Product Description

Bottom Mounted Magnetic Mixer and Tank Mixer Agitator and Low Shear Mixer for Biotechnology and Fermentation

BRIEF INTRODUCTION:

Processing of liquid products often incorporates air and unwanted gases into the product. These gases normally cause problems such as oxidation, discoloration, inconsistency, bad smell and filling difficulties. The PerMix PDA series Vacuum Deaerator, or Degasser, is a totally compact sanitary device designed for the continuous automatic removal of air or other occluded gases from any type of liquid or paste, by means of vacuum.PerMix PDA Vacuum Deaerators can handle numerous processes including (but not limited to) the manufacturing of food products, cosmetics and chemicals, which requires to avoid air oxidation to ensure a correct preservation or application. End products can be sauces, fruit pulp, cosmetic creams, syrups, PVC dispersions, lubricants, car polish, shower gels, paraffin and penicillin emulsions, ice creams, adhesives, etc.

HOW IT WORKS:

The PerMix PDA series Vacuum Deaerating Machine starts to work by creating a very high vacuum in the chamber up to -0.95barG, and then the loading of product follows. In most cases, product can be sucked esaily into the chamber by the vacuum; for product of high viscosity, an extra pump is necessary to aid the loading.

The deaeration begins with the formation of a fine layer of product, which is distributed firstly on a high speed centrifugal disc with dismountable sieves surrounding it. Depending on the product character and/or processing requirements, the sieve number can be from 0 to 3, with the sieve hole size also to be decided, typically from 1-3mm.

The creation of fine layer under vacuum makes the air bubbles in the product burst and the product is then deaerated. Besides, during its passing through the sieve holes, the product particle is subject to shearing, folding, particle size reduction, etc, which results in even better separation of air from product particles.

Away from the centrifugal disc, the product is then sprinkled in radial direction toward the chamber wall. It then stops there, flows by gravity, and forms another thin layer all over the wall below the centrifugal disc, continuing to be deaerated by the vacuum, and finally arrives at the discharge port, and discharged by means of a positive displacement pump (screw pump, diaphragm pump or the other type).
