How to disinfect and sterilize the cold storage?

1, sulfur disinfection method: this is the most traditional disinfection method, has been used for many years, is in the library of industrial sulfur and sawdust mixed ignition, and then closed 12-24 hours after ventilation exhaust. This disinfection method is simple and easy to implement the cost is not high, but the side effects are very great, after the disinfection of acidic substances on the fruit and vegetable storage racks, wind barrels, evaporators have a strong corrosive, rust on their surfaces, reducing the safety of the use of the facility, the continuous use of this disinfection of the cold storage may be inverted racks, leakage of ammonia and other phenomena to the storage of households to cause greater losses, so the use of sulfur disinfection of the cold storage method does more harm than good.
2, formaldehyde potassium permanganate method: formaldehyde and potassium permanganate fumigation disinfection, and then closed for 48 hours and then ventilated exhaust disinfection method, this method also plays a better effect of disinfection of the warehouse, but the gas produced by the human stimulation is very large, the warehouse fumigation for a long time after the difficult to exclude irritating gases, a direct impact of the progress of the fruit and vegetable into the warehouse in the time and cost of bad control, if the time to extend the exhaust time, it is easy to lead to the warehouse outside some of the The entry of germs, resulting in incomplete disinfection of the library.
3, ozone disinfection: ozone’s powerful bactericidal ability to inhibit the growth of mold, effective mold. But the ozone equipment investment, the cost is higher than other disinfection methods, the main disinfection of the pipeline has a corrosive effect on the mucous membranes of the human respiratory tract has stimulation.
4, ultraviolet disinfection: the combination of ultraviolet light cold storage disinfection method is a better method it can not only sterilization, but also in addition to mold. But ultraviolet disinfection without continuous sterilization ability, disinfection of water if encountered new sources of pollution, will be contaminated again, turbidity and suspended solids in the water on the ultraviolet sterilization has a greater impact on reducing the disinfection effect.
