Embodiment Construction

[0017] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0018] Such as figure 1 As shown, the low-vacuum vegetable fresh-keeping refrigerator of the present invention mainly includes a warehouse body, a refrigeration unit, a temperature control system, a vacuum pressure and protection system, a repressurization door opening system, a humidification system, a disinfection and sterilization system, a ventilation system and a PLC automatic control system, etc. Several parts, each part is relatively independent and interrelated, for example, through the temperature control system to control the work of the refrigeration unit, so that the storage can reach the required low temperature environment; vacuum preservation environment, but when it is necessary to open the door to pick up vegetables, the door can only be opened to pick up vegetables afte...

Abstract

The invention discloses a rough vacuum vegetable fresh-preserving cold storage which comprises a storage body, a refrigerating unit, a temperature control system, a vacuum pressure and protection system, a repressuring door-opening system, a humidification system, a disinfecting and sterilizing system, an air exchange system and a PLC (Programmable Logic Controller) automatic control system. The temperature control system controls the operation of the refrigerating unit so that the fresh-preserving cold storage achieves a required environment, the vacuum pressure and protection system provides a required vacuum fresh-preserving environment for the fresh-preserving cold storage, and the repressuring door-opening system is used for pressure relief. The storage body, the refrigerating unit, the temperature control system, the vacuum pressure and protection system, the repressuring door-opening system, the humidification system, the disinfecting and sterilizing system and the air exchange system are all connected with the PLC automatic control system. After various parameters of a man-machine dialog interface of the PLC automatic control system are set, the storage body, the refrigerating unit, the temperature control system, the air exchange system and other parts operate automatically. The invention can increase and enhance the effect of low-temperature vegetable fresh preservation.

Description

technical field [0001] The invention relates to a fresh-keeping refrigeration technology, in particular to a low-vacuum vegetable fresh-keeping refrigerator. Background technique [0002] With the rapid development of the national economy, people's living standards are getting higher and higher. Consumption is not only satisfied with the demand for "eat well", but also requires the market to provide better "eat well" services, requiring The food supply can meet the fundamental requirements of "green, safe, hygienic, and high-quality", especially for personnel working in places such as ocean-going ships, special ships, islands, and remote areas, the replenishment and supply of fresh vegetables has always been a problem , this project has always been a blank in China. Though, there is a kind of controlled atmosphere storehouse in China at present, its manufacture and maintenance cost are very high, and its fresh-keeping effect is also not ideal, is difficult to obtain popular...
