A large number of biomass residues are produced in agriculture, livestock farming, landscape maintenance as well as in industrial production processes of food production. Examples are bedding material for horses and bedding material from the livestock production in general. In food production, it is a number of residues such as grape marc during the production of wine, apple marc during the production of juice, marc in general during the production of fruit juices and during the production of alcohol, coffee grounds, bakery residues and many more. These products are normally wet and must be disposed of which, in most cases, is complex and expensive. The typical disposal route, i.e. the field, is increasingly restricted which is correct since these residues are to some extent strongly overconsolidated in terms of hygiene. You should think of sewage sludges and fattening farms that increase the risk due to the continuous usage of medication that contaminating substances could enter our food chain. An uncontrolled disposal is associated with an overfertilisation of the grounds and ingress into our ground water.

Our STR biomass drying procedure is not only an interesting economic solution but turns a disposal product into a recycled product which can be re-integrated in different ways into an environmentally-friendly and reasonable cycle. Apple marc is an example for this. The freshly pressed-out marc is a high-quality food but quickly transfers to an intensive and smelly fermentation process within a short period of time. If the juice production is followed by the biomass drying procedure, the wet marc is dried and turned into high-quality animal food. The material to be dried is fully hygienised during the drying procedure and can be used as bedding material, as fertiliser according to the fertiliser law or it can be used for energetic recovery.

By means of our cyclone combustion chamber with multi-functional biomass burner, all types of free-flowing biomass fuels can be burned and used for the generation of hot air for the dryer. This does not only ensure a highly efficient drying procedure but guarantees it at lowest operational costs.
