Basic principle of cooling device for instant noodle production line

Release time:
Page view

       The basic principle of cooling in the instant noodle production line: fried instant noodles have a higher temperature after being fried, and when transported to the cooling machine, the temperature is generally around 80-100 ℃. When the noodles from the hot air drying machine reach the cooling machine, their temperature is still around 50-60 ℃. If these noodles are not cooled and packaged directly, it will cause the noodles and soup to be difficult to store. If the cooling does not meet the predetermined standard, it will also cause moisture absorption and mold inside the packaging. Therefore, cooling the product is necessary. Cooling methods include natural cooling and forced cooling.

  1. Natural cooling refers to the use of the characteristic that the temperature of the surface is higher than room temperature, by placing the cooled surface indoors, allowing the surrounding air to absorb its heat, and slowly cooling with the passage of time. This cooling method is not suitable for continuous production.

  2. The principle of forced cooling is the same as that of natural cooling, which utilizes the temperature difference between the cooled object and the cooling medium for refrigeration, but the specific method is different. Forced cooling is the use of a blower to enhance the flow of air, allowing the cooled object to pass through a cooling tunnel and rapidly cool and dissipate heat under the action of cold air.

  Our Dongfang Naomu instant noodle production line is equipped with strong air cooling equipment. The high-temperature fried dough is quickly cooled by strong air cooling, bringing the temperature of the dough close to room temperature for easy packaging and storage. The fan can be used to lower the temperature by blowing down and pulling up or by side entering and pulling up.

  Dongfang  Naomu  Machinery Equipment Co., Ltd. has been specializing in manufacturing noodle machines for over 40 years. For the noodle equipment sold to customers, we have established a good service system from initial consultation to plan setting, on-site visits, and later on-site installation, personnel training, etc. We are dedicated to providing comprehensive system services and professional technical support to new and old customers.
