Abstract
Description
Technical Field
[0001] This invention relates to the field of pastry production, and more particularly to an integrated device for mixing and drying premixed pastry powder. Background Technology
[0002] In the pastry making industry, premixed pastry powders are widely welcomed due to their ease of use and ability to ensure consistent pastry quality. However, drying and mixing are crucial steps in the production of premixed pastry powders, and their effectiveness directly affects the quality of the finished powder.
[0003] Traditional premixed pastry production methods typically involve separate steps for drying and mixing. First, the raw materials are dried using specialized drying equipment, then transferred to mixing equipment for further blending. This step-by-step process not only increases the complexity of the production process and extends the production cycle but also raises production costs. Furthermore, during the raw material transfer process, the materials are susceptible to external environmental factors, leading to contamination and affecting the quality of the premixed pastry powder. In addition, a separate sieving process is required before the drying and mixing process to remove agglomerated particles from the powder, which undoubtedly increases the actual processing steps and affects the overall processing efficiency. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated mixing and drying device for premixed pastry powder. During use, this device utilizes a stirring mechanism in conjunction with a powder movement mechanism to improve the uniformity and effectiveness of drying and mixing. Furthermore, it can process lumpy powder during operation to ensure the quality of the finished powder.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An integrated mixing and drying device for premixed pastry powder includes a housing with a base fixedly connected to its lower end. An electric heating plate is embedded in the inner wall of the bottom portion of the housing.

A rotatable shaft is located at the top inner part of the housing, with its lower end penetrating the connecting cylinder and fixedly connected to multiple inclined stirring blades. A spiral blade is fixedly connected to the outer side of the inner portion of the connecting cylinder. A discharge port is located on the top inner side wall of the connecting cylinder. When the shaft rotates, the spiral blades allow the powder inside the housing to move and mix, achieving simultaneous mixing and drying in conjunction with the electric heating plate. A clumping removal mechanism removes and breaks up clumped particles in the powder. A moisture removal mechanism removes moisture from inside the housing to ensure effective drying.
[0006] Preferably, a sealable feeding port is provided at the inner top of the housing, and a powder pump is installed at the inner bottom of the housing, with the powder inlet of the powder pump extending to the inner bottom of the housing.
[0007] Preferably, it further includes a drive mechanism, which includes a motor mounted on the upper end of the housing, the upper end of the rotating shaft extending to the outside and fixedly connected to a first gear, the output shaft of the motor being fixedly connected to a second gear, the first gear meshing with the second gear, and a protective frame fixedly connected to the upper end of the housing.
[0008] Preferably, the clumping removal mechanism includes a rotating column fixedly sleeved on the outside of a rotating shaft. A fixed cylinder is sleeved on the outside of the rotating column. Two guide grooves are symmetrically opened on the inner side of the fixed cylinder. Guide strips are fixedly connected to both sides of the rotating column. The outer sides of the two guide strips extend into the corresponding guide grooves and are slidably connected. The lower end of the rotating column is elastically connected to the inner bottom of the fixed cylinder by a second spring. A first rotating disk is fixedly connected to the outside of the fixed cylinder. Multiple reinforcing rods are connected to the lower end of the first rotating disk. A second rotating disk is fixedly connected to the lower end of the multiple reinforcing rods. A conical separation disk is fixedly connected to the middle of the second rotating disk. Multiple separation holes are opened on the conical separation disk. The conical separation disk is sleeved on the outside of the connecting cylinder and is slidably connected.
[0009] Preferably, it further includes a shaking mechanism, which includes a connecting plate fixedly connected to the upper end of the connecting cylinder. The upper end of the connecting plate is circumferentially and equally spacedly connected with a plurality of second abutments. The lower end of the first rotating disk is fixedly connected with a first abutment. The first abutment cooperates with the plurality of second abutments. The upper part of the connecting cylinder is fixedly connected with arc-shaped impact plates on both the front and rear sides.
[0010] Preferably, the second rotating disk has multiple material feeding ports at equal intervals, and the first rotating disk has a vertical pipe running through it. The vertical pipe is fixedly connected to the first rotating disk, and the upper end of the vertical pipe is matched with the feeding port.
[0011] Preferably, the moisture removal mechanism includes a mounting base fixedly connected to the upper end of the housing, a drying cylinder mounted on the upper end of the mounting base, a filter element installed inside the drying cylinder, a columnar cavity provided inside the mounting base, two arc-shaped cavities symmetrically arranged on the inner wall of the housing, and a communication port opened on the inner side of each of the two arc-shaped cavities, a piston cylinder mounted on the upper end of the housing, the rear space of the piston cylinder communicating with the right arc-shaped cavity through a second one-way pipe, the rear space of the piston cylinder communicating with the left space of the drying cylinder through a first one-way pipe, the right space of the drying cylinder communicating with the right space of the columnar cavity through a connecting pipe, the middle space of the columnar cavity communicating with the left arc-shaped cavity through a connecting pipe, and a rotating ring that fits against and slides against the inner wall of the housing is fixedly connected to the outer sides of the first rotating disk and the second rotating disk, and the rotating ring is provided with multiple filter holes.
[0012] Preferably, both the first one-way tube and the second one-way tube are equipped with one-way valves. The one-way flow direction inside the first one-way tube is that the piston cylinder enters the drying cylinder in one direction, and the one-way valve inside the second one-way tube allows the flow direction to be one-way into the piston cylinder through the right arc-shaped cavity.
[0013] Preferably, a drive disc is fixedly connected to the upper end of the rotating shaft, a connecting rod is rotatably connected to the upper eccentric part of the drive disc, a piston plate that can slide back and forth is provided inside the piston cylinder, and the other end of the connecting rod is rotatably connected to the front side of the piston plate.
[0014] Preferably, the cylindrical cavity is provided with a piston column that can slide left and right. The right side of the piston column is elastically connected to the right side wall of the cylindrical cavity via a first spring. Both the left and right spaces of the cylindrical cavity are connected to the outside through vent holes. An electromagnetic valve is installed in the vent hole on the right side.
[0015] Compared with the prior art, the beneficial effects of this invention are as follows: 1. This invention uses a motor-driven gear to rotate, which in turn rotates the shaft. This causes the spiral blades to transport the powder from the bottom to the top, while the remaining powder moves downwards due to gravity, achieving powder mixing. Combined with an electric heating plate, this enables simultaneous mixing and drying, improving overall efficiency. The inclined stirring blades at the lower end of the shaft increase the contact area with the powder, further enhancing the mixing effect and effectively improving drying efficiency and uniformity, ensuring the powder is fully dried.
[0016] 2. After the powder is transported to the top of the connecting cylinder, it is discharged from the discharge port and falls onto the conical separating disc. Agglomerated particles, unable to pass through the separation holes, are sieved. The first rotating disc, in conjunction with the connecting disc's abutment block and the action of the second spring, causes the connecting cylinder to vibrate, which in turn drives the conical separating disc to vibrate, improving separation efficiency and breaking up agglomerated particles. The arc-shaped impact plate further assists in breaking up the difficult-to-disperse agglomerated particles, improving the overall processing effect and further ensuring the actual drying uniformity.
[0017] 3. The rotating shaft drives the rotating disk to rotate, and the piston plate moves back and forth through the connecting rod. After the feeding port is sealed, some of the gas inside the shell is first extracted, causing the piston column to move to the left and expose the connecting pipe, thus forming an internal circulating airflow. The filter element inside the drying cylinder filters the moisture in the airflow, achieving circulating moisture removal and preventing moisture from affecting drying. At the same time, it keeps the inside of the shell under negative pressure, lowering the drying boiling point and promoting efficient drying.
[0018] 4. The rotating ring moves in tandem with the first and second rotating discs, filtering floating powder through its filter holes to prevent powder from entering the moisture removal mechanism and thus avoiding waste. The shaking of the rotating ring makes it easy for powder adhering to the filter holes to detach, ensuring continuous use. The rotation causes the filter holes to reciprocate in the arc-shaped cavity, generating suction and blowing forces, achieving self-cleaning and further improving the continuous use performance of the filter structure during equipment operation.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0022] Reference Figures 1-10 An integrated mixing and drying device for premixed pastry powder includes a shell 1. A base 2 is fixedly connected to the lower end of the shell 1. The base 2 is made of high-strength metal material, which has good stability and load-bearing capacity, ensuring that the device remains stable during operation and preventing tipping due to vibration or other reasons. A sealable feeding port 4 is provided at the inner top of the shell 1. The feeding port 4 is open during feeding and in the initial stage of heating. When the internal temperature reaches the drying temperature, the feeding port 4 is sealed. A powder pump 10 is installed at the inner bottom of the shell 1. The powder inlet of the powder pump 10 extends to the inner bottom of the shell 1. An electric heating plate is embedded in the inner wall of the bottom part of the shell 1. After the electric heating plate is started, it can heat and dry the powder inside. The electric heating plate uses a high-efficiency and energy-saving heating element, which can quickly heat up and maintain a stable heating temperature, thereby improving the drying efficiency. The system also includes a powder motion mechanism, which includes a connecting cylinder 11 located inside the housing 1. The connecting cylinder 11 is fixedly connected to the inner wall of the housing 1 by multiple fixing strips 32. A rotatable shaft 12 is provided at the top inner part of the housing 1. The lower end of the shaft 12 passes through the connecting cylinder 11 and is fixedly connected to multiple inclined stirring blades 14. The design of the inclined stirring blades 14 can increase the contact area with the powder and improve the stirring effect. A spiral blade 13 is fixedly connected to the outer side of the inner part of the shaft 12. A discharge port 40 is provided on the inner top side wall of the connecting cylinder 11. When the shaft 12 rotates, the spiral blades 13 can be used to transport the bottom powder inside the housing 1 to the top, and the remaining powder moves downward under gravity, realizing the movement and mixing of the powder. With the use of an electric heating plate, the mixing and drying can be carried out simultaneously. The device also includes a drive mechanism, which includes a motor 22 mounted on the upper end of the housing 1, an upper end of a rotating shaft 12 extending to the outside and fixedly connected to a first gear 23, and a second gear 24 fixedly connected to the output shaft of the motor 22. The first gear 23 and the second gear 24 mesh with each other. A protective frame 3 is fixedly connected to the upper end of the housing 1. The protective frame 3 can prevent the first gear 23 and the second gear 24 from being directly exposed to the outside, thus improving the safety of the device. The system also includes a clumping removal mechanism, which removes and breaks up clumped particles in the powder. The clumping removal mechanism includes a rotating column 43 fixedly sleeved on the outside of the rotating shaft 12. A fixed cylinder 35 is sleeved on the outside of the rotating column 43. Two guide grooves 45 are symmetrically formed on the inner side of the fixed cylinder 35. Guide strips 46 are fixedly connected to both sides of the rotating column 43. The outer sides of the two guide strips 46 extend into the corresponding guide grooves 45 and are slidably connected. The lower end of the rotating column 43 is elastically connected to the inner bottom of the fixed cylinder 35 via a second spring 44. A first rotating disk 33 is fixedly connected to the outside of the fixed cylinder 35. Multiple reinforcing rods 36 are connected to the lower end of the first rotating disk 33. A second rotating disk 34 is fixedly connected to the lower end, and a conical separation disk 38 is fixedly connected to the middle of the second rotating disk 34. The conical separation disk 38 has multiple separation holes 39. The size of the separation holes 39 is designed according to the particle size requirements of the powder, which can effectively separate agglomerated particles. Furthermore, in this solution, in order to avoid stratification, the various types of premixed powder can be separated into particles of similar size during the pretreatment stage. The conical separation disk 38 is sleeved on the outside of the connecting cylinder 11 and is slidably connected. When the powder is transported to the top of the connecting cylinder 11 and discharged from the discharge port 40, it will fall onto the conical separation disk 38. Through the separation holes 39, the agglomerated particles in the powder can be separated and remain on the conical separation disk 38. The system also includes a shaking mechanism, which comprises a connecting plate 47 fixedly connected to the upper end of the connecting cylinder 11. Multiple second abutments 15 are fixedly connected at equal intervals in a circular shape at the upper end of the connecting plate 47. A first abutment 42 is fixedly connected to the lower end of the first rotating disk 33, and the first abutment 42 cooperates with the multiple second abutments 15. Arc-shaped impact plates 41 are fixedly connected to both the front and rear sides of the upper part of the connecting cylinder 11. Multiple material discharge ports 37 are evenly spaced on the second rotating disk 34. A vertical pipe 18 is threaded through the first rotating disk 33. The tube 18 is fixedly connected to the first rotating disk 33. The upper end of the vertical tube 18 is matched with the feeding port 4. When the shaking mechanism is running, the cone-shaped separation disk 38 can be shaken to improve the separation efficiency. In addition, the particles that have been screened can be shaken apart to break up the agglomerates. With the use of the arc-shaped impact plate 41, some agglomerated particles that are difficult to shake apart can collide with the arc-shaped impact plate 41 with the shaking, which improves the crushing effect of the agglomerated particles. It should be noted that the upper end face of the arc-shaped impact plate 41 is arc-shaped. The system also includes a moisture removal mechanism, which removes moisture from inside the housing 1 to ensure a drying effect. The moisture removal mechanism includes a mounting base 5 fixedly connected to the upper end of the housing 1. A drying cylinder 6 is mounted on the upper end of the mounting base 5, and a filter element 20 is installed inside the drying cylinder 6. A cylindrical cavity 16 is provided inside the mounting base 5. Two arc-shaped cavities 27 are symmetrically arranged on the inner wall of the housing 1, and each arc-shaped cavity 27 has a connecting opening 28 on its inner side. A piston cylinder 21 is mounted on the upper end of the housing 1. The rear space of the piston cylinder 21 is connected to the right arc-shaped cavity 27 through a second one-way pipe 8. The space is connected to the left space of the drying cylinder 6 through the first one-way pipe 7. The right space of the drying cylinder 6 is connected to the right space of the columnar cavity 16 through the connecting pipe. The middle space of the columnar cavity 16 is connected to the arc-shaped cavity 27 on the left through the connecting pipe 9. The outer sides of the first rotating disk 33 and the second rotating disk 34 are fixedly connected to a rotating ring 29 that fits against and slides against the inner wall of the shell 1. The rotating ring 29 is provided with multiple filter holes 30. The floating powder can be filtered through the filter holes 30 to prevent the powder from entering the moisture removal mechanism and affecting the operation of the moisture removal mechanism. In addition, it can also avoid the waste of powder. The aforementioned rotating ring 29 also moves along with the rotation and shaking of the first rotating disk 33 and the second rotating disk 34. Therefore, the rotating ring 29 also shakes and rotates. The shaking process allows the powder adhering to the filter hole 31 to easily detach, ensuring the continuous usability of the filter hole 30. The continuous use during the rotation process allows the filter hole 30 to move back and forth between the left arc cavity 27 and the right arc cavity 27, thereby generating suction and blowing forces on the side of the filter hole 30 close to the arc cavity 27. The suction process can adsorb the powder, and the blowing process can detach the powder, which can clear the blockage of the filter hole 30, achieve self-cleaning, and further improve the actual continuous usability. Furthermore, both the first one-way pipe 7 and the second one-way pipe 8 are equipped with one-way valves. The one-way flow direction inside the first one-way pipe 7 is that the piston cylinder 21 enters the drying cylinder 6 in one direction. The one-way valve inside the second one-way pipe 8 has the flow direction that the right arc-shaped cavity 27 enters the piston cylinder 21 in one direction. The upper end of the rotating shaft 12 is fixedly connected to the drive disc 25. The upper end of the drive disc 25 is eccentrically connected to the connecting rod 26. The piston cylinder 21 is provided with a piston plate 31 that can slide back and forth. The other end of the connecting rod 26 is rotatably connected to the front side of the piston plate 31. When the piston plate 31 moves forward, it can generate negative pressure in the space behind the piston cylinder 21. When the piston plate 31 moves backward, it can generate high pressure in the space behind the piston cylinder 21. It should be noted that a piston rod 17, which can slide left and right, is installed inside the cylindrical cavity 16. The right side of the piston rod 17 is elastically connected to the right side wall of the cylindrical cavity 16 via a first spring 19. The first spring 19 is a spring with a large stiffness coefficient. Using this method, in the initial stage of operation of the moisture removal mechanism (when the feeding port 4 is already sealed), some of the gas inside the housing 1 can be drawn into the right side space of the cylindrical cavity 16, causing the piston rod 17 to move to the left and stretch the first spring 19. When there is a large amount of gas in the right side space of the cylindrical cavity 16, the gas pressure is high enough to allow the piston rod 17 to move to the left and stretch the first spring 19. After the piston column 17 moves to the left by a large margin, exposing the connection between the connecting pipe 9 and the columnar cavity 16, the continued operation of the moisture removal mechanism can generate circulating airflow inside the housing 1, the right arc-shaped cavity 27, the piston cylinder 21, the drying cylinder 6, the columnar cavity 16, the left arc-shaped cavity 27, and the housing 1 to remove moisture. At the same time, the inside of the housing 1 is under negative pressure to lower the drying boiling point and promote drying. The left and right spaces of the columnar cavity 16 are connected to the outside through vent holes. A solenoid valve is installed in the vent hole on the right side for easy resetting later.
[0023] In this invention, materials are fed through a sealable feeding port 4 at the top of the housing 1. Simultaneously, an electric heating plate embedded in the inner wall of the bottom part of the housing 1 is activated, using a high-efficiency and energy-saving heating element to rapidly raise the temperature and maintain a stable heating temperature, thereby heating and drying the internal powder. During feeding and in the initial heating stage, the feeding port 4 is in the open state. Once the internal temperature reaches the drying temperature, the feeding port 4 is sealed.
[0024] Subsequently, the motor 22 installed on the upper end of the housing 1 starts, and its output shaft drives the second gear 24 to rotate. The first gear 23, which meshes with the second gear 24, rotates accordingly, thereby driving the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, the spiral blades 13 fixed on the outer side of the inner part of the connecting cylinder 11 transport the powder at the bottom of the housing 1 to the top, while the remaining powder moves downward under gravity, realizing the movement and mixing of the powder. With the use of the electric heating plate, the mixing and drying are carried out simultaneously. Multiple inclined stirring blades 14, which penetrate the connecting cylinder 11 and are fixed at the lower end of the rotating shaft 12, increase the contact area with the powder and further improve the stirring effect.
[0025] The rotation of the rotating shaft 12 drives the rotating column 43, which is fixedly sleeved on its outer side, to rotate. The rotating column 43 is connected to the guide groove 45 on the inner side of the fixed cylinder 35 through the cooperation of the guide strip 46 and the elastic connection of the second spring 44, so that the fixed cylinder 35 has a certain amount of room to move relative to the rotating column 43. The fixed cylinder 35 drives the first rotating disk 33, the reinforcing rod 36, the second rotating disk 34, and the conical separation disk 38 to rotate. When the powder is transported to the top of the connecting cylinder 11, it is discharged from the discharge port 40 and falls onto the conical separation disk 38. The agglomerated particles in the powder cannot be separated because they cannot pass through the separation hole 39 designed according to the particle size requirements of the powder, and remain on the conical separation disk 38.
[0026] When the first rotating disk 33 rotates, its lower end first abutment block 42 cooperates with multiple second abutment blocks 15 fixed at equal intervals in a circular shape at the upper end of the connecting disk 47. Simultaneously, the use of the second spring 44 causes the fixed cylinder 35 to vibrate, which in turn drives the conical separating disk 38 to vibrate, improving separation efficiency and breaking up clumps of particles. Furthermore, the arc-shaped impact plates 41 fixed to the front and rear sides of the upper part of the connecting cylinder 11 cause some clumps that are difficult to break up to impact the arc-shaped impact plates 41 due to the vibration and their own interaction, further improving the breaking effect of the clumps.
[0027] The rotation of the shaft 12 drives the drive disc 25 to rotate. The connecting rod 26, which is eccentrically connected at the upper end of the drive disc 25, drives the piston plate 31, which can slide back and forth inside the piston cylinder 21, to move back and forth. The forward movement of the piston plate 31 creates a negative pressure in the space behind the piston cylinder 21, drawing gas from the right arc-shaped cavity 27 into the space behind the piston cylinder 21 through the second one-way pipe 8. The backward movement of the piston plate 31 creates a high pressure in the space behind the piston cylinder 21, forcing gas into the space on the left side of the drying cylinder 6 through the first one-way pipe 7, and then into the space on the right side of the columnar cavity 16 through the connecting pipe. In the initial stage of operation of the moisture removal mechanism (with the feeding port 4 sealed), this process extracts some of the gas inside the shell 1 to the right side of the columnar cavity 16, causing the piston column 17 to move to the left and stretch the first spring 19. When there is a large amount of gas in the right side of the columnar cavity 16, and the gas pressure is sufficient to allow the piston column 17 to move to the left by a large amount, exposing the connection between the connecting pipe 9 and the columnar cavity 16, the piston plate 31 continues to move back and forth, generating a circulating airflow inside the shell 1, the right arc-shaped cavity 27, the piston cylinder 21, the drying cylinder 6, the columnar cavity 16, the left arc-shaped cavity 27, and inside the shell 1. The filter element 20 inside the drying cylinder 6 filters and removes moisture from the airflow, achieving circulating moisture removal. At the same time, it keeps the inside of the shell 1 under negative pressure, lowering the drying boiling point and promoting drying. During the aforementioned gas circulation process, the rotating ring 29, which is fixedly connected to the outer sides of the first rotating disk 33 and the second rotating disk 34, moves with the rotation and vibration of the first rotating disk 33 and the second rotating disk 34. The filter holes 30 on the rotating ring 29 filter the floating powder, preventing the powder from entering the moisture removal mechanism and affecting its operation, while also preventing powder waste. The vibration of the rotating ring 29 makes it easier for the powder adhering to the filter holes 31 to detach, ensuring the continuous usability of the filter holes 30; the rotation of the rotating ring 29 causes the filter holes 30 to move back and forth between the left and right arc-shaped cavities 27, generating suction and blowing forces on the side of the filter holes 30 closest to the arc-shaped cavities 27. The suction force adsorbs the powder, and the blowing force detaches the powder, thus clearing the blockage of the filter holes 30 and further improving continuous usability.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
