Abstract: The present invention relates to a butter making device comprising a butter containing section containing a basic butter product to be processed further, a dosing unit for adding additives to the basic butter product, and a flow restricting and generating device disposed at the butter containing section for passing butter from the butter containing section for further processing the basic butter product to the dosing unit, wherein at least one further dosing unit and at least one further flow restricting and generating device disposed at the butter containing portion for passing basic butter containing section to the at least one further dosing unit.

Abstract: A method of making cheese is provided, comprising the following steps: supplying water, fat and powders containing whey protein and lactose-reduced dairy protein concentrates into a solid-liquid mixer, emulsifying and homogenising the content of the solid-liquid mixer, applying low-pressure or vacuum to the inner space of the mixer, wherein step (b) and/or step (c) are performed until a paste-like emulsified homogenous pre-cheese mixture is obtained, and step (b) and/or step (c) are performed at a temperature between 60° C. and 85° C.
