CONVERTER®

Technology & Process

CONVERTER® TECHNOLOGY ALLOW TO OBTAIN A FINAL PRODUCT REDUCED IN WEIGHT AND VOLUME TOTALLY DRY AND SAFE.

Converter® equipments are finalized to the treatment of waste of any provenience and composition to get simultaneously its sterilization or disinfection, physical modification, reduction of volume, dehydration and reduction of weight.

The process is patented and it covers all the models because all Converter® series are manufactured under the same working principle.

The Converter® patent peculiarity is that the waste is mechanically heated directly from its inside by means of the friction generated by material breaks, obtained by a powerful rotary blade made in Hardox, positioned on the cell bottom. All this is realized without using pressure or steam, yielding much more safe the entire treatment process.

Thanks to the pressure reduction in the treatment cell, the evaporation temperature becomes lower allowing to obtain a final product reduced in weight and volume, totally dry and safe in less than 30 minutes.
Fumes and condensate are extracted from the treatment cell and filtered.

All Converter® machines just need water and electricity to run. With the Water Recirculation system the water consumption can be reduced to a minimum.

THE PROCESS

STEP 1

WASTE LOADING

The waste is loaded into the sterilization chamber (by hand in small machines or by means of an on-board automatic loader) in its original packaging, in plastic or cardboard bags or boxes, and the lid is closed.

STEP 2

CRUSHING

The rotor starts and accelerate gradually while the material becomes finely grinded and the temperature rises quickly to about 100 °C.

STEP 3

EVAPORATION

The heat generated by friction in the material causes the evaporation of the waste moisture and the temperature remains firm at the value of about 100°C.

STEP 4

SUPERHEATING

Once all the moisture has been eliminated, the frictional heat causes the temperature of the material to rise up to 151°C.

STEP 5

STERILIZATION OR PASTORIZATION

The temperature of the material is held firm at 151°C during 3 minutes, under moist heat conditions, by mean of controlled water dosage.

STEP 6

COOLING DOWN

The waste is sprinkled with water in order to lower the temperature of the material to about 100°C. A vacuum pump then lowers the temperature further down to 60°C adiabatically.

STEP 7

UNLOADING

The treated material is unloaded by centrifugal force through the opening of a
servo-operated valve positioned at the bottom of the treatment chamber.
