Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems of the existing integrated controlled atmosphere storage, such as the open and close storage door, which has a great influence on the environmental factors in the storage, the high turnover cost of fruits and vegetables, and the large investment cost, etc., and provide a small temperature difference refrigeration and moisturizing storage controlled atmosphere Warehouses, adopting segmental stacking technology to separate the air-conditioned warehouses to form relatively independent "small warehouses", which reduces the temperature fluctuations in different stacks, and when the door is opened and closed, the temperature difference and humidity in the unopened stacks Less affected

Embodiment 1

[0017] A controlled-atmosphere warehouse for cooling and moisturizing storage with small temperature differences in sections, suitable for large-scale storage capacity of more than 1,000 tons. In this embodiment, 12.5 tons of vegetables are stored in each stack, and a total of 1,250 tons is stored. The vegetables described are celery. The specific steps are as follows :

[0018] 1) Establish storage stacks: According to the size of the controlled atmosphere storage, divide the controlled atmosphere storage into small sections with a length of 5m and a width of 4m, and set up a ventilation line 10cm above the ground to form a relatively independent storage stack. After laying the sleepers to raise the height, lay a polyethylene film with a thickness of 0.16mm on the sleepers;

[0019] 2) Palletizing storage: Palletizing and storing the celery packed in baskets. Palletizing requires a gap of 25-30cm between the stack and the wall, and between the stack and the stack. The distan...

Embodiment 2

[0022] A controlled-atmosphere warehouse for cooling and moisturizing storage with small temperature differences in sections, which is suitable for large storage capacity of more than 1,000 tons. In this embodiment, 15 tons of apples are stored in each stack, and a total of 1,500 tons is stored. The specific steps are as follows:

[0023] 1) Establish storage stacks: According to the size of the controlled atmosphere storage, divide the controlled atmosphere storage into small sections with a length of 5m and a width of 4.5m, and set up ventilation lines 15cm above the ground to form relatively independent storage stacks. After laying the sleepers at the bottom, lay a polyethylene film with a thickness of 0.16mm on the sleepers;

[0024] 2) Palletizing storage: Palletizing and storing the boxed apples. Palletizing requires a gap of 25-30cm between the stack and the wall, and between the stack and the stack. The distance between the openings is ≥1.5m to facilitate ventilation. ...

Embodiment 3

[0027] A controlled-atmosphere storehouse for cooling and moisturizing storage with small temperature differences in sections, suitable for large storage capacity of more than 1,000 tons. In this embodiment, 12 tons of jujubes are stored in each stack, and a total of 1,200 tons is stored. The specific steps are as follows:

[0028] 1) Establish storage stacks: According to the size of the controlled atmosphere storage, divide the controlled atmosphere storage into small sections with a length of 5m and a width of 5m, and set up ventilation rows 10-20cm above the ground to form relatively independent storage stacks. After laying the sleepers at the bottom of the stack, lay a polyethylene film with a thickness of 0.16mm on the sleepers;

[0029] 2) Palletizing storage: Palletize and store the jujubes in baskets. Palletizing requires a gap of 25-30cm between the stack and the wall, and between the stack and the stack. Vent spacing ≥ 1.5m to facilitate ventilation. When stacking,...

Abstract

The present invention discloses a segmented refrigerating and moisturizing air conditioned storehouse with a small temperature difference. The segmented air conditioned storehouse is suitable for air conditioned storage with a large capacity of 1,000 tons or more. The air conditioned storehouse is characterized by: dividing the storehouse into segments with a length of 5 m and a width of 4 to 5 m according to the capacity of the air conditioned storehouse, and setting up a ventilation line 10 to 20 cm off the ground to form a relatively independent storage stack; laying crossties in the bottom of the storage stack, spreading a polyethylene film in 0.16 mm thickness on the crossties, and thereby storing the basket-packaged or case-packaged fruits and vegetables into stacks; and then spreading polyethylene films in 0.16 mm thickness from all sides of the top of the stacks to the bottom of the stocks, then rolling up the bottom polyethylene films, tying the bottom polyethylene films tightly with the top polyethylene films and sealing the stack bodies closely; adjusting the internal gas, temperature and humidity of each stock to meet the requirements for fruit and vegetable storage. The invention segments the air conditioned storehouse into a number of small storehouses, and thus stacks can be removed out of the storehouse separately due to relative independence between the stacks. The invention also reduces temperature fluctuations in different stacks and temperature differences between different stack locations when fruits and vegetables are moved out of the storehouse. The segmented storehouse has a good preservation of heat and moisture, and a regulation of oxygen, carbon dioxide, nitrogen and other effective gas.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable storage and fresh-keeping, and in particular relates to a cold-humidity storage with small temperature difference in compartments and a controlled-atmosphere storage. Background technique [0002] Controlled atmosphere storage, also known as controlled atmosphere storage, is a new technology for storing fresh fruits and vegetables that has emerged in recent years. It is based on cold storage, adding gas components (such as carbon dioxide, nitrogen, etc.) to adjust, and by controlling the temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment, it can inhibit the respiration of fruits and vegetables and delay their metabolic process. , to better maintain the freshness and commerciality of fruits and vegetables, and to extend the storage and preservation period of fruits and vegetables. According to experiments, controlled atmosp...
