Abstract

The utility model relates to a preserving tank for fruit or vegetables, which is composed of a freezing water inlet pipe, an annular cold pipe, a vacuum vegetable storing tank, a ribbed plate, a freezing water returning pipe, a sealing door and an observation hole, and the utility model is a specific container for preserving fruit or vegetables. The utility model can defer the senescence of the fruit or the vegetables through controlling the physiological change of the picked plant, such as the fruit or the vegetables, etc., in the specific container, and can coordinate temperature and humidity required by the fruit or the vegetables and reduce the infectious diseases of the fruit or the vegetables; after the fruit or the vegetables are moved into the normal air, the afterripening is also slow so that the fruit or the vegetables have long life on shelves; the utility model can be widely applied to preserving the fruit or the vegetables.

Description

Preservation tank for fruit or vegetables

The utility model relates to a kind of storage tank that is used for preserving fruit and vegetable utilizing, belongs to the preservation of the fruits and vegetables in human lives field.

At present, the vegetable fresh-keeping processing technology that is adopted is a controlled atmosphere, is called for short the CA storage, and the principal mode of CA storage is to utilize mechanically refrigerated airtight storehouse, and is equipped with other control device, makes the certain low temperature of maintenance in the storehouse, hypoxemia, suitable CO ₂And temperature, and in time get rid of pernicious gas in the storehouse, thus reduce the respiratory rate of fruits and vegetables, reach the purpose that postpones after-ripening, preservation and freshness.The U.S. manufactured experimently out a kind of burning nitrogen (N in 1962 ₂) generating means, be fuel with propane, the oxygen (O in the combustion air ₂) obtain nitrogen (N ₂), can make air conditioned storage fall O ₂, it is to utilize mechanical device to fall oxygen rapidly and keep gas composition in the air-conditioned cold store.1978, China built up first experimental simulation air-conditioned cold store.In recent years, the silicone rubber membrane of Chinese Academy of Sciences's research is applied in the air conditioned storage.More than these conventional transfer storage, though obtained good effect, significant disadvantages is arranged also, for example: increased the weight of the disorder of fruits and vegetables, produced the after-ripening inequality, lost its relish and fragrance by test.

And the decompression air conditioned storage is the physilogical characteristics after gathering according to different fruits and vegetables, utilizes sequence of operations such as decompression, vacuum to control the after-ripening process of fruits and vegetables.It is the development of air conditioned storage, is a kind of special air conditioned storage mode, and total air pressure reduces, O ₂The also corresponding reduction of dividing potential drop, and can be than the more accurate O of CA storage control ₂It is accurate that level, relative humiture are also controlled.

The purpose of this utility model overcomes weak point of the prior art exactly, adopts decompression air conditioned storage mode to delay or suppresses aging, the ageing process of fruits and vegetables, the coordination required humiture of fruits and vegetables and a kind of fruit and vegetable fresh preservation jar of providing.

The purpose of this utility model realizes by following measure:

This storage tank is made up of freezing water intaking pipe ［ 1 ］, annular cold pipe ［ 2 ］, vacuum vegetable storage jar ［ 3 ］, floor ［ 4 ］, freezing water returning pipe ［ 5 ］, hermatic door ［ 6 ］ and peep hole ［ 7 ］; The cross section of vacuum vegetable storage jar ［ 3 ］ is circular, on the interior wall of vacuum vegetable storage jar ［ 3 ］, have along the circumferential direction and weld the annular cold pipe of making ［ 2 ］ every 40cm～100cm, freezing water intaking pipe ［ 1 ］ is positioned at the outer wall top of vacuum vegetable storage jar ［ 3 ］, and each tube connector ［ 8 ］ is connected with its welding and with inwall on the annular cold pipe ［ 2 ］ that is provided with connect; Be welded with the floor ［ 4 ］ of " ten " font or " rice " font along the inner ring of annular cold pipe ［ 3 ］, the pipe of the cross direction of floor communicates with annular cold pipe ［ 2 ］.

Floor of the present utility model ［ 4 ］ is to be made by the welded tube of φ 50mm～φ 76mm, and the material of annular cold pipe ［ 2 ］ is the I8 channel-section steel, along the circumferential direction is welded on the inwall of vacuum vegetable storage jar ［ 3 ］ or adopts the seamless steel pipe of φ 32mm～φ 76mm.

The drawing explanation of accompanying drawing:

Fig. 1 is the external form schematic diagram of fresh-retaining preserving jar;

Fig. 2 is the longitudinal section of fresh-retaining preserving jar;

Fig. 3 is the structural representation of rice font floor;

Below in conjunction with drawings and Examples the utility model is further described:

The material that the vacuum vegetable storage jar ［ 3 ］ of embodiment adopts is a YB234---63 tubing, and wall thickness is 4mm, and length 17.8m, cross-sectional diameter are 4m; Treated chilled water enters along diameter in the cross pipe of the annular cold pipe ［ 2 ］ of 1m and floor by tube connector ［ 8 ］ water along chilled water pipe ［ 1 ］, after enter the freezing water returning pipe ［ 5 ］ of vegetable storage jar ［ 3 ］ bottom, through drawing water chilled water is extracted out outside the jar, constantly repeated just can reduce a jar interior temperature with this with water pump.The material of the cold pipe of annular ［ 2 ］ is the I8 channel-section steel, it is to be welded on the inwall of vacuum vegetable storage jar ［ 3 ］, each annular cold pipe ［ 2 ］ is welded with the floor of one " rice " font again, the pipe of cross direction is connected mutually and is communicated with cold pipe of annular and freezing water returning pipe ［ 5 ］, promptly work to support the dish jar, reduce jar in a temperature can be used as the shelf effect of supporting again, strengthen a jar interior storage dish amount, floor is to be made by the welded tube of φ 50mm.

Adopt this special container that the physiological change of fruits and vegetables is controlled and to postpone the fruits and vegetables aging, and can coordinate the required humiture of fruits and vegetables, alleviate the infectious disease of fruits and vegetables, at the fruits and vegetables of storage tank by refrigeration, move into normal air, after-ripening is still slower, and long shelf life is arranged.
