Its role is to slow down the flow of high temperature materials, reduce the heat transfer rate, reduce the temperature of the front end of the dryer. This drying can be applied to wood drying, because the principle of drying equipment is the same. Large drum dryer low temperature drying with L hanging plate about 1/3 of the length of the cylinder.
Tilt place due to the dryer, material in gravity and turning back end on one hand, on the other hand oblique placement, materials in gravity and turning back end on one hand, and turning back side material copied board repeatedly grabbed, make the material inside the drum materials was repeatedly copied copy board, to the top again constantly raise and down, to the top again constantly raise and down, form a uniform curtain, Fully heat exchange with the hot air flow in the cylinder, forming a uniform curtain, fully heat exchange with the hot air flow in the cylinder, because the material is repeatedly scattered, the moisture contained in the cylinder is gradually dried, and the compound scattered, the moisture contained in the cylinder is gradually dried, so as to achieve the purpose of drying.
If the raw materials are not allowed to be polluted by the environment and the temperature is high, a new type of gas producer can be used as heat carrier. This product is energy saving, environmental protection and high thermal efficiency. If the local energy conservation and environmental protection requirements are very high, and want to save energy, health gas producer will be a better choice. The gas producer in the energy saving level than the combustion furnace at least 20% energy saving, in the artificial also greatly saves a lot of, usually the gas producer has a work can operate, and do not need to keep adding coal, in addition to the gas producer can stop with the use, up to 10 days do not work, the next can continue to use.
