Improvements in the production of biogenetic silica from organic plant matter

摘要

In a method for the production of biogenetic silica from organic plant matter, the plant matter is fed continuously by a screw conveyor (13) from a hopper (12) to a furnace in the form of an inclined tube (11) which is maintained at a temperature of about 450 DEG and rotated at a speed of about 1 rpm. The material travels down the inclined tube and is retained in the furnace for no more than about 30 minutes. Biogenetic silica is collected from the lower end of the tube (11) in a collection can (18) and is allowed to cool. The inclined tube (11) may be mounted on a wheeled platform (19) so that the furnace is portable.
