The need of higher sugar extraction rates encouraged the development of cane diffusers in Brazil. Mr. Jacqueline, a later founder of Uni-systems, started designing the first unit in early 1982.  The equipment, with a capacity of  3,500 TCD began operation in 1983 at Usina Galo Bravo, in the Ribeirao Preto region, State of Sao Paulo, Brazil. 

 

With the start-up of the diffuser, Usina Galo Bravo increased its 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 and processing the same sugar cane. The diffuser immediately showed a Pol% extraction exceeding 98% with a margin, over the mill tandem of 1.8 to 2% . Two years later Mr. Jaquelin 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 a record extraction above 98% over the years. The diffuser has been handling the total cane throughput of the factory until, a few years later, praks of up to 14,000 TCD were reached after the installation of a second drying mill. The extraction rates were still above 97% at almost 175% of the unit design capacity.  

 

Cruz Alta has always been reknown for its high quality refined sugar (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, Uni-systems, has retained all property right over the original diffuser technology and in the following years, 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 although, at present, Citrotec International is the exclusive licenced partner to construct  Uni-systems diffusers.  For additional information on Citrotec, please see the attached Citrotec Brochure on Sugar-Energy  products.

 

Uni-systems diffuser is widely know in Brazil and Latin America. More than thirty installations have been successful completed and commissioned.
