Application of HEAD-POWER AIR CONDITIONING thermostat dehumidifier in food processing industry
In the food processing industry, in order to shorten the production cycle and achieve uninterrupted production throughout the year, it is necessary to create a production condition of low temperature, low humidity and high wind speed, that is, artificially simulate the natural environment outside the winter. Food drying is related to the required temperature, humidity, wind speed, wind pressure and food type, curing method, packaging method, and production storage cycle. In general, foods with low water content, dry curing, cooking, vacuum packaging and other conditions can be appropriately reduced temperature and humidity requirements, but must be tested in small samples, and sufficient empirical data can be confirmed as design indicators.
First, the equipment configuration: In order to achieve the special environment required for food drying, industrial temperature and dehumidification units should be selected, and a special air supply and exhaust system should be configured. According to the temperature, humidity range and special requirements of food hygiene, it is advisable to select equipment according to the principle of freezing dehumidifier and high temperature dehumidifier. It should have automatic operation and sectional adjustment function, and take into account the air volume matching in different seasons. It is possible to increase the water output rate and reduce energy consumption.
Second, the system principle: the air suspended in the air-dried room to the air emitted by the air, the humid air is sucked into the air dehumidifier, first encounter the low-temperature coil cooling gel condensation water, that is, freezing and dehumidification, and then through the heating coil Warm up, reduce its relative humidity and send it to the air-drying room with a certain air volume and wind speed. In this cycle, the moisture in the food is continuously discharged by the air dehumidifier, and after a few hours, the food is dried. In the process of treatment, in order to remove odor, a small amount of fresh air can be introduced, and a small amount of air is exchanged for ventilation.
Third, the system operation mode: the return air part of the cycle, part of the new air mixed treatment (tempering dehumidifier) and then sent to the drying room according to the climate characteristics of different seasons to adjust the equipment operating conditions, can maximize energy savings.
