And the number of turns of the spiral part of the control groove 676 is the same as the number of rotatable turns of a single baffle 674. A control ball 677 is fixedly connected to the outer wall of the rotating rod 65. The diameter of the control ball 677 fits the width of the spiral part of the control groove 676.

[0047] Refer to Figure 1 , Figure 2 And Figure 8, a feeding hopper 8 is fixedly connected to the upper part of the cylinder body 1. The inside of the feeding hopper 8 is communicated with the inside of the cylinder body 1. The shape of the feeding hopper 8 is a hollow frustum of a cone, and the diameter of the top end of the feeding hopper 8 is larger than that of the bottom end. A water storage ring 9 is fixedly connected to the outer wall of the cylinder body 1, a heating ring 10 is fixedly connected to the outer wall of the water storage ring 9, a heating pipe 11 is arranged inside the heating ring 10, a support 12 is fixedly connected to the outer wall of the cylinder body 1, the bottom end of the support 12 is fixedly connected to a bottom plate 13, and a marking line is arranged at the top end of the bottom plate 13 at the same vertical position as the bottom end of the blanking bin 3. Through the setting of the marking line, it is ensured that the staff can conveniently place the container for receiving materials at the position in the same vertical area as the bottom end of the blanking bin 3.

[0048] Working principle: When in use, the staff first put an appropriate amount of cocoa butter and the color powder ground from the dried flowers to be extracted with pigments into the stirring chamber 2 through the feeding hopper 8, then add water into the water storage ring 9, then start the equipment, and adjust the heating pipe 11 to an appropriate temperature, so that the heating pipe 11 heats the water body, and the water body heats the outer wall of the cylinder body 1, so as to ensure that different positions of the outer wall of the cylinder body 1 are evenly heated.

[0049] At the same time, at this time, the output shaft of the motor 64 drives the rotating rod 65 to rotate, so that the rotating rod 65 drives the stirring blade 66 to rotate, so that the flow rate of the cocoa butter and the color powder can be increased, and the speed of obtaining pigments can be accelerated. At the same time, during the rotation of the stirring blade 66, the scraping plate 68 is driven to rotate, so that the cocoa butter adhered to the inner wall of the cylinder body 1 can be scraped off.

[0050] During the mixing process, the staff rotates the second gear 57, so that the second gear 57 drives the first gear 56 to rotate, so that the first gear 56 drives the turntable 51 to rotate. And during the rotation process, the staff observes the marks on the outside of the turntable 51 through the observation slot 510. When the mark rotates to the required sieve hole size, the staff stops rotating the second gear 57.

[0051] At the same time, during the rotation of the turntable 51, when the turntable 51 is subjected to an external force, the turntable 51 drives the insert block 582 to rotate under the action of the rotational force. Thus, after the spherical surface of the insert block 582 is stressed, the insert block 582 is pushed, so that the insert block 582 enters the inside of the moving groove 581. Until the insert block 582 moves to the vertical area where the next slot 584 is located, the insert block 582 can enter the inside of the slot 584 under the elastic force of the spring 583. So that when the turntable 51 rotates to the vertical area where the mounting plate 53 is in the same vertical area as the bottom end of the blanking bin 3, the staff can obviously feel that it is more difficult to rotate the second gear 57. Therefore, the staff can ensure that the turntable 51 rotates to an appropriate position by the difficulty of rotating the second gear 57.

[0052] After the cocoa butter and the color powder are mixed, the staff first turn off the motor 64, place the container for receiving the material at the position on the bottom plate 13 where the marked area is set, and then rotate the threaded rod 63. As a result, the threaded rod 63 moves downward during rotation and pushes the slide plate 62 downward, so that the motor 64 moves downward and drives the rotating rod 65 downward, so that the rotating rod 65 enters the control groove 676, so that the control ball 677 also enters the control groove 676. As a result, during the downward movement of the control ball 677, it forces the rotating block 673 to rotate to an area where the control groove 676 is in the same vertical position as the control ball 677, driving the rotating block 673 to rotate, so that the rotating block 673 and the material outlet 671 are in different vertical positions, so that the cocoa butter and color powder mixture flows into the material storage bin 3 through the material outlet 671 and passes through the fine sieve 54 into the receiving container.

[0053] After the material receiving is completed, the staff replace the container, then take out the insertion rod 586 from the storage box 585, insert the insertion rod 586 into the insertion hole 59, and then rotate the insertion rod 586, so that the rotating shaft 52 rotates 180 degrees, so that the turntable 51 rotates 180 degrees. At this time, the staff can access the material on the fine sieve 54.

[0054] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
