North American Car Corporation recently designed three new unloading systems for bulk products. One car is equipped to liquify certain bulk products, such as sugar, at the unloading site. The product can then be easily pumped out, reducing handling costs. In another case, a new unloading valve was designed for covered hoppers that handle plastic pellets and resins. Product flow is easier to control and the chance of binding or wedging is reduced. The last car design uses air pressure to discharge the product. The hopper is pressurized to about 15 p.s.i. and then the discharge valve is opened, forcing the product out. The system eliminates moving parts, reduces contamination of the product and reduces handling costs.
