Description

Technical Field

[0001] The utility model relates to the technical field of fresh-keeping, in particular to a multi-parameter cooperative control device and a fresh-keeping control system. Background Art

[0002] Fresh-keeping technology is a technology that prolongs the freshness of fruits and vegetables. Currently, common fresh-keeping technologies include refrigeration, freezing, edible film, controlled atmosphere, biological, and chemical preservation.

[0003] Refrigerated preservation technology is a technology that prolongs the shelf life and maintains freshness of food by storing it in a low-temperature environment. The shelf life is usually 5-7 days. Frozen preservation technology is a technology that uses equipment for refrigeration, which can be artificially controlled and maintain a stable low temperature. The shelf life is usually 6-8 days. Edible film preservation technology is a technology that forms a protective layer on the surface of food to block the entry of air, moisture and bacteria, thereby extending the shelf life of food. The shelf life is 2-3 days. Controlled atmosphere preservation technology is a method of extending the shelf life of food by adjusting the gas composition in the atmosphere around the food. The shelf life is 5-7 days. Biological preservation technology is a technology that uses the active ingredients of microorganisms, enzymes or other organisms to delay oxidation and extend the shelf life of food. The shelf life is 10-13 days. Chemical preservation technology is the use of chemical preservatives for preservation, and the shelf life is 3-5 days.

[0004] Refrigerated preservation consumes a lot of energy, has a short preservation time, and cannot maintain appropriate humidity and carbon dioxide concentration; edible film has a short preservation time and poor effect; controlled atmosphere preservation has high requirements for gas ratio and sealing of packaging materials, and the cost is relatively high; biological preservation has high requirements for microorganisms, and although the preservation time is long, the cost is high. Although chemical preservation is simple to operate, it is easy to cause chemical residues, affect human health, and pollute the environment. Moreover, none of the above technologies can coordinate the control of temperature, humidity, and carbon dioxide concentration to keep crops in the best preservation state.

[0005] From the above, it can be seen that the current mainstream solutions have obvious shortcomings and cannot be fully commercialized and promoted. No single preservation method can meet the existing preservation requirements. There is an urgent need for a preservation (method) device that can coordinate the control of temperature, humidity, and carbon dioxide concentration, and a material that can simultaneously meet the coordinated control of temperature, humidity, and carbon dioxide concentration, and that has the practical advantages of comprehensive safety, greenness, high efficiency, low cost, and long preservation time to steadily promote the development of the preservation industry.

[0006] The existing technology has at least the following technical defects: 1. Limitation of coordinated control of temperature, humidity and carbon dioxide concentration: The existing preservation technology cannot achieve coordinated control of temperature, humidity and carbon dioxide concentration, and the preservation effect is poor and the efficiency is low. 2. Limitation of residual hazardous substances: Some chemical preservatives and additives may remain in food, posing certain safety hazards and causing consumer concerns. 3. Limitation of high preservation cost: The materials used in single atmosphere preservation technology and biological preservation technology are expensive and costly, and are not suitable for large-scale batch preservation.

Then, by adjusting the temperature and pressure of the environment in which the carbon dioxide hydrate is located, the cold, moisture and carbon dioxide generated by the decomposition of carbon dioxide hydrate can be promoted to achieve the control of the fresh-keeping environment and achieve the purpose of fresh-keeping.

[0102] In summary, the embodiments of the present disclosure enable comprehensive control of temperature, humidity, and carbon dioxide concentration, while being easy to generate, transport, store, and intelligently control.

[0103] Compared with the existing technology, under the premise of ensuring that the preservation technology is not lower than the existing average level and safety, the disclosed embodiment has the following obvious advantages: long preservation time and good effect: this equipment can coordinate the control of temperature, humidity and carbon dioxide concentration, effectively inhibit the aerobic respiration of plants while maintaining the color and taste of plants to the greatest extent, delay the loss of nutrients, and greatly extend the preservation time with excellent effect. Intelligent coordinated control of temperature, humidity and carbon dioxide concentration: the equipment can control the temperature and pressure of the hydrate environment under the control of the program according to the needs through the intelligent control terminal, so that the carbon dioxide hydrate can be stably and orderly decomposed, and the preservation efficiency is greatly improved while accurately controlling the preservation conditions. Low generation cost: the generation and storage process of carbon dioxide hydrate only needs to meet 2~5℃ and 1~2MPa, avoiding the energy consumption of high pressure and high temperature conditions for the traditional generation of carbon dioxide hydrate. Green, safe and pollution-free: the raw material for the generation of this hydrate is carbon dioxide, which realizes the resource utilization of carbon dioxide, mild reaction conditions, low risk factor, no harmful substances in the whole process, and solves pollution from the source. The operation method is convenient: adding spiral fins and peripheral coils to the equipment can greatly increase the reaction rate, so that when carbon dioxide hydrate is generated, only the temperature and pressure control unit needs to be started, and the unit needs to be shut down when carbon dioxide hydrate is released. And the detection and control device can control the operation of the temperature and pressure control unit according to environmental requirements. The raw materials are widely available and cheap, and the reaction catalysts can be reused at low cost. Carbon dioxide hydrate has a large gas storage capacity: Carbon dioxide hydrate has a huge gas storage capacity. 1 volume of water can store 175 volumes of carbon dioxide. The generated carbon dioxide hydrate only has carbon dioxide and water when it decomposes, and a part of cold energy is generated (the cold energy is collected to the cold storage layer through the cold energy collection layer for temperature regulation).

[0104] The embodiments of the present disclosure are based on the generation and storage of carbon dioxide hydrate by the hydrate method and a three-in-one coordinated control technology for preservative release that integrates temperature, humidity, and carbon dioxide concentration. Its generation and application conditions are mild, and a large amount of carbon dioxide gas can be stored, avoiding the energy consumption of high pressure and high temperature conditions for the traditional generation of carbon dioxide hydrates. In addition, carbon dioxide hydrates can be stably decomposed to ensure the safety of preservation. The equipment is intelligently controlled by an intelligent control terminal to control the temperature, humidity, and carbon dioxide concentration of the preservation environment to maintain dynamic balance within an appropriate range. This device can be maintained under low temperature and low pressure conditions, and a small amount of water can absorb a large amount of carbon dioxide. The carbon dioxide hydrate generation, release, and temperature, humidity, and carbon dioxide concentration coordinated control device is simple in principle, easy to operate, and low in cost.
