Squeeze Dryer

That is an industrial Plastic Film Squeezer Dryer. This heavy-duty machine is a critical part of a plastic recycling line, designed to transform wet, bulky plastic waste into a more manageable, dry form.

Essentially, it’s like a giant, high-powered industrial wringer.

How It Works

The machine uses a mechanical screw-press principle to process materials like PE/PP films, woven bags, or flakes after they have been washed.

1. Feeding: Wet plastic is fed into the stainless steel hopper at the top.

2. Squeezing: A large internal screw rotates, pushing the material through a narrowing barrel. This creates immense physical pressure.

3. Dehydration: The pressure forces water out through a specialized screen. Unlike thermal dryers that use heat, this relies on kinetic energy and friction, which is often more energy-efficient.

4. Pelletizing/Compacting: As the material is compressed and slightly heated by friction, it is forced through a die-head at the end, often resulting in semi-molten “popcorn-like” lumps or dense flakes.

   Key Features

   • Control Cabinet: The separate tall gray box on the left houses the electrical components and PLC (Programmable Logic Controller) to manage motor speed and torque.

   • High Efficiency: It can reduce moisture content from roughly 40-50% down to 3-5% in a single pass.

   • Labor Saving: It replaces traditional centrifugal dryers and hot-air drying pipe systems, which take up significantly more floor space.

   Common Applications

   • LDPE/LLDPE Film Recycling: (e.g., stretch wrap, grocery bags)

   • PP Woven Bags: (e.g., cement or flour sacks)

   • Agricultural Films: (Greenhouse plastics)
