Drain Cooler for Food Factory

In the food production process, the temperature of the drained water or process liquid is often relatively high. The drain cooler cools the liquid to meet the requirements of subsequent treatment or discharge, preventing high - temperature liquid from affecting the environment or equipment.

Some drain coolers are also equipped with heat - recovery devices. They can recover the heat in the drained liquid and use it for pre - heating the incoming water or other process fluids, improving the energy efficiency of the entire production process and achieving energy - saving and emission - reduction goals.

By cooling the drained liquid, the drain cooler helps to reduce thermal pollution to the environment. It also helps to meet environmental protection requirements and avoid negative impacts on the surrounding ecological environment.

Working principle

Heat exchange between fluids: The drain cooler usually adopts the principle of indirect heat exchange. The hot drained liquid and the cooling medium (such as water or air) flow through the heat - exchange surface of the cooler. Due to the temperature difference between the two fluids, heat is transferred from the high - temperature drained liquid to the low - temperature cooling medium, thereby reducing the temperature of the drained liquid.

Enhancement of heat - transfer efficiency: In order to improve the heat - transfer efficiency, the internal structure of the drain cooler is usually designed with some heat - transfer enhancement measures. For example, the heat - exchange surface may be made into a corrugated or fin - type structure to increase the heat - exchange area and the turbulence degree of the fluid, so that the heat transfer between the two fluids is more intense.
