PET Bottle Washing Line


KOWIn dedicates to research and develop various types of washing machine of the turn-key plant.
Plan required machines as per customer's recycle material. Supply module, full line package and also customized planning.
Different from the general washing machines in the market, KOWIn washing machine enhances
the application rate of recycled material by completely washing and removing the dirt, such as oil, sand and others from the material.

Advantages :

Water-saving, power-saving, low manpower, human-based operation. Cleanness of washed plastic material by KOWIn washing machine is 20% ~ 30% more than the ones by general washing machine.
Without detergent, it still gets high cleanness and completely separates different plastic materials and contaminants by specific gravity. Moisture content of material after washing machine & de-watering machine will be less than 3%.

Technology & Feature

  1. Patented washing machine. Save much water during washing, get the highest cleanness and reduce the times of screen changing during extrusion-pelletizing.
  2. Patented squeezing-drying machine. For after-wash film and bag material. Moisture content after squeezing-drying machine will be less than 3 %. Reduce the unstableness during extrusion-pelletizing and increase the compactness of the pellets.
  3. Patented centrifuge with openable design. For after-wash flakes of rigid material. Moisture content after centrifuge will be less than 3 %. Increase the compactness of the pellets during extrusion-pelletizing.
  4. Special design of sinking & floating separation tank. Completely separate different plastic materials by specific gravity. Non-disturb design; achieve fast and stable separation.

Design and structure

  • PET Washing Line Design
    Bale breaker
    For baled recycle plastic material like PET bottles and others. It separates the plastic material rapidly. For stable feeding and convenient in manual inspection. Increase production efficiency.
  • PET Washing Line Struction
    Label removing machine
    Largely remove the labels from bottle materials in advance; label removing rate approx. 80 % - 90 %. With label suction machine after washing and manual inspection, it removes the remaining labels. Increase the production quality of pelletizing.
  • PET Washing Line
    Cutting machine
    Cut whole roll or oversized recycle plastic materials. After cutting then it goes to crushing for stable feeding. Manpower-saving and increase production efficiency.
  • PET Washing Line Design
    Roughly filtering rotary trommel
    Separate the sand, soil, metal and other contaminants from the plastic recycle materials. Increase production efficiency. Reduce machine wearing. Manpower-saving.
  • PET Bottle Washing Line
    Manual inspection belt conveyor
    For all types of recycle plastic materials that needs color separation or metal and contaminant inspection. For example, it increases the cleanness for PET bottle recycling.
  • PET Bottle Washing Line Struction
    Shredder
    Special type blade design. Blade is 3 times longer than general shredder. Shredding capacity is 2 times more than general shredder. Low horse power. Low noise.
  • Washing Line Struction
    Crusher
    Patented rotary blades & fixed blades design. With a special rotating angle, the blades function as scissor and claw knife. Heavy-duty construction-noise level be minimized. Power-saving.
  • Plastic Washing Line
    4 in 1 Washing tank
    It is especially designed for crushed plastic flakes, with oil, mud, sand, soil, or dirt on its surface. With really washing performance. Available for adding hot water and detergent ; detergent recyclable.
  • Plastic Washing Line Design
    2 in 1 Washing tank
    It can wash film and general plastics. Hot water washing and detergent washing in one machine design. The only design in the world that can wash film.
  • Plastic Washing Line Struction
    Single tank type washing machine
    It is especially designed for crushed plastic flakes, with oil, mud, sand, soil, or dirt on its surface. With really washing performance. Available for adding hot water and detergent ; detergent recyclable.
  • Washing Line
    Floating and sinking separation tank
    Patented design. It can separate floating and sinking materials with similar specific gravity, such as Styrofoam and PE.
  • Washing Line Design
    Centrifuge
    Patented liftgate type design. Easy to clean.
    High de-watering rate. Moisture of non-foam plastic material after centrifuge to be less than 3 % and can be sent to extrusion-pelletizing directly.
  • PET Washing Line
    Squeezing-drying machine
    Invention patented design. Especially for film & bag material, moisture after squeezing to be less than 3 % and can be sent to extrusion-pelletizing directly.
  • PET Bottle Washing Line
    Extrusion – pelletizing machine
    High capacity and easy-operation, it allows customers to produce high quality recycled pellets. Heavy duty construction design, no vibrating in machine while production. Low temperature palletizing. Very low ampere when in full production. Energy-saving.
  • PP / PE Turn-key washing line : Available for floating material, such as PP, PE or other floating materials.
  • PET / PC Turn-key washing line : Available for floating material, such as PET, PC or other sinking materials.
  • Not only for industrial waste, but also for Post-consumer waste. Especially for fluffy material.
