Description

TECHNICAL FIELD The present invention relates to a method and an apparatus for producing a fried rice cracker or fried hail by frying a rice cracker dough with oil.

[Problems to be Solved by Prior Art and Invention]

Conventionally, as a method for producing such fried rice crackers, in the case of mass production, a large amount of fried rice cracker dough is put in a large diameter basket and placed in a large-diameter kettle containing heating oil. It is a method of immersing it in a fried rice cracker and then inverting the basket and transferring it to a conveyor or the like. However, with this method, the amount of dough to be fried at one time was too large, and it was not possible to fried all the dough in the basket uniformly, resulting in variations in quality. Also, since the amount handled at one time was large, many fried rice crackers were damaged. Furthermore, the automated layout of such devices is linear and requires considerable space.

Moreover, for the production of a relatively small amount, small diameter baskets are handled and obtained, which is inefficient.

[Means for Solving the Problems]

As a result of various investigations in view of this, the present invention has developed a fried rice cracker production apparatus capable of producing a relatively large amount of food in a small space and capable of producing high-quality fried rice crackers.

By doing so, a fried basket reversing device that once applies the fried rice crackers in the fried basket to the wire mesh part and then discharges is provided, and the dough is fed into the fried basket at the dough feeding stage, and this is fed to the position of the fried kettle After making 3 turns and lowering the main shaft, the above dough is dipped in frying oil to make a fried rice cracker, and then the shaft is moved up and turned again in the same direction for 1/3 turn to make the frying placed on the take-out stage. Invert the basket and fried rice cracker inside Taken out, followed the same direction again
It is characterized in that the process of returning to the dough supply stage by rotating 1/3 is successively performed for each fried basket.

[Operation and Example]

Next, an embodiment of the present invention will be described with reference to the drawings. Since the following apparatus handles food, all members were made of stainless steel.

As shown in FIGS. 1 and 2 (A) to (C), the main shaft (3) is vertically moved by the frying basket cylinder (1) and is rotated by the frying basket rotation motor (2). 3, and further, as shown in FIG. 3, an arm (4) bent downward in the shape of a hook is attached to the upper end of the shaft (3) in a direction that divides the horizontal plane, which is the rotational surface, into three equal parts.
At the tip of (4), there was provided a fried cage support frame (5) which was curved in a semi-circular shape in the horizontal plane and was opened forward in the rotational direction.

Then, as shown in FIG. 3, through holes (6) are provided in the lateral direction further outside the line passing through the diameter (indicated by A in the figure) at both tip ends of these support frames (5), and these through holes ( 6) The pins (8) of the fried basket (7) shown in Fig. 4 (a) and (b) are shown below.
By engaging the fried basket (7) in the horizontal plane with the main shaft (3)
It was attached so that it could swing only so that only the front side in the direction of rotation was lowered. That is, this fried basket (7) consists of a peripheral edge (9) made of a band steel bent into a circular shape slightly smaller than the support frame (5) and a bowl-shaped bottom surface (10) obtained by processing a flat net downward into a spherical shape, The perimeter (9)

Then, the combustion exhaust gas was discharged into the atmosphere from an exhaust stack (19) provided on the side surface of the combustion chamber (18) surrounding the curved lower surface of the fryer (15). Also, when replenishing frying oil,
The frying oil always stored in (20) can be supplied to the pot by operating the manual cock (21). The temperature of the frying oil was automatically measured by a thermocouple installed in the frying oil and the burner (17) was turned on and off automatically according to the signal to keep the oil temperature constant.

Above the frying kettle (15), when the frying basket (7) descends into the frying kettle (15) as shown in FIG. A basket lid (23), which is raised and lowered by a lid cylinder (22) at the same speed as the fried basket (7) while closing the fried basket (7), is swingably provided in the same direction as the fried basket (7). Further, this basket lid (23) has a side that is raised when the basket lid (23) descends into the fryer (15) and is inclined, that is, the main shaft of the fryer (7).
(3) The following stirring fins (24) were provided on the lower surface of the basket lid (23) on the rear side in the rotation direction. That is, this fin is connected to the tip of the spline shaft (25) guided by the metal box (24) so that it can slide up and down smoothly through a universal joint (26), and further, the cage lid (23). Since it is attached to the bottom side, the lid (2
It moves up and down along with the up and down movement of 3) and becomes integral with the driven gear (27) on the upper part of the metal box (24) and the fin motor (2
It rotates by 8). Since the universal joint (26) is used twice, the basket lid is placed inside the fryer (15).
Even if (23) is greatly tilted, smooth rotation is possible. In the figure, (29) indicates a drive gear.

After the fried basket (7) is lifted again, the basket lid (2
The fins for stirring (2

The oil draining cylinder (31) having the tip (30) attached thereto was provided in the vicinity of the lid cylinder (22). This is for pressing the basket lid (23) downward to incline the basket for a certain period of time so that the fried rice crackers or the like and the remaining oil attached to the basket are naturally dropped.

Next, as shown in detail in FIGS. 6 (a) and (b), the wire mesh conveyor (32) is placed on the stage (16) for taking out the fried rice crackers.
And the following reversing device was provided.

That is, the fried basket (7) located above the take-out stage (16)
When it descends, it comes into contact with the tilt assisting member (12) at the central portion on the long circumference side of the peripheral edge (9) of the frying basket (7) and the frying basket is descended at that descending limit.
A state in which the peripheral edge (9) of the long side of (7) is floated from the support frame (5),
That is, the contact member (33) for holding the fried basket (7) in a state where the front side in the rotation direction of the main shaft is lowered is provided above the wire mesh conveyor (32). Further, a guide frame (34) above the wire mesh conveyor (32) for collecting products on the conveyor (32).
A circular plain weave wire mesh portion (35) having an area larger than the opening of the upper surface of the fried basket (7) and a hook (36) provided in the lower side from one end of the peripheral edge of the wire mesh portion (35) at the outer edge of ) Rotary actuator (37) with a discharging net frame consisting of
Was installed.

The discharging net frame and the rotary actuator (37) operate as follows to reverse the fried basket (7) and transfer the fried rice crackers etc. from the fried basket (7) to the wire mesh conveyor (32) below. It is a thing. That is, after the fried basket (7) is tilted as shown in FIG. 6 (a), the rotary frame (37) is rotated in the horizontal plane while the net frame is held horizontally as shown in FIG. 6 (b). As shown in Figures (a) and (b), the wire mesh part (35) is located above the top opening of the deep-fried food basket (7) with a slight gap, and the hook (36) is inclined. Engage with the bottom surface of the floating long side net. Then, in this state, the net frame is rotated by the rotary actuator (37) in the direction in which the short side of the peripheral edge (9) of the frying basket (7) is lowered, thereby rotating the frying basket (7) around its pin (8). Then, the fried rice cracker etc. inside is once applied to the wire net part (35) of the net frame and then dropped on the wire net conveyor (32) below, and then the rotary actuator (37) is used to move the net frame to the above. Perform the reverse operation to return to the original position. Bend one end of the wire mesh part (35) opposite to the position where the hook (36) of the wire frame is attached so that the fried rice crackers etc. will drop quickly from the wire mesh part (35) when the mesh frame is inverted. It was

Since the fried rice cracker manufacturing apparatus of the present invention has the above-described configuration, the entire apparatus can be arranged more compactly than the conventional one, which is very advantageous in terms of layout.

In the manufacturing apparatus configured in this way,
(3) is an arbitrary deep-fried basket (7), which is rotated from the dough supply stage (14) to the deep-frying pot (15) by 1/3 rotation at each end of the process, then lowered and held for a predetermined time, and then raised. After a lapse of a predetermined time again, it rotates 1/3 in the same direction. The first predetermined time is the time for frying the rice cracker dough in the kettle, and the second predetermined time is the time for performing the oil draining above the kettle.

The operation of the above-mentioned manufacturing apparatus will be described by taking the production of frying hail as an example.

First, the above-mentioned fried basket (7) is attached to each support frame (5) of the device. Then, a certain amount of frying oil is stored in the frying kettle (15) and fuel gas is ignited to heat the frying oil. After the temperature of the frying oil has risen to the set temperature, the dough to be fried is manually fed into the frying basket (7) located on the dough feeding stage (14). After storing a predetermined amount of dough in the fried basket (7), the main shaft (3) is rotated 1/3 to move the basket above the fried kettle (15) and drive the lid cylinder (22). While bringing the basket lid (23) into contact with the top opening of the fried basket (7), at the same time lowering the main shaft (3) by the fried basket cylinder (1)
Immerse (7) in frying oil. At this time, the fried basket (7) comes into contact with the inclined ring in the kettle, so that the front side in the rotation direction of the men shaft (3) is lowered. That is, since the basket lid (23) is in a state in which the side on which the stirring fins (24) are mounted is raised, the dough in the oil is gathered near the stirring fins (24) while being fried. Therefore, by driving the fins (24) in this state, the dough is randomly stirred, and variations in the dough do not occur in each dough, so that the fried dough with excellent quality can be obtained.

In this way, when the dough is fried over a predetermined time, the take-out process has already been completed and the dough supply stage (14)
The dough for fried hail is again supplied to the fried basket (7) moved to.

As described above, after the frying in the deep fryer (15) for a predetermined time, the main shaft (3) is raised again and the oil draining cylinder is driven to drive one end of the basket lid (23) with the rod. By pressing the portion, the frying basket (7) together with the lid is inclined so that the front in the rotational direction is lowered, and excess oil is dropped back into the pot to prevent excessive reduction of the oil.

Then, after a lapse of a predetermined time, the oil removing cylinder is returned, and the main shaft (3) is rotated again by 1/3 to take out the fried basket (7) and move it to the stage (16). At this time, the fried basket (7) that previously stored the dough is moving above the fried kettle (15), and while the fried basket (7) is in the removal process, the previous dough is stored in the fried kettle (15). Will be fried in oil.

The fried basket (7) moved to the take-out stage (16) is tilted by lowering the main shaft (3) so that its tilt assist member hits the abutment member (33) and is reversed by the reversing device. Fried hail is a wire mesh conveyor
(32) It falls on.

And when the fried basket (7) is inverted, it does not drop onto the lower wire mesh conveyor (32) at a stretch, and first hits the wire mesh portion (35) of the reversing device, so the speed of the drop weakens and the wire mesh conveyor (32) ) Can be minimized damage to the hail. Further, because of the wire mesh portion (35), the hail discharged from the fried basket (7) is collected on the wire mesh conveyor (32) without scattering in all directions. The wire mesh conveyor (32) can be constantly operated so that the fried hail dropped from one cage (7) can always be quickly moved to the tip of the conveyor and sent to the next step, but one fried cage ( If the conveyor (32) is operated only for the length of the conveyor occupied by the hail that falls due to each reversal of 7), the power consumption of the conveyor (32) can be saved and the frying on the conveyor can be performed. It takes a considerable amount of time for the hail to move to the tip of the conveyor, so that extra oil can be drained during that time.

And after returning the discharging net frame to the original position by the rotary actuator (37), the fried basket (7) which has discharged the fried hail by reversing waits for the end time of the process in the deep fryer (15) for lifting the dough. Then, further rotate 1/3 to return to the dough supply stage (14).

By repeating the above operation sequentially for each fried basket, fried arare can be efficiently and automatically manufactured.

If the target product is considerably larger than the hail, for example, a circular rice cracker, a circular frying exclusive frame (38) as shown in Fig. 8 (a) and (b) is used. That is, a flat bottom surface (39) made of a net or punching plate and a peripheral edge made of a band steel bent in a circular shape.
It is a tray shaped in (9) and a small round tray (40) of a size that can hold the target circular rice crackers one by one inside.
Are provided in large numbers. Further, pins (8) and (8) are projectingly provided outside the peripheral edge (9) at a position where the peripheral edge (9) is divided into two by a straight line which does not pass through the center of the circle, like the fried basket (7). ,
And a protrusion (1) at the center of the long side of the circumference divided by the pin (8).
3) is provided.

And such a dedicated frame (38) puts the pins (8) (8) in the third position.
Insert it into the through hole (6) of the support frame (5)
By locking 3) to the upper end surface of the support frame (5), the support frame (5)
Attach to. In the case of this special frame (38), fried basket
The tilt assisting members (11) and (12) as in (7) are not necessary. Since the bottom surface is flat, the tilting ring in the fryer (15) can directly contact the bottom surface, and the contact member (33) can directly contact the bottom surface when reversing at the take-out stage. Is.

〔The invention's effect〕

As described above, according to the present invention, when producing a large amount of fried rice crackers, fried rice crackers, etc., since the fried basket is arranged on a circular orbit, each process is arranged in a circular shape and is compact in the device layout, and It is efficient. Furthermore, there is no variation in the fried food, you can obtain excellent quality products, and if you prepare various fried baskets according to the size and shape of the fried rice crackers, even if the target product changes frequently It has remarkable effects such as being able to deal with it.
