Photo report: Open Day at Strauss Verpackungsmaschinen GmbH

The right machines for every stage of the value chain

During this year's Interaspa on 4 and 5 September at the Oelkers farm in Wenzendorf, Strauss Verpackungsmaschinen GmbH invited visitors to visit the premises. Sales Manager Matthias Kinzel led the attending trade visitors through the two production halls in Buxtehude and showed them an excerpt from the diversified machine catalog. FreshPlaza was there as well.

Strauss Verpackungsmaschinen GmbH was founded in 1945 and has a long tradition of mechanical engineering for the fruit and vegetable sector. Since the introduction of the first asparagus sorting machine in 1996, the traditional company has gradually specialized in the development of modern machinery for every stage of the asparagus industry - from harvesting to packaging. At the same time, plants for apples and leeks are being developed.

Currently the facilities are in two halls in the same location in
Buxtehude: There are 54 employees, including 14 trainees. In addition, new projects and machines are being developed on a permanent basis. For example, the company is working in close collaboration with the University of Bremen on a harvesting robot for green asparagus, with which harvesting is to be done completely without human intervention, except for changing the harvest boxes. The prototype is currently not in use, explains Mr. Kinzel.

A look at the OptiSort display, the external power indicator for
OptiSort asparagus sorting machines. The display can be used anywhere, displaying the performance data of the machine.

The SWL 17 weighing system with cutting unit (photo above) for asparagus. This scale is suitable for both white and green asparagus and continuously determines individual weights of the product portions. Thanks to a specially developed device in the scales, exact disposal can be carried out even at high speeds. As a result, the package weight is always within the preset tolerances. If a single weight can not be assigned to a product package, it is automatically returned to the beginning of the system and is put through another circulation.

The GUB Buncher is a bundling and labeling system for asparagus and other vegetables. The machine was launched on the market in 2007 and, as a stand-alone unit, clocks up to 25 units per minute and, as a double unit, up to 45 units. The GUB Buncher can be used either freestanding or in addition to the weighing and sorting systems.

Depending on the model, there are one to two special binding machines with gripper arms for attaching rubber bands on both sides. Optionally, a rubber band can be attached using the ElastTag process. Additional printers allow the ElastiTag tapes to be printed with specific product information.

Looking at the complete solution for weighing and packaging apples: First, the apples go through the combination weigher, which was developed for weighing and/or counting apples. The goods that do not fit the specified target weight of the bags, are led back to the start of the process. After the apples are packed the bags are closed with clips or tape, for example, or the bag is sealed.
