Title:
ケイ酸含有粉末製造方法およびケイ酸含有粉末製造システム
Document Type and Number:
Japanese Patent JP3579417
Kind Code:
B1
Abstract:
It is intended to provide a method of producing a silicic acid-containing powder and a system for producing a silicic acid-containing powder whereby rice hulls and straws are treated within a short time at a low cost without decreasing silicic acid and thus a powder containing natural silicic acid conveniently usable as a straight fertilizer can be produced. The above object is achieved by a method of producing a silicic acid-containing powder from rice hulls or straws which comprises jetting high-pressure steam into rice hulls or straws fed into a treatment container (2) and then powdering the contents while maintaining the pressure in the treatment container (2) at 1.45 MPa to 1.96 MPa.
