Manioc waste residue drying device and device for manufacturing firewood bar and charcoal

Abstract

The invention discloses a cassava waste dregs drying device, a fuel rod making device and a charcoal making device. The drying device includes a sequentially connected throwing type pre-drying section, a front-stage gas-solid separation drying section and a rear-stage gas-material mixed hot air drying section; the front-stage gas-solid separation drying section includes a dryer with an interlayer , the inner cavity is fed into the material, and the interlayer is fed into the hot air; the material outlets of the front-stage gas-solid separation drying section and the rear-stage gas-material mixing hot air drying section are respectively connected with cyclone separators; The exhaust port of the separator is also connected with a dehumidifying blower. The drying device can dry the cassava wet slag produced in the production process of cassava starch with a moisture content as high as 70% even after mechanical dehydration into a dry slag with a moisture content of ≤ 15%. The dry slag is compressed and formed into fire rods and further fired into charcoal products, which have the advantages of low ash content, low sulfur content, high volatile matter and high calorific value, and are high-quality biomass energy.

Description

technical field [0001] The invention relates to a drying device, more specifically to a cassava waste residue drying device, and a cassava waste residue drying device and a charcoal making device using the drying device. Background technique [0002] Cassava, a shrub-like perennial crop, is widely cultivated in tropical regions of the world, and its roots are edible. The products produced and processed from cassava mainly include alcohol, starch, modified starch, starch sugar, organic acid, etc. Among them, starch is the most basic and important processed product of cassava. [0003] The current cassava starch processing and production generally includes several main processes such as raw material processing, soaking, crushing, separation, cleaning, and drying. The entire production process has problems such as low comprehensive utilization, short industrial chain, and lagging behind in the development of refined products. In particular, a large amount of waste residue pro...
