Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to an automatic rice cake milling machine used in the food processing industry such as confectionery and rice cakes.

(Prior art) An automatic rice cake milling machine is composed of a mortar and a punch, and the rice cake in the mortar is punched by moving the punch up and down to produce a rice cake. Unless the location where the punch is made is changed at the time of punching, a more uniform product cannot be produced. Conventional means are disclosed in JP-B-49-27349, JP-A-56-21565, and JP-B-56 As shown in No. -21255, a rotating body is provided in the mortar, and the position of the rice cake is changed by automatically turning the rice cake.

A mochi-milling machine equipped with this automatic barring mechanism has been proposed in which an opening for discharging the mochi is provided on the front side of the peripheral wall of the mortar body (Japanese Utility Model Laid-Open No. 63-132591, 63-63). 136532).

(Problems to be Solved by the Invention) By the way, the above-mentioned automatic mochi-milling machine automatically performs the returning operation by moving the position of the rice cake mass put into the mortar by rotating the rotating body. However, if the degree of adhesion of the rice cake to the inner surface of the peripheral wall of the mortar is not appropriate due to the adhesive force of the rice cake, the rice cake will not be in a lump state. That is, if the adhesion between the rice cake A and the mortar is appropriate as shown in FIG. 5, the rice cake A moves in a lump state and twists and rolls in the mortar 01. But the mortar body 01 made of metal
When the rice cake is heated by the heat of the rice cake, the adhesive force between the rice cake A and the mortar body 01 is increased, and the rice cake A is pulled into an elongated state by the rotating body 02. (Fig. 5 b). Of course, if the temperature of the mortar body 01 is low, it will only follow the rotation of the rotational force and will not be in a twisted state, and no turning operation will be performed.

Therefore, in a conventional automatic rice cake mill with an opening and closing device for removing and opening a rice cake, the temperature of the mortar is not adjusted because the opening having the opening lid is simply provided. Therefore, the mortar 01 is immediately heated by the heat of the rice cake, the adhesive force with the rice cake is increased, and the rice cake A is in an elongated state. When the opening 03 is opened, it is taken out and transported in a slender state to an unloading section 04 (usually using a transport conveyor) 04 adjacent to the opening 03 (FIG. 6A). As described above, the rice cake A is discharged from the opening in a stretched state, not in a lump state, and transported after the discharge,
It is not possible to efficiently perform processing such as work molding.

Also, even if you try to maintain the optimal state by performing temperature control of the mortar, the mortar is affected by the outside temperature at the beginning of grinding,
After several rounds of mochi milling, the temperature rises due to the heat of the mochi (the steamed rice temperature is around 90 ° C), so maintaining the optimal state by controlling the temperature of the mortar is a complicated task. Becomes

(Means for Solving the Problems) In view of the above-mentioned stand, the present invention proposes an automatic rice cake milling machine in which a mortar having an opening is improved.

In the automatic rice cake milling machine according to the present invention, a rotary body is inserted into the center of a mortar provided with a bowl-shaped peripheral wall, and a punch body which moves up and down with respect to the mortar is provided above the rotary body, and on the front side of the mortar. In a machine, an opening for discharging rice cake having a shape obtained by cutting a peripheral wall is formed, and an opening / closing mechanism is attached to the opening, and an opening / closing door having an inner surface matching the inner surface shape of the peripheral wall of the mortar is mounted. On the outer periphery of the peripheral wall excluding the opening of the cast iron mortar, an outer peripheral wall is provided to form a double wall and the peripheral wall of the opening forming portion is made thicker by matching the outer wall at the lower side, and the inner peripheral wall at the upper side. The upper part is gradually thinned to have a corresponding thickness, and a rice cake receiving part is formed on the end face of the opening.

(Action) Hot or cold water is poured into the gap between the inner and outer peripheral walls of the mortar, and the temperature of the mortar is adjusted to adjust the adhesive force between the mortar and the rice cake. When the opening is opened, the rice cake is automatically discharged from the opening by the centrifugal force of the rice cake mass rotated by the rotating body. In particular, as shown in FIG. 6B, even if the temperature of the mortar is not in an optimal state for discharging and the rice cake A is in a slender state, if the opening is opened as it is, rice cake A will be below the opening end face. It collides with the part of the rice cake receiving part, sequentially forms a lump, becomes a certain size, naturally moves out of the mortar (conveying conveyor 04) and is discharged.

(Example) Next, the Example of this invention is described based on drawing.

The automatic rice cake mill comprises a mortar mechanism and a punch mechanism. The mortar mechanism comprises a base 1, a mortar 2, and a lid opening / closing section 3. The base 1 is provided with a rotating base 12 inside a cylindrical mort base 11, and an upper surface of the rotating base 12. And a rotating body 14 connected to the rotating shaft 13.

The mortar 2 has a main body 21 made of cast iron and having a bowl-shaped peripheral wall,
A through hole in the center bottom of the main body 21 that matches the outer diameter of the rotating body 14
22 and the front peripheral wall is provided with an opening 23 of a suitable size obtained by cutting the peripheral wall, and an outer wall is provided on the outer periphery of the peripheral wall of the main body 21 other than the opening 23 to form a double wall surface. A gap 24 is formed between the inner and outer peripheral walls. The peripheral wall portion where the opening 23 is formed is made thicker by making the lower portion correspond to the outer wall, and gradually thinner at the upper portion so that the upper portion has a thickness corresponding to the inner peripheral wall. The part is a mochi receiving part. That is, the lower part of the inner end of the opening 23 is wider than the upper edge of the peripheral wall.

The lid opening / closing section 3 includes an opening / closing lid 31 having an inner surface that matches the inner surface of the peripheral wall of the mortar 2 when the opening 23 is closed, and an opening / closing mechanism that opens and closes the opening / closing lid 31. The opening 32 is provided with a hinge 32 that can be freely opened and closed, and an operating unit 33 that opens and closes the opening and closing lid 31.

The punch mechanism uses a crank (not shown), etc.
It is provided with a punch body 4 that moves up and down above 14.

In order to make rice cakes using the automatic rice cake milling machine, first, warm water is poured into the cavity 24 to warm the mortar body 21 to about 40 ° C., and then the rice cake (steamed rice block) ) Is put into the mortar body 21, and the punch body 4 is moved up and down to punch the rice cake inside,
At the same time, the rotating body 14 changes the position of the rice cake (steamed rice chunk) and the punching point is changed to produce a uniform punched rice cake. When the punching is completed, the rotating body 14 is rotated and the opening is opened. When opening the opening 23 by operating the lid 31 that closed the 23,
The polished rice cake rolls on the inner wall of the peripheral wall of the mortar 21 and reaches the opening 23. Even if the rice cake is not in a beautiful lump state, it successively collides with the inner end surface (mochi receiving portion) of the opening 23, and The rice cake is formed into one lump at the end face, and is discharged out of the die.

When one pestle milling operation is completed, the next steamed rice is sequentially poured into the mortar body 21
And then milling again, but the temperature of the steamed rice is high (about 90 ° C), so the temperature of
Since the adhesion between the rice cake 21 and the rice cake becomes strong and it becomes difficult to return the rice cake and discharge the rice cake by rotation of the rotating body 14, cold water is poured into the void 24 to adjust the temperature of the mill body 21.

Note that the present invention is not limited to the above-described and illustrated embodiments, and the present invention is not limited to the specific structure such as a punch mechanism and a rotating mechanism of a rotating body as long as the mortar body has an opening and a double wall surface. Can be arbitrarily determined.

(Effects of the Invention) As described above, the present invention provides an opening with a lid on the front surface of the peripheral wall of the mortar and has a double wall surface other than the opening, thereby enabling temperature control of the mortar and the peripheral wall of the opening. The thickness of the inner part of the lower part of the opening is made wider and the rice cake is automatically discharged as one lump even if the temperature of the mortar is not strict. This is convenient for the next step.
