6. Functional description
»
This functional description is addressed to the operators of the equipment.
This functional description assumes general familiarity with drying equipment.
64.10-0271GB01 11/03
It should be verified that the operators do indeed have the appropriate skills.
Functional description 6-1
Dry Flex M
6.1. General Information
The dryers work according to the dehumidified air principle, i.e., the air is not only heated but also
dehumidified before it flows through the drying hopper.
In this manner, plastic granules can be dried down to a very small residual moisture content.
The drying takes place continuously, i.e., there are no rest periods due to regeneration of the drying agent.
F
The dryer is rated for continuous operation.
All function sequences are fully automatic.
The dryer is equipped with two drying cells. One drying cell is part of the drying cycle; the other
drying cell is regenerated simultaneously.
If a malfunction occurs in the drying cycle during the program run, regeneration is not interrupted,
but continues until the program end has been reached. This guarantees that one regenerated
drying cell is always available.
The air inside the switch cabinet is cooled by a cooling appliance for the protection of temperature-sensitive components (if present, optional).
With the digital timer (optional) the dryer can be switched on and off at set times.
Dew point dependent regeneration switch (optional)
64.10-0271GB01 11/03
The dew point temperature is monitored continuously. The valve system switches to the freshly
regenerated drying cells only after the selected dew point temperature has been reached. The humid drying cells are then regenerated. After the cooling time the drying cells are ready for operation again. The valve system switches to the freshly regenerated drying cells only after the moisture content of the drying cells which are in the drying cycle have reached the setpoint value.
Functional description 6-2
Dry Flex M
6.2. Drying Hopper (Optional)
The material is dried in the drying hopper.
The dehumidified air is conducted through
the material in the drying hopper and takes
up moisture. Drying hoppers must have the
appropriate dimensions for their specific use
so that the desired final moisture content is
reached. When refilling a drying hopper, the
material must first be dried completely before
material can be taken out for the first time.
If material is taken out continuously, there
must also be a continual addition of material
into the drying hopper (continuous drying
process). New (moist) material is conducted
into the upper opening of the drying hopper
and slowly reaches the material outlet at the
lower end. On its way from the upper to the
lower end, the material is dried down to the final moisture content.
In order to guarantee a continuous drying
process, we recommend that you always
keep the drying hopper filled completely.
Drying hopper
6.2.1. Hopper heaters (optional)
64.10-0271GB01 11/03
If differing drying temperatures are required in the different drying hoppers, hopper heaters must
be installed on the drying hoppers. The drying temperature of each drying hopper can be set centrally at the dryer.
Functional description 6-3
Dry Flex M
6.3. Connection to a Pneumatic Conveying System (Optional)
Your drying facility works best in combination
with a pneumatic conveying system. In this
way, your drying hopper will always be supplied with sufficient material.
The facility will only take as much material as
is required by the processing machines. Therefore, the drying result will always be the
same.
Colortronic drying hoppers are equipped
with a suitable flange for adding a Colortronic
pneumatic conveyor.
Suction boxes with one or three suction tubes can be supplied as well (optional). These
suction boxes are developped specifically for
this type of hopper.
A
The loading of the conveying line with material is adjusted by closing or by opening of the
control cover (A).
Suction box
6.4. Return Air Cooler (Optional)
F
A return air cooler must be employed if the return air temperature is higher than +65 °C (149 °F).
64.10-0271GB01 11/03
A return air cooler improves the efficiency of the drying cells.
&
The lower the return air temperature, the better the efficiency of the drying cells.
The return air cooler can be connected to a coolant circuit or to the water mains network.

The place selected for installation should be as free of vibrations as possible.
The main switch must be freely accessible.
Ground the equipment against electrostatic charging.
F
The machine must not be tilted or laid on its side.
Because of its compact construction the dryer can be installed directly beside the processing machine (drying hopper on the processing machine) or with one or more drying hoppers as a movable facility (compact facility).
Special foundations are not necessary for installation.
The dryer must be installed on a level surface and must not be exposed to excessive humidity.
The maximum permissible ambient temperature is +45 °C (113 °F).
To facilitate servicing, the dryer should be installed in such a way that that it is accessible from
3 sides. Make sure that the air filters can be changed without problems.
To conserve energy, keep the distance between dryer, hopper and processing machine as small
as possible.
The wheels of the compact unit should be locked to ensure stable installation.
The foil should be removed from the drying hopper.
7.3. Storage
64.10-0271GB01 11/03
The control system may only be stored at temperatures from 0 to +55°C (32 to +131 °F).

8.1. Installation of the exhauster fan for regeneration of exhaust air
When plastics are being dried that release harmful gases during the drying process, care must be
taken that the regeneration exhaust air is disposed of in an environmentally sound way. At the
same time the throughput of the regeneration blower must not be altered. It should be noted when
assembling a disposal system (e.g. an exhauster system) that the regeneration exhaust air is very
humid. Thus condensation may form, which must not under any circumstances return to the dryer.
8.2. Connection of Return Air Cooler (Optional)
F
A return air cooler must be employed if the return air temperature is higher than +65 °C (149 °F).
The return air cooler can be connected to a coolant circuit or the water mains network.
Observe the water flow with connection to water mains network. The coolant circuit must be dimensioned acccordingly.
Remove the side panel of the dryer.
