The HD1400 Hot Dog Vending Machine was introduced in October 2003
at the National Automatic Merchandising Association (NAMA) National Expo.
The machine, from LHD Vending, Inc., (Owings Mills, MD, U.S.) uses a
patent-pending technology to refrigerate, grill, and dispense hot dogs.
The unit is designed to serve a grilled hot dog on a warm bun in a plastic
tray in as little as 45 sec.
The HD1400 was developed by engineer Leon Leykin, who is also LHD's
president and CEO. The machine stores the hot dogs in a refrigerated
compartment separate from the buns. When a vend is requested, the hot
dog is cooked with microwave energy to heat it inside while IR energy
heat and crisps it on the outside.
The bun dispenser unit is built into the lower part of the machine
cabinet. When vended, the unit lifts the bun onto a horizontal conveyer.
The hot dog and bun come together after cooking. Consumers view the cooking
process from the moment the hot dog exits the refrigerated compartment,
throughout the cooking, and until the product is dispensed.
After a product is vended and the machine is inactive for 5 min, it
automatically activates an IR self-cleaning process.
The machine can be equipped with a wireless communication system to
report sales, inventory, and technical problems to the operator. The
control system includes an Expiration Date Control function.
The self-diagnostic capability, the use of industry-standard components,
and a modular design are all intended to allow vending operators to more
easily service the unit and make repairs in the field. The machine is
designed to accept most hot dog products and has a capacity of up to
600 hot dogs and 300 buns. Four product selections allow the unit to
dispense sausages, cheeseburgers, kielbasa, and other food items.
