Abstract

PURPOSE: To facilitate repair and cleaning of cutting edges by fixedly fitting the disklike cutting edge and a disklike spacer in superposition round each of the first and second rotary shafts arranged parallel to each other for the formation of desired rotary cutting members. CONSTITUTION: A disklike cutting edge 20 and a disklike spacer 22 are fixedly fitted in superposition round each of first and second rotary shafts 16 and 18 arranged parallel to each other to form a pair of rotary cutting members. After the interval between the first and second rotary shafts 16 and 18 is adjusted fine by means of an adjusting screw 46, these rotary shafts 16 and 18 are rotated in the opposite directions to cause the coaction of the cutting edges 20 on these shafts to chop fine a sheetlike food material passed through between the cutting edges 20 or cut the material parallel partially. If either cutting edge 20 is broken, it is removed from the associated rotary shaft 16 or 18 and is replaced by a new one. If either cutting edge 20 is clogged with the material, it is also removed from the associated rotary shaft 16 or 18 for cleaning to avoid such a material clog.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to an apparatus for cutting thin sheets of food material such as minced fish into thin pieces, or for making mutually parallel cuts in the same sheet. .

Technical Background In recent years, in the field of minced fish products, products have been developed in which minced fish is made into sheets, cut into thin strips, or made with mutually parallel cuts, and then put together into sticks to resemble crab leg meat. is widely sold.

In order to cut the sheet-shaped surimi as described above or cut it into thin strips, a device as shown in FIG. 4 is used.

That is, this device has a pair of rotary cutting members C set parallel to each other, and each cutting member has large diameter cutting blade portions and small diameter groove portions arranged alternately in the axial direction. S, and are mutually set so that one cutting blade portion slightly enters or is close to the groove portion of the other. With this device, in order to cut the sheet-like surimi into long strips, the re-rotating cutting members are rotated in opposite directions, the sheet-like surimi is passed between them, and the surimi is cut into strips by the re-rotating cutting member. By cutting between adjacent edge portions, a strip of approximately the width of the groove is formed.

The above-mentioned rotary cutting member was made by cutting the above-mentioned groove portion from a single cylindrical metal. Therefore, such conventional rotary cutting members have the following problems.

In other words, in conventional cutting blades, the cutting blade portion and the groove portion are integrally formed as described above, so if a part of the cutting blade is damaged or the rotary cutting member becomes dull, However, it is necessary to replace the entire rotary cutting member, and it is very difficult to repair it, so it has generally been done by a specialist.

Furthermore, since the rotary cutting member is manufactured as described above, if the width of the cutting blade portion and the groove portion becomes smaller than a certain level, it becomes extremely difficult to manufacture it, and in fact, if the width becomes less than 1 mm. However, its production was impossible.

Furthermore, when the widths of the cutting blade portion and the groove portion become smaller, there is a problem that it becomes difficult to clean the cutting member.

OBJECTS OF THE INVENTION In view of the above points, an object of the present invention is to provide a sheet-like food material shredding device equipped with a rotary cutting member that is easy to manufacture and maintain.

In other words, the device according to the present invention has first and second rotating shafts that are set parallel to each other, and are fitted concentrically on the rotating shafts and overlapped, and rotate together with the rotating shafts. and a spacer set between the disk-shaped cutting blades adjacent to each other on the rotation axis, the first and second disk-shaped cutting blades are positioned relative to each other so as to slit or make mutually parallel cuts in the sheet food material passed between them by their interaction.

Functions and Effects of the Invention The sheet-like food material shredding device according to the present invention has the above-mentioned configuration. Therefore, when manufacturing this, the disc-shaped cutting blade and the spacer are separated from the rotating shaft. These were manufactured in advance, and then fitted and stacked one after another on the rotating shaft.
By fixing it, a device corresponding to the rotary cutting member in the conventional device described above can be manufactured, and when cutting a sheet-shaped food material, it can be performed in the same manner as in the conventional device.

If the disc-shaped cutting blade is damaged, only the damaged one needs to be replaced with a new one. In addition, when the cutting blade loses its sharpness, all you have to do is replace the entire cutting blade with a new one from the rotating shaft, and the removed disc-shaped cutting blade can be polished separately from the rotating shaft. I can do it.

Furthermore, if material gets stuck between the disc-shaped cutting blades during shredding work of sheet-shaped food materials, the cutting blades can be easily cleaned by removing them from the rotating shaft.

As can be seen from the above, in the apparatus according to the present invention, the production and maintenance of the cutting member are much easier than in the conventional apparatus.

In addition, since the disc-shaped cutting blade and spacer can be manufactured separately from the rotating shaft, they can be made extremely thin, with a thickness of less than lam, especially 0.3+u+ to 0.1 mm.
It has become possible to manufacture products of a certain thickness, and therefore it has become possible to cut out strips of widths that were not possible with conventional equipment, and to make cuts of corresponding widths.
