Plant source herb residual machine-made carbon and method of processing the same

Abstract

The invention discloses botanical herb residue machine-made charcoal, which is machine-made charcoal prepared from residue of botanical Chinese medicinal herbs, sasanqua and kiskatom fruit peels after extraction of effective constituents, and auxiliary materials through mixing, blank compaction, drying and carbonization, wherein the machine-made charcoal comprises 55 to 85 weight percent of botanical herb residue and 15 to 45 weight percent of auxiliary materials, and the auxiliary materials are selected from crushed pine branches and/or redwood branches and/or mulberry branches and/or bamboo chips. A blank is extruded into a blank with through holes under the conditions that the temperature is more than or equal to 200 DEG C and the pressure is more than or equal to 3kg/cm; and the blank with the through holes is dried until the water content is less than or equal to 15 percent and then is sent into a carburization furnace for dry distillation carburization. The machine-made charcoal has the advantages of black appearance, smooth surface, uniform dimensions, high strength and high calorific value, is favored by foreign businessmen, and has been exported to Japan in batches.

Description

1. Technical field [0001] The invention relates to a machine-made charcoal and a preparation method thereof, in particular to a machine-made charcoal from plant-derived medicine dregs and a processing method thereof. 2. Background technology [0002] my country is a big country in the production and use of charcoal. The annual demand for charcoal in chemical industry, metallurgy and food processing alone reaches 12 million tons, and the export of charcoal also reaches more than several million tons. National statistics show that the annual crop residues are 6 to 7 billion tons, the utilization rate is 20%, and 80% is rotted and discarded. Although with the implementation of the national natural forest protection project, the production and export of charcoal are restricted, but its demand is still increasing year by year, the supply exceeds demand, and the contradiction between supply and demand is prominent. In view of this, people use agricultural and forestry processing ...

AI Technical Summary

Problems solved by technology

At present, most of the raw materials for domestic machine-made charcoal production are sawdust, wood shavings, wood chips, bamboo chips, and urban sanitary organic matter. Not only are the sources of raw materials insufficient, but also the cost is high.
