Description

Technical Field

[0001] This utility model relates to the field of vermicelli production equipment, specifically to a pulping machine for sweet potato vermicelli production. Background Technology

[0002] Sweet potato vermicelli is a food with a long history in my country, dating back to the late Ming and early Qing dynasties. With the advancement of technology, sweet potato vermicelli has gradually upgraded from manual production to industrialized production. The production process includes core steps such as raw material processing, starch extraction, starch preparation and dough mixing, slurry spreading and shaping, maturation and cooling, drying and packaging. In the slurry spreading and shaping stage, the uniformity of the slurry's coarseness determines the quality of the sweet potato vermicelli. Maintaining consistent pressure during the spreading process can achieve uniform slurry coarseness. However, existing piston-type slurry spreading machines are prone to slurry backflow during the spreading process. Therefore, it is necessary to design a slurry spreading machine for sweet potato vermicelli production that prevents the slurry that has been squeezed out of the pressing cylinder from being sucked back. Summary of the Invention

[0003] The purpose of this utility model is to provide a pulping machine for producing sweet potato vermicelli, which has the advantage of preventing the pulp that has been squeezed out of the pressing cylinder from being sucked back.

[0004] The technical solution adopted is as follows:

[0011] Compared to existing technologies, the advantages are:

[0012] 1. This utility model utilizes a reciprocating moving mechanism to drive the pressing cylinder to move vertically back and forth. During the lifting process of the pressing cylinder, the electric valve is controlled to open, so that the air pressure on both sides of the pressing cylinder is balanced, thus preventing the slurry that has been squeezed out from the spreading cylinder from being sucked back by the pressing cylinder during the lifting process.

[0013] 2.

[0018] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:

[0019] Example 1: A slurry spreading machine for producing sweet potato vermicelli includes a slurry spreading cylinder 1, with both ends of the upper end of the slurry spreading cylinder 1 open, and a perforated plate 2 installed at the lower end of the slurry spreading cylinder 1. The perforated plate 2 is detachably connected to the lower end of the slurry spreading cylinder 1, and different perforated plates 2 with different apertures can be replaced according to different production needs to produce sweet potato vermicelli of different thicknesses.

[0020] A conveying pipe 3 is provided in the middle of the slurry cylinder 1. The conveying pipe 3 is connected to a hopper, which is filled with slurry. The conveying pipe 3 is used to convey slurry into the slurry cylinder 1. A pressing cylinder 5 is vertically slidably installed inside the slurry cylinder 1. The pressing cylinder 5 is a cylindrical shape with an open top and a closed bottom. A reciprocating moving mechanism connected to the pressing cylinder 5 is provided at the upper end of the slurry cylinder 1. The reciprocating moving mechanism controls the pressing cylinder 5 to move vertically back and forth inside the slurry cylinder 1. When the pressing cylinder 5 moves downward, it presses down the slurry in the slurry cylinder 1 and squeezes it out from each mesh to form sweet potato noodles. After the pressing cylinder 5 rises above the height of the conveying pipe, the slurry in the hopper enters the slurry cylinder 1 from the conveying pipe 3.

[0021] During the movement of the pressing cylinder 5, the upper end face of the pressing cylinder 5 is always higher than the upper end face of the conveying pipe 3 to prevent the slurry from entering the slurry distribution cylinder 1 from the upper end of the pressing cylinder 5. A balance pipe 10 is provided on the lower end face of the inside of the pressing cylinder 5. An electric valve 11 is installed on the balance pipe 10. The electric valve 11 is connected to a power supply line 13. The power supply line 13 extends to the top of the slurry distribution cylinder 1 and connects the power supply 13 and the controller 14. During the lifting process of the pressing cylinder 5, the controller 14 controls the electric valve 11 to open, so that the air pressure on both sides of the pressing cylinder 5 is balanced, and to prevent the slurry that has been squeezed out from the slurry distribution cylinder 1 during the rising process of the pressing cylinder 5 from being sucked back by the pressing cylinder 5.

[0022] Example 2: A slurry spreading machine for producing sweet potato vermicelli includes a slurry spreading cylinder 1, with both ends of the upper end of the slurry spreading cylinder 1 open, and a perforated plate 2 installed at the lower end of the slurry spreading cylinder 1. The perforated plate 2 is detachably connected to the lower end of the slurry spreading cylinder 1, and different perforated plates 2 with different apertures can be replaced according to different production needs to produce sweet potato vermicelli of different thicknesses.

[0023] A conveying pipe 3 is provided in the middle of the slurry cylinder 1. The conveying pipe 3 is connected to a hopper, which is filled with slurry. The conveying pipe 3 is used to convey slurry into the slurry cylinder 1. A pusher screw 4 is rotatably installed inside the conveying pipe 3. A rotating motor connected to the pusher screw 4 is installed at the end of the conveying pipe 3. A pressure cylinder 5 is vertically slidably installed inside the slurry cylinder 1. The pressure cylinder 5 is a cylindrical shape with an open top and a closed bottom. Multiple annular grooves are opened on the outside of the pressure cylinder 5. Sealing rings are installed in each annular groove. A reciprocating moving mechanism connected to the pressure cylinder 5 is provided at the upper end of the slurry cylinder 1.

[0024] The reciprocating movement mechanism includes a crankshaft 6, which is rotatably positioned above the slurry cylinder 1. The crankshaft 6 is connected to a drive mechanism and a connecting rod 9, the lower end of which is hinged to the upper end of the pressure cylinder 5. The drive mechanism includes a reducer 7 and a variable frequency motor 8. The reducer 7 includes an input shaft and an output shaft. The input shaft is connected to the variable frequency motor 8, and the output shaft is connected to the crankshaft 6. The rotation of the drive mechanism is controlled by frequency conversion.

[0025] The reciprocating movement mechanism controls the pressing cylinder 5 to move vertically back and forth inside the slurry cylinder 1. When the pressing cylinder 5 moves downward, it presses down the slurry in the slurry cylinder 1 and squeezes it out from each mesh to form sweet potato noodles. After the pressing cylinder 5 rises above the height of the conveying cylinder, the slurry in the hopper enters the slurry cylinder 1 from the conveying pipe 3.

[0026] During the movement trajectory of the pressure cylinder 5, the upper end face of the pressure cylinder 5 is always higher than the upper end face of the conveying pipe 3 to prevent the slurry from entering the slurry distribution cylinder 1 from the upper end of the pressure cylinder 5. A balance pipe 10 is provided on the lower end face of the inside of the pressure cylinder 5. An electric valve 11 is installed on the balance pipe 10. The electric valve 11 is connected to a power supply line 13. The power supply line 13 extends to the top of the slurry distribution cylinder 1 and connects the power supply 13 and the controller 14. A height sensor 12 is provided on the slurry distribution cylinder. The height sensor 12 is connected to the power supply 13 and the controller 14. The controller 14 is connected to the drive motor.

[0027] The working principle is as follows:

[0028] The slurry is placed in the hopper, and the reciprocating moving mechanism is started. The drive mechanism controls the crankshaft 6 to rotate, thereby controlling the vertical reciprocating movement of the pressing cylinder 5. During the descent of the pressing cylinder 5, the slurry inside the spreading cylinder 1 is extruded from the mesh plate 2 to form powder strips. During the descent of the pressing cylinder 5, the controller 14 controls the electric valve 11 to open, so that the air pressure on both sides of the pressing cylinder 5 is balanced, and the slurry that has been extruded from the spreading cylinder 1 during the descent of the pressing cylinder 5 is not sucked back by the pressing cylinder 5. When the pressing cylinder 5 is higher than the conveying pipe 3, the height sensor 12 sends a signal, and the controller 14 controls the rotating motor to rotate. The pushing screw 4 pushes the slurry into the spreading cylinder 1 to complete the feeding. As the pressing cylinder 5 descends, the rotating motor stops rotating, the feeding is completed, and the next cycle of spreading begins.
