Description

Technical Field

[0001] This utility model relates to the technical field of organic compound production equipment, specifically to a multi-stage condensation and recovery device for efficient coffee aroma extraction. Background Technology

[0002] Coffee aroma is formed by the volatilization of various organic compounds in coffee raw materials, involving a combination of dozens or even hundreds of organic compounds. Considering cost and aroma reproduction, coffee aroma compounds are usually extracted from natural coffee raw materials through methods such as distillation. The extraction process involves different extraction environments for different types of compounds, so multiple sets of distillation extraction equipment are connected in series to extract various volatiles. This requires large-scale industrial equipment to provide technical support. However, in the experimental or technical verification stage, due to the small production volume, it is obviously not suitable to use industrial-grade equipment for production. Therefore, a miniaturized set of equipment that can reproduce the industrial production process is needed for coffee aroma extraction in the experimental and technical verification process.

Detailed Implementation

[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 condenser tube 1, an inlet pipe 2, and an outlet pipe 3. The inlet pipe 2 is connected in series at the left end of the condenser tube 1, and the outlet pipe 3 is connected in series at the right end of the condenser tube 1. The condenser tube 1 is spirally wound in several turns. A connecting pipe 5 is connected in series at the lower part of each turn of the condenser tube 1. A collecting cylinder 4 is located below the condenser tube 1. The connecting pipes 5 are connected in parallel on the upper side wall of the collecting cylinder 4. A crankshaft 14 is spun onto the collecting cylinder 4 via bearings, and the handle end of the crankshaft 14 is located on the left side of the collecting cylinder 4. A sealing plate 15 is fixedly installed on the end of the crankshaft 14, and the sealing plate 15 is movably abutted against the inner wall of the collecting cylinder 4. A storage tank 6 is installed on the side of the collecting cylinder 4, and a guide pipe 7 is connected in series on the collecting cylinder 4. The other end of the guide pipe 7 is fixed to the lower part of the side wall of the storage tank 6. The collecting cylinder 4 and the storage tank 6 are connected through the guide pipe 7. An air pump 8 is fixedly installed on the upper side wall of the storage tank 6. The inlet end of the air pump 8 is inserted through a pipe into the upper part of the side plate of the storage tank 6, and thus the inlet end of the air pump 8 is connected to the storage tank 6. The upper part of the inner cavity of tank 6 is open-ended. An exhaust pipe 9 is installed above the condenser pipe 1. The right end of the exhaust pipe 9 is connected to the outlet pipe 3. An exhaust sleeve 10 is fixedly fitted onto the left end of the exhaust pipe 9. An extension pipe 11 is connected in series to the outlet end of the air pump 8. The upper end of the extension pipe 11 is inserted and fixed into the side wall of the exhaust sleeve 10. An adjusting piston 12 is installed inside the exhaust sleeve 10, and the upper end of the adjusting piston 12 is clamped between the end of the exhaust pipe 9 and the end of the extension pipe 11. An air inlet is fixedly fitted onto the inlet pipe 2. The intake sleeve 13 has an opening on its side wall that is flush with the port of the intake pipe 2. The lower end of the adjusting piston 12 extends out of the exhaust sleeve 10 and is inserted into the intake sleeve 13. The lower end of the adjusting piston 12 is located between the port of the intake pipe 2 and the opening on the intake sleeve 13. A connecting rod 16 is screwed onto the handle of the crankshaft 14 via a rotating shaft. A connecting arm 17 is fixedly installed on the adjusting piston 12 between the exhaust sleeve 10 and the intake sleeve 13. The upper end of the connecting rod 16 is screwed onto the connecting arm 17 via a rotating shaft.

[0018] When using this device, the array of condenser tubes 1 are connected in series. The feed end of the raw material needs to be connected to the port of the air inlet sleeve 13 and the extension tube 11 on the condenser tube 1 through a three-way valve. When the raw material is condensed through the condenser tube 1, the adjusting piston 12 is raised, so that the upper end of the adjusting piston 12 blocks the space between the extension tube 11 and the exhaust pipe 9 inside the exhaust sleeve 10. The lower end of the adjusting piston 12 is moved away, so that the feed end of the raw material is connected to the air inlet pipe 2 through the air inlet sleeve 13. Then the raw material enters the condenser tube 1 through the air inlet pipe 2 for condensation and is discharged as waste gas of this process through the exhaust pipe 3. The condensate accumulates at the bottom of each coil of condenser tube 1. After a certain amount of liquid has accumulated in the condenser tube 1, the adjusting piston 12 is pressed down, so that the adjusting piston 12 blocks the air inlet pipe 2. The extension tube 11 and the exhaust pipe 9 are connected through the exhaust sleeve 10. At this time, the raw material passes through the extension tube 11 and the exhaust pipe 9. The gas pipe 9 is sent to the outlet pipe 3 of this section and enters the condenser pipe 1 of the next process section. The adjusting piston 12 moves downward and presses down the crankshaft 14 through the connecting rod 16. As a result, the crankshaft 14 rotates and drives the sealing plate 15 to rotate and move away from the port of the connecting pipe 5. This allows the collecting cylinder 4 to be connected to each turn of the condenser pipe 1 through the connecting pipe 5. The gas is drawn by the air pump 8. The air pump 8 draws the gas in the storage tank 6 and sends it to the exhaust pipe 9 through the extension pipe 11. The storage tank 6 draws the liquid in the collecting cylinder 4 through the guide pipe 7. At the same time, the gas at one end of the outlet pipe 3 on the condenser pipe 1 of this section flows back into the condenser pipe 1 to push the liquid in the condenser pipe 1, connecting pipe 5, and collecting cylinder 4 into the storage tank 6. The excess waste gas is returned to the outlet pipe 3 by the air pump 8. After the collected liquid is processed, the adjusting piston 12 is reset, so that the device returns to the working state of the inlet pipe 2, condenser pipe 1, and outlet pipe 3 connected in series.

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. This device collects gaseous extracts by condensing them through a spirally arranged condenser tube 1. A collection cylinder 4 is set below the condenser tube 1, and each turn of the condenser tube 1 is connected to the collection cylinder 4 through a connecting pipe 5. An openable and closable sealing plate 15 is set to seal the connecting pipe 5, thereby enabling the periodic collection of liquid in the condenser tube 1. 2. This device has a return exhaust pipe 9 between the collection cylinder 4 and the exhaust pipe 3, and a linkage regulating piston 12 to close the exhaust pipe 9 or the intake pipe 2. This allows the raw material gas to be guided to the next process stage for processing when collecting liquid, and the liquid accumulated in the condenser 1 can be emptied through partial gas return.

[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.
