Device and method for rapidly slowing down fruit respiration

Abstract

The invention discloses a device and a method for rapidly slowing down fruit respiration. The device comprises a storage box, wherein a sealing door is hinged to an opening in one end of the storage box, a nitrogen cylinder is fixedly installed on the surface of one end of the storage box, a first valve is fixedly installed at one end of the nitrogen cylinder, an air inlet pipe is fixedly installed at the other end of the first valve, an air pump is fixedly installed on the surface of the other end of the storage box, a second valve is fixedly installed at one end of the air pump, an air suction pipe is fixedly installed at the other end of the second valve, an air suction through hole is formed in the surface of one side of the air suction pipe, and the surfaces of the air inlet pipe andthe air suction pipe are fixedly connected to the two sides of the interior of the storage box. The device conforms to the fruit physiological mechanism, cold damage caused by a rapid cooling method cannot be generated, gas comburent residual pollution of controlled atmosphere storage cannot be generated, food safety is guaranteed, and the device is simple, easy to operate, low in use cost and beneficial to application and popularization.

Description

technical field [0001] The invention relates to the field of fruit storage, and more specifically relates to a device and method for rapidly slowing down fruit respiration. Background technique [0002] Of course, in today's social life, it is necessary to transport and circulate fruits from different regions, and in order to ensure the quality of fruits, fresh-keeping storage is required. [0003] But in the existing fruit preservation mode, mostly adopt the following methods, (1) quick cooling: this technology generally will be specially built quick-freezing room in the fruit storehouse, uses the lower temperature and bigger cooling capacity than storage temperature, Lower the temperature quickly to slow fruit respiration. However, this method has been rarely used due to high construction costs, high energy consumption, poor physiological adaptability of fruits, easy to cause chilling injury, and high storage cost. (2) Vacuum packaging: positive empty packaging uses posit...

However, this method has been rarely used due to high construction costs, high energy consumption, poor physiological adaptability of fruits, easy to cause chilling injury, and high storage cost. (2) Vacuum packaging: positive empty packaging uses positive empty packaging belts to pass Pack and extract the air in the bag to slow down the respiration of the fruit. This method has been used in recent years and found that the effect is not obvious. (3) Controlled atmosphere storage: Prepared by adjusting and controlling the oxygen content of the storage warehouse. The respiration of fruit, but this method is not ideal for controlling the peak of respiration, so a new preservation method needs to be proposed
