TECHNICAL FIELD

[0001] The application relates to the technical field of reaction kettle equipment, and particularly relates to a cyclization reaction kettle for furanone synthesis and a processing method thereof. BACKGROUND

[0002] Furanone is a flavor enhancer, which has strong caramel aroma, rich fruit aroma and jam flavor, and raspberry flavor after dilution.

[0003] At present, the synthesis reaction of furanone mainly depends on a reaction kettle. During the synthesis of furanone, external heating is needed to maintain the cyclization reaction of furanone at a proper temperature. For the heating method of the current reaction kettle, the outer wall of the reaction kettle is mainly heated by a heating wire, so that only the outer side of the material in the reaction kettle is heated during the mixing process, the whole material cannot be heated, and the local continuous heating phenomenon exists.

[0004] Meanwhile, after large-particle materials are stirred in the reaction kettle, the particles are deposited due to poor stirring effect, which is not conducive to the fusion of the materials, and the deposited materials may be agglomerated, so that the materials are unevenly distributed, and the quality of the output product is reduced.

[0046] As a second embodiment of the present application, refer to the accompanying Figures 5-8 The expansion pipe mechanism is movably sleeved with the temperature increasing push rod 13 through the side wall of the filter cartridge 12, one end of the temperature increasing push rod 13 is located in the reaction cavity 100, the other end of the temperature increasing push rod 13 is fixedly connected with the blocking rubber pipe 18, the other end of the temperature increasing push rod 13 is fixedly connected with the claw 131 located outside the blocking rubber pipe 18, the adjusting rod 14 located outside the claw 131 is arranged in the heating cavity 101, the adjusting rod 14 is clamped with the claw 131, and the two ends of the adjusting rod 14 are slidably connected with the inside of the kettle shell 1. The sliding connection is based on the rectangular plate movably arranged in the inside of the kettle shell 1, the adjusting rod 14 is fixedly installed with the rectangular plate, and the movement direction of the adjusting rod 14 is limited by the movement of the rectangular plate. At the same time, the rectangular plate also prevents the medium in the heating cavity 101 from leaking. The reset push block 15 is movably installed in the inside of the top end of the kettle shell 1, the top end of the reset push block 15 is located in the reaction cavity 100, the reset push block 15 is fixedly connected with the top end of the adjusting rod 14, and the tail end of the reset push block 15 is movably installed with the reset push spring 150 located in the inside of the kettle cover 2.

The rotation stopping spring rod 5 is composed of two movable guide rods, and the two movable guide rods are away from each other through the elastic element.

[0047] In this embodiment, the temperature increasing push rod 13 is divided into at least six groups, and the multiple groups of temperature increasing push rods 13 are distributed at equal angles on the side wall of the filter cartridge 12. There are eight temperature increasing push rods 13 in one group, and the eight temperature increasing push rods 13 are distributed at equal distances in the axial direction of the filter cartridge 12. The temperature increasing push rod 13 closest to the bottom of the kettle shell 1 is fixedly installed with the adjusting rod 14, and the temperature increasing push rod 13 closest to the bottom of the kettle shell 1 is provided with a ring groove on the outer side. The inside of the filter cartridge 12 movably installs a pressure limiting ball 130 for clamping in the ring groove. Since the temperature increasing push rod 13 is provided with multiple groups, the outer side of each group of temperature increasing push rods 13 is also provided with an adjusting rod 14, thereby ensuring that the whole can stably operate.

[0048] Reference Figure 9 The adjusting rod 14 is a cylindrical rod, and the outer side of the adjusting rod 14 is provided with a triangular clamping groove. The cross-sectional shape of the clamping jaw 131 is C-shaped, and the top of the clamping jaw 131 is provided with clamping teeth matched with the clamping groove. When the clamping jaw 131 is separated from the adjusting rod 14, it has a certain separation strength. The clamping jaw 131 determines the separation strength between the adjusting rod 14 and the clamping jaw 131. Therefore, the clamping tooth width on the clamping jaw 131 increases in sequence from the top end to the low end of the kettle shell 1 in one group of adjusting rods 14, so that when the pressure in the heating cavity 101 gradually increases, the separation sequence of the temperature increasing push rod 13 is to separate from the bottom of the kettle shell 1 first.

[0049] When the embodiment works:

[0050] The raw material is placed in the reaction cavity 100, and the heating medium is introduced into the liquid inlet channel 6 and delivered to the top of the heating cavity 101 through the filter cartridge 12. As the medium in the liquid inlet channel 6 is continuously input, the heating cavity 101 is filled with the medium. At the same time, the injection of the liquid inlet channel 6 will make the driving gear 22 drive the liquid control turntable 4 to rotate synchronously, so that the liquid control hole 400 blocks the liquid discharge channel 104. The surface of the liquid control turntable 4 blocks the liquid discharge channel 104. In the early stage of liquid injection in the heating cavity 101, the low-pressure medium flows from the driving flow channel 103, which is insufficient to drive the power fan 19 to rotate. The power fan 19 stops rotating, which will not rotate the grinding head 3. The movable magnetic block 10 and the fixed magnetic block 9 are relatively moved under the elastic force of the return top spring 11. At this time, the surface of the grinding head 3 is tightly attached to the bottom of the kettle cover 2 due to the magnetic repulsion between the two. The outside of the grinding head 3 drives the reset push block 15, which will compress the reset push spring 150, so that the reset push block 15 drives the adjusting rod 14 to move outward from the heating cavity 101 until the bottom pressure limiting ball 130 is clamped in the ring groove.

[0051] With the heating cavity 101 in the injection of too much medium, the pressure in the drive flow channel 103 is increasing, forcing the power fan 19 to rotate, the rotating power fan 19 will make the movable magnetic block 10 compression reset to the spring 11, the fixed magnetic block 9 and the movable magnetic block 10 are not opposite, the grinding head 3 under its own gravity moves down to the reaction cavity 100, and the particles are ground and crushed through the gap between the grinding head 3 and the filter cartridge 12.

[0052] Due to the increasing pressure of the medium in the heating cavity 101, when the pressure can make the power fan 19 rotate, the further increased medium pressure will push the blocking rubber tube 18 to stick to the outside of the filter cartridge 12. At this time, the claw 131 at the top of the kettle shell 1 will first be separated from the adjusting rod 14. Since the claw 131 and the adjusting rod 14 are separated with a certain resistance, when the pressure in the heating cavity 101 is greater than the resistance, the resistance will disappear instantly, so that the pressure in the heating cavity 101 will shoot the heating raw materials between the filter cartridge 12 and the blocking rubber tube 18 to the middle of the reaction cavity 100, accelerating the mixing of the internal raw materials and uniformly heating the internal temperature.

[0053] With the increasing pressure in the heating cavity 101, the heating push rod 13 at the top of the kettle shell 1 will gradually separate from the adjusting rod 14, and the heating push rod 13 extending into the reaction cavity 100 will be on the top inclined angle of the grinding head 3. Therefore, when the grinding head 3 is insufficiently pressed due to its own gravity, the grinding intensity is further enhanced by the advancement of the heating push rod 13. The height of the inclined surface at the top of the grinding head 3 is sufficient to cross two heating push rods 13, so that the adjacent two heating push rods 13 in the vertical direction will not be stuck by the grinding head 3 due to simultaneous ejection.

[0054] With the continuous downward movement of the grinding head 3, until the grinding head 3 is pressed at the bottom of the reaction cavity 100, when the pressure in the heating cavity 101 increases to a certain extent, the rotation speed of the power fan 19 also increases, increasing the stirring speed. When the pressure in the heating cavity 101 makes the heating push rod 13 separate from the pressure limiting ball 130, the grinding head 3 has already fallen to the bottom of the kettle shell 1 at this time. The medium pressure in the heating cavity 101 and the elastic force of the reset push spring 150 make the claw 131 move towards the blocking rubber tube 18, combined with the decompression ring 8, at this time, the adjusting rod 14 moving to the right side will reduce the strength of pressing the decompression ring 8, and the decompression ring 8 will be lifted under the elastic force of the decompression spring 7. The lifted decompression ring 8 will drive the stop spring rod 5 to move up and separate from the liquid control hole 400. Figure 6

[0055] ​For the rotation of the liquid control disc 4, the rotation of the liquid control disc 4 is prevented by the rotation of the liquid control disc 4, and only after the above-mentioned action is realized, the liquid control hole 400 is separated from the liquid inlet channel 6, and the liquid control hole 400 is connected to the liquid outlet channel 104.

[0056] With the rotation of the liquid control disc 4, the medium in the heating cavity 101 is discharged from the liquid outlet channel 104, causing the medium in the driving flow channel 103 to decrease, and the driving fan 19 does not rotate. The rotating grinding head 3 is again moved upward under the magnetic repulsion of the movable magnetic block 10 and the fixed magnetic block 9. During the upward movement of the grinding head 3, the pressure limiting ball 130 cannot be clamped in the annular groove due to the upward movement of the temperature increasing push rod 13, so that the grinding head 3 cannot push the lowest temperature increasing push rod 13 back. Under the elastic force of the reset push spring 150, the adjusting rod 14 is still close to the blocking rubber tube 18. After the grinding head 3 moves upward and drives the temperature increasing push rod 13 above, the clamping jaw 131 is clamped on the adjusting rod 14 again, until the grinding head 3 moves to the top, forcing the reset push block 15 to drive the adjusting rod 14 away from the blocking rubber tube 18, until the pressure limiting ball 130 is clamped in the annular groove.

[0057] Finally, with the rotation of the liquid control disc 4, the liquid outlet channel 104 is again blocked, the medium in the driving flow channel 103 is increased, and the driving fan 19 is rotated again. According to the above-mentioned cycle, after the processing is completed, the raw material can be discharged through the discharge channel 102.

[0058] In summary, the processing method of the cyclization reaction kettle for furanone synthesis is as follows:

[0059] S1, open the kettle cover 2, add raw materials to the reaction cavity 100, and close the kettle cover 2 tightly;

[0060] S2, the heating medium is introduced into the heating cavity 101 through the liquid inlet channel 6, the pressure in the heating cavity 101 is increased, the stirring and grinding mechanism is forced to stir the raw materials in the reaction cavity 100, the pressure medium in the heating cavity 101 is pressed into the reaction cavity 100 through the expansion tube mechanism between the filter cartridge 12 and the blocking rubber tube 18, and the raw materials are mixed and the temperature is uniformly increased;

[0061] S3, the grinding head 3 moves downward to the bottom, and the liquid control hole 400 is connected to the liquid outlet channel 104, and the grinding mechanism is moved upward again by magnetic repulsion, realizing the next grinding;

[0062] S4, the above-mentioned cycle, the grinding head 3 is stirred by constantly moving up and down, while the filter cartridge 12 and the rubber tube 18 between the barrier will be constantly local heating of the raw materials into the reaction chamber 100, to accelerate the uniformity of the heating;

[0063] S5, finally, the finished raw materials from the discharge way 102 output.
