Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a manufacturing apparatus for automatically twisting and pleating the skin of Chinese steamed buns and the like.

[Conventional technology]

Traditionally, Chinese buns have twist pleats on the skin, but traditionally they were all handmade and were cumbersome, so recently Chinese buns without twist pleats have become popular.

Also, recently, automatic wrapping machines are increasingly used to make manju dough, but even this type of machine cannot create twist pleats.

However, in JP-A-59-183655, an apparatus for manufacturing manju with twist pleats was proposed.

[Problem that the invention seeks to solve]

However, although the above proposal does have twist pleats, the twist pleats are only placed below the shoulders of the bun, and the skin remains raised at the top.
Furthermore, even with the claw rotation device and the head holding device, no twist can be applied to the top.

Therefore, there has been a need for an apparatus that can automatically produce Chinese steamed buns with twist pleats similar to those made by hand, which have twist pleats not only below the shoulders of the bun but also at the top.

[Means for solving problems]

Therefore, the present inventor achieved the objective by providing both a twisting and pleating claw for the lower part of the manju dough and a twisting and pleating claw for the top.
The invention has been completed. That is, the present invention provides a rotatable and vertically movable center shaft having three rotatable claws (hereinafter referred to as "middle claws") at the tip, and claws (hereinafter referred to as "middle claws") at each tip at equal intervals around an outer shaft built into the center shaft. (hereinafter referred to as the external nail)
This is a bun twisting and pleating device consisting of three or more fingers that can move up and down.

The present invention will be explained in detail below with reference to the drawings.

FIG. 4 is a diagram showing the main parts of ancillary equipment into which the twist pleating device of the present invention shown in FIGS. Then, the holder 10 is lowered from the dotted line position to the solid line position, and at the same time, three or more fingers 1, which have external claws 2, 2', etc. at their lower tips, are lowered.
1'... is coming down. In this case, each finger descends in a closed state around the outer shaft 3 as shown in FIG. The outer claws 2, 2'... dig into the manju dough. Each finger 1, 1' is centripetally biased near its upper end by a biasing means such as a spring. The shape of the outer claw is a spiral shape toward the center, forming twist pleats 31 as shown in FIG. The number of fingers is 3 or more, preferably 6 or more, but depending on the size of the stem and the size of the bun, the maximum number of fingers is 3 or more, preferably 6 or more.
The limit is about 12 pieces. In FIG. 4, reference numeral 12 denotes a holder for the outer shaft 3, which is movable up and down together with the outer shaft 3 by a hydraulic cylinder device (not shown) or the like.

When the outer claw digs into the manju dough and creates twists and folds, the center of the dough rises and forms the top. Here, as the guide 5 rises, each finger rises while opening its lower end due to the pulley and the fulcrum (FIG. 1).

At the same time as each finger rises, the three inner claws 4 attached to the lower end of the center shaft 3' come down and bite into the top of the rising manju dough up to a maximum of 120 degrees in the opposite direction to the twisted pleats of the outer claws. The rotation creates twist pleats 32 at the top. After this,
The middle claw 4 is raised, thus completing the twisting and pleating of the bun.

The twist pleating device of the present invention can be operated manually or automatically, and is particularly suitable for vertical movement, opening/closing movement,
If each operation such as rotation is performed using a timer, twisting and pleating can be done smoothly and quickly.Furthermore, if you combine it with a belt conveyor feeding device for manju dough, you can easily make many buns at once using the normal method. Mass production is also possible.

Although the present invention has been explained using Chinese steamed buns as an example, it can also be applied to twisting and pleating bread, Japanese sweets, etc., and has a wide range of applications. At that time, depending on the size of the object in each case, the pattern, number, size, etc. of the twist pleats may be changed as appropriate by changing the shape, number, etc. of the outer claws and inner claws.

〔Effect of the invention〕

The twist pleating device of the present invention makes it possible to make twist pleats both below the shoulders and at the top of the bun, which has not been done in the past. Furthermore, it became possible to mass produce the product, and the product value was further improved as it resembled a reproduction of the hand-made twisted and pleated manju of the past.
