Cooling-crystallizing plants are designed for instant cooling in a vacuum and subsequent crystallization of condensed whey that leaves evaporator and is intended for subsequent drying in the spray drying plant.

Cooling-crystallizing plant consists of two independently operating units:

  • Vacuum cooling plant.
  • Crystallizing station.


Cooling of whey is one of the major processes affecting the crystallization of lactose therein. The sizes and amount of crystals of lactose in whey concentrate can be controlled by several technological methods: the degree of supersaturation of aqueous solution of lactose, cooling rate, mechanical agitation, adding seeding agent that promotes the formation of lactose crystallization grains.

Managing the process of crystallization is carried out through touch-screen monitor by a set algorithm in compliance with the required cooling mode and the temperature gradient.

The automation system is based on programmable logic controller.

The quantity and volume of tanks depends on the amount of processed whey and capacity of the equipment involved in the process.

Specialists of the engineering group PJSC "Kalinovskiy machine building plant" are ready to make the required calculations and the selection of technological equipment required for the processing of whey available.
