Detailed description of the invention
Technical scheme of the present invention is further illustrated by specific embodiment below in conjunction with accompanying drawing 1 ~ 4.
Fig. 1 is the schematic diagram of the storage freezer fruits and vegetables atomizing humidifying performance fresh-keeping system of one embodiment of the invention.As shown in Figure 1, fruits and vegetables atomizing humidifying performance fresh-keeping system comprises atomization system 1, at least one air-cooler 2 and humidity sensor 3, atomization system 1 comprises the atomizer 11 of at least one eruption dry fog, air-cooler 2 is provided with some cold wind outlet 21, the cold wind outlet 21 of the contiguous air-cooler 2 of atomizer 11 is arranged, the opposite side that air-cooler 2 deviates from atomizer 11 is provided with humidity sensor 3, the cold wind outlet 21 of air-cooler 2 is consistent with the spray outlet direction of atomizer 11, and humidity sensor 3 and atomizer 11 are all connected with controller.The atomizer 11 that " dry fog " of the present invention Humidity Control adopts, that purifying waste water with filtering compressed air is raw material, extremely fine water particle is erupted in storage freezer, 95 ~ 98% accurate relative humidity can be provided, thus stop fruits and vegetables dehydration, keep freshness, and strengthen the resistance to pathogen.Wherein, the size of water particle is 2 ~ 10 μm, can evenly spread rapidly, is formed " dry fog ", and (>=-1 DEG C) can not condense solidifying water at low temperatures, makes in storage freezer 100 in " dry and comfortable " state, fruits and vegetables and packing material surface not ponding thereof.
The present embodiment is by arranging the cold wind outlet 21 of contiguous for atomizer 11 air-cooler 2, and the dry fog erupted by atomizer 11 quickly diffuses to each corner of storage freezer 100 under the effect of air-cooler 2; In storage freezer 100, the humidity that air-cooler 2 deviates from the opposite side of atomizer 11 is minimum, and the opposite side therefore by deviating from atomizer 11 at air-cooler 2 arranges humidity sensor 3, and the humidity in each corner in storage freezer 100 can be made all to meet the demands; Humidity sensor 3 is all connected with controller with described atomizer 11, can automatically accurately control and regulate the humidity in storage freezer 100, make storage freezer 100 remain high humility.
In above-described embodiment, the start and stop of air-cooler 2 control by the refrigeration system of preserving freezer 100 with the temperature in storage freezer 100.
In the present embodiment, atomizer 11 and multiple air-cooler 2 that multiple different size spray amount is installed can be selected according to the size of storage freezer, each air-cooler 2 can arrange multiple cold wind outlet 21, the cold wind outlet 21 of all contiguous air-cooler 2 of atomizer 11 is arranged, and each atomizer 11 is all connected with controller, the humidity in each corner of storage freezer 100 is made to be consistent fast further.
As the storage freezer 100 that storage is less, in storage freezer 100, an atomizer 11, air-cooler 2 is set, air-cooler 2 can arrange a cold wind outlet 21, as shown in Figure 2, air-cooler 2 is provided with a cold wind outlet 21, and atomizer 11 exports 21 with the cold wind of air-cooler 2 and coaxially arranges; Because atomizer 11 is just to the cold wind outlet 21 of air-cooler 2, the dry fog that therefore atomizer 11 sprays can quickly diffuse to each corner of storage freezer 100 under the effect of air-cooler 2; Certainly, as another embodiment of the present invention, as shown in Figure 3, air-cooler 2 also can arrange two cold wind outlets 21, and atomizer 11 is arranged between two cold wind outlets 21.The cold wind of two cold wind outlet 21 blowouts can concentrate the dry fog to atomizer 11 sprays to spread.
As the storage freezer 100 that storage is larger, in storage freezer 100, two, three, four even more air-coolers 2 can be set, air-cooler 2 can arrange one, two, three even more cold wind outlets 21, an atomizer 11 can be set respectively at the middle part of each air-cooler 2, also an atomizer 11 can be set respectively at the middle part of each cold wind outlet 21, to improve amount and the diffusion velocity of dry fog, keep the even high humility in freezer.
