Description

Technical Field

[0001] The utility model relates to the technical field of flour processing, in particular to a stone-ground flour grading and screening device. Background Art

[0002] Stone-ground flour is a traditional flour processing method, which is obtained by grinding grains with stone mills. Unlike industrially processed mechanical milling, stone-ground flour retains the bran and germ in the grains, while maintaining the original flavor and nutritional value of the grains.

[0003] Since the uniformity of the particle size cannot be controlled during the stone mill grinding process, the flour needs to be graded and screened to distinguish the grades of the flour. The existing stone mill flour grading and screening generally adopts a multi-stage screening structure. First, the coarsely ground flour enters the first-stage screen, and the larger flour particles will be screened out. Then, the flour that passes through the first-stage screen continues to enter the next-level screen, and through the continuous screening process, flour products of different particle sizes are obtained.

[0004] The disadvantage of the stone-ground flour grading and screening device is that the screened flour remains above the screen, which makes it difficult to quickly discharge the flour. At the same time, the screen is easily blocked after long-term use, and the existing grading and screening device is not convenient to clean. Utility Model Content

[0005] The technical problem to be solved by the utility model is to solve the above problems and provide a stone-milled flour grading and screening device which is convenient for discharging and cleaning.

[0007] As an improvement, the inner wall of the bottom of the screening box is inclined downward toward the right side.

[0008] As an improvement, the height of the baffle is equal to the height of the screening box, and the front-to-back width of the baffle is equal to the front-to-back width of the screening box.

[0009] As an improvement, the lower right end of the screening box is provided with front and rear opposite internal threaded blind holes, and the side wall of the baffle is rotatably plugged with a limiting bolt that cooperates with the internal threaded blind hole.

[0010] As an improvement, the aperture of the screen decreases from top to bottom.

[0011] As an improvement, the screen includes a mesh plate located in the screening box and an insert block located in the slot, the height of the insert block is greater than the height of the mesh plate, and the upper ends of the left and right side walls of the screen are provided with vertical plates that are attached to the front and rear inner walls of the screening box.

[0012] As an improvement, the upper end of the vertical plate is inclined downward toward the center of the screen.

[0013] The advantages of the utility model compared with the prior art are:

[0014] 1. A detachable baffle is provided on the right side of the screening box, which can be disassembled after screening, so that the screen can be easily taken out for discharging, making the discharging operation convenient;

[0015] 2. Since the screen is easy to disassemble, it can be easily cleaned to ensure the screening effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS
