Description

Technical Field

[0001] The invention relates to the technical field of glucoraphanin extraction, and in particular to a glucoraphanin extraction device and a technical method. Background Art

[0002] Broccoli is a cruciferous vegetable rich in various nutrients and bioactive substances. Broccoli is a cruciferous vegetable rich in various nutrients and bioactive substances. Among them, glucoraphanin, as an important glucosinolate compound, has many beneficial physiological functions in human health. The extraction and utilization of glucoraphanin in broccoli seeds has become a hot research area. The most common method is to extract glucoraphanin from the water extract of broccoli seeds.

[0003] However, the existing glucoraphanin extraction equipment still has the following problems during use: the cleaned and ground broccoli seeds are added to the extraction tank, water is added in proportion, and the mixture is heated to a certain temperature for hot water extraction. During this operation, working in a fixed mixing mode may cause energy waste and affect the chemical stability of glucoraphanin. When the seed powder is light in weight, it is not necessary to have an excessively high mixing amplitude to achieve full mixing. When the broccoli seed powder is heavy in weight, the stirring amplitude of the mixing structure is appropriately increased to avoid excessive mixing causing energy waste and damage to the extract. By adjusting the mixing float according to the weight of the powder, the mixing structure can consume only the necessary energy, thereby achieving the purpose of energy saving. In addition, more seed powder can be fully contacted with water, ensuring that each seed powder can participate in the extraction process. At the same time, the mixing rod is moved within a suitable range, which helps to maintain the chemical stability of glucoraphanin.

[0004] Therefore, we proposed a glucoraphanin extraction device and technical method to solve the above problems. Summary of the invention

Through the provided adjustment component, after the slider slides down, the fixed cylinder pushes the slider to extend, and the oil in the first oil chamber is injected into the connection between the horizontal plate and the contact plate through the connecting pipe part, and the contact plate slides horizontally to change the extension length, thereby changing the contact position between the oblique edge of the contact plate and the bottom of the slider, thereby changing the downward displacement distance squeezed each time the contact plate passes the bottom of the slider. After the extension length of the slider changes, the downward displacement distance squeezed by the slider and the contact plate will change, and the downward displacement length of the horizontal plate in the vertical groove will change synchronously; By setting the amplitude adjustment component, after the horizontal plate slides downward, the initial opening and closing angle of each group of mixing rods is changed. According to different amounts of powder, the mixing amplitude of the mixing rods during the later operation is changed, and the swing amplitude and range of the mixing rods are adjusted accordingly. Therefore, during the extraction process, different amounts of powder are put in and the corresponding mixing components are adjusted. It can also make more seed powder fully contact with water, ensuring that every seed powder can participate in the extraction process. The mixing rods move within a suitable range, which helps to maintain the chemical stability of glucoraphanin. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1 - Fig.11As shown, the present invention provides a technical solution: a glucoraphanin extraction device, comprising a mounting frame 1, and an extraction tank 2 is mounted on the mounting frame 1, and a heating layer is arranged on the inner wall of the extraction tank 2, and a sealing cover 3 is connected to the top of the extraction tank 2, and an ultrasonic generator 4 is symmetrically installed in the middle of the outer side of the extraction tank 2, a motor 5 is installed on the inner top of the sealing cover 3, and the output end of the motor 5 is connected to a driving gear 6, and the outer side of the driving gear 6 is meshingly connected with a driven gear 7, and a shaft rod 8 is integrally installed at the bottom of the driven gear 7, and the shaft rod 8 extends to the inner bottom of the extraction tank 2, and the outer side of the shaft rod 8 is provided with mixing rods 9 in groups at equal angles, and the outer side of the mixing rod 9 is provided with guide plates 10 at equal intervals; An extraction device is used in the process of extracting the extractor. First, the basic components of the extraction device are introduced. The mounting frame 1 is used to install the extraction tank 2. The sealing cover 3 on the top of the extraction tank 2 is provided with a material delivery port. The washed, dried and ground broccoli seed powder is placed in the extraction tank 2 through the delivery port. Water is then injected according to a corresponding proportion. Then the motor 5 and the ultrasonic generator 4 inside the sealing cover 3 are started, and the driving gear 6 is meshed with the driven gear 7, thereby driving the shaft 8 to rotate. After the shaft 8 rotates, the external mixing rod 9 is driven to rotate synchronously in a circumferential direction. The mixing rod 9 also opens and closes when rotating in a circumferential direction, thereby increasing the mixing mode, so that the powder and water are mixed and contacted more fully. At the same time, the guide plate 10 provided on the mixing rod 9 can reduce the water flow resistance during the circumferential rotation. Embodiment 1: In the process of using the existing device for extracting glucoraphanin from broccoli seed water extract, the mixing component is usually set to a fixed activity mode. When the amount of broccoli powder added is different, it is not convenient to adjust in time, which may cause unnecessary energy loss and affect the stability of glucoraphanin. Therefore, the following solution is proposed. Please refer to Figure 6 and Fig.10 As shown; The inner upper part of the extraction tank 2 is provided with a carrier plate 11, and the carrier plate 11 is sleeved on the outer side of the shaft 8, and the bottom of the carrier plate 11 is slidably connected with a fan-shaped plate 12 at equal angles, and the carrier plate 11 and the fan-shaped plate 12 are evenly spaced with through holes, and also include: a carrier component 13, the carrier component 13 is arranged on the outer side of the shaft 8 and between the carrier plate 11 and the fan-shaped plate 12, and the carrier component 13 pre-adjusts the use state of the outer mechanism at the top of the shaft 8 according to the weight of the broccoli powder, and the carrier component 13 includes a slider 131, and the slider 131 is symmetrically fixed on the middle inner wall of the carrier plate 11, and the slider 131 is slidably connected to the slide groove 132, and the slide groove 132 is symmetrically opened on the outer side of the shaft 8; When in use, after the broccoli seed powder is placed inside the extraction tank 2, it falls on the top of the carrier plate 11. The carrier plate 11 is pressed by gravity and drives the slider 131 to slide down in the slide groove 132. The sliding of the carrier plate 11 drives the fan-shaped plate 12 at the bottom to move downward synchronously. There are four fan-shaped plates 12 below the carrier plate 11, and a protrusion 133 is fixed integrally on the top of the fan-shaped plate 12, and the protrusion 133 is slidably connected to the bottom of the carrier plate 11 through a spring 134, and a magnetic block is arranged on the inner wall of the fan-shaped plate 12 close to the shaft 8, and a bar-shaped electromagnet 135 is integrally arranged on the outer side of the shaft 8; After the powder is added, the downward position of the fan-shaped plate 12 will stop. At this time, the electromagnet 135 on the shaft 8 is energized. Due to the magnetic force, the fan-shaped plate 12 gathers toward the center, and then fits and adsorbs on the outer side of the shaft 8, thereby fixing the downward position of the supporting plate 11 and the fan-shaped plate 12. When the fan-shaped plate 12 gathers, it drives the protrusion 133 to compress the spring 134 to slide on the bottom of the supporting plate 11. After the fan-shaped plate 12 gathers, the through hole on the fan-shaped plate 12 coincides with the through hole on the supporting plate 11, and the broccoli powder falls from the through hole. The subsequent injection of water flushes the powder into the interior of the extraction tank 2, thereby providing an adjustment basis for the subsequent adjustment of the corresponding components.

[0023] Embodiment 2: When mixing powders of different weights and water, the mixing range of the mixing component is adjusted to adapt to different usage conditions. Therefore, the following solution is proposed. Please refer to Figure 4 - Fig.10 As shown; An adjusting component 14, which is arranged on the top outer side of the shaft rod 8, and the adjusting component 14 adjusts the initial opening and closing angle of the mixing rod 9 according to the weight of the broccoli powder added, and the adjusting component 14 includes a first piston plate 141 fixed to the bottom of the slider 131, and the bottom of the first piston plate 141 is slidably connected to the top of the first oil chamber 142, and the first oil chamber 142 is opened inside the shaft rod 8, and the first oil chamber 142 is connected to the fixing cylinder 144 at the bottom of the ring 143 through a connecting pipe, and the ring 143 is installed on the top inner wall of the sealing cover 3, the ring 143 is sleeved on the top outer side of the shaft rod 8, and the fixing cylinder 144 is installed at an equal angle to the bottom of the ring 143, and the bottom of the fixing cylinder 144 is slidably connected to the sliding rod 145, and the bottom of the sliding rod 145 is set as a spherical structure; When in use, for different amounts of powder, the slider 131 slides down in the slide groove 132 to squeeze the first piston plate 141, and the first piston plate 141 moves down in the first oil chamber 142, thereby squeezing out the oil in the first oil chamber 142 and injecting it into the interior of the fixed cylinder 144 at the bottom of the ring 143 through the connecting pipe part. When the oil in the fixed cylinder 144 increases, the slide rod 145 is pushed out; A vertical groove 147 is symmetrically provided on the outer side of the top of the shaft 8, and a horizontal plate 146 is slidably connected in the vertical groove 147, and a contact plate 148 is slidably connected to the outer side of the horizontal plate 146, and the interior of the horizontal plate 146 is connected to the first oil chamber 142 through a connecting pipe, and the contact plate 148 is set to a right-angle trapezoidal structure, and the hypotenuse of the contact plate 148 intermittently squeezes and contacts with the bottom of the sliding rod 145 after the shaft 8 rotates; When in use, the oil inside the first oil chamber 142 is injected into the connection between the cross plate 146 and the resistance plate 148 through the connecting pipe part, so that the resistance plate 148 can slide horizontally and change the extension length. After the extension length is changed, the contact position between the hypotenuse of the resistance plate 148 and the bottom of the slide bar 145 can be changed. After the position is changed, the downward distance that the resistance plate 148 is squeezed each time it passes the bottom of the slide bar 145 can be changed. After the extension length of the slide bar 145 is changed, when the shaft rod 8 drives the cross plate 146 and the resistance plate 148 to rotate, the downward distance squeezed and moved by the slide bar 145 and the resistance plate 148 will change, and the downward length of the cross plate 146 in the vertical groove 147 will change synchronously.

[0024] Embodiment 3: In order to further adapt to the change in powder weight and maintain good chemical stability of glucoraphanin, the mixing rod 9 is moved within a suitable range so that the seed powder is fully in contact with water and every grain of seed powder can participate in the extraction process. Therefore, the following scheme is proposed. Please refer to Figure 4 - Figure 6 , Figure 8 and Fig.11 As shown; Amplitude adjustment component 15, the amplitude adjustment component 15 is arranged between the inner side of the top of the shaft rod 8 and the mixing rod 9, and the amplitude adjustment component 15 adjusts the mixing amplitude of the mixing rod 9 according to the weight of the broccoli powder, the amplitude adjustment component 15 includes a second piston plate 151 fixedly connected to the bottom of the cross plate 146, and the second piston plate 151 is arranged in a "U" shape structure, and the bottom of the second piston plate 151 is slidably connected to the second oil chamber 152, and the second oil chamber 152 is opened inside the shaft rod 8; When in use, the horizontal plate 146 slides downward to drive the second piston plate 151 at the bottom to move downward in the second oil chamber 152, and the second oil chamber 152 injects oil into the interior of the sliding sleeve 153 through the connecting pipe, thereby changing the initial opening and closing angle of each group of mixing rods 9; The second oil chamber 152 is connected to the interior of the sliding sleeve 153 through a connecting pipe, and the sliding sleeve 153 is arranged in the middle of each group of mixing rods 9, and the upper and lower sides of the sliding sleeve 153 are slidably connected with an arc plate 154, and the outer side of the arc plate 154 is fixedly connected to the mixing rod 9, and a torsion spring is installed at the hinge of the mixing rod 9 and the shaft rod 8; When in use, after the sliding sleeve 153 is injected with oil, the arc plates 154 on the upper and lower sides are pushed out, thereby pushing the mixing rod 9 to rotate. According to different amounts of powder, the mixing amplitude of the mixing rod 9 during the later operation is changed. Every time the shaft rod 8 drives the contact plate 148 to pass through the bottom of the sliding rod 145, the squeezed oil will be injected into the sliding sleeve 153, so that the arc plate 154 drives the mixing rod 9 to swing, and the swing amplitude and range of the mixing rod 9 will be adjusted accordingly. Therefore, during the extraction process, different amounts of powder are put in and the corresponding mixing components are adjusted, so that the mixing structure consumes only necessary energy, achieving the purpose of energy saving, and can also make more seed powder fully contact with water, ensuring that each seed powder can participate in the extraction process. The mixing rod 9 moves within a suitable range, which helps to maintain the chemical stability of glucoraphanin.

[0025] refer to Figure 1 As shown, a glucoraphanin extraction method comprises the following steps: S1. Preprocessing: Select high-quality, plump, and pest-free broccoli seeds as raw materials, and rinse the screened broccoli seeds with clean water; The selected broccoli seeds are dried in an oven at 40-60°C to a constant weight, and the dried seeds are crushed into 20-60 mesh powder using a crusher for later use; S2. Extraction operation: Add the crushed broccoli seed powder into the extraction device, add deionized water according to the solid-liquid ratio of 1:5-1:20 (g / ml), turn on the heating at the same time, heat the extract to 100°C, and perform hot water extraction for 30-120 minutes. During the extraction process, start the extraction device and set the mixing speed to 100-300 rpm to ensure that the seed powder is fully in contact with the water; In order to further improve the extraction efficiency, ultrasonic-assisted extraction equipment is used in addition to hot water extraction. Ultrasonic action can produce a cavitation effect, which ruptures plant cells, making it easier for glucoraphanin to be released from cells into the extraction solvent. S3, filtration, concentration and purification: After the extraction is completed, the solid residue in the extract is removed by filtering; The filtered extract is concentrated by a reduced pressure concentration method; Select a silica gel column or a macroporous adsorption resin column to purify the concentrated extract by column chromatography.
