Description

Technical Field

[0001] The invention relates to food processing equipment, in particular to an automatic processing device for coarse grain steamed corn bread. Background Art

[0002] Wowotou is a common pasta in northern China. Coarse grain Wowotou is made of corn flour or other grain flour, and usually weighs two or three taels. Coarse grain Wowotou is small on the top and large on the bottom, hollow in the middle, in a cone shape. In order to make it easier to steam, there is a hole at the bottom. Today, Wowotou has become a green, delicious, nutritious and healthy delicacy. Coarse grains are very good for health, so they are widely loved by consumers, especially pure corn flour Wowotou, which has higher nutritional value and is more beneficial to health.

[0003] Steamed corn bread made of pure corn flour or pure corn flour and other grains (such as soybean flour, sweet potato flour, etc.) is generally made of a certain proportion of corn flour and water. If the water content is low, the corn flour will be loose and difficult to shape. A moderate proportion will make it easy to shape, but it is relatively sticky. This is why many steamed corn breads need to be mixed with other flours. Therefore, steamed corn bread made of pure corn flour (referring to steamed corn bread containing only corn flour and water) is difficult to process with pasta equipment such as steamed bread processing machines, and mainly relies on manual production, so the production efficiency is low. Moreover, manual production requires human intervention, and hands will inevitably come into contact with the steamed corn bread, which is not hygienic enough. Summary of the invention

[0004] In order to solve the above problems, the purpose of the present invention is to provide an automatic processing device for coarse grain steamed corn bread.

[0005] To achieve the above purpose, the technical solution of the present invention is: an automatic processing device for coarse grain steamed corn bread, which includes a stirring device, a material conveying device, a forming device, an XY-axis electric slide and a plate swinging table in sequence from feeding to forming, the stirring device, the material conveying device, and the forming device are supported on the frame in sequence from high to low, the plate swinging table is fixedly connected to one side of the frame, the XY-axis electric slide is installed on the frame above the plate swinging table, the upper mold part of the forming device is fixed on the lifting plate of the XY-axis electric slide, and the lower mold part of the forming device is installed at the discharge end of the material conveying device;

[0006] The stirring device comprises a horizontal stirring barrel and a stirring motor on one side of the stirring barrel, a stirring blade of a horizontal stirring shaft driven by the stirring motor is located in the stirring barrel, and a discharge end of the stirring barrel is located above a feeding port of the material conveying device;

[0007] The material conveying device comprises an extrusion feed box and a screw conveyor, wherein the feed end of the screw conveyor is connected to the bottom of the extrusion feed box, and the discharge end of the screw conveyor is connected to the feed end of the forming device;

[0008] The forming device includes a feeding box and a lower module rotatably supported on the top of the feeding box. The feeding end of the feeding box is communicated with the discharging end of the screw conveyor. The upper module is vertically fixed on one side of the lifting plate of the XY-axis electric slide table. The lower module is a cone, and the upper module is an inverted funnel shape. The upper module is buckled onto the lower module to form a forming cavity for filling materials between the upper module and the lower module. A blow pipe communicated with the forming cavity is arranged at the top of the upper module, and the lower end of the forming cavity is internally communicated with the upper end of the feeding box;

[0009] The plate placing table includes a box body with a box door and a horizontal stainless steel table top arranged on the top of the box body. The control buttons of the stirring device, the material conveying device, the forming device and the XY-axis electric slide table are located on the frame on one side of the XY-axis electric slide table.

[0010] Further, a stirring discharge port for controlling discharging is arranged at the discharging end of the stirring device, and a guide plate with the lower end fixedly connected to the edge of the extrusion feeding box is arranged below the stirring discharge port; a vertical propulsion cylinder is fixed in the top frame of the extrusion feeding box of the material conveying device, the lower end of the cylinder push rod of the propulsion cylinder is fixedly connected with a horizontal cover plate, a circle of food-grade silica gel ring is arranged on the lower surface of the cover plate, and the cover plate and the silica gel ring can just be inserted into the extrusion feeding box;

[0011] The material can be directly introduced into the extrusion feeding box through the guide plate without preventing the cover plate from moving up and down. The cover plate can move up and down driven by the propulsion cylinder. It can not only be used as a lid, but also play a role similar to piston propulsion, and can inject the material into the feeding box of the forming device with a certain pressure, cooperate with the screw conveyor to convey the material more effectively, and prevent empty material at the discharging part at the same time.

[0012] Further, the top opening of the feeding box of the forming device is covered with a sealing cover plate, a forming cavity feeding port is opened on the sealing cover plate, the bottom of the lower module is fixed on the vertical hollow rotating shaft of the lower module in the feeding box, the hollow rotating shaft of the lower module penetrates through the bottom of the feeding box, and the penetrating part is provided with a sealing ring for plugging. A hollow circular blade is also arranged at the bottom of the lower module, the circular blade is located below the forming cavity feeding port and closely adheres to the lower surface of the forming cavity feeding port, the lower module passes through the forming cavity feeding port, the diameter of the forming cavity feeding port is larger than the diameter of the lower module, and a hollow rotating shaft driving pulley connected with the motor is arranged at the lower end of the hollow rotating shaft of the lower module;

[0013] The rotation of the circular blade can be driven by driving the hollow rotating shaft driving pulley by the motor. When the material is filled and formed in the forming cavity, in order to separate the material in the forming cavity from the material in the feeding box and facilitate the subsequent discharge of the steamed bun formed in the forming cavity, the circular blade is a hollow structure, which can not only enable the material to enter the forming cavity through the hollow structure, but also cut the bottom of the steamed bun from the material in the feeding box, facilitating lifting after forming and discharging the steamed bun from the upper die.

[0014] Furthermore, a vertical and rotatable hollow shaft penetrates through the top of the upper module of the forming device. A conical spiral spring is fixedly connected to the lower end of the hollow shaft and is closely attached to the inner wall of the upper module. A silica gel conical mold cylinder is inserted into the cone formed by the conical spiral spring. The lower opening edge of the silica gel conical mold cylinder is fixed to the lower edge of the upper module, so that the forming cavity is covered by the silica gel conical mold cylinder. The conical spiral spring rotates on the outer surface of the silica gel conical mold cylinder along with the hollow shaft. A hollow shaft drive pulley connected to the motor is fixedly arranged on the outer periphery of the upper end of the hollow shaft. The blowpipe penetrates through the hollow shaft through a rotary joint and is internally communicated with the upper end of the upper mold cylinder.

[0015] Since the viscous paste formed by mixing coarse grain flour and water is relatively sticky, it is easy to cause the formed steamed buns to not fall out of the upper mold, affecting the processing efficiency. A conical spiral spring is provided. The conical spiral spring is located on the outer side wall of the silica gel conical mold cylinder. Because the steamed bun is formed in the forming cavity and the forming cavity is covered by the silica gel conical mold cylinder, a soft silica gel conical mold cylinder will cover the steamed bun. The conical spiral spring closely attached to the outer side wall of the silica gel conical mold cylinder will indirectly rotate spirally on the surface of the steamed bun under the drive of the motor, the hollow shaft drive pulley and the hollow shaft, forming a downward rotating force on the surface of the silica gel conical mold cylinder, and then indirectly transmitted to the steamed bun through the soft silica gel conical mold cylinder, finally separating the silica gel conical mold cylinder from the steamed bun inside it, effectively separating and dropping the steamed bun from the upper mold, and ensuring that each feeding can be separated and dropped, better guaranteeing the discharging efficiency and effectively avoiding empty feeding in the upper mold.

[0016] Furthermore, the rotating shaft of the spiral blade at the discharging end of the screw conveyor penetrates through the feeding port of the feeding box and is supported by a bearing on the other side inside the feeding box, effectively supporting the discharging end of the screw conveyor, thus ensuring the coaxiality of the rotation of the spiral blade of the screw conveyor and effectively avoiding the wear of the spiral blade of the screw conveyor.

[0017] Furthermore, the outer shell of the lower module is formed by coiling spiral stainless steel wires, and there are gaps between each layer of stainless steel wires of the outer shell of the lower module. The inside of the outer shell of the lower module is filled with silica gel. A metal water spray pipe penetrates through the hollow rotating shaft of the lower module. The lower end of the metal water spray pipe is fixed on the machine frame and is communicated with a water pump for external water supply. The upper end of the metal water spray pipe is communicated with a hollow disc. The hollow disc is fixed to the upper end of the outer shell of the lower module, and drain holes communicated with the inside of the internal hollow disc are evenly arranged on the peripheral side walls of the hollow disc.

[0018] After the steamed bun is formed in the forming cavity, the upper mold is lifted. Since the contact surface with the inner side of the upper mold is much larger than the outer side of the lower mold located in the upper mold, the adhesion force of the upper mold to the steamed bun is greater, making it easier for the formed steamed bun to separate from the lower mold first, facilitating the discharge and arranging of the steamed bun on the plate. To avoid the situation where the steamed bun may remain on the lower mold, external water, such as the water supplied by a water pump, can be sprayed onto the internal silica gel cone through a metal water spray pipe and then seep out of the lower module housing through the silica gel cone, making the surface of the lower module housing wet and making it easier for the formed steamed bun to separate from the lower mold first.

[0019] Further, to facilitate the replacement of the upper module, a horizontal upper module fixing plate integrated with the upper module is provided on one side wall of the top of the upper module, and a mounting hole for fixedly connecting with the lifting plate is opened on the upper module fixing plate.

[0020] Further, to moisten the upper module and avoid the residue of internal materials, a moistening nozzle bent upward is provided on one side of the bottom of the feeding box.

[0021] Further, to ensure the feeding efficiency and the cutting effect, a water spray pipe through hole for passing through the metal water spray pipe is opened in the center of the circular blade. Multiple spiral long through holes are opened on the surface of the circular blade centered on the water spray pipe through hole, so that the feeding port of the forming cavity is communicated with the inside of the feeding box through each spiral long through hole. The spiral long through holes are longer and have a relatively larger area, which is beneficial for the material to pass through. The blade side walls between the spiral long through holes form spiral cutters, and the cutting is more thorough. A pipe joint is provided on one side of the feeding box, and the pipe joint is communicated with an external air pressure regulating device through a hose.

[0022] The present invention provides an automatic processing device for steamed buns with a high degree of automation, which can realize the automatic processing of steamed buns without manual intervention, is cleaner and more hygienic, has high efficiency, can effectively avoid the adhesion of corn batter to the upper and lower modules, has a good forming effect, and is not easily damaged after forming.

[0029] The following is a detailed description of this embodiment in conjunction with the accompanying drawings:

[0030] This embodiment provides an automatic processing device for coarse grain steamed buns. Please refer to the accompanying drawings in the specification Figures 1-4 .

[0031] As Figures 1-4 shown, the automatic processing device for steamed buns includes, in sequence from feeding to forming, a stirring device, a material conveying device, a forming device, an XY-axis electric slide table (such as the xy-axis synchronous belt-driven precision electric slide table linear module produced by Dongguan Keyang Automation Equipment Co., Ltd.), and a plate placing table. The stirring device, the material conveying device, and the forming device are supported on the frame 1 in sequence from high to low. The plate placing table is fixedly connected to one side of the frame 1. The XY-axis electric slide table is installed on the frame 1 above the plate placing table. The upper die part of the forming device is fixed on the lifting plate 9 of the XY-axis electric slide table, and the lower die part of the forming device is installed at the discharge end of the material conveying device;

[0032] The stirring device includes a horizontal stirring barrel 2 and a stirring motor 3 on one side of the stirring barrel 2. The horizontal stirring shaft stirring blades driven by the stirring motor 3 are located inside the stirring barrel 2. The discharge end of the stirring barrel 2 is located above the feed inlet of the material conveying device;

[0033] The material conveying device includes an extrusion feeding box 4 and a screw conveyor 5. The feeding end of the screw conveyor 5 is communicated with the bottom of the extrusion feeding box 4. A stirring discharge port 15 for controlling the discharge is arranged at the discharge end of the stirring device. A material guiding plate 16 is arranged below the stirring discharge port 15, and the lower end of the material guiding plate 16 is fixedly connected with the edge of the extrusion feeding box 4. A vertical propulsion cylinder 17 is fixed in the top frame 1 of the extrusion feeding box 4 of the material conveying device. The lower end of the cylinder push rod of the propulsion cylinder 17 is fixedly connected with a horizontal cover plate 18. A food-grade silica gel ring 19 is arranged on the lower surface of the cover plate 18. The cover plate 18 and the silica gel ring 19 can just be inserted into the extrusion feeding box 4.

[0034] The forming device includes a feeding box 6 and a lower module 7 rotatably supported on the top of the feeding box 6. One side of the bottom of the feeding box 6 is provided with a wet spray head 34 bent upward. The rotating shaft of the spiral blade at the discharge end of the screw conveyor 5 penetrates through the feeding port of the feeding box 6 and is supported by bearings on the other side inside the feeding box 6. The feeding end of the feeding box 6 is communicated with the discharge end of the screw conveyor 5. The upper module 8 is vertically fixed on one side of the lifting plate 9 of the XY-axis electric slide table. The lower module 7 is a cone, and the upper module 8 is an inverted funnel shape. And on one side wall of the top of the upper module 8, there is a horizontal upper module fixing plate 32 integrated with the upper module 8. Installation holes for fixedly connecting with the lifting plate 9 are opened on the upper module fixing plate 32. When the upper module 8 is buckled onto the lower module 7, a forming cavity 10 for filling materials is formed between the upper module 8 and the lower module 7. A blowing pipe 11 communicated with the forming cavity 10 is arranged on the top of the upper module 8. The blowing pipe 11 is communicated with the outside and is connected with an air pump for blowing air into the forming cavity 10. The lower end of the forming cavity 10 is communicated with the inside of the upper end of the feeding box 6. The top opening of the feeding box 6 of the forming device is covered with a sealing cover plate 20. A forming cavity feeding port 21 is opened on the sealing cover plate 20. The bottom of the lower module 7 is fixed on a vertical lower module hollow rotating shaft 22 inside the feeding box 6. The lower module hollow rotating shaft 22 penetrates through the bottom of the feeding box 6, and the penetrating part is provided with a sealing ring for plugging. A circular blade 23 is also arranged at the bottom of the lower module 7. A water spray pipe perforation 36 for passing through the metal water spray pipe 31 is opened at the center of the circular blade 23. Multiple spiral long through holes 37 are opened on the surface of the circular blade 23 with the water spray pipe perforation 36 as the center, so that the forming cavity feeding port 21 is communicated with the inside of the feeding box 6 through each spiral long through hole 37. The spiral long through holes 37 are similar to the shape of fan blades and are arranged around the axis center of the water spray pipe perforation 36, so that the spiral long through holes 37 are large enough to ensure the feeding effect and uniformity. The blades of the circular blade 23 are formed between adjacent spiral long through holes 37. When the circular blade 23 rotates, the materials can be cut and separated by the blades. The circular blade 23 is located below the forming cavity feeding port 21 and is closely attached to the lower surface of the forming cavity feeding port 21. The lower module 7 passes through the forming cavity feeding port 21. The diameter of the forming cavity feeding port 21 is larger than the diameter of the lower module 7. A hollow rotating shaft driving pulley 35 connected with the motor is arranged at the lower end of the lower module hollow rotating shaft 22;

[0035] One side of the feeding box 6 is provided with a pipe joint 38. The pipe joint 38 is connected to an external air pressure regulating device through a hose. The air pressure regulating device can inhale and add gas. For example, when injecting and forming, gas is added to make the air pressure in the feeding box 6 relatively high. Under the action of high air pressure, it is more conducive to the extrusion of the material in the feeding box 6 into the forming cavity 10, and the material filling is more uniform. When demolding, that is, when the steamed bun is discharged from the forming cavity 10 after forming, at this time, inhalation is carried out, or gas addition is closed, and the air pressure in the feeding box 6 drops rapidly. During the process of air pressure reduction, a back-drawing effect is formed, which is more conducive to absorbing the residual pressure after injection in the feeding box 6 and facilitating the separation of the upper and lower molds, that is, more facilitating discharging and blanking;

[0036] A vertical and rotatable hollow shaft 24 penetrates through the top of the upper module 8 of the forming device. A bearing 33 is sleeved on the part of the hollow shaft 24 located in the cylinder at the top of the upper module 8. The lower end of the hollow shaft 24 is fixedly connected with a conical spiral spring 25 closely attached to the inner side wall of the upper module 8. A silica gel conical mold tube 26 is inserted into the cone formed by the conical spiral spring 25. The lower opening edge of the silica gel conical mold tube 26 is fixed on the lower edge of the upper module 8, so that the forming cavity 10 is covered with the silica gel conical mold tube 26 outside, and the conical spiral spring 25 rotates on the outer surface of the silica gel conical mold tube 26 along with the hollow shaft 24. A hollow shaft driving pulley 27 connected to the motor is fixedly arranged on the outer periphery of the upper end of the hollow shaft 24. The blowing pipe 11 penetrates through the hollow shaft 24 through a rotary joint 28 and is internally communicated with the upper end of the upper mold tube 26;

[0037] The lower module housing 29 of the lower module 7 is formed by coiling spiral stainless steel wires. The conical spiral spring 25 can also be formed by coiling spiral stainless steel wires. The gap of the conical spiral spring 25 is relatively larger, and the diameter of the stainless steel wire is about 2.5 mm. There are gaps between each layer of stainless steel wires of the lower module housing 29. The inside of the lower module housing 29 is filled with a silica gel body 30. A metal water spray pipe 31 penetrates through the lower module hollow rotating shaft 22. The lower end of the metal water spray pipe 31 is fixed on the frame 1 and is communicated with a water pump for external water supply. The upper end of the metal water spray pipe 31 is communicated with a hollow disc 39. The hollow disc 39 is fixed at the upper end of the lower module housing 29, and drain holes 40 communicated with the inside of the internal hollow disc 39 are uniformly arranged on the peripheral side walls of the hollow disc 39. After injecting materials into the forming cavity 10 or after forming and demolding, the water pump discharges water through the metal water spray pipe 31, the hollow disc 39, and the drain holes 40. The water uniformly flows out from the top of the lower module housing 29, uniformly wetting the outer surface of the lower module housing 29, playing a good lubricating and flushing role. Wetting and lubricating can help the separation of the lower module housing 29 from the steamed bun. In order to facilitate the control of the pressure during the injection of the upper and lower molds, a pressure sensor for detecting the internal pressure of the upper module can be arranged on the side wall of the upper module;

[0038] The plate-setting table comprises a box body 13 with a box door 12 and a stainless steel table top 14 arranged horizontally on the top of the box body 13. The control buttons of the stirring device, the material conveying device, the forming device and the XY-axis electric slide are located on the frame 1 on one side of the XY-axis electric slide.

[0039] The working principle of the present invention is as follows: coarse grain flour and water with a general weight ratio of 10:7 are poured into the mixing barrel 2, the mixing motor 3 is started to drive the internal mixing blades to rotate, and the mixing is performed for 5-30 minutes. After the mixing is completed, the mixing outlet 15 is opened, and the formed coarse grain paste is discharged into the material conveying device including the extrusion feeding box 4. The screw conveyor 5 works to deliver the coarse grain paste to the forming device including the feed box 6, and fills the feed box 6. During the forming, the XY-axis electric slide first drives the lifting plate 9 to work, so that the upper module 8 is buckled on the lower module 7, such as Figure 3, the screw conveyor 5 continues to convey forward and applies a squeezing force to the feeding box 6, causing the material in the feeding box 6 to form a squeezing force that forces it upward into the forming cavity 10. At the same time, since the lower end of the silicone conical die barrel 26 is sleeved on the edge of the upper die block 8, the bottom edge of the upper die block 8 is equivalent to a seal, and the bottom edge of the silicone conical die barrel 26 closely adheres to the sealing cover plate 20 to also form a seal. The blow pipe 11 is connected to the outside. Therefore, the silicone conical die barrel 26 at the top of the upper die block 8 is connected to the outside through the blow pipe 11. At this time, under the conveying and squeezing action of the screw conveyor 5, the material is squeezed into the forming cavity 10, and the original air in the forming cavity 10 is discharged to the outside through the blow pipe 11, facilitating the squeezing of the material into the forming cavity 10 for forming, so that the coarse grain batter in the feeding box 6 is fully and quickly filled into the forming cavity 10. The screw conveyor 5 stops working. At this time, the motor drives the hollow rotating shaft to drive the belt pulley 35 to rotate, thereby driving the hollow rotating shaft 22 of the lower die block, the circular blade 23, and the lower die block 7 to rotate. This not only separates the formed steamed bun from the lower die block 7, but also the lower die block 7 has an upward spiral thrust, making it easier to separate. Moreover, the circular blade 23 rotates to cut off the connection part between the steamed bun and the feeding box 6. Then, the XY-axis electric slide table first drives the lifting plate 9 to work and lift the upper die block 8. Since the viscous coarse grain batter formed by mixing coarse grains and water is relatively large, the formed steamed bun remains in the upper die. To ensure that the steamed bun does not fall out during movement, at this time, the blow pipe 11 can also perform a certain amount of suction with a relatively low suction force to maintain a certain negative pressure in the forming cavity 10, as long as it can prevent the steamed bun from falling out. The steamed bun follows the upper die block 8 to the stainless steel tabletop 14. When discharging the steamed bun, the motor drives the hollow shaft to drive the belt pulley 27 to rotate, so that the conical spiral spring 25 closely attached to the outer wall of the silicone conical die barrel 26 rotates spirally on the surface of the steamed bun indirectly. A downward rotating force is formed on the surface of the steamed bun through the conical spiral spring 25 on the surface of the silicone conical die barrel 26, and is indirectly transmitted to the steamed bun through the soft silicone conical die barrel 26. At the same time, the rotation of the conical spiral spring 25 also forms a softening effect on the surface of the steamed bun, making the surface of the steamed bun flat and smooth, more beautiful. In addition, the air pump blows air into the forming cavity 10 through the blow pipe 11, which also forms a force to push the steamed bun outward. Finally, the silicone conical die barrel 26 is separated from the steamed bun inside it, completing the forming process of the steamed bun. The discharged steamed buns can be automatically arranged in rows on the steaming tray of the stainless steel tabletop 14 by controlling the XY-axis electric slide table, and then can be cooked using equipment such as a steamer or a steaming box for loading and transporting.

[0040] It should be noted that the forming device can be 2 groups, 4 groups, 6 groups, etc., multiples of 2. In addition, the stirring device, the screw conveyor 5, the XY-axis electric slide table, the cylinder, and the vacuum pump are all commonly used component devices in the food industry, and will not be elaborated here.

[0041] Certainly, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
