Curd Clot Heat Exchanger

2 Process Line Description

Mechanized and automated line with clot flow processing

designed to produce bold curd, low-fat and "Peasant."

Clot production is based on acid coagulation of milk proteins by fermentation

its pure cultures of lactic acid bacteria.

The Y9OPT2.5 line includes:

The Ya1OSV5 tank for acceptance, souring of milk and receiving a clot,

consisting of housing, stirrer, drive, washing device with thermal

a jacket for supplying heat-cooling agent thereto;

Pump single-screw unit P8ONB for supply of curd clot from tanks to

clot heat treatment apparatus;

Clot heat treatment apparatus in flow;

Boiler unit for heating water and supplying it to the jacket of the thermal apparatus

clot processing. The plant provides water heating and automotive support

coolant temperature;

Curd clot dehydrator for release from serum clot representing

is a conical drum tapering to the outlet, which is driven into rotation with

by means of electric motor connected to reduction gear box. When the drum rotates, the speed

the dewatering is controlled by changing the inclination angle by means of a lifting mechanism;

rotating from a separate drive installed on the service site;

Curd cooler consisting of two auger type displacement drums,

located in the housing of two conjugated cylinders with one common hopper;

mounted on the bed;

System of pipelines, valves and pumps for feed and transportation of raw materials and

products to line aggregates.

The process of curd production on the line begins with filling the reservoirs with pasteurized, homogenized and cooled milk to the fermentation temperature. In them, fermentation and fermentation occur, as well as mixing milk with starter and clot in tanks. After mixing, the finished clot is fed from the tanks by a screw pump to the clot heat treatment apparatus, where it is heated, held and cooled. The curd clot, after heat treatment in the heat exchanger, enters a rotary dewatering device, where the whey is separated from the clot through a filter cloth (lavsan), collected into an intermediate tank, and by means of a self-suction pump is withdrawn for redundancy in the tank.

Further, cottage cheese coming out of dehydrator is fed through tray into bin of two-cylinder cooler. Here, the curd is captured by the conical part of the rotary drum and fed into the space between the cylinders and the extrusion drum. Cottage cheese moves along cylinder by screw of cylindrical part of drum, is pushed into hole in detachable cover of drum and is supplied for packing.

Curd cooled to a temperature of 812 ° C is packed on M6AP2T packing machines into briquettes of parchment of 0.25 kg. Packaged cottage cheese is directed to the storage chamber for post-cooling.

The control and control system used in the line allows you to monitor the progress of the technological process, the main parameters of milk, clot, finished product, hot and ice water, as well as steam and compressed air.
