Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of tea pigment drying crystallization, and particularly relates to a tea pigment extraction drying crystallization device. BACKGROUND

[0002] Tea pigments are a class of components extracted from tea leaves and having multiple physiological activities, including theaflavins, thearubigins and theabrownins. They have a wide range of applications in the fields of medicine, health care products, food and the like. For example, tea pigments exhibit good performance in terms of oxidation resistance, blood lipid reduction, antibacterial and the like. In these application scenarios, there are high requirements for the purity and quality of tea pigments.

[0003] Drying crystallization is a key link in the processing of tea pigments. Through drying crystallization, the water in the tea pigment extraction solution can be removed, so that the tea pigments are converted from a liquid state to a solid crystalline state, which is convenient for storage, transportation and subsequent processing and utilization. Moreover, a suitable drying crystallization process can ensure the stability of the chemical structure of tea pigments and prevent adverse chemical reactions such as oxidation, thereby ensuring the quality of tea pigments.

[0004] Traditional drying crystallization equipment has some problems in the processing of tea pigments. After the crystallization of tea pigment solution, there is usually a small amount of water on the surface of the crystals, which can cause the crystals to adhere to each other, thereby affecting the subsequent processing of the crystals.

[0005] Therefore, the utility model provides a tea pigment extraction drying crystallization device. UTILITY MODEL CONTENT

[0008] Preferably, the beating plate is provided with a plurality of circular holes on its surface. This arrangement allows the material to be crushed into smaller and finer pieces, thereby improving the material crushing effect of the beating plate and further reducing the problem of unsatisfactory crystallization due to material agglomeration.

[0009] Preferably, multiple support plates are fixedly connected to the middle of the rotating shaft; rubber scrapers are fixedly connected to the ends of the support plates; and the sidewalls of the rubber scrapers are attached to the inner wall of the material tank. By providing the rubber scrapers in the middle of the rotating shaft, this device can clean the inner wall of the material tank. The rubber scrapers can closely adhere to the inner wall of the material tank, ensuring that there are no blind spots. They can also scrape off materials adhering to the inner wall of the material tank and reduce material residue on the inner wall of the material tank. Because the rubber scrapers are made of rubber, they can reduce scratches on the inner wall of the material tank without affecting their cleaning effect.

[0010] Preferably, a circular plate is provided in the middle of the feed tube; a plurality of feed holes are provided at the top of the circular plate. This arrangement allows for effective dispersion of tea pigment raw materials in various states. If the tea pigment is a liquid extract, the feed holes can evenly spray it throughout the device; if it is solid tea pigment particles, the feed holes allow the particles to fall evenly, ensuring that each particle has ample space for drying and crystallization, thereby improving the efficiency and quality of the drying and crystallization.

[0012] Preferably, the top of the oven is fixed with insulation cotton; the ends of the insulation cotton are fixed to the outer wall of the material tank; and the insulation cotton is wrapped around the middle of the material tank. By providing insulation cotton on the outer wall of the material tank, when the oven dries the interior of the material tank, this arrangement can limit the heat inside the device, reducing the temperature difference between the inside and outside of the device, making the temperature inside the device more stable. The insulation cotton can also reduce the problem that when the material tank is not insulated, the device interior is high temperature and the outside is normal temperature. Frequent temperature changes may cause deformation and cracking of the device shell, thereby affecting the sealing and normal operation of the device.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative characteristics, achieve purpose and effect of the utility model easy to understand, the utility model is further described below in conjunction with specific implementation.

[0024] For example, Figures 1 to 3As shown, a tea pigment extraction, drying and crystallization device described in an embodiment of the present invention includes a heating wire 1; a drying oven 11 is fixedly connected to the top of the heating wire 1; a plurality of air outlet holes 12 are opened on the top of the drying oven 11; a material tank 13 is fixedly connected to the top of the drying oven 11; a rotating shaft 14 is installed on the top of the drying oven 11; the rotating shaft 14 is installed in the middle of the material tank 13; a stirring blade 15 is fixedly connected to the outer wall of the rotating shaft 14; a plurality of square rods 16 are fixedly connected to the middle of the rotating shaft 14; a plurality of the square rods 16 are fixedly connected to the ends of the slapping plates 17; a feed pipe 18 is connected to the middle of the material tank 13; and a motor 19 is installed at the end of the rotating shaft 14. During operation, the extract to be processed is first introduced into the material tank 13 from the feed pipe 18, and then heated by the heating wire 1, and the heat is transmitted to the inside of the material tank 13 through the air outlet 12, and then the motor 19 drives the rotating shaft 14 to rotate at high speed. At this time, the rotating shaft 14 drives the stirring blade 15 and the beating plate 17 to rotate. By providing a beating plate 17 in the middle of the rotating shaft 14, the material entering the material tank 13 can be beaten, and the material can be broken when entering the material tank 13, which can reduce the problem of scaling, wall sticking, etc. that are easy to occur during the drying process, thereby affecting the drying and crystallization effect.

[0025] like Figures 2 to 3 As shown, the surface of the beating plate 17 is provided with a plurality of circular holes 2; the circular holes 2 are provided on the surface of the plurality of beating plates 17. By providing the circular holes 2 on the surface of the beating plate 17, when the beating plate 17 beats the material, the material passes through the middle of the circular holes 2 and enters the interior of the material tank 13. This arrangement can achieve a smaller and finer crushing of the material, thereby improving the crushing effect of the beating plate 17 on the material and further reducing the problem of unsatisfactory crystallization effect caused by material agglomeration.

[0026] like Figure 3 As shown, multiple support plates 3 are fixedly connected to the middle of the rotating shaft 14; rubber scrapers 31 are fixedly connected to the ends of the support plates 3; and the sidewalls of the rubber scrapers 31 are attached to the inner wall of the material tank 13. By providing the rubber scrapers 31 in the middle of the rotating shaft 14, the support plates 3 can drive the rubber scrapers 31 to rotate when the rotating shaft 14 rotates at high speed. At this time, the sidewalls of the rubber scrapers 31 are attached to the inner wall of the material tank 13 and rotate. This device can clean the inner wall of the material tank 13. The rubber scrapers 31 can closely adhere to the inner wall of the material tank 13, ensuring that there are no blind spots when cleaning. They can scrape off material adhering to the inner wall of the material tank 13 and reduce material residue on the inner wall of the material tank 13. Because the rubber scrapers 31 are made of rubber, they can reduce scratches on the inner wall of the material tank 13 without affecting their cleaning effect.

[0027] like Figure 4As shown, a circular plate 4 is positioned in the middle of the feed tube 18; a plurality of feed holes 41 are formed in the top of the circular plate 4. When material enters the inner wall of the material tank 13, the feed holes 41 in the top of the circular plate 4 allow the material to enter the feed tube 18 evenly from the center of the feed holes 41. This arrangement ensures that the feed holes 41 effectively disperse tea pigment raw materials in various states. For solid tea pigment particles, the feed holes 41 ensure an even drop of the particles, ensuring that each particle has ample space for drying and crystallization, thereby improving the efficiency and quality of the drying and crystallization.

[0028] like Figure 4 As shown, a plurality of square slots 5 are provided in the middle of the feed pipe 18; a spring 51 is fixedly connected to the side wall of the square slot 5; the end of the spring 51 is fixedly connected to the circular plate 4; and a vibration motor 52 is installed on the top of the circular plate 4. By providing the vibration motor 52 on the top of the circular plate 4, the vibration of the vibration motor 52 is controlled when the material contacts the surface of the circular plate 4. At this time, the spring 51 fixed to the side wall of the circular plate 4 begins to shake, causing the circular plate 4 to vibrate, and at the same time, the material on the top of the circular plate 4 can be crushed. At this time, the crushed material enters the middle of the feed pipe 18 through the feed hole 41. This setting can achieve a vibration effect on the material. When the tea pigment extract is in a thick paste, it is easy to stick to the top of the circular plate 4 during the feeding process. The vibration motor 52 generates continuous vibration to keep the material in a loose state, so that the material can enter the drying and crystallization device more smoothly.

[0029] like Figure 5 As shown, the top of the drying oven 11 is fixedly connected to thermal insulation 6; the thermal insulation 6 is fixedly connected to the outer wall of the material tank 13; and the thermal insulation 6 is wrapped around the middle of the material tank 13. By providing thermal insulation 6 on the outer wall of the material tank 13, when the drying oven 11 dries the interior of the material tank 13, this arrangement can limit the heat inside the device, reducing the temperature difference between the inside and outside of the device, making the temperature inside the device more stable. The thermal insulation 6 can also reduce the problem that when the material tank 13 is not insulated, the device interior is high temperature and the outside is normal temperature. Frequent temperature changes can cause deformation and cracking of the device shell, thereby affecting the sealing and normal operation of the device.

[0030] Working principle: first, the extract to be processed is introduced into the material tank 13 from the feed pipe 18, and then heated by the heating wire 1, and the heat is transmitted to the material tank 13 through the air outlet 12, and then the motor 19 drives the rotating shaft 14 to rotate at high speed. At this time, the rotating shaft 14 drives the stirring blade 15 and the flapping plate 17 to rotate. A circular hole 2 is opened on the surface of the flapping plate 17. When the flapping plate 17 flaps the material, the material passes through the middle of the circular hole 2 into the material tank 13. A rubber scraper 31 is provided in the middle of the rotating shaft 14. When the rotating shaft 14 rotates at high speed, the rubber scraper 31 can be driven to rotate through the support plate 3. At this time, the side wall of the rubber scraper 31 fits into the inner wall of the material tank 13 and rotates. When the rotating shaft 14 rotates at high speed, the rubber scraper 31 is rotated. When the material enters the inner wall of the material tank 13, a feed hole 41 is provided on the top of the circular plate 4, so that the material can evenly enter the feed pipe 18 from the middle of the feed hole 41. A vibration motor 52 is provided on the top of the circular plate 4, so that when the material contacts the surface of the circular plate 4, the vibration motor 52 is controlled to vibrate. At this time, the spring 51 fixed to the side wall of the circular plate 4 begins to shake, causing the circular plate 4 to vibrate, and at the same time, the material on the top of the circular plate 4 can be crushed. At this time, the crushed material enters the middle of the feed pipe 18 through the feed hole 41. By providing heat preservation cotton 6 on the outer wall of the material tank 13, when the oven 11 dries the inside of the material tank 13, this setting can limit the heat to the inside of the device, reduce the temperature difference between the inside and outside of the device, and make the temperature inside the device more stable.
