Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a heating device for a paste product, which heats a paste product made of fish meat or the like by applying electric current to the paste product, and in particular, The present invention relates to a heating device that continuously heats while transporting.

(Prior art) Paste products such as kamaboko, chikuwa, and fish sausage are usually made by grinding fish meat with seasonings and forming a paste into a shape suitable for each product, and then the product, that is, the food, is shaped and sterilized. It's heated to do it. For this heating, a steaming method is often used, in which the product is heated by steam. Since this method requires time to heat, in order to achieve the desired heating in a short period of time, there is a method in which electricity is applied to the kneaded product and it is heated using Joule heat, as shown in Japanese Patent Publication No. 55-48789, for example. It is being adopted.

(Problems to be Solved by the Invention) In this type of heating device, electricity is applied to the conductive product using electrodes while the paste product is held between the electrodes, and the electrodes and the product are connected with each other. In order to avoid direct contact with the electrode, the product is covered with a water-permeable bag or the like, or a water-permeable membrane is interposed between the electrode and the product.

However, in this method, once heating for one batch is completed, it is necessary to discharge the product and heat the next product, so it is a so-called batch method, and the kneaded product cannot be heated continuously.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to make it possible to continuously heat a dough product by utilizing Joule heat.

(Means for Solving the Problems) The present invention for achieving the above object forms a substantially quadrilateral discharge port in a dough product extruder, and a cross section extruded from the discharge port in front of the dough product extruder is approximately A first transporting electrode is disposed corresponding to one side of the quadrilateral dough product, and a second transporting electrode is arranged to work together with the first transporting electrode to heat the dough product while transporting it.
A transport electrode is arranged opposite to the first transport electrode, and a first transport electrode moves in synchronization with the first transport electrode.
A water-permeable film is provided on the transport surface of the first transport electrode, and a second water-permeable film that moves in synchronization with the second transport electrode is provided on the transport surface of the second transport electrode, and the first and a second water-permeable film, which is provided with a water supply means for supplying water to the water-permeable film before reaching each of the electrodes.

Furthermore, the present invention provides a first transport electrode and a second transport electrode, each having a transport surface that contacts one side of a dough product formed into a predetermined shape, so as to mutually define a predetermined space for transporting a dough product. A first water-permeable film is provided on the transport surface of the first transport electrode, and a first water-permeable film that is arranged adjacent to the film and moves in synchronization with the first transport electrode is provided on the transport surface of the first transport electrode. 2. A water-permeable film is provided on the transport surface of the second transport electrode, and a water supply means is provided on the water-permeable film for supplying water to the first and second water-permeable films before reaching each of the electrodes. This is a continuous heating device for kneaded products.

(Function) The dough product material extruded from the dough product extruder with a quadrilateral cross section has its two opposing sides contacting the transport surface of the transport electrode via the water permeable film, and Continuously transported by electrodes. During this transport process, the dough product material is heated by the voltage supplied to both transport electrodes. Since the transport electrode and the dough product material do not come into direct contact with each other due to the water-permeable film, adhesion of the paste product to the transport electrode is prevented, and the surface of the paste product is well finished. In this way, the heated dough product extruded from the dough extruder into a continuous band shape is cut and separated into predetermined lengths and packaged.

On the other hand, in the case where the dough products are formed into a predetermined shape before being heated, each dough product is separated and continuously placed between the respective transport surfaces of two transport electrodes. It is heated while being conveyed continuously. In this case as well, since the transport electrode and the dough product material do not come into direct contact with each other due to the water-permeable film, adhesion of the paste product to the transport electrode is prevented, and
The surface of the paste product is well finished.
