Paddle Agitator

Paddle Mixers handle substrates high in fibrous material and solid matter. Paddle Mixers are slow moving agitators operating at approx. 10 rpm. A single shaft with welded on fixed pitch paddles faces along the radius towards the middle of the digester. With each turn the paddles cross the complete volume of the digester making sure that the biomass is properly mixed and fresh substrate is well-dispersed.  Even at a high dry substance content layer or crust formation is minimized with paddle blades reaching above the liquid levels of the digester. Paddle mixers can handle a solid content of up to 14%. Fibrous material, such as grass silage is easily taken in and homogeneously distributed.
