The GEA Albro Theta is the flagship of the Albro range. Theta is a vacuum filler suitable for handling freeflowing and non-free flowing products within a wide range of industries. Its state of the art design represents 70 years of powder filling development. This machine is available in four frame sizes with up to 40 filling heads.
Output speeds can be over 400 containers per minute and it will handle container sizes up to 3kg.
Filling Mechanism:
At each filling head a straight vertical tube leads from the hopper directly through the filling nozzle into the containers to be filled. The filling nozzle also incorporates a vacuum tube and a vacuum breaker tube. Although there is no valve, powder is retained in the nozzle until a vacuum is induced when a container is in the filling position. The container then forms an integral part of the totally enclosed vacuum filling circuit. There are no moving parts in contact with the product.
GEA Albro machines feature sanitary designs and components that can be quickly removed and replaced.
The filling cycle commences immediately after the container is lifted against the filling nozzle; the air is drawn out and the product flows into the container from the hopper above. When the powder reaches the desired level in the container, it stops flowing and air or inert gas is let in to release the vacuum. Filling will not take place until a container is in position, or if the container is badly damaged, as the vacuum circuit is not complete.
Features include:
- Volumetric Fill, standard technique for high accuracy filling of a wide range of products
- No Moving Parts, for minimal product breakdown and no product contamination
- Self Emptying Hopper, prevents ‘dead zones’ - minimises cleaning and reduces change over time
- Tool Free Change Over, for minimum ‘downtime’, maximum ‘uptime’
- Powder Spray Nozzles, to spread filled powder and prevent scoops rising in the container during filling
Optional features include:
- Timed Fill Machines, eliminates high variation of fill for ‘liquid’ powders e.g. Talcum Powder.
- Pulse Control Fill, for fatty chocolate/cocoa products
- Individual Head Update, minimises variations in filling head performance,
maximising filling accuracy
- Vibration Facility, provides compaction capability for agglomerated products
- Top-Up System, to minimise ‘give away’ for minimum/ nett weight containers
- Soft Reject, gentle controlled rejection of ‘out of weight’ containers
- Gassing System, to maintain the reduced residual oxygen content in the final
product.
