Nitrogen filling and pressure reducing device for vegetable and fruit preservation storehouse

Abstract

The invention relates to a nitrogen filling and pressure reducing device for vegetable and fruit preservation storehouse, in particular to a pressure reducing device for filling nitrogen in a vegetable and fruit preservation storehouse. The nitrogen filling and pressure reducing device for the vegetable and fruit preservation storehouse is characterized in that the nitrogen filling and pressure reducing device comprises a preservation unit and a nitrogen source; a nitrogen inlet and an exhaust port are arranged on the preservation unit; an exhaust electric valve is disposed on the exhaust port; a pressure reducing unit is arranged between the nitrogen source and the preservation unit; a detection unit is connected to the preservation unit. The nitrogen filling and pressure reducing devicefor the vegetable and fruit preservation storehouse has the advantages of being safe and reliable, capable of eliminating potential unsafe hazards to a fresh-keeping storehouse and nearby staff and especially suitable for nitrogen filling of fresh-keeping storehouses on ocean-going ships.

Description

technical field [0001] The invention relates to a nitrogen filling and decompression device. Specifically, it is a decompression device for filling nitrogen into the vegetable and fruit fresh-keeping store. It is especially suitable for filling nitrogen in fresh-keeping warehouses on ocean-going ships. Background technique [0002] On some ocean-going ships, in order to ensure that the crew can eat fresh vegetables and fruits during the long-term ocean-going process, most of the ocean-going ships are equipped with vegetable and fruit fresh-keeping stores. In order to ensure that the fruits and vegetables in the vegetable and fruit fresh-keeping store will not deteriorate for a long period of time, it is necessary to regularly fill the vegetable and fruit fresh-keeping store with nitrogen. At present, most of the vegetable and fruit fresh-keeping stores on ships are equipped with self-generating nitrogen-generating equipment. This kind of spontaneous nitrogen generating eq...

AI Technical Summary

Problems solved by technology

This kind of spontaneous nitrogen generating equipment has complex structure and high manufacturing cost

In order to solve the above problems, large-scale nitrogen-generating equipment is installed on some ships. Although the manufacturing cost of this large-scale nitrogen-generating equipment is low, the pressure of the produced nitrogen is high. If it is directly charged into the fresh-keeping store, it will make the fresh-keeping store Overpressure will bring unsafe hazards to the fresh-keeping warehouse and nearby staff, which is very unsafe
