With the improvement of people’s quality of life With the improvement of storage conditions, people have put forward higher requirements for the storage of fruits, vegetables, food, flowers, etc., and the temperature and humidity in the warehouse must be strictly controlled. When the humidity in the cold storage is insufficient, the relatively dry air will absorb moisture from the stored fruits and vegetables, causing the fruits and vegetables to lose water and dry out. It is appropriate to control the relative humidity of the cold storage between ~R.
The goods stored in cold storage generally contain a certain amount of moisture. How to keep the moisture from being lost? First of all, we must ensure that the humidity in the air is sufficient. This is the primary condition.
Cold storage is mainly used for food preservation. With the development of freezing technology in our country, more and more foods are kept fresh for longer and longer periods. Especially some vegetables and fruits with a relatively short shelf life. With the development of freezing technology, these vegetables and fruits can also be distributed all over the country.
Mechanical freezing processing and refrigeration, through artificial refrigeration, keep the room at a certain low temperature. The walls, floors and flat roofs of cold storage buildings are covered with a certain thickness of thermal insulation materials to reduce heat transfer from the outside of the cold storage. A place for storing fresh agricultural products, cold storage warehouse. Its function is to maintain the stability of low-temperature environments, and the thermal insulation performance is usually referred to as heat preservation. A good thermal insulation structure of a cold storage room can maximize the amount of cold energy produced by the cold storage unit and prevent it from leaking outside the cold storage. In other words, it can minimize the leakage of heat from outside the cold storage into the cold storage. This is also the main difference between cold storage and ordinary houses. place.
Equipped with a mechanical cold storage unit, this method of storing fruits is in a well-insulated building. And according to the storage temperature, humidity and ventilation requirements of fruit varieties, the cold storage system is artificially adjusted and controlled, so the storage time is longer and the effect is better. Thereby absorbing heat, the principle of mechanical cold storage refrigeration. Mechanical cold storage uses a liquid (refrigerant) with a very low vaporization temperature to evaporate into a gas under low pressure. In addition to having a low boiling point to achieve the purpose of cooling, the refrigerants used in cold storage must also be harmless to human organs, not corrosive to metals, have no danger of burning or explosion, not chemically react with lubricants, and have good adsorption properties. Thermal performance, evaporation heat absorption, low pressure in the high-pressure condensation system, low viscosity, low price, few failures, etc. Anhui Jinxue Refrigeration Equipment Co., Ltd.
