In the plastics industry, in order to limit production waste, plastic materials must be dehumidified up to a well determined residual moisture content.
The proper dehumidification of plastics before their transformation in the plasticizing screw is therefore a key factor for attaining quality processing.
MSM products range for plastic materials dehumidification includes:
Dehumidification systems can be used in different configurations, in order to implement single, centralized or multi-hopper solutions.
A wide range of process hoppers is available to satisfy any need.
Compressed air dehumidifiers of SD 4/28 YES-System series, can be used on all plastics transformation machines with throughput of up to 25 kg/h.
They can process plastic materials in granules or pellets (virgin and regrind).
SD 4/28 compressed air dehumidifiers main features are:
Single tower molecular sieve dehumidifiers are suitable for dehumidification of plastic materials in granules, pellets (virgin or regrind) for a throughput up to 50 kg/h.
Main features of single tower dehumidifiers are:
Single tower dehumidifiers, together with our process hoppers, can be installed directly on the trasforming machine or next to it, can include a suction valve and be mounted on specific mobile trolleys.
Options that can be integrated in the system:
Twin-tower molecular sieve dehumidifiers of DDT series, can be used in all plastic materials transforming machines, with a throughput up to 3000 kg/h, thanks to the wide range of models available.
They are suitable for plastic materials in granules, pellets (virgin or regrind), micro-granules and highly dusty flakes.
Main features of DDT series dehumidifiers are:
DDT models from 140 to 800 have the following exclusive features:

MSM, at the forefront in the field of drying and dehumidification, with its long experience, thanks to the modularity and wide range of its products, is able to study the best solution for the treatment of plastic materials, with focus on rationalizing the customer's production system and maximizing energy savings.
It's the traditional system, dedicated to the single material with dehimidifier/dryer serving one hopper only, in the ground configuration with trolley and suction valve, or to be installed directly on the transforming machine.
It's particularly useful in case of multiple material treatment (different materials and/or colours), with possibility of thermoregulation to be the same for all hoppers or differentiated by hopper (in case of DDT dehumidifiers, with the use of PR series preheaters).
Hopper can be mounted on specific trolleys or supporting structures, or installed directly on the transforming machine.
Both solutions above can be integrated in a central conveying system for maximum rationalization of raw material storage and treatment.
Dehumidification/drying can be located, for instance, directly in raw material storage area. Materials in treatment are eventually conveyed to the transforming machines through the central conveying system.
Insulated process hoppers, designed specifically for optimization of drying and dehumification treatments, have the following main features:
For integration, depending on the application, trolleys or support structures are available as an option.
