Description
Technical Field
[0001] The invention particularly relates to a dough kneading device for producing bread with medicinal and edible properties, belonging to the technical field of bread production and dough kneading. Background Art
[0002] As a functional food, the production of medicinal and edible bread sets higher standards for dough kneading technology. This type of product usually adds a variety of medicinal and edible ingredients such as yam, poria cocos, and tangerine peel. These ingredients have special physical and chemical properties and require more refined dough kneading. The addition of medicinal and edible ingredients significantly changes the rheological properties of the dough. The water absorption of many Chinese medicinal material powders is much higher than that of ordinary flour, and the water absorption properties of different medicinal materials vary greatly.
[0003] At present, the friction heat generated by traditional dough kneading devices during the stirring process is difficult to precisely control. The active substances in edible and medicinal ingredients (such as polysaccharides, flavonoids, etc.) are extremely sensitive to temperature. Local overheating (40°C) may cause these active ingredients to become inactivated, reducing the health benefits of the product. Summary of the Invention

This design can control the temperature gradient of the barrel wall within ±1.5°C, effectively avoid local overheating, and effectively improve the health care effect of the product. The fan is integrated in the exhaust pipe to form an axial airflow to promptly take away the waste heat generated by the hot end of the refrigeration plate. The maze structure design of the protective shell not only protects the refrigeration elements but also guides the airflow path to ensure the continuous and efficient operation of the refrigeration system.

The labyrinth structure design of the protective shell 23 not only protects the refrigeration components but also guides the airflow path to ensure that the refrigeration system continues to operate efficiently.
[0022] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a dough kneading device for producing bread with medicinal and edible properties; A support plate 2 is provided at the top of the base frame 1, and a threaded rod 3 is rotatably provided on the back of the support plate 2. A No. 1 motor 4 is provided at the top of the support plate 2, wherein the bottom end of the output shaft of the No. 1 motor 4 is connected to the top end of the threaded rod 3, and a lifting plate 5 is provided through the outer thread of the threaded rod 3, and a combination cover 6 is provided at the bottom end of the lifting plate 5, wherein the combination cover 6 is located above the dough barrel 19.
[0023] The base frame 1 is the main supporting component at the bottom end of the dough kneading device for the production of medicinal and edible bread. The support plate 2 is used to provide installation support for the threaded rod 3 and the No. 1 motor 4, and a through groove is opened inside the support plate 2. A guide rod is provided inside the through groove, wherein the guide rod movably passes through the interior of the lifting plate 5 and is driven by the No. 1 motor 4.

When the rotating shaft 12 drives the stirring rod 14, the spiral blade 15 and the scraper 13 to be inserted into the dough kneading barrel 19, the bottom end of the combination cover 6 can contact the top of the dough kneading barrel 19. The combination cover 6 can be used to cover the top of the dough kneading barrel 19 to prevent flour from splashing during kneading.
[0024] See also Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, a dough kneading device for producing bread with medicinal and edible properties; The stirring mechanism includes a cleaning component and a quick-release component. The cleaning component includes a scraper 13, wherein the inner side of the scraper 13 is arc-shaped. The quick-release component includes a positioning rod 11 and a spring 10. The top of the lifting plate 5 is provided with a No. 2 motor 7, and the output end of the No. 2 motor 7 is provided with an assembly block 8. The outside of the assembly block 8 is provided with an assembly shell 9, wherein two groups of springs 10 are provided on the outside of the assembly shell 9, and the inner side of the positioning rod 11 is connected to one end of the two groups of springs 10. The positioning rod 11 is designed to be "T"-shaped, wherein the positioning rod 11 passes through the assembly shell 9 and is inserted into the assembly block 8. The bottom end of the assembly shell 9 is provided with a rotating shaft 12, and the scraper 13 is provided on the outside of the rotating shaft 12. A plurality of stirring rods 14 are provided at equal intervals above and below the outside of the rotating shaft 12, and a spiral blade 15 is provided on the outside of the rotating shaft 12 relative to the bottom of the stirring rod 14.
[0025] The cleaning component's curved scraper 13 (PTFE-coated, with a friction coefficient of 0.05) maintains a clearance of 0.5 to 1 mm with the inner wall of the dough mixing drum 19. This dynamic contact is driven by the rotating shaft 12, effectively reducing the amount of flour remaining on the inner wall of the dough mixing drum 19. This design reduces the raw material adhesion rate from 8% in conventional equipment to 1.2% without generating metal friction heat. Driven by the second motor 7, the rotating shaft 12 can be driven to rotate, and the flour and water inside the dough mixing barrel 19 can be pushed upward by the spiral blades 15. The pushed flour can be stirred and mixed by the multiple sets of stirring rods 14, thereby achieving the dough processing of the flour in the dough mixing barrel 19; A T-shaped positioning rod 11 structure pre-tightened by a spring 10 is adopted. When the positioning rod 11 passes through the assembly shell 9 and is inserted into the assembly block 8, the assembly shell 9 and the assembly block 8 can be quickly locked. This modular design facilitates the replacement of stirring rods 14 (paddle type / hook type) and spiral blades 15 of different shapes to adapt to the rheological properties requirements of different medicine and food formulas.
[0026] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, a dough kneading device for producing bread with medicinal and edible properties; The weighing mechanism includes pressure sensors 16, four groups of pressure sensors 16 are arranged at the top of the base frame 1, a support frame 17 is provided at the top of the four groups of pressure sensors 16, a dough barrel 19 is rotatably arranged inside the support frame 17, and a drive assembly 18 is provided on one side of the support frame 17, and the drive assembly 18 includes a drive motor and gears.
[0027] The weighing mechanism composed of four groups of pressure sensors 16 monitors the changes in the material quality in the dough barrel 19 in real time through the support frame 17. The data is fed back to the control system to automatically adjust the amount of water added, solving the problem of large differences in water absorption of Chinese medicinal materials. When the dough barrel 19 needs to be kneaded into dough, the servo motor of the drive component 18 adjusts the angle of the dough barrel 19 through gear transmission (the telescopic tube 28 can be stretched and extended to adapt to the angle adjustment of the dough barrel 19), which is convenient for the later kneading of the dough inside the dough barrel 19.
[0028] Working principle: When the No. 2 motor 7 drives the rotating shaft 12 to operate, the temperature control mechanism starts synchronously, and the liquid circulation component maintains the low temperature environment of the barrel. At the same time, the stirring mechanism forms a laminar-turbulent alternating mixed flow field through the optimized design of the stirring rod 14 and the spiral blade 15 (lead ratio 1:1.5). When the temperature sensor detects that the local temperature rise exceeds the threshold, the control system automatically reduces the speed and increases the refrigeration power to ensure that the active ingredients of medicinal and edible origin are kept in the safe temperature range of 28±2℃.
