Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a cylindrical cold storage for storing agricultural products and other perishable products.

[Subject skill]

When storing fruits and vegetables such as vegetables and fruits, it is known that lowering the concentration of 0□ in the storage atmosphere is effective in extending the shelf life.
□C A (
Controlled Atomosphere) storage, etc. are used.

In such storages, items larger than 0.5 tsubo are generally rectangular warehouses with entrances and exits for people, and when storing them inside and taking them out to the outside, people or their substitutes cannot enter and exit. They take in and take out stored items.

[Problems to be solved by this invention] However, the inside of the storage room has a high CO8 concentration and low 0□ concentration atmosphere due to the introduction of CO and gas, and the respiration of the stored items themselves, and it is difficult for people to enter the storage room. In some cases, it is necessary to enter the room after the internal atmosphere has been replaced with air that is safe for humans, and it takes time to enter and exit, the internal atmosphere disappears, energy is wasted due to recovery, and there is danger. There is a problem with this.

Furthermore, although the above-mentioned problem can be solved by using an unmanned automatic device instead of a human, the device becomes complicated and expensive. moreover,
A space for people to enter is required, and the inside of the refrigerator cannot be used effectively.

This invention was made to solve the above-mentioned problems, and its purpose is to enable storage and removal of stored items from outside the warehouse without entering the warehouse, which is advantageous in terms of safety and energy consumption. Another object of the present invention is to provide a cylindrical low-temperature storage that can effectively utilize the inside of the storage.

[Means to solve the problem]

In the present invention, as shown in FIGS. 1 and 2, the storage is a cylindrical sealed container 1, and within this cylindrical sealed container, a column 2 is rotatable about the central axis C of the container. A plurality of shelves 4 capable of storing containers 3 are attached to this support 2 at intervals in the direction of the central axis C, and a take-out port 5 parallel to the central axis C is provided in the side wall IA of the cylindrical sealed container 1. A closing door 6 is provided.

The shelf 4 may be a ring-shaped disc with air permeability, or the shelf 4 may have arms supporting the container 3 radially protruding from the support 2. Moreover, the containers 3 may be stacked on one shelf 4 in one level or in multiple levels.

The support column 3 is preferably hollow with both ends open, and the cooling device 7 is preferably provided in the cylindrical sealed container 1 at the upper part of the hollow support column 3. Further, it is preferable that the container 3 has a sector-shaped planar shape.

[For production]

By simply opening the opening/closing door 6, stored items can be taken in and out from outside the storage via the single access port 5, eliminating the need for humans to enter the storage as in the past, reducing high CO2 inside the storage! , there is no danger of breathing low 08 air.

Once loading and unloading of containers in a row in the direction of central axis C is completed,
The column 3, that is, the shelf 4 is rotated by a predetermined angle around the central axis C, and the new part is brought to the entrance 5. By repeating this, the containers 3 are loaded and unloaded. Note that the support columns 2 may be rotated manually by directly holding the shelves 4 by hand.
A rotation drive device may be connected and the rotation may be automatically rotated by a predetermined angle using a push button switch or the like. Since the shelves 4 are rotated and taken in and out from a single take-out/outlet 5 without entering the warehouse as in the conventional case, the time taken to take in and take out the warehouse can be shortened. In addition, since the time required to enter and exit the warehouse is short and there is no need to actively eliminate the atmosphere inside the warehouse, there is little energy loss.

In addition, in order to prevent the atmosphere inside the refrigerator from being washed away as much as possible when loading and unloading, as shown in FIG. It is also possible to seal the shelf with a sealing member 9 so that only a part of the shelf is exposed to the atmosphere. This is an effective function when you want to take out only a part of the stored items.

Regarding cooling, since the container 1 is cylindrical, the flow of cold air inside the refrigerator is more uniform than in a typical square refrigerator, which is advantageous for preserving food. Furthermore, as shown in FIG.
Since the water circulates in the form of a duct, the flow is uniformly rectified across the cross section of the container, promoting uniformity of the atmosphere inside the refrigerator.

If the container 3 is fan-shaped, it can be stored more closely in the circumferential direction than a rectangular shape, and more items can be stored with the same volume.

〔Example〕

This is an example of a CA refrigerated warehouse equipped with CO, gas cylinders 11, and a console 12 for control, and the warehouse is an insulated cylindrical sealed container 1 with an outer diameter of about 2 m and a height of about 3 m.

The support column 2 is a circular pipe, and support members 13 are attached to both upper and lower ends, and the support members 13 are supported by bearings 14 and 15 so as to be rotatable. The shelf 4 is a ring-shaped disc and has four levels in the vertical direction, so that the containers 3 can be stored in two levels. The container 3 is fan-shaped and can be stored in a petal-like manner on a shelf 4.

The supply chamber 10 is formed by a perforated plate 16 in the upper part of the container 1, and the cooling fan unit 7 is installed in the supply chamber 10 above the support column 2. This cooling fan unit 7 is of a type that sucks in air from below and discharges air to the sides.

The take-out/take-out entrance 5 is an opening having a width that allows the fan-shaped containers 3 to be taken in and taken out, and a height that allows a row of containers 3 in the vertical direction to be taken in and out, and an opening/closing door 6 is attached through the protrusion part IB. Needless to say, a sealing member is provided on the doorstop of the opening/closing door 6.

Fig. 6 shows an example of preventing the atmosphere inside the refrigerator from flowing out when loading and unloading the container.In correspondence with the shape of the fan-shaped container 3, partition plates 8 are arranged radially in a vertical direction, and a pair of partition plates 8 are arranged radially. Seal members 9 are disposed on both sides of the entrance 5 and brought into contact with the end face of the partition plate 8, so that only the shelf 4 at the entrance is exposed to the atmosphere.

Note that there are cross-shaped reinforcing ribs 1 on the top and bottom surfaces of the container 1.
7 to reinforce the container.

The above has explained the CA storage, but the reduced pressure storage,
It goes without saying that the present invention can be applied to other refrigerated warehouses and storage warehouses that maintain a special atmosphere inside.

〔Effect of the invention〕

As mentioned above, the low-temperature storage according to the present invention uses a cylindrical sealed container as a warehouse, and a shelf is provided on a support that can be rotated around the central axis of the container, and stored items are removed from a single access port while rotating the shelf. The following effects can be achieved by taking in and out.

(i) Stored items can be taken in and out from outside the storage, allowing for high CO2 and low CO2 inside the storage. There is no risk of breathing air.

(!i) Since the shelves can be rotated and taken in and taken out from one place without entering the warehouse as in the past, the time taken to take in and out of the warehouse can be shortened. In addition, since the time required to enter and exit the warehouse is short and there is no need to actively eliminate the atmosphere inside the warehouse, there is little energy loss.

(iii) Since it is a cylindrical container, it can be cooled more uniformly than a conventional square container, and the cooling air circulated by the hollow support and the cooling device installed on the top of the container allows for more uniform cooling. It is possible to promote uniformity of the internal atmosphere, which is advantageous in preserving freshness.

(iv) There is no need to provide an entry space inside the storage, and the cylindrical container and the fan-shaped container allow effective use of the inside of the storage.
