DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for heat treating materials, and more specifically, to
The present invention relates to an apparatus for heat treating cylindrical food products.

The apparatus of the present invention is most convenient for heat treating sausage materials to give good taste quality and good appearance.

This device can also be used in the woodworking and construction industry for drying the surfaces of materials.

A known apparatus for heat treating cylindrical products is disclosed in US Pat. No. 3,517,606.

This device is a device designed for processing sausage materials.

The known apparatus for heat treating sausage ingredients consists of a frame made of a set of parallel, spaced wire members.

The wire member defines a shape that includes a plurality of regularly alternating ridges and depressions that prevent the materials from coming into contact with each other.

This equipment cannot simultaneously heat-treat the material and transport the material.

Therefore, the treatment medium cannot act uniformly on the material and therefore a material of appropriate quality cannot be guaranteed.

Another drawback is the difficulty in carrying out sanitation of the equipment.

The detergent-free action is hindered by a plurality of alternating ridges and depressions in which oily particles are deposited.

The most similar technical means and results are, for example, Soviet Union Inventor Certificate No. 257309, (Ot, A23 B12O3, 19
68) is an apparatus for heat treatment of cylindrical materials.

This device is also designed for processing sausage material and consists of a processing section with a source of thermal radiation and a transport mechanism.

Within the compartment are vertically disposed horizontal plates, the plates are spaced apart and have corrugated surfaces, and the transport mechanism is disposed on the plates. Each plate has rack teeth driven along a closed path and has parallel straps secured thereto.

The action of the strap acts like a pusher on the product, flipping the material to ensure its handling as it moves forward within the compartment.

The disadvantages of this device include that the strap comes into contact with the material, which deforms it, and that the strap results in uneven rotation for the purpose of turning the material at the correct spacing. Become.

From the viewpoint of equipment hygiene, the leather straps are placed at certain intervals and fixed at an angle to the rack teeth, allowing rapid cleaning of all surfaces of the equipment and cleaning of the entire equipment. There is a difficulty in that it cannot be washed.

Furthermore, it cannot process various cylindrical materials.

The need to process various types of large or small diameter cylindrical materials requires substantial structural modification of the transport mechanism.

The object of the invention is to obtain a device that does not have the disadvantages mentioned above.

The device for heat treatment of cylindrical materials of the present invention ensures uniform heat treatment for the whole device, does not deform the material during processing, and the sanitary treatment of the device after removing the material is easy, and various It is equipped with a conveying mechanism designed to handle cylindrical materials with a diameter of .

The device consists of a compartment with a thermal radiation source and a transport mechanism.

In the present invention, the conveying mechanism includes a support belt and a pair of upper chain conveyors extending along the edges of the support belt of the material loading conveyor device within the compartment.
Each chain conveyor has a lower chain conveyor truck, and each chain conveyor has spaced apart discs arranged to engage the edges of the belt on each side of the belt.

This structure allows uniform heat treatment of cylindrical food products passing within the heat treatment zone.

This is due to the fact that the belt assumes a moving corrugation under the action of a pair of upper chain conveyors and a pair of lower chain conveyors.

The moving waveform is produced by the discs of the chain conveyor extending on each side of the belt, the axes of the discs belonging to the lower conveyor being kept spaced apart from the axis of the discs belonging to the upper conveyor, thus It serves to form moving ridges and depressions on the belt in a moving wave shape while the conveyor moves relative to the belt.

During heat treatment of the material in the compartment with the infrared radiation source, the material supported in the recess of the support belt is rotated uniformly and undergoes a forward movement.

It is based on the movement of a material loading conveyor and the movement of two pairs of chain conveyors, thus ensuring uniform treatment of the material surface.

By adjusting the speed of both the rotation and forward movement of the material over a wide range, the desired conditions can be obtained, selected to most ideally heat treat each type and diameter of cylindrical material. .

It is expedient to provide a lower pair of chain conveyors, with another disc always in contact with the supporting belt from below the lower chain conveyor.
