Abstract
A kind of dresser sterilizing freshness-retaining device, arranges Burdick lamp by central authorities in sterilization tank, and is looped around the photocatalyst TiO of Burdick lamp periphery
2net, utilizes fan to make air circulation process in dresser, sterilizes and purify gas in dresser and body surface.This utility model has good exterminating bacterium effect, can be widely used in the exterminating bacterium in storage food, sale of foodstuffs, displaying food products such as food show case, food display cabinet, food service cabinet, food cabinet, food cabinet.
Description
Technical field
This utility model belongs to dresser system exterminating bacterium field, is specifically related to a kind of sterilization treatment device of food display showcase.
Technical background
Dresser, as food show case, food display cabinet, food service cabinet, food cabinet, food cabinet etc. be storage food, the one of sale of foodstuffs, displaying food commonly uses container, storing, selling and showing in the process of food, easy microbial contamination or invasion and attack, cause food apoilage, affect the health of people.Useful ozone carries out the device of sterilizing to dresser in the prior art, as patent 92214622.5 electronic sterilizing food cold storage locker.As everyone knows, ozone is strong oxidizer, and ozone directly contacts fattiness food can cause oxidation as fish, meat etc., and cause the change of food quality, color and luster, local flavor and nutrition, therefore ozone is as the sterilizing existing defects of dresser.
Utility model content
There is the deficiency of microbial contamination in this utility model, provide a kind of dresser sterilizing freshness-retaining device, this device exterminating bacterium is effective, simple and convenient, with low cost at displaying, sale and foodstuff storing for above-mentioned dresser.
In order to solve the deficiency of above-mentioned technology, this utility model is achieved by the following technical solutions:
A kind of dresser sterilizing freshness-retaining device, comprise sterilization tank and be arranged on Burdick lamp, the photocatalyst net in sterilizing tank body, described sterilization tank is a tank body being provided with air inlet and air outlet, peripheral sealing, described Burdick lamp is arranged on the central part in sterilization tank, described photocatalyst net is looped around Burdick lamp periphery, at sterilization tank first, in described air inlet, then arrange drainage screen and fan, described Burdick lamp is connected with control unit with fan in described air inlet design.
Further, the sterilizing ability that the ultraviolet due to different wave length has is different, and through experimental demonstration, wavelength is that the ultraviolet sterilization ability of 253nm is the strongest, and therefore, this utility model preferably adopts the wavelength of described Burdick lamp to be 253nm.Preferred described Burdick lamp is 1cm to the distance of photocatalyst net.
Because described sterilization tank is circulated air pattern, comprise air inlet and air outlet, circulated air is formed under the drive of fan, in order to reach the object of thorough purification and sterilization in air circulation process in dresser, in order to increase the area of ultraviolet radiation to photocatalyst net, make ultraviolet exciting light catalyst produce electronics and hole pair to greatest extent, described photocatalyst net is preferably looped around Burdick lamp periphery.
Nano-TiO
2be acknowledged as a kind of safety non-toxic, harmless, non-secondary pollution, sterilization rate are high and food had to the advantage of fresh-keeping function, therefore, this utility model preferably adopts photocatalyst net to be nano-TiO
2net.
Compared with prior art, advantage of the present utility model and good effect are: dresser bactericidal unit of the present utility model by photocatalyst net and ultraviolet with the use of, excite electronics and hole pair to greatest extent, effectively can kill the microorganism in dresser, control and ensured the food not microbial contamination in dresser, photocatalyst is to the degraded of harmful gas Journal of Molecular Catalysis simultaneously, ensure that quality and the freshness of food.Owing to having killed microorganism in dresser, having degraded harmful gas in dresser, thus slow down the speed of food spoilage, ensured food safety, extended the shelf life of food.
After reading the detailed description of this utility model embodiment by reference to the accompanying drawings, other feature of the present utility model and advantage will become clearly.
Accompanying drawing explanation
Figure is the structural representation of a kind of dresser sterilization fresh device that this utility model proposes.
Detailed description of the invention
For at present to dresser, comprise the problem that food show case, food display cabinet, food service cabinet, food cabinet, food cabinet etc. all exist microbial contamination in storage food, sale of foodstuffs, displaying food products, provide a kind of bactericidal unit, by central authorities in sterilization tank, Burdick lamp is set, and photocatalyst net is set at Burdick lamp periphery, fan is utilized to make air circulation process in dresser, gas in dresser and body surface are sterilized and purifies, structure is simple, can reach the effect of dresser exterminating bacterium.
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in more detail.
Embodiment one, the dresser sterilization fresh device of the present embodiment, shown in figure, for the structural representation of a kind of dresser sterilization fresh of the present embodiment device, comprise air inlet 1, drainage screen 2, fan 3, control unit 4, sterilization tank 5, Burdick lamp 6, photocatalyst net 7, air outlet 8, described Burdick lamp 6 is arranged on sterilization tank 5 central authorities, described photocatalyst 7 net is looped around the periphery of Burdick lamp 6, described fan 3 is connected with control unit 4 with Burdick lamp 6, is controlled unlatching or the closedown of fan 3 and Burdick lamp 6 by control unit 4.
The present embodiment is that effective exciting light catalyst is to harmful microbe killing effect and the adsorption effect to the material such as ethylene, sulfide, increase the area of ultraviolet radiation to photocatalyst net 7, preferably arranging described photocatalyst net 7 is looped around around Burdick lamp 6, preferably photocatalyst net 7 and the distance of Burdick lamp 6 are set to 1cm, the wavelength of preferred Burdick lamp 6 is 253nm.
Current public domain: ultraviolet is the one of sunray is the general name of electromagnetic spectrum medium wavelength radiation from 10nm to 400nm.According to the difference of ultraviolet own wavelength, ultraviolet can be divided into long wave ultraviolet (315 ~ 400nm, UV-A), ultraviolet B radiation (280 ~ 315nm, UV-B), short wave ultraviolet (200 ~ 280nm, UV-C), vacuum ultraviolet (100 ~ 200nm, UV-C).Wavelength for ultraviolet disinfection is 250 ~ 320nm, but in this utility model, through testing and verification, the wavelength that ultraviolet disinfection ability is the strongest is 253nm.
The present embodiment photocatalyst net 7 preferably adopts nano-TiO
2net, nano-TiO
2be generally acknowledged a kind of a kind of material that can be applied to food, there is safety non-toxic, harmless, non-secondary pollution, sterilization rate are high and food is had to the advantage of fresh-keeping function.
