  • the whey permeate is produced during the manufacture of whey protein concentrates from whey from cheese production.
  • the liquid that was left over Whey permeate is concentrated, dried and crystallized.
  • Whey permeate usually contains 44 to 50 g/1 a-lactose.
  • ⁇ -lactose is converted into the desired ß-lactose crystals in a crystallizer and then a secondary drying and cooling process can follow.
  • a crystallization belt conveyor is known, for example.
  • the crystallization belt conveyor is designed with an electric geared motor drive and a tensioning system for the belt guide.
  • the belt itself is constructed in an open weave manner to allow cleaning through the weave of the belt. Nevertheless, the fabric of the belt is easily colonized by microorganisms and consequently there is a risk of insufficient or even non-existent hygiene during CIP (clean in place) cleaning. Due to the hygiene requirements, especially in the food industry and pharmaceutical industry, the possible use of such a crystallizer is limited.
  • the large amount of space required due to the linear conveying section of the crystallization belt conveyor is disadvantageous .

Due to the homogeneous application of the preliminary product to be crystallized and taken up without mixing, a defined crystallization and a defined residence time is made possible by a circular movement of the upper surface of the receiving unit. Due to the fact that the preliminary product to be crystallized is only If, in particular, a smooth surface is applied to the rotatable receiving unit, it is easy to clean and all the requirements for CIP cleaning, for example in the food and pharmaceutical industries, can be met without great effort.
