It resides in the processing device.

[0006] An example of the device of the present invention will be described in more detail below using the drawings. The apparatus shown in FIG. 1 is a cooling apparatus for thermoplastic synthetic resin in a synthetic resin manufacturing process, and is an example of an application of the apparatus of the present invention. FIG. 1 is a schematic explanatory diagram of an example of the apparatus of the present invention. In the figure, 1 is a rotating cylindrical processing device, 2 is a processing object supply section, 3 is a processing object, 4 is a cylindrical body, 5 is a rolling roll, 6 is a cooling or heating mechanism, 7 is an endless belt, 8, 8' , 8'' is a roller, 9 is a coarse crusher, 10
11 is a crusher, 12 is a crushed piece, 13 is a screw conveyor, 14 and 15 are scrapers, 16 is a gas inlet, and 17 is a cover. The rotating cylindrical processing apparatus 1 of the present invention generally includes a cylindrical body 4 in which a rotating shaft is supported in the horizontal direction, a cooling or heating mechanism 6 provided inside the cylindrical body 4, and a cooling or heating mechanism 6 provided above the cylindrical body 4. A processing material supply unit 2, a rolling roll 5 for pressing and rolling the processing material 3 supplied onto the cylindrical body, and an endless belt 7 for transferring the processing material 3 while being pressed against the cylindrical body 4. Become.

[0007] Each operation will be explained. A processed material 3 such as a thermoplastic synthetic resin in a molten state, crushed fish or meat, etc., supplied from a processed material supply section 2 is continuously supplied to the surface of a cylindrical body 4 .
A cooling or heating mechanism 6 for cooling or heating the cylindrical body 4 is provided inside the cylindrical body 4. For example, when molten thermoplastic synthetic resin is cooled and solidified, water or an aqueous ethylene glycol solution is used. ,
A liquid or gaseous cooling medium that is normally used as a cooling medium such as an aqueous calcium chloride solution, freon gum, or ammonia gas is supplied into the cylindrical body 4, and processed foods such as fish or minced meat are heated. In the case of processing, an appropriate heating medium such as hot water, steam, dowsome oil, SK oil, mineral oil, silicone oil, molten salt, etc. may be supplied to the inside of the cylindrical body 4.

[0008] The workpiece 3 supplied to the surface of the cylindrical body 4 moves as the cylindrical body 4 rotates, but if the thickness is uneven, there will be uneven cooling or heating, so it is necessary to maintain a constant thickness. be discovered. For this purpose, a rolling roll 5 is used, and the rolling roll 5 is placed on the side in the traveling direction of the processed material 3 from the processed material supply section 2, and has a spring structure, an air cylinder, etc. between it and the cylindrical body 4. It is freely adjustable and adjusts the thickness of the object to be processed to a predetermined thickness. This rolling roll 5 also
Of course, like the cylindrical body 4, a cooling or heating mechanism may be incorporated therein.

[0009] In this way, the object 3 to be treated is pressed and brought into close contact with the surface of the cylindrical body 4 to a predetermined thickness, and is cooled or heated depending on the temperature of the cylindrical body 4. As the cylindrical body 4 rotates, the object 3 to be processed will move to the bottom of the cylindrical body 4, and it is possible that it will be separated from the cylindrical body 4 due to its own weight.
If peeling occurs, defects in cooling or heating processing will occur, so an endless belt 7 is provided from the side to the bottom of the cylindrical body 4 to keep the object 3 in close contact with the cylindrical body 4. For example, the endless belt 7 may have a structure in which it is stretched around rollers 8, 8', and 8'' as shown in the figure.Rollers 8,
By adjusting the positions of 8' and 8'', the pressing position, pressing force, etc. by the endless belt 7 can be adjusted.

[0010] The endless belt 7 is selected from any material such as soft vinyl chloride, synthetic resin such as polyethylene, synthetic rubber, natural rubber, metal, etc., depending on the material of the object 3 to be processed. The object 3 to be processed is transferred while being pressed to the cylindrical body 4 by the endless belt 7 and subjected to cooling or heating treatment, and is then pulverized into raw materials, products, etc.

[0011] As shown in FIG. 1, the thermoplastic synthetic resin (workpiece 3) that has been cooled is peeled off from the cylindrical body 4 and transported along the endless belt 7.
A coarse crusher 9 is provided in front of the endless belt 7, and the workpiece 3 is coarsely crushed. The coarse crusher 9 shown in the figure has a structure in which a large number of pins are embedded around a round rod-shaped core, and rotates to crush the material to be processed, but the structure can be changed as desired depending on the purpose. be.

[0012] The coarse pieces 10 crushed by the coarse crusher 9 are then crushed by a crusher 11 such as a cutter mill to become crushed pieces 12, and the screw conveyor 13
It is transported out and made into a product. Since it is conceivable that the objects to be processed may adhere to the surfaces of the cylindrical body 4 and the rolling roll 5, it is preferable to provide scrapers 14, 15, etc., for example, to scrape them off. In addition, since the device of the present invention is very compact, the entire device is covered with a cover 17, and dehumidified air, dehumidified nitrogen, etc. are introduced into the inside from the gas inlet 16, so that it is isolated from outside air. This makes it possible to solve hygiene problems when used in processing foods, etc.
