Description

Technical Field

[0001] This utility model belongs to the field of soybean flour drying technology, and in particular relates to a soybean flour spray drying device. Background Technology

[0002] The processing of soybean flour involves multiple steps. In order to ensure the storage and transportation of soybean flour, it is necessary to dry it, which requires the use of soybean flour drying equipment.

[0003] Chinese Patent Publication No. CN219756887U discloses a spray drying device for soybean flour processing, including a frame. A sealing plate is fixedly installed inside the top of the frame. A drying chamber is located below the sealing plate on the frame. A hot air supply pipe is fixedly installed at the center of the sealing plate, extending to the bottom of the drying chamber. The bottom end of the hot air supply pipe is closed, and the top end extends to the top of the frame. Two independent drying channels are provided on both sides of the hot air supply pipe, enclosing the inner wall of the frame. Several nozzles leading into the drying channels are symmetrically distributed on both sides of the hot air supply pipe. Inclined baffles are fixedly installed on the inner wall of the frame at the drying chamber and on the outer wall of the hot air supply pipe at the drying chamber. The baffles are alternately distributed in the drying channels. Two spray nozzles symmetrically inserted into the drying air ducts are fixedly installed at the bottom of the sealing plate. The top ends of the spray nozzles are connected to a spray pipe extending to the top of the frame. This invention achieves efficient drying of soybean flour.

[0004] The aforementioned patent has the following problems: This patent has some drawbacks in its use. While it significantly improves the drying efficiency by using alternating baffles to slow the discharge rate of soybean flour within the drying channel, combined with evenly distributed hot air nozzles, this method has certain requirements on the amount of soybean flour entering the system. If the soybean flour enters at a high rate, the discharge rate will increase significantly, and the hot air will be insufficient to completely dry the rapidly flowing soybean flour, resulting in incomplete drying and poor quality. Therefore, we propose a soybean flour spray drying device. Utility Model Content

[0005] The purpose of this invention is to provide a soybean powder spray drying device to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a soybean powder spray drying device, including a tank, a plurality of limiting blocks are fixedly installed on the inner wall of the tank, the same vibrating plate is slidably installed on the surface of the plurality of limiting blocks, and a rotating opening is provided on the lower side of the tank, and a vibrating unit is rotatably installed in the rotating opening; The conveying pipe has a filter plate rotatably installed on the inner wall of the tank. The surface of the filter plate has multiple air holes. The conveying pipe is fixedly installed on the filter plate, and a spray head is fixedly installed at the bottom end of the conveying pipe. Multiple hot air nozzles are fixedly mounted on the tank and extend into the tank, with the ends of the multiple hot air nozzles tilted downwards.

[0007] In this technical solution, undried soybean powder is sprayed into the tank through a conveying pipe and a spray head. Six hot air nozzles installed at equal intervals in a ring on the tank evenly deliver drying hot air into the tank to dry the soybean powder uniformly. The vent holes on the surface of the filter plate can discharge the moisture generated during drying, and the downward tilt of the hot air nozzle ends can prevent soybean powder from sticking to the nozzles and causing blockage. During the drying process, the soybean powder falls onto the vibrating plate. Four limiting blocks are installed at equal intervals on the inner wall of the tank. The four limiting blocks limit the vibrating plate, and the vibrating unit at the bottom makes the vibrating plate vibrate up and down, vibrating and scattering the soybean powder on the upper side, thereby improving the drying efficiency.

[0008] In the above technical solution, the vibration unit further includes a drive disk, which is rotatably installed in a rotation port. A drive rod is fixedly installed on the drive disk, and the vibration plate is slidably installed on the surface of the drive rod. Multiple lower protrusions are fixedly installed on the upper side of the drive disk, and multiple upper protrusions are fixedly installed on the lower side of the vibration plate.

[0009] In this technical solution, the drive disc is located on the lower side of the vibrating plate. The upper protrusion installed on the upper side of the vibrating plate has the same number and size as the lower protrusion installed on the lower side of the drive disc. The drive rod on the drive disc passes through the upper and lower sides of the drive disc. The rotation of the drive rod drives the lower protrusion to move. The lower protrusion squeezes the upper protrusion, causing the vibrating plate to vibrate, thereby scattering the soybean powder.

[0010] In the above technical solution, a base is fixedly installed on the lower side of the tank, and a drive motor is fixedly installed on the base via a connecting rod. The output end of the drive motor is coaxially and fixedly connected to the drive rod.

[0011] In this technical solution, the base is fixed to the drive motor by two connecting rods. The drive motor outputs power to drive the drive rod. The drive motor model can be JGF-5KG.

[0012] In the above technical solution, the lower side of the filter plate is further fixedly connected to the top end of the drive rod.

[0013] In this technical solution, the drive rod is fixedly installed at the circular point of the filter plate, and is used to drive the filter plate and thus drive the spray head to perform circular motion.

[0014] In the above technical solution, further, an annular hollow tube is fixedly installed on the surface of the tank, and a hot air outer pipe is fixedly installed on the surface of the annular hollow tube. The inner ring of the annular hollow tube is connected to multiple hot air nozzles.

[0015] In this technical solution, an annular hollow tube is fitted onto the surface of the tank. The hollow interior is connected to multiple hot air nozzles for air supply, and a hot air external pipe is installed on its outer ring surface for connecting to external hot air.

[0016] In the above technical solution, a can cover is fixedly installed on the upper side of the tank body, an exhaust pipe is fixedly installed on the upper side of the can cover, the conveying pipe is rotatably installed on the can cover via a bearing, a humidity sensor is fixedly installed on the upper side of the filter plate, a controller is fixedly installed on the surface of the annular hollow tube, the controller is electrically connected to the humidity sensor, a discharge port is opened on one side of the tank body, an electronic valve is fixedly installed inside the discharge port, and the electronic valve is electrically connected to the controller.

[0017] In this technical solution, the conveying pipe is installed via bearings to ensure that it does not experience movement limitations during operation. The exhaust pipe on the upper side of the can lid is used to expel moisture. The humidity sensor located between the can lid and the filter plate is an existing humidity sensor used to monitor the humidity in this area to determine the dryness of the soybean powder. The controller electrically connected to it is a PLC controller. During use, the humidity sensor detects the concentration of moisture and transmits the information to the controller. As drying continues, the moisture concentration gradually decreases, and the humidity of the soybean powder gradually decreases. When the set threshold is reached, the controller controls the electronic valve to open. At this time, under the blowing effect of hot air, the soybean powder is discharged outside the can, achieving the effect of automatic discharge of soybean powder.

[0018] In the above technical solution, a rotary joint is further fixedly installed at the top end of the conveying pipe.

[0019] In this technical solution, the rotary joint enables the transition area to be rotatably connected, thereby avoiding the situation where the joint area is limited in movement when the conveying pipe rotates.

[0020] The beneficial effects of this utility model are: 1. This soybean powder spray drying device uses a drive motor to rotate a drive rod, which in turn rotates a filter plate. The filter plate then rotates a spray nozzle, causing the soybean powder to be evenly sprayed into the tank. The powder enters the annular hollow tube through a hot air external pipe and is evenly sprayed into the tank through hot air nozzles for drying. A drive disc then rotates multiple lower protrusions, which in turn press against upper protrusions. Under the action of multiple limiting blocks, the vibrating plate moves up and down, vibrating and scattering the soybean powder to increase the contact area with the hot air, thereby improving drying efficiency and quality.

[0021] 2. In this soybean powder spray drying device, during the drying process, the moisture generated during drying is discharged through the air vents on the filter plate. At this time, the humidity sensor detects the concentration of moisture and transmits the information to the controller. As drying continues, the moisture concentration gradually decreases, and the humidity of the soybean powder gradually decreases. When the set threshold is reached, the controller controls the electronic valve to open. At this time, under the blowing effect of hot air, the soybean powder is discharged outside the tank, achieving the effect of automatic discharge of soybean powder and improving the automation of the device.

[0027] In this process, undried soybean powder is sprayed into the tank 1 through the conveying pipe 8 and the spray head 15. Six hot air nozzles 16, which are installed in a ring at equal intervals on the tank 1, evenly deliver drying hot air into the tank 1 to dry the soybean powder uniformly. The vent holes on the surface of the filter plate 7 can discharge the moisture generated during drying.

The drive rod 17 on the drive plate 18 passes through the upper and lower sides of the drive plate 18. The lower protrusion 19 is driven to move by the rotation of the drive rod 17. The lower protrusion 19 squeezes the upper protrusion 20, causing the vibrating plate 9 to vibrate, thereby scattering the soybean powder.

The lower protrusions 19 move and squeeze the upper protrusions 20. Under the action of multiple limit blocks 10, the vibrating plate 9 moves up and down, vibrating and scattering the soybean powder to increase the contact area with the hot air and improve the drying efficiency. During the drying process, the moisture generated during drying is discharged through the vents on the filter plate 7. At this time, the humidity sensor 13 detects the concentration of moisture and transmits the information to the controller 4. As the drying continues, the moisture concentration gradually decreases, and the humidity of the soybean powder gradually decreases. When the set threshold is reached, the controller 4 controls the electronic valve 5 to open. At this time, under the blowing effect of hot air, the soybean powder is discharged outside the tank 1, completing the drying of the soybean powder.
