What Should I Do If The Freezing Speed Of The Block Ice Machine Is Slow?
Leave a message
The block ice machine has a wide range of uses, and is widely used in ice factories in ports and wharfs, fresh-keeping, cooling, and long-distance transportation of aquatic products. Block ice machines are divided into direct cooling block ice machines, brine block ice machines and container block ice machines, etc. But what should I do if the block ice machine freezes slowly?
Reasons for the slow freezing speed of the block ice machine:
1: The surface of the evaporator is dirty, greasy or dusty, and the heat transfer effect is reduced.
Solution: The equipment has not been used for a long time, the water quality is unqualified, in addition to the poor heat transfer effect of the evaporator, the dust has not been cleaned for a long time, the surface of the evaporator is very thick, and the heat transfer efficiency is reduced.
2: The efficiency of the compressor is low, and the cooling capacity cannot meet the ice making load.
Solution: The compressor runs for a long time, wears seriously, the gap between the compressor increases, the sealing performance decreases, the gas transmission coefficient of the compressor decreases, and the cooling capacity decreases. When the ice production is less than the ice production load, the ice production efficiency reduce. The cooling capacity of the compressor is determined by observing the compressor suction and discharge pressure.
3: The direct cooling block ice machine has poor insulation effect or poor sealing performance, resulting in large cold loss.
Solution: Poor thermal insulation performance is caused by insufficient thickness of the insulation layer of the pipeline, uneven thickness of the evaporator plate, poor thermal insulation effect, and improper selection of the thickness of the insulation layer or the production process by the manufacturer.
4: The cooling capacity of the block ice machine refrigeration system is insufficient.
Solution: Reasons for insufficient refrigerant, insufficient refrigerant filling, large refrigerant leakage, find the leakage point, and check it again.
