Technological cooling lines and milk storage

Lines for small and large agricultural farms

Milk cooling and storage lines

These are used to store milk that has already been cooled – after milking, at a temperature of +4°C. The tank is equipped with cooling sheathing to maintain the storage temperature. The tank can store milk from two different milkings without any negative impact on the quality of the stored milk.

The bottom of the tank is equipped with cooling sheathing. All parts that come in contact with milk are either made from stainless steel of from food grade rubber. To access the upper lid the tank is equipped with a service ladder with a protection basket and platform.

The tank is equipped with an automatic sanitation system used to dispense sanitation solution from barrels, and with a flow-through heater that heats the sanitation solution while maintaining sanitation temperatures.

Devices for milk pasteurization

Milk pasteurisation is done in 250-litre batches. The milk is heated in the vessel through double sheathing. Water is the heat source. It flows through the double sheathing where heating elements are installed. A pump is used to circulate the water; the circulation is not pressurised. After the pasteurisation temperature is reached and kept for the pre-set time, the milk is cooled down and with ice water, which also flows through the double sheathing. The source of the ice water is an ice water maker connected to the tank. The entire pasteurisation process is controlled by a simple programmable device. The progress is recorded. This device is delivered assembled, but the ice water maker is separate.

Water heaters and storage vessels

Water heaters and storage vessels made from stainless steel are used to store and accumulate warm drinking or heating/service water used in residential or industrial distribution systems. The basic series offer the following volumes: 300, 500, 750 and 1,000 litres. The operational pressure in accumulation vessels reaches 10 bar (1 MPa) and the operational temperature is 95°C. Vessels are equipped with standard necks. Additional equipment depends on individual orders and the planned type of use.

Accumulation vessel may be fitted with a water heater. The water or medium may be heated by means of plate or heat exchangers, or possibly with electric heating elements. Delivered with a control system. The surface of the vessel is chemically treated by staining and passivation for stainless surfaces, which provides long service life. Proper seal of accumulation vessels is guaranteed for at least five years.

Cooling tanks

Enclosed cooling tanks are used to cool milk during primary agricultural production – after milking, at a temperature of +5°C until it is shipped for further processing. The equipment is designed to cool down two milkings per day, or four milkings per two days.

The cooling tank complies with the requirements of the European standard ISO 5708. Quick and gentle milk cooling using ice water preserving the highest quality milk; automatic cooling process with monitoring feature; process control unit located on the front of the cooling tank; electrical installation in connection with the cooling system is done through a blind opening either in the right or left wall of the tank; the tank is equipped with an air vent with DN 100 diameter, which allows for more powerful milk vacuum transportation system.
