Problems solved by technology

However, the water source used in this method has its own problems. It usually carries a large number of plant pathogenic microorganisms and eggs to accelerate the spoilage process of fruits and vegetables. At the same time, it requires certain mechanical input and long-term continuous manual input. It is unnatural, the transpiration and evaporation of water are fast, and the water supply is unbalanced in time and space, resulting in intermittent water shortages in fruits and vegetables. Therefore, the fresh-keeping effect is severely restricted, and the decline in product quality is greatly accelerated. The fresh-keeping storage period is greatly shortened, which brings serious constraints to its seasonal adjustment, long-distance transportation, and marketing.
[0009] At present, there are also underground cellars for storing sweet potatoes, but compared with fruits and vegetables, due to the different epidermal tissue structure, fruits and vegetables are not easy to self-moisture, and the requirements for moisturizing conditions are more stringent. Therefore, fruits and vegetables cannot be stored in soil for storing sweet potatoes. cellar

Embodiment 1

[0054] like figure 1 As shown, an energy-saving and environment-friendly natural fresh-keeping storehouse for fruits and vegetables. An underground space is excavated at a depth of 3-15 meters from the ground as a storage space 1 for fruits and vegetables. The bottom surface 6 is a horizontal plane, and the fruit and vegetable storage space 1 is provided with a fruit and vegetable storage device 2 , a cooling water collection well 3 and a cooling water recovery well 4 .

[0055] The cooling water collection well 3 is used to collect underground water sources to supply water required for fresh-keeping storage. Because the groundwater source is located at a certain depth below the surface, generally speaking, it is 40-50 meters deep. The ambient temperature at this depth is low, which not only makes the water temperature low, but also contains minerals with a bactericidal effect in the water, and the relatively dense underground substances are harmful to bacteria, fungi, Large ...

Embodiment 2

[0058] like figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the bottom surface 6 of the fruit and vegetable storage space 1 is a slope with a slope of 1°-15°. The cooling water collection well 3 is arranged at the highest point of the inclined bottom surface 6 of the fruit and vegetable storage space 1, and the cooling water recovery well 4 is arranged at the lowest point.

[0059] This structure is beneficial to the automatic recovery of the waste water on the bottom surface 6 of the fruit and vegetable storage space 1, and the waste water flows into the cooling water recovery well 4 at the low point from the high point of the slope automatically without manual assistance.

Embodiment 3

[0061] like image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the bottom surface 6 of the fruit and vegetable storage space 1 is uniformly provided with cooling grooves 7 at intervals of 1-5 meters, the groove depth is 0.01-0.1 meters, and the groove width is 0.03-0.1 meters. The storage device 2 is arranged on the heat sink 7 . Around the bottom surface 6 of the fruit and vegetable storage space 1 is provided a drainage ditch 11 communicating with the cooling tank 7 , the cooling water collection well 3 and the cooling water recovery well 4 . Other structures of this embodiment are the same as those of Embodiment 1.

[0062] The design of the heat sink 7 is more conducive to the heat dissipation of fruits and vegetables, and collects waste water, and after the waste water is led into the drainage ditch 11, it finally flows into the cooling water recovery well 4. This structure makes the water on the bottom surface 6 of the fru...

Abstract

The invention discloses an energy-saving and environment-friendly natural fresh-keeping storehouse for fruits and vegetables. The fresh-keeping storehouse comprises a fruit and vegetable storage space 3-15 m from the ground surface; and the fruit and vegetable storage space is provided with a fruit and vegetable storage device, a cooling water collecting well and a cooling water recovery well. The fresh-keeping storehouse provided by the invention achieves low temperature, natural constant temperature, natural moisturizing and natural antibacterial effect with no or little rely on mechanical equipment, facilities and industrial energy, improves the storage quality of fruits and vegetables, prolongs the fresh-keeping storage period and is conducive to seasonal, spatial off-season and busy season surplus and deficiency regulation and marketing of fruits and vegetables.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping and storage of fruits and vegetables, in particular to a fresh-keeping storehouse for fresh-keeping and storing of fruits and vegetables. Background technique [0002] At present, there are generally two storage methods for fruit and vegetable products, one is to store them in cold storage for refrigeration and preservation, and the other is to store them directly indoors at room temperature. [0003] If the way of cold storage is adopted, the expense is huge and the cost is too high. [0004] However, if stored indoors at room temperature, fruits and vegetables will quickly dehydrate, even rot and deteriorate, and will no longer be fresh. [0005] This is because when fruits and vegetables are harvested, they already carry a certain amount of bacteria, fungi and other microorganisms and pests. After the fruits and vegetables leave the mother body and the reproductive system, these microor...
