Haomai drying reminds you to choose the heat source of dryer, which directly affects the drying and wetting degree of materials.

The drying capacity of the dryer is related to the drying degree of materials, the selection of heat source and the heating area of materials in the dryer. If the drying of high humidity materials is not enough, the dried materials will be slightly moist. It is also very important to select heat sources for different materials. Insufficient heating area and uneven heating will also affect the drying effect of materials.

The selection of heat source of dryer is very particular. There are many heat source equipment matched with drying equipment, which are usually classified according to the fuel consumption, including coal, fuel oil, gas and electricity. According to the heat exchange situation, it can be divided into direct heating and indirect heating of drying medium.

According to different heating methods, the common heat source equipment of dryer is as follows:

For example, the boiler heats water to form steam, and the steam then heats the drying medium through the radiator. This is two indirect heating, and the total thermal efficiency is very low.

Secondly, the dryer uses coal-fired hot blast stove, which has indirect heating and direct combustion flue gas as drying medium (direct furnace). The indirect heated hot air is clean and clean, and the thermal efficiency is 60-70%. However, the product quality is affected by the pollution of smoke and dust, but the heat energy is fully utilized and the thermal efficiency is very high. When a small amount of smoke and dust is mixed into the materials when the dryer is drying, it can be used preferentially.

After that, the dryer uses an oil burner. It has the advantages of simple operation, rapid heating, stable temperature, convenient control, and low cost.

The reasonable selection of heat source of dryer has a great influence, which involves the investment cost of dryer equipment, hot air temperature, drying quality of materials, drying cost, environmental protection, labor intensity of personnel, automatic control level, etc. If the material is too wet when entering the dryer, it is not conducive to the control of heat. It is easy to cause the material to be quickly heated and damage the drying effect of the dryer. The material is massive, or the ventilation effect is not good.
