Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surimi heating apparatus for heating a surimi formed from fish meat or the like into a predetermined shape such as a tubular shape to produce a kneaded product.

[0002]

2. Description of the Related Art In the case of manufacturing a plate-shaped kneaded product using a raw material such as fish meat as a raw material, the surimi is filled in a concave portion formed in a mold member made of wood or metal.
The surimi is formed into a predetermined shape, taken out of the mold member, and then heated using gas, electricity, steam, or the like as a heating source, thereby preserving the surimi to produce a kneaded product. In the case of manufacturing a cylindrical kneaded product having a through hole in the center, a paste-like surimi is attached to a bar and then heated.

[0003] As described above, after the surimi is formed into a predetermined shape, the surimi is heated to maintain the shape, thereby producing a kneaded product such as a sweet potato or a chikuwa.
In order to finish the kneaded product softer, the molded surimi must be kept at an appropriate temperature for a certain period of time by some means.

[0004] In the case where the surimi adhered to the bar is heated by a heat medium from a heating source such as a gas when producing a cylindrical kneaded product, the surimi is heated from the outside. Since it takes a long time for heat to be transmitted to the surimi, as shown in JP-A-8-38111, the surimi itself is heated by Joule heat generated by the current and heated. Such a heating device has been developed.

[0005]

When a plate-shaped surimi is formed, if it is immediately taken out of a molding machine for forming a product, the product may be deformed or damaged. In order to prevent this, a sitting step or a shape keeping step may be provided. In the sitting or shape keeping process, the body must be kept in a shape retainer such as a retainer for a predetermined time at a predetermined temperature, and the production efficiency cannot be improved.

[0006] In the case where a surimi is heated by Joule heat to produce a soft soft surimi, it is necessary to first form the surimi into a plate shape and then wind the surimi over a rod-shaped electrode through a shape-retaining or sitting process. Required. Next, in order to wind the plate-shaped shaped surimi into a cylindrical shape, an operation of transferring the surimi to the winding machine is required.

[0007] However, if such a delivery operation is performed, a surimi formed in a plate shape may be deformed or broken at the time of the delivery, and the work efficiency is significantly reduced.

An object of the present invention is to make it possible to efficiently manufacture a kneaded product using a surimi as a raw material in a predetermined shape with good yield.

The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

The right-hand feed roller 12b is driven to rotate, and the rotation center axis Ob is parallel to the rotation center axis Oa.
Is driven to rotate counterclockwise around the center.

Below the feed rollers 12a and 12b, there is arranged a first rotating body 14 for forming the surimi 10a into a plate shape. The first rotating body 14 has a center on a rotation center axis Oc parallel to the rotation center axes Oa and Ob. Then, the first rotating body 14 rotates. The rotating body 14 is a paste-like surimi 10a
This is a molding machine for molding into a plate shape.

As shown in FIG. 3, a substantially quadrangular plate-shaped recess 15 is formed on the outer peripheral surface of the first rotating body 14, and this recess 15 is formed as shown in FIG. A total of eight are provided with a phase shift of 45 degrees with respect to the rotation center Oc. Can be.

Therefore, the paste-like surimi 10a in the hopper 11 is rotated by rotating the pair of feed rollers 12a and 12b while rotating the first rotating body 14 in the counterclockwise direction as indicated by the arrow in FIG. By filling the inside of the concave portion 15, the surimi 10b can be formed in a plate shape corresponding to the shape of the concave portion 15. In the case shown in the figure, the concave portion 15 that has become the upper position with the rotation of the first rotating body 14 is the filling position where the surimi 10a is filled, and the lower position is the discharging position.
