Example 1:
referring to fig. 1 to 8, a fresh-keeping and air-changing device for fruits and vegetables comprises an air inlet component and an air outlet component which are communicated with a storage chamber 4, wherein the air inlet component comprises an air mixer 12 and an air pump 13 which are connected in series through a pipeline, the air mixer 12 comprises a tank body 123, the upper end of the tank body 123 is provided with a butt joint 122, the lower end of the tank body 123 is provided with an air outlet, and a mixing mechanism 121 is arranged on the butt joint 122; the mixing mechanism 121 comprises a connecting pipe 1211, a mounting plate 1212 and a mixing chamber 1213 from top to bottom in sequence, the mounting plate 1212 is fixedly connected with the docking port 122, and the mixing chamber 1213 is arranged in the tank 123; a plurality of air outlet holes 1214 are densely distributed on the side surface of the mixing chamber 1213, a rotating shaft 1217 with fan blades 1216 is arranged in the mixing chamber 1213, the upper end of the rotating shaft 1217 is rotatably arranged on the upper part of the mixing chamber 1213 through a hollow support 1215, and the lower end of the rotating shaft 1213 is rotatably arranged on the bottom plate of the mixing chamber 1213.
In this embodiment, as can be seen from fig. 1, a complete controlled atmosphere storage system further includes a nitrogen preparation module and an air preparation module connected to the air intake module, wherein the nitrogen preparation module includes a nitrogen storage tank 10, a nitrogen generator 9 and an air compressor 8 connected in series in sequence through a pipeline; the air preparation assembly comprises an air storage tank 11 and an air compressor 8 which are sequentially connected in series through a pipeline.
Preferably, an air filter 7 is connected to the air inlet end of the air compressor 8. The air filter 7 can filter air entering the air compressor 8, so as to remove impurities and pollutants contained in the air, and ensure that nitrogen and air prepared by the air compressor 8 are fresh and clean.
The nitrogen preparation assembly and the air preparation assembly respectively compress and store prepared gas in gas storage tanks and control the opening and closing of the gas storage tanks through valves. After the valve is opened, the high-pressure nitrogen and the high-pressure air in the air storage tank are converged by the pipeline and then enter the air mixer 12. The high pressure gas will push the fan blade 1216 to rotate, and the rotating fan blade 1216 will relatively stir the gas to mix it thoroughly, the mixed gas will be discharged from the gas outlet 1214 on the side of the mixing chamber 1213 to form multiple gas flows, and the multiple gas flows will be mixed in the tank 123, further improving the gas mixing effect. Finally, the fully mixed nitrogen-air mixture is discharged through the air outlet 124 under the action of the air pump 13.
Further, bearings are arranged at the joints of the hollow support 1215, the bottom plate of the mixing chamber 1213 and the rotating shaft 1217, so that the rotating shaft 1217 rotates more stably and smoothly.
Further, the hollow support 1215 is installed in an interference fit with the inner cavity of the mixing chamber 1213, so that the hollow support 1215 and the rotating shaft 1217 in the mixing chamber 1213 can be conveniently disassembled and assembled.
Example 2:
referring to fig. 1 to 8, the present embodiment is further optimized on the basis of embodiment 1, specifically:
the exhaust assembly comprises a vacuum pump which is communicated with the storage chamber 4 through an exhaust pipe 5, and the air inlet assembly is communicated with the storage chamber 4 through an air inlet pipe 2.
In this embodiment, the vacuum pump is used as the exhaust means, and the reduced-pressure storage can be realized in addition to the ordinary gas storage.
The decompression storage is a special air-conditioning storage method, and its basic principle is that on the basis of low temperature the fruits and vegetables are placed in a closed container, and the partial air in the container is pumped out to make the internal air pressure reduce to a certain extent and attain a certain vacuum degree, and at the same time the fresh air is fed in by means of pressure regulator, so that the whole system can continuously make gas exchange so as to maintain the dynamic constant pressure in the storage container and a certain humidity environment. Because the pressure of the internal air is reduced, the oxygen partial pressure of the internal environment is also reduced, the respiration intensity of the fruits and vegetables is further reduced, and the biosynthesis of ethylene is inhibited. The low pressure can delay the decomposition of chlorophyll, inhibit the synthesis of carotenoid and lycopene, and slow down the hydrolysis of starch, the increase of sugar and the consumption of acid, thereby delaying the maturation and aging of fruits and vegetables and maintaining the freshness of fruits and vegetables for a longer time.
Furthermore, the pipeline at the connection part of the air inlet pipe 2 and the air outlet pipe 5 and the storage chamber 4 is of a square structure, and the air inlet pipe 2 and the air outlet pipe 5 are both arranged in the air pipe box 3. Convection of the intake duct 2 and the exhaust duct 5 with the outside air is avoided by the zigzag duct design of the intake duct 2 and the exhaust duct 5 connected to the storage compartment 4.
Further, the air inlet of the air inlet pipe 2 and the air outlet of the air outlet pipe 5 are arranged on two opposite sides of the storage chamber 4, the air inlet is positioned at the top of the storage chamber 4, and the air outlet is positioned at the bottom of the storage chamber 4. Thereby increasing the air flow path in the storage compartment 4 and thus enhancing the replacement effect of the air in the storage compartment 4.
Further, the air inlet pipe 2 is connected with a humidifying device 14 through a pipeline, and the humidifying device 14 is used for preparing water mist to adjust the humidity of the storage chamber 4. Because the air exhaust assembly can take away the water in the storage chamber 4, the humidity in the storage chamber 4 can be adjusted through the humidifying device 14, and the fruits and vegetables are prevented from being shriveled and wilted due to water loss.
Furthermore, the air inlet pipe 2 is provided with a refrigeration device 1, and the refrigeration device 1 is used for cooling the gas in the air inlet pipe 2. The gas flowing through the gas inlet pipe 2 is cooled by the refrigerating equipment 1 to become low-temperature gas, and after the low-temperature gas enters the storage chamber 4, the problem in the storage chamber 4 can be reduced, low-temperature storage is realized, and the fruit and vegetable fresh-keeping effect is further improved.
The other parts of this embodiment are the same as embodiment 1, and are not described herein again.
The embodiment of the present invention is the above.
