Description
Technical field
The present invention relates to postharvest technology of fruits and vegetables field, particularly relate to a kind of decompressing storage device.
Background technology
The subatmospheric pressure storage of fresh agricultural product is to be placed in closed container by product, and in extracting container out, partial air makes pressure drop
To regulation requirement, carrying a certain amount of fresh humid air through pressure regulator as required, whole system is continuously carried out
Gas exchanges, to maintain the most constant of pressure in storage container and to keep certain relative humidity, utilizes artificial cooling simultaneously
Reduce the temperature of storage environment, take away the sensible heat of product itself, respiration heat and leakage heat.
At present, the refrigeration system of decompressing storage device is primarily present techniques below problem:
The subatmospheric pressure storage that 1, the evaporimeter of refrigeration system is placed on insulation is indoor, but because subatmospheric pressure storage room air is dilute
Thin, evaporator heat exchange weak effect, need the biggest heat exchange area, take the substantial amounts of storage space in subatmospheric pressure storage room.
2, in order to keep the stability of subatmospheric pressure storage indoor, vavuum pump needs to run continuously, and when water vessel runs one section
Between need defrosting to run continuously.Current decompression stowage arrangement can only be abandoned using water vessel, flows out from subatmospheric pressure storage room
Hot and humid gas is directly over vavuum pump and discharges.The a large amount of steam carried due to the internal damp atmosphere of decompressing storage device, no
Only considerably increasing the load of vavuum pump, cause plant running energy consumption huge, also limit the type of vavuum pump, water is steamed by some
The vavuum pump of air-sensitive sense is easily damaged and does not the most work.
3, the air-cooling apparatus of current decompression stowage arrangement is all placed in greatly the subatmospheric pressure storage chamber interior of high humility, easily makes
Become a large amount of condensation in air-cooling apparatus surface, the heat exchange efficiency of extreme influence cooling device, thus add the energy of refrigeration unit
Consumption.
4, the vavuum pump of existing decompressing storage device is mostly only with a vavuum pump, for meeting the subatmospheric pressure storage starting stage
Quickly the pressure in storeroom is reduced to setting value, it is necessary to use powerful vacuum pump, and subatmospheric pressure storage runs steadily in the long term
During, it is only necessary to a small amount of gas extracted out by vavuum pump, and now powerful vacuum pump not only operational efficiency is low, energy consumption big, Er Qierong
Easily break down.
5, the damping device of current decompression stowage arrangement uses electrical heating to produce steam mostly, and steam carries heat and enters
Enter subatmospheric pressure storage room, add the thermic load of device, improve the energy consumption of device.
6, the extract system of current decompression stowage arrangement, humidification system, gas handling system, refrigeration system etc. are relatively independent, often
Subatmospheric pressure storage room will be opened a hole and is attached thereto by individual system, and a large amount of perforates cause subatmospheric pressure storage room slip to increase, thus
Add the load of vavuum pump, add the energy consumption of device.
In sum, owing to current decompression stowage arrangement exists above-mentioned technical problem, cause plant running unstable, and energy
Consumption is big.

Device 38, the steam in air is condensed into frost by the second water vessel 38 and is attached to the second water vessel 38 surface, the second water vessel
38 trapping the consumed colds of steam are provided by catching water refrigerating machine group 44.While second water vessel 38 catches water, first catches water
Device 41 built-in electric heating tube energising to frost layer heat, to the first water vessel 41 defrosting, be attached to the first water vessel 41 surface
Frost layer be heated thawing, defrosting water is flowed by the first row water control valve 46 opened along water pipe by bottom the first water vessel 41
Enter header tank 47.After arrival sets time interval and the first water vessel 41 defrosting terminates, it is switched to the first water vessel 41 and catches
Water running carries out defrosting to the second water vessel 38 simultaneously.So alternate cycles is carried out, thus realizes the trapping of continuous type water-trapping system
Continuous operation.
The described built-in liquid level sensor of header tank 47 43 monitors liquid level in case in real time, if monitoring liquid in header tank 47
Position too high, if now the first water vessel 41 catching aqueous mode run, then temporary close second row water control valve 27, if second
Water vessel 38 is catching water running pattern, then temporary close first row water control valve 46, opens relief valve 25 afterwards and makes outside
Air enter header tank 47, after header tank 47 internal and external pressure balance, open draining valve 26 can draining rapidly, treat header tank 47
After internal water is the most drained, close draining valve 26 and relief valve 25.If now the first water vessel 41 is catching aqueous mode fortune
OK, then open second row water control valve 27, if the second water vessel 38 is catching water running pattern, then open first row water management
Valve 46, whole drainage procedure does not interferes with the normal of continuous type water vessel and runs continuously.The high humility extracting subatmospheric pressure storage room out is empty
In gas, major part steam is trapped by continuous water-trapping system 30, enters back into frequency conversion vavuum pump 29 afterwards, greatly reduces frequency conversion true
The load of empty pump 29, thus reduce the energy consumption of frequency conversion vavuum pump 29.
