SS Evaporator Coil for Tunnel Freezer

SS Evaporator Coil for Tunnel Freezer

When the tunnel freezer is running, the low-temperature and low-pressure refrigerant liquid enters the evaporator coil, absorbs the heat of the surrounding air in the coil and evaporates into a gaseous state, thus lowering the temperature of the coil surface. The cooled air is forced to circulate through the fan, flowing through the evaporator coil surface, the heat will be transferred to the refrigerant in the coil, to realize the cooling of the air cooling. So the cycle is repeated, so that the temperature inside the tunnel is reduced to the required freezing temperature, in order to achieve the rapid freezing of food and other items of treatment!

Tubes are usually made of stainless steel, such as 304L, 316L, etc., which have good corrosion resistance, strength and rust resistance, and can adapt to the low temperature, humidity and possible chemical erosion in the freezing environment. The fins can be made of aluminum, stainless steel and other materials, of which aluminum fins have good thermal conductivity and can effectively enhance the heat exchange efficiency.

Performance Advantages

High-efficiency refrigeration: The optimized tube row design and fin structure make the evaporator coil have a large heat transfer area and good heat transfer performance, which can quickly take the heat away from the tunnel and realize the rapid freezing of food, shorten the freezing time and improve the production efficiency.

Strong stability: the evaporator coil made of stainless steel has high strength and corrosion resistance, and can operate stably in a long-term low-temperature, high humidity environment, reducing the frequency of failures, lowering the maintenance cost, and ensuring the continuous and stable work of the tunnel freezer.

Uniform cooling: through the reasonable airflow organization and coil arrangement, it can make the temperature distribution in the tunnel more uniform, avoiding the situation of local temperature being too high or too low, ensuring the consistency of the quality and taste of the frozen food.

Application areas

Food processing industry: widely used in the frozen treatment of quick-frozen vegetables, fruits, meat, seafood and other foods, can quickly reduce the temperature of the food, inhibit the growth of microorganisms and enzyme activity, prolong the shelf life of the food, and maintain the freshness and nutritional composition of the food.

Pharmaceutical industry: It is used for the frozen storage and transportation of medicines, vaccines, etc., to ensure the quality and stability of medicines in a low-temperature environment, and to meet the demand for the cold chain of pharmaceutical products.

Other fields: It can also be applied to the process of chemical and electronic industries which have the demand for low-temperature environment, such as the frozen crystallization of certain chemical raw materials and the low-temperature testing of electronic components.
