Design and construction of cold storage and air conditioning cold preservation principle and difference
The principle of fresh-keeping of cold storage is to improve the relative humidity of the cold storage environment on the basis of cold storage, and to artificially adjust the specific gas components in the cold storage to effectively inhibit the breathing and evaporation under the premise of maintaining the normal physiological activities of the fruit. The effects of hormones, microorganisms and enzymes delay the physiological metabolism, delay the post-aging aging process and prevent deterioration*, so that the fruit can be preserved for a longer period of time. The gas regulation of the air-conditioned cold storage is to reduce the oxygen concentration in the air from 21% to 3%~5%, that is, the fresh-keeping cold storage is based on the high-temperature cold storage, plus a set of air-conditioning system, using the temperature and controlling the oxygen content. A combination of aspects to achieve inhibition of fruit and vegetable post-harvest breathing.
Cold storage refers to facilities that are cooled by various equipment, can be artificially controlled, and remain stable at low temperatures. Refrigeration systems, control devices, insulated warehouses, and ancillary buildings are the basic components of cold storage.
The cold storage emphasizes freezing and freezing, generally placing popsicles, ice cubes, cold meat, frozen fish and the like. The atmosphere library generally emphasizes preservation, and generally puts fruits and vegetables.
The air-conditioning warehouse is generally composed of an airtight storage system, a gas-conditioning system, a refrigeration system, a humidification system, a pressure balance system, and an automatic detection and control system for temperature, humidity, O2, CO2, and gas.
Shanghai Xueyi Refrigeration Technology Development Co., Ltd. is a refrigeration company integrating large, medium and small cold storage design, installation, service and cold chain. Focus on cold storage for more than ten years, the main large, medium and small high temperature fruit and vegetable warehouse, cryopreservation library, frozen storage, fruit and vegetable flower atmosphere storage library, electronic instrument constant temperature library, medical cold storage, combination library, civil engineering library, large and medium cold storage Maintenance, cold storage maintenance, etc.
Electronic touch screen Safe Box is a safe storage device that uses a touch screen interface for easy access and management. It is designed to protect the safety of valuables, important documents and personal belongings.
The characteristics of electronic touch screen safe box may include: 1; Touch screen interface: safe box is equipped with touch screen display, which can input passwords or access various functions. 2. Safe locking mechanism: safe box electronic lock system is adopted, password or biometric authentication (such as finger print or facial recognition) is required to open it. 3. Multi-user access: some touch screen safe box allow multiple users to have their own unique passwords or biometric profiles for personal access. 4. Alarm system: if you enter an incorrect password multiple times or someone tries to tamper with the safe box, an alarm will be triggered. Emergency backup access: in the event of forgetting the password or failing, some safe box have backup keys or secondary access methods in case of emergency.6. Internal organization: Electronic Safe may have adjustable or movable shelves, compartments or partitions to help effectively organize and store different articles. 7. Battery Power supply: safe box are generally powered by batteries, and the normal operation of the safe box can be ensured even if the power is cut off. 8. Installation options: safe box may have pre-drilling or hardware installation to safely install on the wall or floor. In general, electronic touch screen safe box provide convenient, safe and secure protection for individuals or enterprises to protect their valuable property.
