PerMix Deaerator

PerMix Deaerators remove unwanted gases and air from finished products. Deaerators extend shelf life, improve packaging, & improves quality. PerMix manufactures Deaerators for continuous & batch deaeration, up to 30,000 liters / 7,900 gallons per hour in a single unit.

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 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) the manufacture of food products, cosmetics and chemicals amongst others, need to avoid air oxidation to ensure a correct preservation or application. End products can be mentioned, such as sauces, fruit pulp, cosmetic creams, syrups, PVC dispersions, lubricants, car polish, shower gels, paraffin and penicillin emulsions, ice creams, adhesives, etc.

The PerMix PDA series Vacuum Deaerator starts to work by forming a very high vacuum in the chamber up to -0.95barG, and then to load the product. The product can be even sucked into the chamber by the vacuum if it is with low/middle viscosity, or be transferred with a pump. 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 layer all over the wall below the centrifugal disc, and finally arrives at the discharge port, and discharged by means of a positive displacement pump (screw pump, diaphragm pump or the other type).

What Makes The Difference Between A Concentrate & A Super Concentrate In Regards To Manufacturing? When we make concentrates we make them by removing the water and ensuring they are water soluble. When we make super concentrates we not only remove the water but we also remove the air. By removing the air we change the density of the product. By changing the density, the weight per liquid ounce increases and this is key in making super concentrates. The more air that is, the more dense the pro.
