Cassava residue dryer and dehydrator — cassava residue treatment equipment

Brief introduction of cassava dregs dryer

      Cassava residue is a kind of material which combines water and oil, so the water content is not easy to deal with. Moreover, the cassava dregs will form a mass when the concentration increases, which is very unfavorable to the evaporation of water. In view of this feature, our company has developed a complete set of equipment for drying cassava dregs.

      Cassava dregs enter into the dryer, and under the action of special pusher plate and dry hot air, they move back and forth in the direction opposite to the direction of fresh dry hot air. In this process, the agglomerated cassava dregs are broken by the rapidly rotating crushing axis, and the water molecules are fully evaporated by high hot air flow. In the whole drying process, the thermal energy is fully utilized, and the cassava residue is evenly heated, so the color of the dried cassava residue is good, there is no paste, and the energy consumption is low.

Mechanical structure and working principle of cassava residue dryer

      The cassava dregs dryer is mainly composed of heat supply, feeder, rotary drum, discharging machine, induced draft fan, unloader and power distribution cabinet; after entering the dryer, the cassava dregs are evenly distributed in the dryer and fully contact with hot air under the flip of the evenly distributed board in the drum, which accelerates the heat and mass transfer of drying. In the drying process, cassava dregs are discharged to another section of star discharge valve of the dryer to dry the finished products under the action of the inclined board and hot medium. The selection and design of process parameters, equipment technical parameters and structure of the production line are obtained after careful analysis and research of soybean dregs, and verified by the actual drying test of soybean dregs. In the scheme design, the characteristics of large moisture content, high protein content and high viscosity of soybean dregs are fully considered, and a series of unique unique technologies and processes are adopted to solve the problem, so as to ensure a good drying effect.

Mechanical structure and working principle of cassava residue dehydrator

1. The distribution area passes through the refined wet slag raw material (or solid mixture), and the slag slurry is leveled by a unique rotating mechanism, so that the slag slurry is evenly distributed on the lower filter screen. At the same time, most of the free water between fibers is removed.
2. The main components of the precompression area: three uniformly distributed slag slurry from the wedge-shaped area and the arc-shaped roll enter the arc-shaped area of the lower bend for initial pressure dehydration. The idler set in the three parabola further slowly applies soft pressure, and a part of the gap water is extruded.
3. Main components of low-pressure drainage area: porous drainage roll is composed of a super large diameter drainage roll evenly distributed with 6048 drainage holes, a large area of low-pressure drainage area, and a unique drainage structure, which can quickly drain the pressing water, and the Super Large Diameter Drainage roll can ensure that the pressing force is soft and improved.
4. 5. 6. The upper and lower filter belts in the extrusion zone I ~ III in the high pressure zone bypass three groups of counter pressure rollers with decreasing diameter, so that a large amount of water is forced out slowly and forcefully, forming filter cake. At the same time, the “s” type winding of the filter belt produces increasing surface shear force. Under the effect of the tension of the filter belt, the outer filter belt produces pressure on the slag slurry to squeeze out a small amount of water in the slag slurry. As the diameter of the counter pressure roller decreases gradually, the pressure on the slag slurry between the filter belts increases gradually, and a small amount of water is discharged continuously, which makes the water in the slag slurry decrease gradually.
