    Abstract: PURPOSE:To carry out liquefaction and saccharification of starch in a series of processes to thereby facilitate the saccharification, by putting a starch emulsion obtd. by adding water to starch in a pressure vessel and heating it by microwave heating. CONSTITUTION:Starch 2 is put in a pressure vessel 1 and distilled water is added thereto. The vessel is degassed, sealed, and is placed in a microwave oven and irradiated with microwaves 3 to elevate rapidly the temp. and to keep the temp. in the range of 190-240 deg.C. The whole mass is thereby solubilized and a saccharified soln. is directly obtd. from the raw material starch emulsion. The liquefaction and saccharification can be carried out in a series of process by said procedures. Only water is used as the solvent and the soln. after the saccharification can be easily handled. Moreover, the disposal of waste is unnecessary.

    Abstract: PURPOSE:To obtain the titled starch product useful as ingredients for 'KANTONI', 'SUKIYAKI' or the like, by feeding fully gelatinized starch to a mesh conveyor belt to form a sheet of the feed thereon and passing it through a cooking room, a curing room, a cooling room, a hanging room, a quick-freezing room, a thawing room and a dewatering room. CONSTITUTION:A fully gelatinized starch is fed from a feed inlet 2 to a mesh conveyor belt 1 within a cooking room A to form a sheet 3 on the belt, moved in the direction of the arrow and sent to a belt 11 within a curing room B by a connection conveyor S. Hot water 4 in such an amount that the sheet 3 can be wetted is recirculated through cooking room A and curing rooms B 1-9 by means of a hot water inlet 6 and exits 5 and 15 to cure the sheet 3. This sheet 3 is cooled in cooling rooms C 1-2 kept at about 10 deg.C and about 5 deg.C, respectively, hung in a hanging room (each in a length of 60-100cm), passed through a quick-freezing room at about -15 deg.C over a period of 1-2hr, thawed in a thawing room by spraying with a shower 21 at about 30 deg.C and dewatered by passing through a dewatering room G in which press rolls of different gauge pressures are arranged. In this way, a half-cooked starch product of a water content of 23-80% is obtained.
