[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Example 1

[0031] This invention provides a pressure spray drying tower for the preparation of seabuckthorn peptides, such as... Figures 1 to 5 As shown, the pressure spray drying tower for preparing seabuckthorn peptides includes a drying tower body 1, a drying chamber 2, and a reflux assembly. The drying tower body 1 is used to prepare seabuckthorn peptides, and the drying chamber 2 is used to dry the seabuckthorn peptide solution. The reflux assembly includes a reflux pipe 6, a blower 7, a valve 8, and a filter assembly. The reflux pipe 6 is fixedly connected to the drying tower body 1, the blower 7 is installed on the reflux pipe 6, and the valve 8 is embedded inside the reflux pipe 6. The reflux pipe 6 is used to blow the residual heat airflow into the feed pipe 3 to heat the seabuckthorn peptide solution.

[0032] The filter assembly includes a filter screen 9, an activated carbon adsorbent 10, a mounting frame 11, a rectangular box 12, a mounting rail 13, a magnetic component 14, a sealing component 15, a cover 16, and a positioning component 17. Two mounting frames 11 are provided and are slidably installed inside the rectangular box 12 via the mounting rail 13. The filter screen 9 and the activated carbon adsorbent 10 are respectively installed inside the two mounting frames 11, with the filter screen 9 positioned closer to the drying tower body 1 and the activated carbon adsorbent 10 positioned further away from the drying tower body 1 than the filter screen 9. A magnetic component 14 is embedded in the top of each mounting frame 11. A cover 16 is provided at the bottom of the rectangular box 12, and the cover 16 is fixedly installed at the bottom of the rectangular box 12 via the positioning component 17. A sealing component 15 is sandwiched between the rectangular box 12 and the cover 16.

[0033] In this embodiment, the drying tower body 1 is also connected to a feed pipe 3, an air inlet pipe 4, and an atomizing nozzle 5. The atomizing nozzle 5 is fixedly installed on the top of the drying tower body 1. The feed pipe 3 and the atomizing nozzle 5 are connected. In actual use, the seabuckthorn peptide raw material enters the atomizing nozzle 5 along the feed pipe 3. Under the action of the atomizing nozzle 5, the seabuckthorn peptide liquid is atomized into tiny droplets evenly and efficiently. The end of the air inlet pipe 4 away from the drying tower body 1 is connected to the heating component during use, so that the gas entering the drying tower body 1 through the air inlet pipe 4 is a high-temperature airflow. The high-temperature airflow fully contacts the atomized seabuckthorn peptide droplets inside the drying tower body 1, accelerating the evaporation process of moisture.

[0034] Inside the drying tower body 1, the seabuckthorn peptide solution undergoes rapid evaporation of moisture and drying into solid seabuckthorn peptide particles under the action of high-temperature airflow. The blower 7 draws the residual heat airflow inside the drying tower body 1 into the return pipe 6, and under the conveying action of the blower 7, the residual heat airflow is transported along the return pipe 6 to the air inlet pipe 4. The newly injected high-temperature airflow inside the air inlet pipe 4 mixes with the residual heat airflow and is injected into the drying tower body 1, realizing the reuse of the residual heat airflow.

[0035] An insulation pipe 18 is also fixedly installed on the feed pipe 3. The inner wall of the insulation pipe 18 is lined with insulation cotton 19. The residual heat airflow in the drying chamber 2 is transported to the inside of the insulation pipe 18 through the return pipe 6, so that the insulation pipe 18 accumulates hot air at a higher temperature, thereby initially heating the seabuckthorn peptide solution in the feed pipe 3. The insulation cotton 19 installed inside the insulation pipe 18 can reduce heat loss and ensure that the hot air inside the insulation pipe 18 continuously and stably heats the seabuckthorn peptide solution initially. In specific applications, a valve is also installed on the insulation pipe 18 to discharge the gas inside the insulation pipe 18.

[0036] During operation, the operator feeds the seabuckthorn peptide solution into the atomizing nozzle 5 through the feed pipe 3. The nozzle 5 atomizes the solution into tiny droplets. Simultaneously, a high-temperature airflow is injected into the drying tower body 1 through the air inlet pipe 4, causing the atomized seabuckthorn peptide droplets to rapidly evaporate their moisture. The resulting solid seabuckthorn peptide particles are discharged through the outlet below the drying chamber 2 under their own gravity. The high-temperature airflow pre-injected into the drying tower body 1 mixes with the droplet seabuckthorn peptides, causing their temperature to drop. At this point, the fan 7 begins to operate. The residual heat gas is drawn out from the inside of the drying chamber 2 and blown into the insulation pipe 18 by the return pipe 6. The residual heat gas injected into the insulation pipe 18 can preheat the seabuckthorn peptide solution in the feed pipe 3, so that the seabuckthorn peptide droplets after being atomized by the atomizing nozzle 5 have a certain initial temperature, thereby accelerating the drying process of the seabuckthorn peptide droplets, improving the overall production efficiency, realizing the recycling of residual heat gas, avoiding the waste caused by the direct discharge of residual heat gas, and reducing production costs.

[0037] Specifically, the filter components not only prevent the risk of damage caused by the seabuckthorn peptide dust and impurities being sucked into the fan 7, but also ensure the purity of the return airflow and the heat exchange efficiency; the fan 7 can operate in a more stable and safer environment, extending its service life; at the same time, the heat exchange process is also more efficient, further improving the working efficiency of the drying tower; when the filter screen 9 and activated carbon adsorption element 10 in the rectangular box 12 need to be cleaned or replaced due to long-term use, the cover 16 can be removed by unscrewing the positioning part 17, and then the old filter screen 9 and activated carbon adsorption element 10 inside the rectangular box 12 can be taken out for cleaning or replacement;

[0038] The specific installation process of filter screen 9 and activated carbon adsorbent 10 is as follows: filter screen 9 and activated carbon adsorbent 10 are both embedded inside the mounting frame 11. The mounting frame 11 is slid into the rectangular box 12 along the mounting slide rail 13, so that the magnetic part 14 at the top of the mounting frame 11 is attracted to the top of the inner wall of the rectangular box 12. Then, the sealing part 15 is inserted into the rectangular box 12, and the cover 16 is installed at the bottom of the rectangular box 12 to seal its bottom end. At the same time, the cover 16 is pressed tightly against the sealing part 15 during the installation process to ensure that the gas inside the return pipe 6 will not be discharged along the gap. Then, the positioning part 17 is threaded through the cover 16 and installed into the rectangular box 12 to complete the installation process of filter screen 9 and activated carbon adsorbent 10.

[0039] In order to ensure that the seabuckthorn peptide particles adhering to the inner wall of drying chamber 2 can fall off smoothly, such as Figures 1 to 5 As shown, the spray drying tower also includes a drive unit 20, a scraper 21, a support frame 22, a discharge tray 23, and an inclined plate 24. The drive unit 20 is fixedly installed inside the drying tower body 1. The scraper 21 is connected to the output shaft of the drive unit 20. The support frame 22 is symmetrically arranged on the outside of the discharge tray 23. One end of the two support frames 22 is fixedly connected to the drying chamber 2, and the other end is fixedly connected to the discharge tray 23. The two symmetrically arranged support frames 22 are used to support and fix the discharge tray 23. Inclined plates 24 are also symmetrically fixedly connected to the outer surface of the output shaft of the drive unit 20. Both inclined plates 24 are in contact with the outer surface of the discharge tray 23 and move.

[0040] By energizing the drive unit 20 and driving the scraper 21 to rotate, the scraper 21 rotates and scrapes off the seabuckthorn peptide particles attached to the inner wall of the drying chamber 2. The scraped-off seabuckthorn peptide particles are discharged along the discharge port below the drying chamber 2 under their own gravity. The dried seabuckthorn peptide particles fall onto the surface of the feeding tray 23. The rotating inclined plate 24 can scrape off the seabuckthorn peptide on the feeding tray 23 and drop it into the pre-placed container, avoiding blockage of the discharge port below the drying chamber 2.

[0041] Specifically, the magnetic component 14 is an existing magnet embedded inside the mounting frame 11; the sealing component 15 is a sealing ring made of rubber material; the positioning component 17 can be a screw, which is installed inside the rectangular box 12 by threaded connection; and the driving component 20 is a drive motor.

[0042] Working principle: In actual use, the atomizing nozzle 5 atomizes the seabuckthorn peptide solution into tiny droplets and sprays them evenly into the drying chamber 2. At the same time, the high-temperature airflow is introduced into the drying chamber 2 along the air inlet pipe 4 and quickly evaporates the water in the seabuckthorn peptide droplets. The evaporated seabuckthorn peptide droplets form fixed seabuckthorn peptide particles, which are discharged along the discharge port at the bottom of the drying chamber 2 under their own gravity.

[0043] When fan 7 is working, it draws the residual heat from the drying chamber 2 into the return pipe 6.

[0044] Under the action of the return pipe 6, the waste heat gas is blown into the insulation pipe 18. The waste heat gas injected into the insulation pipe 18 can preheat the seabuckthorn peptide solution in the feed pipe 3, so that the seabuckthorn peptide droplets after being atomized by the atomizing nozzle 5 have a certain initial temperature, thereby accelerating the drying process of the seabuckthorn peptide droplets, improving the overall production efficiency, avoiding the waste heat gas flow directly discharged from the drying tower body 1, and effectively reducing production costs.

[0045] When the drive unit 20 is powered on, it can drive the scraper 21 to rotate inside the drying chamber 2. When the scraper 21 rotates, it scrapes off the seabuckthorn peptide particles attached to the inner wall of the drying chamber 2 and discharges them along the outlet, ensuring that the drying chamber 2 is kept clean. At the same time, the automatic operation of the cleaning component reduces the need for manual cleaning of the inner wall of the drying chamber 2 and reduces labor intensity.

[0046] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
