for terry fabric CA-77S
dryer CA-77S has been designed as a result of ALEA's long experience
in terry fabric finishing. The main features which differetiate
this machine from others are:
air cushion which guides and supports the cloth, causing a vibration
so that the pile raises to give a soft handle and a perfect drying
effect on both sides
evaporation rate due to the special nozzle design and to the high
speed of the air, passing through the cloth
down of the fabric and automatic removal of the creases. No stretchers
centering of the fabrics, which can be fed in parallel, without
danger of overlapping
to heat the dryer by gas, steam, thermal fluid, or high pressure
air cleaning filters, with speed adjustable according to the different
qualities of terry fabric. The use of automatic filters is essential
for terry fabric drying as this fabric produces large quantities
of lint, which would quickly block up normal filters and lower
the drying efficiency of the machine. Hence the automatic filter,
being continously cleaned, promotes maximum drying efficiency
moving mechanical parts inside the drying chamber: minimum maintenance
current drive in order to ensure perfect synchronisation and a
minimal noise level.

It is possible to see that the fabric is already perfectly flat.

section of 2 compartments CA-77S. The recirculation fans are located
on the front wall of each compartment, allowing the connection of
the compartments two by two. This design allows an excellent accessibility
for cleaning an maintenance operations.
On the suction side of the fan, the recirculating air is drawn through
an automatic filter unit. This comprises a flat stainless steel
mesh with a suction arm rotating on the surface of the filter continually.
The speed of this arm is adjustable.
The air is then passed over the heat exchangers or via the heating
ducts in the case of direct gas heating and through special nozzles
onto the terry fabric. The upper and the lower nozzles have an offset
alignment, so that the air impinges on the fabric from different
angles, allowing the pile to draw up perfectly.

of the CA-77S, showing the cloth passage.
- Single compartment complete with cloth feeding and plaiter.
- Two compartments in line.
- Four compartments in line, with dancing roll between the first
and the second group of two compartments.
- Six compartments, partially superposed and elevated.
- Eight compartments superposed.
