Description

Technical Field

[0001] The invention relates to the technical field of crocin extraction, and in particular to a crocin extraction mechanism in flowers and fruits. Background Art

[0002] Crocin is a precious water-soluble carotenoid with high medicinal value. Taking advantage of the water-soluble characteristics of crocin, the traditional method of extracting crocin is to soak the treated raw materials in water and then concentrate the crocin by evaporation. In order to avoid the loss of crocin caused by high-temperature concentration, a reduced pressure steam reactor is generally used to concentrate the solution.

[0003] During actual operation, steam droplets will be generated on the inner wall of the top cover of the reduced pressure steam reactor. When too many droplets gather, they will drip into the solution in the reactor, thereby reducing the concentration efficiency. The reactor body and the top cover are usually sealed with a rubber sealing ring. High temperature will cause the rubber sealing ring to age faster, resulting in reduced sealing of the reactor. Reduced sealing will further lead to an increase in steam condensation droplets inside the reactor body, thereby affecting the concentration efficiency. Therefore, the present application provides a crocin extraction mechanism in flowers and fruits to meet the needs. Summary of the invention

The top cover 2 is composed of an arc-shaped dome and a horizontal bottom edge. The bottom edge of the top cover 2 is a flange structure and is adapted to the first flange plate 17. A guide groove 12 is provided on the inner wall of the top cover 2. The guide groove 12 is located at the junction of the dome and the bottom edge. The cross-section of the guide groove 12 is an inverted J-shaped structure. The downwardly protruding portion of the guide groove 12 can be used to gather water flow, thereby guiding the direction of the water flow, so that the water flow on the inner wall of the top cover 2 can be gathered into strands faster and drip quickly for easy collection. A plurality of sets of pipe connectors for connecting pipes are also provided on the top cover 2. In order to facilitate maintenance, an inspection port is also provided on the top cover 2.

[0040] like Figures 2 to 8 As shown, the steam recovery mechanism 4 also includes a first sealing groove 13 opened on the top of the first flange plate 17. The first sealing groove 13 corresponds to the position of the guide groove 12. The guide groove 12 guides the water flow on the inner wall of the top cover 2 to quickly enter the first sealing groove 13. When the first sealing groove 13 is filled with water, the surface tension of the water is used to form a sealing film at the connection gap between the kettle body 1 and the top cover 2, thereby increasing the sealing performance of the device, reducing the influence of the external temperature on the internal temperature of the kettle body 1, and then reducing the temperature fluctuation inside the kettle body 1, and reducing the generation of steam water droplets. The first sealing groove 13 is an annular structure, and the top of the first flange plate 17 is also opened A drainage groove 14 is provided, which is a linear structure and intersects with the first sealing groove 13. One end of the drainage groove 14 away from the first sealing groove 13 is closed, and a discharge port 15 is provided at the bottom of the closed end of the drainage groove 14. The discharge port 15 penetrates the first flange plate 17, and an embedding groove 18 is provided at the bottom of the first flange plate 17. The embedding groove 18 is coaxially arranged with the discharge port 15, and a matching protrusion 19 is fixedly connected to the bottom of the embedding groove 18. By providing the drainage groove 14 and the embedding groove 18, the water flow entering the first sealing groove 13 is discharged in time, thereby preventing excessive water in the first sealing groove 13 from overflowing and re-entering the interior of the kettle body 1 to affect the concentration efficiency.

[0041] The steam recovery mechanism 4 also includes a recovery bottle 16 installed on the first flange plate 17, a second flange plate 20 is fixedly connected to the top of the recovery bottle 16, the second flange plate 20 is adapted to the embedding groove 18, a matching groove 21 is provided on the top of the second flange plate 20, the matching groove 21 is adapted to the matching protrusion 19, by setting the recovery bottle 16, when in use, the second flange plate 20 is embedded in the embedding groove 18, by pressing the recovery bottle 16, the matching protrusion 19 is forced to embed in the matching groove 21 and form an interference fit, so that the recovery bottle 16 is clamped with the first flange plate 17, and the wiper assembly 11 includes The stirring mechanism 3 is connected to a connecting sleeve 22, and a scraper 23 is fixedly connected to one side of the connecting sleeve 22. The scraper 23 is an arc-shaped structure as a whole and is in close contact with the inner wall of the top cover 2. The cross section of the scraper 23 includes an open circular ring, and an elongated S-shaped wiper portion 27 is fixedly connected to one side of the open end of the circular ring. The wiper portion 27 is smoothly connected to the water guide portion 26. The wiper portion 27 is an elastic structure. By setting the wiper assembly 11, when in use, the end of the wiper portion 27 away from the water guide portion 26 is in close contact with the inner wall of the top cover 2, and the stirring mechanism 3 drives the wiper assembly 11 to rotate, so that the wiper portion 27 continuously scrapes the inner wall of the top cover 2 in a circular motion.

[0042] like Figure 2 , Fig. 9 and Fig.10As shown, the connecting sleeve 22 is a straight cylinder structure, and the inner wall of the connecting sleeve 22 is fixedly connected with multiple groups of anti-skid strips 24, and the multiple groups of anti-skid strips 24 are evenly distributed. The anti-skid strips 24 can be made of rubber material, which can increase the friction between the connecting sleeve 22 and the stirring mechanism 3, thereby enhancing the cooperation between the anti-skid strips 24 and the stirring mechanism 3. The side wall of the anti-skid strip 24 is provided with a spiral groove 25, and the spiral groove 25 is a spiral structure. The spiral groove 25 makes the lower end of the connecting sleeve 22 have a certain elasticity. When the wiper assembly 11 is connected to the stirring mechanism 3, the spiral groove 25 can provide a certain pre-tightening force, so that the wiper assembly 11 and the stirring mechanism 3 and the top cover 2 are more closely matched, which can reduce the impact of vibration on the connection and reduce noise. The stirring mechanism 3 includes a support frame 6 fixedly connected to the top of the top cover 2, and the top of the support frame 6 is fixedly connected to a motor 5, and the motor 5 includes The motor body and the reducer used in conjunction with the motor, the motor 5 is equipped with an output shaft 7 through a coupling 8. The specific output shaft 7 should be connected to the output shaft of the reducer through the coupling 8, and the output shaft 7 extends through the support frame 6 to the inside of the top cover 2, and the output shaft 7 is connected to the stirring rod 9 through another set of couplings 8. The output shaft 7 is fixedly connected to a limiting abutment plate 10, and a connecting sleeve 22 is sleeved on the output shaft 7 and abuts against the limiting abutment plate 10. After the connecting sleeve 22 is sleeved on the output shaft 7, the anti-slip strip 24 will be squeezed to a certain extent, so that the output shaft 7 is in close contact with the anti-slip strip 24, thereby greatly increasing the friction between the connecting sleeve 22 and the output shaft 7, so that the output shaft 7 can carry the connecting sleeve 22 to rotate synchronously, and the output shaft 7 and the stirring rod 9 adopt a segmented structure, which can be conveniently coordinated with the steam recovery mechanism 4, and is convenient for the installation and disassembly of the wiper assembly 11.

[0043] The working principle provided by the present invention is that when in use, the support frame 6 is first fixedly connected to the top of the top cover 2, and then the motor 5 is installed on the top of the support frame 6, and then the connecting sleeve 22 is sleeved on the output shaft 7, and then the output shaft 7 is connected to the output shaft of the motor 5 through a set of couplings 8. After the connection between the connecting sleeve 22 and the output shaft 7 is completed, the bottom of the connecting sleeve 22 will abut against the limiting abutment 10, and the top cover 2 and the limiting abutment 10 cooperate to apply a certain clamping force to the connecting sleeve 22, and a certain deformation will occur at the spiral groove 25 to provide a pre-tightening force, so that the wiper part 27 is tightly attached to the inner wall of the top cover 2 or even produces a certain deformation, the top cover 2 is fixedly installed on the kettle body 1 by bolts, and after completing other connections of the device, the device is tested. After the test is completed, the device is started to start the concentration reaction.

[0044] After the stirring mechanism 3 is started, the motor 5 drives the output shaft 7 to rotate, and the output shaft 7 drives the wiper assembly 11 to rotate synchronously. During the rotation of the wiper assembly 11, the wiper portion 27 continuously scrapes the inner wall of the top cover 2 to gather the water droplets condensed on the inner wall of the top cover 2. When the water droplets gather into a small flowable water flow, the small water flow first enters the water guide portion 26 along the side wall of the wiper portion 27, and slides down into the first sealing groove 13 along the inner wall of the water guide portion 26. The water flow on the inner wall of the top cover 2 that has not completely entered the water guide portion 26 will slide down into the guide groove 12 along the inner wall of the top cover 2, and finally enter the first sealing groove 13 along the guidance of the inner wall of the guide groove 12. The large water flow gathered in the first sealing groove 13 fills the connection between the kettle body 1 and the top cover 2 to increase the sealing performance. The excess water flow in the first sealing groove 13 will enter the embedded groove 18 along the drainage groove 14, and finally enter the recovery bottle 16 installed in the embedded groove 18 to be collected.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
