Cold area cold energy fruit and vegetable fresh-keeping storehouse

Abstract

The invention discloses a cold area cold energy fruit and vegetable fresh-keeping storehouse and relates to a fruit and vegetable fresh-keeping technology by taking natural cold area cold energy as a main energy source, and is in particular suitable for a range of northern latitude 46 degrees to northern latitude 55 degrees. The cold area cold energy fruit and vegetable fresh-keeping storehouse solves the problems that an existing fruit and vegetable fresh-keeping storehouse is large in energy consumption, natural energy sources cannot be fully utilized, the fruit and vegetable storage quality is unstable, and the storage variety is single. According to the technical scheme, the fruit and vegetable fresh-keeping storehouse comprises a storehouse body, a sealed door, a channel for output and input of warehouse, a plurality of storerooms, a water pond, a drain pump and a gas regulating system. The storehouse body is arranged underground, the upper surface of the storehouse body is 1.5-2.5m from the ground, the upper surface of the storehouse body is filled with rammed earth to be aligned with the ground, the channel for output and input of warehouse is connected to the sealed door opened in the side wall of the lower end of the storehouse body in an inclined manner downward from the ground, the gas regulating system is arranged on the upper portion of the storehouse body and extends to the ground surface, the storerooms are arranged in the storehouse body, the gas regulating system of the storerooms are arranged on the top end of the storehouse body, the water pond is arranged in the bottom of the storehouse body, and the drain pump is arranged in the pond. The cold area cold energy fruit and vegetable fresh-keeping storehouse is mainly used for long-term fresh-keeping and storage of fruits and vegetables.

Description

technical field [0001] The invention relates to a fresh-keeping technology for fruits and vegetables using natural cold energy as a main energy source, and is particularly applicable to a range between 46 degrees north latitude and 55 degrees north latitude. technical background [0002] The scientific definition of Natural Cool Energy: "In the normal temperature environment, the low-temperature difference and low-temperature thermal energy that naturally exists", referred to as "cold energy". Within the range of 46 degrees north latitude to 55 degrees north latitude in northern my country, the annual ice and snow cover lasts for more than half a year, and the permafrost is about 1.5 meters to 2.5 meters. The higher the latitude, the thicker the permafrost. The annual average temperature is 3.5 to -2 degrees, the highest in summer is 38 degrees, the lowest in winter is about -40 degrees, the difference is about 70 degrees, and the temperature difference between day and night...
