PURPOSE: To automatically process agar such as a dice form by a constant amount without using manual operation.

CONSTITUTION: A charging tank 1 for boiling raw material agar, a filter 2 for filtering a boiled liquid, a cooling vessel 3 for cooling the filtrate, a storage tank 4 for storing the cooled filtrate, a liquid feeding pump 5 for feeding the filtrate by a constant amount, a forming pipe 6 for forming the filtrate into a jellylike semisolid and delivering the formed filtrate and a cutting and transferring means 7 for cutting the jellylike semisolid into a dice shape and delivering the cut semisolid are connectedly installed. Thereby, processing in which the raw material agar is processed into a jelly semisolid agar and cut into a dice shape, etc., is continuously carried out.
