Description

[Detailed description of the invention] This invention relates to dried bonito flakes.

Conventionally, a planer blade is attached to the side surface of a rotating body such as a cylinder or a disc, and the raw material knots are cut by rotating the rotary cutting body while pressing the raw material knots to be cut against this side surface, or by cutting the raw material knots on the outer periphery. A rotary blade with a double-striped cutting edge was used to press the raw material to be cut against the rotary blade and cut it, thereby creating kerifobushi.

However, in conventional cutting methods such as the former, the entire cutting surface of the raw material joint is constantly in contact with the side surface of the rotary cutting body during the cutting operation, so frictional heat is generated between the raw material joint and the side surface of the rotary cutting body. As a result, the cut surface of the raw material joints becomes excessively dry, which not only makes it easy for the cut joints to be finely pulverized, but also has the drawback of loss of aroma and deterioration of quality due to oxidation.

Furthermore, in the latter method, even if one or a portion of the cutting blades provided on the outer periphery are damaged, the entire rotary blade must be replaced, and therefore the maintenance cost of the device itself is high.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide bonito flakes that are free from the disadvantages of powdering, loss of aroma, and deterioration of quality due to oxidation caused by friction heat during rotation as described above. Another object of the present invention is to provide a kerifobushi that does not have the above-mentioned drawbacks and can be cut into strips of a desired size without using any special additional means.

Therefore, the cutting knot according to the present invention is preferably provided with a D-circular groove on the side surface of a rotary cutting machine to which a plurality of cutting blades are attached, and a narrow flat portion in which the raw material knot to be cut extends along each groove. The machine is manufactured using equipment configured to make sliding contact only with It becomes thin and has an irregular shape that is not flat.

Further, a cutting joint according to another object of the present invention is preferably provided with concentric grooves at a constant pitch on the side surface of a rotary cutting machine, and a plurality of cutting grooves each having a constant pitch on the side surface. The blades are mounted, and each notch of each cutting blade is manufactured in a machine such that it is located on the narrow flat area between the grooves of the rotary cutting machine, and the cutter is made with a size corresponding to the desired size, i.e., the spacing between the cuts of the cutting blade. It is formed into a strip, and has a relatively thick center portion corresponding to the groove, and thin, irregularly shaped portions on both sides.

As described above, in the cutting joint according to the present invention, the contact between the rotary cutting machine and the raw material joint is carried out on a narrow flat part along the groove, so the frictional heat generated during rotary cutting is far greater than that of the conventional full-surface contact type. As a result, there is less pulverization of bonito flakes caused by excessive drying due to frictional heat, less loss of aroma, and less quality deterioration due to oxidation. In addition, the kerifushi according to the present invention, which is manufactured using a cutting blade with notches at regular intervals, has both sides rubbed by the narrow flat part between the grooves of the rotary cutting machine during cutting, so the central part Because the temperature is higher than the part that has passed over the groove and is pressed harder, the thickness on both sides becomes thinner and wrinkled, resulting in an irregular shape instead of a straight line. It has good bulk, makes soup stock easily, and has a good texture.

Hereinafter, the production of bonito flakes according to the present invention will be further explained with reference to the accompanying drawings.

1 and 2 schematically show the main parts of the apparatus according to the first embodiment of the apparatus for producing dried bonito flakes according to the present invention.
1 shows a drive shaft driven by a suitable drive motor (not shown), this drive shaft 1 is bearing in a frame (not shown) of the apparatus, and a rotary cutting machine 2 is mounted thereon.

As shown in FIG. 2, the rotary cutting machine 2 has a plurality (for example, about 14) of planer blade attachment openings 3 provided at equal intervals at positions equidistant from the central axis of the drive shaft 1. Only two of them are shown in FIG. A planer blade 4 is removably and adjustable attached to each planer blade attachment opening 3, and each planer blade 4 naturally projects slightly from one side surface 2a of the rotary cutting machine 2 in the direction of rotation thereof. In addition, one or more circular grooves 5 are formed between each adjacent planer blade mounting opening □ 3 on the - side 2 a of the rotary cutting machine 2, and a narrow flat part is formed between each groove 5. 6 (same level as one side 2a). In this case, the number and dimensions of the grooves 5 as well as the dimensions and number of the planer blades 4 (and thus the spacing between adjacent planer blades 4) can be selected appropriately. In FIG. 1, 7 is a pressure supply hopper for the raw material joint 8, and this press supply hopper 7 is used to press the raw material joint 8 to be cut against one side 2a of the rotary cutting machine 2.
It has an inclined guide surface 9 that guides the material at a constant angle of inclination, and a pressing member 10 that presses the raw material node 8 with a constant pressure. ) is always forced towards the rotary cutting machine 2 by suitable means such as.

The operation of the apparatus of the present invention configured as described above will be briefly described. The rotary cutting machine 2 is rotated by the drive motor at a desired rotational speed in the direction of arrow A, and the material strip 8 to be cut is pressed against one side 2a of the rotary cutting machine 2 at a certain inclination angle. Suppose that it is supplied.

In this state, the cutting machine surface of the raw material knot 8 is sequentially cut by each planer blade 4 while contacting the narrow flat part 6 between the grooves 5, and the cut knot thus cut is attached to the cutting edge and the planer blade mounting closure. 3 to the other side or inside of the rotary cutting machine 2, and is collected in a collection hopper (not shown) and can be sent to a subsequent processing device. The device according to this embodiment can be advantageously used to shave raw material knots into relatively large sizes, and can therefore be used particularly for producing bonito flakes and the like.

FIG.
1 and 2, the apparatus itself may be constructed exactly as shown in FIGS.
3 are provided, each incision 13 being configured to lie on a narrow flat 6 between adjacent grooves 5.

Therefore, since the device according to this modified embodiment cuts the material knots at intervals of the cuts 13 of the planer blade 12, it is possible to directly obtain shaved knots that are relatively finely fragmented. In this embodiment as well, the dimensions of the planer blade 12, the intervals between the notches 13 thereof, the dimensions of the grooves 5, etc. can of course be designed arbitrarily.
