Description

Technical Field

[0001] This application relates to the field of collagen production technology, and in particular to a spray drying granulation apparatus for collagen production. Background Technology

[0002] The spray drying granulation device for collagen production is a device that converts collagen solution into granular products through spray drying technology. It is widely used in food, medicine, cosmetics and other fields.

[0003] The collagen solution is delivered to a nozzle via a high-pressure pump, where it is atomized into fine droplets using pressure or centrifugal force. These atomized droplets come into contact with hot air, rapidly evaporating moisture and forming dry particles.

[0004] In existing granulation equipment, the atomizing nozzles of the hot air pipe and the feed pipe work together to allow the atomized droplets to come into contact with the hot air, which facilitates the processing and drying of materials and facilitates production. However, the atomizing nozzles of the feed pipe are relatively fixed, making it difficult to adjust the spray trajectory of the atomizing nozzles, which can easily affect the uniform drying of materials. In addition, the single hot air pipe is not conducive to the uniform distribution of heating airflow, affecting the uniformity of material drying and making it easy for materials to stick to the barrel wall, which is not conducive to the drying process of materials. Utility Model Content

[0005] The purpose of this application is to address the problems in existing granulation equipment. While the atomizing nozzles in the hot air duct and feed pipe facilitate contact between the atomized droplets and hot air for material processing and drying, the fixed position of the atomizing nozzles in the feed pipe makes it difficult to adjust their spray trajectory, which can affect the uniform drying of the material. Furthermore, the single hot air duct makes it difficult to evenly distribute the heating airflow, affecting the uniformity of material drying and causing material to adhere to the barrel wall, hindering the drying process. This application provides a spray drying granulation device for collagen production.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A spray drying granulation device for collagen production includes a frame with support legs fixed at each of the four corners of the lower end. A drying barrel is fixed inside the frame, and a cover plate is installed on the upper end of the drying barrel. A feed pipe is fixed on the cover plate and extends into the drying barrel. A fan is fixed on the frame, and a ventilation pipe is fixed to the air outlet of the fan. The ventilation pipe is U-shaped, and an air inlet pipe is fixed to the end of the ventilation pipe away from the fan, extending into the drying barrel. An air inlet pipe is fixed to the lower end of the ventilation pipe, and an electric heater is fixed to both air inlet pipes. An air outlet pipe is fixed on the cover plate, and a horn tube is fixed to the lower end of the drying barrel. A controller is fixed on the cover plate, and a drying mechanism is provided between the cover plate and the horn tube.

[0008] By adopting the above technical solution and through the drying mechanism, it is easy to uniformly distribute the heating airflow, uniformly distribute the atomized material, uniformly granulate the material, reduce the material adhering to the inner wall of the barrel, and facilitate the processing and production of the material.

[0009] Furthermore, the drying mechanism includes a fixed pipe fixed to one end of the air inlet pipe, and air inlets are fixed on the fixed pipe and arranged in an array. The air inlets correspond to the air inlet pipe. The fixed pipe is located at the lower end of the drying barrel. An adjustment component is provided between the drying barrel and the cover plate.

[0010] By adopting the above technical solution, the heated air enters the second air inlet pipe and then enters the fixed pipe, so that the heated air is sprayed out from the air inlet head and blows against the inner wall of the drying barrel in a circular array, which facilitates the uniform distribution of the heated airflow.

[0011] Furthermore, the adjustment assembly includes a telescopic tube fixed to the lower end of the feed pipe, an atomizing nozzle fixed to the lower end of the telescopic tube, the atomizing nozzles being arranged in a circular array, an electric telescopic rod fixed to the cover plate, the telescopic end of the electric telescopic rod extending into the drying barrel and fixedly connected to the atomizing nozzle, and a limiting component being provided between the atomizing nozzle and the cover plate.

[0012] By adopting the above technical solution, the electric telescopic rod extends and retracts, driving multiple atomizing nozzles to move up and down, which facilitates uniform contact between the material and the heated airflow.

[0013] Furthermore, the limiting component includes a limiting post slidably disposed on the cover plate, the limiting post extending into the drying barrel and fixedly connected to the atomizing nozzle, and an insulation layer fixed on the drying barrel.

[0014] By adopting the above technical solution, the column is restricted from sliding on the cover plate, thus limiting the atomizing nozzle and facilitating uniform drying.

[0015] Furthermore, both the first and second air inlet pipes are equipped with solenoid valves, which are electrically connected to the controller, and the controller is electrically connected to the electric heater.

[0016] By adopting the above technical solution, the solenoid valves on the air outlet pipe 1 and air outlet pipe 2 of the controller can adjust the airflow size, which facilitates the uniform heating and processing of materials.

[0017] Furthermore, the insulation layer is an aluminum silicate cotton layer.

[0018] By adopting the above technical solutions, the heat preservation effect of the drying drum is improved and heat loss is reduced.

[0019] Furthermore, the telescopic tube is a flexible metal tube, a temperature sensor is fixed on the drying barrel, the detection end of the temperature sensor extends into the drying barrel, and the controller is electrically connected to the temperature sensor.

[0020] By adopting the above technical solution, the metal flexible hose can be extended and retracted to facilitate the up and down movement adjustment of the atomizing nozzle, which in turn facilitates the uniform drying and heating of materials.

[0021] Furthermore, a screening box is fixed to the lower end of the horn tube, a screen plate is fixed inside the screening box, the screen plate is inclined, a collection box is slidably arranged at the lower end of the screening box, the collection box corresponds to the screen plate, a receiving box is fixed to one side of the screening box, a fixing opening is opened on the screening box, and the receiving box corresponds to the fixing opening.

[0022] By adopting the above technical solution, the sieve plate in the screening box facilitates the screening of granulated materials. Materials that meet the requirements pass through the inclined sieve plate and enter the receiving box, while materials that do not meet the requirements fall through the sieve plate and enter the collection box, which facilitates the recycling and processing of materials.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. When the granulation device is in use, heated air enters the second air inlet pipe and then the fixed pipe, causing the heated air to be sprayed out from the air inlet head. The circular array of air blows against the inner wall of the drying barrel, which facilitates the uniform distribution of the heated airflow, facilitates drying, and reduces material adhesion to the inner wall of the drying barrel. This, together with the first air inlet pipe, forms convection, which facilitates uniform heating of the material. At the same time, the electric telescopic rod extends and retracts, driving multiple atomizing nozzles to move up and down, causing the limiting column to slide on the cover plate, restricting the atomizing nozzles. This extension and retraction of the telescopic pipe facilitates uniform contact with the heated airflow, ensuring uniform heating of the material and improving the processing quality. Through the drying mechanism, the uniform distribution of the heated airflow and atomized material is facilitated, resulting in uniform granulation of the material and reducing material adhesion to the inner wall of the barrel, thus facilitating material processing and production.

[0025] 2. When the granulation device is in use, the metal flexible hose can be extended and retracted to facilitate the up and down movement and adjustment of the atomizing nozzle. Then, the temperature sensor detects the temperature inside the drying barrel and feeds the detection results back to the controller in real time. The controller controls the heating temperature of the electric heater to ensure that the material is at a suitable heating temperature and to facilitate uniform drying of the material.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a spray drying granulation apparatus for collagen production.

[0034] Reference Figures 1-3 A spray drying granulation device for collagen production includes a frame 1, with support legs 2 fixed at the four corners of the lower end of the frame 1. A drying barrel 3 is fixed inside the frame 1, and a cover plate 5 is installed on the upper end of the drying barrel 3. A feed pipe 4 is fixed on the cover plate 5 and extends into the drying barrel 3. A fan 6 is fixed on the frame 1, and a ventilation pipe 7 is fixed at the air outlet end of the fan 6. The ventilation pipe 7 is U-shaped, and an air inlet pipe 8 is fixed at the end of the ventilation pipe 7 away from the fan 6. The air inlet pipe 8 extends into the drying barrel 3. An air inlet pipe 10 is fixed at the lower end of the ventilation pipe 7. Electric heaters 9 are fixed on both the air inlet pipe 8 and the air inlet pipe 10. An air outlet pipe 18 is fixed on the cover plate 5. A horn pipe 13 is fixed at the lower end of the drying barrel 3. A controller 19 is fixed on the cover plate 5. A drying mechanism is provided between the cover plate 5 and the horn pipe 13.

[0035] When the granulation device is in use, the operator feeds the stirred collagen solution into the drying barrel 3 through the feed pipe 4, then starts the blower 6 to blow air into the drying barrel 3, and works with the electric heater 9 to heat and dry the material. The circulating air is discharged from the air outlet pipe 18, which facilitates the processing and production of the material. The drying mechanism facilitates the uniform distribution of the heating airflow, the uniform distribution of the atomized material, and the uniform granulation of the material, reducing the amount of material adhering to the inner wall of the barrel, and facilitating the processing and production of the material.

[0036] Reference Figure 3 and Figure 4The drying mechanism includes a fixed pipe 11 fixed to one end of the air inlet pipe 10. Air inlet heads 12 are fixed to the fixed pipe 11 and arranged in an array. The air inlet heads 12 correspond to the air inlet pipe 8. The fixed pipe 11 is located at the lower end of the drying barrel 3. An adjustment assembly is provided between the drying barrel 3 and the cover plate 5. The adjustment assembly includes a telescopic pipe 16 fixed to the lower end of the feed pipe 4. Atomizing nozzles 17 are fixed to the lower end of the telescopic pipe 16 and arranged in a circular array. An electric telescopic rod 14 is fixed to the cover plate 5. The telescopic end of the electric telescopic rod 14 extends into the drying barrel 3 and is fixedly connected to the atomizing nozzles 17. A limiting component is provided between the atomizing nozzles 17 and the cover plate 5. The limiting component includes a limiting post 15 slidably mounted on the cover plate 5. The limiting post 15 extends into the drying barrel 3 and is fixedly connected to the atomizing nozzles 17. A heat insulation layer 26 is fixed to the drying barrel 3. Solenoid valves 20 are fixed on both air inlet duct 1 (8) and air inlet duct 2 (10). Solenoid valves 20 are electrically connected to controller 19, and controller 19 is electrically connected to electric heater 9. The insulation layer 26 is an aluminum silicate cotton layer.

[0037] When the granulation device is in use, the air blown by the blower 6 enters the air inlet pipe 8 and comes into contact with the atomized material for drying and heating. The electric heater 9 heats the blown air to facilitate the drying of the material. The heated air enters the air inlet pipe 10 and then enters the fixed pipe 11, so that the heated air is sprayed out from the air inlet head 12. The circular array of air blows against the inner wall of the drying barrel 3, which facilitates the uniform distribution of the heated airflow, facilitates drying, and reduces the material adhering to the inner wall of the drying barrel 3. Together with the air inlet pipe 8, it forms convection to facilitate uniform heating of the material. At the same time, the electric telescopic rod 14 extends and retracts, driving multiple atomizing nozzles 17 to move up and down, so that the limiting column 15 is on the cover plate. The sliding mechanism 5 restricts the atomizing nozzle 17, allowing the telescopic tube 16 to extend and retract, facilitating uniform contact with the heating airflow, uniform heating of the material, and improved processing quality. The controller 19, via the solenoid valves 20 on the air outlet pipes 18-1 and 18-2, adjusts the airflow, ensuring uniform heating and processing of the material. The insulation layer 26, made of aluminum silicate cotton, enhances the insulation of the drying drum 3, reducing heat loss. The drying mechanism facilitates uniform distribution of the heating airflow, uniform distribution of the atomized material, and uniform granulation of the material, reducing material adhesion to the inner wall of the drum and facilitating material processing.

[0038] Reference Figure 3 The telescopic tube 16 is a flexible metal tube. A temperature sensor is fixed on the drying barrel 3, and the sensing end of the temperature sensor extends into the drying barrel 3. The controller 19 is electrically connected to the temperature sensor. A screening box 22 is fixed to the lower end of the horn tube 13. A screen plate 23 is fixed inside the screening box 22. The screen plate 23 is inclined. A collection box 24 is slidably installed at the lower end of the screening box 22. The collection box 24 corresponds to the screen plate 23. A receiving box 25 is fixed to one side of the screening box 22. A fixing opening is opened on the screening box 22, and the receiving box 25 corresponds to the fixing opening.

[0039] When the granulation device is in use, the metal flexible hose can be extended and retracted to facilitate the up and down movement adjustment of the atomizing nozzle 17. Then, the temperature sensor detects the temperature inside the drying barrel 3 and feeds the detection result back to the controller 19 in real time. The controller 19 controls the heating temperature of the electric heater 9 to ensure that the material is at a suitable heating temperature, which facilitates uniform drying and granulation. The sieve plate 23 in the screening box 22 facilitates the screening of the granulated material. The material that meets the requirements passes through the inclined sieve plate 23 and enters the receiving box 25, while the material that does not meet the requirements falls off the sieve plate 23 and enters the collection box 24, which facilitates the recycling and processing of the material, reduces waste, and improves the uniformity of granulation.

[0040] The implementation principle of the spray drying granulation device for collagen production in this embodiment is as follows: When the granulation device is in use, the operator feeds the stirred collagen solution into the drying barrel 3 through the feed pipe 4, and then starts the blower 6 to blow air into the drying barrel 3 in conjunction with the electric heater 9 to heat and dry the material. The circulating air is discharged from the air outlet pipe 18, which facilitates the processing and production of the material.

[0041] When the granulation device is in use, the air blown by the blower 6 enters through the air inlet pipe 8, and comes into contact with the atomized material for drying and heating. The electric heater 9 heats the blown air to facilitate the drying of the material. The heated air enters the second air inlet pipe 10, and then enters the fixed pipe 11, so that the heated air is sprayed out from the air inlet head 12. The circular array of air blows against the inner wall of the drying barrel 3, which facilitates the uniform distribution of the heated airflow, facilitates drying, and reduces material adhesion to the inner wall of the drying barrel 3. Together with the first air inlet pipe 8, it forms convection, which facilitates the uniform heating of the material. When the electric telescopic rod 14 extends and retracts, it drives multiple atomizing nozzles 17 to move up and down, causing the limiting column 15 to slide on the cover plate 5 to restrict the atomizing nozzles 17, and causing the telescopic tube 16 to extend and retract, so as to facilitate uniform contact with the heating airflow, uniform heating of the material, and improved processing quality. Through the controller 19, the solenoid valves 20 on the air outlet pipe 181 and air outlet pipe 182 of the controller 19 can adjust the airflow size, so as to facilitate uniform heating and processing of the material. The insulation layer 26 is an aluminum silicate cotton layer, which improves the insulation effect of the drying barrel 3.

[0042] When the granulation device is in use, the metal hose can be extended and retracted to facilitate the up and down movement adjustment of the atomizing nozzle 17. Then, the temperature sensor detects the temperature inside the drying barrel 3 and feeds the detection result back to the controller 19 in real time. The controller 19 controls the heating temperature of the electric heater 9 to ensure that the material is at a suitable heating temperature, so as to facilitate uniform drying and granulation. The sieve plate 23 in the screening box 22 facilitates the screening of the granulated material. The material that meets the requirements enters the receiving box 25 through the inclined sieve plate 23, while the material that does not meet the requirements falls off the sieve plate 23 and enters the collection box 24.
