Whey Processing Plant

Fruit Plants

Milk contains quite high level of minerals at about 0.7-0.8% on an average much of minerals contain whey which is utilize for making energetic & valuable whey powder. Whey is a by-product of the hard , semi hard or soft cheese and rennet casein is known as sweet whey. Production process containing protein, fat, lactose sugars, and salts. Whey is processed to recover fat, protein, and sugars, creating a low-value, high BOD, whey permeate stream.

It will have wide range of applications, especially in the food industry. Condensed whey and whey powder can be used for both production of foodstuffs and animal feed.

RAJ Process has proven experience in project management of major capital projects, process knowhow and active involvement in the development of the Turnkey Plants makes RAJ Process ideal partner for whey processing plant and expertise allowing us to present the best technological solution, not only at the processing economy but also at the product quality.

Process Description

Separated whey conveyed to whey pretreatment, raw whey is pasteurized & reverse osmosis process takes place. (Nourishing of whey) The basic concentration and drying processes may sometimes be combined with demineralization processes such as ion exchange, electro dialysis or nanofiltration to improve the quality of the product.

Reverse osmosis is sometimes complimentary process used for preconcentration of whey before being evaporated in evaporators. Drying of the concentrated whey is normally carried out in spray dryers.
