DEFOAMING METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain certain defoaming effect by performing defoaming action repeatedly by forming the foam circulating route going toward a defoaming part. SOLUTION: This defoaming method has a process for sucking foam from a stagnation part 12 to a defoaming part 13, a defoaming process for destroying or bursting the sucked foam in the defoaming part 13 and a process for forcibly guiding the foam which remains after passing through the defoaming process to the direction of the stagnation part 12 reverse to the direction at the time of suction. A convection comprising the suction and the guidance to the reverse direction is generated during the remaining period of foam and the defoaming process is repeated.
