Abstract

PURPOSE:To obtain the titled apparatus capable of uniformly compressing the boiled rice, etc. mixed in a hopper, and discharging the rice constantly at a definite rate from the bottom, by attaching a forced compression transfer means to a part of the feeder and providing the feeder with a means to pinch and cut the extruded rice simultaneously from both sides. CONSTITUTION:The raw cooked rice is charged in the hopper 2, stirred, discharged to the gap between a pair of running compression belts 41a and 41b, and pressed with the belts. Prior to the drop of the pressed rice into the cylinder hole 61a, the cutters 5a, 5b placed above the hole 61a are closed toward their center instantaneously to pinch and cut the pressed rice. Accordingly, even highly glutinous rice can be divided without distortion, and can be put surely into the hole 61a. Since the gap between the running belts 41a and 41b becomes narrower at the lower side, the rice can be pressed and transferred forcibly. Accordingly, the cooked rice contained in the hopper 2 can be compressed uniformly, discharged at a defnite rate from the bottom of the apparatus, and subjected to a proper forming process such as topping with grated Japanese horseradish, pressing, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides food products that are molded using boiled rice as the main ingredient.
For example, the present invention relates to a device for quantitatively feeding raw materials in an apparatus that mechanically and continuously automatically forms food products such as nigiri sushi and onigiri misaki, which in principle are formed by one person manually.

The present inventor has already developed this type of quantitative dividing mechanism in 1983.
- We proposed the method described in No. 38175, but with this mechanism, there were cases where the rice could not be divided quantitatively due to insufficient compression of the highly viscous cooked rice. Includes raw materials! There were cases where the raw material blocks separated from the JFF l' were stuck in the falling direction and were not accommodated in the fixed cylinder hole.

The present invention was provided in order to eliminate the above-mentioned drawbacks, and its purpose is to provide a forced compression vertical feeding mechanism in a part of the feeding device, and simultaneously pinch the discharged raw material from both sides. This is achieved by providing a dividing mechanism.

The invention will now be explained in more detail according to the embodiments shown in the drawings.

After that, the shaping into sushi is completed.

Incidentally, the intermittent rotation speed L of the turntable (6) can be adjusted by appropriately combining the gear transmission mechanism and the intermittent movement mechanism such as a cam in the drive source section (DI) by known means, or by using a control circuit for the electric motorffff, l. - shall be stipulated.

It can be divided into two parts and accommodated properly in the cylinder hole (6N). In addition, since the rotating left and right belts (41 to 41) have gaps facing downwards and form a width, the raw material is forcibly conveyed downward while being compressed.Therefore, the hopper (2) Inside bar (22～～G
