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.
