If you need to process feathers or hog hair into a high-quality feed meal that contains a minimum of indigestible proteins, the Haarslev Vertical Hydrolyzer is an extremely effective way to do it.

The fibers disintegrate when pressure-cooked at high temperatures under controlled conditions. Full control and the right balance between pressure and retention times – with your input material only very briefly exposed to high temperatures – help you achieve feed outputs of the quality you require.

These units are available with processed raw material capacities up to 10 metric tons per hour. After hydrolysis, your raw material can be dewatered effectively using a screw press or decanter centrifuge, and then dried.
