Choosing a good heat source for the bean dregs and yeast dryer can not only ensure the drying effect of the material, but also reduce the production cost of the enterprise and achieve the purpose of energy saving and environmental protection. The heat sources that can be used as bean dregs and yeast dryers in the market include coal, oil, gas, electricity, biomass fuel, industrial waste heat, etc. Faced with such a large range, how should users choose the heat source of the bean dregs and yeast dryer? What principles should be followed for the selection of heat sources?

1. Environmental protection

Focusing on the level of "green environmental protection", the state has successively issued a series of standards to restrict exhaust emissions. However, some heat sources will produce harmful gases such as sulfur dioxide, carbon monoxide, and soot when they are burned. If they are directly discharged into the atmosphere, they will pollute the air. Therefore, users should choose environmentally friendly energy when choosing the heat source of the bean dregs and yeast dryer. Under the condition that the heat source can be fully burned, the emission of sulfur dioxide, carbon monoxide, high-temperature flue gas and soot should be minimized to reduce environmental pollution.

2. Economy

The economy of heat source is mainly reflected in: ensuring that the heat source is easy to obtain, and avoiding the lack of heat source affecting the normal operation of the equipment. Input cost of heat source, including purchase cost, transportation cost, production cost, etc. Higher economic benefits can be achieved by reducing the input cost of the heat source.

3. Controllability

For drying different materials, the required drying temperature is different. The user is required to reasonably control the heat supply of the heat source in the production process, which can not only ensure the quality requirements of the dried materials, but also ensure the stability of the equipment.

4. Security and reliability

Some materials contain some flammable, explosive and oxidizing substances. Once the drying temperature is too high, the material will be flammable, explosive and oxidized. Therefore, when drying these materials, it is necessary to select a safe heat source or control the temperature of the heat source to ensure the normal operation of the bean dregs and yeast dryer equipment.
