Introducing the Bosch Projects Chainless Diffuser
Although diffusers are widely accepted to offer generous
advantages over milling (lower capital cost; lower
maintenance costs; 50% less power consumption; improved
pol extraction), conventional diffusers have never really
become accepted worldwide as superior technology, partly
because they don’t offer the same flexibility of capacity as
mills.

Since 2008, the Chainless Diffuser has become the most
innovative technology available for extraction plants. The
Chainless Diffuser is modular in design, meaning that its size
(and capacity) can be increased during the period of a single
offcrop.
3D CAD Model of the Chainless Diffuser
The Chainless Diffuser doesn’t use diffuser chains for the
transport of cane inside the diffuser. At a cost of about
$1,000 per metre, these chains are a significant component
in the cost of a new diffuser. By eliminating the need for
chains, the Chainless Diffuser is between 20 and 30% more
cost effective than conventional diffusers.

In recognition of the benefits of this new technology, 14
Chainless Diffusers have been designed since 2008 and 11
are currently in operation. HPCL have 150 tch units at two of
their plants in India while Raizen, the world’s largest cane
sugar company, has an 875 tch unit in Brazil (the world’s
largest diffuser). And the 150 tch units can readily be
expanded to the same capacity as the Brazilian giant
diffuser! This is the reality of the modular Chainless Diffuser.
The latest success is at Ubombo Sugar in Swaziland where
extraction rates of 98% are regularly achieved. The diffuser
at Aguai in Bolivia will start-up in 2012, and Bosch Projects
are in discussion in Australia for a diffuser in a greenfields
plant of 275 tch
