Is arranged in the container together with the crusher (11) and has a function of carrying out the crushed pieces (12). The crushed pieces (12) are
The product is carried out in one direction perpendicular to the paper surface.

Since it is possible that the object to be treated adheres to the surfaces of the cylindrical body (4) and the rolling roll (5), for example, scrapers (14) and (15) are provided and adhered. It is preferable to scrape off the object to be treated. Since the device of the present invention has a compact structure, it is possible to cover the entire device with, for example, a simple cover (17), whereby the object to be processed (3) and the outside air can be easily shut off. You can As a result, it is possible to solve hygiene problems when used for processing foods and the like. The gas lead-out port (16) is provided as necessary for leading out dehumidified air, dehumidified nitrogen, etc., and is provided at an arbitrary place inside the cover (17).

In the apparatus of the present invention, it is important that the above-mentioned endless belt (7) is composed of a porous belt having a large number of ventilation holes. The material of the porous belt is easy to bend, and as long as it can exert the function of adhering the object (3) to the tubular body (4), synthetic resin such as soft vinyl chloride, polyethylene, synthetic rubber, natural rubber, etc. It can be selected from arbitrary materials such as rubber and metal according to the material of the object to be processed (3).

The porous belt may be, for example, a flat belt in which a large number of air holes are formed or a porous belt in which a wire material is knitted. An example of the former is a porous belt composed of a punching metal sheet, and an example of the latter is a mesh belt such as a wire mesh belt.

In the case of a porous belt composed of punching metal sheets, it is necessary that the thickness of the sheet be such that flexibility as an endless belt is exhibited. The wire diameter of the wire mesh belt is usually 0.5 to 3 mm.
Is the range. In the present invention, the opening ratio of the ventilation holes per unit area means the unit area (for example, 1 m ² ).
It means the ratio of the opening area of all the vent holes existing per hit.

In the present invention, at least the surface of the porous belt which is in contact with the article to be treated (3) is preferably coated with a resin having releasability for the article to be treated (3). Usually, fluorine resin (for example, the product "Teflon")
And silicone resins are the most processed materials (3)
It has releasability against. The release resin can be coated on the entire surface in consideration of the convenience of coating process. For example, in the case of a wire mesh belt,
By braiding the wire material dipped in the mold release resin solution,
It is possible to obtain a wire mesh belt coated with a release resin on the entire surface.

Further, in the present invention, a cooling or heating mechanism (18) for cooling or heating the object (3) to be processed through the endless belt (7) located on the outer periphery of the cylindrical body (4) is provided. preferable. The cooling or heating mechanism (18) is usually composed of an outlet for the cooled or heated gas. However, for example, a rod-shaped heater can be adopted as the heating mechanism (18). When the cooling or heating mechanism (18) is constituted by the cooled or heated gas outlet, the object to be treated (3) is cooled and solidified from the gas outlet. The cooled gas is discharged, and in the case where the object (3) to be processed is heat-treated, the heated gas is discharged.

When the apparatus of the present invention is used for cooling the object to be processed (3), since the endless belt (7) is composed of a porous belt, the cylindrical body of the object to be processed (3) ( The surface not in contact with 4) is also efficiently radiated and cooled well. If the porous endless belt (7) is combined with the cooling or heating mechanism (18), the object (3) having a small thermal conductivity can be cooled or heat-treated, or the object (3) can be cooled. Even when the processing amount increases and the thickness of the object (3) to be pressed against the cylindrical body (4) and rolled increases, the processing can be performed extremely efficiently.

A rod-shaped heater may be used as the heating mechanism (20). When the cooling or heating mechanism (20) is composed of the cooled or heated gas outlet, the cooled gas is discharged from the gas outlet when the object (3) is cooled. Further, when the object to be processed (3) is heat-treated, the heated gas is discharged.

The cooling or heating mechanism (20) enhances the efficiency of the cooling or heating treatment of the object (3) to be treated. And
When the apparatus of the present invention is used for cooling the object to be processed (3), the cooled gas discharged from the cooling mechanism (20) (for example, the gas outlet) cools the object to be processed (3). The solidification is promoted, the object to be treated (3) is prevented from being bitten into the air holes of the porous endless belt (7), and the object to be treated (3) is more favorably peeled from the endless belt (7). .

The cooled or heated gas can be easily obtained by using a cooling device or a heating device, and the cooled gas can also be obtained by adiabatic expansion of compressed gas. The temperature of each gas is appropriately determined according to the purpose.

In the apparatus of the present invention, the object to be processed (3) is processed as follows. That is, first, the cylindrical body (4)
The object to be treated (3) supplied to the surface of is moved according to the rotation of the cylindrical body (4) and is made to have a constant thickness by the rolling roll (5). As a result, uneven cooling or heating that occurs when the thickness of the object to be processed (3) is not uniform is prevented.

Next, the object to be treated (3) pressed and brought into close contact with the surface of the cylindrical body (4) with a predetermined thickness is cooled or heated according to the temperature of the cylindrical body (4). Then, the object to be processed (3) moves to the lower side of the tubular body (4) as the tubular body (4) rotates. The endless belt (7) prevents the object to be treated (3) from peeling off from the tubular body (4) due to its own weight. As a result, the occurrence of defective cooling or heat treatment caused by peeling of the object to be processed (3) is prevented.

Since the endless belt (7) is made of a porous belt, the surface of the object (3) to be processed which is not in contact with the cylindrical body (4) is also efficiently radiated and cooled well. . Moreover, in a preferred embodiment, when the cooling or heating mechanism (18) is provided, the object to be processed (3) having a low thermal conductivity is cooled or heat-treated, or the amount of the object to be processed (3) is increased. Even when the thickness of the object to be processed (3) pressed against the cylindrical body (4) and rolled increases, the processing can be performed extremely efficiently.

Next, the object to be treated (3) which has been transferred while being pressed against the tubular body (4) by the endless belt (7) and subjected to cooling or heat treatment is peeled from the tubular body (4). Then, it is transferred along the endless belt (7) and roughly crushed by the crusher (9). The crushed pieces (10) crushed by the crusher (9) are crushed by the crusher (11) into crushed pieces (12). And crushed pieces (12)
Is carried out by a screw conveyor (13) to be a product.

The apparatus of the present invention can be suitably used, for example, when a molten thermoplastic synthetic resin is cooled and solidified, or when a processed food such as fish or meat surimi is heat-treated. Can be done.
