Description
技术领域technical field
本发明涉及果蔬贮藏技术领域，具体涉及一种利用干冰的果蔬气调运输车。The invention relates to the technical field of fruit and vegetable storage, in particular to a fruit and vegetable air-conditioning transport vehicle using dry ice.
背景技术Background technique
制冷装置主要用于食品的冷藏及冷藏运输。干冰冷藏车工作时先使空气与干冰换热，然后借助通风机使冷却后的空气在车厢内循环制冷。采后果蔬的细胞仍在进行活动，呼吸作用促使果蔬的营养物质被消耗，同时产生热和水分，造成果蔬腐烂和变质。Refrigeration devices are mainly used for refrigeration and refrigerated transportation of food. When the dry ice refrigerated truck is working, it first exchanges heat between the air and the dry ice, and then uses the fan to circulate the cooled air in the compartment for refrigeration. The cells of harvested fruits and vegetables are still active, and respiration promotes the consumption of nutrients of fruits and vegetables, and at the same time generates heat and moisture, causing fruits and vegetables to rot and deteriorate.
传统的干冰冷藏车在车厢中装置四壁隔热的干冰容器，干冰容器中装有氟利昂盘管，车厢内装有氟利昂换热器，在车厢内吸热气化的氟利昂蒸汽进入干冰容器中的盘管，被盘管外的干冰冷却后凝结，再进入车厢内蒸发器蒸发制冷，其结构较为复杂，且蒸发器是空气冷却器，需要载冷剂，维修费用较高，还需要进行融霜工作，且负荷较重，没有气调作用。还有一种干冰制冷冷藏车的结构简单，投资费用较低，但其降温速度较慢且自发进行制冷，导致车厢内温度分布不够均匀，无法保持车厢恒温状态，不适于冻结食品的输送。The traditional dry ice refrigerated truck is equipped with a four-wall insulated dry ice container in the compartment. Freon coils are installed in the dry ice container, and a Freon heat exchanger is installed in the compartment. The Freon vapor absorbed and vaporized in the compartment enters the disk in the dry ice container. The tube is cooled by the dry ice outside the coil and then condenses, and then enters the evaporator in the compartment for evaporation and cooling. Its structure is relatively complicated, and the evaporator is an air cooler, which requires a refrigerant, and the maintenance cost is high. It also needs to be defrosted. , and the load is heavy, there is no air conditioning effect. There is also a dry ice refrigerated refrigerated vehicle with simple structure and low investment cost, but its cooling speed is slow and it refrigerates spontaneously, resulting in uneven temperature distribution in the compartment, unable to maintain a constant temperature state in the compartment, and is not suitable for the transportation of frozen food.

本发明与传统制冷方式相比有很多优点：Compared with traditional refrigeration methods, the present invention has many advantages:
操作方面：干冰气调冷藏车结构简单，没有复杂的多余部件，减少故障出现的可能，提高运行的可靠性，降低了维修费用；相比传统机械制冷系统结构较复杂，零部件多，工作压力大，容易出现设备故障和系统泄漏。且干冰充灌速度快，无需冷源的搬运，也无需专业人员操作，使用方便，比传统冷板式冷藏集装箱充灌速度快。In terms of operation: the structure of the dry ice air-conditioned refrigerated vehicle is simple, there are no complicated redundant parts, the possibility of failure is reduced, the reliability of operation is improved, and the maintenance cost is reduced; compared with the traditional mechanical refrigeration system, the structure is more complex, there are many parts, and the working pressure Large, prone to equipment failure and system leakage. Moreover, the filling speed of dry ice is fast, there is no need to carry the cold source, and no professional operation is required. It is easy to use and faster than the traditional cold plate refrigerated container.
干冰制冷的降温速度快，降温时对果蔬组织的细胞破坏较小，而且低温的二氧化碳气体是从箱体顶部导入箱内，再加以一定量的通风量，箱内温度很容易达到均匀，果蔬能够很快的整体处于冷的储存环境，有效地防止了果蔬变质。且气化产生的co2气体二提高箱内co2浓度，抑制果蔬的呼吸作用。The cooling speed of dry ice refrigeration is fast, and the cell damage to the fruit and vegetable tissue is small when cooling down, and the low-temperature carbon dioxide gas is introduced into the box from the top of the box, and with a certain amount of ventilation, the temperature in the box can easily reach uniformity, and the fruits and vegetables can Soon the whole is in a cold storage environment, which effectively prevents the deterioration of fruits and vegetables. And the co2 gas produced by gasification increases the co2 concentration in the box and inhibits the respiration of fruits and vegetables.

The bottom of the air supply channel 1 is an air supply plate with a plurality of holes. The bottom of the insulation tank is connected to the air supply channel 2 with the frequency conversion fan 2 and the stop valve 2. The air supply channel 2 is between the frequency conversion fan 2 and the stop valve 2. A fresh air outlet is provided between them; a temperature sensor 9 and a CO2 concentration sensor 10 connected to a controller 11 are arranged in the compartment, and the first and second variable frequency fans are respectively connected to the controller. When the CO2 concentration in the refrigerated vehicle is too high, turn on the frequency conversion fan 28 to introduce fresh air to achieve a suitable carbon dioxide concentration. When the fruits and vegetables are put into the box for transportation, the best storage temperature and co2 concentration range of the storage object can be obtained by consulting relevant information, and the gasification amount of dry ice is controlled by the controller to achieve the appropriate temperature value and co2 concentration value. And close the frequency conversion fan-3 to terminate the gasification. When the co 2 concentration sensor 10 detects that the concentration is too high, the frequency conversion fan 8 can be turned on to introduce fresh air to adjust the air composition in the container, because the excessive co 2 content will cause the fruit to rot on the contrary. And the low-temperature carbon dioxide gas is introduced into the box from the top of the box, and with a certain amount of ventilation, the temperature in the box can easily reach a uniform temperature, and the fruits and vegetables can be quickly placed in a cold storage environment, effectively preventing the deterioration of the fruits and vegetables.
