A 4-ton internal heating vessel was constracted in which soy-bean paste was heated by passage of an electric current directly from the commercial source. The temperature of the soybean paste was measured by thermocouple at several places. After heating, the temperature of the soybean paste near the vessele wall (especially the surface) was lower than in other parts owing to heat transfer to the vessel wall and to the atomosphere.This paper describes the installation of accessory electrodes to heat the low-temperatuer areas through localized electric current. As a result, while the temperature of the paste at the centre of the 4-ton vessel was raised from 27℃ to 45℃ in 25 hr, that at the surface reached only 16℃ without the accessory electrodes, but 24℃ with the accessory electrodes. By altering the number and position of these electrodes, the temperature can to some degree be changed at wall. The heating conditions were as follows : the atmospheric temperature was 3.0℃, the surface area of the vessel was 2.5 m×1.0 m, it was covered with a sheet of vinyl, and the electric power was about 3.0 kW.
