多大の利点がある。[Effects of the Invention] As is clear from the above, according to the present invention, when indirectly heating a highly viscous liquid, the indirect heating device has a fixed stirring mechanism (liii) in the liquid circulation path. In this method, a plurality of twisted plate members are arranged in series in the axial direction, and the plate members are arranged out of phase with each other, so that the liquid flowing under pressure into the passage is twisted by the plate members, and the phase of the liquid downstream is shifted. Therefore, the liquid does not become a laminar flow, and the outer layer, middle layer, and inner layer are agitated without any speed, and are in contact with the inner wall of the inner cylinder that forms the passage. The liquid can be moved and heated through efficient heat exchange.
Efficient indirect heating can be achieved evenly in each part without burning, and the above can be done by simply installing twisted plate-like members in the pipe-like inner cylinder in a row in the axial direction with different phases. Therefore, it has many advantages such as the above-mentioned revolutionary advantages with a simple structure.
