The product has a large moisture content in filter cake of mycelial fermentation broth, and can not be dried by other airflow drying methods. Based on the basic type of air dryer, a set of strengthening dryer with stepless speed adjustment is added to make the product wet. The material enters the fortifier dryer through a screw feeder and is thoroughly mixed with the hot gas stream. The material is broken into granules by the crushing and advancement of a rapidly rotating knife, moving toward the outlet while drying, and finally entering the drying tube under the suction of the wind, and further drying evenly. Wet and heavy particles that cannot be attracted by the wind continue to be crushed and dried until they can be sucked into the drying tube by the wind. This product is more efficient than other air dryers, and the residence time of the material in the drying tube is short, and the best dried product can be obtained.
Sodium Hexametaphosphate (NaPO3)6,white powder-like crystal or transparent glassy crystal, density is 2.484(20),easily soluble in water,but not in organic solution,absorbent to dampness,and turn sticky when absorbed dampness in air.it is possible to form solvent compound with metallic ions such as Ca,Ba,Mg,cu andfe;it is affine agent for Water Treatment.
Sodium hexametaphosphate (SHMP) is a hexamer of composition (NaPO3)6.Sodium hexametaphosphate of commerce is typically a mixture of polymeric metaphosphates, of which the hexamer is one, and is usually the compound referred to by this name. Such a mixture is more correctly termed sodium polymetaphosphate.
SHMP is used as a sequestrant and has applications within a wide variety of industries, including as a food additive in which it is used under the E number E452i. Sodium carbonate is sometimes added to SHMP to raise the pH to 8.0–8.6, which produces a number of SHMP products used for water softening and detergents.
A significant use for sodium hexametaphosphate is as a deflocculant in the production of clay-based ceramic particles.It is also used as a dispersing agent to break down clay and other soil types for soil texture assessment.
It is used as an active ingredient in toothpastes as an anti-staining and tartar prevention ingredient.
As a food additive, SHMP is used as an emulsifier. Artificial maple syrup, canned milk, cheese powders and dips, imitation cheese, whipped topping, packaged egg whites, roast beef, fish fillets, fruit jelly, frozen desserts, salad dressing, herring, breakfast cereal, ice cream, beer, and bottled beverages, among other foods, can contain SHMP.
