[0002] Spices, also known as aromatic raw materials, are substances that can be smelled or tasted, and are raw materials for preparing flavors. Natural spices include animal and plant natural spices, which represent the aroma of the animal or plant and can be directly used in flavoring products. At present, steam distillation is commonly used to extract the flavors from the raw materials. The raw materials are usually poured into a distillation cylinder, which is then placed in a distillation kettle chamber. Steam is then introduced from the bottom of the distillation cylinder to evaporate the flavors in the raw materials and form a mixed steam with the water vapor. The mixed steam is condensed through a condenser to obtain a liquid mixture of water and flavors, which is then separated into essential oil products.

[0003] However, in the prior art, when the raw materials are concentrated in the distillation cylinder, the raw materials are too dense, and it is difficult for water vapor to enter the accumulated raw materials to distill the raw materials. The distillation extraction efficiency is low, and part of the steam contacts the inner wall of the guide tube when entering the guide tube and is directly liquefied, which will cause part of the liquid inside the guide tube to flow back into the distillation kettle for repeated distillation, thereby reducing the distillation efficiency of the flavor raw materials. Utility Model Content

[0004] The utility model aims to solve the problem that when the above raw materials are concentrated in the distillation cylinder, the raw materials are too dense, the distillation extraction efficiency is low, and part of the steam flows back into the distillation kettle when entering the guide tube, and part of the liquid flows back into the distillation kettle for repeated distillation, which reduces the distillation efficiency of the essence raw materials.

[0006] Preferably, a positioning frame is fixedly connected to the bottom end of the inner wall of the kettle body, and a limiting groove is provided on the top of the positioning frame, and the diameter length of the limiting groove is smaller than the diameter length of the carrier plate.

[0007] Preferably, a groove is provided at the bottom of the carrier plate, a vent hole is provided at the bottom of the groove, and the surface of the mounting rod passes through the interior of the carrier plate.

[0008] Preferably, a through hole is opened on the surface of the hollow cylinder, the bottom of the hollow cylinder is a hollow structure, the through hole is connected with the hollow end of the hollow cylinder, and the surface of the hollow cylinder passes through the interior of the carrier plate.

[0009] Preferably, the interior of the insulation shell is a hollow structure, and the surface of the insulation shell is respectively fixedly connected with a delivery pipe and a return pipe.

[0010] Preferably, the top ends of the delivery pipe and the return pipe are both connected to the interior of the heat-insulating shell, and the bottom of the delivery pipe is movably connected to the top of the hollow cylinder.

[0011] Preferably, a sealing ring is provided on the inner wall of the heat-insulating shell, and the inner end of the sealing ring is tightly fitted with the outer wall of the guide tube.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the flavor raw materials are laid on the top of multiple carrier plates, and the air holes at the bottom of the carrier plates can circulate steam to heat the flavor raw materials. At the same time, part of the steam enters the hollow tube and flows out from the through hole, which can not only increase the heating area of ​​the flavor raw materials, but also the inside of the hollow tube is in a circulation state, which can prevent the accumulation of flavor raw materials at the bottom from affecting the upward circulation effect of steam.

[0014] 2. In the utility model, the upper and lower ends of the delivery pipe are connected with the insulation shell and the hollow cylinder respectively. Part of the steam entering the hollow cylinder will enter the insulation shell through the delivery pipe, so that the interior of the insulation shell is in a high temperature state. At the same time, the guide pipe is heated. Since the steam needs to be cooled to be liquefied, it can prevent the steam from liquefying at the bend and flowing back into the kettle body.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Example 1

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a distillation kettle for extracting essence, comprising a kettle body 1, an air inlet pipe 11 is fixedly connected to the bottom of the kettle body 1, a top cover 2 is fixedly installed on the top of the kettle body 1, a guide pipe 21 is fixedly connected to the top of the top cover 2, a heat preservation shell 3 is fixedly installed on the top of the top cover 2, one end of the surface of the top cover 2 passes through the interior of the heat preservation shell 3, a mounting rod 4 is arranged inside the kettle body 1, a fixing block 41 is fixedly connected to the top of the mounting rod 4, four carrier plates 5 are fixedly connected to the surface of the mounting rod 4, and the interior of the carrier plate 5 is fixed A hollow cylinder 6 is installed, and a positioning frame 12 is fixedly connected to the bottom end of the inner wall of the kettle body 1. A limiting groove 121 is provided on the top of the positioning frame 12. The diameter length of the limiting groove 121 is smaller than the diameter length of the carrier plate 5. A groove 501 is provided at the bottom of the carrier plate 5. An air vent 502 is provided at the bottom of the groove 501. The surface of the mounting rod 4 passes through the interior of the carrier plate 5. A through hole 601 is provided on the surface of the hollow cylinder 6. The bottom of the hollow cylinder 6 is a hollow structure. The through hole 601 is connected to the hollow end of the hollow cylinder 6. The surface of the hollow cylinder 6 passes through the interior of the carrier plate 5.

[0024] In this embodiment, the flavor raw material is laid on the top of the carrier plate 5, and there is a certain distance between each carrier plate 5. The carrier plate 5 is placed inside the kettle body 1, and the positioning frame 12 supports the carrier plate 5 at the bottom, and the top cover 2 is tightly closed. High-temperature steam is added to the air inlet pipe 11 to heat and distill the flavor raw material. The steam rises and passes through the air holes 502 at the bottom of the carrier plate 5 to heat the bottom of the flavor raw material, and evaporates the volatile flavor in the flavor raw material and mixes with the steam. At the same time, part of the steam enters the hollow cylinder 6 and flows out from the through hole 601. The steam flowing out of the through hole 601 flows evenly to the surface of the raw material, and passes through the air holes 502 together and flows into the guide tube 21, thereby increasing the contact area between the raw material and the steam, thereby increasing the distillation and extraction effect of the raw material.

[0025] Example 2

[0026] like Figure 1-Figure 4 As shown, the interior of the insulation shell 3 is a hollow structure, and the surface of the insulation shell 3 is fixedly connected with a delivery pipe 31 and a return pipe 32, the top ends of the delivery pipe 31 and the return pipe 32 are connected to the interior of the insulation shell 3, the bottom of the delivery pipe 31 is movably connected to the top of the hollow tube 6, and the inner wall of the insulation shell 3 is provided with a sealing ring 33, and the inner end of the sealing ring 33 is tightly fitted with the outer wall of the guide pipe 21.

[0027] In this embodiment, when the steam enters the hollow cylinder 6, due to the upward drift of the steam, part of the steam enters the insulation shell 3 from the delivery pipe 31, and the steam heats the bending part of the guide tube 21, making it in a high temperature state. The steam inside the insulation shell 3 then enters the kettle body 1 again through the reflux pipe 32, and enters the guide tube 21 to be discharged together. When the steam enters the guide tube 21, due to the high temperature at the bending part of the guide tube 21, the steam cannot contact and liquefy with the inner wall of the guide tube 21 at the bending part, thereby preventing the liquid from condensing at the bending part and flowing back into the kettle body 1.

[0028] The working principle of this embodiment is as follows: the flavor raw material is laid on the top of the carrier plate 5, and then the carrier plate 5 is placed inside the kettle body 1, and the top cover 2 is tightly closed, and high-temperature steam is added to the air inlet pipe 11 to heat and distill the flavor raw material. The steam rises through the air vents 502 at the bottom of the carrier plate 5 to heat the bottom of the flavor raw material. At the same time, part of the steam enters the hollow cylinder 6 and flows out from the through hole 601 and flows to the surface of the raw material, thereby increasing the contact area between the raw material and the steam. Part of the steam inside the hollow cylinder 6 enters the insulation shell 3 from the conveying pipe 31, and the steam heats the bending part of the guide tube 21 to keep it in a high temperature state. When the steam enters the guide tube 21, due to the high temperature at the bending part of the guide tube 21, the steam cannot contact and liquefy with the inner wall of the guide tube 21 at the bending part, thereby preventing the liquid from condensing at the bending part and flowing back into the kettle body 1.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
