Chapter 3 Machine description
This chapter gives general information about the Solus
3.1 Purpose of the unit
The unit is designed for the dispose of food waste (organic material only) in a hygienic and ergonomic
way at the source (restaurant or kitchen) with a minimum of logistics and handling of personnel to the
waste storage room.
3.2 Technical specification
The Solus is a standalone unit which reduces the volume of the loaded foodwaste on the spot. The food
waste is loaded on the grid where it falls through. Below the grid is a grinder which reduces the size of
the particles in the food waste. From here the food waste is pumped to a dewater unit where the water
is separated from the solid parts. The water is partly rececycled and the solids are collected in a bin.
The system consist the following parts:

3.3.1 Food waste intake
The maximum intake for each cycle is 16 liters. If more waste is added the water will float through the
overflow opening (1). The food waste inlet is covered with a safetygrid (2) which prevents a human arm
to reach into the grinder (5). On the safetygrid there are hit bars (3) to easy emptya plate (only one
hand needed). The grid also functions as a guide for the food waste to slide along the optional magnet
(4) which is situated at the far inside of the food waste inlet. This magnet will hold cutlery (metal) to
prevent the system against damage. There is a safety sensor (reed contact) (7) which detects if the
safetygrid is closed before starting a cycle.
