Solutions for the optimization of production processes

Our systems offer a high level of operating safety and can be integrated into almost every existing process.
The modular form of construction enables this technology to be combined simply with existing transport solutions.

Product intake

The material to be transported can be fed into the conveyor system from various containers. We therefore provide two different processes for feeding the material into the conveyor system. A conveyor pipe removes the material to be transported from above, e.g. from sacks, barrels, tanks or cartons. This is a manual type of product extraction.

We recommend using a feed adapter to enable an automatic product intake. This can be mounted under various existing systems.

It may be a silo, a big-bag station or even a feed station into which the material is poured.

Product intake
Feed adapter

Feed adapter
The inlet funnel of the feed adapter is directly connected to the silo or a feed station via a flange or a clamping ring. The material flows through this inlet into the underlying horizontal intake pipe, where it gathers as a plug.


Conveyor pipe:
The conveyor gun, which sucks in the material from above, may also consist of an outer and inner pipe. In contrast to a feed adapter, with its horizontal injector, in this case the material/air mixture is supplied to the conveyor line through the inner pipe.

Product discharge / transition pieces

In completely closed systems, the outlet module can, for instance, be connected directly to a processing or bottling plant. Support collars and weld ends are used for this purpose. In particular, screw-mounted support collars can also absorb the weight of the conveyor, so the need for additional wall-mounting or frames is either partially or entirely removed.

Transition pieces from the vacuum conveyor to the product recip- ient can be tailored to the customer’s requirements.

Big Bag Stations

This practical Big Bag Station for vacuum conveying is one of our latest products. It offers several advantages compared to a smaller silo. The filling funnel, pipe connections, filters and taps are already pre-installed. This means that it can be easily connected directly with the pipeline of a vacuum conveying system. In addition, LUTENA-Bag- Star is highly versatile in terms of its usage, is easy to transport and is also very cost-effective.

Transport lines

Pipelines or vacuum-tight hoses with embedded steel spirals are used to transport the material between the product intake and the vacuum conveyor. Combinations are also possible. In general, for longer lines, conveyor systems with stainless steel pipelines are more efficient and faster, as they generate less frictional resistance. They are the best choice for stationary systems.

Transparent conveying hoses are generally used for distances up to 20m. They have the benefit of simpler and faster assembly and also give the operator the opportunity to see what is happening in the transport line. Potential blockages are easier to localise.

Control unit

All of our vacuum conveyors can be delivered with and without a control unit. Conveyors without a control unit can easily be retrofitted.
