Hygiene
- Achieves the highest hygiene level thanks to fully stainless steel
execution with self-draining surfaces.
Maintenance / Cleaning
- Perfect accessibility to the machine from both sides for die change-
over, cleaning and maintenance
- Low running costs due to high quality components and easy access to all
machine modules. The lifting station is maintenance free, only few
lubrication points inside the machine.
Flexibility
- Easy dismounting of conveyors belts for cleaning, quick replacement of
knives (within 10 minutes at dismounted format)
- Die top and bottom part removal with precise mechanical docking system.
Enables the die changeover within less than 10 minutes thanks to the solid
die-set trolley. Easy and quick dismounting / mounting of the tray
carriers.
- Individual temperature control of sealing heads (with max. 6 circuits)
for high reliability and fast heat-up.
- The TwinStar9 can be executed in a one-lane ore double-lane version.
Capacity / Efficiency
- High speed and efficiency thanks to state-of-the-art machine- and drive
technology, mostly servo drives.
- High production output based on a large sealing area (930 x 380 x 110 mm)
- Vacuum pump: possibility for located inside the machine up to 300 cbm/h.
Safety
- Safety is assured thanks to 850 mm free space between tray carriers and
in-feed/out-feed doors.
- Certified system in case of an application with high level of oxygen
allows the utilization of a standard vacuum pump.
- Protruding object detection (POD) supports avoidance of tray crash and
machine / format damage, caused by protruding products in the tray (Option)
Complete Die-set for MAP application - sealing with modified atmosphere.
Two-lanes die configuration. Tray running direction either wide edge
leading or narrow edge leading (depending application, capacity and tray
size) Basic die-set concept designed to run tray depths from min. 15 mm
up to max. 110 mm
The Die-set consists of the following parts:
Topside die-part including sealing heads and knives (either inside cut
or outside cut is possible, depending application and materials)
Bottom side die-part including sealing frame and support plates
2 Tray transport arms, for moving trays into sealing area and
discharging sealed packs. The technical design of the tray transport arms
allows the working with different heights of Trays without modification.
