Production method of machine-made charcoal

Abstract

The invention provides a production method of machine-made charcoal and relates to the technical field of charcoal processing. The machine-made charcoal is prepared from 90 parts by weight of sawdust, 15 parts by weight of bamboo powder, 20 parts by weight of levant cotton exocarp powder, 15 parts by weight of peanut shell powder, 20 parts by weight of corn straw powder, 25 parts by weight of Artemisia argyi powder, and 6 parts by weight of diatomite. The sawdust, bamboo powder, levant cotton exocarp powder, peanut shell powder, corn straw powder and Artemisia argyi powder have particle diameters of 0.5-0.8mm and are obtained by drying, crushing, centrifugation screening and rough impurity removal. The production method has a wide raw material selection range, a low preparation cost and simple and easy processes. The machine-made charcoal has good density and long combustion time, contains diatomite for improving raw material viscosity, can be molded easily, does not easily crack and has high product quality.

Description

technical field [0001] The invention relates to the technical field of charcoal processing, in particular to a production method of machine-made charcoal. Background technique [0002] Mechanism charcoal is also known as mechanism charcoal, salary stick, artificial charcoal, regenerated charcoal, smokeless clean charcoal, and stick charcoal has a wide range of raw materials, such as rice husk, peanut shell, cotton husk, corn cob, corn stalk, sorghum stalk, etc. The raw materials for producing stick charcoal are best sawdust, shavings, and bamboo chips. Because the mechanism charcoal is smokeless, odorless and non-toxic, it has been widely used for home heating and barbecue food; in the industrial field, it can be used as industrial raw materials and further processed into activated carbon, etc. Due to its high density, high calorific value, smokeless, odorless, pollution-free, non-explosive and flammable charcoal, it is an internationally recognized green product.

Problems solved by technology

The chemical components of cellulose and lignin used belong to the category of carbohydrates, and contain many hydrophilic groups at the molecular level, such as glucose, which constitutes its basic unit, and contain many hydroxyl groups. These hydrophilic groups are compatible with many water molecules. , in the extrusion process, if the temperature is too low, the lignin cannot be effectively softened to increase the viscosity, which is not conducive to high-pressure molding, and the water cannot be effectively discharged. The extruded fire rods are bent or not formed, which will affect the subsequent carbonization And the yield of fixed carbon; if the temperature is too high, the lignin will soften too quickly, the rod will be released quickly, and the fuel rod will not be strong, and the water will quickly evaporate into water vapor, leaving these hydrophilic groups, so that the fuel rod will burst , which is the form of strong dehydration of the salary rod. Burst or broken lines of the salary rod are not conducive to the later carbonization. At the same time, the extrusion temperature is too high, which also affects the cost of the product and the condition requirements for the molding machine.
