Turn-key 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.

Technology & Feature

PET Recycling Extrusion Equipment
Manufactures the dominant PET Plastic Recycling and Extrusion Equipment in the industry. We fully understand and apply all the necessary processes for successful plastic recycling. Moisture removal, material compaction, and prevention of hydrolytic decomposition stabilize and increase intrinsic viscosity ( IV ) values of PET materials. The result - high efficiency manufacturing. The following describes some key features of our technology.

High Stability IV Values 1.Twin Hot Air Pre-Dryers : Continuous batch pre-drying. Numerous small batches increase efficiency, timer controlled.
