Description

Technical Field

[0001] The utility model belongs to the technical field of baking soda powder manufacturing, in particular to a baking soda powder particle screening device. Background Art

[0002] Baking soda, also known as sodium bicarbonate powder, is a chemical. It is a white crystalline powder that is odorless and salty in taste. It decomposes slowly in humid air. When the aqueous solution is left for a long time or heated, it produces carbon dioxide gas to form sodium carbonate, and the alkalinity is enhanced. Baking soda is solid, round, white in color, and easily soluble in water. During the production process of baking soda, large particles in the baking soda need to be screened out through a screening device, and only baking soda with qualified particles can be used.

[0003] When using the existing baking soda powder particle screening device, usually a screening net is directly used to directly screen the baking soda powder. However, after a large amount of baking soda powder is put in, it is easy to directly cause the screening net to be blocked, thereby reducing the screening speed of the baking soda powder and affecting the working efficiency of the screening device. For this reason, we propose a baking soda powder particle screening device. Utility Model Content
