Description

Technical Field

[0001] This utility model relates to the technical field of powder product processing equipment, specifically to a dough kneading device for producing powder products. Background Technology

[0002] In the production of powder products, the process involves steps such as mixing, conveying, blending, and molding. To improve production efficiency and reduce labor intensity, the existing mixing process is basically automated using machinery and equipment, thereby effectively improving production efficiency.

[0003] Common existing dough mixing equipment includes vacuum dough mixers and twin-helix dough mixers. Vacuum dough mixers mix dough under negative pressure, which helps the dough absorb water, resulting in a better texture and thus a better-tasting product, making them very popular. However, existing vacuum dough mixers are all manually operated, and the process requires time for dough mixing. Therefore, the dough produced is not continuous, and they cannot be well integrated with downstream automated equipment, which causes inconvenience to the continuous and stable production of products.

[0004] Therefore, in order to overcome the above-mentioned technical problems, this utility model adds a double helix dough mixer to the rear end of the vacuum dough mixer and makes technical modifications to the double helix dough mixer, so that the entire dough mixing and production process can run continuously and stably, which is of great significance for ensuring product quality and improving production efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the existing technology by providing a dough mixing device for the production of powder products, thereby solving the problem that the dough produced by existing vacuum dough mixers and manual feeding cannot be continuously and stably connected to the downstream extruder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dough mixing equipment for producing powder products, including a vacuum dough mixer, a belt conveyor, and a double spiral dough mixer. The vacuum dough mixer is located at one end of the belt conveyor, and the other end of the belt conveyor is connected to one end of the double spiral dough mixer. A discharge port is provided at the bottom of the other end of the double spiral dough mixer, and a discharge spiral conveyor is installed below the discharge port.

[0007] Furthermore, there are at least two vacuum dough mixers arranged on one or both sides of the belt conveyor, with the outlet of the vacuum dough mixer located above the belt conveyor.

[0008] Furthermore, the double-helix dough mixer includes a dough mixing chamber, with a partition at the center of the bottom of the dough mixing chamber dividing it into a first dough mixing chamber and a second dough mixing chamber. The cross-section of the bottom of both the first and second dough mixing chambers is semi-circular, and the upper parts of the first and second dough mixing chambers are connected. A first auger is installed in the first dough mixing chamber, and a second auger is installed in the second dough mixing chamber.

[0009] Furthermore, the first auger is connected to the first motor reducer, and the second auger is connected to the second motor reducer.

[0010] Furthermore, the first motor reducer and the second motor reducer are located below the belt conveyor in spatial position.

[0011] Furthermore, a first discharge pressure plate is provided at one end of the first auger, and a second discharge pressure plate is provided at one end of the second auger. Both the first and second discharge pressure plates are located above the discharge port.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model continuously conveys the dough kneaded by the vacuum dough mixer to the extruder at the rear end through the double spiral dough mixer, realizing a continuous supply of materials to the extruder and playing a positive and beneficial role in ensuring the continuous and stable operation of production.

[0014] 2. This utility model uses a vacuum dough mixer to knead the dough, and then transports the kneaded dough to a double-helix dough mixer. The two-stage kneading process can more effectively ensure the quality of the dough and plays a positive role in ensuring product quality.

[0015] 3. This utility model has a discharge port at the bottom of the double spiral dough mixer and a discharge spiral conveyor below the discharge port. In this way, the dough in the double spiral dough mixer can be continuously and stably conveyed to the rear end, ensuring continuous and stable production. A discharge pressure plate is set on the discharge port. Through the action of the discharge pressure plate and the spiral, the dough can be smoothly and stably discharged, which promotes stable production. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1-3 As shown in Figure 5, in this embodiment, a belt conveyor 3 is provided. A first vacuum dough mixer 1 and a second vacuum dough mixer 2 are respectively provided on both sides of one end of the belt conveyor 3. The outlets of the second vacuum dough mixer 2 and the second vacuum dough mixer 2 are both located above the belt conveyor 3. At the other end of the belt conveyor 3, a double spiral dough mixer 4 is used in conjunction.

[0026] The double helix dough mixer 4 is provided with a dough mixing chamber. A partition 43 is provided in the middle of the dough mixing chamber. The partition 43 divides the dough mixing chamber into a first dough mixing chamber 41 and a second dough mixing chamber 42. The bottom cross-section of the first dough mixing chamber 41 and the second dough mixing chamber 42 are both semi-circular. The upper parts of the first dough mixing chamber 41 and the second dough mixing chamber 42 are connected.

[0027] A first auger 44 and a second auger 45 are respectively installed in the first dough mixing chamber 41 and the second dough mixing chamber 42. The first auger 44 is driven by the first motor reducer 442, and the second auger 45 is driven by the second motor reducer 452. A discharge port 47 is provided at the bottom of the other end of the dough mixing chamber corresponding to the belt conveyor 3. A first discharge pressure plate 441 is installed on the first auger 44, and a second discharge pressure plate 451 is installed on the second auger 45. Both the first discharge pressure plate 441 and the second discharge pressure plate 451 are located above the discharge port 47. A discharge screw conveyor 46 is installed below the discharge port 47.

[0028] Example 2

[0029] like Figure 4 As shown, in this embodiment, the first vacuum dough mixer 1 and the second vacuum dough mixer 2 are arranged and installed on one side of the belt conveyor 3. The rest is the same as in embodiment 1, so it will not be described again.

[0030] The principle of this utility model is as follows:

[0031] This invention enables continuous production. The process employs two vacuum dough mixers that work together. While one mixer is kneading the dough, the other is handling the discharging and feeding of the dough (the vacuum dough mixer is a mature existing equipment, and this process is manually operated, so it will not be described in detail). This cycle repeats continuously, ensuring continuous and stable production and effectively improving production efficiency.

[0032] The dough kneaded by the vacuum dough mixer is conveyed or lifted by the belt conveyor 3 to the double spiral dough mixer 4. At this time, the operator can further adjust the dough according to its actual condition through the double spiral dough mixer 4. During the operation of the double spiral dough mixer 4, the rotation direction of the first auger 44 and the second auger 45 can be adjusted in a timely manner by the on-site operator according to the actual production situation, such as the two augers rotating clockwise at the same time, rotating counterclockwise at the same time, or rotating in different directions, so as to ensure the quality of the dough. It should be noted that the discharge screw conveyor 46 is not started during this process.

[0033] After the double-spiral dough mixer 4 has finished mixing the dough, the first auger 44 and the second auger 45 rotate in the same direction and push the dough above the discharge port 47. At this time, the discharge screw conveyor 46 starts. Under the action of the first discharge pressure plate 441 and the second discharge pressure plate 451, the dough pushed above the discharge port 47 is continuously squeezed into the discharge port 47, and then transported to the extruder at the rear end by the discharge screw conveyor 46 to realize the preparation of powder products.

[0034] In the actual production application of this utility model, the dough mixing step is mainly completed by the vacuum dough mixer. The double helix dough mixer 4 is used to adjust the quality of the dough, but this is not the main function of the double helix dough mixer 4. The double helix dough mixer 4 mainly serves as a connection between the vacuum dough mixer and the downstream extruder. This utility model solves the problem of traditional vacuum dough mixers being unable to effectively connect with the extruder due to manual operation, thus affecting continuous production, by technically modifying the double helix dough mixer 4.
