Abstract
A main energizing/heating unit has an outer electrode and an inner electrode, and energizes a fool material to be gelatinized by heating and continuously heat-treats it while it is conveyed in a food flow channel. The food flow channel in which the food material flows is formed between the both electrodes. Fed to the food material flowing in the food flow channel by a power supply section is a current in a direction traversing a flow direction of the food material. An inner cooling flow channel is formed in the inner electrode, and cooling liquid is fed to the inner cooling flow channel through a piping.
Claims14
A continuous heat-treating apparatus for food material, the apparatus heating a liquid food material to be gelatinized by the heating, the apparatus comprising:
- a main energizing/heating unit,
- wherein the main energizing/heating unit includes:
- a cylindrically-shaped outer electrode;
- a bar-shaped inner electrode placed inside the outer electrode, a food flow channel in which the food material flows being formed between the outer and inner electrodes;
- a power supply section feeding power to the outer and inner electrodes, and energizing the food material, which flows in the food flow channel, in a direction traversing a flow direction of the food material;
- and
- a piping feeding cooling liquid to an inner cooling flow channel, the inner cooling flow channel being formed in the inner electrode, and
- the food material is heated while the inner electrode is cooled.
An energizing and heating method of heating a food material to be gelatinized by the heating while the food material is conveyed in a food flow channel formed between a cylindrically-shaped outer electrode and a bar-shaped inner electrode placed in the outer electrode, the method comprising:
- feeding power to the outer and inner electrodes to energize, in a direction traversing a flow direction of the food material, the food material flowing in the food flow channel;
- feeding cooling liquid to an inner cooling flow channel formed in the inner electrode;
- and
- cooling the food material close to the inner electrode up to temperature lower than that of the food material close to a center of the food flow channel.
