Of course, any other heating means can be used.

Reference numerals 70 and 80 in Figures 1 to 5 indicate the sealing means and grain supply, respectively.

The sealing pressurizing means 70 is for sealing the inlet 22 of the inner drum 20, and is composed of a sealing cover 71, a cylinder 72, and a cylinder support means 73.

The sealing cover 71 is in contact with the inlet 22 to prevent the grain (G) contained in the inner drum 20 to leak out. The sealing cover 71 may be any shape as long as it can block the injection hole 22, but is preferably formed in a conical shape inclined toward the injection hole 22 of the inner drum 20.

The reason is that the inclined not only maximizes the sealing effect by increasing the contact area with the inlet 22, but also when the space of the inner drum 20 is opened to allow the heated grain G to splash. This is to allow the heated air in the space 21 to quickly escape to the outside. The heated air may be guided to the curved surface of the sealing cover 71 to quickly exit.

The cylinder 72 reciprocates between a position where the sealing cover 71 is in contact with the inlet 22 and a position away from the inlet 22. As the cylinder 72, either a hydraulic cylinder or an air cylinder may be used, but a hydraulic cylinder having a strong pressing force is preferable.

The fixed hopper 81 is provided with an outlet 82 toward the lower side, and a rotating door 83 for opening and closing the outlet 82 is provided, and the rotating door 83 is opened and closed by an opening and closing cylinder 84. Can be activated. In addition, the inside of the fixed hopper 81 may be provided with a stirring device to stir and mix the grain (G) to be injected, the stirring device is a rotor 85 across the center of the hopper 81 and And a plurality of stirring blades 86 provided in the rotor 85 along its longitudinal direction, and a motor member 87 provided outside the hopper 81 to rotate the rotor 85.

And the outlet 82 is provided with a movable hopper 88 connecting the fixed hopper 81 and the inlet 22 of the inner drum 20, the movable hopper 88 is a chute connected to the outlet 82 (89) and a movable device (90) for operating the chute (89). The movable device 90 may be a cylinder installed under the fixed hopper 81.

Referring to Figures 1 to 5 the operation of the automatic splashing apparatus 1 according to the present invention configured as described above is as follows.

First, in order to fry or fry grains G using the automatic steaming apparatus 1, the cylinder 72 of the sealing pressurizing means 30 is operated to move the sealing cover 71 away from the inlet 22. Retreat to After retracting the sealing cover 71 to open the injection port 22 of the internal drum 20, the external drum 10 is rotated by a predetermined angle by the external drum rotating means 11 to inject the injection port 22 upward. To the side. Then, the movable device 90 is operated so that the lower end of the chute 89 is inserted into the injection hole 22. At this time, the upper portion of the chute 89 is positioned at the vertical lower portion of the outlet 82 of the fixed hopper 81.

After operating the chute 89 in this manner, the opening and closing cylinder 84 of the fixed hopper 81 is operated to rotate the outflow door 83 of the outlet 82 so that the grain G in the fixed hopper 81 becomes an internal drum. (20) to be introduced into the interior.

When the inflow of grain G is completed, the sealing cover 71 is moved by contact with the injection hole 22 by the cylinder 72 of the sealing pressurizing means 70 to seal the injection hole 22. When the sealing is completed, the outer drum rotating means 11 is operated to rotate the outer drum 10 again by a predetermined angle to be horizontal to the ground, and the inner drum 20 is rotated through the inner drum rotating means 70. .

Thereafter, the stirring body rotating means 50 is operated to allow the stirring body 40 to rotate relative to the inner drum 20. Specifically, the motor 52 is rotated to rotate the drive pulley 54 coupled to the output shaft of the motor 52, and this rotational force is transmitted to the driven pulley 56 by the belt 56. Since the driven pulley 56 is coupled to the support member 51, the support member 51 also rotates simultaneously with the rotation of the driven pulley 56. At this time, since the support member 51 is fixed to the stirring body 40, the stirring body 40 is rotated together with the rotation of the supporting member 51. The stirring body 40 is rotated in a state supported by the inner drum 20 stably by the bushing 58 of the carbon material.

Thereafter, the inner drum 20 is heated by the heating means 60 to fry the grain G.

While the grain G is heated, the stirring body 40 may rotate at the same speed as the inner drum 20, but may rotate faster or slower than the inner drum 20. When the rotational speed of the inner drum 20 is low, the grain G stays in a place in the storage space for a long time, so that the stirring body 40 rotates faster than the inner drum 20 so that the grain is rotated. It is preferable to stir, and when the speed of the inner drum 20 is higher than the inner drum 20 so as to easily separate the grain (G) attached to the inner peripheral surface of the inner drum 20 from the inner peripheral surface by centrifugal force It is preferable. In addition, the rotation direction of the stirring body 40 may also rotate in the same direction as the inner drum 20, but may also rotate in the opposite direction to the inner drum 20.

During the heating of the grain G to be fried, the air between the inner circumferential surface of the inner drum 20 and the inner circumferential surface of the support member 51 is formed between the outer circumferential surface of the support member 51 and the inner circumferential surface of the inner drum 20. The sealing member 59 does not escape to the outside of the splash apparatus 1. Moreover, the pressure in the inner drum 20 is grasped | ascertained by measuring the air pressure in the through-hole 51a with a pressure gauge.

As the heating proceeds, when the pressure of the inner drum 20 measured from the pressure gauge 57 reaches a desired level, the cylinder 72 of the sealing pressurizing means 70 is operated to open the sealing cover 71. The inner drum 20 is opened by retreating in the direction away from 22. As the inner drum 20 is opened, the air in the inner drum 20 is discharged from the inlet 22 with the sound of popping due to the pressure difference between the inside of the inner drum 20 and the outside of the inner drum 20. It is guided by the surface of the sealing cover 71 and quickly exits to the outside. In addition, the heated grain G in the inner drum 20 is splashed by the volume expansion of air due to the pressure decrease.

The frying apparatus according to the present embodiment described above does not burn easily in the inner drum while the grain is heated, unlike the prior art. The splashing apparatus according to the prior art adjusts the rotational speed of the inner drum so that grain does not burn, but as described above, it is easily determined that various conditions such as the type of grain, the amount of grain, and the temperature of the heating means must be considered. It was hard to do.

However, the apparatus for frying according to the present embodiment is provided with a stirring body on the inner drum so that the grain to be fried is not easily burned by stirring so that the grain to be fried does not stay in one position for a long time in the inner drum. This eliminates the need to precisely adjust the rotational speed of the inner drum, making it easy for the operator to adjust the grain to burn.

The bouncing apparatus according to the present invention as described above was forced to rotate relative to the agitator with respect to the internal drum by using a motor and a power transmission unit, but such a bouncing apparatus without a motor and a power transmission unit may be considered. That is, the object of the present invention can be achieved by simply placing the stirring body in the inner drum to be rotatable.

In detail, since the stirring body is not fixed to the inner drum, it is possible to stir the grains stored in the storage space while rotating freely in the inner drum separately from the rotation of the inner drum so that the grains do not burn easily on the inner drum.

On the other hand, the stirring body may be disposed in the inner drum in a free rotation state, it is also possible to rotate only the inner drum in a state in which the stirring body is fixed. As such, whatever the inner drum and the rotatable stirring body is disposed in the storage space, it belongs to the scope of the present invention.

Although the present invention has been described in detail with reference to embodiments and various modifications, the present invention is not necessarily limited to these embodiments and modifications, and various modifications may be made without departing from the spirit of the present invention. Can be.

According to the frying apparatus according to the present invention as described above, a stirring body for stirring the grain to be fried in the inner drum is provided so that it is not easily burned while the grain is heated by the heating means.
