Grease filters for purification of liquor and beverage industry perlite filter aid

Perlite filter aid and the role of introduction: Perlite is acidic siliceous volcanic glass lava containing water of crystallization, is igneous rock. It particles at high temperature calcination process, rock crystal water evaporation, perlite 15-20 times the original volume ratio of rapid expansion, so rich in closed and open pores formed expanded perlite, and then carefully after grinding and winnowing, perlite filter aid is formed with special properties. Perlite filter aid is a white powder of amorphous vitreous inert particles, the main component of potassium, sodium and aluminum silicate, no smell, itself does not contain organic matter. Production process, perlite after heat treatment to achieve sterilization and eliminate the effect of organic matter, and therefore the solubility of perlite filter aid in inorganic and organic acids in extremely low chemical stability, will not affect the color of the liquid to be filtered , smell and taste. Each particle perlite filter aid is very irregular curly sheet with a porosity of 80-90% when the filter cake is formed, each particle has many pores interlinked, so you can quickly filtered, 0.1 micron size and capture particles. Perlite filter aid is widely used in beer, monosodium glutamate, beverages, sugar, citric acid, vegetable oil, petroleum, pharmaceutical, chemical products production filtration industry, is an ideal and reliable new industrial filter special inorganic dielectric material. The company's products meet national health standards, widely used in many industries as beer, wine, liquor, MSG, juice, corn syrup, spices and medicine, enzymes, biological work, petroleum, chemicals, fine chemicals, metallurgy, sewage treatment .
