Pasteurization System

For viscous and highly abrasive organic waste The higher the total solids content of the processed organic waste, the more revenue is generated per ton of organic waste processed through your plant. lncreasing the total solids content of the waste processed from 10% to 20% reduces by 50% the amount of digestate produced. PROBLEM #1: PUMPING TECHNOLOGY Therefore 3 critical problems needed to be solved » Organic waste slurries with a high total solids content are too viscous for centrifugal pumps. » Organic waste slurries contain significant amounts of sand, broken glass or similar highly abrasive components. » Rotary displacement type pumps suffer significantly due to abrasion. » SOLUTION #1: FINSTERWALDER KV20 Ball Valve Pump PROBLEM #2: heating Therefore the following critical problem needs to be solved » The heating of preprocessed slurries in a stirred tank requires permanent mixing to achieve heat transfer. Regular maintenance of mixers and accumulation of impurities cause operational failures and increases loading and heating cycles. » SOLUTION #2: FINSTERWALDER Double-Tube Heat Exchanger Each pasteurization system is sized individually and modular by design, with current reference sizes ranging from 30 to 100 tons/day. The FINSTERWALDER pasteurization system closes the gap between waste handling, pretreatment and the anaerobic digester. Individual design and detailed calculation based on long term trials and a large database.
