EXPANDERS

For soybeans, sunflower seeds, rapeseed, corn, cottonseed, rice bran, etc.

Capacities: from 200 tpd to 4,000 tpd.

TNL Tecnal was the first company in the world to design and manufacture, in 1978, expanders for application in seed preparation for oil extraction. Since then, TNL Tecnal has been continuously innovating and updating its Expanders.

Years of experience have led TNL Tecnal to have the most reliable and efficient expanders in the world, with more than 500 expanders running successfully in more than 200 customers around the world.

TNL Tecnal Expanders provide maximum efficiency and minimum wearing, thus low maintenance cost.

TNL Tecnal expanders will bring great benefits to you:

• Increase of 30% to 50% in the extractor´s capacity because of the combination of two factors: the bulk weight of expanded meat (0.55t/m3) is higher than the bulk weight of flakes (0.35t/m3), thus more material will fit in the same extractor; the extractor can run faster as the washing time for expanded meat is shorter;
• Better percolation rate because the material will be more porous;
• Less fines going to the extractor;
• Less residual oil in the meal;
• Less solvent dragging to the DT, hence live steam consumption is reduced;
• Higher miscella concentration, so steam demand for evaporation is much lower and therefore distillation capacity is increased considerably;
• Less solvent consumption per ton of seeds;
• Less steam consumption per ton of seeds;
• Possibility of processing thicker flakes;
• Possibility of using non homogeneous seeds, as the expander will macerate the meat and will make it homogeneous;
• Deactivation of soybean ANFs (anti nutritional factors), sustainably, due to proper heating;
• Decrease of non-hydratable phosphatides;
• Increase of quantity of phospholipids in the extracted oil , thus, more gums for lecithin production or more gums to be converted into oil by enzymatic degumming;
