How to process a large amount of waste residue from the processing of the corn starch factory? At present, corn starch residue can be used as feed. Today, I will introduce the main process of corn starch residue drying treatment.
The corn starch residue with relatively large water content can be dehydrated by Dingli extrusion dewatering equipment, and the moisture is removed to a certain extent. The screw conveyor is fed into the mixing drum dryer to achieve downstream drying, and the material is continuously picked up under the copying board. The scattered spiral advancement, the built-in stirring paddle device fully stirs and breaks up the material, fully expands the heat exchange area between the material and the hot gas, and the material and the hot gas are fully heat exchanged, and the water is quickly evaporated and vaporized to reach about 35%. The drying process is discharged by a screw conveyor and enters a special pulverizer for semi-wet materials. The granulated material has a particle size of less than 1 mm and enters the pulse airflow drying process. The material rapidly drops below 10%, and the dust is discharged by the cyclone unloader and the pulse bag. The dry powder is recovered, the exhaust gas is discharged to the standard, and the entire drying process is completed. A shock cleaning device is installed inside the drum to prevent the material from adhering to the cylinder wall.
The dried corn starch residue can be used as a feed material. The treatment in this way can solve the problem of starch starch treatment in the starch factory. At the same time, the waste can be reused to create secondary income, so customers with resources can dry it and use it.
