Cold chain warehousing environment to grasp these five points: product characteristics, cold chain warehousing equipment, processing technology, man-made conditions control and operation management, the following to see the specific bar.
1: control factors of product characteristics include raw material quality and storage resistance. The storage temperature conditions, cooling methods and unit packaging requirements of different raw materials will be different. The quality change of refrigerated products mainly depends on the variable range of temperature controlled by thermometer, the temperature effect of storage items, and even the temperature gradient between surface temperature and internal temperature of storage items will have an impact on their quality. It has been shown that the quality loss of food exposed to normal temperature for one hour may be equivalent to that of food stored at - 20 C for half a year.
2: The control elements of cold chain storage equipment include: quantity, quality, layout and control management mode of cold chain storage equipment, temperature and humidity monitoring system and management operation platform, low temperature environment and storage and transportation tools. In order to ensure that the cold chain storage environment meets the requirements of environmental temperature, humidity, gas composition, hygiene, etc.
3: Control factors of processing conditions include: cold chain storage technology level, packaging conditions and cleanliness and hygiene level.
4: the control elements of human condition include: management mode, express operation and food care.
5: Factors affecting the refrigeration or freezing effect also include biochemical characteristics, cooling methods and refrigeration process conditions, such as the use of manual regulation of the ratio of oxygen and carbon dioxide in the cold chain storage environment, in order to slow down the physiological and biochemical reactions of fresh products, and prolong the shelf life of stored goods. Among them, some factors affect each other, such as cold chain storage equipment conditions have a direct impact on the treatment process, management and operation process.
The above is for you to bring the cold chain warehousing environment to grasp these five specific content, friends from all walks of life, you understand it?
