Four common methods of rose microwave drying equipment materials

How many kinds of common materials are used in Rose microwave drying equipment? Let's look at the following: 1 To meet the needs of the processed materials, the main task of rose microwave drying equipment is to dry the given materials Due to the wide variety of materials processed by the dryer, it covers many fields such as grain, food, pharmacy, chemical industry, forest products, paper, metallurgy, etc., and the products are even more difficult to count The requirements for dried materials vary greatly, such as chemical reagents, drugs, electronic materials, electrical and ceramic materials, etc iron ions must not be mixed in the drying process, so carbon steel materials should be avoided in the selection of equipment materials In addition, if the moisture in the material contains acid, alkali, salt, organic solvent, etc., it will be corrosive to different metal materials Especially in the process of heating, the corrosion of materials will be intensified, so the appropriate materials should be selected according to the characteristics of moisture content in materials 2 In many cases, although the above conditions can meet the requirements, we should pay attention to the material requirements of the equipment installation environment If the equipment is installed in the chemical plant, the environment should seriously consider whether the equipment, control system and electrical system are corrosive 3 According to the different drying conditions of materials selected in the drying process, the author has designed a high-temperature dryer, which can dry inorganic salt and polymerize it at the same time It is required that the temperature of drying hot air is above 800 ℃, and the drying materials have to choose high temperature resistant stainless steel with low price However, considering that the drying rooms are not all in the high temperature area, according to the calculation, only the high temperature resistant materials are selected in the high temperature area, which has been running normally for more than one year 4 The selection of materials for Rose microwave drying equipment mentioned before, there are many types of dryers, and the working principles of each type are different, so the selection of materials should also be fully considered For example, when drying magnesium oxide in the air dryer, because of the high speed of the material in the air flow pipe, the magnesium oxide material is hard, and the turning wall of the drying pipe is seriously worn, so in this area, it is necessary to design the anti-wear structure or select the wear-resistant material For example, compared with carbon steel, the thermal conductivity of stainless steel is significantly lower than the former Therefore, if stainless steel is selected as the main material in the microwave drying equipment, the heat transfer area of the equipment should be calculated by the thermal conductivity of stainless steel The engineering example shows that the area of stainless steel is 30% larger than that of carbon steel when selecting steam heat exchanger The above four methods are common for Rose microwave drying equipment materials
