The First Bosch Projects Bagasse Diffuser
15m Wide Dedini - Bosch Chainless Bagasse Diffuser at the Meridiano factory in Brazil.
The start of this year’s Brazilian cane milling season has
brought with it the start-up of the first Bosch Projects
Bagasse Diffuser at Usina Meridiano in Brazil.
The factory was built and commissioned in 2011 and the
diffuser ran for two seasons as a cane diffuser. Last year the
owners, Noble Group, employed Bosch Engenharia to do a
study and then implement the Bagasse Diffuser extraction
system on their Meridiano factory. This involved installing a
100 inch Dedini mill and intercarriers preceding the diffuser.
This has increased the capacity of the front end by 40% and
also provided the process house with the option of using the
high purity juice from the first mill to produce sugar and the
low purity juice from the diffuser to produce ethanol. The other,
less obvious benefit, is that the first mill adds approximately an
additional 2 units to the cane Preparation Index (PI). This has
far reaching consequences in Brazil as most of the preparation
devices preceding diffusers are not operated to provide
sufficient cane preparation for optimum sucrose extraction.

Bosch hired to optimise Skeldon factory
The Skeldon sugar factory, which was commissioned in
August 2009, was hailed as the boon to the survival of
Guyana’s sugar industry. The factory has since been plagued
by numerous problems and unable to function as expected.
Designed to produce 110,000 tonnes of sugar per annum,
production was 33,237 tonnes in 2010 and 29,410 tonnes
in 2011. This caused the government to look for a company
to address problem areas in the factory. Looking no further,
Bosch Projects was hired by the Guyana Sugar Corporation
(GuySuCo) to help ensure that the Skeldon Sugar operates
at full capacity.
Bosch Projects designed modifications to the factory’s three
main aspects: the bagasse plow, the conveyor system and the
condensate tank.
They intend to rectify most of the factory’s design flaws in the
outcrop period. The expected completion date is before the
first crop in 2013.
