A MACERATOR

摘要

The invention relates to a macerator, of the type used for disposal of assorted or fibrous products and biological waste, typically as used in sluicerooms in hospitals or care homes. In one aspect the macerator comprises a chamber and Nd, which together in use define a sealed volume for receiving items to be macerated. A chopper is located in the chamber and an inlet is provided for water; and a drain for removal of macerated product. A means is provided for closing the lid to the chamber using a non-contact control system. Ideally the non-contact control system includes a proximity sensor, such as an infra red (IR) sensor for detecting a user or operators hand. The invention overcomes previous problems of having to close the lid by hand and thus reduces the risk of cross contamination. In another aspect an improved chopper and chopping cycle helps to reduce noise and water and energy requirements.
