Description

Technical Field

[0001] This invention relates to a cooling and storage device for enoki mushrooms, and more particularly to a cooling and storage device for enoki mushrooms and its method of use, belonging to the field of enoki mushroom storage technology. Background Technology

[0002] Enoki mushrooms are a common edible fungus, belonging to the phylum Basidiomycota, order Agaricales, family Tricholomataceae, and genus *Flammulina*. They are renowned for their tender caps, crisp stems, rich nutritional value, and delicious flavor. Enoki mushrooms are not only delicious but also highly nutritious, making them a popular ingredient in cold dishes and hot pot.

[0003] After harvesting, enoki mushrooms need to be further processed according to demand. During the processing, since there are a large number of enoki mushrooms, if not all of them can be processed in time, some of them need to be stored. In terms of storage methods, most people choose cooling storage to extend the storage time of enoki mushrooms and prevent them from spoiling.

[0004] Therefore, cooling and refrigeration storage equipment is used for cooling and storage, with cold storage being the most common type. Existing cold storage facilities are generally large in size and require a continuous supply of cold air to maintain the low temperature inside. These facilities also have ventilation fans to circulate air, reduce temperature, and dehumidify. However, due to the ventilation fan structure, some cold air is exhausted through the channels in the fan structure. Furthermore, the doors are frequently opened when staff retrieve goods, further exacerbating the cold air loss. Since cold storage facilities often have poor insulation, the cold air is lost quickly, requiring the cooling equipment to continuously or frequently supply cold air to maintain the low temperature, resulting in higher overall energy consumption.

[0005] Therefore, it is urgent to improve the cooling and storage equipment for enoki mushrooms to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a cooling and storage device for enoki mushrooms. After cooling is completed, the ventilation fan structure is sealed, sealing the entire ventilation duct. When retrieving the mushrooms, the storage unit is divided into a storage area and a waiting area by a partition, which maintains the temperature inside the storage unit, prevents cold air from escaping, and improves the durability of the low temperature. Consequently, the power consumption of the equipment is greatly reduced, achieving an energy-saving effect.

[0007] To achieve the above objectives, the main technical solution adopted by the present invention includes: a cooling and storage device for enoki mushrooms, comprising a storage body, ventilation fan structures provided on both sides of the storage body, a partition provided inside the storage body, several layers of enoki mushroom racks slidably arranged on the inner side of the partition, a box slidably arranged on the partition, a sealed and heat-insulating door slidably arranged on the front end of the storage body, and refrigeration compressors extending into the storage body provided on both sides of the storage body; the ventilation fan structure includes a ventilation duct, a ventilation fan arranged inside the ventilation duct, and an adjustment window structure arranged inside the ventilation duct for sealing the ventilation duct.

[0009] Preferably, the driving mechanism includes a drive motor disposed on the upper end face of the ventilation duct, a first sprocket disposed on the output end of the drive motor, and a plurality of second sprockets. One end of the sealing plate is provided with a rotating rod extending through to the outside of the ventilation duct. The plurality of second sprockets are respectively connected to the plurality of rotating rods, and the plurality of second sprockets are connected to the first sprockets by a chain.

[0010] Preferably, the exhaust port of the refrigeration compressor is close to the enoki mushroom placement rack. The enoki mushroom placement rack includes an electric slide rail disposed on both sides of the storage body, a sliding support block connected to the electric slide rail, and a placement rack supported and rotatably connected by two of the sliding support blocks. One of the sliding support blocks is provided with a second drive mechanism for driving the placement rack to rotate and adjust.

[0011] Preferably, the second drive mechanism includes a second drive motor disposed inside the sliding support block and a connecting column for connecting the second drive motor and the placement frame. Another sliding support block, located away from the second drive motor, is rotatably connected to a second connecting column connected to the placement frame. The placement frame has two symmetrically arranged discharge ports at one end near the box body.

[0012] Preferably, the lower end face of the partition is provided with a through groove for sliding the box body, the upper end face inside the through groove is provided with a second electric slide rail for driving the box body to slide, the lower end face of the second electric slide rail is provided with a moving wheel, the two sides of the box body are provided with a second sealing plate, and the inner wall of the second sealing plate is provided with a heat insulation cotton layer.

[0013] Preferably, the front end face of the warehouse body is provided with a door groove, and a first sliding groove and a second sliding groove are respectively provided on both sides of the door groove. The first sliding groove and the second sliding groove are staggered from each other. The sealing and heat-insulating door includes a first heat-insulating sealing door and a second heat-insulating sealing door. The first heat-insulating sealing door and the second heat-insulating sealing door are slidably disposed in the first sliding groove and the second sliding groove, respectively.

[0014] Preferably, the first sliding groove is provided with a plurality of first electric telescopic rods, which are connected to the first thermal insulation and sealing door. The second sliding groove is provided with a plurality of second electric telescopic rods, which are connected to the second thermal insulation and sealing door.

[0015] Preferably, a number of temperature sensors are distributed inside the storage body, a combination lock body is provided on the outer side of the second insulated and sealed door, and a hidden groove for hiding the combination lock body is provided on the second insulated and sealed door. A temperature zone monitor is provided in the hidden groove, and the number of temperature sensors are all connected to the temperature zone monitor.

[0016] A method for using a cooling and storage device for enoki mushrooms includes the following steps:

[0017] S1: When cooling the storage area on one side of the warehouse, cold air is delivered to the storage area through the refrigeration compressor, and the internal temperature is reduced and dehumidified by the ventilation fan structure at the same time. Several temperature sensors and temperature zone monitors are used to monitor the internal temperature. When the required temperature is reached, the cooling is stopped.

[0018] S2: Then the drive motor will be used to start and drive the first sprocket, using the chain...

[0019] This drives several second sprockets to rotate, thereby driving several sealing plates to rotate synchronously until the multiple sealing plates are adjusted to seal the entire ventilation duct, thereby achieving heat preservation inside the warehouse, preventing cold air from escaping, and improving the durability of low temperature.

[0020] S3: When it is necessary to retrieve the enoki mushrooms stored inside the storage area, the first and second insulated sealing doors are slid open using the first and second electric telescopic rods. Workers enter the waiting area, and then the electric slide rail drives the placement rack to slide close to the container. The second drive motor is then activated, causing the placement rack to rotate and tilt closer to the container, allowing the enoki mushrooms on the rack to slide out through the two discharge ports into the container. The second electric slide rail then drives the container containing the enoki mushrooms to slide back to the waiting area. At this point, the side of the container away from the waiting area is sealed by the second sealing plate, maintaining the temperature inside the storage area and preventing cold air from escaping. Workers then remove the mushrooms. After removal, the second electric slide rail is used again to reset the container. Upon reset, the second sealing plate on the side away from the enoki mushroom placement rack also seals the passageway, maintaining the temperature inside the storage area, preventing cold air from escaping, and improving the durability of the low-temperature operation.

[0021] The present invention has at least the following beneficial effects:

[0022] 1. The drive motor activates the first sprocket, which in turn drives several second sprockets to rotate. This, in turn, causes several sealing plates to rotate synchronously until they seal the entire ventilation duct, maintaining the temperature inside the storage area, preventing cold air from escaping, and improving the durability of the low temperature. When it is necessary to retrieve the enoki mushrooms stored inside, the sealed insulated door is slid open, and staff enter the waiting area. Then, the electric slide rail moves the placement rack closer to the storage unit. The second drive motor is then activated, causing the placement rack to rotate and tilt closer to the storage unit, thus allowing the mushrooms to be placed inside. The enoki mushrooms placed on the rack are slid into the container through two discharge ports. Then, the container containing the enoki mushrooms is slid to the waiting area using a second electric slide rail. At this time, the side of the container away from the waiting area is sealed by a second sealing plate to maintain the temperature inside the container and prevent cold air from escaping. After that, the staff takes the mushrooms out. After taking them out, the container is reset again using the second electric slide rail. After resetting, the second sealing plate on the side away from the enoki mushroom rack will also seal the passage, thus maintaining the temperature inside the container, preventing cold air from escaping, and improving the durability of the low temperature. Consequently, the power consumption of the equipment will be greatly reduced, achieving energy-saving effects. Attached Figure Description

[0034] like Figures 1-8As shown, the enoki mushroom cooling and storage device provided in this embodiment includes a storage body 1. Both sides of the storage body 1 are provided with ventilation fan structures 2. The storage body 1 is provided with a partition 3. Several layers of enoki mushroom placement racks 4 are slidably arranged on the inner side of the partition 3. A box body 5 is slidably arranged on the partition 3. The enoki mushroom placement rack 4 includes an electric slide rail 14 arranged on both sides of the storage body 1, a sliding support block 15 connected to the electric slide rail 14, and a placement rack 16 supported and rotatably connected by two sliding support blocks 15. One of the sliding support blocks 15 is provided with a second drive mechanism for driving the placement rack 16 to rotate and adjust.

[0035] Furthermore, the second drive mechanism includes a second drive motor 17 disposed inside the sliding support block 15 and a connecting column 18 for connecting the second drive motor 17 and the placement rack 16. Another sliding support block 15, located away from the second drive motor 17, is rotatably connected to a second connecting column 1801 connected to the placement rack 16. The placement rack 16 has two symmetrically arranged discharge ports 19 at one end near the housing 5. When the second drive motor 17 is turned on, it drives the placement rack 16 to rotate and tilt closer to the housing 5, thereby allowing the enoki mushrooms placed on the placement rack 16 to pass through the two discharge ports 19. The material is discharged into the box 5 through the discharge port 19. Then, the box 5 containing enoki mushrooms is slid to the waiting area using the second electric slide rail 20. At this time, the side of the box 5 away from the waiting area is sealed by the second sealing plate 22 to maintain the heat inside the storage 1 and prevent cold air from escaping. After that, the staff takes it out. After taking it out, the box 5 is reset again using the second electric slide rail 20.

The two interleaved first thermal insulation sealing doors 25 and the second thermal insulation sealing door 26 can improve their sealing and insulation performance and prevent cold air from flowing out.

[0039] Furthermore, several temperature sensors 29 are dispersedly arranged inside the storage body 1. A combination lock body 30 is provided on the outer side of the second insulated sealing door 26 for users to lock and open the insulated sealing door 6. The second insulated sealing door 26 has a hidden groove for hiding the combination lock body 30 to prevent it from protruding and affecting the opening and closing of the sealing door. A temperature zone monitor 31 is installed in the hidden groove. Several temperature sensors 29 are connected to the temperature zone monitor 31 to monitor the temperature at different locations inside the storage body 1 and to promptly detect and cool down the area. Refrigeration compressors 7 extending into the storage body 1 are installed on both sides of the storage body 1. The exhaust vent of the refrigeration compressor 7 is close to the enoki mushroom placement rack 4.

[0040] The ventilation fan structure 2 includes a ventilation duct 201, a ventilation fan 202 disposed inside the ventilation duct 201, and an adjustment window structure 203 disposed inside the ventilation duct 201 and used to seal the ventilation duct 201.

The adjustment window structure 203 includes a plurality of sealing plates 8 that are rotatably connected to both sides inside the ventilation duct 201 in sequence, and a drive mechanism for driving the plurality of sealing plates 8 to rotate and adjust.

[0041] Furthermore, the drive mechanism includes a drive motor 9 mounted on the upper surface of the ventilation duct 201, a first sprocket 10 mounted on the output end of the drive motor 9, and several second sprockets 11. One end of the sealing plate 8 is provided with a rotating rod that extends through to the outside of the ventilation duct 201. Several second sprockets 11 are respectively connected to several rotating rods. Several second sprockets 11 are connected to the first sprocket 10 via a chain 13. The drive motor 9 is used to turn on and drive the first sprocket 10, and the chain 13 drives several second sprockets 11 to rotate, thereby driving several sealing plates 8 to rotate synchronously until the multiple sealing plates 8 are adjusted to seal the entire ventilation duct 201, thereby achieving heat preservation of the interior of the storage body 1, preventing cold air from being discharged, and improving the durability of low temperature.

[0042] A method for using a cooling and storage device for enoki mushrooms includes the following steps:

[0043] S1: When cooling the storage area on one side of the interior of the warehouse 1, cold air is delivered to the storage area through the refrigeration compressor 7, and the internal temperature is reduced and dehumidified by the ventilation fan structure 2 at the same time. Several temperature sensors 29 and temperature zone monitor 31 are used to monitor the internal temperature. When the required temperature is reached, the cooling is stopped.

[0044] S2: Then, the drive motor 9 will be used to activate the first sprocket 10, using the chain...

[0045] 13 drives several second sprockets 11 to rotate, thereby driving several sealing plates 8 to rotate synchronously until multiple sealing plates 8 are adjusted to seal the entire ventilation duct 201, thereby achieving heat preservation inside the warehouse 1, preventing cold air from being discharged, and improving the durability of low temperature.

[0046] S3: When it is necessary to retrieve the enoki mushrooms stored inside the storage area, the first and second insulated sealing doors 25 and 26 are slid open using the first electric telescopic rod 27 and the second electric telescopic rod 28, allowing staff to enter the waiting area. Then, the electric slide rail 14 drives the placement rack 16 to slide close to the box 5. Next, the second drive motor 17 is activated, causing the placement rack 16 to rotate and tilt closer to the box 5, thus allowing the enoki mushrooms placed on the rack 16 to slide out through the two discharge ports 19. Inside the container 5, the container 5 containing enoki mushrooms is then slid to the waiting area using the second electric slide rail 20. At this time, the side of the container 5 away from the waiting area is sealed by the second sealing plate 22 to maintain the temperature inside the storage 1 and prevent cold air from escaping. After that, the staff takes it out. After taking it out, the container 5 is reset again using the second electric slide rail 20. After resetting, the second sealing plate 22 on the side away from the enoki mushroom rack 4 will also seal the passage, thus maintaining the temperature inside the storage 1, preventing cold air from escaping, and improving the durability of the low temperature.
