specific Embodiment approach 1

[0010] Specific embodiment 1: The production process of potato residue fuel rods in this embodiment is carried out according to the following steps: 1. Add polyacrylamide to the potato residue and stir for 3-10 minutes, and then use a belt filter press to squeeze and dehydrate the potato residue , Get the potato residue filter cake with a mass moisture content of 65% to 80%; 2. Air-dry the potato residue filter cake, the stack height of the potato residue filter cake is 0.2-0.8m, and the frequency of stacking is 1 to 5 times during the drying process / Day, the drying period is 6-16 days, and the potato residue A with the mass moisture content of 50%-60% is obtained; 3. Mix the potato residue A with the potato residue filter cake obtained in step 1 at a mass ratio of 0.3-2:1 , And then air-dried to get the potato residue A with a mass moisture content of 50%-60%, repeat step 3; 4. Use a drum dryer to dry the potato residue A, the hot air temperature is 600-800 ℃, to obtain the ma...

Abstract

The invention relates to a production technology of a cassava-potato residue-made fuel rod. The production technology of the cassava-potato residue-made fuel rod mainly solves the problems that the existing fuel rod production technology has a high cost and cassava-potato residues obtained by starch production adopting raw materials of cassava and potato are discharged and then can cause environmental pollution. The production technology of the cassava-potato residue-made fuel rod comprises the following steps of 1, adding polyacrylamide into cassava-potato residues, and carrying out extrusion dehydration to obtain cassava-potato residue filter cakes, 2, carrying out airing drying of the cassava-potato residue filter cakes to obtain cassava-potato residues A having water content of 50 to 60%, mixing the cassava-potato residues A and the cassava-potato residue filter cakes, and carrying out airing drying to obtain the cassava-potato residues A having water content of 50 to 60%, 3, drying the cassava-potato residues A obtained by the step 2, and mixing the dried cassava-potato residues A and the aired cassava-potato residues A obtained by the step 2 to obtain mixed cassava-potato residues, and 4, crushing the mixed cassava-potato residues, and carrying out extrusion molding to obtain the cassava-potato residue-made fuel rod. The production technology provided by the invention realizes waste utilization, reduces environmental pollution caused by cassava-potato residue discharge, reduces a production cost, and is suitable for fuel rod production.

Description

Technical field [0001] The invention relates to a production process of potato residue fuel rods. Background technique [0002] Waste potato residue is the waste material left over from the production of cassava and potato starch. It has a high content of crude lignocellulose, a small amount of starch and crude protein, and a moisture content of more than 85%. Crude fiber has strong stability, low biodegradation efficiency, and difficult handling. As the demand and output of potato starch products continue to increase, the product attachments-potato residues that have not been processed in time have also increased significantly. These high-moisture wastes will not only cause greater pollution to the environment; the wastewater will also It will cause greater damage to vegetation and soil, and the odor generated during the decay process will pollute the atmosphere, which will further bring health risks to humans and animals. Due to the low protein content and high crude fiber co...
