STAINLESS STEEL SILO UNLOADER

ICE BINS IN THE PAST . . . The weakest part of most ice systems has been the ice bin and its unloading system. Bins did not have smooth inside walls. Bins were not sanitary nor easily cleaned. Since ice freezes, fuses, arcs, bridges and does everything but flow, and since force was required to move it, bins were hit with mallets in an attempt to unload them, severely damaging Bin Walls in the process. The most beautiful cubes were beat up & crushed trying to get them out of the bin.

Now, KEYSTONE OFFERS . . . ¬ A clean, sanitary, “U.S.D.A. Accepted” Ice Silo

built with stainless steel.

¬ Inside of Silo Wall is smooth. All fasteners are on the outside of the silo.

¬ Rotating Distributor in top of silo distributes ice cubes in uniform layers. This makes unloading ice cubes much easier.

¬ Knee wall at top of Reclaim Floor allows sweep augers to undercut all ice cubes and thus pre-vent bridging in the silo.

¬ Keystone’s 180 & 280 Silo Unloaders are “gentle as lambs”, but tougher than cubes, and unload ice cubes at the touch of a button! “Beautiful ice cubes are kept looking beautiful.”

¬ Keystone’s “Heavy Duty” Stainless Steel Bottom Unloaders replace mallets.

¬ Stacking Ice Cubes “up” in a Keystone Ice Silo instead of “out,” saves valuable floor space for other operations.
