Abstract
Description
Technical Field
[0001] This invention relates to a pasta production equipment, and more particularly to a steamed bun fermentation and forming machine. Background Technology
[0002] Steamed buns are a common type of wheat-based food. They are made primarily from wheat flour, with yeast, salt, and other ingredients added to form a dough. The dough is then processed through kneading, proofing, dividing, shaping, and steaming. Currently, most steps in the steamed bun production industry are performed by workers, resulting in a low level of automation. This hinders overall production speed and makes it difficult to standardize bun sizes. Therefore, to improve production efficiency and standardization, the steamed bun production industry needs to develop equipment with automated shaping and fermentation processes.

The lower opening of the dough feeding hopper is directly opposite the gap between the two extrusion rollers. During the rotation of the extrusion rollers, dry powder can be continuously coated from the powder storage box.
[0006] The first conveyor belt group is composed of several first conveyor belt units arranged side by side at intervals. The first conveyor belt group is located below the dough extrusion mechanism and extends to the rear. The dough extruded from between the two extrusion rollers will hang onto the first conveyor belt group under gravity and be conveyed to the rear with it. The conveying speed of the first conveyor belt group is matched with the extrusion speed of the dough extrusion mechanism. A support plate is fixed at the bottom of the upper half of the first conveyor belt group, and a drop hole is provided on the rear half of the support plate.

[0008] The slitting mechanism is located behind the dough extrusion mechanism. It includes a relatively fixed support, a roller shaft that is horizontally rotated and mounted on the support, and several rollers that are fixed at equal intervals on the roller shaft. The axial direction of the roller shaft is perpendicular to the conveying direction of the first conveyor belt group. The positions of the rollers correspond to and are close to the two sides of the first conveyor belt unit. The support is equipped with a motor for driving the roller shaft to rotate.
[0009] The cutting mechanism is located behind the slitting mechanism. It includes a first horizontal slide table parallel to the first conveyor belt group, a sliding frame that moves with the first horizontal slide table, a lifting frame that is vertically slidably mounted on the sliding frame, and a cutting blade provided on the lifting frame.

[0016] Therefore, the present invention has the following characteristics compared with the prior art: 1. The dough extrusion mechanism in the present invention is used to extrude the kneaded dough to a fixed thickness. The extruded dough is then hung on the first conveyor belt group and moves backward with it. The powdering mechanism can sprinkle powder on the upper surface of the first conveyor belt group and the upper surface of the dough to prevent the dough from sticking together. The slitting mechanism can cut the dough into strips, and the dough located in the outer area of the first conveyor belt unit will fall from the drop hole. Then the cutting mechanism can segment the slitting dough. After the segmented dough is transferred to the second conveyor belt group, it will automatically separate back and forth. The third conveyor belt on the dough fermentation mechanism can receive the dough from the second conveyor belt group. After it is filled, the lifting frame changes its height until all the third conveyor belts are filled. Then it is left to stand and wait for fermentation, realizing automated forming and fermentation; 2. The support base is provided with two horizontal slide rails, and each of the two horizontal slide rails is slidably fitted with a mounting seat. The two extrusion rollers and two powder storage boxes are respectively set on the two mounting seats. In this way, the distance between the two extrusion rollers can be freely adjusted to change the thickness of the dough. Attached Figure Description

[0031] See Figure 3 and Figure 6 The slitting mechanism is located behind the dough extrusion mechanism.

[0036] The working principle of this embodiment is as follows: The processed dough is placed into the dough feeding hopper. The dough needs a certain degree of fluidity. Under its own weight, the dough will flow out from the lower opening of the dough feeding hopper and be drawn in by the first and second extrusion rollers. The two extrusion rollers not only have an extrusion effect but also a traction effect, which can continuously pull out the dough sheet from the dough feeding hopper. During the continuous rotation of the two extrusion rollers, they will also continuously coat themselves with flour from the flour storage box to keep themselves dry and prevent the dough from sticking. The flour scraper can make the flour on the extrusion rollers evenly distributed, so that the dough sheet extruded from the dough sheet extrusion mechanism has a uniform thickness and is transferred to the first conveyor belt group. The two flour sprinkling mechanisms can sprinkle flour on the upper surface of the first conveyor belt group and the upper surface of the dough sheet to ensure that the top and bottom of the dough sheet remain dry and prevent it from sticking to the equipment. Then, the roller cutter on the slitting mechanism can cut the dough sheet. At this time, the dough sheet is... The dough is cut into 5 wide strips and 6 narrow strips. The narrow strips are guided by guide wheels to fall through the drop hole area for easy recycling. The wide strips are cut into equal length segments by a cutting mechanism. The first horizontal slide moves the sliding frame at the speed of the first conveyor belt group. After the lifting frame descends to complete the cutting action, the lifting frame and the first horizontal slide are reset. The cut dough is then received by the second conveyor belt group. Because the second conveyor belt group is faster, the dough that was originally connected end to end will be separated, and the dough will also be stretched to a certain extent. Finally, the dough is received by the third conveyor belt in the dough fermentation mechanism. After the third conveyor belt is filled, it stops rotating. With the help of the lifting component, all the third conveyor belts will be filled, and then the dough is left to ferment.
[0037] It will be apparent to those skilled in the art that the present invention can be modified in various ways, and such modifications are not considered to depart from the scope of the invention. All such modifications that are obvious to those skilled in the art are included within the scope of the claims.
