Description

A rapid sampling device for flour detection

technical field

The invention relates to the technical field of flour detection, in particular to a rapid sampling device for flour detection.

Background technique

Flour is a powder made from wheat. According to the protein content in flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. The grade of flour is also directly related to the content of minerals (ash) in the outer skin and germ of the wheat kernel. The higher the content of the substance, the lower the grade of the flour; conversely, the less it is, the higher the grade of the flour. If you pursue the unique flavor of flour in bread, low-grade flour is more suitable than high-grade flour. For example, healthy whole-wheat bread is made from whole-wheat flour that contains bran. As far as general flour is concerned, its mineral content will not have much effect on the properties of its bread making. However, if the content of minerals in it is high, the color of the flour will be slightly gray, and the color of the bread will naturally be black and dark.

It is transported into the fan (14), and is transported into the filter box (4) through the second air duct (16), and the air is discharged from the inside of the filter box (4), and the impurities inside the filter box (4) are blown by the wind and discharged through The pipe (26) discharges the impurities, and then the fan (14) is turned off. At this time, the first solenoid valve on the surface of the powder conveying pipe (19) is opened, and the flour slides into the powder conveying pipe (19), and then the fan (14) is started in the reverse direction. , the air is drawn through the second air duct (16), the air is discharged through the first air duct (15), the air is drawn in through the filter box (4), the first filter is performed through the dust filter (25), and then the The second filter of the inclined filter screen (23), the dust is blocked by the inclined filter screen (23), and the air is transported to the inside of the first air duct (15); Step 3. At this time, the first air duct (15) blows air to the inner cavities of the telescopic pipe (13), the powder conveying pipe (19) and the powder discharging pipe (18) respectively, and the flour in the powder conveying pipe (19) is discharged. Provide thrust, the flour is blown into the sampling box (3), the remaining flour in the first air duct (15) is blown into the sliding cylinder (8) and the powder discharge duct (18) respectively, and the flour is re-delivered into the flour. Inside the processing facility (1); Step 4. Pull out the collection box (22) from the sampling box (3) by pulling the handle, take out the flour for testing, and then repeat steps 1 to 3, repeat the operation, sample the flour through the downward movement of the sliding cylinder, and then slide The drum is lifted up and pumped by the fan, and the sampled flour is transported to the collection box by the wind force, and the remaining flour can be quickly cleaned after the sampling is completed, so as to prevent the flour sampled last time from interfering with the next detection effect, and the detection is more Precise.
