Technical Field
[0001] The utility model relates to the technical field of food processing equipment, in particular to a gas control extrusion mechanism in the production process of puffed food. Background Technique
[0002] Extrusion puffed food is a process in which materials are pushed forward by the driving force of a screw in an extruder, and the materials are subjected to mixing, stirring, friction and high shear force to obtain and accumulate energy to reach high temperature and high pressure, and the materials are puffed. It is widely used in the production of puffed food.
[0003] Most of the current extrusion equipment for puffed food production is similar in overall structure. The proportioned raw materials are extruded by a screw. The high temperature and high pressure generated by the strong stirring, mixing and shearing of the raw materials between the screw and the sleeve, and the raw materials are in a molten state in the extrusion cavity. As the raw materials are discharged from the outlet, the raw materials expand due to the pressure difference inside and outside. There are some functional deficiencies in the actual use process, and there is room for improvement. For example, it completely relies on the pressure difference to make the raw materials fluffy. When the diameter of the discharged raw materials is large, the inner core of the raw materials is still agglomerated, only the outside is fluffy, and the taste is not good when eaten. It cannot expand and loosen synchronously from the inside to the outside, and does not have the function of controlling gas and pressurizing to promote puffing.

[0007] The pressurizing assembly includes two groups of square sockets, which are respectively arranged on the left sides of the front and rear ends of the extrusion barrel. A variety of air inlets are arranged at one end of the square socket near the extrusion barrel. An air pump is installed at the bottom end inside the bottom box body. A distribution housing is inserted into the square socket. A distribution cavity is arranged at one end of the distribution housing far from the extrusion barrel. A variety of inclined air outlets are arranged at one end of the distribution housing near the extrusion barrel. A solenoid valve is installed on the right side of the distribution housing. A Y-shaped air pipe is movably connected between the air pump and the solenoid valve. Fixing plates are respectively welded to the upper and lower ends of the distribution housing, and two fixing screws are inserted into the fixing plates.
[0008] Preferably, the air pump, the Y-shaped air pipe, the solenoid valve, the distribution cavity, the inclined air outlets, and the inside of the extrusion barrel are connected in communication. The shape and size of the outside of the distribution housing are adapted to the shape and size of the inside of the square socket.

A sliding adjustment plate is arranged outside the adjusting slide rods. A discharge guiding plate is welded to the left side of the sliding adjustment plate. Steel sliding sleeves are respectively fixedly connected to the inside of the four corners at the top end of the sliding adjustment plate. Positioning handwheels are respectively inserted into the two sides of the front and rear ends of the sliding adjustment plate. A plurality of positioning screw holes are arranged inside the adjusting slide rods.
[0014] Preferably, the inner diameter of the steel sliding sleeve is adapted to the outer diameter of the adjusting slide rod, and the steel sliding sleeve can slide up and down along the outside of the adjusting slide rod.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The air control extrusion mechanism in the production process of the puffed food not only realizes the function of air control and pressurization to promote puffing, but also realizes the function of accelerating the feeding and preventing caking, and also realizes the function of facilitating the adjustment of the height of the guiding plate.
[0016] (1) By setting an air pump, a Y-shaped air pipe, a distribution housing, a solenoid valve, a distribution chamber, an inclined air outlet channel, a fixing plate, fixing screws, a square socket and an air inlet hole, during use, the proportioned raw materials are poured into the hopper, and the raw materials in the hopper fall into the extrusion tube.

The solenoid valve can control the air intake volume through programming. The gas in the distribution chamber enters the extrusion tube through the inclined air outlet channel and the air inlet hole, and mixes with the extruded raw materials, making the raw materials contain gas inside. As the raw materials are extruded, the pressure difference between the inside and outside of the raw materials is large, and the internal gas quickly escapes outward, and the whole dough piece will be in a loose state from the inside to the outside. The square socket facilitates the insertion of the distribution housing and is fixedly connected through the fixing plate and fixing screws, realizing the function of controlling air and pressurizing to promote puffing;
[0017] (2) By setting a fixed steel shell, a servo motor, a flexible shaft and a rubber ball, during use, the proportioned raw materials are poured into the hopper, and the raw materials in the hopper fall into the extrusion tube. During the falling process of the raw materials, the servo motor at the bottom of the fixed steel shell is turned on, and the servo motor drives the flexible shaft to swing at high speed. The rubber ball at the end of the flexible shaft hits the fixed steel shell at high speed, causing the fixed steel shell to generate high-frequency vibration, accelerating the falling of the raw materials and preventing them from caking and clogging, realizing the function of accelerating the feeding and preventing caking;
[0018] (3) By setting an adjusting slide bar, positioning screw holes, a sliding adjusting plate, a discharge guiding plate, a positioning handwheel and a steel sliding sleeve, during use, according to the size specification of the extruded raw material dough piece, the height of the discharge guiding plate can be adjusted. After loosening the four positioning handwheels, the sliding adjusting plate can be held and adjusted up and down along the adjusting slide bar. After adjusting to the appropriate height, the positioning handwheels are tightened again, and the positioning handwheels are clamped into the positioning screw holes, and the height of the sliding adjusting plate is fixed.

[0026] Embodiment 1: Please refer to Figures 1-5 , a gas control extrusion mechanism during the production of puffed food, including a bottom box body 1, a first support frame 12 is fixedly connected to the right side of the top of the bottom box body 1, a second support frame 22 is fixedly connected to the left side of the top of the bottom box body 1, an upper fixed frame 21 is arranged above the second support frame 22, the bottom end of the upper fixed frame 21 is horizontally fixedly connected with an extrusion barrel 13, a spiral extrusion roller 14 is horizontally movably connected to the right side inside the extrusion barrel 13, a reduction motor 15 is installed on the right side of the extrusion barrel 13, the top end of the extrusion barrel 13 is fixedly connected with a hopper 16, and a pressurization assembly capable of adding and controlling gas during the extrusion process is arranged outside the extrusion barrel 13;
[0027] Please refer to Figures 1-5, An air control extrusion mechanism in the production process of puffed food further includes a pressurizing component. The pressurizing component includes two square sockets 10, which are respectively arranged on the left side of the front and rear ends of the extrusion cylinder tube 13. At one end of the square socket 10 near the extrusion cylinder tube 13, there are multiple air inlets 11. At the bottom end inside the bottom box 1, an air pump 2 is installed. A distribution housing 4 is inserted into the square socket 10. At one end of the distribution housing 4 far from the extrusion cylinder tube 13, there is a distribution chamber 6. At one end of the distribution housing 4 near the extrusion cylinder tube 13, there are multiple oblique air outlets 7. A solenoid valve 5 is installed on the right side of the distribution housing 4. An Y-shaped air pipe 3 is movably connected between the air pump 2 and the solenoid valve 5. Fixing plates 8 are respectively welded to the upper and lower ends of the distribution housing 4, and two fixing screws 9 are inserted into the fixing plates 8;
[0028] The air pump 2, the Y-shaped air pipe 3, the solenoid valve 5, the distribution chamber 6, the oblique air outlets 7 are connected to the inside of the extrusion cylinder tube 13. The external shape and size of the distribution housing 4 are adapted to the internal shape and size of the square socket 10. The position and size of the oblique air outlets 7 and the air inlets 11 correspond one by one, and the oblique air outlets 7 and the air inlets 11 are arranged at equal intervals. One end of the fixing plate 8 near the extrusion cylinder tube 13 is in close contact with the extrusion cylinder tube 13. The fixing screw 9 passes through the fixing plate 8 and extends into the inside of the extrusion cylinder tube 13, which can add and control air during the extrusion process, making the puffed food loose from the inside out and the taste more crispy;
[0029] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, the air pump 2 continuously pumps air into the distribution housing 4 through the Y-shaped air pipe 3. The gas enters the distribution chamber 6 through the solenoid valve 5. The solenoid valve 5 can control the air intake volume through programming. The gas in the distribution chamber 6 enters the extrusion cylinder tube 13 through the oblique air outlets 7 and the air inlets 11 and is mixed with the extruded raw materials, making the raw materials contain gas inside. As the raw materials are extruded, the pressure difference between the inside and outside of the raw materials is large, and the internal gas quickly escapes outward. The whole dough will be in a loose state from the inside out. The square socket 10 facilitates the insertion of the distribution housing 4 and is fixedly connected through the fixing plate 8 and the fixing screw 9.
[0030] Embodiment 2: Fixed steel shells 17 are respectively welded to the left and right sides of the hopper 16. A servo motor 18 is installed at the bottom end of the fixed steel shell 17. A flexible shaft 19 is movably connected to the bottom end inside the fixed steel shell 17. A rubber ball 20 is arranged at the top end of the flexible shaft 19. The top end of the servo motor 18 is connected to the bottom end of the flexible shaft 19. The top end of the fixed steel shell 17 extends into the hopper 16 to accelerate the falling of the raw materials and prevent caking and blockage;
[0031] Specifically, as Figure 1 and Figure 2As shown in the figure, the servo motor 18 drives the flexible shaft 19 to swing at a high speed. The rubber ball 20 at the end of the flexible shaft 19 strikes the fixed steel shell 17 at a high speed, causing the fixed steel shell 17 to generate high-frequency vibrations and accelerating the falling of the raw materials.
[0032] Embodiment 3: Adjusting slide rods 23 are vertically and fixedly connected between the four corners at the top end of the second support frame 22 and the four corners at the bottom end of the upper fixing frame 21 respectively. A sliding adjustment plate 25 is arranged outside the adjusting slide rods 23. A discharge guiding plate 26 is welded to the left side of the sliding adjustment plate 25. Steel sliding sleeves 28 are fixedly connected to the inside of the four corners at the top end of the sliding adjustment plate 25 respectively. Positioning handwheels 27 are inserted into the two sides of the front and rear ends of the sliding adjustment plate 25 respectively. Multiple groups of positioning screw holes 24 are arranged inside the adjusting slide rods 23. The inner diameter of the steel sliding sleeve 28 is adapted to the outer diameter of the adjusting slide rod 23. The steel sliding sleeve 28 can slide up and down along the outside of the adjusting slide rod 23, facilitating the adjustment of the height of the guiding plate.
[0033] Specifically, as Figure 3 and Figure 5 shown in the figure, after loosening the four positioning handwheels 27, the sliding adjustment plate 25 can be supported to move up and down along the adjusting slide rod 23. After adjusting to the appropriate height, the positioning handwheels 27 are tightened again. The positioning handwheels 27 are snapped into the positioning screw holes 24, and the height of the sliding adjustment plate 25 is fixed. The steel sliding sleeve 28 and the adjusting slide rod 23 cooperate, and the up and down displacement of the sliding adjustment plate 25 is smooth and stable.
[0034] Working principle: When the utility model is in use, first, the proportioned raw materials are poured into the hopper 16. The raw materials in the hopper 16 fall into the extrusion cylinder tube 13. During the falling process of the raw materials, the servo motor 18 at the bottom of the fixed steel shell 17 is started. The servo motor 18 drives the flexible shaft 19 to swing at a high speed. The rubber ball 20 at the end of the flexible shaft 19 strikes the fixed steel shell 17 at a high speed, causing the fixed steel shell 17 to generate high-frequency vibration, accelerating the falling of the raw materials, preventing them from caking and clogging. The reduction motor 15 drives the spiral extrusion roller 14 to rotate continuously, pushing the raw materials to the left. Since the size of the discharge port is small, the raw materials will be gradually extruded and pressurized. During the extrusion process, the air pump 2 continuously pumps air into the distribution housing 4 through the Y-shaped air delivery pipe 3. The gas enters the distribution cavity 6 through the solenoid valve 5. The solenoid valve 5 can control the intake air volume through programming. The gas in the distribution cavity 6 enters the extrusion cylinder tube 13 through the inclined air outlet channel 7 and the air intake holes 11, and is mixed with the extruded raw materials, making the raw materials contain gas inside. As the raw materials are extruded, the pressure difference between the inside and outside of the raw materials is large, and the internal gas quickly escapes outward. The whole dough piece will present a loose state from the inside to the outside. The square socket 10 facilitates the insertion of the distribution housing 4, and is fixedly connected through the fixing plate 8 and the fixing screws 9. According to the size specifications of the extruded raw material dough pieces, the height of the discharge guiding plate 26 can be adjusted. After loosening the four positioning handwheels 27, the sliding adjustment plate 25 can be supported to move up and down along the adjustment slide rod 23. After adjusting to the appropriate height, the positioning handwheels 27 are tightened again. The positioning handwheels 27 are engaged with the positioning screw holes 24, and the height of the sliding adjustment plate 25 is fixed. The steel sliding sleeve 28 cooperates with the adjustment slide rod 23, and the sliding adjustment plate 25 moves up and down smoothly and stably.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
