Abstract

651,862. Cheese. WOUD, H. Dec. 30, 1947, No. 34643. Convention date, June 8, 1945. [Class 84] In a process of manufacturing a dried cheese product the initial cheese material is converted into a molten mass by breaking up, rolling and incorporating during rolling an aqueous solution of citric acid and sodium carbonate, the amounts of which are controlled according to the acidity of the initial cheese material so as to yield in the resultant molten mass a pH between 6.5 and 7.0 and the molten mass is then heated with sufficient water and agitation to effect emulsification and thereafter dried in finely divided form. As shown, the raw cheese is fed into a screw mill 1 broken up and passed to a rolling unit 2 where during rolling the mixture of citric acid and sodium carbonate is fed from a mixer 3 by a sprayer 5. The rolled cheese mass is then mixed in the hopper 6, passed into a conveyer 9 having an internally-heated screw 11 from which it is discharged at 10 to internally steam heated drying rolls 12 and formed into a dried mm which is scraped from the last roll and reduced to powder by a rotating brush 14. The powder may be passed through a shaking sieve 15 and pressed into blocks by a press 16, wrapped and labelled by a machine 17 and removed by conveyers 18. In an example to each 100 Kg of fullcream cheese (fat content 45 per cent) is added a solution prepared from 6 litres of water, 3,000 grms. citric acid and 2,250 grms. sodium carbonate.
