Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1 to 3, the fresh-keeping unit for fruits and vegetables for ships of the present invention is composed of a storage body 1, a refrigeration device, an air conditioning device, an electric control device 2, a shelf 3, etc. The storehouse body 1 is a polyurethane pressure-bearing storehouse plate with the thickness of 120-150 mm, and can meet the pressure-bearing and tightness requirements of the air-conditioned storehouse after being assembled. The refrigerating equipment comprises a coil pipe 5, a refrigerating valve and a refrigerant pipeline, and the air conditioning equipment comprises an oxygen producing membrane 7 and a gas pipeline. The refrigeration valve, the refrigerant pipeline, the air conditioning equipment and the lighting equipment 8 are all arranged in an interlayer 80-100 mm away from a side plate of the storage, the refrigeration coil 5 is arranged in a space 150mm below the lowermost layer at the bottom of the goods shelf, and the fan 6 is arranged in an interlayer 9 of a pore plate 80-100 mm at the top. The oxygen-making membrane 7 is connected with a gas pipeline.
The front of the storehouse body 1 is provided with a storehouse door 11 and a liquid crystal operation panel 10, and the bottom is provided with a water outlet 12. The upper part of the goods shelf 3 in the storehouse body 1 is provided with a hole plate 9. A container 4 is placed on the pallet 3. The lighting device 8 in the storehouse body 1 adopts an LED lamp.
And when the warehouse door is opened, the LED lamp is lightened, the equipment cannot be seen when the warehouse enters, and the whole warehouse is clean and tidy. The liquid crystal panel is embedded on the surface of the side warehouse board, so that the operation of personnel outside the warehouse is facilitated. All the electric control equipment are arranged in the box body with the top height of 100mm, so that the operation and maintenance are convenient, and the influence of the low-temperature and high-humidity environment in the warehouse on the use reliability of the electric control equipment can be effectively avoided.
The advantages of the precise temperature control fresh-keeping technology and the controlled atmosphere fresh-keeping technology are fully utilized and combined. In the first half of the fresh-keeping period with strong accurate temperature control fresh-keeping effect, the modified atmosphere fresh-keeping does not produce effect, but the nitrogen is slowly produced by the oxygen-making film by utilizing the time until the nitrogen concentration in the storehouse meets the requirement. In the latter half of the preservation period, the precise temperature control and the modified atmosphere preservation act together, so that the preservation quality of the fruits and vegetables is improved. The method does not need to additionally configure large-scale nitrogen making equipment, reduces the equipment number of the preservation system, improves the overall use safety, and reduces the equipment management work, and the technical scheme has the following characteristics:
1) the function integration level is high. The fresh-keeping unit integrates a coil pipe, a fan, a regulating valve, nitrogen making, ethylene removing and ozone generating equipment, and a liquid crystal operation panel is embedded in the outer surface of the front storage plate and used for achieving the functions of refrigeration, defrosting, air conditioning, intelligent vegetable and fruit management and the like.
2) The device is independently controlled, independently powered, flexibly used and can be loaded, combined and matched for use as required. The preservation unit is provided with a control system, receives information of stored food input by the liquid crystal panel, automatically controls food preservation environmental conditions such as temperature and nitrogen concentration in the unit and sends a cold source demand signal to the host.
3) The storage capacity rate is high. All equipment of the unit is designed in a miniaturized mode, equipment such as a fan, a coil pipe, lighting, an oxygen making membrane, a pipeline and a cable are reasonably placed in a space with the periphery of 80-100 mm, the rest space can be completely used for storing goods, and the storage capacity rate can reach over 68%.
4) The human-computer interface is friendly, and the use and the operation are convenient. The liquid crystal operation interface is internally provided with a preservation database, weight calculation is carried out according to names and weights of different dishes input by a user, recommended values of the temperature and the gas component concentration of the storehouse are given, and then the intelligent control process is automatically carried out until a preservation task is finished.
5) The safety is high. Compared with the traditional air-conditioned storehouse, the air-conditioned preservation unit does not need to be additionally provided with a nitrogen generating unit, and the net volume of the preservation unit is about 5-8 m3When in use, the nitrogen and oxygen balance time is short because the nitrogen amount is small, and the dishes can be taken out immediately after the door is opened.
