[0001] The invention relates to the technical field of preparation of cooling agents, and in particular to a method for producing cooling agents based on chemical synthesis. Background Art

[0002] Cooling agents are a class of chemical substances that can produce a cooling sensation on the human body or skin. They are commonly used in food, beverages, cosmetics and medicines. These substances activate cold receptors by contacting the human skin surface or receptors, thereby producing a refreshing feeling. The cooling sensation of cooling agents comes from their physical or chemical effects on the skin. Common cooling agents include menthol, peppermint oil, capsaicin, etc.

[0003] In the prior art, a distillation method is usually used to extract peppermint oil from peppermint leaves. Although this method can extract peppermint oil simply and quickly, the following problems still exist: when the distillation method is used to extract peppermint oil, a large amount of peppermint leaves are distilled simultaneously in industrial production. When steam passes through the mint leaves, the mint leaves are piled together, so that the contact between the steam and the mint leaves is insufficient, and the steam can only directly act on the surface layer of the mint leaves. When the steam takes away the peppermint oil inside the mint leaves, part of the mixed steam will adhere to the inner wall of the distillation cylinder and cannot be collected, which affects the production efficiency and quality. Summary of the invention

[0004] In view of the problems in the prior art that the accumulation of mint leaves results in the inability of steam to fully contact the internal mint leaves, and a large amount of raw material mixture adheres to the inner wall of the distillation cylinder and cannot be collected, a method for producing a cooling agent based on chemical synthesis is proposed.

[0005] The present application provides a method for producing a cooling agent based on chemical synthesis, the purpose of which is: by setting a one-way bearing, when the servo motor rotates forward, the mint leaves can be continuously flipped through the flipping component, so that the steam below can contact more mint leaves, effectively improving the distillation efficiency and quality; when the servo motor reverses, the upward moving liquid collecting ring can collect the raw material mixture attached to the inner wall in the liquid collecting ring through the collecting component, and the collected raw material mixture is drained into the cooling cylinder for collection.

[0006] The technical solution of the present invention is: a method for producing a cooling agent based on chemical synthesis, comprising the following steps:

[0008] S2, raw material processing: chopping the dried mint leaves and placing them in a distillation unit;

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] Example 1, reference Figure 1 - Figure 5 , which is the first embodiment of the present invention, provides a method for producing a cooling agent based on chemical synthesis,

[0040] The following steps are involved:

[0041] S1. Raw material preparation: collect fresh mint leaves, clean and dry them;

[0042] S2, raw material processing: chopping the dried mint leaves and placing them into the distillation unit;

[0043] S3, distillation occurs: the water at the bottom of the distillation unit is heated to boiling, and the water vapor produced passes through the mint leaves above;

[0044] S4, treating the inner wall of the cylinder: draining the product mixture attached to the inner wall through the distillation unit;

[0045] S5, condensation: condensing the steam of the mint leaves and the volatile mint oil mixture into a liquid and collecting it;

[0046] S6, separation: after condensation, the mixed liquid flows into a separator to separate the peppermint oil and water, and collect the peppermint oil;

[0047] S7. Collection and storage: Collect the separated peppermint oil and store it in a light-proof, airtight container.

[0048] The distillation unit includes a distillation cylinder 2, and also includes a collecting component and a flip component arranged in the distillation cylinder; the collecting component includes a mounting plate 1, a distillation cylinder 2 fixedly mounted on the mounting plate 1, a water inlet 3 provided on the bottom side wall of the distillation cylinder 2, a steam outlet 4 provided above the side wall of the distillation cylinder 2, a heating tube 5 fixedly mounted on the bottom end of the inside of the distillation cylinder 2, a partition plate 6 fixedly mounted on the bottom of the inner wall of the distillation cylinder 2, a liquid dispersion plate 7 fixedly mounted on the upper end of the distillation cylinder 2, a water guide ring 8 fixedly mounted on the bottom end of the liquid dispersion plate 7, a servo motor 9 fixedly mounted on the upper end of the liquid dispersion plate 7, a reciprocating screw 10 rotatably mounted on the liquid dispersion plate 7, a ball nut 11 threadedly mounted on the reciprocating screw 10, a plurality of connecting rods 12 fixedly mounted on the ball nut 11, a transmission ring 13 fixedly mounted between the plurality of connecting rods 12, a one-way bearing 14 fixedly mounted on the outer ring of the transmission ring 13, a liquid collecting ring 15 fixedly mounted on the outer ring of the one-way bearing 14, and a flow component is arranged on the liquid collecting ring 15;

[0049] The driving end of the servo motor 9 is fixedly connected to the upper end of the reciprocating screw 10, a plurality of circular holes for the flow of water vapor are provided on the partition plate 6, the bottom end surface of the liquid dispersion plate 7 is a cone, the lower end of the water guide ring 8 is chamfered, a feed port 16 is provided on the liquid dispersion plate 7, and the water guide ring 8 is located directly above the liquid collecting ring 15.

[0050] Reference Figure 3 - Figure 4 and Fig. 9 The flow component includes an inclined ring 17 fixedly installed inside the liquid collecting ring 15, a through groove 18 opened on the liquid collecting ring 15, and a limiting rod 19 fixedly installed on the inner wall of the distillation cylinder 2. The limiting rod 19 has the same end face shape as the through groove 18, and the limiting rod 19 is located in the through groove 18. The lowest point of the inclined ring 17 is located at the through groove 18, and the steam outlet 4 is located directly above the limiting rod 19.

[0051] Specifically, the working principle of the one-way bearing 14 is that when the inner ring of the one-way bearing 14 rotates in the forward direction, the inner ring drives the outer ring to rotate synchronously. When the inner ring of the one-way bearing 14 rotates in the reverse direction, the inner ring does not drive the outer ring to rotate, and then the inner ring rotates relative to the outer ring. Figure 6 , the one-way bearing 14 is rotated clockwise again for positive rotation, and the one-way bearing 14 is rotated counterclockwise for reverse rotation.

[0052] The collecting component is used to collect a large amount of raw material mixture attached to the inner wall of the distillation cylinder 2 after the distillation is completed, and drain the collected raw material mixture out of the distillation cylinder 2 by drainage, and perform subsequent processing on it. When the one-way bearing 14 rotates forward, its inner ring drives the outer ring, so that when the driving end of the servo motor 9 drives the reciprocating screw 10 to rotate forward, the inner ring of the one-way bearing 14 will drive the outer ring to rotate. Because the limit rod 19 is located in the through groove 18, the limit rod 19 will limit the liquid collecting ring 15, so that when the reciprocating screw 10 rotates, it will drive the collecting ring through the ball nut 11. The liquid ring 15 moves upward along the inner wall of the distillation cylinder 2. During the upward movement of the liquid collecting ring 15, the chamfer on the liquid collecting ring 15 can scrape the raw material mixture attached to the inner wall into the interior of the liquid collecting ring 15 for collection. At the same time, when the liquid collecting ring 15 moves upward to the highest point, the lower end of the through groove 18 of the liquid collecting ring 15 is still located at the uppermost end of the limiting rod 19, and the through groove 18 is connected to the steam outlet 4. At this time, the raw material mixture collected by the liquid collecting ring 15 flows into the through groove 18 under the action of the inclined surface on the inclined ring 17, and flows into the condenser 31 for collection under the action of gravity.

[0053] During use, when distillation is completed, the servo motor 9 is controlled to rotate forward, so that the servo motor 9 drives the transmission ring 13 and the inner ring of the one-way bearing 14 to rotate forward through the reciprocating screw 10, thereby driving the outer ring of the one-way bearing 14 and the liquid collecting ring 15 to rotate. However, since the limit rod 19 is located in the through groove 18, the liquid collecting ring 15, the one-way bearing 14 and the transmission ring 13 cannot rotate normally, and then under the action of the torsional force of the ball nut 11 and the reciprocating screw 10, the ball nut 11 will be driven The dynamic transmission ring 13 and the liquid collecting ring 15 move upward, and the raw material mixture attached to the inner wall of the distillation cylinder 2 is collected in the liquid collecting ring 15 during the upward movement. When the liquid collecting ring 15 rises to the highest point, the lower end of the through groove 18 is just located at the uppermost end of the limiting rod 19. At this time, the through groove 18 is connected with the steam outlet 4, and the raw material mixture in the liquid collecting ring 15 flows into the steam outlet 4 under the action of the inclined ring 17, thereby completing the collection and drainage of the collected raw material mixture.

[0054] Example 2, reference Figure 4-8, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the flip component includes two bearing plates 20 fixedly installed at the lower end of the liquid collecting ring 15, driven gears 21 rotatably installed on the side walls of the two bearing plates 20, respectively, driving gears 22 rotatably installed on the side walls of the two bearing plates 20, respectively, a flip rod 23 fixedly installed between the side walls of the two driven gears 21, and a rotating gear ring 24 fixedly installed at the lower end of the transmission ring 13. The two driven gears 21 are meshed with the corresponding driving gears 22, and the two driving gears 22 are meshed with the rotating gear ring 24.

[0055] Specifically, the flipping component is used to flip the mint leaves inside the distillation cylinder 2 continuously during the distillation process, so that the steam below can better contact the accumulated mint leaves, thereby improving the distillation efficiency. Its working principle is that when the servo motor 9 rotates in the opposite direction, the ball nut 11 drives the transmission ring 13 to rotate in the opposite direction, and because the inner ring of the one-way bearing 14 rotates in the opposite direction, it will not drive the liquid collecting ring 15 to rotate in the opposite direction, and then the transmission ring 13 will rotate with the reverse rotation of the reciprocating screw 10 when it is not limited, and then the liquid collecting ring 15 will not drive the transmission ring 13 to move in the vertical direction, and the transmission ring 13 can only rotate relative to the liquid collecting ring 15. When the transmission ring 13 rotates, the rotating gear ring 24 at its lower end will drive the driving gear 22 to rotate, and then drive the corresponding driven gear 21 to rotate. When the driven gear 21 rotates, it will drive the flipping rod 23 to flip continuously. During the flipping process of the flipping rod 23, the mint leaves are flipped, so that it can be better distilled. Therefore, by setting the one-way bearing 14, different technical effects can be achieved by using different rotation directions of the servo motor 9.

[0056] During use, when the mint leaves are distilled, the servo motor 9 is controlled to rotate in the reverse direction, and then the transmission ring 13 is driven to rotate in the reverse direction through the ball nut 11. At this time, the transmission ring 13 will rotate synchronously with the ball nut 11, and the reverse rotation of the inner ring of the one-way bearing 14 will not drive the outer ring to rotate. Therefore, when the servo motor 9 reverses, it will only drive the transmission ring 13 to rotate synchronously. When the transmission ring 13 drives the rotating gear ring 24 at the lower end to rotate, the rotating gear ring 24 will drive the driving gear 22 at the lower end to rotate, and the rotation of the driving gear 22 will drive the driven gear 21 to rotate. When the two driven gears 21 rotate, the flip rod 23 is driven to rotate, and then the mint leaves are continuously flipped, so that the generated water vapor can better contact the mint leaves.

[0057] The remaining structures are the same as those of Example 1.

[0058] Example 3, reference Figure 1 - Figure 2, which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: a water pump 25 is fixedly mounted on the mounting plate 1, and a water delivery pipe 26 and a water inlet pipe 27 are arranged on the water pump 25, and one end of the water inlet pipe 27 is connected with the water inlet 3. A plurality of support rods 28 are fixedly mounted on the mounting plate 1, and a cooling cylinder 29 is fixedly mounted on the plurality of support rods 28, and the lower ends of the plurality of support rods 28 are all sleeved with rubber sleeves, and a liquid discharge pipe 30 is fixedly connected to the side wall of the cooling cylinder 29. A condenser 31 is fixedly mounted at the steam outlet 4 of the distillation cylinder 2, and a condensation plate 32 is fixedly mounted on the side wall of the condenser 31, and one end of the condenser 31 away from the distillation cylinder 2 is fixedly connected to the upper end of the cooling cylinder 29.

[0059] Specifically, the water pump 25 is used to provide water to the distillation cylinder 2, and a water level detector (not shown in the figure) is arranged inside. The water level detector is electrically connected to the water pump 25. When the water level detector detects that the internal water level is lower than the threshold value, the water level detector controls the water pump 25 so that the water pump 25 provides water to the distillation cylinder 2 so that the water level reaches the threshold value. The condenser 31 is used to condense water vapor and volatile gases so that the two are condensed into liquid after entering the condenser 31 and flow from the condenser 31 into the cooling cylinder 29 under the action of gravity. The cooling cylinder 29 is used to collect the raw material mixture for subsequent processing.

[0060] The remaining structure is the same as that of Example 2.

[0061] Based on Examples 1-3, the distillation method steps are as follows:

[0062] S1. Raw material preparation: The staff collects fresh mint leaves, cleans them and dries them;

[0063] S2, raw material processing: chop the dried mint leaves and place them inside the distillation cylinder 2 and above the partition plate 6;

[0064] S3, distillation occurs: water is provided to the distillation cylinder 2 through the water pump 25, and the heating tube 5 is turned on. The heating tube 5 heats the water at the bottom to boiling, and the generated water vapor passes through the mint leaves above. When the mint leaves are distilled, the servo motor 9 is controlled to rotate in the opposite direction, and then the transmission ring 13 is driven to rotate in the opposite direction through the ball nut 11. At this time, the transmission ring 13 will rotate synchronously with the ball nut 11, and the reverse rotation of the inner ring of the one-way bearing 14 will not drive the outer ring to rotate. Therefore, when the servo motor 9 reverses, it will only drive the transmission ring 13 to rotate synchronously. When the transmission ring 13 drives the rotating gear ring 24 at the lower end to rotate, the rotating gear ring 24 will drive the driving gear 22 at the lower end to rotate, and the rotation of the driving gear 22 will drive the driven gear 21 to rotate. When the two driven gears 21 rotate, they drive the flip rod 23 to rotate, and then the mint leaves are continuously flipped, so that the generated water vapor can better contact the mint leaves;

[0065] S4, treating the inner wall of the cylinder: when the distillation is completed, the servo motor 9 is controlled to rotate forward, so that the servo motor 9 drives the transmission ring 13 and the inner ring of the one-way bearing 14 to rotate forward through the reciprocating screw 10, and then drives the outer ring of the one-way bearing 14 and the liquid collecting ring 15 to rotate. However, because the limit rod 19 is located in the through groove 18, the liquid collecting ring 15, the one-way bearing 14 and the transmission ring 13 cannot rotate normally, and then under the action of the torsional force of the ball nut 11 and the reciprocating screw 10, the ball nut 11 will drive the transmission ring 13 and the liquid collecting ring 15 moves upward, and the liquid collecting ring 15 collects the raw material mixture attached to the inner wall of the distillation cylinder 2 in the liquid collecting ring 15 during the upward movement. When the liquid collecting ring 15 rises to the highest point, the lower end of the through groove 18 is just located at the uppermost end of the limit rod 19. At this time, the through groove 18 is connected with the steam outlet 4, and the raw material mixture in the liquid collecting ring 15 flows into the steam outlet 4 under the action of the inclined ring 17. The collected raw material mixture flows into the condenser 31 through the steam outlet 4, and flows into the cooling cylinder 29 through the condenser 31 for collection;

[0066] S5, condensation: when the steam and volatile peppermint oil mixture enters the condenser tube 31, it condenses into liquid under the condensation of the condenser plate 32, and flows into the cooling cylinder 29 for collection under the action of gravity;

[0067] S6, separation: after condensation, the mixed liquid flows into a separator (extractor). Since the density of peppermint oil is lower than that of water, the peppermint oil and water will be separated by stratification. The peppermint oil and water are separated by this principle, and the peppermint oil is collected;

[0068] S7. Collection and storage: Collect the separated peppermint oil and store it in a light-proof, airtight container.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
