The K+G Wetter GmbH Mixer Automatic Grinder includes a mixer shaft which is located above the feeder worm. The reverse running feeder worm supports the mixing paddle so that the product to be mixed is always fed from the bottom of the hopper into the mixing circuit. Clusters of seasoning and the creation of ‘dead spaces’ are completely prevented to ensure a smooth operation. The two-worm principle includes perfectly coordinated rotational speeds for careful material feed, a clear cutting pattern for the best cutting results.
