Preferably, described cooler is a water-cooled, and used cooling water is placed in the said fruits and vegetables storage device; Described gas generator is for being equipped with SO
2/ Cl
2Steel cylinder, Te Keduo (TBZ) fumicants generator, Cl
2At least a in generator and the sec-butylamine vaporizer, the discharge gas flow of each gas generator is regulated through valve; Said fruits and vegetables storage device is an air-conditioned cold store.
A kind ofly use above-mentioned fruits and vegetables anti-mildew fresh-keeping equipment to carry out fresh-keeping method, may further comprise the steps:
1) opens the drain tap and the top air intake valve of storage tank, make pipeline connection, constitute closed circuit;
2) gas in the corresponding gas generator is discharged into pipeline, and control piper internal pressure and flow and gas temperature;
3) gas concentration of fruits and vegetables storage device is flowed out in monitoring in real time, and the gas of discharging from the fruits and vegetables storage device circulates in pipeline under the dynamic action of circulating pump;
4) after reaching predetermined concentration, close the gas of gas generator and supply with, form the inner loop system, carry out gas flow and fumigate;
5) behind stifling the end, close each valve, open the controlled atmosphere system of fruits and vegetables storage device.
In addition, this method also comprises a reclaiming clean step, and this step comprises: the top air intake valve of closing storage tank; Open its underpart and carry out valve; Participate in circulation after making recyclegas through the reagent removal solution of storage tank bottom once more, the concentration that the detector of Real Time Observation fruits and vegetables storage device outlet shows is after concentration reaches residual requirement; Close all valves and power set, make the fruits and vegetables storage device remain on a lower fresh-keeping gas concentration.
Equipment of the present invention is fruits and vegetables precooling, logistics, sale is fresh-keeping and freezer, the fresh-keeping auxiliary equipment of air conditioned storage, can be with the various antistaling agents that keep drug effect with gaseous state, like sulfur dioxide (SO
2), ozone (O
3), TBZ, sec-butylamine, chlorine dioxide (ClO
2), ethene, 1-methyl cyclopropene (1-MCP) etc.; Through freshness preserving equipment,, quantitatively, regularly, regularly feed various antistaling agents according to the preserving fruit and vegetable utilizing technical data; Reach different preservation and freshness stage (at interval, regularly) the high concentration sterilization processing of fruits and vegetables; Be in the low concentration bacteriostasis for a long time, so both reached antiseptic effect, it is residual to reduce medicament again.Solved by the inhomogeneous fruits and vegetables injury that causes of antistaling agent release concentration, can be used for multiple antistaling agent and the processing of physiological regulation agent different fruits and vegetables.
The specific embodiment
To combine the specific embodiment accompanying drawing that equipment of the present invention is elaborated below.
As shown in Figure 1; The total flow controller 2 that fruits and vegetables anti-mildew fresh-keeping equipment of the present invention comprises by the road the storage tank 1 that is communicated with successively, control overall fresh-keeping air-flow, cooling device 3, fresh-keeping gas is dispensed to desirably distributor 4 in the fruits and vegetables storage device 5 of a plurality of parallel connections, detects a plurality of gas-detecting devices 6 of each constituent concentration in the gas that each fruits and vegetables storage device 5 discharges and for fresh-keeping gas provides the pump 7 of circulation power in real time respectively, described pump 7 is communicated with the upper and lower of storage tank 1 respectively by the road.In addition, storage tank 1 also is communicated with a plurality of gas generators 8 by the road, and the capacity of each gas generator 8 is all regulated through valve.Simultaneously, the pipeline between storage tank 1 and the total flow controller 2 is provided with valve K3 and is parallel with Pressure gauge 9, so that storage tank effluent air pressure is monitored.
Wherein, described storage tank 1 is the pot type structure, and it comprises locally-connected two parts up and down, above described storage tank, adopts the form or the mixed flow structure of packed tower, is purified and evenly release after the air-flow that the gas that generator is produced perhaps refluxes gets into.Be equipped with reagent removal solution in the storage tank bottom, like the NaOH of high concentration etc., the gas of circulating reflux can reduce the fresh-keeping gas concentration in the fruits and vegetables storage device after through reagent removal solution, makes it remain on low concentration, fruits and vegetables is damaged avoiding.
Described cooler 3 adopts water-cooling patterns, and cold water is positioned in the fruits and vegetables storage device, make it to have with the storehouse in the same temperature, even lower.When gas passes through cooler, can gas cooled to the temperature approaching with the fruits and vegetables storage device be prevented in stifling process, to cause the storehouse temperature fluctuation.
Described fruits and vegetables storage device 5 can be for the container of fruit vegetables storing, like casing, and bottle or air-conditioned cold store.
Described gas generator 8 can be varied, can be the steel cylinder that fills gas, also can instead give birth to device for the TBZ fumicants, or the sec-butylamine vaporizer etc., it is communicated to storage tank 1 top with control valve by the road.
When fumigating, open the drain tap K3 and the top air intake valve K6 of storage tank 1 earlier, make pipeline UNICOM; Open gas import and export valve K4, the K5 of each fruits and vegetables storage device 5 then; Open the total valve K2 on the pipeline between gas generator 8 and the storage tank 1 again; A plurality of branch road valve K1; Make the gas in the gas generator 8 be discharged into pipeline, and flow into the fruits and vegetables storage device that each needs according to the diagram direction of arrow.In this process; Can come control piper pressure through manometric reading; Come gas flow in the control piper through the total flow controller, make gas temperature be reduced to the close temperature of air-conditioned cold store through cooler again, prevent in stifling process, to cause the storehouse temperature fluctuation.Can monitor the gas concentration of discharging in real time through gas-detecting device 6, under the dynamic action of circulating pump 7, get back to basin 1 and participate in circulation once more from the gas that fruits and vegetables storage device 5 is discharged from fruits and vegetables storage device 5.After reaching finite concentration, close K2, make it to become the inner loop system, reach the stifling effect of gas flow, make to prevent the too high or too low phenomenon of local concentration for fruits and vegetables even contact antistaling agent.Behind stifling the end, close each valve, the controlled atmosphere system of beginning fruits and vegetables storage device 5 carries out air conditioned storage.
If need reclaiming clean; Then open K7, close K6, under the dynamic action of circulating pump 7, get back to basin 1 bottom from the gas of fruits and vegetables storage device 5 discharges and make gas pass through basin lower floor; Medicament in the fresh-keeping gas of reagent removal solution absorption in the basin, gas are after treatment participated in circulation once more.The concentration that the detector of Real Time Observation fruits and vegetables storage device outlet shows; After concentration reaches residual requirement; Can close all valves and power set, and then close whole system, the fruits and vegetables storage device is remained under the lower fresh-keeping gas concentration; In effectively antibacterial, effectively prevent residual generation.
