Evaporator with Fan for Apple Cold Store

Evaporator with Fan for Apple Cold Store

An evaporator with a fan for an apple cold store is a crucial component in the refrigeration system, which is mainly used to accelerate the cooling process by forcing air circulation.

Structure: It is usually composed of an evaporator coil, a fan (including a motor and fan blades), a defrosting device, a water receiving tray, and a housing. The evaporator coil is typically made of copper or aluminum tubes, inside which the refrigerant flows. The fan forces air to flow through the coil, and the defrosting device is used to prevent frost from affecting heat transfer. The water receiving tray collects the condensed water generated during defrosting, and the housing is made of anti-corrosion materials to protect internal components.

Working Principle: The liquid refrigerant in the evaporator coil absorbs heat and evaporates into a gas, absorbing the heat in the cold store. The fan forces the air in the cold store to flow over the evaporator coil, accelerating the heat exchange process between the air and the refrigerant, thereby rapidly reducing the temperature in the cold store.

Advantages

Rapid Cooling: The fan - driven forced ventilation mechanism enables the evaporator with a fan to quickly lower the temperature in the apple cold store, which is very suitable for the rapid cooling of newly harvested apples to quickly bring them to the optimal storage temperature range of 0 - 1 °C.

Good Temperature Uniformity: By continuously circulating the air, the evaporator with a fan can make the temperature in the cold store more uniform, avoiding local overheating or overcooling, which is beneficial for the uniform preservation of apples.

Easy Defrosting: Most of these evaporators are equipped with a highly automated defrosting function, such as electric defrosting, water - flushing defrosting, or hot - gas defrosting. This reduces the need for manual intervention, improves work efficiency, and ensures the normal operation of the evaporator.

Convenient Installation and Maintenance: The evaporator with a fan is relatively easy to install and disassemble, especially suitable for large - height cold - store spaces. During maintenance, it is also relatively convenient to check and maintain components such as the fan motor and the evaporator coil.
