Transportation & Storage

The octabins with various frozen vegetables are delivered by forklift truck and placed in one of the tippers. The tippers empty the octabins into their corresponding hoppers. These hoppers have a detection system that indicates which hoppers need to be refilled.

From the hoppers, the vegetables are weighed according to a specific recipe and poured into an underlying redler. The sum of these weights forms exactly the contents of 1 octabine. Once everything has been weighed, the vegetables are transported to a screw bunker.

This serves as a buffer. This way, the next batch of vegetables can already be weighed. The screw conveyor only feeds the mixing drum when it is free.

Mixing & Packaging

A new mixing drum was developed for this process line. This has the capacity of 1 octabin and is driven by 1 gear. During filling, the drum turns in one direction; during emptying, it turns in the other. The specific shape of the blades ensures that a good mixture is obtained and that the product only leaves the drum when it is turning in the right direction. Once the product has been sufficiently mixed, it is deposited in an underlying octabin. This is supplied by a number of roller conveyors.

Integration & Automation

Layout made with existing equipment, supplemented with our machines. The limited space, accessibility and short realisation time were the main challenges. We also designed and installed platforms and staircases. This is to guarantee safe and smooth cleaning. Special attention was also paid to the accessibility of the octabins under the mixing installation. Here, the operators must prepare and close the octabins in an ergonomic way.
