Product Introduction
The market demand has developed the paddle-mixed rotary drum dryer, also known as the rake drum dryer, the rotary rake drum dryer, and the rotary paddle drum dryer. Based on the advantages of the tumble dryer, in view of its inability to adapt to the drying of weakly cohesive and cohesive materials with moisture greater than 50%, and the "black hole" phenomenon in the center of the drum, it has low evaporation capacity per unit area and high fuel consumption. The agitating high-speed rotating blade is added to strengthen the crushing and dispersing function of the material, filling the "black hole" in the center of the drum, the surface area of the material is fully expanded, and the material is fully contacted with the hot air to transfer heat and evaporate the moisture of the material. The speed is greatly improved. The large-area production practice has proved that the paddle-stirred rotary drum dryer has a water evaporation capacity of 25-60 kg water/m2·h per unit area than ordinary drum dryers, which is 1-2 times that of ordinary drum dryers. The capacity of the size dryer is increased by more than 50%, the fuel energy consumption is reduced by more than 30%, the equipment area is more than 40% smaller, the moisture of the dried material is more uniform, and the efficiency is increased by more than 40%. It is suitable for drying all kinds of medium and low moisture materials such as wood chips, sawdust, bamboo chips, etc., especially suitable for beer lees, white wine lees, bean dregs, starch residue, sauce residue, sprayed corn husk, cassava residue, straw, pasture, organic fertilizer, chicken Drying of high-humidity materials with a moisture content of 50-65% such as cow manure and sludge. Our company optimizes the drying process technology design according to the characteristics of each biomass material, the output size, application requirements, cost control, automation degree, and on-site working conditions.
According to the market demand, the paddle-stirring rotary drum dryer has been developed, also known as the rake drum dryer, the rotary rake drum dryer, and the rotary paddle drum dryer. On the basis of the advantages of ordinary drum dryers, it is not suitable for the drying of weakly bonded and cohesive materials with moisture greater than 50% and because of the drum center "
The phenomenon of "black hole" makes its unit area low evaporation capacity and high fuel energy consumption. The agitating high-speed rotating blade is added to strengthen the crushing and dispersing function of the material, filling the "black hole" in the center of the drum, and the surface area of the material is fully expanded, and it is fully compatible with the hot air. Contact heat transfer to evaporate the material moisture, because the material particles are smaller, the heat transfer evaporating moisture speed is greatly increased. Suitable for wood chips
, Sawdust, bamboo shavings and other low- and medium-moisture materials, especially suitable for sludge, bean dregs, starch residue, sauce residue, sprayed corn husk, cassava residue, beer lees, liquor lees, straw, pasture, organic fertilizer, chicken Drying of high-humidity materials with a moisture content of 50-85% such as cow dung. The company can according to the characteristics of each biomass material, output size, application requirements, cost control, automation process
Optimize the design of drying process technology for temperature and on-site working conditions.
working principle
The material flow is: about 50-85% of the water content is sent from the screw conveyor to the mixing drum dryer to achieve downstream drying. The material is continuously picked up and scattered under the copy board in a spiral progression. The built-in mixing paddle device will The material is fully stirred and broken, the material and the hot air are fully exchanged in quality and heat, and the water evaporates quickly. The material that achieves the drying effect is fast under the action of the hot air.
The wet material that has not reached the drying effect can not travel quickly due to its own weight. The material is fully dried in the drum, thereby achieving the drying effect, completing the drying process, and being discharged by the screw conveyor. A shock cleaning device is installed inside the drum to prevent the material from adhering to the wall of the drum.
