How to dry Plastics with Compressed Air Drying Procedure/Description

7

• Due to its physical property, air absorbs only a certain amount of moisture per cubic

meter. This always depends on the temperature. When compressing this air by means

of a compressor, accumulated water will be extracted

• By cooling down this compressed air subsequently to approx. 3 to 5°C with means of

a refrigerant dryer, a dew point of approx. -25 °C will be reached upon

depressurization of air (done within the compressed-air dryer)

• This air quality is sufficient for the drying of almost all plastics

• In order to dry plastics by means of depressurized air, it must be oil- and dust free. An

oil and dirt separator within the compressed air piping makes sure of that

ProTec – DryersDry air dryers, series D (carousel dryer)

Provides information about the absolute amount of water in the drying medium air

Impacts the drying velocity (concentration gradient dry air – material to be dryed)

Dew points below -30…-35°C make the energy input increase disproportional to the drying result!

ALAV = Automatic load adjustment method,

Indicated by return air temperature,

Value of an average of around 20 °C above the product inlet temperature

Option of all bigger dryers (series D and WT)

Option of all single and module drying hoppers

Energy saving due to ALAV function of dryer:

Regulation of total air fow rate via frequency control of the process blower

Lower power consumption of blower due to lower air flow rate

Lower power consumption of process heater due to lower air flow rate

Material protection/energy saving due to ALAV function of drying hopper:

Regulation of air flow rate via throttle valves at each hopper

Optimal drying result due to need-adjusted air flow rates

Lower power consumption of process heater due to lower air flow rate

SUPER SOMOS = Automatic adjustment of the dessicants regeneration quantity

to the actual need

Option of all dry air dryers

Rregeneration at regular intervals,

if a lot of water needs to be adsorbed

Power saving mode,

if less water needs to be adsorbed/if material is dry

Software calculates waiting time

which follows the regeneration time

Neither regeneration heater nor blower

operate during waiting time

IDMS (Integrated Drying Management System) stands

for adjustment of dwelling time within hopper to the

drying material‘s throughput.

Independent from IDMS-usage, the drying hopper is

always being operated completely filled, dry-air

generator conditions regarding air volume and loss of

pressure therefore are steady.

Advantages:

The effective dwelling time is adjusted to the actual

throughput.

No additional height required (as with tapered

diameters hopper).

No thermic damage/overdrying of material.

Alternatives:

Movable level indicators

Hoppers with tapered diameters

Hopper weighing

IDMS: Perfect for usage at times of considerable

production-related fluctuations of material throughput or

at demand of materials being dried at considerable

different dwelling times within one hopper.

Temperature profile within drying hopper with and without

IDMS

Left: Temperature profile within drying hopper with ALAV-System

(T1 = measuring point of return-air temperature)

Right: Only the material below measuring point T4 is being warmed

up to drying temperature. The rest remains at surrounding

temperature. Therefore no thermic material damage at longer

dwell time within hopper.
