Every production plant has the potential to be a self-sufficient energy supplier and can operate independent from the energy market. This can be achieved with circularities and turning waste streams e.g. biomass like spent grains into useful side streams. Processing biomass directly on site reduce transport costs, transport emission, prevent them from spoiling and supports your own value chain. This waste stream has an enormous potential as a CO2-neutral energy source. To gain this potential an special procedure was been developed. The spent grains are transported after the lautering process to a dryer where the moisture of the spent grains will be reduced. From now on the spent grains are storable and processed whenever needed. If thermal energy is needed for production (boiling or distilling) the dry spent grains are burned to produce heating water or steam. The drying energy comes from a heat pump. The energy source for the heat pump is the glycol return line. The heat pump extracts the energy from the glycol return line to lift it up for the energy supply for the dryer and simultaneous cooling down the glycol stream to pre-run temperature. Means the heat pump replace your cooling plant or support an existing one. Previously the energy and water consumption should be reduced as much as possible e.g. with retrofittable ultrasonic devices at equipment with high cleaning effort. Reducing the amount of cleaning cycles results always in water savings. Get in contact with us to find out more.
