Problems solved by technology

[0003] Modified atmosphere preservation, as the name suggests, is to use the method of controlling the gas ratio to achieve the purpose of storage and preservation. The modified atmosphere preservation technology is a technology that prolongs the storage life and shelf life of food by adjusting the ambient gas. The method is to carry out the fresh-keeping operation by covering the storage chamber with inert gas. However, in the actual long-term storage process, it is still necessary to regularly re-ventilate inward to keep fresh. However, the ventilation effect is often poor, and a large amount of long-term ventilation is required. Will affect the actual preservation effect of agricultural products

Embodiment 1

[0031] refer to Figure 1-Figure 2 , an air-conditioning fresh-keeping device for agricultural products, comprising a storage box 1, both ends of the storage box 1 can be detachably connected with a box cover 101, the interior of the storage box 1 is provided with a fixed cavity of a cylindrical structure, and the circumferential inner wall of the fixed cavity rotates A horizontally placed storage cylinder 2 is connected, a ventilated partition mechanism is fixed between the top and bottom of the storage cylinder 2, the partition mechanism is driven and connected with a drive motor 25, and the circumferential inner wall of the storage cylinder 2 is provided with staggered connection grooves to connect The groove is communicated with the air cavity of the separation mechanism. In actual use, the agricultural products are placed in the chamber separated by the separation mechanism in the storage cylinder 2, the box cover 101 is closed, and then inert gas is introduced from the se...

Embodiment 2

[0037] Example 2 includes all the structures and methods of Example 1, refer to figure 2 and Image 6 , an air-conditioning fresh-keeping device for agricultural products, further comprising: an outer wall of one end of the storage box 1 is located at the periphery of the storage cylinder 2 and is provided with a circularly distributed ventilation cavity 10; A ring-shaped communication groove 16 is opened at the position corresponding to the outer circumferential wall and the second connection groove 9 , a connection hole 17 is opened between the communication groove 16 and the second connection groove 9 , and the inner wall of the ventilation cavity 10 is opened at the position corresponding to the communication groove 16 There is a through groove 18. In actual use, when the protective gas is introduced into the ventilation pipe 4, the protective gas flows from the ventilation cavity at the same time, and the communication groove 16 of the storage cylinder 2 and its outer wa...

Embodiment 3

[0042] Example 3 includes all structures and methods of Example 1 and Example 2, refer to Figure 11-Figure 12 , an air-conditioning fresh-keeping device for agricultural products, further comprising: a drive motor 25 is fixed on the inner wall of one end of the storage box 1; The inner wall is located on both sides of the partition plate 3 and is slidably connected with baffles 11 , the outer wall of the baffle 11 is fixed with a limit block 1101 that is slidably connected with the limit slot 7 , and an arc-shaped end of the baffle 11 close to the drive motor 25 is fixed. The limit ring 26 of the structure, the two limit rings 26 form a circular ring with a gap in the middle position, and the end of the limit ring 26 away from the baffle 11 is provided with an arc-shaped positioning groove 27. The arc angle of the positioning groove 27 More than one hundred and eighty degrees, both sides of the inner wall of one end of the storage box 1 are fixed with a horizontally extending...

Abstract

The invention belongs to the technical field of agricultural products, and particularly relates to an agricultural product modified atmosphere fresh-keeping device which is characterized in that the agricultural product modified atmosphere fresh-keeping device comprises a storage box, a fixing cavity of a cylindrical structure is formed in the storage box, and the circumferential inner wall of the fixing cavity is rotationally connected with a horizontally-placed storage barrel; a ventilating separation mechanism is fixed between the top and the bottom of the storage barrel, the separation mechanism is in transmission connection with a driving motor, connecting grooves which are distributed in a staggered mode are formed in the circumferential inner wall of the storage barrel, and the connecting grooves communicate with an air cavity of the separation mechanism. The connecting grooves which are distributed in the storage barrel in a staggered mode and communicate with the separation mechanism are matched with rotation of the storage barrel to enable airflow to be dispersed to all positions on the periphery of the storage barrel along the connecting grooves, the introduced airflow and agricultural products move relatively, and therefore the airflow can be rapidly and effectively filled in a short time to conduct fresh-keeping operation.

Description

technical field [0001] The invention relates to the technical field of agricultural products, in particular to an air-conditioned fresh-keeping device for agricultural products. Background technique [0002] Agricultural product processing is a production activity that uses physical, chemical and biological methods to make the main and by-products of agriculture into various foods or other supplies. It is an important link for agricultural products from the production field to the consumption field. Use modified atmosphere for freshness. [0003] Modified atmosphere preservation, as the name suggests, uses the method of controlling the proportion of gas to achieve the purpose of storage and preservation. The modified atmosphere preservation technology is a technology that prolongs the storage life and shelf life of food by adjusting the ambient gas. The method is to carry out the fresh-keeping operation by covering the storage chamber with inert gas. However, during the lon...
