Technical Field
[0001] This utility model belongs to the technical field of freeze-dried powder production equipment, specifically, it relates to a preparation device for freeze-dried black goji berry anthocyanin powder. Background Technology
[0002] Anthocyanins, as natural water-soluble pigments, are widely distributed in the plant kingdom, especially in black goji berries, where the anthocyanin content is several times higher than in conventional foods. This natural pigment not only gives plants vibrant colors but also possesses multiple biological activities: its anti-radiation and antioxidant properties can build a protective barrier against ultraviolet radiation on the skin and improve visual function by stabilizing vitamin A in the retina; at the circulatory system level, anthocyanins inhibit the process of atherosclerosis by scavenging free radicals, significantly reducing the risk of cardiovascular and cerebrovascular complications; in the nervous system, its sedative and calming effects have a clear effect on improving neurasthenia. Most importantly, anthocyanins from black goji berries exhibit unique anti-tumor activity, achieving anti-cancer intervention through inducing apoptosis in cancer cells, forming a cross-domain application value from daily health care to disease prevention and treatment.
[0003] In the preparation of freeze-dried black goji berry anthocyanin powder, traditional extraction processes face three major technical bottlenecks: simple soaking extraction relies on a slow molecular diffusion process, resulting in an extraction cycle of several hours; conventional stirring extraction, while enhancing mass transfer, cannot achieve cell wall disruption, limiting the release efficiency of active ingredients; and liquid-solid separation extraction requires additional filtration devices, which can easily cause process interruptions; all of these factors severely affect the preparation efficiency of freeze-dried black goji berry anthocyanin powder.
[0004] Based on this, the present invention provides a preparation device for freeze-dried black goji berry anthocyanin powder to solve the problems existing in the prior art. Utility Model Content
[0005] In view of this, the main purpose of this utility model is to provide a preparation device for freeze-dried black goji berry anthocyanin powder, so as to solve the problems of long extraction cycle, low release efficiency of effective ingredients and easy process interruption of traditional preparation equipment.
[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0007] An apparatus for preparing freeze-dried anthocyanin powder from black goji berries includes a reaction vessel with a lid at the upper opening. A pressurized reaction chamber is formed inside the reaction vessel. A porous filter cartridge is coaxially arranged inside the reaction chamber, dividing the internal space into an extraction chamber and a precipitation chamber. A raw material addition pipe is provided at the upper end of the extraction chamber, and a slag discharge pipe is provided at the lower end. A stirring and crushing mechanism is also provided inside the extraction chamber. The precipitation chamber is located outside the extraction chamber, and a liquid addition pipe is provided at the upper end of the precipitation chamber, and a liquid discharge pipe is provided at the lower end.
[0008] In a preferred embodiment, both the liquid addition pipe and the raw material addition pipe are mounted on the tank cover and extend through the tank cover, with the end of the raw material addition pipe extending into the filter cartridge.
[0009] In a preferred embodiment, the drain pipe is located on the lower side wall of the reaction vessel and is higher than the bottom of the reaction vessel.
[0010] In a preferred embodiment, the slag discharge pipe is disposed on the base of the reaction vessel and matches the outlet of the conical collection hopper at the lower end of the filter cartridge.
[0011] In a preferred embodiment, the side wall of the reaction vessel is also provided with several observation ports.
[0012] In a preferred embodiment, the filter cartridge is fixed inside the reaction vessel by a fixed sleeve, and the fixed sleeve is provided with several flow guide holes.
[0013] In a preferred embodiment, the stirring and crushing mechanism includes a drive motor, which is located on the outside of the tank cover, and the drive end of the drive motor is connected to the stirring rod via a key shaft. The stirring rod is provided with several blades via bushings.
[0014] In a preferred embodiment, the blade is further provided with a plurality of trapezoidal breaking teeth, which are arranged radially in an Archimedean spiral pattern on the blade.
[0015] In a preferred embodiment, an ultrasonic transducer is further provided at the lower end of the stirring rod.
[0016] In a preferred embodiment, the tank cover is disposed at the upper opening of the reaction vessel via a flange sealing structure.
[0017] Compared with the prior art, this utility model provides a device for preparing freeze-dried black goji berry anthocyanin powder, which has the following beneficial effects:
[0018] 1. By setting up a stirring and crushing mechanism, high-frequency shearing crushing can be implemented during the crushing and extraction stage. The trapezoidal crushing teeth mechanically stir and cut the material at a set speed. Simultaneously, the ultrasonic transducer generates a cavitation effect, realizing the synergistic effect of physical cell wall disruption and chemical dissolution of black goji berry material in the extraction chamber, effectively improving the release efficiency of anthocyanins.
[0019] 2. By incorporating a filter cartridge, the crushed slurry undergoes primary separation under negative pressure during the solid-liquid separation stage. Larger particles are retained in the extraction chamber, while the anthocyanin solution enters the precipitation chamber for secondary clarification. This integrated crushing-extraction-separation design shortens the processing time per batch and effectively improves the anthocyanin yield. It solves the problems of long extraction cycles, low effective component release efficiency, and susceptibility to process interruptions inherent in traditional preparation equipment.

[0028] The structure of the apparatus for preparing freeze-dried black goji berry anthocyanin powder will be further described in detail below with reference to the accompanying drawings and embodiments of the present invention.
[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments as described in this application.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0033] As per the instruction manual Figures 1-5 As shown, this utility model provides a technical solution:
[0034] A device for preparing freeze-dried anthocyanin powder from black goji berries is used for rapid leaching and extraction of anthocyanins during the preparation of freeze-dried anthocyanin powder. The device includes a reaction tank 1, with a removable tank cover 2 installed at the upper opening of the reaction tank 1 via a flange sealing structure. A pressure-bearing reaction chamber is formed inside the reaction tank 1. A porous filter cartridge 11 is coaxially installed inside the reaction chamber, dividing the internal space into two functional areas: the inner area is the extraction chamber with a stirring and crushing mechanism, equipped with a raw material adding pipe 8 at the upper end for directional feeding of black goji berry raw materials, and a slag discharge pipe 3 at the lower end to discharge the extracted black goji berry residue. The stirring and crushing mechanism is located inside the extraction chamber and connected to the tank cover 2; the outer area is the sedimentation and liquid discharge chamber, with an extraction solvent injected at the upper end via a liquid adding pipe 6, and a drain pipe 7 integrated at the bottom connected to a vacuum filtration system to discharge the extract.
[0035] As described above, this device incorporates three core technical components during operation: The crushing and extraction stage involves high-frequency shearing crushing via a stirring and crushing mechanism. Trapezoidal crushing teeth 16 on the surface of the paddle 15 mechanically stir and cut the material at a set speed, simultaneously coordinating with the ultrasonic transducer 13 to generate cavitation, achieving a synergistic effect of physical cell wall disruption and chemical dissolution of the black goji berry material within the extraction chamber, thus increasing anthocyanin release efficiency by more than three times. The solid-liquid separation stage involves primary separation of the crushed slurry through the filter cylinder 11 under negative pressure. Large-particle residues are retained in the extraction chamber, while the anthocyanin solution enters the precipitation chamber for secondary clarification. The continuous drainage stage involves automatically activating a diaphragm pump when the liquid level in the precipitation chamber reaches a set value, transporting the material to the next process via the drainage pipe 7. Residual residues are discharged through the slag discharge pipe 3. This device, through its integrated crushing-extraction-separation design, shortens the processing time per batch and effectively improves the anthocyanin yield.
[0036] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the filter cartridge 11 is made of 316L stainless steel sintered felt with a pore size range of 20-50μm, combining mechanical strength with micron-level solid-liquid separation accuracy.
[0037] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, both the liquid addition pipe 6 and the raw material addition pipe 8 are mounted on the tank cover 2 and extend through it. The end of the raw material addition pipe 8 extends into the filter cartridge 11 for adding black goji berry material into the filter cartridge 11. The outer ends of both the liquid addition pipe 6 and the raw material addition pipe 8 are connected to the feeding pipe via flange structures, allowing for feeding and injecting of extraction solvent into the reaction tank 1 using the liquid addition pipe 6 and the raw material addition pipe 8 respectively after use and installation.
[0038] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the drain pipe 7 is located on the lower side wall of the reaction tank 1, and is higher than the bottom of the reaction tank 1. A natural settling zone is formed by the liquid level difference, allowing the heavier black goji berry residue to settle under gravity in the conical hopper at the bottom of the filter cartridge 11. The clarified liquid phase is continuously discharged through the drain pipe 7, achieving coordinated operation of dynamic filtration and continuous drainage. The slag discharge pipe 3 is located on the base 4 of the reaction tank 1 and is perfectly matched with the outlet of the conical hopper at the lower end of the filter cartridge 11, forming a stepless transition structure. When slag discharge is performed, the slag discharge pipe 3 is opened, and the sediment is completely discharged under the guidance of gravity and the conical structure.
[0039] It should be noted that control valves are installed on the slag discharge pipe 3, liquid addition pipe 6, liquid discharge pipe 7, and raw material addition pipe 8. These control valves are used to control the opening and closing of the slag discharge pipe 3, liquid addition pipe 6, liquid discharge pipe 7, and raw material addition pipe 8 during use, facilitating automated feeding and discharging. The control valves are well-known technology to those skilled in the art and will not be described in detail here.
[0040] In a preferred embodiment, such as Figure 1 As shown, the side wall of the reaction vessel 1 is also provided with several observation ports 12, which facilitates workers to observe the condition inside the vessel during use.
[0041] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the filter cartridge 11 is fixedly installed inside the reaction vessel 1 by a fixed sleeve 10, and a plurality of flow guide holes 17 are provided on the fixed sleeve 10, through which the liquid on the upper and lower sides of the fixed sleeve 10 can flow.
[0042] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the stirring and crushing mechanism includes a drive motor 5, which is fixedly installed on the outside of the tank cover 2. The drive end of the drive motor 5 is connected to the stirring rod 14 via a key shaft 9. Several blades 15 are fixedly installed on the stirring rod 14 via bushings, with each group of blades evenly distributed radially at 120°. In use, the drive motor 5 drives the stirring rod 14 to rotate, which in turn drives the blades 15 to stir the black goji berries in the extraction chamber, thereby improving the anthocyanin extraction efficiency.
[0043] In a preferred embodiment, such as Figure 4 and Figure 5As shown, the blade 15 is also provided with several trapezoidal breaking teeth 16, which are arranged radially in an Archimedean spiral pattern on the blade 15. In use, the arrangement of the breaking teeth 16 can create a turbulent flow field, which, combined with the linear velocity at the end of the blade 15, can achieve synergistic enhancement of mechanical cell wall disruption and solute diffusion in black goji berry, thereby improving the extraction efficiency of anthocyanins.
[0044] It should be noted that the surface of the crushing tooth 16 is coated with a polytetrafluoroethylene anti-stick layer, which can effectively prevent wet materials from adhering.
[0045] In a preferred embodiment, such as Figure 4 and Figure 5 As shown, an ultrasonic transducer 13 is also provided at the lower end of the stirring rod 14. During the stirring and extraction process, the ultrasonic transducer 13 generates a cavitation effect to achieve a synergistic effect of physical cell wall disruption and chemical dissolution, thereby improving the extraction efficiency of anthocyanins.
[0046] The usage process and operating principle of the apparatus for preparing black goji berry anthocyanin freeze-dried powder according to this utility model include:
[0047] Step 1: Feeding stage;
[0048] Black goji berry powder is added quantitatively through raw material addition pipe 8, and a vacuum pump is simultaneously started to draw the pressure in the reaction chamber to -0.08MPa, creating a negative pressure feeding environment;
[0049] Step 2: Crushing and extraction;
[0050] Injecting the extract: Inject 5 times the volume of 40% ethanol solution into the sedimentation chamber through the liquid addition pipe 6. Once the liquid level reaches the set value, the control valve will automatically close after triggering.
[0051] Start the crushing program: drive motor 5 to rotate, simultaneously turn on ultrasonic transducer 13, and set the processing time to 45 minutes;
[0052] Real-time monitoring: The crushing status can be observed through the tank sight glass. When the torque sensor shows a sudden drop of 15% in load, the system automatically switches to low-speed maintenance mode (800 rpm).
[0053] Step 3: Solid-liquid separation;
[0054] Primary separation: The crushed slurry passes through the filter cylinder 11 under negative pressure to complete solid phase retention, and the filtrate enters the sedimentation chamber for secondary clarification;
[0055] Dynamic sedimentation: After the liquid in the sedimentation chamber has clarified, it is continuously discharged through the high-level drainage pipe 7;
[0056] Step 4: Slag removal and cleaning;
[0057] Residue discharge: Open the control valve, and the residue will be discharged through the slag discharge pipe 3 under the guidance of gravity and the conical structure;
[0058] Step 5: Pretreatment before freeze-drying;
[0059] The collected clarified liquid was sterilized by passing it through a 0.22μm pleated filter, concentrated under vacuum to a Brix value of 25%, and then entered a freeze dryer. After pre-freezing at -40℃ for 4 hours, it underwent vacuum sublimation drying for 48 hours.
[0060] It should be noted that the aforementioned drive motor 5 and ultrasonic transducer 13 are all devices with relatively mature existing technology. The specific models and power supply methods can be selected according to actual needs, and will not be elaborated here.
[0061] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
