Application of Citric Acid Industry
Abstract
Plate and frame filter or vacuum drum filter is generally used for citric acid filtration of fermentation broth. The crude diatomite filter aid produced by Daguan Diatomite Company can retain impurities such as black and polymer colloids.
Plate and frame filter is generally used for citric acid filtration after acid hydrolysis, and pre-coated crude products ensure its permeability and intercept CaSO.4Impurities such as sediment, polymer colloid and polysaccharide.
In the fine filtration of concentrated citric acid liquid, a closed pressurized vibrating leaf filter is generally used to mix coarse, medium and fine products and pre-coat them in different times. It can filter out impurities such as aconitic acid, denatured colloid, high molecular protein and pigment to obtain high purity citric acid solution.
