Technical Field
[0001] This utility model relates to the field of coffee processing technology, specifically to a coffee enzymatic fermentation reactor. Background Technology
[0002] Coffee is one of the world's most popular beverages. Coffee beans are the raw material for making coffee. During the production and processing of coffee, concentration is required. Common modern concentration equipment includes concentration tanks. Coffee is a beverage made from roasted coffee beans and, along with cocoa and tea, is one of the world's most popular drinks. A Chinese patent (authorization announcement number CN209711364U) discloses a coffee active ingredient extraction device, including a reaction vessel body. A feed hopper is inserted into the reaction vessel body, and the lower end of the reaction vessel body is conical. A hollow heating chamber is provided on the outer wall of the lower end of the reaction vessel body. A motor is located above the feed hopper, and a first stirring rod is connected to the lower end of the motor. The end of the first stirring rod away from the motor extends into the reaction vessel body, and a mounting plate is rotatably sleeved at the extended end of the first stirring rod. This coffee active ingredient extraction device features an internal stirring structure that agitates the material, preventing it from settling at the bottom and improving concentration. The rotating stirring structure also drives a scraper to remove material from the inner wall, further enhancing concentration. A crushing plate further breaks down the coffee beans, ensuring complete reaction and increasing efficiency. This patented technology solves the problems of existing technologies where material accumulates at the bottom of the device due to gravity, resulting in poor concentration, material adhering to the inner wall and increasing cleaning difficulty, and poor bean crushing during extraction, leading to incomplete reaction and material waste.
[0003] However, in the existing technology, the reaction vessel after coffee enzymatic fermentation is prone to the growth of fermented bacteria inside after cleaning, which may affect the next coffee enzymatic fermentation process. It is necessary to solve the problem of sterilizing the reaction vessel after cleaning in the existing technology.
[0004] Therefore, those skilled in the art have provided a coffee enzymatic fermentation reactor to solve the problems mentioned in the background art. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides:
[0006] A coffee enzymatic fermentation reactor includes: a reactor body; the reactor body is equipped with a cleaning and sterilization structure for ultraviolet sterilization after cleaning the interior of the reactor body.
[0007] The cleaning and sterilization structure includes a vertical frame that is fixed to the reactor body as a whole, and a servo motor is fixedly mounted on the top of the vertical frame. A vertical screw is mounted on the output end of the servo motor, and a screw plate frame that is spirally driven on the outside of the vertical screw and is movably and sealed to the reactor body.
[0008] The inner side of the vertical frame is equipped with ultraviolet germicidal lamps arranged in a ring at equal intervals, which are sealed and movable with the reaction vessel body.
[0009] Preferably, the reactor body is equipped with a stirring structure for stirring coffee enzymes.

[0014] An inner scraper is fixedly attached to the inside of the reactor body between the bottom shaft frame and the transmission frame.
[0015] Preferably, an inner stirring plate is rotatably provided on the inner side of the outer stirring frame.
[0016] The inner stirring plate is used to rotate inside the outer stirring frame in response to the resistance of the coffee enzymatic fermentation raw materials.
[0017] Preferably, a spur gear ring is fixedly attached to the outer edge of the bottom shaft frame, and the spur gear ring meshes with a spur gear, with a servo motor connected to the center of the spur gear.
[0018] The second servo motor is fixedly mounted on the inner wall of the vertical frame;
[0019] The bottom of the reactor body is provided with a feeding hopper fixed to the bottom wall of the vertical frame;

[0022] The front side of the reactor body is equipped with a feeding pipe for feeding raw materials for coffee enzymatic fermentation.
[0023] The technical effects and advantages of this utility model are as follows:
[0024] This invention utilizes a servo motor to drive a spur gear and a spur gear ring, which in turn rotates the stirring rod and the outer stirring frame, thus stirring the coffee enzymatic fermentation raw materials inside the reactor. This transmission method ensures stable and efficient operation of the stirring rod, allowing the coffee enzymatic fermentation raw materials to mix thoroughly. This promotes uniform enzymatic fermentation, improving fermentation efficiency and product quality.
[0025] This invention, while the stirring rod rotates, drives the inner scraper to rotate along the inner wall of the reactor, effectively scraping away residual coffee enzyme fermentation materials from the reactor's inner wall. This prevents the accumulation of residual materials from affecting subsequent fermentation processes, avoids cross-contamination between different batches of materials, and ensures the purity of raw materials and the cleanliness of the fermentation environment for each fermentation process.
[0026] In this invention, after the reactor body is processed and cleaned, a servo motor is activated to drive the vertical screw to rotate, causing the ultraviolet germicidal lamp on the screw plate frame to move into the reactor body for sterilization. The ultraviolet germicidal lamp can effectively kill residual bacteria and microorganisms inside the reactor body, reducing the risk of contamination during the next batch of coffee enzymatic fermentation, ensuring product hygiene and safety, and extending the product's shelf life.

[0039] For examples, please refer to Figures 1-5 In this embodiment, a coffee enzymatic fermentation reactor is provided, including: a reactor body 1; the reactor body 1 is equipped with a cleaning and sterilization structure 2 for ultraviolet sterilization after cleaning the interior of the reactor body 1;
[0040] The cleaning and sterilization structure 2 includes a vertical frame 201 that is integrally fixed to the reactor body 1. A servo motor 202 is fixedly mounted at the top of the vertical frame 201. A vertical screw 205 is mounted at the output end of the servo motor 202. A screw plate frame 203 is provided on the outer side of the vertical screw 205 and is movably and sealed to the reactor body 1. Ultraviolet germicidal lamps 204 are movably and sealed to the reactor body 1 and are arranged in a ring at equal intervals on the inner side of the vertical frame 201.
[0041] The inner side of the reaction vessel body 1 is equipped with a transmission stirring structure 4 for stirring coffee enzymes. The transmission stirring structure 4 includes a transmission frame 401 rotatably disposed inside the reaction vessel body 1, and a bottom shaft frame 403 that is sealed and rotatably located at the bottom end of the transmission frame 401.
[0042] A ring shaft is rotatably and sealed between the bottom shaft frame 403 and the reactor body 1. Several feeding troughs for coffee enzymatic fermentation are opened on the inner side of the bottom shaft frame 403. A stirring rod 404 located at the center of the reactor body 1 is fixedly installed at the center of the bottom shaft frame 403, and a stirring frame 405 for stirring during coffee enzymatic fermentation inside the reactor body 1 is fixed to the outer wall of the stirring rod 404.
[0043] An inner scraper 402, which is tightly attached to the inside of the reactor body 1, is integrally fixed between the bottom shaft frame 403 and the transmission frame 401. An inner stirring plate 406 is rotatably mounted on the inside of the stirring outer frame 405.
[0044] The inner stirring plate 406 is used to rotate inside the outer stirring frame 405 in response to the resistance of the coffee enzymatic fermentation raw materials. A spur gear ring 407 is integrally fixed to the outer edge of the bottom shaft frame 403, and the spur gear ring 407 meshes with a spur gear 408. A servo motor 409 is connected to the center of the spur gear 408.
[0045] The servo motor 409 is fixedly mounted on the inner wall of the vertical frame 201; the bottom end of the reactor body 1 is provided with a feeding hopper 3 fixed to the bottom wall of the vertical frame 201; the feeding hopper 3 and the bottom shaft frame 403 are connected by a rotating and sealed assembly via a ring shaft.
