The first cane diffuser ever made in Brazil, installed at Usina Galo Bravo, SP, started operation in 1983. Crushing capacity 3,500 TCD
Second Brazilian cane diffuser installed at Usina Cruz Alta , Guarani Group, in Brazil in 1985. Crushing capacity 8,000 TCD
The need of higher sugar extraction rates encouraged the development of cane diffusers in Brazil. Joseph Arthur Paul Jacquelin a Mauritian sugar technologist with extensive experience in diffuser design and operation was contracted to develop the first Brazilian prototype. Paul moved to Brazil in early 1982 to provide the design of a 3,000 TCD unit. The equipment began operation in 1983 at Usina Galo Bravo, in the Ribeirao Preto region, State of Sao Paulo.
With the start-up of the diffuser in 1983, Usina Galo Bravo increased the crushing capacity from 3,500 TCD to 7,000 TCD, operating the diffuser in parallel to a conventional five 4-roll 30" x 66" mills, both lines with similar throughput of approx. 3,500 TCD, processing the same sugar cane. The diffuser has constantly maintained a Pol% extraction over 98% with a increase of efficiency over the mill tandem between 1.8 and 2%. Two years later Paul was hired to design a second diffuser, this one with a crushing capacity of 8,000 TCD. The unit was installed at Usina Cruz Alta de Olimpia and began operation in 1985. Similarly to the first diffuser this unit has maintained for year a record extraction above 98%.The diffuser was handling the whole factory cane throughput and years later, reached capacities up to 14,000 TCD after the installation of a second drying mill , while maintaining extraction rates always above 97%. The refined sugar produced in Cruz Alta was considered at the top as far as quality (color and ashes) contradicting the common belief that a good sugar quality cannot been obtained with the diffuser because of the higher quantity of impurities entering the process.
Since 1997, the year when Barlou & Associates Importação e Exportação, Ltda. was bought out by Uni-systems, we have retained the property right for the original diffuser technology. In the following decades several improvements were incorporated into the original design. Manufacturing licences for the Uni-systems diffuser technology, were granted to various Brazilian and American sugar equipment manufacturers, among them Arkel, Sermatec, Simisa, Brumazi and Sermasa. Almost all diffusers installed in Brazil today and most of the units in operation in South America and in the United States, were fabricated under Uni-systems’ license.
Uni-systems diffuser is widely know in Brazil and Latin America. We count with more than thirty successful units already installed and commissioned and a few other under construction.
