Recycling and regeneration are playing an increasingly important role in the world of plastics driven by new circular economy models.
The biggest problems with recycling plastic are the bad smell in the final product and VOC humidity and dust in the process. Odor is relevant in recycled olefinic resins such as rPE, rPP and rHDPE.
The resin contamination in packaging applications takes place through different diffusivity phenomena such as migration, adsorption, and absorption.
ACERETECH’s recycling line integrates Piovan Easypure Deodorizing technology, it is the solution to strip away volatile substances and contaminants in recycled plastic exploiting a hot air flow that heats the material inside the hopper and it is also the carrier to strip away the smelly substances
Modular design supports throughput of 500kg/h, 700kg/h, 1000kg/h, 2000kg/h and more.
EASYPURE Deodorizing Process
EASYPURE exploits the effect of temperature on the kinetics of molecules by increasing their diffusion within the granule and their ability to be released into the air.
Releasing and stripping phase occur at the same time driven by hot air flow that provides heat and is also the carrier to strip away the VOC.
The deodorizing process has been successfully monitored and verified through third-party laboratories.
System Highlights – ACERETECH recycling line with PIOVAN deodorizing technology -Optimal Performance and Cost-Effectiveness.
EASYPURE – ODOR MINDER
ODOR MINDER is a compact instrument installed directly on hopper and is composed by:
* Auto-sampler pump with the automatic cleaning process
* Dedicated motherboard with 2 ethernet port for communication with PLC and HMI
* Sensors board characterized by:
- High sensitivity and selectivity
- Time stability sensors
- High reactivity to gas presence
It is a unique and innovative solution that finally gives qualitative information on the odor status of material, driving operators in optimizing the deodorizing process saving time and energy.

EASYPURE – ESP UNIT
ESP UNIT provides the air flow according to throughput and deodorizing level of the final product, heating power is provided by resistance equipped inside the ESP unit or monted on the hopper, the control system is embedded in the cabinet
EASYPURE – EPH HOPPER
EPHHOPPER is designed to maximize the stripping effect through hot air flow and provide homogeneous heat to allow the release of odorigenic substances without overheating, can be equipped with level sensors or load cells.
EASYPURE – CONTROL SYSTEM


EASYPURE – CONTROL SYSTEM
CONTOL SYSTEM is based on PLC with a 7” touch screen, managing:
* Blower with inverter in ESP unit for airflow control
* Load cells in EPH Hoppe
* Overall material loading control
* Monitoring hopper temperature profile
* Monitoring of the deodorizing process through Odor minder
