Specification for quick-frozen warehouse

This specification is applicable to all kinds of cold storage for cold processing and storage of meat, poultry, eggs and aquatic products. I. General Provisions 1. 1 Cold storage is the main component of food cold storage processing enterprises, which is responsible for the frozen processing and storage of perishable foods, and plays a role in promoting the production of agricultural and sideline fisheries, regulating the seasonal supply and demand of the market, and cooperating with the completion of export tasks. 1.2 cold storage has complex structure and high technology content. The use, maintenance and management of cold storage must be carried out in strict accordance with science, and the relevant standards and regulations promulgated by the state should be seriously implemented to achieve safety, hygiene and low consumption. 1.3 leaders at all levels and departments in charge of cold storage should pay special attention to daily maintenance and overhaul while grasping the use, and effectively use and manage the cold storage. 1.4 All workers in the cold storage should study business, master science and technology, love their jobs and take good care of state property. It is necessary to strengthen scientific research, give full play to the role of scientific and technological personnel, adopt advanced technology, and strive to catch up with and surpass the advanced world level. 2. Personnel 2. 1 Enterprises must be equipped with managers and technicians at all levels who have received special education and training, and have professional knowledge, production experience and organizational ability in refrigeration, processing, freezing, electrical appliances and health inspection, and a certain number of technicians, assistant engineers, engineers and senior engineers are responsible for the production, technology, management and scientific research of cold storage. 2.2 cold storage compressor room operators must have a junior high school education or above, after professional training, obtain a certificate, can mount guard operation. 2.3 Business leaders responsible for cold storage production and management should have professional knowledge and practical experience in cold storage management. Professional and technical personnel and operators should be regularly organized for technical study and experience exchange, and take full responsibility for the implementation of this specification. Iii. Use and management of warehouses 3. 1 The use of cold storage should give full play to the freezing and cold storage capacity according to the design requirements, ensure safe production and product quality, and maintain the architectural structure of cold storage. Warehouse management should set up a special team, and the responsibility should be implemented to people. Every warehouse door and every piece of equipment and tools should be taken care of by someone. 3.2 The cold storage is made of heat insulation material, which has the characteristics of being afraid of water, moisture, hot air and running cold. It is necessary to properly check the ice, frost, water, doors and lights. 3.2. 1 The walls, floors, doors and roofs of halls and warehouses should be free of ice, frost or water, and should be removed in time. 3.2.2 In order to improve the refrigeration efficiency, the exhaust pipe and air cooler in the warehouse should be cleaned and cleaned in time. When thawing, it must be operated according to the regulations, and the freezer should be cleared at least once and frosted once. There shall be no accumulated water in the water tray and warehouse of the air cooler. 3.2.3 Water-based operation is strictly prohibited in the cold storage. 3.2.4 Unfreezed goods are not allowed to enter the freezer directly to ensure the quality of goods and prevent the freezer from being damaged. 3.2.5 Cold storage doors should be strictly managed. When goods enter or leave the warehouse, they should be closed at any time. If the warehouse door is damaged, it should be repaired in time to make it open flexibly and close tightly to prevent cold operation. All doors in contact with the outside air should be equipped with air curtains to reduce the convection of cold and hot air. 3.3 Prevent the freezing-thawing cycle, frost brittleness and frost heaving of building structures. 3.3. 1 All kinds of cold storage must be used in accordance with the design requirements, and the cooled and frozen materials shall not be confused. If the freezing room originally designed with cooling technology is changed to one-time freezing, it should be equipped with sufficient refrigeration equipment. If it is really necessary to change the use of cooling room, freezing room and original dual-purpose room, the design department shall design and submit for approval according to the procedure. 3.3.2 When the warehouse is empty, the freezing room and freezer should be kept below -5℃ to prevent freeze-thaw cycle. The temperature of the cooling room should be kept below zero to avoid dripping and getting wet. 3.4 Protect the floor (floor) from freezing and damage. 3.4. 1 Goods shall not be directly laid on the floor or frozen on the mat; Do not use the method of overturning stacking to dismantle the meat pile; It is not allowed to fall on the floor when unhooking and stripping, so as not to break the floor and damage the insulation layer. 3.4.2 The weight of commodity stacking and hanging track shall not exceed the design load. 3.4.3 The temperature of cold storage without floor anti-freezing measures shall not be lower than 0℃ to avoid freezing. 3.4.4 The underground natural ventilation pipeline of cold storage should be kept unblocked, free of water, frost and blockage, and the northern area should be blocked in winter and opened in spring. When using mechanical ventilation or downhole tubing heating equipment, a special person must be appointed to be responsible for regular inspection, and the ventilator, heater and other devices should be turned on in time as required. 3.5 Cold storage must make rational use of storage capacity, constantly summarize and improve the stacking methods of commodities, arrange storage space and stacking height safely and reasonably, and improve the utilization rate of cold storage. Stacking should be firm and tidy, which is convenient for counting, checking and entering and leaving the warehouse. 3.6 Requirements for stacking goods in the warehouse: 0.2m from the ceiling of the refrigerated storage room. 0.3m from the ceiling of the cooling room. 0.3m from the lower side of the top exhaust pipe. 0.2m from the side of the top exhaust pipe. No exhaust pipe 0.2m away from the wall. 0.4m away from the exhaust pipe outside the wall. Distance to the periphery of air cooler1.5m. 0.2m from the bottom of the air duct. 3.7 The warehouse should have reasonable walkways to facilitate the operation, vehicle traffic and equipment maintenance in the warehouse and ensure safety. 3.8 When goods enter and leave the warehouse and work in the warehouse, vehicles and goods must be prevented from colliding with process equipment such as warehouse doors, elevator doors, columns, walls and refrigeration system pipes, and protective devices should be added where collisions are easy to occur. 3.9 The electrical circuits in the warehouse should be maintained regularly to prevent leakage, and the lights should be turned off after leaving the warehouse. 3. 10 cold storage should not use bagged storage system to prevent illegal use.
