Humidity requirements for food storage warehouses:

Ganzangku

The relative humidity of the dry food warehouse should be controlled between 50% and 60%; if it is a warehouse that stores food such as rice and noodles, the relative temperature should be lower. If the relative humidity of the dry storage is too high, a dehumidification and drying device (such as a dehumidifier) should be installed; if the relative humidity is too low, the air is too dry, and humidification equipment (such as a humidifier) should be used.

Cold storage

The humidity of fruit and vegetable cold storage should be between 85%-95%; the humidity of meat, dairy products and mixed cold storage should be kept between 75%-85%. If the relative temperature is too high, the food will become slimy, promote the growth of bacteria and accelerate the deterioration of the food; if the relative humidity is too low, it will cause the food to dry out. You can cover the food with a damp cloth or splash water directly on the food.

freezer

The freezer should maintain high humidity, otherwise the dry and cold air will absorb ingredients from the food. Frozen food should be wrapped with anti-moisture or anti-evaporation materials to prevent the food from losing moisture and fat from going bad and smelly.

All food warehouses should avoid direct sunlight. Frosted glass should be used for glass windows in warehouses. When selecting artificial lighting, cold light lamps should be selected as much as possible to avoid the increase of the indoor temperature of the warehouse due to the heating of the electric lights.

In addition, the storage warehouse should maintain good ventilation. It is best to change the air in the dry storage room four times per hour. The food in the refrigerator and freezer compartments should not be stored against the wall, and should not be placed directly on the floor or stacked on the ceiling to facilitate air circulation.

Or ①Temperature requirement　　

a. Dry storage. It is best to control around 10°C, of course, 15°C-22°C is also a generally accepted temperature. 　　

b. Cold storage. The main function of cold storage is to prevent the growth of bacteria. Bacteria usually multiply the fastest between 10°C-50°, therefore, all refrigerated food must be kept in a cold room below 10°C. 　　

Because of the different types of food, there are different storage objects and cold storage rooms, and their corresponding cold storage temperatures are also different. 　　

The cold storage temperature of meat should be between 0°C-2°C; 　　

The refrigeration temperature of fruits and vegetables should be between 2°C-4°C; 　　

The refrigeration temperature of dairy products is between 0°C-2°C; 　　

The best refrigeration temperature for fish should be around 0°C.

Refrigerators that store a variety of foods can only use a compromise solution to adjust the temperature between 2°C and 4°C on average.

c. Freezers. The temperature of the freezer must generally be kept between -18°C and -24°C.　　

②Humidity requirements 　　 The humidity of the food raw material warehouse will also affect the length of food storage time and the level of quality. Different food raw materials have different requirements for temperature.　　

a. Dry storage. The relative humidity of the dry storage food warehouse should be controlled between 50%-60%; if it is a warehouse that stores food such as rice and noodles, the relative temperature should be lower. If the relative humidity of the dry storage warehouse is too high, it should be installed to dehumidify Drying device; the relative humidity is too low and the air is too dry. A humidifier should be used or water should be poured in the warehouse.　　

b. Cold storage. The humidity of fruit and vegetable cold storage should be between 85%-95%; the humidity of meat, dairy products and mixed cold storage should be kept between 75%-85%. If the relative temperature is too high, the food will become slimy , It promotes the growth of bacteria and accelerates the deterioration of food; if the relative humidity is too low, it will cause the food to dry out. You can cover the food with a damp cloth or splash water directly on the food.　　

c. Freezers. The freezer should maintain high humidity, otherwise the dry and cold air will absorb ingredients from the food. Frozen food should be wrapped with anti-moisture or anti-evaporation materials to prevent the food from losing moisture and fat from going bad and smelly.　　 All food warehouses should avoid direct sunlight. Frosted glass should be used for glass windows in warehouses. When selecting artificial lighting, cold light lamps should be selected as much as possible to avoid the increase of the indoor temperature of the warehouse due to the heating of the electric lights.　　

In addition, the storage warehouse should maintain good ventilation. It is best to change the air in the dry storage room four times per hour. The food in the refrigerator and freezer compartments should not be stored against the wall, and should not be placed directly on the floor or stacked on the ceiling to facilitate air circulation.

With the continuous strengthening of the country’s food production quality supervision, the market’s requirements for the quality of food machinery and equipment have gradually increased, and industrial dehumidifiers have been further promoted and are favored by more and more enterprises

Nesta industrial dehumidifier has a built-in humidity sensor, which can sense the workshop environment and automatically adjust the humidity. A variety of industrial dehumidifiers are suitable for different enterprises, factories and workshops, and can be selected according to the applicable area and humidity requirements.
