After dewatering, the moisture rate of PET flakes will be decreased to 2-3%; if the heat exchanger is supplemented subsequently, the moisture rate can be further reduced to 0.7 percent. It’s more than enough to suit the needs of downstream applications. To achieve the largest output capacity and lowest moisture content, specially designed shaft and anti-block screens are advantageous. The plastic dryer has the advantage of having a low breakdown rate and being easier to maintain. The next generation of PET flakes dryers features a step-type shaft design that separates water while also cleaning PET flakes.
