Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dough-shaped refrigeration device, and provides a compact, large-sized sterile constant-temperature refrigeration device that is easy to manage.

BACKGROUND ART Temperature refrigerators, which are stored at a low temperature of 1 to 5° C., have traditionally been used to store fresh foods, biochemical preparations, pharmaceuticals, and other items that do not like freezing.

Most warehouses of this type are rectangular in shape, and if they are large, the temperature distribution inside the warehouse will not be uniform, and as a result of using the immediate cooling method, there is a high risk of freezing.
It is also well known that cooling tends to dry the air inside the warehouse, causing the outside of stored items to dry out or turn brown. The inventor of the present invention has conducted research to develop a sterile constant-temperature refrigeration system that eliminates the drawbacks of conventional low-temperature storage warehouses, keeps the interior of the warehouse always clean, prevents stored items from drying or freezing, and has extremely small temperature changes. As a result, a cold storage room was constructed between the outer cylinder and the inner cylinder, and a cold water mist cyclone surrounded by a cold water tank was housed in the hollow part of the inner cylinder. We were able to create a sterile constant-temperature refrigeration system by arranging suitable shelves, circulating the gas in the refrigeration room through a cold water lamp cyclone, and cooling the room with moisture-saturated gas.

To explain the present invention with the drawings, 1 is an outer cylinder of the refrigerator, 2 is an inner cylinder, and a refrigerator compartment A is constructed between them.

Therefore, the refrigerator compartment A has a donut shape. A ventilation distribution plate 3 is fixed to the wall surfaces of the outer cylinder 1 and the inner cylinder 2 at a certain interval, and the ventilation distribution plate 3 is a porous plate such as a wire mesh or a punched wire mesh, and is used for gas circulation. is possible. Further, organic or inorganic heat insulating materials 18, 18, such as glass wool, foamed resin, or cinnabar algae, are attached to the outside of the outer cylinder 1 and the inner cylinder 2 to block heat transfer from the outside world. 4 is the bottom part of the refrigerator, and 5 is the top part. The bottom part 4 is made of iron plate, concrete, or other hard material, and it is preferable to fill the bottom part with a heat insulating material.

The upper part 5 is made of the same material as the outer cylinder 1, and the heat insulating material 1 is placed on the outside thereof.
Attach 8. Reference numeral 6 is a shelf provided in the room A, and there are usually many partitioned shelves 6, 6...
... is configured in a donut shape, and the lowest floor plate 1 of this shelf 6
9 has a wheel 7 on its lower side near the outer cylinder 1 and inner cylinder 2.
, 7 are attached so that they can rotate on the bottom 4 of the refrigerator around the inner cylinder 2.

Reference numeral 8 denotes a motor for driving a logical body attached near the outer cylinder 1, which rotates and stops in response to commands from the outside. A cold water tank 10 is provided in the hollow part 20 of the inner cylinder 2 to constantly store cold water necessary for cooling, and a first cyclone 9 is fixed inside the tank 10, and a water pipe 22 is provided outside the tank 10. The water is flooded into the first cyclone 9 via the pump 13 and the water pipe 22'.

Inside the first cyclone 9, there are a number of nozzles 2 in the water pipe 22'.
3 is installed to spray water in the form of mist. Further, a water take-out pipe 24 is closed at the lower end of the first cyclone 9, and is passed through a cooler 14, where it is cooled to a constant low temperature, for example, 0 to 3°C. The cooled water is transferred to the cold water tank 1 via the pipe 24'.
Return 01. Although not shown in the figure, it is convenient to have a pipe pass through the water intake port of the cold water tank 10 and the cooler 14, and to make it possible to switch between the water intake pipe 24 and the water intake pipe 24 by operating a valve. Reference numeral 25 denotes a filter provided on the pipe 24, into which water flows in from one side and flows out from the other side.

The inside of the furnace 25 is filled with adsorbents such as powdered or granular activated carbon, bone charcoal, ion exchange resin, etc., and when water passes through it, suspended matter, solid matter, and dissolved impurities contained therein are removed. Pass through an adsorption furnace. For this reason, the furnace has a structure that allows easy loading and unloading of these adsorbents. Reference numeral 15 denotes an air intake duct, which communicates with the lower part of the ventilation distribution plate 3 provided on the inner cylinder 2 side of the chamber A, supplies air with the fan 12, and passes through the air pipe 26.
The gas in the chamber A is blown toward the first cyclone 9.

For this reason, in the first cyclone 9, the gas comes into contact with the above-mentioned false mist-like cold water and is rapidly cooled, and the steam becomes saturated at that temperature, and due to the effect of the mist droplets, the dust in the gas and various bacteria and spores floating with this dust are generated. is adsorbed and removed by the centrifugal effect, resulting in a clean gas that has been dedusted and sterilized and is discharged from the air pipe 27. Reference numeral 11 denotes a second cyclone, which has the other end of the air pipe 27 open so as to suck in gas from the direction of the cutting line.

Therefore, residual water droplets accompanying the gas are completely removed. The purified gas is pushed by the back pressure from the fan 12 and enters the air duct 16 through the air pipe 28. Since the air supply duct communicates with the lower part of the ventilation distribution plate 3 provided close to the outer cylinder 1, the gas flows into the chamber A on average due to the mesh effect of the distribution plate 3. Note that 17 is outer cylinder 1
This is the storage goods loading and unloading port provided in the
is equipped with air shutters, etc., which are normally attached to low-temperature warehouses, to prevent cooling gas from escaping to the outside even when the door is opened. The apparatus of the present invention is constructed as described above, and during operation, the cooler 14, the pump 1
3 to circulate the water in the cold water tank 10 and cool it to a predetermined temperature, for example 1 to 200.

Next, the fan 12 is driven to draw air from the intake duct 15 and send it into the first cyclone 9. Here, as mentioned above, dust and bacteria are removed by the mist droplet effect and centrifugal effect, and the gas is instantly cooled to become a gas with constant temperature and humidity. At this time, undesirable bad odors in the gas, such as ammonia odor, fermentation odor such as sulfide odor, and other bad odors originating from stored materials, are easily dissolved in the water and flowed down to the lower part of the first cyclone 9. This water flows into the furnace 25 below, where it is adsorbed and purified by contact with the adsorbent, cooled by the cooler 14, and returned to the cold water tank 10. Further, the purified gas is further purified by the second cyclone, completely removing dust and bacteria, and becoming a gas with constant temperature and humidity, which passes through the air supply duct 16 and the ventilation distribution plate 3 on the side of the outer cylinder 1. and flows into chamber A. Therefore, in room A, clean, constant temperature and humidity gas always flows from the outer cylinder 1 side to the inner cylinder 2 side, so the temperature in room A is always kept constant and the stored items are kept constant. It will be refrigerated without drying due to moisture. The shelf 6 can also be constantly rotated, thereby completely eliminating uneven cooling. To take in and take out stored items in room A, use entrance 17.
Therefore, the shelf 6 to be stored is
Rotate the motor 8 to align it with the inlet/outlet 17.
Next, the air shutter is operated to open the loading/unloading port 17 to store the stored items. This operation is repeated to store the stored items in the room A. When unloading the stored items, the shelf of the stored items to be unloaded is aligned with the loading/unloading port 17 and the stored items are taken out. Therefore, if the imported items are stored in the computer and the computer and motor 8 are operated,
Items can be reliably taken out by pressing a button, and even if a large refrigeration system is counterfeited, it can be managed extremely easily. Therefore, even if many types of items are stored at the same time, there will be no confusion in loading and unloading them. The present invention is constructed as described above, and can also be used as a large-scale refrigeration system by reducing the heat dissipation area by making it a circular warehouse, and by constantly circulating dust-removed and sterilized gas in room A to maintain cleanliness. Since the cold water for cooling is always stored in the cold water tank 10, it is possible to respond to load fluctuations by simply adjusting the fan 12.
Since the cold water is atomized, there is little temperature difference between the cooling water and the gas, and the cooler can also be small.

Furthermore, since a rotating shelf is provided in the room A, it is convenient to take things in and out, making it easy to manage the refrigeration equipment. The device of the present invention can be used for items that do not like freezing or drying, such as vegetables.
It is effective when used to store meat, biochemical substances, chemicals, chocolate, and other confectionery.
