Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention involves stretching a lump of bread dough obtained by kneading flour, water, yeast, and other bread ingredients or additives into a noodle strip shape. This relates to a bread forming machine that rolls up bread from one side and forms it into a cylindrical shape, such as French bread.

BACKGROUND OF THE INVENTION Conventionally, as a forming machine for forming the above-mentioned cylindrical bread dough, a pair of upper and lower rollers is disposed oppositely between a pair of opposing conveyor belt conveyors rotating in the same direction. It is known that a winding mechanism is provided downstream of the roller.

The bread forming machine described above is configured to stretch a lump of bread dough into a noodle strip through a pair of holes and a noodle strip, and roll it up into a cylindrical shape using a winding mechanism.

In addition, when forming bread dough with rollers, the bread forming machine has two methods: one method is to push the lump of dough directly into the dough, and the other method is to preform it using an auxiliary roller connected to the drive mechanism on the main body of the bread molding machine and then feed it. There is.

C1 Problems to be Solved by the Invention The above-mentioned molding machine in which the dough is manually pushed between the rollers is very advantageous in terms of miniaturization, but there is a problem in that it is difficult to clean the inside of the machine.

On the other hand, in a molding machine that pre-forms with an auxiliary roller connected to the drive mechanism on the molding machine main body side and then feeds it, a transmission mechanism is required for winding by a chain, belt, etc. that connects the molding machine main body and the drive mechanism. Since the dovetail transmission mechanism is also provided, the molding machine is necessarily large and heavy, making it expensive and also having the problem that cleaning the inside of the machine is difficult.

The present invention was made as a result of studies in view of the above-mentioned problems of the conventional technology, and is constructed by arranging mechanisms for stretching and rolling up bread dough, rolling, and conveying dough at appropriate positions. By doing so, it is possible to reduce the size and weight, and
To provide a bread forming machine in which the inside of the machine is easy to clean and hygienic, and furthermore, forming work can be conveniently performed while observing the flow state of bread dough.

2. Means for Solving the Problems In order to achieve the above object, the bread forming machine of the present invention has a belt conveyor formed by winding an endless forming belt around a driving roller and a driven roller. The drive roller and the driven roller are supported rotatably on a bed by respectively supporting the drive roller and the driven roller, and one side of the bed is inside a frame having an opening, with one end in the width direction facing the opening. with the other end fixed to the closed side of the frame, and a pair of left and right auxiliary rollers are arranged in parallel from upstream to downstream of the upper part of the belt conveyor, with a forming width formed in the middle. An auxiliary roller mechanism, a dough winding mechanism, and a rolling mechanism rotatably supported on the frame with the forming plate biased toward the forming belt side by a spring force are sequentially provided. The belt conveyor is characterized in that a rolling mechanism is disposed at the lower part of the belt conveyor, in which a rolling plate is connected to be able to move up and down by a lifting mechanism.

E1 Action When a lump of bread dough made by kneading flour, water and other additives is placed between a pair of auxiliary rollers that are rotating inward,
The bread dough is stretched through a bread dough forming width formed between both auxiliary rollers, and a belt-shaped bread dough is formed.

The belt-shaped dough thus formed is dropped and fed to the upstream side of the rotating belt conveyor, and is conveyed to the downstream side by the forming belt.

As the bread dough is conveyed by the belt, a winding mechanism stationary on the forming belt and the movement of the forming belt cause the dough to be rolled up between the two, and the bread dough is rolled up from one end into a cylindrical shape. While being molded, it is conveyed downstream by a belt conveyor.

The cylindrical bread dough formed in this way is fed between the forming plate of the forming mechanism and the forming belt as the forming belt advances, and in the process of passing between these, the bread dough is rolled up and formed, and then rolled by the forming belt. It is dropped and supplied upstream onto the rolling plate in the rolling mechanism.

Next, the cylindrical bread dough on the rolling pressure plate is rolled in the downstream direction on the rolling pressure plate as the forming belt advances, and is further formed into a cylindrical shape in the rolling process.

By performing such rolling, tightening, and shaping operations, the bread dough is formed into a spiral columnar shape with a predetermined diameter, and the dough is supplied onto the product receiver from the downstream end of the rolling plate.

Effects of the Invention Since the present invention is configured as described above, a lump of bread dough A is stretched into a belt shape by the auxiliary roller mechanism 14, and then formed into a cylindrical shape by the winding mechanism 16.
Furthermore, the forming mechanism 17 rolls and tightens the fabric to form it, and the rolling mechanism 37 rolls and forms the fabric. Rather, the dough that has been rolled up into a cylindrical shape by the winding mechanism 16 is rolled evenly from the outer periphery by the movement of the forming belt 10c as the forming belt 10c advances, and by applying pressure for forming, a step is created at the end of the winding. This eliminates the possibility of partial swelling due to the gas generated during fermentation and baking of the formed dough, making it possible to reliably obtain a well-shaped and high-quality product even after baking. is lifting mechanism 3
Since it can be raised and lowered by the lever 7b, it can be used for cylindrical dough having different diameters, and the pressure during rolling can be arbitrarily and properly controlled by the lifting mechanism 37b depending on the bread dough.

In addition, by arranging the auxiliary roller mechanism 14, the winding mechanism 16, the forming mechanism 17, and the rolling mechanism 37 in a concentrated manner around the belt conveyor 10, not only can the machine be downsized, but also the frame The flow state of the dough can be monitored through the opening 6 of the frame 1, which is very convenient for work management.
By being able to attach and detach the belt 10a, etc., any number of people can easily replace the belt 10a, etc., making cleaning easy and sanitary.

Furthermore, if the auxiliary roller mechanisms 14 are arranged in two stages, upper and lower, and the bread dough is pressurized in stages to stretch it to the required thickness,
This method has many advantages, such as the fact that the bread dough is not damaged as in the case where the dough is pressed and stretched at the same time, and a better product can be obtained.
