Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and particularly relates to a dough flour brushing machine. Background Art

[0002] During the dough kneading process, in order to prevent the dough from being overly sticky, the maker often sprinkles some flour. However, when the dough is kneaded until it is smooth and elastic, if the excess flour remains on the surface of the dough, it may form an uneven surface layer during the fermentation or baking process, affecting the appearance of the bread or pastry. Therefore, this excess flour needs to be removed. Flour brushing can help remove the excess flour on the surface of the dough, making the dough look cleaner and smoother.

[0003] In the prior art, the task of removing the excess flour on the surface of the dough usually relies on manual labor, which is completed by gently brushing with a soft brush held by hand. However, in the automated production process of pastry products, the dough appears continuously in a long strip shape. At this time, relying on manual flour brushing is not only inefficient but also the flour brushing effect is not satisfactory. Summary of the Invention

[0004] The purpose of the present invention is to provide a dough flour brushing machine that can achieve automatic operation of dough flour brushing, effectively improving the flour brushing efficiency and flour brushing effect.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A dough flour brushing machine includes a frame. Feed belts and discharge belts are respectively arranged at both ends of the frame. The feed belt and the discharge belt are arranged collinearly. A flour brushing mechanism is arranged between the feed belt and the discharge belt. The flour brushing mechanism includes an upper flour brushing component close to the feed belt and a lower flour brushing component close to the discharge belt. A first material receiving frame is arranged below the upper flour brushing component, and a second material receiving frame is arranged below the lower flour brushing component. The first material receiving frame and the second material receiving frame are symmetrically arranged. Openings are arranged at the opposite ends of the first material receiving frame and the second material receiving frame. A flour box is arranged on the frame, and the flour box is located below the openings of the first material receiving frame and the second material receiving frame.

[0006] By adopting the above technical solutions, the long strip dough is fed into the flour brushing mechanism through the feed belt, passes through the upper flour brushing component and the lower flour brushing component in sequence, and then is sent out through the discharge belt. The upper flour brushing component brushes the top of the dough, and the lower flour brushing component brushes the bottom of the dough, thereby automatically removing the excess flour on the surface of the dough. The brushed-off flour falls into the first material receiving frame and the second material receiving frame respectively, and the flour falls into the flour box below through the openings of the first material receiving frame and the second material receiving frame, completing the collection of the excess flour, effectively improving the flour brushing efficiency and flour brushing effect.

[0007] A further setting of the present invention is that a supporting plate is arranged between the upper powder brushing assembly and the lower powder brushing assembly.

[0019] The further setting of the present invention is that a coating for reducing friction is wrapped on the outer wall of the concentrating rod.

[0020] By adopting the above technical solution, during the movement of the dough, the coating can effectively reduce the friction between the dough and the concentrating rod.

[0021] The further setting of the present invention is that the first brush and the second brush are respectively located above and below the supporting plate.

After passing through the upper dusting assembly and the lower dusting assembly in sequence, they are sent out through the discharging belt. The upper dusting assembly dusts the tops of the dough pieces, and the lower dusting assembly dusts the bottoms of the dough pieces, thereby automatically removing the excess flour on the surface of the dough. The dusted flour falls into the first material receiving frame and the second material receiving frame respectively.

[0027] 3. When the flour in the first material receiving frame and the second material receiving frame falls into the flour box, it first passes through the sieve, screening out large dough pieces and impurities in the flour. The screened flour will fall into the flour box for collection; the second rotating shaft rotates, controlling the rotation of the rotating rod through belt drive, and then making the cam rotate. With the cooperation of the spring at the other end of the sieve, the sieve reciprocates horizontally, thereby improving the screening effect of the sieve. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Further, a concentrating assembly is arranged on the supporting plate 11. The concentrating assembly includes concentrating rods 13 symmetrically arranged on the supporting plate 11. The concentrating rods 13 are inclined towards the center of the supporting plate 11. When two dough pieces are finished being dusted by the upper dusting assembly 4 and enter the supporting plate 11, the concentrating rods 13 make the two dough pieces temporarily approach each other, facilitating the dusting operation of the lower dusting assembly 5 on the bottoms of the two dough pieces.
