Description

Technical Field

[0001] This utility model belongs to the field of coffee liquid circulation technology, specifically relating to a device for circulating instant coffee liquid. Background Technology

[0002] Coffee concentrate is a complex liquid that exists in various states, including solutions and suspensions. The standard processing flow for coffee concentrate is: green coffee beans—screening—roasting—grinding—extraction—separation—concentration—clarification—sterilization—metal detection—packaging—freezing—finished product. Instant coffee concentrate is a ready-to-drink coffee product made from concentrated coffee extract. It can be directly diluted with water and consumed without brewing or filtering. Waste liquids generated during the industrial production of instant coffee are primarily produced during the coffee extraction, concentration, and drying stages.

[0003] Chinese patent CN217791336U discloses an instant coffee powder granulation device, including a spray gun base. The spray gun base has several vertical high-pressure gun rods arranged along the circumference from top to bottom. The bottom of the spray gun base is connected to a drying tower, which effectively reduces manufacturing costs and ensures that the coffee particles have good water solubility. However, the evaporated water contains caffeine and aromatic compounds. Existing technologies basically discharge wastewater, which is quite wasteful. Utility Model Content

[0011] Preferably, the scraper is inclined and the scraper is in contact with the inner wall of the dust guide pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model utilizes a systematic process of atomizing nozzles, heating and evaporation, and exhaust condensation to efficiently evaporate and re-condense the water in the waste liquid after coffee extraction. The recovered high-purity water can be reused to extract coffee powder. The recovered water can significantly improve the flavor purity and quality of the coffee extracted later, while greatly reducing water consumption and wastewater discharge, making it both environmentally friendly and economical.

[0014] 2. This utility model, through its unique funnel-shaped dust guide pipe design and the matching position of the heating pipe, achieves secondary drying of residual liquid that has not evaporated in time and effective collection and guidance of solid coffee dust, maximizing solid-liquid separation and preventing residual liquid or wet powder from accumulating, hardening or clogging inside the equipment, thus ensuring the stability and continuity of system operation.

[0015] 3. This utility model uses an optimized gear transmission system to drive the scraper, achieving automatic, gentle, and effective cleaning of the inner wall of the dust guide tube. This significantly reduces equipment maintenance needs and extends the life of key components. It effectively removes coffee dust adhering to the inner wall of the dust guide tube, preventing scale buildup from affecting heat conduction and dust fall. At the same time, the gentle scraping greatly reduces friction and wear between the scraper and the inner wall of the dust guide tube, protecting key contact surfaces. This significantly reduces equipment maintenance frequency and component replacement costs, extending the service life of the entire device. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides an instant coffee liquid circulation device, including a drying tank 1 and an atomizing nozzle 3 installed on the top surface of the drying tank 1. A liquid delivery pipe 2 is fixedly connected to the surface of the atomizing nozzle 3, and the end of the liquid delivery pipe 2 away from the atomizing nozzle 3 is connected to an external water pump. A gas-gathering hood 4 is fixedly connected to the top surface of the drying tank 1, and a fan hood 5 is fixedly connected to the end of the gas-gathering hood 4 away from the drying tank 1. A fan is installed inside the fan hood 5, and an air pipe 6 is fixedly connected to the fan hood 5 away from the gas-gathering hood 4. A condenser 7 is installed on one side of the drying tank 1, and the air pipe 6 is fixedly connected to the condenser 7. A heating pipe 9 is installed on the inner wall of the drying tank 1 and is electrically connected to an external power source. When it is necessary to circulate the waste liquid... During recycling, an external water pump draws coffee liquid into the infusion tube 2, and then the atomizing nozzle 3 sprays the coffee liquid into the drying tank 1 in a mist form. At the same time, the heating tube 9 is connected to an external power source, so that the heating tube 9 is energized and heats up, causing the coffee liquid sprayed into the drying tank 1 to evaporate, thus evaporating the moisture inside the coffee liquid. Simultaneously, the fan inside the fan shroud 5 is connected to an external power source and starts. The fan will draw water vapor into the air pipe 6 through the air collection shroud 4, and then discharge it into the condenser 7 through the air pipe 6. The condenser 7 cools the water vapor into liquid, and then the liquid is recycled and used again for the extraction of coffee powder next time, resulting in a better coffee flavor.

[0023] In this embodiment, a dust guide pipe 8 is fixedly connected to the inner wall of the drying tank 1, and a heating pipe 9 is located between the dust guide pipe 8 and the drying tank 1. The dust guide pipe 8 has a funnel-shaped structure, which is wider at the top and narrower at the bottom. Some liquid that fails to separate solid and liquid in time will fall onto the surface of the dust guide pipe 8. Due to the heating of the heating pipe 9, the dust guide pipe 8 will heat the liquid on its surface, causing the moisture on the inner wall to evaporate, leaving only coffee dust. The funnel-shaped dust guide pipe 8 will then let the coffee dust fall downwards.

[0024] In this embodiment, a fixed shell 10 is fixedly connected to the surface of the drying tank 1. A first gear 12 is rotatably connected inside the fixed shell 10 via a shaft. A second gear 13 is disposed inside the fixed shell 10, and the second gear 13 meshes with the first gear 12. A motor 11 is mounted on the top surface of the fixed shell 10. The output shaft of the motor 11 passes through the surface of the fixed shell 10 and is fixedly connected to the second gear 13. Scrapers 14 are uniformly fixedly connected to the inner wall of the first gear 12. The diameter of the first gear 12 is larger than the diameter of the second gear 13, and they cooperate to form a reduction gear structure. 4 is inclined, and the scraper 14 is in contact with the inner wall of the dust guide pipe 8. While drying, the motor 11 is connected to an external power source and started. The motor 11 will drive the first gear 12 to rotate inside the fixed shell 10 through the second gear 13. The rotation of the first gear 12 will drive the scraper 14 to slide on the inner wall of the dust guide pipe 8. The rotation of the scraper 14 will scrape off the dust adhering to the inner wall of the dust guide pipe 8. The second gear 13 has a smaller diameter than the first gear 12 so that the scraper 14 rotates slowly, making the scraping more gentle and reducing the friction between the scraper 14 and the dust guide pipe 8.

[0025] It should be noted that the motor 11, fan, etc. are existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0026] The use of this utility model involves the following steps:

[0027] S1: When it is necessary to recycle the waste liquid, the coffee liquid is pumped into the infusion pipe 2 by an external water pump, and then sprayed into the drying tank 1 in a mist form by the atomizing nozzle 3. At the same time, the heating tube 9 is connected to an external power source, so that the heating tube 9 is energized and heated, so that the coffee liquid sprayed into the drying tank 1 is heated and evaporated, and the water in the coffee liquid is evaporated. At the same time, the fan inside the fan shroud 5 is connected to an external power source and started. The fan will draw water vapor into the air pipe 6 through the air shroud 4, and then discharge it into the condenser 7 through the air pipe 6. The condenser 7 cools the water vapor into liquid, and then the liquid is recycled and used again for the extraction liquid of the next coffee powder, so as to make the coffee flavor better.

[0028] S2: Some liquid that fails to be separated from solid in time will fall onto the surface of the dust guide tube 8. Due to the heating of the heating tube 9, the dust guide tube 8 will heat the liquid on its surface, causing the water on the inner wall to evaporate, leaving only coffee dust. The funnel-shaped dust guide tube 8 will then let the coffee dust fall downwards.

[0029] S3: While drying, connect motor 11 to an external power source and start it. Motor 11 will drive first gear 12 to rotate inside fixed housing 10 through second gear 13. The rotation of first gear 12 will drive scraper 14 to slide on the inner wall of dust guide pipe 8. The rotation of scraper 14 will scrape off the dust adhering to the inner wall of dust guide pipe 8. The diameter of second gear 13 is smaller than that of first gear 12 so that scraper 14 rotates slowly, making scraping gentler and reducing friction between scraper 14 and dust guide pipe 8.
