With the development of drying technology, the choice of heat source for distiller's grain dryer is more and more extensive. At present, there are a variety of heat sources to choose from in the drying market, such as natural gas, steam, biomass fuel, etc., so how to correctly choose the heat source of the distiller's grain dryer equipment? The following issues need to be paid attention to when selecting the heat source for the lees dryer.

1. Guarantee the dry quality of the lees

The drying quality of distiller's grains is closely related to the choice of heat source. Generally speaking, when drying distiller's grains, the fuel with good cleanliness and stability should be used as far as possible. Clean fuel avoids the possibility of material contamination, and the drying effect is good. The quality of the finished product directly determines the value of the material. Therefore, the selection of heat source should also consider the drying quality of the material. A clean fuel source can improve the entire dry production environment, which is beneficial to the increase of equipment output.

2. Pay attention to the environmental friendliness of fuels

In recent years, with the continuous introduction of environmental protection policies, coal, fuel and other polluting heat sources have been greatly restricted. The environmental protection heat source generates less waste heat in the drying process, and the waste gas treatment is relatively simple, and it is easy to meet the local environmental protection standards in the production process and protect the surrounding environment.

3. Adequate supply

The normal operation of the vinasse dryer requires a lot of fuel, which requires users to provide a large amount of fuel in time to effectively control the fuel cost. Therefore, users should consider the convenience and cost of fuel when choosing the heat source of the vinasse dryer, which is more conducive to the production of vinasse drying and the development of the enterprise.

4. Ensure the reliability of the heat source of the lees dryer

The stability and reliability of drying operation are basic issues that should be paid attention to in industrial production. Only in this way, the entire drying process can be carried out smoothly and orderly, and the appropriate heat source should be selected according to the flammable and explosive properties of the material.

5. Pay attention to the heating method

According to the different contact methods between hot air and materials, heating can be divided into direct heating and indirect heating. Flammable, explosive and fast-oxidizing fuels should be fully burnt and indirect heating should be used.

How to correctly choose the heat source of the lees dryer equipment? Most of the distiller's grain dryer equipment uses coal as the main heat source. When choosing the heat source of the distiller's grain dryer, we should consider the convenience of purchasing the heat source, try to adapt to local conditions, be easy to buy, and the price should be as low as possible, so that it will not affect the long-term heat source. It can also reduce the cost of long-term use of the heat source. The heat source must also meet the environmental protection requirements, and the heat source should have sufficient safety.
