To strengthen scientific research, give full play to the role of scientific and technological personnel, the use of advanced technology, and strive to catch up with the world's advanced level. II. Personnel 2.1 Enterprises must be equipped with managers and technicians at all levels who have received special education and training in accordance with the relevant regulations, and have professional knowledge, production experience and organizational ability in cold storage, processing, refrigeration, electrical appliances, sanitation and inspection, etc., and a certain number of technicians, assistant engineers, engineers and senior engineers are in charge of production, technology, management and scientific research of the cold storage. 2.2 Compressor room operators of the cold storage must be educated above junior high school, and after professional training and obtaining qualified certificates before they can be put on duty to operate. 2.3 The enterprise leaders responsible for the production and management of cold storage should have professional knowledge and practical experience in cold storage management. To regularly organize professional and technical personnel and operators for technical learning and experience exchange, to the implementation of this specification is fully responsible for. Third, the use of the warehouse management 3.1 The use of cold storage, should be in accordance with the design requirements, give full play to the freezing, refrigeration capacity to ensure safe production and product quality, maintenance of cold storage building structures. Treasury management to set up a specialized team, the responsibility to implement, each library door, each piece of equipment and tools, should be responsible for someone. 3.2 Cold storage is built with insulating materials, with the fear of water, fear of moisture, fear of heat, fear of running cold characteristics, to put the ice, frost, water, door, light five off. 3.2.1 Through the hall and the warehouse walls, floor, door, roof, etc. shall not have ice, frost, water, there should be removed in a timely manner. 3.2.2 The library exhaust pipe and chiller should be timely frost, frost, in order to improve the refrigeration efficiency. Frost must be operated in accordance with the procedures, freezing room at least to do a clear library, a frost. There should be no water in the water tray of the chiller or in the warehouse. 3.2.3 Cold storage is strictly prohibited multi-water operations. 3.2.4 No frozen goods are not allowed to go straight into the freezing room to ensure the quality of goods and prevent damage to the cold storage. 3.2.5 To strictly manage the cold storage door, goods in and out of the warehouse, to close the door at any time, if the door is damaged to repair in a timely manner, so that the opening of the flexible, close tightly, to prevent running cold. Any door that touches the outside air should be equipped with an air curtain to reduce the convection of hot and cold air. 3.3 Prevent the building structure from freeze-thaw cycle, freeze crisp, freeze dropsy. 3.3.1 All kinds of cold storage storage room must be used according to the design of the specified purpose, cooling things, frozen things frozen room can not be confused use. The original design of the cooling process of the freezing room, such as a freezing when changed to be equipped with adequate refrigeration equipment. If it is necessary to change the use of the cold storage room for cooled materials, the frozen materials cold storage room, or the dual-use room of the original design, it shall be designed by the design department and submitted for approval according to the procedure. 3.3.2 When the warehouse is empty, the freezing room and the freezing room should be kept below -5℃ to prevent freezing and thawing cycles. The cold storage room for cooled materials should be kept below zero temperature to avoid moisture dripping inside the warehouse. 3.4 Protect the floor from dropsy and damage. 3.4.1 shall not put the commodity directly spread on the floor or mat on the mat and so on freezing; demolition of meat pallet shall not be used inverted pallet method; off the hook and off the plate is not allowed to fall in the floor, so as to avoid smashing the floor, damage to the heat insulation layer. 3.4.2 Commodity stacking, hanging rails hanging, its weight shall not exceed the design load. 3.4.3 There is no floor anti-freezing measures of cooling material cold storage room, its library temperature shall not be lower than 0 ℃, so as not to freeze dropsy. 3.4.4 Cold storage underground natural air ducts should be kept open, not water, frost, not blocked, the northern region to do winter blocking spring open. The use of mechanical ventilation or underground tubing heating and other equipment, to designate a person responsible for regular checks, according to the requirements of the timely opening of the ventilator, heater and other devices. 3.5 Cold storage must make reasonable use of warehouse capacity, constantly summarize and improve the method of commodity stacking, safety, reasonable arrangement of cargo space and stacking height, improve the utilization rate of cold storage. Stacking should be firm and neat, and it is convenient for inventory, inspection, and entering and leaving the warehouse. 3.6 Requirements for stacking of goods in the warehouse: 0.2 meters from the roof of the cold storage room for frozen goods. 0.3 meters from the roof of the cold storage room of cooled materials. 0.3 meters from the lower side of the top pipe. 0.2 meters from the horizontal side of the top discharge pipe. 0.2 m from the wall without a drain pipe. 0.4 m from the outer side of the wall discharge pipe. 1.5 m from around the chiller. 0.2 m from the bottom of the duct. 3.7 The warehouse should leave a reasonable walkway, easy to operate the warehouse, vehicle through, equipment maintenance, to ensure safety. 3.8 Commodities in and out of the warehouse and warehouse operations, to prevent the means of transport and commodities collision warehouse doors, elevator doors, columns, walls and refrigeration systems, piping and other process equipment, in the collision prone, should be added to the protective device. 3.9 The electrical wiring in the warehouse should be maintained frequently to prevent leakage of electricity, and the lights should be turned off when leaving the warehouse. 3.10 Cold storage is not suitable for the use of packaged storage system to prevent unauthorized use.
