It was mainly composed of Endless Held 5, which was transported as it was.

(Problems to be Solved by the Invention) However, in the conventional rotating cylindrical processing apparatus as described above, since the cooling or heating of the object to be processed 4 by the cylindrical body 1 depends on the rotational speed of the cylindrical body 1, In order to cool or heat the object 4 to a desired degree, the cylinder 1 must be rotated at a low speed, resulting in a low processing capacity.

To solve this problem, it is possible to make the cylindrical body larger, but increasing the size of the cylindrical body is extremely difficult due to manufacturing and installation problems, and it may not take much cooling or heating time. Since the time is not long, no improvement in processing power can be expected.

The purpose of the present invention was to solve the problems of the conventional process, and to provide a rotating cylindrical processing device that can process objects in a large size while cooling or heating them to an appropriate temperature. It is about providing.

(Means for Solving the Problems) A rotating cylindrical processing apparatus of the present invention includes two rotatable cylindrical bodies that are arranged adjacent to each other and can be cooled or heated, respectively, and an outer circumferential surface of the two cylindrical bodies. an endless heald wrapped around each part of the heald with the same side of the heald in contact with the
The cylindrical body is configured to include a supply section that supplies the object to be processed to the outer circumferential surface of one of the cylindrical bodies.
