Description

Novel oranges and tangerines preservation box

Technical Field

The invention relates to the field of citrus preservation, in particular to a citrus preservation box which has a long preservation effect and is convenient to transport, the low temperature of the citrus preservation box is kept for a longer time, the oxygen content is reduced, and the like, the citrus preservation time is prolonged, the better preservation effect is achieved, and the storage, the transportation and the like are convenient.

Background

At present, after the citrus is picked, fruit growers planting citrus mostly pack the citrus by using common baskets, but the citrus is placed for a short time due to the influences of temperature, moisture and the like, and the citrus is gradually rotten after being placed for a long time. For fruit growers, fruit merchants and the like, the problem of fresh-keeping of oranges is very important. Meanwhile, the fresh-keeping of the oranges is also important in the long-distance transportation of the oranges, and if the oranges are transported by boxes and baskets, certain loss can be caused in the transportation process.

Disclosure of Invention

Aiming at the problems, the invention provides a preservation box which can keep a low-temperature environment for a long time, is convenient to transport and is easy to store and preserve in order to solve the problems that the preservation box is difficult to keep the low temperature for a long time, is inconvenient to transport and rot and the like. The fresh-keeping box is convenient to assemble, the adopted materials are common, the cost is low, the requirements of people can be better met, and the fresh-keeping problem of oranges is solved.

The technical problem to be solved by the invention is realized by adopting the following technical scheme:

a novel orange fresh-keeping box is integrally composed of a drawer-type box layer and a box groove. The box groove 1 is hollow, and the inner wall and the outer wall of the box groove are made of stainless steel with better temperature conductivity. A circular opening 11 is formed in the rear portion of the tank 1, and a push-pull type gate valve is formed in the rear portion of the tank 1 in order to improve the sealing performance of the tank 1, and rubber screws 13 are inserted into the small holes 12 formed in both ends of the gate valve plate to reinforce the gate valve so as not to slide. When using the preservation box, earlier put into the ice crystal from opening 11, fill up in the box groove 1, then with its inside evacuation, so, the ice crystal melts the speed and reduces greatly for the preservation box keeps the low temperature of longer time. The bottom of the drawer-type box layer 2 is a stainless steel separation net 22, but the bottom of the drawer-type box layer 2 at the bottom is a stainless steel sheet, and one or more object placing plates 21 can be installed in each drawer according to the requirement. The object placing plate 21 is made of hard glue, a plurality of circular grooves 211 and a plurality of small holes are formed in the object placing plate, oranges placed on the object placing plate can be separated, so that each orange can well contact with cold air, and a certain gap is formed between each orange and the corresponding orange, and therefore breeding of microorganisms such as bacteria is reduced. In addition, in order to weaken the respiration of the oranges, particle packages capable of absorbing carbon dioxide and oxygen are placed on the stainless steel separation net 22 at the bottom of each drawer-type box layer 2, so that the content of oxygen and carbon dioxide in the drawer-type box layers 2 is reduced, the respiration of the oranges is slowed down, and a good fresh-keeping effect is achieved in a low-temperature environment. Meanwhile, a plastic film with poor thermal conductivity is sleeved on the outer layer of the whole preservation box, so that heat conduction with the outside is reduced, and the low temperature of the preservation box is more durable. Therefore, the buffer force of the preservation box can be increased, the preservation box is protected, low temperature can be kept better, and a better preservation effect is achieved. Therefore, the buffer force of the preservation box can be increased, the preservation box is protected, low temperature can be kept better, and a better preservation effect is achieved.

Preferably, the box groove is made of stainless steel materials, so that the box groove is more durable, wear-resistant, firm and firm.

Preferably, the opening and the gate valve are arranged, so that the tightness of the box groove is improved, and the box groove is convenient to open and close.

Preferably, rubber screws are adopted, so that the door valve is fixed conveniently and the tightness of the box groove is not influenced.

Preferably, the ice crystals are placed in the box groove and vacuumized, so that the melting speed of the ice crystals is greatly reduced under the vacuum condition, and the low temperature in the preservation box can be maintained for a longer time.

Preferably, the drawer type box layer is convenient for placing and taking oranges, a plurality of storage plates can be placed, the space in the drawer is well utilized, and the number of the oranges which can be placed is increased.

Preferably, a plurality of small holes are formed in the object placing plate, so that the circulation of air between the drawer type box layers is facilitated, and the breeding of microorganisms such as bacteria is reduced.

Preferably, oxygen and carbon dioxide are reduced, so that the respiration of the citrus is favorably slowed down, and the consumption of the citrus is reduced.

Preferably, the foam box is additionally arranged outside the preservation box, so that the low-temperature environment of the preservation box is better maintained.

Detailed Description

When the preservation box is used, ice crystals are placed into the box groove 1 from the opening 11, then the box groove 1 is vacuumized, the push-pull valve is closed, and the ice crystals are fixed through the small holes 12 and the rubber screws 13, and meanwhile, the airtightness of the box groove 1 is guaranteed. Under the vacuum state, the ice crystal melting speed is greatly reduced, so that the low temperature is kept for a long time, and the fresh-keeping of the oranges is facilitated. Can install as required in the drawer type box layer 2 and put thing board 21, put and have many recesses 211 on the thing board 21 for there is certain spatial distance between oranges and tangerines, thereby is difficult for letting microorganism such as bacterium breed. A plurality of small holes are formed around the groove 211, so that each drawer type box layer 2 is communicated with the surrounding environment uniformly, in addition, in order to reduce the respiration of the oranges, the oxygen and carbon dioxide content in the preservation box is reduced by utilizing particle packages capable of absorbing oxygen and carbon dioxide, and a plastic film with poor heat conductivity is sleeved on the outer layer of the whole preservation box, so that the heat conduction with the outside is reduced, and the low temperature of the preservation box is more durable.
