There is one disclosed in Japanese Utility Model Publication No. 2-3080. As shown in FIG. 3, the food dispenser includes a cylindrical hopper 1 having a tapered portion 1a having a tapered lower portion on the lower side, and a delivery cylinder 3 rotatably connected to the lower side of the hopper 1. A portion rotatably supported by the frame 2, a lower end of the delivery tube 2 being opened outside the body frame 2, and a portion fitted to the delivery tube 2;
A helical delivery blade 4 provided with a series of portions having a large outer diameter that fits under the tapered portion 1a of the hopper 1
The first driving device 6 and the hopper 1 are fixed to the body frame 2 while rotating the delivery cylinder 3 by the delivery cylinder 3.
And a second driving device 7 that rotates at a lower speed than the delivery cylinder 3 in the same direction as the delivery cylinder 3 and the hopper 1.

In this food delivery machine, the delivery cylinder 3 is rotated by a first driving device 6 and the hopper 1 is independently rotated by a second driving device 7 in the same direction. By rotating at a low speed and setting the speed difference appropriately, the food such as baking paste in the hopper 1 is continuously discharged out of the delivery tube 3 at a delivery amount substantially equal to the delivery amount in the delivery tube 3. This makes it possible to continuously operate the food delivery machine for a long time without deteriorating foods whose physical properties such as feeding and pasting are easily deteriorated.

[0004]

However, in the above-mentioned conventional food delivery machine, when a hard paste or a large amount of viscous food is delivered, a gap is formed in a lower portion in the hopper, and the like.

According to a second aspect of the present invention, in the food delivery machine according to the first aspect, the driving device for rotating each of the divided portions includes one electric motor and different speeds from the electric motor to each divided portion. And a transmission mechanism for transmitting the driving force.

[0008]

According to a first aspect of the present invention, there is provided a food dispenser in which a tapered portion provided at a lower portion of a hopper is formed in several stages up and down, that is, three to three stages.
It is divided into about five stages, and these divisions are sequentially rotated at high speed from the upper division to the lower division by the driving device in the same direction. Even if the speed difference with the lower part that rotates integrally is large, the middle part is interposed between them, and the speed difference between the upper and lower adjacent parts is small. When a large amount of food such as paste is sent out, the rotation of each divided portion from the upper stage to the lower stage does not suddenly increase, but gradually increases.

[0009] Therefore, fixed to the machine frame is fitted inside the to the bottom of the delivery tube from the tapered portion of the hopper bottom, a spiral delivery blade diameter increases toward the upper side in the tapered portion, suitable speed difference In cooperation with each of the rotating parts as described above, even if the hopper and the delivery cylinder have a large diameter, food such as baking paste in the hopper can be delivered at a delivery volume substantially equal to the delivery volume in the delivery barrel. It can be sent out continuously to the delivery cylinder, without applying compressive force to the food, and the feeding of the food in the tapered part of the hopper can be uniformly sent out at each part in the vertical direction and can be sent down, Therefore, continuous operation can be performed for a long period of time without deteriorating food that easily deteriorates in physical properties (color, luster, viscosity, etc.) such as paste.

Further, of the divided portions obtained by dividing the tapered portion at the lower part of the hopper into several stages, the projecting ridges are projected at predetermined intervals in the circumferential direction on the inner peripheral surface of the second and lower divided portions and the delivery cylinder, respectively. These ridges are brought into contact with the outer periphery of the delivery blade, and the ridges are rotated integrally with the second and lower divided sections and the delivery cylinder, respectively. It is possible to prevent the formation of voids in the lower part of the hopper and in the delivery cylinder even with hard food by moving it closer to the center of the delivery cylinder. Can send food.

Further, in the food delivery machine according to the second aspect of the present invention, the driving force is transmitted to each of the divided portions at a different appropriate speed via a transmission mechanism by a single electric motor provided in the driving device. So, even if the division is about 3-5,
These can be rotated by one electric motor, so that the entire driving device can be made compact, and the rotation speed of each divided portion can be easily adjusted appropriately by the number of gear teeth of the driving mechanism.
