Description

Technical Field

[0001] This utility model relates to the technical field of organic compound production and processing equipment, specifically to a continuous circulating distillation device for extracting coffee aroma. Background Technology

[0002] Coffee aroma is produced by the volatilization of organic matter from fermented coffee products. It is the result of the combined action of dozens or even hundreds of different types of organic matter. Therefore, in the production of coffee aroma substances, the production process to ensure the purity of coffee aroma substances is to extract aromatic substances from the organic matter in natural coffee products. This requires soaking the raw materials and extraction distillation during the processing. In actual production, existing distillation equipment only uses the extract obtained from the previous process for distillation, or some equipment distills the solid material remaining after soaking at the same time. This results in low distillation efficiency, which may prevent the extraction of some small amounts of substances. As a result, the obtained coffee aroma product is not pure and well-reproduced. Therefore, it is necessary to improve and develop distillation equipment. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a continuous circulating distillation device for extracting coffee aroma. This device achieves solid-liquid separation of the material by adding a filtration pretreatment device at the front end of the distillation process, and fully extracts the effective components of the material through secondary washing, ensuring the integrity of the aromatic substances in the distillate. As a result, a better and more authentic coffee aroma substance can be obtained after distillation.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1-4 As shown, the specific implementation adopts the following technical solution: This specific embodiment includes a housing 1, a feeding hopper 2, a screen chain plate 3, and a primary dewatering unit 7. The housing 1 has an opening at the top. The feeding hopper 2 is fixedly mounted on the upper left side plate of the housing 1 and is internally connected to the housing 1. Two sets of drive roller units 4 are installed inside the housing 1. One set of drive roller units 4 has a screen chain plate 3 wound in a closed loop around it. The screen chain plate 3 is horizontally positioned, with its left end extending below the lower end of the feeding hopper 2. Guide ramps 9 are symmetrically fixed on the front and rear inner walls of the housing 1. The lower side is movably abutted against the upper side wall of the screen chain plate 3. Another set of drive roller units 4 is equipped with a feeding chain plate 8 in a closed loop, and the feeding chain plate 8 is inclined with the right end facing upward. The left end of the feeding chain plate 8 extends below the right end of the screen chain plate 3. A collection hopper 6 is fixedly installed on the right side plate of the box body 1, and the right end of the feeding chain plate 8 extends into the collection hopper 6. A liquid collection tank 5 is integrally formed at the bottom of the box body 1, and the screen chain plate 3 is mounted above the liquid collection tank 5. A primary dewatering unit 7 is installed on the side of the box body 1, and the inlet end of the primary dewatering unit 7 is connected to the outlet end of the collection hopper 6. A through-connection is provided. A collection box 10 is provided on the side of the primary dewatering unit 7, and the upper part of the collection box 10 is open. The solid material outlet of the primary dewatering unit 7 is connected to the upper port of the collection box 10 through a pipe. A dispersing roller unit 12 is provided inside the upper port of the collection box 10. A spiral feeding roller unit 13 is provided inside the collection box 10 below the dispersing roller unit 12. A secondary dewatering unit 11 is provided on the side of the collection box 10. The outlet of the collection box 10 is connected to the inlet of the secondary dewatering unit 11. A fixed liquid collection box 5 is provided. There is a guide pipe 14, and the outlet end of the guide pipe 14 extends into the upper port of the collection box 10. A drain pipe 15 is connected in series on the liquid outlet end of the primary dewatering unit 7. The liquid outlet end of the secondary dewatering unit 11 is connected to the drain pipe 15 through a pipe. In this device, the drive roller unit 4, the dispersing roller unit 12, and the spiral feeding roller unit 13 are all driven by external motors. The primary dewatering unit 7 and the secondary dewatering unit 11 are roller extrusion dewatering structures, and are equipped with solid-liquid separation kits and electric drive kits. An electromagnetic throttle valve is installed on the guide pipe 14.

[0018] When using this device, the soaked material is poured into the equipment through the feeding hopper 2. The material falls onto the screen chain plate 3 through the feeding hopper 2, so that the liquid in the material falls into the collection tank 5, while the solid material remains on the screen chain plate 3. The solid material is guided by the guide slope plate 9 and accumulates in the middle area of ​​the screen chain plate 3. The drive roller unit 4 drives the screen chain plate 3 to move forward, thereby feeding the material onto the feeding chain plate 8. The drive roller unit 4 drives the feeding chain plate 8 to move forward, thereby feeding the solid material into the collection hopper 6. The solid material enters the primary dewatering unit 7 through the collection hopper 6 for dewatering and compression. The dense solid material produced by dewatering is discharged through the solid material outlet end of the primary dewatering unit 7 and falls into the collection tank 10. The liquid material produced by dewatering enters the drain pipe through the liquid material outlet end of the primary dewatering unit 7. Within 15, dense solid material falls into the collection box 10. The dispersing roller unit 12 rotates to disperse the solid material into loose solid material. A portion of the liquid in the liquid collection box 5 is introduced into the collection box 10 through the guide pipe 14, thereby rinsing the dispersed loose solid material. This process dissolves the useful substances in the loose solid material a second time, forming a mixture. The mixture is then fed into the secondary dehydration unit 11 through the screw feed roller unit 13. The mixture is dehydrated in the secondary dehydration unit 11. The solid waste generated during dehydration is discharged from the solid material outlet of the secondary dehydration unit 11, while the liquid material generated during dehydration enters the drain pipe 15 from the liquid material outlet of the secondary dehydration unit 11. Finally, the liquid material in the collection box 5 and the liquid material in the drain pipe 15 are collected and sent for distillation, thus achieving the distillation processing of the material.

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. This device uses a screen chain plate 3 and a primary dewatering unit 7 to dewater the soaked material by screening and filtering, thereby removing most of the liquid from the material. Then, the material is further dewatered by the primary dewatering unit 7, which quickly separates the solution from the material for subsequent distillation. 2. This device is equipped with a two-stage dewatering unit 11, and a collection box 10 with a dispersing roller unit 12 is set between the first-stage dewatering unit 7 and the second-stage dewatering unit 11. A guide pipe 14 is set from the liquid collection box 5 and connected to the collection box 10 to realize the secondary dissolution of the dense solid material after the first dewatering, so as to fully extract and collect the effective components in the solid material.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
