Rate, about difference 0.5~3.0%.When individual, due in drying process, by the shadow of drying system such as atomizer atomizing effect
It rings, there are partial block glue in the product that bottom of tower discharge port goes out, product moisture content is just far longer than cyclone separator bottom discharge mouth
The product gone out.
3, the product colour that the product and cyclone separator bottom discharge mouth that drying tower bottom discharge port goes out go out is variant, normally
In the case of, the product that drying tower bottom discharge port goes out is deeper than the product colour that cyclone separator bottom discharge mouth goes out.
4, the product that the product and cyclone separator bottom discharge mouth that drying tower bottom discharge port goes out go out is due to by product grain
The factors such as inconsistent, moisture content is inconsistent influence is spent, product packaging volume size non-uniform phenomenon is caused.
5, the product that the product and cyclone separator bottom discharge mouth that drying tower bottom discharge port goes out go out, through development department of company matter
Amount clinical laboratory is detected respectively, although product is all qualified, product quality technical indicator has differences, and it is uniform to product to influence client
The use demand of property.
