SECONDARY DIP PROCESSING DEVICE FOR FOOD TO BE BOILED

PURPOSE:To uniformly and sufficiently process food material to be boiled, by filling treating liquid in a secondary dip working tank in a suitable amount in proportion to the amount of water fed into the same tank from a water supply means so that the treating liquid sufficiently penetrates into the food at a predetermined concentration. CONSTITUTION:Testing and pH adjustment by use of condiments and organic acid are made simultaneously with secondary dip in a secondary dip section B. A rate filling valve 44 is disposed between a pump 43 in a hot water pipe line and a hot water tank 6 with a pipe line 42 being arranged on the main stream side. A treating liquid supply pipe line 45 is connected to the filling side of the rate filling valve 44. A pump 46 is also provided in a pipe line 55, and is driven, simultaneously with the operation of the pump 43 so as to feed treating liquid simultaneously with the supply of hot water. The filling amount of the treating liquid is set at a predetermined rate with respect to the supply amount of the hot water in accordance with the setting of a filling rate of the rate filling valve 44. With this arrangement, the treating concentration of the hot water 33 in the heating tank 6 is maintained at a constant value. This treating liquid 33 penetrates at a predetermined rates into secondary dipped rice 3 together with the hot water 33.
