for the same is higher.

Initial & Energy Costs: The capital cost of Vertical Cone Screw Blender is higher as compared to that of the Ribbon blender. But, the power cost required to run the ribbon blender is greater than required for the Vertical Cone Screw blender.

Discharge: Ideally speaking Vertical Cone Screw blender can give 100% of the discharge as compared to some of the 10% residual left in the Ribbon blender.

Contamination: Ribbon blender has a higher chance of contamination due to the presence of packing gland in the product zone. So, if contamination is affecting the product adversely and product quality is of great importance than one can shift to the Vertical Cone Screw blender.

Operation: If one needs to operate with the batches only occupying 20-30% of mixer volume then one can opt for Vertical Cone Screw blender. Cause unlike Ribbon blender, they don’t have requirement of minimum volume.

Gentle mixing: For the friable material, the Vertical Screw Cone blender offers gentler mixing as compared to the Ribbon blender.

Cleaning: While mixing reactive materials in batches, cleaning becomes essential. Vertical Cone Screw Mixer provides easier and complete clean up as opposed to Ribbon blender where there are chances of product leftover.

PerMix Inline Mixers & Ice Cream

How to prepare Ice-Cream with the help of Inline Mixers?

Generally Ice cream contains ingredients such as milk solids, sucrose, milk fats, syrups, stabilizers, emulsifiers, and water. Although stabilizers and emulsifiers are less in proportion they play a major role in the formation of ice cream. Stabilizers are used to prevent the growth of the ice crystals during storage, to provide the required mouth feel, etc. Emulsifiers are used to ensure that fat in ice cream is dispersed uniformly.

The stabilizers generally used in the ice cream are guar, cellulose gum, locust bean, and xanthan. Other stabilizers such as acacia, agar, and pectin are also used but less frequently. Emulsifiers used in the process include lactic acid, mono di-glycerides, propylene glycol esters, and blends of these.

Some of the hurdles faced during the mixing of the stabilizers and emulsifiers are long processing times required for complete dispersion, the addition of powders must be at a uniform rate to reduce agglomerates, Cleaning cycles are required frequently which leads to downtime and increase in cost, orthodox systems are not capable to produce sufficient shear to break agglomerates down.

PerMix offers Inline Mixers to address this challenge. The ingredients are rapidly introduced into the mixer and are dispersed throughout. The agglomerate formation is taken care of as stabilizers & emulsifiers are broken down. Due to the high speed of the rotor, materials are sucked in and they experience an intense shear in the rotor-stator assembly. After this, the product is discharged and again new materials are drawn in thus continuing the entire process.

A few of the benefits of the inline mixer are that it mixes rapidly, the mix produced is free of agglomeration, and premixing of the ingredients is not required. There are several more advantages, for more information contact us
