 Taida multi-pass biomass dryer is mainly used to dry and upgrade wood shavings, wood chips, wood powder, sawdust, bamboo shavings, little wood blocks. It is characterized by intelligence, energy conservation and environmental protection. Our multi-pass biomass drying line occupies less area, holds high output capacity and consumes less running cost. It can be used to dry biomass materials with 80% moisture content.   

【Input size】:  10-100mm

【Output capacity】:  0.5-100t/h

【Applicable materials】:

                        wood shavings, wood chips, wood powder, sawdust, bamboo shavings and other biomass raw materials.  

Product Introduction

      Multi-pass biomass dryer is mainly designed for wooden by-products, such as wood shavings, wood chips, wood powder, sawdust, crushed wood blocks, tree branch, leaves and other biomass raw materials. Based on continuous R&D, Taida multi-pass biomass dryer has achieved times technological upgrades. Present sold multi-pass biomass dryer is our third generation product featured by intelligence, energy conservation and environmental protection. At present, we have set many customer sites and enjoyed good fame at home and abroad. We also obtain great achievements in foreign market expanding. Taida has produced famous brand influence and set many project among major five continents.
      This series drying can be matched with continuous carbonization furnace and establish a carbonization production line. It can also work with pellet machine and establish biomass pellet fuel production line. By cooperation with plate processing equipment, compound plate production line can be established. Zhengzhou Taida Drying Equipment Co Ltd can supply various auxiliary machines in above production lines, like wood powder machine, screen machine, dryer, pellet machine, conveyor, packaging machine and dust collecting equipment. At present, with numerous working sites in England, Italy, Russia, Israel, Greek, Morocco, Australia, Malaysia, Laos, Sri Lanka, India and Chile, Taida influence become greater and greater. Our business has been expanded fast and gained superior achievements.

Working Principle

Multi-pass Biomass Drying Line

Structure advantage of Taida multi-pass biomass drying system
      Different from single-pass biomass dryer, new multi-pass biomass dryer adopts three-pass rotary drum which is also called three layer rotary drying structure. Main body of dryer is composed of several concentric circles with different diameters. This kind of structure can make full use of waste heat, reduce heat loss and increase heat exchange area Evaporation capacity in unit volume can be greatly improved. Correspondingly, heat value utilization rate can be raised. Compared with single pass dryer, thermal efficiency of multi-pass dryer can be increased by about 40% to 50%. More than one half energy consumption can be saved. Basic occupation area of multi-pass dryer is 65% smaller than single pass dryer. Occupation area cost and construction expense are pretty lower.
Taida new multi-pass biomass dryer working principle
      Considering from working principle, multi-pass biomass dryer belongs horizontal dryer. It mainly takes advantage of heat exchanging. Biomass raw materials will fully contact with hot air under function of dryer structure. Moisture will be evaporated in high temperature condition. Under the function of inner lifting plate, biomass materials will move to the other end while exchanging heat. Counter-flow drying process is carried out in the middle drum while raw materials will be lifted and driven forward repeatedly. Materials can absorb heat emitted from both middle drum and inner drum so that to reach to best drying effect. Materials will enter external drum after leaving end of middle drum. Materials will move in the state of rectangular multiloop state. Qualified materials will move rapidly under the function of hot air and discharged out of dryer drum. Unqualified materials cannot move forward fast owing to own weight. Materials will be fully dried in the rectangular lifting plate in order to finish drying aim.
