Introduction of biomass drum dryer
The biomass drum dryer is suitable for drying of wood chips, sawdust, bamboo shavings, wood chipper, wood shavings, barley straw, oat straw, wheat straw, rye straw, rice straw, sorghum straw and corn stalks and potato vines, beans stalk (including materials like soybean straw, broad bean straw, pea straw, cowpea straw, lupine straw, peanut vine, etc.).
Working principle of biomass drum dryer
The material goes through the feeding device into the lining of the rotary drum, in order to realize the downstream drying, material inner constantly grabbed, scattered under the copy board of a spiral rolling to realize heat exchange, the material moves to the other side of the lining and into the middle side, at this time going counter flow drying, material in the middle is constantly repeated by copy board, it is marching into two steps forward and one back, material in the middle fully absorb heat coming from the inner cylinder, and absorb the middle roller heat and prolong the drying time again at the same time, at the moment dry material is at the best condition.
The material goes to the other side of the middle section and into the outer section, material within the outer cylinder in rectangular loop travel , in order to achieve the material moving fast to discharge roller under the effect of drying in hot air. Because of the weight other wet material can't advance rapidly drying, the material returns to this rectangular copy board with fully drying action, in this way it can achieve purpose of drying.
Characteristics of biomass drum dryer
- Automatic control, the biomass drum dryer can ensure that the drying of sawdust moisture is uniform and stable.
- Removing stones and iron automatically can ensure that they will not enter into next process.
- Heat efficiency reaches up to 70% (the heat efficiency of traditional single drum dryer is only 35%), which improves the heat efficiency by 50% at least.
- Adopts rear transmission, makes the transmission more stable and reliable, revolutionized slip phenomenon of wheel rotation which will affect the production.
- Compared with single drum dryer, it reduces floor space by 50%, decreases civil engineering investments by 50%, and more energy-saving.
- A combination and distribution of a variety lifting way for materials, effective regulation the drying time, good drying effect.
- Our biomass drum dryer can easily control the desired final moisture indicators according to the customers’ requirement.
- Using frequency regulating speed control system to control the material flow, can easily control the desired final moisture indicators according to users’ needs.
- Air outlet temperature is low, dust removal equipment can be used for a long time, continuous start the next process.
- It can be matched with a new type hot blast stove, high efficiency and energy saving, thermal control and easy operation. The energy consumption decline reaches up to 30%, power consumption decreases by 20%, the operating cost is lower.
