Glycol Ice Water Cooling Milk Chiller

Cool about 3.5 tons of milk per hour (inhomogeneity) from 37 degrees to 3 degrees.Milk  cooled from 37 degrees to 25 degrees by 20 degrees well water for pre-cooling, then cooled down to 3 degrees by chilled water from chiller,

1. pre cooling capacity calculation
C (4.2) * M (3500) * T (37-25)/t (3600) * S (1.3) =P 1(63.7KW)
The well water flow needed: 63.7 x 0.86 / (37-25) * 1.3 = 5.9m3/h.
There must be no less than 5.9m3/h, less than 20 degrees well water to do pre-cooling to ensure the first step to pre-cool milk.

2, second cooling capacity calculation:
C (4.2) * M (3500) * T (25-3), t (3600) * S (1.3) =P 2(117KW)

3. The cooling capacity of the 2nd milk cooling system is 117kw/h, using AYD-70WS water-cooled milk chiller unit, under the evaporatiing temperature is -5 degrees, the propylene glycol temperature is 0 degrees and the condensing temperature is +38degrees, the cooling capacity is 140kw/h.

4, the milk chiller unit designed for 2 independent systems;

5, pre-cooling hot water for the cows to drink and heat recovery of spplying water, known pre cooling recovery of hot water is 5.9m3/h, pre cooling heat recovery:
4.2 x 3500 x (37-25 / 3600=49KW
49 x 0.86 / 5.9=7 +20 DEG =27 degrees
According to this calculation, the pre cooling heat recovery is 49KW, the recovery of hot water is about 5.9m3/h, the water temperature is about 27 degrees celsius.

6, the pre cooling water as a supplementary water (about 27 degrees Celsius), and then through the heat recovery unit
Hot water can be recovered about 45 degrees Celsius for boiler and cleaning use.
According to unit waste heat recovery 30% calculation, 117 * 0.3=35KW.
35 x 0.86 / (45-27) =1.67m3/h/H, there will be  about 1.67m3/h and 45 degrees hot water for boiler cleaning and use.
 

1. Glyocl chiller for milk cooling adopt the Hanbell brand semi-hermetic screw compressor, and operate credibility, high efficiency, easy to maintain, exact volume control, a wide range of application. The system adopts the latest asymmetric rotor profile. Build-in pressure drop lubricant to system with low vibrations, sound emissionshigh sealing performance.

2.Glycol chiller for milk cooling 's human machine interface configures a full touch screen, which enables automatic control and accurate monitoring. The advantages of unit: water-proof,dust-proof, corrosion resistant, long life. Step or stepless capacity control, the unit ensure that it bring into the most energy-saving effective in any load conditions.

3.Glycol chiller for milk cooling due to use heat copper tube and high efficiency compressor with high effective thermal expansion current-saving device, the unit will operate in stability, longer and effectively.

4.Glycol chiller for milk cooling adopts a reliable safety protection device: to prevent compressor starting frequently, over-current protection, overheat of motor protection, prevent freezing, sight glass in liquid, oil heating protection, phase protection, HV/LV protection, discharge high-temperature protection, safety value, soluble clock, water shut-off protection, and so on.
