Description
Technical field
The present invention relates to fruit vegetables storing technical fields, and in particular to a kind of fruit and vegetable air-conditioning transport vehicle using dry ice.
Background technology
Refrigerating plant is mainly used for refrigeration and the Refrigerated Transport of food.Dry ice refrigerator car first makes air be changed with dry ice when working
Then heat makes air after cooling circularly cooling in compartment by ventilation blower.The cell of rear fruits and vegetables is adopted still in carry out activity, is exhaled
Suction effect promotes the nutriment of fruits and vegetables to be consumed, while generating heat and moisture, causes fruits and vegetables rotten and rotten.
Traditional dry ice refrigerator car heat-insulated dry ice container of four wall of device in compartment is equipped with freon disk in dry ice container
It manages, freon heat exchanger is housed, the freon steam of endothermic gasification enters the coil pipe in dry ice container, quilt in compartment in compartment
It is condensed after dry ice cooling outside coil pipe, enters back into evaporator sweat cooling in compartment, structure is complex, and evaporator is empty
Gas Cooler needs refrigerating medium, maintenance cost higher, it is also necessary to carry out defrosting work, and load is heavier, be acted on without controlled atmosphere.
Also a kind of structure of dry ice refrigeration refrigerator car is simple, and investment cost is relatively low, but its cooling rate it is slower and it is spontaneous freeze,
Cause Temperature Distribution in compartment not uniform enough, cannot keep compartment temperature constant state, is unsuitable for the conveying of frozen food.
Invention content
A kind of dry ice air adjusting refrigerated vehicle that the purpose of the present invention is in view of the deficiencies in the prior art, provide, in fruit
Mechanical damage can be slowed down in the transporting procedures of vegetable, adjusting refrigerator car reaches suitable storage temperature, optimal guarantee storage pair
The script of elephant.
The present invention is a kind of dry ice air adjusting refrigerated vehicle, including babinet, heat insulation tank, temperature sensor, co2Concentration sensor and
Controller, the heat insulation tank are mounted in babinet, multilayer insulating panel are placed in heat insulation tank, dry ice is placed on every layer of shelf, on shelf
Multiple through-holes are set；Heat preservation upper end is connected with the air-supply passage one of frequency conversion fan one and shut-off valve one, air-supply passage one
The top layer in babinet.The bottom of air-supply passage one is the air-supply plate for being provided with multiple holes, and heat insulation tank bottom end is connected with change
The air-supply passage two of frequency wind turbine two and shut-off valve two, air-supply passage two are provided with fresh air between frequency conversion fan two and shut-off valve two
Outlet；Be connected with controller temperature sensor and co are provided in carriage body2Concentration sensor, the frequency conversion fan one and frequency conversion wind
Machine two is connect with controller respectively.
The present invention has many good qualities compared with conventional refrigeration mode：
Operating aspect：Dry ice air adjusting refrigerated vehicle is simple in structure, not complicated excessive parts, and what reduction failure occurred can
Can, reliability of operation is improved, maintenance cost is reduced；More complex compared to tradition machinery refrigerant system configurations, parts are more, work
It is big to make pressure, is susceptible to equipment fault and system leak.And dry ice charges that speed is fast, the carrying of low-temperature receiver is not necessarily to, without special
Industry personnel operate, easy to use, and it is fast to charge speed than traditional cold plate refrigerator container.
The cooling rate of dry ice refrigeration is fast, and when cooling is smaller to the cytoclasis of fruits and vegetables tissue, and the titanium dioxide of low temperature
Carbon gas is to be imported in case from top of the box, then be subject to a certain amount of ventilation quantity, and the temperature inside the box easily reaches uniformly, fruits and vegetables energy
It is enough quickly generally in cold storage condition, it is rotten to effectively prevent fruits and vegetables.And the co that gasification generates2Gas two improves case
Interior co2Concentration inhibits the respiration of fruits and vegetables.
Description of the drawings
Fig. 1 show a kind of schematic diagram of dry ice air adjusting refrigerated vehicle of the present invention.
Specific implementation mode
Dry ice air adjusting refrigerated vehicle of the present invention is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, dry ice air adjusting refrigerated vehicle includes air-supply plate 1, babinet 2, frequency conversion fan 1, frequency conversion fan 28, cuts
Only valve 1, heat insulation tank 5, dry ice 6, shelf 7, temperature sensor 9, co2Concentration sensor 10, controller 11；The heat insulation tank peace
In babinet, multilayer insulating panel is placed in heat insulation tank, dry ice is placed on every layer of shelf, and multiple through-holes are arranged on shelf；Heat insulation tank
Top is connected with the air-supply passage one of frequency conversion fan one and shut-off valve one, and air-supply passage one is located at top layer in babinet.Air-supply
The bottom in channel one is the air-supply plate for being provided with multiple holes, and heat insulation tank bottom end is connected with frequency conversion fan two and shut-off valve two
Air-supply passage two, air-supply passage two are provided with fresh air outlet between frequency conversion fan two and shut-off valve two；Be provided in carriage body with
Controller 11 is connected temperature sensor 9 and co2Concentration sensor 10, the frequency conversion fan one and frequency conversion fan two respectively with control
Device connects.As the co in refrigerator car2When excessive concentration, opens frequency conversion fan 28 and carry out fresh air introduction, it is suitable to reach
Gas concentration lwevel.When fruits and vegetables, which are put into, to be transported in carriage body, consult related data and can get the best guarantor of the storage object
Deposit temperature and co2Concentration range controls dry ice amount of vaporization, to reach suitable temperature value and co by controller2Concentration value,
And it closes frequency conversion fan 1 and terminates gasification.Work as co2When concentration sensor 10 detects excessive concentration, frequency conversion fan 8 can be opened and drawn
Enter fresh air, composition of air in regulating container, because of excessively high co2Content can cause fruit to rot instead.And low temperature
Carbon dioxide gas is to be imported in case from top of the box, then be subject to a certain amount of ventilation quantity, and the temperature inside the box easily reaches uniformly,
Fruits and vegetables can be quickly be in cold storage condition, it is rotten to effectively prevent fruits and vegetables.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, without departing from the principle of the present invention, the guarantor that several improvements and modifications are also considered as the present invention can be also made
Protect range.
