Countercurrent Cooling Tower Food Factory

High-temperature process equipment in food factories (such as sterilizers, steamers, pasteurization lines, frying equipment, etc.) will generate a lot of waste heat during operation. If not cooled in time, it may cause equipment overheating, reduced efficiency or even failure. The cooling tower removes the heat of the equipment through circulating cooling water to maintain the equipment at a suitable temperature (such as jacket cooling of sterilizers, shaft seal cooling of mixing equipment, etc.).

In food production, process water for washing and cooling food raw materials or semi-finished products often needs to be recycled (such as meat cooling, water recycling after beverage bottle washing). High-temperature process water can be reused after being cooled by the cooling tower, which can not only reduce fresh water consumption, but also avoid the growth of microorganisms caused by excessive water temperature (for example, the cooled water is circulated for fruit and vegetable washing, and the water temperature can be controlled at 20-25℃ to inhibit bacterial growth).

Food factory workshops (such as baking workshops and aseptic filling workshops) need to maintain a constant temperature (usually 18-25℃) through air conditioning, while cold storage requires a low temperature environment (below -18℃). The condensers of these refrigeration systems (such as the condensers of screw chillers) need to be cooled by cooling water. Cooling towers can efficiently cool high-temperature refrigerants (such as Freon) in the condensers, improve refrigeration efficiency and reduce energy consumption (for example, the inlet water temperature of the cold storage condenser drops from 35℃ to 28℃, and the cooling capacity can be increased by 10%-15%).

If food factories directly discharge high-temperature wastewater or dissipate heat from equipment, the ambient temperature of the workshop or factory area will increase, affecting the operating comfort of workers and product quality (for example, a high temperature environment may cause chocolate to melt and bread to ferment abnormally). Cooling towers cool high-temperature water through centralized heat dissipation, circulate it after cooling or discharge it in compliance with standards, and avoid heat accumulation in the production area.
