(Posted June 25) - Seaga Manufacturing Inc. has announced plans to introduce an updated glassfront cold beverage machine this fall. Produced by its Vendtronics unit, the new "Quantum 5100" offers first-in, first-out loading and high capacity. The machine features an adjustable tray delivery system able to accommodate cans or bottles up to 24 fl.oz., in any combination of packages whose maximum diameter is 3 ins. or less. Its five reinforced metal product trays are 10 columns wide and accommodate 10 cans or bottles per column, for a total capacity of 500. The "Quantum 5100" is fully insulated for efficient operation, and fitted with a health control that permits it to vend milk-based and other perishable.beverages. It incorporates a heated thermal glass product window to prevent condensation, and the cabinet interior is illuminated to enhance the product display. Its slide-out refrigeration system can be removed in minutes, and it is supplied with a three-point locking system and steel T-handle lock assembly. A novel feature of the "Quantum 5100" is its display and loading system. Cans or bottles are simply inserted into each column from the front; the last to be loaded rests on a detent at the forward edge of the tray. The packages vend from the rear edge, but the last to be loaded remains in place on its detent, insuring an attractive display at all times.
