Description

[Detailed description of the invention] Industrial application field The invention involves kneading glutinous rice flour with hot water and flavoring agents such as sugar, stretching it to a predetermined uniform thickness, and then shaping it into a rectangular shape of a predetermined size. The seed material is cut into small pieces such as 100 yen, etc., and before it dries, it is sandwiched between a pair of heating plates with flat facing surfaces and intermittently pressurized at appropriate timing and pressure (so-called tightening). By baking the seed material while heating (or squeezing), the seed material is baked between the pair of heating plates so that the particle density is uniform throughout without creating any cavities inside. This invention relates to a baking device for making so-called yaki-yaki rice crackers, which are manufactured by expanding the rice crackers into flat, circular finished rice crackers with uniform thickness.

Conventional technology Conventionally, the above-mentioned glutinous rice crackers are baked by using a fixed lower heating plate with a flat plate surface, and an upper heating plate with a flat plate surface corresponding to the fixed lower heating plate. The hinges are connected so that they can be rotated to open and close around one end edge, and the upper heating plate is rotated and pressed to close around the hinge connection part so that the plate surfaces face each other toward the lower heating plate. Using a baking device equipped with a screw, a plurality of seed materials are inserted at intervals between the surfaces of both the lower and upper heating plates of the device, and the materials are heated. Keep the upper and lower surfaces of the heating plate in contact with the surfaces of both heating plates, and in this state, by manual operation of the above-mentioned screw, the temperature will initially be fast and weak, then it will be slow and strong, and then it will be slow near the completion of the final firing. As mentioned above, while checking the degree of baking, intermittently press the upper heating plate towards the lower heating plate to tighten the seed material at the appropriate timing and strength. It was made by hand in this way. In this baking process, the intermittent pressing operation with the above-mentioned screw at the appropriate timing and strength is the most important and difficult task in order to bake the desired glutinous rice crackers with uniformly high quality in terms of quality and shape. However, this was done based on intuition, required considerable skill, was extremely hard work, and was inefficient. In this case, the baking device rotates and presses the upper heating plate towards the lower heating plate in a closed manner around the hinge connection part, so that there is There were also problems such as the spacing and pressure being difficult to maintain uniformity throughout, causing the seeds to shift during the pressing operation, and multiple rice crackers being baked at the same time to be of different thickness and quality. .

Problems to be Solved by the Invention In view of the above circumstances, the present invention provides a device that can mechanically, automatically, and efficiently carry out the baking work of glutinous rice crackers, which was conventionally done by hand, as described above. This is what I am trying to do.

Means for Solving the Problem The device for baking glutinous rice crackers according to the present invention consists of a fixed heating plate and a movable heating plate arranged vertically opposite each other for baking the glutinous rice crackers with seeds for the glutinous rice crackers sandwiched between them. and elastic biasing means for biasing the movable heating plate to elastically move the movable heating plate away from the fixed heating plate at a predetermined distance, and resisting the biasing force of the elastic biasing unit. and a pressurizing mechanism that intermittently presses and approaches the movable heating plate toward the fixed heating plate, the pressurizing mechanism fixing one side and connecting the other side to the movable heating plate. A device is provided in which an electromagnet made movable by a motor and an attraction member for the electromagnet are arranged opposite to each other at a distance from each other, and a device is provided for intermittently supplying excitation currents of DC voltages of different magnitudes to the electromagnet in a desired order. That's what happens.

According to this configuration device, seeds for a plurality of sticky rice crackers are supplied at intervals between a fixed heating plate and a movable heating plate, and the seeds are fixedly heated on the movable heating plate by an elastic biasing means. When elastically separated from the disk to a predetermined distance position, it is possible to maintain the upper and lower surfaces of both heating disks in contact with the disk surface, and in this state, the electromagnet is activated by the pressurizing mechanism. Due to the intermittent suction action of the suction member caused by the intermittent supply of excitation current of DC voltage to the In this way, the various materials sandwiched together can be pressed intermittently all at once. In this case, the excitation current of DC voltage can be intermittently supplied to the electromagnet in the desired order at arbitrarily different magnitudes and speeds, and by setting this appropriately, the fixed heating plate can be The intermittent pressurizing movement of the movable heating plate toward the opposite side can be automatically performed with strength and timing suitable for baking the yakisenbei rice crackers. In this case, the pressurized approach operation is performed against the urging force of the elastic urging means, and since the elastic urging means plays the role of a returning action, it can be made elastically soft and smooth. As a result, the desired process of baking the glutinous rice crackers can be carried out automatically and efficiently.

The supplied seeds are scraped off by the product receiver 17 provided on the front side of the heating platen 3, and then dropped onto the plate surface 3a of the fixed heating platen 3 by turning the scraping plate 15 face down. The supply plate 14 can be returned to the withdrawn position without the risk of scraping material. Further, the supply plate 14 has an operation member consisting of one lever for aligning and misaligning the through holes of the upper and lower mold plates 14a and 14b, and for raising the scraping plate 15. 16 is provided to also serve as a means for advancing and retracting the supply plate.

The movable frame 5 has a pair of left and right supports 7,
A lower cross bar 10 is installed horizontally in the middle of the fixed frame 2 and crosses the middle of the fixed frame 2, and a suction member 26 constituting a part of the pressurizing mechanism described later is attached to the lower cross bar 10. There is. The lower crossbar 10 has a pulley 1 mounted on the upper part of the fixed frame 2 above it.
One end of the cable 20 hanging down through 8 and 19 is connected to the pulleys 18 and 19 on the opposite side to the connection side.
A balance weight 21 is attached to the other end of the cable 20 that hangs down through the cable. Here, the balance weight 20 has a weight that is balanced with the entire weight of the movable frame 5 including the movable heating plate 4, suction member 26, and other accessories. As a result, the movable heating plate 3 moving away from and approaching the fixed heating plate 3 can be moved up and down integrally with the movable frame 5 easily, and the vertical movement can be stopped at any desired height position. It's summery.

Immediately above the balance weight 21, an elastic biasing means 22 made of rubber, a spring, or the like is provided. This elastic biasing means 22 is configured so that when the movable heating plate 4 is lowered, its plate surface 4a is fixed to the plate surface 3a of the fixed heating plate 3.
The upper surface of the balance weight 21, which rises accordingly, comes into contact with the upper surface of the balance weight 21 when it is approached to a predetermined distance position suitable for just contacting the upper surface of the seed material supplied and placed thereon. It is attached to the fixed frame 2 at a certain position. Therefore, the elastic biasing means 22
is elastically biased against the fixed heating plate 3 to the above-mentioned predetermined spacing distance position, and the further downward movement of the movable heating plate 4 toward the fixed heating plate 3 from that spacing distance position is performed. Its elasticity allows it to be elastically received into an acceptable state. The elastic biasing force or height position of the elastic biasing means 22 can be finely adjusted by operating an attached handle 23.

This device is intermittently pressurized so that the movable heating platen 4 is moved downwardly closer to the fixed heating platen 3 from the above-mentioned predetermined distance position against the urging force of the elastic urging means 22. A pressurizing mechanism 24 is provided for the approach. The pressurizing mechanism 24 includes an electromagnet 25 and an attraction member 26 made of a magnetic material.

31', 31'' and a bridge rectifier type rectifier circuit 32,
32', 32'', and an electric circuit that supplies an excitation current of DC voltage to the electromagnet 25. With this configuration, one rotation time of the rotating shaft 28 can be reduced to 1
The setting is made in accordance with the time suitable for baking a batch of sticky rice crackers, and for each control cam, the pitch of the protrusion 29a of the first working cam 29 is finely set, and the pitch of the protrusion 29'a of the next working cam 29' is set. The pitch of the protrusion 29''a of the cam 29'' that operates last is set slightly coarsely, and the electric circuit connected to each switch 30, 30', 30'' that engages with each of these cams is set to operate first. Adjust and set the switching transformer 31 of the electrical circuit to reduce the voltage, adjust and set the switching transformer 31' of the next working electrical circuit to slightly increase the voltage, and adjust the switching transformer 31' of the electrical circuit that will work last. 31'' to increase the current, at first a small voltage current is quickly and intermittently supplied to the electromagnet 25, and then a slightly larger voltage current is supplied somewhat slowly. is intermittently supplied, and finally a large voltage current is slowly and intermittently supplied, so that the attraction of the attraction member 26 due to the excitation of the electromagnet 25 in accordance with the supply of such excitation current. As a result of the action, the movable heating plate 4 resists the elastic biasing means 22 and is first weakened quickly, then strengthened slightly slowly, and finally strengthened slowly, which is suitable for baking rice crackers. Fixed heating plate 3 intermittently at desired timing and intensity.
The action of pressing the seed material sandwiched between the two board surfaces 3a and 4a by pressing the seed material toward the board surfaces 3a and 4a can be automatically realized. In this configuration, each control cam 2
9, 29', 29'' to each protrusion 29a, 29'a, 2

The seed material is supplied onto the plate surface 3a of the fixed heating plate 3. Then, the movable heating plate 4 is lowered. Then, the upper surface of the balance weight 21
The movable heating plate 4 fixes the plate surface 4a of the heating plate 4 by the elastic biasing means 22.
In this state, the upper and lower surfaces of the seed material are aligned with both opposing board surfaces 3a, 4a.
It will be in a state where it is in contact with and is sandwiched without receiving any pressure. In this state, the electromagnet 25 is activated by the excitation current supply device 27 described above.
is intermittently cold-magnetized to attract the attraction member 26,
A force acting to compress the elastic biasing means 22 resists the biasing force of the elastic biasing means 22, and the movable heating plate 4 is intermittently pressed toward the fixed heating plate 3, so that the seed material is intermittently supplied. Pressed by In this case, the return action in the intermittent pressure approach is given by the elastic biasing force of the elastic biasing means 22, and therefore the intermittent pressure approach operation can be performed flexibly and elastically. The pressurized approach operation is performed on the plate surface 4a of the movable heating plate 4.
Since this is done parallel to the plate surface 3a of the fixed heating plate 3, the plurality of sandwiched seed materials can be pressed uniformly without shifting. As a result, the seeds are intermittently pressed and baked into a glutinous rice cracker product.
At the end of this baking, the movable heating plate 4 is raised and returned to the original remote position, and the next seed material is supplied by the seed material supplying device 12, and the baked glutinous rice cracker product is fixedly heated accordingly. Board surface 3a of board 3
The product is collected from above into the product receiver 17, and the same operation is repeated thereafter. In this way, the baking work of the roasted rice crackers can be carried out automatically and efficiently.

In addition, unlike the illustrated example in which the electromagnet 25 is fixed and the suction member 26 is connected to the movable heating plate and made movable, the position is reversed, and the electromagnet 25 is connected to the movable heating plate 4. The suction member 26 can be made movable and the suction member 26 can be fixed, and the installation position thereof can be set as appropriate, such as by providing it in a close position that has a direct interlocking relationship with the movable heating plate 4. It is something. Further, the elastic biasing means 22 is not limited to being provided at a position where the balance weight 21 comes into contact as in the illustrated example;
For example, it may be interposed between the fixed heating plate 3 and the movable heating plate 4, or it may be interposed between the fixed frame 2 at the supports 7 and 8 of the movable frame 5, etc. It can be installed at an appropriate position.
