Description

Technical Field

[0001] This invention relates to a mechanical device for drying and storing proanthocyanidin powder, and particularly to an improved proanthocyanidin powder drying and storage device, belonging to the field of proanthocyanidin processing. Background Technology

[0002] Proanthocyanidins are a general term for a large class of polyphenolic compounds widely found in plants. They are produced by heating in acidic media and are pigment components found in various plant parts, including the skin, shell, seeds, kernels, flowers, and leaves. Grape seeds have the highest content and the most diverse types of proanthocyanidins. Proanthocyanidins have strong antioxidant and free radical scavenging effects, effectively eliminating superoxide anion radicals and hydroxyl radicals. They also participate in the metabolism of phosphoric acid and arachidonic acid, as well as protein phosphorylation, protecting lipids from oxidative damage. Furthermore, they can chelate metal ions to form inert compounds in the body, protecting and stabilizing vitamin C and promoting its absorption and utilization. The specific effects of proanthocyanidins are reflected in the following aspects: (1) improving blood circulation, reducing swelling and bruising, strengthening capillaries, arteries and veins, and improving hypoxia symptoms; (2) treating diabetic retinopathy and improving vision; (3) significantly relieving edema symptoms; (4) protecting the skin and helping to repair skin damage; (5) breaking down and eliminating harmful cholesterol; (6) helping joints, arteries and other tissues maintain normal function; (7) helping to treat allergies, asthma, bronchitis, hay fever, rheumatoid arteritis, sports injuries, stress ulcers and other diseases; (8) relieving and treating varicose veins; (9) helping to improve memory, delay aging, and reduce the risk of stroke; (10) having significant cosmetic effects, improving skin elasticity and healthy circulation, preventing or reducing wrinkles, enhancing whitening, inhibiting the formation of lipofuscin and age spots, promoting skin hydration and smoothness, alleviating the damage of radiation to the skin, and repairing oxidative damage to the skin.

[0003] Currently, proanthocyanidin powder produced using existing processes often contains a large amount of moisture, necessitating timely removal of this moisture and drying. Most existing proanthocyanidin powder drying methods utilize hot airflow to remove moisture, but their effectiveness is limited. Some damp, clumped proanthocyanidin powder is difficult to dry completely under short-term hot airflow. Furthermore, the quality of proanthocyanidin powder dried in a single operation within a confined space is limited, and the processes of adding, removing, and maintaining the powder between drying cycles prevent continuous drying, resulting in low efficiency. Additionally, the confined drying space allows moisture from the gas to be reabsorbed by the proanthocyanidin powder, further affecting the drying effect. In the storage stage, current methods involve manual packaging, handling, and storage, which is time-consuming, labor-intensive, and carries the risk of recontamination, especially since proanthocyanidin powder is easily decomposed and deteriorated by external temperatures. To overcome the shortcomings of existing solutions, it is necessary for those skilled in the art to develop targeted improvements. Summary of the Invention

[0004] This invention discloses a novel solution for drying and storing proanthocyanidin powder. It employs a drying device with crushing and circulating drying functions, combined with a storage device that provides sealed, light-proof, moisture-proof, oxidation-proof, and circulating temperature control functions. The device utilizes a crushing mechanism to break up damp, clumped proanthocyanidin powder, reducing its particle size for easier drying. A circulating drying unit enables closed-loop internal circulation drying of the proanthocyanidin powder. A sealed storage tank provides light-proof, moisture-proof, and oxidation-proof storage. A circulating temperature control unit provides temperature-controlled storage. This solution addresses the problems of existing similar solutions, which cannot effectively dry damp, clumped proanthocyanidin powder, cannot promptly remove moisture generated during drying leading to reabsorption by the powder, affecting drying efficiency, cannot continuously dry proanthocyanidin powder, have low drying efficiency, and rely on manual packaging, handling, and storage of dried proanthocyanidin powder, which is time-consuming, labor-intensive, and carries the risk of re-contamination and oxidation.

[0005] The proanthocyanidin powder drying and storage equipment of the present invention includes a drying device and a storage device. The drying device and the storage device are connected by a conveying connection. The drying device includes a housing, and the housing is equipped with an agglomeration breaking mechanism and a circulating drying unit.

The agglomeration breaking mechanism is used to break up agglomerated proanthocyanidin powder. The circulating drying unit is used to dry the proanthocyanidin powder in real time. The storage device includes a sealed storage box and a circulating temperature control unit. The storage box is equipped with dried proanthocyanidin powder and the circulating temperature control unit is used to control the storage temperature of the proanthocyanidin powder.

[0006] Furthermore, the agglomeration crushing mechanism of this solution includes a crushing roller shaft assembly and a crushing drive unit. The crushing roller shaft assembly is located below the outlet of the feed channel at the top of the equipment housing. The crushing roller shaft assembly includes a male-patterned roller shaft and a female-patterned roller shaft. The male-patterned roller shaft has multiple raised rolling grooves extending axially along the circumferential direction on its rolling surface. The female-patterned roller shaft has multiple recessed rolling grooves extending axially along the circumferential direction on its rolling surface. The core shafts of the male-patterned roller shaft and the female-patterned roller shaft are connected to the crushing drive unit for transmission. During the opposite rotation, the rolling grooves and the oppositely positioned rolling grooves cooperate to rub and crush the agglomerated proanthocyanidin powder.

[0007] Furthermore, the feed channel of this solution has roller mounting grooves on both sides at the lower end of the outlet.

[0008] Furthermore, the circulating drying unit of this solution includes a drying channel extending vertically in a tortuous manner.

[0009] Furthermore, the exhaust vent of this solution is equipped with an exhaust filtration unit, which includes a filter screen and a rotating brush. The filter screen is sealed on the exhaust vent of the dryer, and the rotating brush is located inside the exhaust vent of the dryer on the inner side of the filter screen. The rotating brush includes a brush disc, the central shaft of which is connected to the brush drive unit. The side of the brush disc facing the filter screen is densely covered with brush bristles, which form a sliding and pressing contact connection with the filter screen.

[0010] Furthermore, this solution includes an air intake pump connected to the drying air inlet, which supplies air into the drying channel. An exhaust pump is also installed in the drying air duct connected to the drying exhaust outlet, drawing air from the drying channel. The upper end of the drying channel connects to the lower end of the inclined bottom surface of the feeding chamber. A blowing air inlet is located on the side wall of the feeding chamber at the upper end of the inclined bottom surface, facing the discharge port of the agglomeration and crushing mechanism. The blowing air inlet connects to the dehumidification and filtration unit via a drying air duct within the equipment housing. A blowing pump is installed in the drying air duct connected to the blowing air inlet, blowing air into the discharge port of the agglomeration and crushing mechanism. The total flow rate of the drying air inlet and the blowing air inlet is comparable to the flow rate of the drying exhaust outlet. The buoyancy of the airflow in the drying channel on the proanthocyanidin powder is less than the weight of the proanthocyanidin powder itself.

[0011] Furthermore, the drying channel of this solution includes an upper section, a middle section, and a lower section. The upper section, the middle section, and the lower section are connected end to end to form a zigzag channel. Vibrators are installed in the middle of the bottom surface of the feeding chamber, the upper section, the middle section, and the lower section.

[0012] Furthermore, the circulating temperature control unit of this solution includes a temperature-controlled heat exchange chamber located within the storage tank structure, and multiple vertical temperature-controlled heat exchange tubes located within the storage tank. The top center of the temperature-controlled heat exchange chamber is connected to a temperature-controlled input pipe, and the temperature-controlled input pipe extending downwards out of the storage tank is connected to an external temperature-controlled medium source.

[0013] Furthermore, the top of the storage box in this solution is equipped with a storage inlet pipe with an airtight valve. One side of the storage inlet pipe is equipped with a dehumidification chamber containing a desiccant, and the other side of the storage inlet pipe is equipped with a deoxygenation chamber containing an antioxidant. The dehumidification chamber and the deoxygenation chamber are connected to the internal storage space of the storage box through the storage inlet pipe.

[0014] Furthermore, the storage device in this solution also includes a movable base. The movable base includes a base plate, on which a storage box is mounted.

[0015] This invention relates to a proanthocyanidin powder drying and storage device. It combines a drying unit with crushing and circulating drying functions with a storage unit that features airtight, light-proof, moisture-proof, oxidation-proof, and circulating temperature-controlled functions. This integration of drying and storage functions overcomes the problems of separate drying and storage units, which necessitate manual packaging, handling, and storage of dried proanthocyanidin powder—a time-consuming and labor-intensive process that carries the risk of re-contamination and oxidation. This significantly improves the drying and storage efficiency and effectiveness of proanthocyanidin powder. The device utilizes a crushing mechanism to break up damp, clump-forming proanthocyanidin powder, reducing its particle size and facilitating drying. This overcomes the problem of ineffective drying due to moisture clumping, significantly improving the drying effect. The circulating drying unit achieves closed-loop internal circulation drying of the proanthocyanidin powder, overcoming the problem of moisture generated during drying being reabsorbed by the powder, thus significantly improving the drying efficiency and effectiveness. The agglomeration and crushing mechanism, combined with the circulating drying unit, enables continuous drying of proanthocyanidin powder, overcoming the problem of low drying efficiency caused by the inability to continuously dry proanthocyanidin powder and significantly improving the drying efficiency. The use of a sealed storage box achieves light-proof, moisture-proof, and oxidation-proof storage of proanthocyanidin powder, effectively preventing problems such as light decomposition, moisture absorption, and oxidation-induced deterioration due to improper storage, significantly improving the storage effect of proanthocyanidin powder. The use of a circulating temperature control unit enables temperature-controlled storage of proanthocyanidin powder, effectively preventing decomposition and reaction-induced deterioration due to unsuitable temperatures, significantly improving the storage effect of proanthocyanidin powder. Therefore, this solution solves the problems of existing similar solutions that cannot effectively dry proanthocyanidin powder that has clumped due to moisture, cannot timely remove the moisture generated during drying, causing it to be reabsorbed by the proanthocyanidin powder, affecting the drying effect, cannot continuously dry proanthocyanidin powder, and have lower drying efficiency. It also addresses the problems of manual packaging, handling, and storage of dried proanthocyanidin powder, which is time-consuming and labor-intensive, and carries the risk of re-contamination and oxidation. This solution features significantly improved drying efficiency and effect, and significantly improved preservation and storage effect. Attached Figure Description

Detailed Implementation

[0034] The following is a detailed explanation with reference to the attached diagram.

[0035] like Figure 1 , 2 As shown in Figure 3, the proanthocyanidin powder drying and storage equipment of the present invention includes a drying device 101 and a storage device 102. The drying device 101 and the storage device 102 are connected by a conveying connection. The drying device 101 includes a device housing 200. The device housing 200 is provided with an agglomeration breaking mechanism 300 and a circulating drying unit 400. The agglomeration breaking mechanism 300 is connected by a conveying connection to the circulating drying unit 400. The agglomeration breaking mechanism 300 is used to break up agglomerated proanthocyanidin powder. The circulating drying unit 400 is used to dry the proanthocyanidin powder in real time. The storage device 102 includes a sealed storage box 500 and a circulating temperature control unit 600. The storage box 500 is provided with dried proanthocyanidin powder and the circulating temperature control unit 600 is used to control the storage temperature of the proanthocyanidin powder.

[0036] The above solution employs a drying device 101 with fragmentation and circulating drying functions, combined with a storage device 102 with sealed, light-proof, moisture-proof, oxidation-proof, and circulating temperature-controlled functions. This integrates drying and storage functions. The proanthocyanidin powder requiring drying is fed into the equipment housing 200 through the feed channel 201. A sealed input method can be used to prevent the proanthocyanidin powder from being exposed to light, moisture, oxidation, or other contamination during the input process. After the moisture is removed by the drying device 101, the proanthocyanidin powder is directly discharged from the bottom of the equipment housing 200 into the storage device 102. Similarly, a sealed output method can be used to avoid contamination. When the storage device 102 is full, an empty storage device 102 can be used to continue filling until the requirements are met. This overcomes the problems of time-consuming and labor-intensive manual packaging, handling, and storage of dried proanthocyanidin powder due to separate drying and storage devices, which also carries the risk of re-contamination and oxidation. This significantly improves the drying and storage efficiency and effectiveness of proanthocyanidin powder products.

[0037] This solution utilizes an agglomeration-breaking mechanism 300 to break down damp, agglomerated proanthocyanidin powder, reducing its particle size and facilitating drying. This overcomes the problem of ineffective drying of proanthocyanidin powder due to moisture and agglomeration, significantly improving the drying effect. A circulating drying unit 400 achieves closed-loop internal circulation drying of the proanthocyanidin powder, overcoming the problem of moisture generated during drying being reabsorbed by the powder, thus affecting the drying effect. This significantly improves the efficiency and effectiveness of the drying process. The agglomeration-breaking mechanism 300 and the circulating drying unit 400 work together to continuously dry the proanthocyanidin powder. The broken-down proanthocyanidin powder is discharged as a completely powdered form before entering the drying process. The integrated design of the agglomeration-breaking mechanism 300 and the circulating drying unit 400 overcomes the problem of low drying efficiency due to the inability to continuously dry proanthocyanidin powder, significantly improving the overall drying efficiency. The sealed storage box 500 enables the light-proof, moisture-proof, and oxidation-proof storage of proanthocyanidin powder, effectively preventing problems such as light decomposition, moisture absorption, and oxidation-induced deterioration caused by improper storage. The storage box 500 can be made using existing light-proof and sealing materials, ensuring the realization of basic functions and significantly improving the storage effect of proanthocyanidin powder. The circulating temperature control unit 600 enables temperature-controlled storage of proanthocyanidin powder, achieving cooling or heat preservation through a circulating heat exchange medium. This effectively prevents the decomposition and reaction-induced deterioration of proanthocyanidin powder due to unsuitable temperatures, significantly improving the storage effect of proanthocyanidin powder. Therefore, this solution solves the problems of existing similar solutions that cannot effectively dry proanthocyanidin powder that has clumped due to moisture, cannot timely remove the moisture generated during drying, causing it to be reabsorbed by the proanthocyanidin powder, affecting the drying effect, cannot continuously dry proanthocyanidin powder, and have lower drying efficiency. It also addresses the problems of manual packaging, handling, and storage of dried proanthocyanidin powder, which is time-consuming and labor-intensive, and carries the risk of re-contamination and oxidation. This solution features significantly improved drying efficiency and effect, and significantly improved preservation and storage effect.

[0038] To realize the function of the agglomeration crushing mechanism 300 and improve crushing processing capacity, this solution discloses the specific mechanism settings. For example... Figure 2 , 3As shown in Figure 4, the agglomeration crushing mechanism 300 of this scheme includes a crushing roller shaft assembly and a crushing drive unit 310. The crushing roller shaft assembly is located below the outlet of the feed channel 201 at the top of the equipment housing 200. The crushing roller shaft assembly includes a male-patterned roller shaft 321 and a female-patterned roller shaft 322. The male-patterned roller shaft 321 has multiple raised grinding lines extending axially along the circumferential direction on its rolling surface, and the female-patterned roller shaft 322 has multiple recessed grinding grooves extending axially along the circumferential direction on its rolling surface. The spindles of the male-patterned roller shaft 321 and the female-patterned roller shaft 322 are connected to the crushing drive unit 310 for transmission. During the opposite rotation, the grinding lines and grinding grooves in opposite positions cooperate to rub and crush the agglomerated proanthocyanidin powder. Accordingly, the particle size of proanthocyanidin powder can be controlled by reasonably setting the roller spacing and the size of the grinding lines and grinding grooves.

[0039] Based on the above solutions, to prevent large-particle proanthocyanidin powder that has not undergone crushing and processing from entering the drying process, and to prevent processed proanthocyanidin powder from sticking and accumulating on the roller surface and clogging the mechanism, this solution discloses specific structural settings. For example... Figure 4 , 5 As shown, the feed channel 201 of this scheme has roller mounting grooves 202 on both sides of the lower end outlet. A male roller 321 or a female roller 322 is installed in the roller mounting groove 202. Flexible baffle strips 203 are also provided on both sides of the lower end outlet of the feed channel 201. The baffle strip 203 on one side forms a sliding pressing contact with the roller pressing surface of the male roller 321, and the baffle strip 203 on the other side forms a sliding pressing contact with the roller pressing surface of the female roller 322. The baffle strip 203 blocks the gap between the upper end of the roller mounting groove 202 and the male roller 321 or the female roller 322. The inner side of the lower end of the roller mounting groove 202 is densely covered with bristles 204. The bristles 204 form a sliding pressing contact with the roller pressing surface of the male roller 321 or the female roller 322. The roller mounting groove 202 can be designed as a concave cylindrical surface to facilitate roller installation. When the male roller 321 and female roller 322 rotate in opposite directions, the sliding pressing contact between the baffle edge strip 203 and the roller pressing surface can effectively prevent unprocessed proanthocyanidin powder from entering the drying stage through the gap between the roller mounting groove 202 and the roller. At the same time, the baffle brush 204 can sweep off the proanthocyanidin powder adhering to and accumulated on the roller pressing surface when the roller rotates into the roller mounting groove 202, avoiding the introduction of the powder and causing blockage. This significantly improves the operating efficiency of the agglomeration and crushing mechanism 300 and greatly reduces the failure rate.

[0040] To realize the function of the circulating drying unit 400 and improve the drying effect, this solution discloses a reverse air-drying method that is opposite to the movement direction of the proanthocyanidin powder. For example... Figure 3 , 4As shown, the circulating drying unit 400 of this scheme includes a drying channel 410 extending vertically in a tortuous manner. The upper end of the drying channel 410 is connected to the feeding chamber 420 located below the discharge port of the agglomeration and crushing mechanism 300. The lower end of the drying channel 410 is connected to the discharge port located at the bottom of the equipment housing 200. The lower end of the drying channel 410 is connected to the drying air inlet 431. A drying exhaust port 432 is provided on the side wall of the feeding chamber 420 above the upper end of the drying channel 410. The drying air inlet 431 and the drying exhaust port 432 are connected to the dehumidification filter unit 460 through a drying air passage located in the structure of the equipment housing 200. The dehumidification filter unit 460 is provided with several moisture absorption modules. After being processed by the agglomeration and crushing mechanism 300, the proanthocyanidin powder falls directly into the feeding chamber 420. At this time, the airflow direction of the drying channel 410 is from bottom to top. When the proanthocyanidin powder moves downward through the drying channel 410, it meets the oncoming drying airflow. As the proanthocyanidin powder continues to move downward along the drying channel 410, the moisture in it is also carried away by the continuous drying airflow, thereby achieving the technical purpose of drying. In this process, due to its small particle size, the proanthocyanidin powder is mostly in a dispersed floating and descending state, which is more conducive to the upward airflow carrying away the moisture in it. The moisture in the airflow is absorbed by the moisture absorption module through the circulation process of the dehumidification filter unit 460, thus forming a closed-loop drying airflow. This makes it easier to control the temperature of the drying airflow and avoids the overflow of the drying airflow and proanthocyanidin powder. In the continuous drying process, the drying effect and efficiency are significantly improved.

[0041] Based on the above solution, to prevent floating proanthocyanidin powder from entering the drying air duct and dehumidification filter unit 460 and causing blockage, while also meeting the requirements for smooth airflow during drying, this solution discloses the corresponding mechanism settings. For example... Figure 3 , 4 As shown in Figure 5, the drying exhaust port 432 of this scheme is equipped with an exhaust filter unit 440. The exhaust filter unit 440 includes a filter screen 441 and a rotating brush 442. The filter screen 441 is sealed on the drying exhaust port 432, and the rotating brush 442 is located inside the drying exhaust port 432 on the inner side of the filter screen 441. The rotating brush 442 includes a brush disc, the central shaft of which is connected to the brush drive unit. Brush bristles are densely distributed on the side of the brush disc facing the filter screen 441, and the brush bristles form a sliding and pressing contact connection with the filter screen 441. The operating status of the rotating brush 442 can be set by the control system to clean the proanthocyanidin powder accumulated on the filter screen 441 in real time, ensuring smooth airflow.

[0042] To achieve the required airflow pattern while ensuring efficient transport of proanthocyanidin powder and improving drying results, this solution discloses specific settings. For example... Figure 3 , 4As shown, in this scheme, an air intake pump is installed in the drying air duct connected to the drying air inlet 431, which supplies air into the drying channel 410. An exhaust pump is installed in the drying air duct connected to the drying exhaust outlet 432, which draws air from the drying channel 410. The upper end of the drying channel 410 is connected to the lower end of the inclined bottom surface of the feeding chamber 420. The side wall of the feeding chamber 420 at the upper end of the inclined bottom surface is provided with a blowing air inlet 45 facing the discharge port of the agglomeration and crushing mechanism 300. 1. The blowing air inlet 451 is connected to the dehumidification filter unit 460 through the drying air duct located in the structure of the equipment box 200. A blowing pump is installed in the drying air duct connected to the blowing air inlet 451. The blowing pump blows air to the discharge port of the agglomeration and crushing mechanism 300. The total flow rate of the drying air inlet 431 and the blowing air inlet 451 is equivalent to the flow rate of the drying exhaust port 432. The buoyancy of the airflow in the drying channel 410 on the proanthocyanidin powder is less than the weight of the proanthocyanidin powder itself. The arrangement of the air intake pump and exhaust pump ensures that the airflow in the drying channel 410 flows from bottom to top. The setting of the blowing air inlet 451 and the blowing pump ensures that the proanthocyanidin powder forms a dispersed floating state when it enters the feeding chamber 420, thereby improving the drying effect. At the same time, the airflow direction of the blowing air inlet 451 can also prevent the proanthocyanidin powder from accumulating in the feeding chamber 420, avoiding blockage. The setting of the relevant airflow rate ensures the conveying efficiency of the proanthocyanidin powder and avoids excessive accumulation of proanthocyanidin powder in the drying channel 410.

[0043] To achieve the function of the drying channel 410 and promote the downward movement of proanthocyanidin powder along the drying channel 410, this solution discloses a specific structural configuration. For example... Figure 3 As shown, the drying channel 410 of this scheme includes an upper channel section 411, a middle channel section 412, and a lower channel section 413. The upper channel section 411, the middle channel section 412, and the lower channel section 413 are connected end to end to form a zigzag channel. A vibrator 414 is provided in the middle of the bottom surface of the feeding chamber 420, the upper channel section 411, the middle channel section 412, and the lower channel section 413. The zigzag channel prolongs the contact time between the proanthocyanidin powder and the drying airflow, while the vibrator 414 can promote the downward movement of the proanthocyanidin powder deposited on the bottom surface of the feeding chamber 420, the upper channel section 411, the middle channel section 412, and the lower channel section 413, thereby ensuring the normal conveying process.

[0044] To achieve the function of the circulating temperature control unit 600 and meet the requirement of controlling the storage temperature of proanthocyanidin powder within a reasonable threshold range, this solution discloses the specific structural settings. For example... Figure 3 , 8As shown in Figure 9, the circulating temperature control unit 600 of this scheme includes a temperature-controlled heat exchange chamber 610 located within the housing structure of the storage tank 500, and multiple vertically arranged temperature-controlled heat exchange tubes 620 within the storage tank 500. The top center of the temperature-controlled heat exchange chamber 610 is connected to the temperature-controlled input pipe 630, and the temperature-controlled input pipe 630 extends downward through the storage tank 500 to connect with an external temperature-controlled medium source. The upper end of the temperature-controlled heat exchange tube 620 is connected to the top of the temperature-controlled heat exchange chamber 610, and the lower end of the temperature-controlled heat exchange tube 620 is connected to the bottom of the temperature-controlled heat exchange chamber 610.
