Convection dryers vary greatly in size, features and delivery method and design of the air and heat distribution. To meet your process requirements efficiently, it is important to select the right type of dryer for your products and processes. It is equally important, however, to properly size and design the dryer.
One of the most crucial aspects of the overall health of an industrial heater is its insulation resistance, which can be affected by many factors. Faulty elements, age, moisture ingress and long periods of downtime can all negatively impact the health of an industrial heater.
Manufactured (or synthetic) polymers were introduced in the 1800s, and since then, they have contributed significantly to our quality of life. Many products we rely on daily would not be possible without plastics, and those that would be possible without plastics have been vastly improved with plastics.
Rotary-drum dryer design resolves problems with inconsistent feedstocks. The dryers can process green biomass — used for co-firing with biomass applications — to a material of uniform moisture content.
Uniformly drying a non-uniform product is difficult. Decreasing the drying time of heat-sensitive products is challenging. One example is a three-dimensional product saturated with water — for instance, molded-fiber packaging products.
Controlled drying parameters ensure that a food or feed product is shelf-stable, removing a precise amount of moisture. Yet a single processing deviation can affect batch specifications, requiring an operator to overdry to compensate.
Two models, DewMaster and PDM75, are offered with the company’s X3 high performance chilled mirror moisture sensor. The sensor is a drift-free, primary method device with certification traceable to NIST.
If you have a rotary biomass dryer, chances are you have dealt with the three most common problems in biomass rotary dryer systems: rocks, fires and explosions, and nonuniform moisture content in final product. Get advice on dealing with all three.
