SCRAPER CHAIN HOPPER

This heavy duty in-feed hopper is used for feeding an Anaerobic digestion plan and is one of a pair recently completed. 

The hoppers are part of a project where out-of-specification vegetables from a packhouse or bypassed in the field will be used to generate electricity for supply to the site and surplus for the grid.

The digester will need a constant flow of vegetables and also maize to maintain 24-hour a day operation

To handle the daily load the two 130 cubic metre capacity hoppers had to be massive – 19 metres long, four metres wide and four metres high.    The hoppers are fitted with twin scrapers not hauled by rubber belts as with conventional intake hoppers but by chains resembling those used on a ship’s anchor.

The hopper is modular in design so it can be built to customised lengths.

It is constructed in mild steel and the galvanised for a more lasting finish.
