SUMMARY OF THE INVENTION An apparatus for carrying out the present invention is designed so that after a pressing element presses an upper surface of an iron for a proper time,
In a pon rice cracker baking device which is instantaneously retracted upward, a pusher upward displacement permitting device for permitting upward displacement of the pusher to a desired dimensional gap is provided.

In the production of pond rice cracker, however, the present invention uses a lower die having a recessed hole and an iron die for covering the lower die which does not need to be engaged by a substantially flat upper die. At the same time, it is characterized in that the upward displacement of the pressing element for pressing the iron is appropriately permitted to a desired dimensional gap.

[0007]

[Operation] When the pusher is displaced upward to the predetermined size gap, the upper mold is displaced upward by the same size gap, and the steam generated in the dent chamber is generated by the pressure of the upper and lower molds. Although it is instantaneously discharged from the gap, the product material in the recessed chamber is not discharged to the outside in relation to the size of the size gap due to the upward displacement of the upper and lower molds, so that waste is prevented. In addition, in the roasting iron, the upper and lower molds are opened and closed each time the product material is supplied and the product is taken out.Since the upper and lower molds do not require meshing, strict alignment is not required Will be implemented.

EXAMPLES Specific examples of the present invention will be described below with reference to FIGS. The present invention is different from the structure of the rear surface of the previously proposed device shown in FIG. 1, and the front side of the heating unit is omitted because it is substantially the same, and FIG. 2 shows only the rear side. FIG. In the present invention, the structure of the contact portion between the locking member 11 and the support body 12 in FIG. 1 is improved, and a special pusher upward displacement allowance device is formed in this portion. That is, in the figure, 25 and 25 are projecting members fixed to the frame F, and two standing members 2 are provided on the upper surface of each.
6a and 26b are fixed to face each other. The upper ends of the two standing members 26a and 26b are connected to each other through the connecting plate 27 to form a pair of rectangular frames k and k (see FIG. 3), and the locking members are provided between the pair of frames. 11 is positioned. Reference numerals 28 and 28 denote adjusting operation screws screwed to the connecting plates 27, 27 so as to be vertically displaceable, and the tips of the adjusting operation screws are the two upright members 2 constituting each of the frames.
It is located in each groove h formed between 6a and 26b. Reference numeral 29 denotes a cylindrical support disposed immediately below the locking member 11, and a horizontal shaft 30 is provided in the center line direction thereof as shown in FIG. 3, and each end of the horizontal support 30 is fitted in the groove h, h. .
Reference numeral 31 is a U-shaped member fixed to the horizontal shaft 30 so as to be swingable around the shaft. Reference numeral 32 is a pneumatic cylinder fixed on a base plate 33 fixed to the frame F. The cylinder 32
Another U-shaped member 34 is fixed to the tip of the piston rod 32a of the above, and the lower end of this and the connecting rod 35 is attached to a shaft 36 as shown in FIG. 3, and the upper end of the rod 35 is connected to the U-shaped member 31. It is fixed to.

A projecting step 6a is formed on the side surface of the sprocket 6, and a pin 37 is planted on the side of the step. Further, the support member 38 standing upright from the frame F in the vicinity of the sprocket 6 is provided with a sensor 39 from which a contact 39a is projected, and the cylinder 32 is locked in association with the contact between the pin 37 and the contact 39a. It is adapted to be operated in synchronization with the member 11.

The production of pon rice crackers using the apparatus of the present invention constructed as described above is carried out, for example, as follows. First, as shown in FIG. 4 (a), 150 ° C. to 200 ° C.
The product material w such as dried sardines and vermicelli as a tie material is put into the recessed hole 41a formed in the lower mold 41 of the iron 40 that is heated to the upper mold, and the upper mold has a substantially flat shape. Close at 42. Then, the roasting iron 40 is placed at a fixed position on the heating plate 22 which is appropriately heated, and
To rotate. As a result, the pressing element 21 is displaced through a cam and a spring (not shown), presses the iron 40 with an appropriate pressing force (for example, 50 to 80 Kg / cm ² ), and after an appropriate time (for example, 1 to 3 seconds). The pressing force of the cam 5
Due to the presence of the notch part, it will disappear instantly.
Then, in one of such operations, the sensor 39 detects the operation of the pressing element 21 in association with the contact 39a and the pin 6a, and extends the pneumatic cylinder 32 before the pressing force of the pressing element 21 disappears, By this operation, the cylindrical support 29 is raised to the uppermost position regulated by the lower ends of the adjusting operation screws 28, 28 and the bulge shaft 30, and in this state, the cam 5 is rotated. It is in a state of being positioned slightly below the position of the lower surface of the buffer plate 11b of the locking member 11 pushed up to the uppermost position in the direction of arrow A. The gap s (see FIG. 5) between the cylindrical support 29 and the lower surface of the buffer plate 11b at this time is set to an appropriate size depending on the type and properties of the product material, and the adjustment is adjusted by the adjusting operation screws 28, 28.
Is performed by appropriately displacing vertically, whereby the pusher 21 is allowed to retreat upward depending on the gap s. When sardine is used as the product material as in this example, the gap s is 1/10 of
It is set so as to be freely displaceable in the range of mm to 2/10 mm. Therefore, as shown in FIG. 4 (b), the upper die 41 is about 1 due to the water vapor pressure generated in the recess 41 a.
In this state, the dry matter of the product material w is left in the recess chamber 41a, and almost only water vapor is released to the atmosphere. As a result, loss of product material is avoided as much as possible. Also, the water vapor in the recessed hole 41a explosively expands upon release, and the product energy w is crushed and expanded by the dynamic energy at this time, and the outer shape thereof conforms to the shape of the recessed hole 41a. Become. When a very short fixed time elapses, the pneumatic cylinder 32 is automatically shortened by the action of a timer or the like, the cylindrical support 29 is largely lowered, and the position regulation of the locking member 11 is relaxed, so that the pusher 21 is made large. Since it is displaced upward, the iron 40 is opened as shown in FIG. 4C and the product w1 is taken out.

In the above-described embodiment, when manufacturing a very thin pond rice cracker, the depth of the recessed hole 41a is set to, for example, about 1 mm. In this case, water vapor is discharged to the atmosphere, and the upper and lower molds 41, 42 are Since it is regulated by the wall surface, the flow direction tends to be horizontal, and the product material expands in the horizontal direction smoothly. Therefore, the product material reliably reaches the periphery of the recessed hole 41a. It is possible to obtain a pork rice cracker with a well-defined product shape.

EFFECT OF THE INVENTION According to the present invention, a pon rice cracker is used which uses a lower mold having a recessed hole and an upper mold which has a substantially flat lower surface and does not require meshing. Can be manufactured quickly and efficiently, that is, it does not require a fitting operation due to the unevenness of the upper and lower molds, and the vapor escape at the time of explosive expansion while finely adjusting according to the type and quantity of the material. Even an extremely thin product can have a good quality with a uniform wall thickness up to the periphery.

Further, as described above, in the case of using the iron for ironing which does not require the engagement of the concave and convex portions, the upper die is mechanically opened upward, so that the conventional manual work can be omitted. It can be used as an equipment, and it can be greatly enhanced to contribute to the improvement of productivity and the sale of inexpensive products.
