[0002] With the increasing global demand for natural products, especially berry extracts rich in nutrients and bioactivity, market demand is rising year by year. Berry extracts are widely used in the food, pharmaceutical, and cosmetic industries due to their abundant antioxidants, vitamins, and minerals. However, berry extracts usually need to be dried before use to extend their shelf life and improve their performance.

[0003] Traditional drying methods typically require high temperatures, which not only consumes significant amounts of energy but also leads to the loss or degradation of heat-sensitive components, thus affecting product quality and efficacy. Vacuum low-temperature spray drying technology, due to its unique advantages, is increasingly being widely used in the food, pharmaceutical, and cosmetic industries. This technology can rapidly evaporate moisture at relatively low temperatures, effectively avoiding the damage to heat-sensitive components caused by high temperatures.

[0004] However, despite the numerous advantages of vacuum cryogenic spray drying technology, some problems still exist in practical applications. In existing vacuum cryogenic spray dryers, the extraction tube easily falls out of the material tray due to the lack of a fixing mechanism. This not only affects the smooth progress of the drying process but may also lead to material waste and equipment damage. Currently, no effective solutions have been proposed to address these technical problems. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a vacuum low-temperature spray dryer for berry extracts to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A vacuum low-temperature spray dryer for berry extract includes a worktable with a support frame on one side. The support frame is connected to a drying cylinder. A centrifugal spray head is installed inside the drying cylinder. The top of the centrifugal spray head is connected to the input end of a peristaltic pump via a connecting pipe. The peristaltic pump is fixedly connected to the worktable. The output end of the peristaltic pump is connected to an extraction pipe via a connecting hose. A connecting ring is fixedly connected to the extraction pipe. A slider is connected to one side of the connecting ring via a connecting plate. A slide groove is provided on one side of the worktable, and the slider matches the slide groove. A threaded rod is provided inside the slide groove, and the threaded rod is threadedly connected to the slider.

[0008] Furthermore, one end of the threaded rod is connected to the slide groove via a bearing, and the other end of the threaded rod passes through the slide groove and is connected to the drive motor, which is located at the top of the slide groove.

[0009] Furthermore, the bottom of the drying cylinder is connected to a cyclone separator via a discharge pipe, the top of the cyclone separator is connected to a cold trap via an exhaust pipe, and one side of the cold trap is connected to a vacuum pump via an extraction pipe. The vacuum pump is located inside the workbench, and a vacuum instrument is connected to the top of the cold trap.

[0010] Furthermore, a first collection bottle is threadedly connected to the output end of the cyclone separator, and a second collection bottle is threadedly connected to the bottom end of the drying cylinder.

[0011] Furthermore, an air inlet pipe is provided on one side of the top of the drying cylinder. One end of the air inlet pipe is connected to the heating chamber.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] According to an embodiment of the present invention, a vacuum low-temperature spray dryer for berry extracts is provided.

[0025] Example 1

[0026] like Figures 1-4As shown, the berry extract vacuum low-temperature spray dryer according to an embodiment of the present invention includes a workbench 1, a support frame 2 on one side of the workbench 1, the support frame 2 being connected to a drying cylinder 3, a centrifugal spray head 4 inside the drying cylinder 3, the top of the centrifugal spray head 4 being connected to the input end of a peristaltic pump 5 via a connecting pipe, the peristaltic pump 5 being fixedly connected to the workbench 1, the output end of the peristaltic pump 5 being connected to an extraction pipe 7 via a connecting hose 6, a connecting ring 8 being fixedly connected to the extraction pipe 7, a slider 10 being connected to one side of the connecting ring 8 via a connecting plate 9, and a sliding groove 1 on one side of the workbench 1. 1. The slider 10 matches the slide groove 11. A threaded rod 12 is provided inside the slide groove 11, and the threaded rod 12 is threadedly connected to the slider 10. One end of the threaded rod 12 is connected to the slide groove 11 via a bearing, and the other end passes through the slide groove 11 and is connected to the drive motor 13. The drive motor 13 is fixed to the top of the slide groove 11. A shelf 27 is provided on the outside of the workbench 1 for placing material containers. Universal wheels 28 are connected to the bottom of the workbench 1 for easy movement. An observation window 33 is provided on one side of the drying cylinder 3 for observing the internal condition of the drying cylinder 3. A touch screen display 29 is connected to one side of the workbench 1 for observing the operating parameters of the equipment. An electrical control cabinet 30 is located inside the workbench 1. With the above scheme, by placing the material bucket on the placement plate 27, the drive motor 13 is started, which drives the threaded rod 12 to rotate. The rotation of the threaded rod 12 drives the slider 10 to move. The movement of the slider 10 drives the connecting plate 9 and the extraction tube 7 to move down, so that one end of the extraction tube 7 can contact the bottom of the material bucket, preventing the extraction tube 7 from moving randomly. After the material inside the material bucket is extracted, the extraction tube 7 can be moved up, so that the extraction tube 7 is away from the material bucket, making it easy to remove the material bucket. After the extraction tube 7 is placed, the peristaltic pump 5 can be started. The peristaltic pump 5 can precisely control the delivery speed and flow rate of the liquid material, ensuring that the material can enter the centrifugal spray head 4 stably and continuously. The centrifugal spray head 4 is equipped with a precision nozzle and a rotating mechanism, which can evenly disperse the liquid material into extremely small droplets during high-speed rotation.

[0027] like Figures 1-4As shown, an air inlet pipe 32 is provided on one side of the top of the drying cylinder 3. One end of the air inlet pipe 32 is connected to the heating chamber 31. Heating plates 23 are connected to the inner walls on both sides of the heating chamber 31. A temperature sensor is provided inside the heating chamber 31 to monitor the internal temperature. The bottom of the heating chamber 31 is connected to a fan 25 through an air supply pipe 24. In this dryer, the fan 25 can be a blower or a ventilation fan. One end of the fan 25 is connected to an exhaust pipe 26. The exhaust pipe 26 and the air supply pipe 24 are connected to the workbench 1 through a mounting plate. The heating chamber 31 is located above the mounting plate. A filter screen is bolted to one end of the exhaust pipe 26. One side of the bottom of the drying cylinder 3 is connected to a cyclone separator 15 through a discharge pipe 14. The cyclone separator 15 is connected to the workbench 1 through a connecting rod. The top of the cyclone separator 15 is connected to the cold trap 17 via an exhaust pipe 16. The cold trap 17 is connected to the workbench 1 via a connecting frame. The cold trap 17 mainly includes a container that can hold a cooling medium (such as liquid nitrogen). A coil is installed inside the cavity to cool the gas through the cooling medium. The end of the coil is connected to the body of the cold trap 17 so that the gas is cooled when passing through the coil. A water storage tank is detachably connected to the bottom of the cold trap 17. One side of the cold trap 17 is connected to a vacuum pump 19 via an exhaust pipe 18. The vacuum pump 19 is located inside the workbench 1. A vacuum instrument 20 is connected to the top of the cold trap 17 to monitor the vacuum level inside the drying cylinder 3 in real time. The output end of the cyclone separator 15 is threadedly connected to a first collection bottle 21, and the bottom end of the drying cylinder 3 is threadedly connected to a second collection bottle 22. The above scheme involves evacuating the air inside the drying cylinder 3 by starting the peristaltic pump 5 before starting the vacuum pump 19. After evacuation, the peristaltic pump 5, fan 25, and heating plate 23 are started. The fan 25 blows air into the drying cylinder 3, while the heating plate 23 heats the air to generate low-temperature hot air. After the material enters the drying cylinder 3 through the centrifugal spray head 4, this low-temperature hot air can quickly evaporate the moisture in the material while avoiding damage to heat-sensitive components caused by high temperatures. Because the drying cylinder 3 is in a low-pressure environment, the boiling point of water is significantly reduced, so the moisture in the material can evaporate quickly at a lower temperature, thereby achieving efficient and uniform drying. During the drying process, the vacuum pump 19 can continuously extract air from the drying cylinder 3, and through the cold trap 17, it can effectively adsorb and condense moisture or other harmful components in the gas. During the extraction process, the gas will first pass through the cyclone separator 15. When the gas passes through the cyclone separator 15, the solid material in it will be thrown to the inner wall of the cyclone separator 15 under the action of centrifugal force, and finally deposited in the first collection bottle 21 at the bottom of the cyclone separator 15. After the material is dried, the first collection bottle 21 and the second collection bottle 22 can be removed, and the operator can easily collect and process the dried material.

[0028] In summary, by employing the above-mentioned technical solution of this utility model, and combining the centrifugal spray head 4 with the peristaltic pump 5, it is ensured that the liquid material can be uniformly and stably atomized into tiny droplets, thus improving the drying efficiency. Furthermore, by setting a connecting ring 8 and a threaded rod 12 on one side of the extraction tube 7, the position of the extraction tube 7 can be adjusted. Before placing the placement bucket on the placement plate 27, one end of the extraction tube 7 can be moved away from the placement bucket. After the placement bucket is placed, the extraction tube 7 can be moved downwards, so that one end of the extraction tube 7 contacts the bottom of the bucket. This design not only improves the ease of use of the equipment but also effectively avoids leakage or waste of materials during the extraction process.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
