Description

Technical Field

[0001] This application relates to the field of storage devices, and more specifically, to a fresh freeze-drying storage device. Background Technology

[0002] Generally speaking, freeze-dried foods are rapidly frozen and dehydrated in a vacuum, preserving their original color, aroma, flavor, nutritional components, and appearance. They also have good rehydration properties and contain no additives, making them ideal natural and hygienic foods.

[0003] Freeze-dried products are relatively dry, and cold storage is required for their storage. However, during long-term use, frost often forms inside cold storage facilities, indicating that the air inside is quite humid. This humid environment is not conducive to the storage of freeze-dried products. Since some cold storage facilities do not have air drying and dehumidification structures, the freeze-dried products eventually absorb moisture from the cold storage, causing them to deteriorate. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a fresh freeze-drying storage device, which aims to improve the problem that a relatively humid environment is not conducive to the storage of freeze-dried products. Since some cold storage facilities are not equipped with air drying and dehumidification structures, freeze-dried products will eventually absorb moisture from the inside of the cold storage, causing the freeze-dried products to deteriorate.

[0005] This application provides a fresh food freeze-drying storage device, including a cold storage and a circulating air assembly. A refrigeration structure is provided on one side of the cold storage, with an air inlet on one side and an exhaust / heat dissipation end on the other side. The circulating air assembly includes a first fan, a second fan, a filter box, a sliding plate, a filter element, and a lifting sealing door. The lifting sealing door is slidably connected to the middle of the filter box. The filter box has a filtration zone and a drying zone. The input end of the first fan is connected to the exhaust / heat dissipation end, and the output end of the first fan is connected to the drying zone. The output end of the second fan is connected to the air inlet, and the input end of the second fan is connected to one side of the filtration zone. The other side of the filtration zone is connected to the cold storage. The sliding end of the sliding plate is located inside the filter box, and the filter element is fixedly connected to the sliding end of the sliding plate.

[0006] In one specific implementation, the first fan input end is provided with an air collecting hood and a first connecting pipe. One end of the first connecting pipe is connected to the air collecting hood, the air collecting hood is fixedly installed on one side of the exhaust heat dissipation end, and the other end of the first connecting pipe is connected to the first fan input end.

[0007] In one specific implementation, the first fan output end is provided with a second connecting pipe, the second connecting pipe is provided with a three-way pipe, the three-way pipe is respectively provided with a first solenoid valve and a second solenoid valve, and the three-way pipe is connected to the drying zone.

[0008] In one specific implementation, the sliding plate includes a plate body and a first telescopic member, the end of the first telescopic member being fixedly connected to the filter cartridge box, the output end of the first telescopic member being fixedly connected to the bottom of the plate body, the plate body being slidably connected to the bottom of the filter cartridge box, and the filter cartridge being fixedly connected to the plate body.

[0009] In one specific implementation, the plate body has a sealing groove that matches the lifting sealing door, and the bottom of the lifting sealing door is inserted into the sealing groove.

[0010] In one specific implementation, two filter elements are provided, with a sealing groove spaced between the two filter elements.

[0011] In one specific implementation, the lifting sealing door includes a door body and a second telescopic member. The door body is slidably connected to the filter box, one side of the second telescopic member is fixedly connected to the upper part of the filter box, and the output end of the second telescopic member is fixedly connected to the upper part of the door body.

[0012] In one specific implementation, the filter box is provided with an air outlet slot on one side of the drying zone.

[0013] Beneficial Effects: This application provides a fresh freeze-drying storage device. During use, the cold storage is normally opened, and the refrigeration structure is activated. The first fan input draws hot air from the refrigeration structure and delivers it to the drying zone, where a filter element is dried. Meanwhile, the second fan input draws air from the filtration zone, dehumidifying the air inside the cold storage before delivering it to the air inlet of the refrigeration structure. When the moisture content of the filter element in the filtration zone increases, the lifting sealing door rises, and the sliding end of the sliding plate moves the filter element, moving it from the filtration zone to the drying zone. Thus, the filter element in the drying zone is moved to the filtration zone, allowing for the alternating use of the two filter elements. Throughout the process, the air inside the cold storage is dried, reducing humidity, decreasing water absorption during freeze-drying, and minimizing spoilage. Attached Figure Description

The input end of the first fan 210 is connected to the exhaust heat dissipation end 112, and the output end of the first fan 210 is connected to the drying area 232. 2. The output end of the second fan 220 is connected to the air inlet 111, the input end of the second fan 220 is connected to one side of the filter area 231, and the other side of the filter area 231 is connected to the cold storage 100. The sliding end of the sliding plate 240 is located inside the filter element box 230, and the filter element 250 is fixedly connected to the sliding end of the sliding plate 240. The input end of the first fan 210 is provided with an air collecting hood 211 and a first connecting pipe 212. One end of the first connecting pipe 212 is connected to the air collecting hood 211, and the air collecting hood 211 is fixedly installed on one side of the exhaust heat dissipation end 112. The other end of the first connecting pipe 212 is connected to the input end of the first fan 210.

[0024] The first fan 210 has a second connecting pipe 213 at its output end. The second connecting pipe 213 has a three-way pipe 214, which is equipped with a first solenoid valve 215 and a second solenoid valve 216. The three-way pipe 214 communicates with the drying zone 232. The sliding plate 240 includes a plate body 241 and a first telescopic member 242. The end of the first telescopic member 242 is fixedly connected to the filter cartridge box 230, and the output end of the first telescopic member 242 is fixedly connected to the bottom of the plate body 241. The plate body 241 is slidably connected to the bottom of the filter cartridge box 230. The filter element 250 is fixedly connected to the plate body 241. 1. A sealing groove 243 matching the lifting sealing door 260 is provided. The bottom of the lifting sealing door 260 is inserted into the sealing groove 243. There are two filter elements 250, with a sealing groove 243 between the two filter elements 250. The lifting sealing door 260 includes a door body 261 and a second telescopic member 262. The door body 261 is slidably connected to the filter element box 230. One side of the second telescopic member 262 is fixedly connected to the upper part of the filter element box 230. The output end of the second telescopic member 262 is fixedly connected to the upper part of the door body 261. The filter element box 230 is located on one side of the drying area 232 and has an air outlet hole 234.

[0025] The working principle of this fresh food freeze-drying storage device is as follows: When the cold storage 100 is started, the refrigeration structure 110 simultaneously begins refrigeration. The first fan 210 draws out the hot air generated at the exhaust heat dissipation end 112 of the refrigeration structure 110 through the input end formed by the air collector 211 and the first connecting pipe 212. The hot air is then directionally transported to the drying zone 232 of the filter box 230 through the second connecting pipe 213 and the three-way pipe 214. In the drying zone 232, the hot air efficiently dries the filter element 250 through the air outlet slots 234. At the same time, the second fan 220 draws air from the filtration zone 231 of the filter box 230 through the pipeline. The filtration zone 231 then draws in air from the cold storage 100 through the pipeline, utilizing the adsorption characteristics of the filter element 250 to complete the dehumidification work. The dehumidified and dried air is finally transported to the air inlet end 111 of the refrigeration structure 110 through the pipeline, forming a complete air circulation loop. As the filtration process continues, when the moisture content of the filter element 250 in the filtration zone 231 reaches a set threshold, the lifting and sealing door 260, composed of the door body 261 and the second telescopic component 262, automatically rises. The sliding plate 240, composed of the plate body 241, the first telescopic component 242, and the sealing groove 243, then starts, driving the filter element 250 to slide along the track. This precise mechanical transmission system realizes the exchange of positions of the filter element 250 between the filtration zone 231 and the drying zone 232. The filter element 250, which was originally in the filtration zone 231, is transferred to the drying zone 232 for drying, while the dried filter element 250 enters the filtration zone 231 to continue performing the dehumidification task. Through this alternating operation mode of the dual filter elements 250, the system can continuously dry the air in the cold storage 100, significantly reducing the humidity in the storage, effectively inhibiting the moisture absorption of freeze-dried products, and reducing the risk of deterioration caused by humidity from the root.

[0026] It should be noted that both the first telescopic component 242 and the second telescopic component 262 are electric push rods.
