Automated “Toaster” Measures Vegetable Oil Production
Wednesday, May 21, 2008
One of the most important stages of vegetable oil production is when the oil passes through the ‘toaster’ equipment. The toaster is formed with 4 to 10 dishes that hold the flour used during agitation treatment for solvent removal. The weighing process on each flour dish is normally mechanical, where data is sent to a PLC control system. This procedure is now being automated with the implementation of the SMAR TP290 - Position Transmitter 4 to 20 mA electronic position transmitter. It is a completely digital process, comprised by sensor connection to the Toaster dishes and utilizes a rotary magnet that is integrated to a transmitter.
The TP290 - Position Transmitter 4 to 20 mA line position transmitters are sold with the TP301 - Smart Position Transmitter 4 to 20 mA + HART, TP302 - Foundation Fieldbus Position Transmitter and TP303 - Profibus PA Position Transmitter technologies. Argentina currently has five companies using the Brazilian technology, including Molinos Río de la Prata (Santa Fé), Teminal 6 (Santa Fé), Productos de Maíz (Buenos Aires), Aceitera Gral. Deheza (Córdoba) and Bunge Argentina (Córdoba).
