"Intecnial is the company who supplied the whole solution to the Argentina factory. The motors run equipment called Dissolvent Toasting machine (DT), "Two of the 650 Hp motors are going to the T6 Industrial company and one 850 Hp motor is going to the Oleaginosa San Lorenzo company", states Roberto Carlos Coradini, WEG sales analyst. Both enterprises are a part of the commissioning of the soybean processing units, which will start its production in March 2005.

These motors are produced in Europe and commercialized in Brazil through WEG Máquinas. "These motors must be explosion proof, since they will be exposed to a risk area in an environment with solvent (hexane),¿ states the engineer Cláudio Fleig, technical advisor of the electrical division of Intecnical.

"Explosion proof medium voltage motors are manufactured at the WEG unit in Portugal (WEG Euro) which has technology and certification for the manufacturing of this line¿ explains Coradini.

The Oleaginosa San Lorenzo is planning to process 10 thousand tons of soybeans per day and the T6, 14 thousand. According to Saulo Ramos, Intecnial Oil Division Manager, the soybean processing industry can obtain, besides the standard products (oil and bran), also the husk and soy lecithin. "In Argentina, the main production is the bran, due to this the companies need the expansion¿, he explains.

"The product process involves preparing soybean seed into flakes and it is then sent to equipment called an Extractor, in this machine the flakes join to a specific solvent (hexane). One part of the hexane extract the flakes oil, forming a liquid solution called mix (oil + hexane); the part which stays impregnated to the flakes forms a mass (bran + hexane + humidity + residual oil) which goes to Dissolvent Toasting machine (DT), where the hexane solvent is separated from the bran by evaporation. Besides the separation of the hexane from the bran, it must be toasted in order to eliminate some enzymes. "That is how the equipment received it's name: it removes the solvent (Dissolvent) and toast (Toasting)", explains the engineer Paulo Paraíso, from the State University of Maringá, in Paraná State (Brazil)

These WEG motors will be installed inside the DT's machines supplied by Intecnial to the Argentinean companies.
