Introduction: Finished grains are one of the important nutrients in people's daily diet, which is of great significance for maintaining good health. Maintaining the right humidity during the processing and storage of cereals is key to ensuring the quality and freshness of the finished cereals. In this paper, the moisturizing technology and humidity control method of the constant temperature storage of coarse grain products will provide reference for coarse grain processing enterprises and farmers.
1.Moisturizing technology:
1) Water sealing: Finished grains are easy to absorb moisture during storage, so corresponding measures need to be taken in the constant temperature warehouse to achieve water sealing. The accumulated finished grains can be covered with moisture-proof plastic film, and sealing facilities can be installed at the doors, windows and ventilation holes of the warehouse to prevent the instruation of moisture.
2) Moisture-resistant materials: choose materials with good air permeability but not easy to be damp for the decoration and structure of the warehouse, such as hemp rope, bamboo products, etc. These materials can play a role in hygroscopic absorption and moisture balance, so that the finished grain product can maintain the right humidity during storage.
3) Moisture-proof treatment of floors and walls: Moisture-proof treatment of floors and walls, such as painting moisture-proof paint, installing underground moisture-proof layers, etc., can effectively prevent the moisture of the ground and walls from penetrating into the warehouse and maintain the stability of humidity in the warehouse.
2.Humidity control method:
1) Ventilation system: A ventilation system is set up in the constant temperature warehouse of finished grains to regulate the air circulation in the warehouse and reduce the accumulation of humidity in the warehouse. By controlling the ventilation volume and ventilation time, the humidity rise and fall can be effectively controlled. An automatic control system can be used to automatically adjust according to the humidity in the warehouse.
2) Humidity sensor: Install a humidity sensor to monitor the humidity in the warehouse in real time, and feed the data back to the automatic control system. This makes it possible to adjust the ventilation volume, refrigeration equipment, etc. in real time to keep the humidity within a reasonable range.
3) Moisturizer: According to the specific situation of the warehouse, the appropriate humidifier can be selected for humidity control. The humidifier increases the humidity in the warehouse through evaporation, ultrasonic atomization, etc., and keeps the humidity stable.
Summary: Maintaining the right humidity during the processing and storage of finished grains is the key to ensuring their quality and freshness. The ingress of moisture can be reduced by employing moisturizing technologies such as moisture sealing, moisture-resistant materials, and moisture-resistant treatments for floors and walls. At the same time, humidity control methods such as ventilation systems, humidity sensors and humidifiers are used to stabilize and control the humidity in the warehouse. The application of these moisturizing technologies and humidity control methods will help to maintain the appropriate humidity during the storage of finished grains, improve product quality and freshness, and meet people's demand for healthy food.
