Tetra Pak® Cheese Vat OST CH6 Horizontal vat for curd making Working principle • Even curd size distribution The milk (and in-line added starter) is fed into the vat through the bottom (or optional top) inlet and gently stirred by the combined stirring and cutting tools. • Low fat and fines losses • Very strong and reliable • Controlled heating • Advanced process control Application The Tetra Pak ® Cheese Vat OST CH6 is a horizontal vat for the curd production of cheddar/mozzarella cheese types. The vat has all required functions for a controlled and predictable process: filling of cheese milk, ingredient mixing, milk coagulation, cutting of coagulum, blending, indirect heating, emptying and CIP (Cleaning in Place). The Tetra Pak Cheese Vat OST CH6 is designed to satisfy the cleaning requirements after each batch especially for cheddar, mozzarella and similar cheese types. Using warm water in a dimple jacket to heat the product allows the operator to control the heating speed and temperature difference. In the recipe the maximum temperature difference between heating medium and product can be set, so the optimal heating rate will be achieved. After rennet addition, the milk rests to create a firm coagulum to be cut by the sharp knives of the cutting tool. The speed of the tools is controlled between 2 and 10 rpm. Once the curd is cut to the required grain size the rotation of the tools is reversed. By rotating the tools the blunt sides of the knives stir the curd and whey mixture to avoid sedimentation. The curd/whey mixture can be indirectly heated by circulating hot water through the dimple jacket. The vat is emptied through the outlet at the bottom. The curd making process is controlled from the control panel placed adjacent to the manway on top of the vat. The vat can be cleaned in place by rotating spray nozzles and a connection to the shaft seal
