Problems solved by technology

For a long time, chestnut bracts and shells have been treated as waste, which is not conducive to environmental protection, but also causes a waste of resources
[0003] On the other hand, in order to protect forest resources and the ecological environment, the production of charcoal using wood as raw material has been strictly restricted, and the supply of charcoal has been difficult to meet the growing industrial and agricultural production and the needs of people's daily life. gap

Embodiment 2

[0016] Example 2: The raw material is 100% of chestnut bracts, the moisture content is 46.8%, and the moisture content of the dried raw material is 18.9%. It is extruded into a cylindrical shape through an extrusion molding machine, and carbonized in a carbonization kiln. The carbonization temperature is 550°C 1. The carbonization time was 22 hours, and other processes were the same as in the previous embodiment. After carbonization, the solid carbon yield was 33.3% (the air-dry yield was 36.1%).

Abstract

A solid charcoal is prepared from the soft and hard shells of chestnut through pulverizing, drying die pressing and charring. Its advantages are high heat value and no pollution.

Description

technical field [0001] The invention relates to solid charcoal made from chestnut bracts and chestnut shells, which are wastes in the process of chestnut production and processing, and a preparation method thereof. Background technique [0002] Chestnut is a deciduous tree of Fagaceae, which is a unique fine dry fruit tree species in my country. Its fruit chestnut is wrapped by chestnut bracts and chestnut shells. Chestnut fruit must be removed from the bracts and shells during processing and consumption, so a large amount of waste-chestnut bracts and chestnut shells will be produced. For a long time, chestnut bracts and shells have been treated as waste, which is not conducive to environmental protection, but also causes a waste of resources. [0003] On the other hand, in order to protect forest resources and the ecological environment, the production of charcoal using wood as raw material has been strictly restricted, and the supply of charcoal has been difficult to meet...
