Refining method and refining device for separating unnecessary matters from articles

摘要

Provided are a refining method and device in which articles, especially bean sprouts-like articles can be sufficiently applied with refining actions by a simple structure. The refining device for such articles comprises a refining water tank (30) comprising a water storage tank (40) provided with an overflow draining portion (41) and a refining vessel (50) provided in the water storage tank (40) with an interval maintained from an inner surface of the water storage tank (40) and having its bottom portion and side portion at least at one place thereof formed with a multi-hole portion (51). The refining device also comprises a dispersing supply device (5) for supplying the articles to be refined in a dispersed state into the refining water tank (30) and a water supply device (70) supplying feed water obliquely from above into the refining water tank (30). The water supply device (70) is so constructed that supply angle of the feed water can be changed around a pin (73).
