Description

Technical Field

[0001] The utility model relates to the technical field of instant coffee mixing, in particular to an instant coffee mixing device. Background Art

[0002] With the development of society, instant coffee is becoming more and more popular. In the production process of instant coffee, the raw coffee beans are generally roasted and ground first, and then the aromatic liquid is extracted with water, and the remaining extract is used as the low-aroma extract. The aromatic liquid is separated by distillation to obtain aromatic liquid and low-aroma liquid components. The aromatic liquid is distilled and condensed to obtain concentrated aromatic liquid and aromatic liquid residue. The low-aroma liquid component and the low-aroma extract are mixed to obtain concentrated liquid. The aromatic liquid residue and the concentrated liquid are then combined and mixed to obtain concentrated coffee liquid, which is then spray-dried to obtain coffee dry powder, which is then mixed with the atomized concentrated aromatic liquid to obtain instant coffee. In the mixing process, an instant coffee mixing device is required.

[0003] For example, in the patent application with the authorization publication number CN220496068U and the authorization publication date 2024-02-20, entitled “A Double-cone High-efficiency Mixing Device for Instant Coffee”, the third rotating shaft is driven to rotate by starting the first motor, the third bevel gear is driven to rotate by rotating the third rotating shaft, the first bevel gear is driven to rotate by rotating the third bevel gear, the second bevel gear is driven to rotate by rotating the third bevel gear, the first rotating shaft is driven to rotate by rotating the first bevel gear, the transverse blades are driven to rotate by rotating the first rotating shaft, the second rotating shaft is driven to rotate by rotating the second bevel gear, the transverse blades are driven to rotate by rotating the second rotating shaft, and the longitudinal blades are driven to rotate by rotating the third rotating shaft, thereby achieving the technical problem of efficiently and fully mixing the materials to be mixed;

[0004] During the actual use of the above-mentioned device, multiple sets of rotating shafts are used to fully mix the materials. However, foam may be generated during the merging and mixing of the materials. The foam will occupy a certain space, reducing the contact area between the liquids, thereby affecting the mixing effect. In addition, the foam may entrain air into the product, affecting the stability and quality of the product.

[0005] So we have proposed an instant coffee mixing device to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of the utility model is to provide an instant coffee mixing device to solve the problems in the current market raised by the above background technology.

[0008] 2. Technical solution:

[0009] To achieve the above object, the utility model provides the following technical solution: an instant coffee mixing device, comprising a mixing barrel, a feeding pipe and a plurality of storage barrels are installed at the upper end of the mixing barrel, and a rotating shaft is installed on the bearing at the lower end of the middle part of the mixing barrel, and a mixing blade and a scraper assembly are installed on the rotating shaft;

[0010] The lower end of the material storage barrel is provided with a material discharge port, and a material blocking piece is slidably installed inside the material discharge port, and the lower part of the material blocking piece is slidably installed inside a fixing rod, and the fixing rod is fixedly installed on the inner wall of the upper end of the mixing barrel.

[0011] Furthermore, through holes are opened at equal intervals inside the mixing blades, spikes are evenly fixed on the mixing blades, and the mixing blades are distributed at equal angles on the rotating shaft.

[0012] Through the above technical solution, the mixing blades can improve the mixing effect through the through holes, and at the same time, the sharp thorns can be used to puncture the foam to reduce the impact of the foam.

[0013] Furthermore, the scraper assembly includes a connecting rod fixed on the rotating shaft, a scraper body is fixed to the end of the connecting rod, and the scraper body and the inner wall of the storage barrel are in contact with each other, and a driving block is fixed to the upper end of the connecting rod.

[0015] Furthermore, the blocking member includes a movable rod that slides up and down in the fixed rod, a blocking ball is fixed to the upper end of the movable rod, and a limiting plate is fixed to the middle of the movable rod, and the limiting plate is located above the fixed rod.

[0016] Through the above technical solution, the movable rod can drive the blocking ball to move up and down.

[0017] Furthermore, the diameter of the blocking ball is greater than the minimum diameter of the feed opening.

[0018] Through the above technical solution, the material discharge port can be blocked by the blocking ball.

[0019] Furthermore, the shortest distance from the bottom end of the movable rod to the fixed rod is greater than the shortest distance from the driving block to the fixed rod, the upper end surface of the driving block is designed as an arc structure, and the lower end of the movable rod is set as a hemisphere.

[0020] Through the above technical solution, the driving block can be pressed toward the movable rod.

[0021] 3. Beneficial effects:

[0022] By adopting the technical solution provided by the utility model, compared with the prior art, the instant coffee mixing device of the utility model can achieve uniform mixing of materials through the cooperation of the mixing blades and the scraper assembly, and can puncture the foam generated by the mixing of materials to reduce the impact of the foam. The specific contents are as follows:

[0023] First, one material is put into the mixing barrel from the feed pipe, and then the other materials are placed in the storage barrel. Then, the motor at the upper end of the rotating shaft is started, and the motor drives the rotating shaft to rotate, and the rotating shaft drives the mixing blades and the scraper assembly to rotate synchronously. During the rotation process, the mixing blades mix the materials evenly, and use the through holes opened inside the mixing blades to change the flow state of the materials, making the flow field more complex, further enhancing the mixing effect, and to a certain extent reducing the resistance of the mixing blades during the stirring process, reducing energy consumption, and at the same time using spikes to puncture the foam generated by the mixing of the materials to reduce the impact of the foam;

[0024] During the rotation of the scraper assembly, the scraper body is used to scrape off the material adhering to the mixing barrel to prevent the adhering material from affecting the mixing effect. At the same time, during the rotation of the driving block, the bottom end of the movable rod is squeezed, and the movable rod moves upward after being forced, driving the blocking ball to move upward synchronously, so that there is a gap between the blocking ball and the discharge port, and the material stored in the storage barrel can fall into the mixing barrel from the gap. When the driving block does not exert an extruding force on the movable rod, it moves downward under the action of gravity to block the discharge port. This process is repeated to achieve the slow addition of other materials during stirring to promote uniform mixing and reduce the generation of foam. BRIEF DESCRIPTION OF THE DRAWINGS
