• The self-insulation thermal efficiency of the cylinder can reach more than 70% (the traditional single cylinder drying thermal efficiency is only 30%).
• The rear transmission is adopted, which makes the transmission more stable and reliable; Completely change the rotation of the supporting wheel, which often slips and affects the production.
• The land occupation is reduced by about 50% compared with that of single drum dryer, the civil construction investment is reduced by about 50%, and the power consumption is reduced by 60%.
• The combined distribution of various circumferential lifting materials can effectively control the drying time, and the drying effect is good.
• The final moisture index can be easily adjusted according to user requirements.
General description of Wood Shavings Dryer:
The woodchips dryer produced by our company is composed of three concentric cylinders with different diameters, which are embedded and combined with each other according to a certain mathematical relationship and structural form. It is widely used in biomass, non-metallic mining, chemical industry, environmental protection, feed, agriculture, forestry and other industries. It is specially used for drying such dregs as sawdust, sawdust, straw, shavings, bark, wood flour, rice husk, pasture, oil palm silk, plant fiber, brewer's grains, cassava dregs, ginkgo leaves, marigold, Chinese herbal medicine, alfalfa powder, corn cob, vegetable powder, various crystals, non-metallic mineral powder, inorganic fertilizers, etc. Hot air can be reused according to user conditions, with thermal efficiency up to 80%, which is significantly higher than similar drying equipment.
Working principle of Wood Shavings Dryer:
High temperature hot air and wet materials enter the central cylinder together, then rotate, flow along the middle annular channel, rotate again, and pass through the outer annular channel to the outlet of the drying cylinder. The materials in each channel are transported under high temperature air flow pressure and dried in suspension. There are also blades in the channel to carry the scattered materials. The tiny particles pass through the dryer almost at the same speed as the air flow. The wet and heavy materials in the middle and outer annular channels fall from the material flow, but because the rotation of the drying cylinder is carried by the blade again, they return to the air flow and are constantly surrounded by the drying medium.
Under the action of this movement, the smaller particles can be dried quickly and discharged from the drying cylinder quickly. The wet bulk crushed materials stay in the drying cylinder for a long time. This will make the drying of materials more uniform. When hot air flows with materials, strong heat and mass exchange will occur. At the outlet of drying cylinder, the temperature of drying medium will drop to 80-120 ° C.
Main features of Wood Shavings Dryer:
• The self-insulation thermal efficiency of the cylinder can reach more than 70% (the traditional single cylinder drying thermal efficiency is only 30%).
• The rear transmission is adopted, which makes the transmission more stable and reliable; Completely change the rotation of the supporting wheel, which often slips and affects the production.
• The land occupation is reduced by about 50% compared with that of single drum dryer, the civil construction investment is reduced by about 50%, and the power consumption is reduced by 60%.
• The combined distribution of various circumferential lifting materials can effectively control the drying time, and the drying effect is good.
• The final moisture index can be easily adjusted according to user requirements.
• Variable frequency speed regulation is adopted to control the material flow, and the required final moisture index can be easily adjusted according to the user's needs.
• The whole system is equipped with material blocking alarm and anti-riot device.
Application of Wood Shavings Dryer:
Based on the three drum dryer, combined with years of industry experience and engineering examples, a variety of special dryers can be provided. Such as sawdust dryer, sawdust dryer, cassava residue dryer, shavings dryer, wood flour dryer, medium grass dryer, fiber dryer, rice hull dryer, straw dryer, beer trough dryer, marigold dryer, forage dryer, alfalfa grass dryer, oil palm fiber dryer, mineral powder dryer, etc.
