A system and method for managing food production, inventory and delivery
in a restaurant by automatically monitoring the types and quantities of
food types that have been cooked and are in a cooked food holding area.
Food holding trays are equipped with radio frequency identification
(RFID) tags, and holding cabinets are equipped with RFID interrogators.
The type and quantity of food items are determined manually or by machine
vision or weighing systems, and the data is stored on the RFID tags and
in a controller. The system manages the use of food items on a first-in,
first-out basis, alerts operators when the inventory of an item is
nearing exhaustion, and alerts operators when food items in the holding
area must be discarded. The system manages movable trays of food no
matter where in the facility they are located.
