technical field

The utility model belongs to the field of starch production equipment, in particular to a high-efficiency air flotation machine with cleaning function.

Background technique

At present, in the production process of starch, especially corn starch, there are three main methods of concentration and extraction of corn gluten powder contained in gluten water: sedimentation method, gluten concentrator concentration and air flotation concentration method. Among them, the air flotation concentration method uses an air flotation tank plus a sedimentation tank for production. The main performance is to pump gluten water into one end of the air flotation tank, and move to the other end after the material fills the tank. During the movement, the gluten water The tiny protein particles in the gluten float up after being adsorbed by the air bubbles and aggregate into a block to move forward. During the migration process, the micro starch in the gluten water sinks due to its own gravity and is discharged through the bottom of the tank, and the concentrated gluten is discharged through the other end of the air flotation tank. .
