Abstract
Description
Technical Field
[0001] This utility model relates to the field of coffee technology, specifically to a multi-stage distillation coffee aroma gradient collection device. Background Technology
[0002] Coffee is a special beverage that is warmly welcomed all over the world. Its unique aroma is composed of hundreds of volatile organic compounds. In production and research, it is necessary to purify and analyze the composition of these compounds at different temperatures. Steam distillation is a commonly used extraction method, which has a high recovery rate and good aroma retention.
[0003] However, traditional steam distillation equipment is mostly single-stage, which cannot separate aromas at different temperatures. The purified aroma substances are often highly mixed, and substances with different boiling points and saturated vapor pressures cannot be enriched, which easily leads to a masking effect. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a rationally designed multi-stage distillation coffee aroma gradient collection device, which can solve the aforementioned defects.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a distillation tank, a gas pipe connected to the distillation tank for discharging gas, a collector connected to the gas pipe, a plurality of heat-conducting blocks inside the collector, a curved temperature control pipe in each heat-conducting block, the gas pipe being connected to the temperature control pipe at its end, the plurality of temperature control pipes being connected in sequence, a collection pipe being connected to each temperature control pipe, the collection pipe being connected to the tail end of the temperature control pipe, a flow valve being provided on the collection pipe, and a condenser being connected to the collection pipe.
[0006] Preferably, the heat-conducting block is provided with a spiral tube, which is located outside the temperature control tube, and both ends of the spiral tube are connected to external cooling equipment through cooling pipes.
[0007] Preferably, the heat-conducting block is provided with multiple heating tubes.
[0008] Preferably, a temperature measuring head is provided inside the heat-conducting block.
[0009] Preferably, the temperature control tube is provided with multiple water hoppers at the bottom, and a drain pipe is connected below the water hoppers. The water hoppers are all located in front of the connection between the temperature control tube and the collection pipe.
[0010] Preferably, the collector is provided with a heat insulation layer on the outside of the heat-conducting block.
[0011] The beneficial effects of this utility model after adopting the above structure are:
[0012] This invention features multiple heat-conducting blocks for precise temperature control, ensuring the airflow temperature stabilizes at that temperature before aroma collection. This gradient collection of aromas reduces masking effects, allowing for graded enrichment of different compounds. The design is simple, efficient, and highly stable, facilitating the separation, preservation, or re-blending of different aroma segments to develop coffee products with specific flavors.
[0013] This invention features a water hopper that discharges the condensate generated during the cooling process inside the temperature control tube, preventing the aromas at different temperatures from mixing with the aromas to be collected. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] See Figures 1-4 As shown, it includes a distillation tank 1, with a gas pipe 2 connected to the top of the distillation tank 1 for venting gas. The gas pipe 2 is connected to a collector 3, and the collector 3 has multiple heat-conducting blocks 4 inside to assist in temperature control. Each heat-conducting block 4 has a temperature control pipe 5 arranged in an arc-shaped structure. The gas pipe 2 is connected to the temperature control pipe 5 at the end, and the multiple temperature control pipes 5 are connected in sequence to form a gas path.
[0022] Each temperature control tube 5 is connected to a collection tube 10, which is located at the tail end of the temperature control tube 5 and is used to collect gas. The collection tube 10 is equipped with a flow valve 12 for adjusting the flow rate. The collection tube 10 is also connected to a condenser 11 for condensing the aromatic gas.
[0023] Inside the heat-conducting block 4, there is a spiral tube 6, which surrounds the outside of the temperature control tube 5 and is connected to an external cooling device through a cooling tube 9 to form a cooling circulation system. At the same time, the heat-conducting block 4 also has multiple heating tubes 13 to meet the temperature control requirements and finely adjust the temperature so that the temperature of the heat-conducting block 4 can be stabilized within a specified range. From one end of the gas pipe 2 to the other end, the temperature of the heat-conducting block 4 and the temperature control tube 5 decreases sequentially. In addition, the heat-conducting block 4 is also equipped with a temperature measuring head 14 to monitor the temperature changes inside the system in real time and ensure the stable operation of the system.
[0024] The bottom of the temperature control tube 5 is provided with multiple water hoppers 7, and each water hopper 7 is connected to a drain pipe 8. These water hoppers 7 are all located in front of the connection between the temperature control tube 5 and the collection pipe 10, and are used to discharge the liquid generated by condensation during the temperature drop after entering the temperature control tube 5.
[0025] In addition, an insulation layer is provided on the outside of the collector 3 and the part corresponding to the heat conduction block 4 to reduce heat loss, improve the overall thermal efficiency of the system, and also help maintain the temperature stability of the system.
[0026] The usage process of this utility model:
[0027] After the device is installed, coffee raw materials are extracted, and the distilled aromatic gas is discharged from the gas pipe 2 and then enters the heat-conducting block 4. Cooling liquid is introduced into the cooling pipe 9, which causes the temperature of the heat-conducting block 4 to drop to a specified value. Since the spiral tube 6 is wrapped around the outside of the temperature control tube 5, the temperature at the temperature control tube 5 can drop quickly to a specified range. When the temperature is too low, the heating tube 13 will supplement the heat. After the gas enters the temperature control tube 5, it will be cooled until it reaches the temperature near the temperature of the temperature control tube 5. The condensate generated in this process is discharged from the water tank 7 through the drain pipe 8. Therefore, when the gas reaches the outlet end of the temperature control tube 5, the temperature has tended to be stable. At this time, the flow valve 12 is opened to release a certain amount of gas at this temperature, which enters the condenser 11 for condensation and collection. The remaining gas will continue to flow backward to the temperature control tube 5 at the next temperature point. Thus, the device can collect coffee aroma at different temperature values.
[0028] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
