Abstract
The production of whey products such as whey butter and whey cheese is effected by first concentrating raw whey to a total solids content of 40 to 80% by weight, thereafter adding non-heat sensitive raw materials and adjusting the pH thereof to value of between 5.8 and 6.4. The concentrate is thereafter heated in order to precipitate the whey proteins therefrom and kept at a predetermined elevated temperature for a period of time in order to insure the quality of the product. Heat sensitive additives are thereafter added and finally the concentrate is homogenized or comminuted by other means. The concentrate is cooled to a temperature below thirty degrees and thereafter stored until a suitable consistency is obtained.
Claims5
Apparatus for the production of ready-to-eat whey products such as whey butter, whey cheese and the like, comprising a sequential processing line having, in combination,
- an evaporator for receiving raw whey obtained from cow milk, goat milk or the like and for concentrating said whey to total solids of 40-80% by weight,
- first storage means for receiving the concentrate from said evaporator,
- means communicating with said first storage means for supplying non-heat-sensitive additives to said concentrate, and for adjusting the pH thereof,
- heat exchanger means connected to the outlet of said first storage means for heating said concentrate at a temperature between 90.degree. and 100.degree. C. for a time sufficient to precipitate the whey proteins,
- second storage means for receiving the concentrate from said heat exchanger,
- means communicating with said second storage means for adding heat-sensitive additives thereto,
- homogenizer means connected to the outlet of said second storage means for homogenizing said concentrate,
- cooling means connected to the outlet of said homogenizer for reducing said concentrate to a temperature below 30.degree. C. and
- third storage means for holding said cooled concentrate until a desired consistency is obtained.
