When it comes to drying large amounts of raw material, there are a number of options for manufacturers to choose from, depending on their budget, space and properties of the material being dried. Industrial dryers are often used to remove moisture from materials such as powders, foods and chemicals for the pharmaceutical, paper, pollution control, food and agricultural industries. If your company is in the market for a new industrial dryer, there are 5 main types for different applications, each with its own advantages and disadvantages. Dryers that pass material through a large, revolving metal drum and heated by gas, liquid or solid fuel are commonly used in the chemical, food and mineral industries. Rotary dryers have low maintenance costs and allow vast amounts of material with differing particle sizes to dry at one time. However, because these dryers are powered by gas, moisture control is difficult and they often create fire hazards as a result of drying flammable materials. Because the drum is often quite large, these dryers often require a lot of space.
