Description

Technical Field

[0001] The utility model relates to the technical field of sweet potato starch processing, in particular to a double-helix vacuum dough kneading machine. Background Art

[0002] Vermicelli is a traditional food made from sweet potatoes and potatoes, which is processed into a dry strip. Each part of China has its own unique production process. The finished vermicelli is off-white, yellow or brown. It can be divided into round vermicelli, thin vermicelli and wide vermicelli according to its shape. After cooking, the vermicelli tastes smooth and elastic. It can be made into delicious food with vegetables, pork, chicken, etc.

[0003] Vermicelli needs to be processed and formed with sweet potato starch, and a vacuum dough kneading machine is needed to process the sweet potato starch into dough. The dough processed by the vacuum dough kneading machine is soft in texture, without bubbles inside the dough, and has excellent molding effect. However, the vacuum dough kneading machine is difficult to open after vacuuming, and it is more difficult for workers to open the end cover. At the same time, there are many types of vacuum dough kneading machines, such as single spiral and double spiral. The double spiral type has higher processing efficiency, but the gap between the two spiral shafts and the bottom wall of the dough barrel is large, and the dough located here is difficult to process well. For this reason, we propose a double spiral vacuum dough kneading machine. Utility Model Content

[0016] 1. The worker controls the external oil pump to supply oil to the hydraulic cylinder through the single-chip computer. The telescopic end of the hydraulic cylinder extends, pushing the lower end of the connecting rod to move upward, and the upper end of the connecting rod moves upward, pushing the sliding column to slide upward inside the slide. Due to the limitation of the slide, the upper end of the connecting rod can only move upward at this time, and the flip seat moves upward. When the sliding column at the upper end touches the top of the vertical slide of the slide, the end cover has left the upper end of the dough barrel. The telescopic end of the hydraulic cylinder continues to extend, and the sliding column at the lower end enters the arc-shaped slide of the slide. The spacing between the top of the vertical slide and the top of the arc-shaped slide is the same as the spacing between the vertically adjacent sliding columns, so that when the telescopic end of the hydraulic cylinder is retracted, the sliding column at the lower end slides first to avoid the end cover from being unable to buckle, and the sliding column at the lower end slides upward clockwise, causing the sliding column at the upper end to rotate clockwise at the top of the vertical slide of the slide, and the flip seat rotates clockwise with the central axis of the sliding column at the upper end as the center of the circle, and the end cover rotates clockwise and flips synchronously, thereby realizing the opening of the end cover without manual opening and support, which is convenient for the workers' subsequent work.

[0017] 2. The worker pours the sweet potato starch into the dough barrel, adds appropriate amount of water, and then turns on the motor. The output shaft of the motor drives the spiral dough shaft and pulley 2 on the front side to rotate. Pulley 2 drives pulley 1 and the spiral dough shaft on the rear side through the belt to rotate, thereby kneading the sweet potato starch. The double-sided arc plate greatly reduces the gap between the two spiral dough shafts and the dough barrel, preventing the sweet potato starch from being stirred by the spiral dough shafts in this gap, so that the quality of the dough after the sweet potato starch is formed is better.
