Description

Defrosting control system for large particle ice machine

Technical Field

The utility model belongs to the field of ice machine processing and production, and particularly relates to a defrosting control system for a large particle ice machine.

Background

When the evaporation temperature of the refrigeration system is lower than 0 ℃, frost layers are inevitably generated on the surface of the evaporator. The frost layer not only increases heat transfer resistance, but also increases air flow resistance in a forced circulation evaporator (e.g., a cold air blower), which affects heat exchange efficiency. Therefore, no matter what cooling method is adopted by the refrigerator, measures should be taken to remove the frost layer. The defrosting method can be manual defrosting, hot air defrosting, water defrosting, hot air-water defrosting and the like. Although the manual frost sweeping is simple to operate and does not influence the temperature of the warehouse, the labor intensity is high, and the frost sweeping is not thorough.

For the particle ice machine, the evaporator is generally composed of a stainless steel plate and an S-shaped copper pipe welded on one surface of the stainless steel plate, and the other surface is provided with a plate with a specification cell for preparing particle ice.
