Title: Screw-extruding dewatering-equipment and its operation method
Inventor: ISHIGAKI EIICHI
IPC: C02F11/12
Filed: 2002-10-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide batch press-in dewatering equipment for inorganic sludge in a small-scale water-purification plant, particularly aiming at improvement of function and space-saving.  <P>SOLUTION: A multi-ribbon spiral (12) is provided internally between an external-cylinder screen (1) and an internal-cylinder screen (6) placed in filtration equipment. While the screen (1) and the screen (6) are differentially rotated, a stock solution is forcibly fed in a filtration chamber (7) from an axial shaft (8) of the internal cylinder (8) in order to conduct solid/liquid separation. Sludge in the filtration chamber (7) is caked to complete the sludge press-in operation, and the cake is discharged by rotating the ribbon spiral (12) after a cake-discharge valve (21) of the chamber (7) is retracted. Scraping is conducted on the surface of the filer medium by the ribbon spiral (12). Thus, washing of the filter medium for each discharge of cake becomes unnecessary. Cake discharge is promoted by the ribbon spiral (12). While the screen (1) and the screen (6) are rotated together with the ribbon spiral (12), cleaning water is ejected to wash the whole surface of the filter medium.  <P>COPYRIGHT: (C)2004,JPO

Title: Method for producing purified lactide
Inventor: TANIGUCHI MASAAKI
IPC: C07D319/12
Filed: 2002-10-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for producing a purified lactide in high yield.  <P>SOLUTION: The method for producing the purified lactide comprises bringing a solidified material of crude lactide into contact with water, separating the solidified material into an aqueous phase and a solid phase, and recovering the solid phase. The method comprises a step of pulverizing the crude lactide, a step of mixing the solidified material with water and forming a slurry, and a step of separating the resultant slurry into a solid and a liquid. Since the crude lactide can be brought into contact with the water at a low temperature, the recovery ratio of the D-lactide or L-lactide is excellent. Since the surface area is extended by the pulverization, the removal ratio of the meso-lactide and a free acid into the aqueous phase is high. The purified lactide can be produced in high yield.  <P>COPYRIGHT: (C)2004,JPO
