Question 1

RATES

Accepted Answer

PolyClean’s mobile dryer quickly eliminates moisture from your pellets. At rates between 500 and 2000 pounds per hour (depending on material), we bring your resin to spec fast. You won’t have to worry about sending off wet material and – because we come to you – there’s very little hassle. Your convenience is important to us. We’ll even keep it inline, or box to box, so you don’t have to stop moving.

Question 2

MORE DETAILS

Accepted Answer

Our dryers have two systems. One is a closed loop, hot air drying system (see diagram below). In it, desiccant-dried air adjusts to -50 dew point. The other is a desiccant drying system. This dryer features a pair of four desiccant bed, 750 CFM dryers hooked up to six stainless steel hoppers with a capacity of 1000 pounds apiece. Two beds heat at all times, while two regenerate. Microprocessors control the whole operation.
 
Temperatures in the dryers range from 150 to 350 degrees Fahrenheit. Each hopper has individual temperature controls.

Question 3

EQUIPMENT OVERVIEW

Accepted Answer

The PolyClean Mobile Drying System has six stainless steel hoppers. Each is capable of holding pellets weighing as much as 1000 pounds. Individual hoppers have heaters that range from 150-350 degrees Fahrenheit. They are broken down into groups of three. Each group then connects to a desiccant drying system that uses four beds. That system operates at 750 cubic feet per minute and is computer-controlled. At the end of the process, there is one last “finishing” hopper with a 350 CFM, two-bed system. It keeps material dry before packing out.
PolyClean’s equipment is top of the line. Feedback systems monitor parameters such as temperature and dew point. Touch screens allow the operator to control the process with ease. The drying system’s secondary tools (including an air compressor and central vacuum conveyor system) also set it apart.
All material being dried is conveyed into the hoppers using vacuum power. Drying occurs only after the hoppers reach a designated capacity. Then, hot and dry air forces itself through the pile. It rises from a basket in the bottom of the hopper through to the top. It carries out released moisture, drying the pellets. The hot air then doubles back through a desiccant bed. Here it dries thoroughly. Finally it is cycled back in a closed loop.Once a few hours pass, we test the material at the bottom of the hoppers. Assuming they meet the dryness standards established by the client, we begin the finishing cycle. Finishing is a computer-controlled process that pulls about 28 pounds of plastic from each of the hoppers and moves them into the finishing hopper. The finishing hopper stores the material in a stable environment and new pellets fill the others. The process within those hoppers continues as normal.Every few minutes, an additional collection of material moves into the finishing hopper. The length of time needed to complete a cycle varies according to the specific material and dryness requirements of the client. After a significant pile of pellets has accumulated, we pack out the material and move it into a new holding container. It can be a drum, a Gaylord box or a bag. If you’d prefer to keep your pellets in the action, then we can draw them from the drying system with an extruder and keep them perfectly inline.
