Starch vacuum filter, also known as vacuum dehydrator.

Starch vacuum filter presses are used in the dehydration section of starch processing.

Starch vacuum filter, also known as vacuum dehydrator. The principle of a starch vacuum filter is to use a vacuum pump to create a negative pressure inside the filter. This creates a pressure difference between the inside and outside of the drum, allowing water and air to pass through the mesh while preventing starch granules from passing through, thus ensuring that the starch is fully adsorbed onto the surface. Once the pre-coating layer reaches 7-8mm, adjust the scraper and begin scraping off the wet starch. The moisture content of the wet starch is approximately 38%-40%.
