Amorphous silicon used in foods, pharmaceuticals, cosmetics and feeds, and production method and production apparatus thereof

摘要

Combustion treatment is one step, does not contain tar, crystallized substances, residual agricultural chemicals and carcinogenic substances, and is porous and easily soluble in water, amorphous silicon used for foods, pharmaceuticals, cosmetics, feeds, and its A manufacturing method and apparatus is obtained. While stirring rice husk etc. in a temperature range of 500 ° C. or higher and 700 ° C. or lower, the mass of 6.7 times or more and 20 times or less the weight of the rice husk etc. or the weight of the rice husk etc. In contrast, 1.4 to 4 times or less oxygen gas or a mixture of air and oxygen (mixing ratio is in the above-mentioned range) is introduced into the furnace and burned. Porous and easily soluble in water, free of tar, crystals, residual agricultural chemicals and carcinogens, which is obtained by means of exhausting some of the dry distillation gas from the furnace to obtain combustion products such as rice husks A method for producing amorphous silicon, characterized by producing silicon.
