Dengshang Home Biogas Plant Waste Chopper/ food waste disposer makes a great addition to the feed preparation sump/sink unit of home biogas plants.

Dengshang home biogas plant waste chopper/macerator is suitable for home biogas plants. It is fitted in at the start of the feed supply pipe into the digester tank.

The purpose of this unit is to ensure that all the feed materials entering the digester are chopped up as small and as fine as possible. When used as  a home biogas plant waste chopper macerator in the Sink/Digester Feed the DSB-390A will increase the amount of biogas produced. It also reduces the risk of digester blockages due to the fine chopping of the waste fed through it.
