Abstract
Cheese is made continuously by flowing milk through a spiral flow path of a reactor containing an immobilized enzyme such as rennet which coagulates the milk. The spiral flow path is formed by a spirally wound microporous sheet containing the immobilized enzyme. Adjacent surfaces of the sheet are spaced apart with a spacer which can be a plurality of microporous ribs or a sheet in open net form.
Claims20
A continuous process for making cheese comprising:
- continuously flowing a substrate containing coagulatable constituents through a spiral flow path defined by a spirally wound sheet, said sheet containing within it an immobilized enzyme that causes the substrate to coagulate;
- coagulating the substrate and converting the resultant coagulate into cheese;
- said flow path being between adjacent surfaces of said spirally wound sheet containing said immobilized enzyme, said sheet being microporous and having micro-pores that interconnect adjacent flow paths formed by said spirally wound sheet, said adjacent surfaces being spaced apart by a spacer that is spirally wound with said microporous sheet, and said spacer being selected from a group consisting of:
- (a) a plurality of microporous ribs on said spirally wound sheet disposed longitudinally to said flow path, and (b) a further sheet having an open net form.
