Vacuum conveyor with lifting and swiveling columns |
In many industries it is still common practice to fill filling systems, presses or containers by hand from above.
This process is usually unergonomic for employees and rather time-consuming. This procedure often harbors undreamt-of dangers, for example that of a dust explosion.

An alternative to automated filling are lifting and swiveling columns that are equipped with a vacuum conveyor for material transfer. The vacuum conveyor sits in a holding fork that is mounted on the lifting column and can be steplessly raised and lowered.

Bread crumbs are often used in the production of fish fingers and other fish dishes. The task was to empty the big bags filled with breadcrumbs and then to feed the breadcrumbs to the machines for further processing.
A cost-effective solution was sought in order to empty the big bags and continue to use the existing crane. The customer then preferred to use mini hoppers as emptying aids. These have a small overall height, are easy to handle and cleaning when changing products is easy. Big bag emptying and conveyance of breadcrumbs
The big bags are emptied and transported to the machines by four VS 250 vacuum conveyors. 12 tons of breadcrumbs are conveyed and processed every day.

The coffee roastery client Martermühle: rates itself highly. “Fragrant, first-class, fresh coffee – this is our promise to you. We only purchase the best beans from suppliers we trust and from plantations we know.”
The coffee roastery Martermühle also has the same quality claim when new equipment should be planned and procured for the improvement of the work processes. A modern filling scale should be completed on a new transport and supply system for coffee beans. The amount of coffee beans processed daily totaled 500 kg – the restriction on best quality and small lots should guarantee a fresh coffee aroma.
Originally, coffee beans were poured in small amounts by hand from barrels into the collection hopper. The then placed filling unit fills doses of coffee in different retail containers and sealed and marked them. The process was improved to be more work ergonomic, cleaner and simpler but without taking away from the unique aroma of the coffee.
After test runs, it was decidedto use the Volkmann VS 200 LT vacuum conveyor. The slow transport provided by the exceptionally compact and quick and easy to clean Volkmann conveyor system proved less stressful to the comparatively sensitive coffee beans, and this was critical.
The extraction of material by the suction lance directly from the barrel now makes loading the filling scale operator friendly, quick and safe. The conveyor system can be easily taken apart and cleaned with minimal intervention and without tools for pending grade changes.
What our clients are saying today about the selected solution:
“For our employees, the work situation has been considerably simplified, and the design makes it possible to clean it quickly.“

The Production of care and hygiene products requires the transport and dosage of highly flammable resin granules in a mixer. Minimum ignition energy of the substance to be transported is 3 mJ (MIE 3 mJ).
In the previous procedure, drums were filled with resin and heated up in ovens; then the liquified resin was mixed with another liquid in a stirred vessel. This time-consuming and comparatively cumbersome to master process led to production bottlenecks.
The customer turned to us with its request for a safe, yet, at the same time, flexible work environment. In close consultation between the provider and the user, they agreed to design a flowing and space-saving process.
Big Bag Station
After the process conversion, the resin granulates will no longer be prepared in drums but rather in bulk bags. The material to be transported is now placed centrally and in the easily reachable material storage above two bulk bag unloading stations. Whereby the bulk bags are alternatingly unloaded and standstill times for container changes are avoided.
Two Volkmann Conweigh vacuum conveyors suck the material from here and transport it over 60 or 85 m distance and 12 m high to the stirred vessel with a conveyor capacity of 2 tons per hour.
The Conweigh systems ultimately supply 100 precisely measured grams of the transported material to the stirred vessel where it is heated and mixed with other liquids.
Conweigh-System
Now various flammable materials from the client can be safely transported with the selected system. Studies have shown that the suction lines can be almost completely emptied so that additional cleaning measures are not necessary in the case of pending material changes which contributes to the desired high flexibility in the system. The entire system is designed and made in conformity with ATEX.
The client chose the VOLKMANN solution for the new design of the process not least because of the close cooperation and competence specifically found in explosion risk prevention. The proposed solution also appeared attractive on account of the hygienic aspects and the operation and maintenance friendliness.Volkmann considers the user’s needs with knowledge and experience and therefore develops optimal results and processes.

Drum emptying – remove bulk goods and powder from drums |
In some situations the pick-up of bulk product is from drums or barrels and depending on the product this can be easy or more difficult to do. Products flow easily or be strongly adhesive. We have developed various solutions to empty drums almost completely and without a lot of operator intervention.
The barrel is mounted in a holding station and is tipped by hand. To suck the product out of the barrel a suction lance is inserted from above. The drum emptying device is adapted to the product and the task situation. Drum emptying where a liner is present is then also possible.
As the product is sucked out of the drum by vacuum conveying, the suction lance sinks down into the drum under gravity and thus gradually empties the contents. The process is supported with a vibrator, which is attached to the station below the platform, in order to help extract difficult-to-flow products.
For products that tend to be very dusty or should be contained as much as possible, it is possible to mount a corresponding lid on the barrel. This is equipped with a ventilation filter and a sealing sleeve and thus prevents dust from escaping.
