Description

[Detailed description of the invention] [Industrial application field] This invention relates to a cutter for opening and flattening the bellies of medium-sized shrimp as an ingredient for sushi neta and fried foods.

[Conventional technology]

The shrimp used for sushi neta and fries have a body length of 5.
The heads of ~15cm pieces are removed and boiled, the ventral sides are opened and flattened, and the shells are simultaneously peeled off and removed, but this is mostly done by hand.

[Problem that the invention attempts to solve]

The above-mentioned process of opening medium-sized shrimp is not only inefficient and costly, but also requires skill because the resulting product may be defective due to deformation.

[Means for solving problems]

In order to solve the above problems, this invention arranges a feeding belt on a base plate, and arranges a round blade and a small roller group on the feeding belt in that order in the feeding direction, and the small roller group has an abacus-shaped shape. The abacus-shaped and cylindrical ones are arranged in that order, and the ridge lines of the abacus-shaped ones are arranged in order from acute to obtuse, and feeding belts are arranged on both sides of the round blade in parallel with and facing the round blade. A push spring pin for the round blade is disposed on the back surface of the opposing feed belts in a portion corresponding to the round blade, and the small roller group is a shrimp cutter driven in the feeding direction.

[Effect]

Drives each feed belt, rotates the round blade at high speed,
The small roller group is driven at a rotation speed that matches the running speed of the feed belt, and a shrimp (headless shrimp that has been straightened and boiled) is placed on the feed belt on the base plate on the feed side of the left and right opposing feed belts. medium-sized shrimp)
By feeding the shrimp with the ventral side facing upward, the shrimp is sandwiched between the left and right belts, reaches a round blade, and is incised over the entire length of the ventral side.Then, as it passes under the group of small rollers, it is cut by the first roller. The incisions are opened at an acute angle, then opened at an obtuse angle by the next roller, and completely opened by the last roller, and pressed slightly, making it easier to separate the shell from the meat.

〔Example〕

FIG. 1 is a front view of an example of a shrimp cutter according to the present invention, and FIG. 2 is a plan view, where 1 is a base plate (top plate) of the cutter.

A feed belt 2 (the upper running band of the belt) is arranged on the base plate 1, and on this feed belt, a group of rollers consisting of a round blade 3 and small rollers 4a, 4b, and 4c are arranged in the belt feeding direction. They are arranged in that order.
In addition, the small rollers 4a and 4b have an abacus bead shape, and the roller 4c has a cylindrical shape.
Although the ridge line of is at an acute angle, the small roller 4b is at an obtuse angle.

On both sides of the round blade 3, feeding belts 5a and 5b facing the round blade in parallel are arranged with a required interval, and the back surfaces of the feeding belts 5a and 5b correspond to the round blade 3. A push spring pin 6 to the round blade is arranged in the part.

The push spring pin 6 is supported by a bearing 7 so that it can move forward and backward with its head facing the belt, and a spring 8 is installed in a compressed state between the head of the pin and the bearing, and a nut 9 is screwed into the pin. This adjusts the degree of pressure contact of the head of the pin with the feed belts 5a, 5b, and the pin easily retreats when pressure is applied from the belt side. 10 is a receiving plate interposed between the feed belts 5a, 5b and the belt push spring pin 6.

The small rollers 4a, 4b, 4c are driven to rotate in the running direction in accordance with the running speed of the feed belt 2.

In the figure, 11 is the tension roller of the feed belt 2, 12 is the adjustment lever of the tension roller 11, 13 is the tension roller of the feed belts 5a, 5b, 14 is its spring, 15
a, 15b, 15c are small rollers 4a, 4b, 4
The position adjustment bolt c is shown.

The round blade 3, small rollers 4a, 4b, 4c, feed belts 2, 5a, 5b, etc. are driven by a drive source such as a geared motor, but are not shown.

In order to open and process shrimp with this cutter, place the shrimp 16 on the running feed belt with its ventral side facing upwards, and feed it to the feeding sides of the left and right opposing feed belts 5a and 5b. The shrimp is made a cut on the ventral side by the round blade 3 and sent to the small roller group, and the acute ridge of the first abacus-shaped roller 4a of the small roller group enters the cut line of the shrimp and slightly cuts the abdomen. Open the shrimp, then open it wide with the second roller 4b, flatten it and lightly press it with the third roller 4c until it becomes flat.
As soon as it reaches 6a, the shell becomes easier to peel off.

〔effect〕

The shrimp cutter of this invention is made by placing boiled, headless medium-sized shrimp on a belt running on a base with the ventral side facing up and feeding it between the left and right feeding belts, which are facing each other. A notch is made on the belly with a round blade, and then as the shrimp passes under a group of small rollers, the notch is opened step by step, and finally it is completely opened and lightly pressed to become a flat shrimp. This makes it easier to peel off the shell, and all of this is done automatically, which has the effect of lowering costs.

Moreover, this cutter has the effect that the resulting product hardly loses its shape or is defective.

Claims (1)

[Scope of utility model registration request] A feeding belt is arranged on the base plate, and a round blade and a small roller group are arranged on the feeding belt in that order in the feeding direction, and the small roller group is an abacus ball-shaped one and a cylindrical one in that order. The rims of the spherical blades are arranged in order from acute to obtuse, and on both sides of the round blade, feeding belts are arranged parallel to the round blade and facing each other at intervals. A shrimp cutter characterized in that a belt pressing spring pin for the round blade is disposed on the back side in a portion corresponding to the round blade, and the small roller group is driven in the feeding direction.
