Dry cleaning machine DRD
from MAS

Effective drying
& cleaning of plastics

Raw mate­ri­als and plas­tics need to be cleaned thor­ough­ly and exten­sive­ly before they are fed into the extrud­er. The DRD plas­tics dry­ing machine from MAS removes mate­ri­als such as sand, soil and dust, water, and oth­er coarse impu­ri­ties from pre-shred­ded plas­tic frac­tions. The MAS plas­tics dry clean­er cleans and dries in a sin­gle process, and is also extreme­ly user-friend­ly and low-main­te­nance.

A sig­nif­i­cant advan­tage: no water or treat­ment is required: the wash­ing-with­out-water prin­ci­ple! Dis­cov­er the many ben­e­fits of our DRD plas­tics dry­ing machine before con­sid­er­ing a wet wash­ing sys­tem!

Convincing
advantages

no
water consumption

effec­tive dry and clean­ing with­out water or water treat­ment, and thus low­er oper­at­ing costs

Low investment:

max­i­mum effec­tive­ness at low expense and with low space require­ments, and thus quick amor­ti­za­tion

Simple
installation

ful­ly auto­mat­ic con­trol and sim­ple imple­men­ta­tion into exist­ing process­es; a defined mois­ture lev­el can be set via a batch process

Longer service life:

cleaned input mate­r­i­al reduces wear and main­te­nance require­ments for down­stream equip­ment

How the plastics drying machine
works

The plas­tic is sucked through the spe­cial­ly designed rotor into a cylin­dri­cal cham­ber and rotat­ed there. The plas­tic is sucked through the spe­cial­ly designed rotor into a cylin­dri­cal cham­ber and rotat­ed there. The frac­tion to be cleaned is sur­round­ed by warm air, dried with tur­bu­lent air cur­rents, and cleaned. Impu­ri­ties such as sand, soil or fine par­ti­cles are sep­a­rat­ed using sep­a­ra­tion sieves. Heavy par­ti­cles (eg. small stones, wires or met­al parts) are removed via a heavy mate­r­i­al sep­a­ra­tor. In the sub­se­quent sec­ond clean­ing stage, any fine dust par­ti­cles that are still present are removed. The sec­ond clean­ing stage can be omit­ted for damp mate­ri­als with a low degree of con­t­a­m­i­na­tion. The sys­tem is ful­ly auto­mat­ic. Both clean­ing stages run in par­al­lel and are per­fect­ly coor­di­nat­ed. The sec­ond clean­ing stage can be omit­ted for moist mate­ri­als with a low degree of soil­ing. Sys­tem con­trol is ful­ly auto­mat­ed.

Depend­ing on the degree or type of con­t­a­m­i­na­tion, the DRD sys­tem is used as a stand-alone vari­ant or to opti­mize (wet) wash­ing sys­tems as a pre- or post-clean­ing stage.

Single-stage or two-stage?

Dry clean­ing of plas­tic can be done in sev­er­al ways using the DRD prin­ci­ple. The two-stage process dries and cleans at the same time, for exam­ple con­t­a­m­i­nat­ed and moist films. The mate­r­i­al is dried by draw­ing in air from above while heat­ing it. In the dou­ble stage, anoth­er clean­ing cham­ber with­out heat­ing ele­ments can be switched on for just clean­ing. The result: opti­mal clean­ing and dry­ing.

Alter­na­tive­ly, the dry clean­er can also be used with a focus on the actu­al dry­ing and clean­ing at the same time. Mate­r­i­al with resid­ual mois­ture con­tent from the wash­ing sys­tem is dried here and at the same time any wash­ing residue (fines) is removed. The MAS experts will def­i­nite­ly find the opti­mal solu­tion for your area of appli­ca­tion.

What is MAS?

Found­ed by recy­cling pio­neer Hel­muth Schulz in 2006, the com­pa­ny is rev­o­lu­tion­iz­ing the exceed­ing­ly high qual­i­ty stan­dards of twin-screw extrud­ers for the recy­cling indus­try. MAS mas­ters the chal­lenges of mod­ern recy­cling and upcy­cling require­ments thanks to its patent­ed tech­nol­o­gy and became an inter­na­tion­al dri­ver of inno­va­tion in no time. Cus­tomers around the world ben­e­fit from envi­ron­men­tal­ly friend­ly added val­ue while sav­ing ener­gy and resources.
