Vacuum fresh-keeping storage device for ocean-going ship

Abstract

The invention relates to a storage device for an ocean-going ship. A vacuum fresh-keeping storage device comprises a vacuum storage room (5) for storing food and keeping the food fresh, an air extraction system for extracting vacuum, a humidifier system for humidification and a ventilation system for ventilation, a refrigerating unit (8) for refrigeration and a temperature control system of a temperature-detecting unit, and an automatic control system including a data collection, measurement and control system (23). A warmth-keeping enclosure (6) is arranged at the periphery of the vacuum storage room (5) for wrapping and enclosing the vacuum storage room (5) and a protection frame (20) is disposed at edges of the four angles, the upper part and the lower part of the warmth-keeping enclosure (6). A lifting ring (4) is arranged at the upper part of the protection frame for lifting and a plurality of anchoring foundations are disposed at the lower part of the protection frame for anchoring. A locking device is fixedly arranged inside the vacuum storage room (5) to hold a shelf (31) of a plastic circulating frame (37) for preventing the shelf from falling off. The invention provides the vacuum storage device for the ocean-going ship to store vegetables and raw meat and keep the vegetables and meat fresh without frozen storage for a long time and also provides the device to store raw and cooked food without frozen storage.

Description

[0001] Technical field [0002] The invention relates to a storage and fresh-keeping device, in particular to a storage device for ocean-going ships, and a vacuum storage and fresh-keeping device for fresh agricultural and sideline products and food safety preservation. Background technique [0003] Ocean-going merchant ships, fishing vessels, and naval vessels are long-distance and long-term maritime transportation or warfare tools. In order to ensure smoothness and safety, it is necessary to provide fresh vegetables to the crew. At present, one of the biggest difficulties in navigating operations at sea One is the severe shortage of fresh vegetables, especially fresh green leafy vegetables. [0004] The well-known technical methods for keeping fresh vegetables and fruits include refrigeration and air conditioning. The equipment includes: cold storage, controlled atmosphere storage, or modified atmosphere packaging and then put it in the cold storage for refrigeration. Generally...

AI Technical Summary

Problems solved by technology

However, can it be applied to the preservation of fruits and vegetables during ocean transportation on sea ships? In harsh environments such as humidity, corrosion, vibration, shaking, and large temperature differences at sea, whether the decompression storage device can meet these special requirements, and how to meet these requirements has always been an urgent and difficult task for scientific and technological workers. It is the reason why there is no technical method of vacuum storage and fresh-keeping equipment for sea-going ships so far.
