Title:
METHOD AND APPARATUS FOR DIRECTLY HEATING A PROTEIN-ENRICHED MILK PRODUCT BY INTRODUCING STEAM INTO SAID MILK PRODUCT
Document Type and Number:
WIPO Patent Application WO/2021/013377
Kind Code:
A9
Abstract:
The invention relates to a method and an apparatus 1000 for directly heating DE a protein-enriched milk product P by introducing steam D into said milk product P, the direct heating DE taking the form of an infusion IFV or injection method UV. The problem addressed by the invention is that of creating a method of the type in question and an apparatus for performing the method which have the effect of significantly extending shelf life in the method process or in the apparatus, and in doing so ensuring a content of non-denatured whey proteins in the treated protein-enriched milk product greater than that obtained in the prior art. The problem is solved by process-engineering means in that • the milk product (P) which is preheated and kept at temperature is indirectly cooled (K) prior to direct heating (DE) by a recuperative cooling step from the preheating temperature (TVE) to a cool-down temperature (TK) with a temperature difference (ΔΤΚ) in a range from 5 K(elvin) to 15 K (ΔΤΚ < (5 to 15) K), • the direct heating (DE) from the cool-down temperature (TK) to the pasteurisation temperature (THE) is controlled by means of direct heating setting values which are per se known, and • in accordance with feature (d), the milk product (P) is cooled by flash cooling (K) from the pasteurisation temperature (THE) to a necessarily required output temperature (TA).
