Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] Such as Figure 1 to Figure 3 As shown, the fruit and vegetable fresh-keeping unit for ships of the present invention is composed of a storage body 1, refrigeration equipment, air-conditioning equipment, electronic control equipment 2, shelves 3, and the like. Storage body 1 is a polyurethane pressure-bearing storage board with a thickness of 120-150 mm, which can meet the pressure-bearing and tightness requirements of a controlled atmosphere warehouse after assembly. The refrigerating equipment includes coil pipes 5, refrigerating valve parts, and refrigerant pipelines, and the air-conditioning equipment includes oxygen-generating membranes 7 and gas pipelines. Refrigeration valves, refrigerant pipelines, air-conditioning equipment and lighting equipment 8 are all installed in the interlayer 80-100mm away from the side plate of the warehouse, t...

Abstract
The invention relates to a fruit and vegetable fresh-keeping unit for ships, which is composed of a warehouse body, a refrigeration device, a controlled atmosphere device, an electric control device and a goods shelf, the refrigeration device comprises a coil pipe, a refrigeration valve and a refrigerant pipeline, and the controlled atmosphere device comprises an oxygen production film and a gas pipeline. The refrigeration valve, the refrigerant pipeline, the oxygen generation film and the lighting device are all installed in an interlayer which is 80-100 mm away from a side plate of the warehouse body, the refrigeration coil is installed in a space which is 150 mm below the lowest layer of the bottom of the goods shelf, the fan is installed in a pore plate interlayer which is 80-100 mm away from the top of the goods shelf, and the oxygen generation film is connected with the gas pipeline. According to the fruit and vegetable fresh-keeping unit for the ship, long-acting fresh keeping of fruits and vegetables under high-density storage is achieved by accurately controlling the temperature of the storeroom, adjusting the gas concentration and taking intelligent control measures.
Description
technical field [0001] The invention relates to a marine food preservation technology, in particular to a marine fruit and vegetable preservation unit. Background technique [0002] At present, the most widely used food preservation technologies on ships are refrigeration preservation technology and modified atmosphere preservation technology. Among them, the precise temperature control and fresh-keeping technology in the refrigeration and fresh-keeping technology can extend the fresh-keeping time of food by reducing the temperature of the food storage environment to near the freezing point and precisely controlling the fluctuation range of the temperature to ensure the control accuracy of the temperature in time and space. The effect of improving the preservation effect of low-temperature leafy vegetables is particularly obvious. However, some problems have been found in the actual application process of this technology. For example, the improvement of the preservation eff...
