Milk fast cooling system for the electric milk pasteurizer
Normal temperature fresh milk comes from the electric milk pasteurizer, reaches 4 ℃ instantly after being cooled by the ice water milk quick cooling equipment, and then enters the milk warehouse for storage or directly enters the fresh milk transport vehicle to the dairy factory.
Characteristics and advantages of ice water system:
1. The cooling medium of milk is pure ice water, which will not cause any harm to milk.
2. The ice water evaporator adopts the rain curtain plate heat exchanger with international leading technology, with high heat exchange efficiency, energy saving and environmental protection, long service life and few operating equipment.
3. The whole system adopts central integrated control and field control, and the system operates reliably.
4. CIP cleaning adopts zone cleaning method. Pneumatic valve and tube plate are changed for joint operation. There is no dead angle left in cleaning. The operation is safe and reliable to avoid unnecessary loss caused by mixing cleaning water and milk. At the same time, the milk cooling pipeline and the milking machine are cleaned simultaneously to save cleaning liquid and cleaning time. CIP cleaning is controlled by program.
5. The warm water tank (50 ℃) adopts the partition type, one area is the heating area of heat recovery cycle (the water temperature does not reach 50 ℃), the other area is the constant temperature water area of 50 ℃. When supplying water to the outside, the warm water area will not make up water frequently, so that the water temperature is low, so as to ensure the constant water temperature. The cleaning temperature can be effectively guaranteed, and the cleaning effect is better.
6. The hot water tank (80 ℃) uses electric heating conduction oil to indirectly heat the hot water, effectively preventing the electric heating pipe from scaling and frequent burning out. At the same time, like the warm water tank, it also adopts the zone type, one zone heating, one zone constant temperature water zone. The cleaning temperature can be effectively guaranteed, and the cleaning effect is better.
7. The refrigeration system adopts screw chiller with heat recovery, automatic energy regulation, energy saving and environmental protection. Fully automatic temperature control. The V-shaped air-cooled condenser is adopted, and the system pressure controls the start and stop of the fan. Less equipment, reliable control and convenient maintenance.
8. The milk warehouse adopts the temperature digital display, milk level simulation display and control, cleaning water level control, sampling valve, rainproof breathing cap, mixing, all-round cleaning nozzle and other devices, and the whole high-pressure and high-density polyurethane foam, so that the milk warehouse can achieve visual, intelligent and efficient operation.
9. The pneumatic valve and the tube plate are used for the operation of the milk inlet and outlet pipeline of the milk bin, which is safe and reliable.
