Grinding has the same function as chewing. It occurs at the beginning of food intake and makes the food digestible and edible by breaking it up. There are particularly high demands on the feed in fish and shrimp feed production. The aquafeed should provide optimal nutrients and also be healthy and easy to digest without losing its texture in the water. The residues must be environmentally-friendly at the same time so that water bodies and nature can be protected. This basic principle holds true, even though complete uptake by the respective species is the objective.
Our grinding solutions guarantee the optimum fineness of your raw material to ensure economical extrusion of the feed and consequently provide a high level of end product quality. Economic feasibility for us means that your grinding will also deliver the desired crushing result for years to come. We work with our customers in aquafeed production to utilise the available raw materials for high-quality products and efficient processes.
The right fineness, a guaranteed grain size and reliably cleaned grist at the extrusion interface primarily avoid costly extruder downtimes. Yet they also ensure energy-efficient drying and cooling as well as optimum oil absorption of the finished pellets in the coating process. This in turn has a positive influence on the packaging process and the shelf life of the finished product thanks to the high pellet stability. That’s why we say at Tietjen: It all depends on the grinding.
Our TICM impact classifier mill, which we have been using together with our partners in the production of aquafeed since 2018, allows us to fulfil the above-mentioned requirements for fine grinding. The TICM combines efficient grinding with precise classification, all in one single machine. The decisive benefit of the TICM is the narrow grain spectrum with precise separation from 100 µm to 400 µm.
