In this project, the customer requested an automated mobile unitplant that could loosen frozen vegetables from bulk storage in preparation for further conditioning. The plant not only had to be suitable for an environment of -20°C, but also had to be portable for cleaning and maintenance.

Product reception is done from bins placed on a hydraulic tipper with position detection. The tipper feeds the product into a robust hopper covered by a sturdy grid. This grid ensures that very large clusters cannot damage the system.

The hopper feeds the automated crusher, in which two shafts equiped by pins loosen a full box of frozen product. A secure inspection door allows easy access to the crusher for inspection and maintenance.

After the process in the crusher, an extraction shaker with breaker roll ensures an even feeding to the built-in extraction screw. The breaker roll reduces any remaining small lumps and is easily manually adjustable in height via a hand wheel. The extraction screw is equipped with a double hopper to ensure continuous filling, even when replacing a full box.

The entire installation including main control cabinet, stairs and operator platform is built on a mobile frame that can be easily moved with a forklift for maintenance or cleaning outside the freezing zone.

Our colleagues from Bruynooghe Automation took care of the automation of this project. They equipped the installation with programming, control cabinets and buttons and the necessary safety components.
