Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and in particular to a double-layer double-pressure dough pressing mechanism for food processing. Background Technology

[0002] In the food processing industry, noodle presses are one of the core pieces of equipment for noodle production, and are widely used in homes, catering establishments, and food processing plants.

[0003] Application number CN202510661704.1 discloses a fully automatic noodle-pressing production line, belonging to the technical field of food processing equipment. It includes a feeding conveyor, a feeding calender, a feeding inclined slitting machine, a fully automatic noodle-pressing machine, and a telescopic noodle-pressing docking machine connected in sequence. The fully automatic noodle-pressing machine includes an adjustment mechanism for automatically adjusting the thickness of the pressed dough. The adjustment mechanism is driven by a servo motor, which is controlled by a PLC. Compared to manual adjustment, this is not only more time-saving and labor-saving but also has better precision. Furthermore, the distance between the pressure rollers and the conveyor rollers can be adjusted as needed during processing to meet different processing requirements. The number of pressing cycles and the thickness of each pressing cycle can be set through the control terminal to achieve a customized pressing mode, greatly improving the applicability of the equipment.

[0004] Based on the above patent searches and understanding of the application of existing pressing and stacking instruments: 1. Most existing fully automatic dough pressing machines are single-layer pressing machines, which complete a single pressing operation with only one set of pressing rollers. They cannot achieve continuous multi-layer pressing, resulting in low production efficiency and difficulty in meeting the batch production needs of food processing plants. Furthermore, single pressing cannot make the internal structure of the dough fully compact, resulting in a loose texture and insufficient toughness of the dough. 2. During the processing, the dough is prone to tailing and deviation due to conveying inertia. The dough conveying link lacks a precise limiting structure, which easily causes lateral deviation beyond the conveyor belt range. Furthermore, the dough is prone to sticking together due to its own stickiness during multiple stacking and conveying processes, affecting subsequent dough forming and process progress, resulting in poor overall processing quality stability.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a double-layer double-pressure dough pressing mechanism for food processing, in order to achieve a more practical purpose. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a double-layer, double-press dough pressing mechanism for food processing. This addresses the issues of existing fully automatic dough pressing machines, which mostly operate on a single-layer pressing mode, relying solely on a single set of pressure rollers for each pressing operation. This results in low production efficiency due to the inability to achieve continuous multi-layer pressing, making it difficult to meet the batch production needs of food processing plants. Furthermore, single pressing cannot fully compact the internal structure of the dough, leading to a loose texture, insufficient elasticity, and a tendency for the dough to wobble and deviate during feeding due to conveying inertia. The lack of precise limiting structures in the dough conveying process also causes lateral deviation beyond the conveyor belt's range. Additionally, the dough tends to stick together during multiple pressing and conveying processes due to its own adhesiveness, affecting subsequent dough forming and process advancement, resulting in poor overall processing quality stability.

A sprocket is located on the left side of the low-pressure head cooperating roller A302. The low-pressure head cooperating roller B303 is rotatably connected to its interior upper front position.

The adaptive limit roller 304 is located in front and below the low-pressure head cooperating roller A302.

[0035] Among them, a powder spreader B305 is installed at the top rear of the low-pressure noodle press unit 3. The powder spreader B305 is located at the top front of the second conveyor belt 103. The second conveyor belt 103 is located at the rear and above the low-pressure head roller 301. The low-pressure head roller 301 and the low-pressure head cooperating roller A302 are located at the top front of the third conveyor belt 104. The adaptive limit roller 304 is located in front of the third conveyor belt 104.

[0036] When using: The dough is placed from the front or left side of the fourth conveyor belt 105. The fourth conveyor belt 105 starts and moves the dough backward. During the feeding process of the dough from the side of the fourth conveyor belt 105, the fourth conveyor belt 105 is conveyed backward, which makes it easy for the dough to swing its tail. The inertia of the tail swing can easily cause the dough to deviate from its position. Therefore, with the cooperation of the side limit wheel group 151, the position of the dough is limited and buffered, and the position of the dough is adjusted in time. In addition, the position of the photoelectric sensor 121 can detect the size of the dough in time and stop the fourth conveyor belt 105 to avoid blockage during the process of the fourth conveyor belt 105 conveying the dough to the high head roller B202 and the high head mating roller 204 to squeeze it into dough. Shaping and transport: After the dough moves to contact the high-head roller A201, the drive motor A107 drives the high-head roller A201 to rotate, causing the dough to move upward. The high-head rollers A201, B202, and C203 rotate in the same direction. The dough is squeezed into a sheet between the high-head roller B202 and the high-head roller 204. Under the limit of the high-head roller C203, it is transferred to the upper rear end of the first conveyor belt 102. The first conveyor belt 102 then conveys the sheet forward. Through the above steps, the shape of the dough can be initially positioned and modified.

[0037] First fold: When the dough is conveyed from the front end of the first conveyor belt 102 to above the second conveyor belt 103, the second conveyor belt 103 initially conveys it backward, causing the front end of the dough to fold backward. When the middle position of the dough reaches above the second conveyor belt 103, the servo motor controls the second conveyor belt 103 to convey it forward, running in the same direction as the first conveyor belt 102 to complete one fold. Then, the second conveyor belt 103 conveys the folded dough to the top of the low head roller 301.

[0038] First pressing of dough: After being folded, the dough sheet is limited by the short head cooperating roller B303 and enters the space between the short head rotating roller 301 and the short head cooperating roller A302 to complete the first pressing process. Then, the dough sheet falls onto the third conveyor belt 104 and is conveyed to the rear by the third conveyor belt 104.

[0039] Second fold: When the third conveyor belt 104 conveys the dough, the fourth conveyor belt 105 is controlled by a servo motor to convey it forward, facing the third conveyor belt 104. After the front end of the dough contacts the fourth conveyor belt 105, it moves forward. When the middle of the dough reaches the fourth conveyor belt 105, the servo motor controls the fourth conveyor belt 105 to convey it backward, running in the same direction as the third conveyor belt 104. When the dough is completely separated from the third conveyor belt 104 and is entirely on the fourth conveyor belt 105, the second folding is completed.

[0040] Secondary pressing and discharge: The fourth conveyor belt 105 transports the double-folded dough sheet back to the position of the high head roller A201. After being transferred to the first conveyor belt 102 by the high head roller group and the high head cooperating roller 204, the dough sheet is repeated to enter the low-pressure dough press unit 3 for the second time. Under the guidance of the low head cooperating roller B303, the dough sheet is pressed again by the low head roller 301 and the low head cooperating roller A302. After being pressed twice, the dough sheet is transported backward by the third conveyor belt 104. After contacting the adaptive limit roller 304, it is transferred downward to the top front end of the fifth conveyor belt 106 under its limiting action. The fifth conveyor belt 106 transports the double-folded and double-pressed dough sheet to the subsequent process.

[0041] In the above process, the function of powder spreader A152 and powder spreader B305 is to deliver powder in time before the dough becomes viscous during the double-layering and double-pressing process, so as to avoid subsequent adhesion and affect the subsequent processing steps.

[0042] The first conveyor belt 102, the second conveyor belt 103, the third conveyor belt 104 and the fourth conveyor belt 105 are all equipped with limiting wheels on both sides to adjust the width of the dough in time during transportation, so as to prevent the lateral length of the dough from exceeding the lateral length of the first conveyor belt 102, the second conveyor belt 103, the third conveyor belt 104 and the fourth conveyor belt 105, which would affect the processing and transportation and cause contamination of the food.

[0043] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. The scope of protection of this disclosure shall be determined by the scope of the claims.
