Refrigerator door [preferred] Shandong Huayu freezing cold mainly used for food processing and refrigerated cold storage doors, through artificial refrigeration Weihai refrigerator door, the room to maintain a certain low temperature. Cold walls, floors and laying flat top are a certain thickness of insulating material, in order to reduce the external incoming heat. In order to reduce the absorption of solar radiation, the cold exterior wall surface is generally painted white or light colored. So cold and general industrial and civil construction is different, has its unique structure. Cold storage building to prevent diffusion of water vapor and air penetration. Outdoor air not only increases the consumption of cold cold invasion, but also to the Treasury into the water, moisture condensation caused structural insulated building structures, especially damp freeze damage, so to set the moisture insulation, cold storage building so good tightness and moisture vapor barrier properties. Ground affected low temperature cold storage, soil moisture is easily frozen. Volume expansion due to the freezing of the soil, ground rupture and cause deformation of the entire building structure refrigerator door manufacturer, severe cold will not be used. To this end electric refrigerator door, cold storage floor except to have effective insulation layer, the lower insulating layer must be treated to prevent the soil from freezing. Refrigerator door [preferred] Shandong Huayu maintain cold: cold sterilization and disinfection addition to mold cold refrigerated cooking ingredients and food have contain some fat, protein and starch. The presence of these nutrients, causes the growth of mold and bacteria multiply. To do cold She health management work to ensure the quality of food and cooking frozen raw, cold She would periodically sanitation and disinfection work. In addition to killing mold and mildew cold sterilization, to use acid disinfectant. Acids disinfectant sterilization, primarily solidified bacterial proteins. Common disinfectants have lactic acid, peracetic acid has, bleach, formalin. Electric refrigerator door | Fitch machinery (certified) | refrigerator door by Fitch Machinery Co., Ltd. Shandong.
