TOUCHLESS TIMER AND PRODUCT MANAGEMENT FOR FOOD HOLDING DEVICES
The devices, methods, and algorithms of the present disclosure provide a hot food holding cabinet to detect the presence and uniquely identify a plurality of food holding trays within a plurality of food holding locations within a hot food holding cabinet. There can also be multiple, separate food holding cabinets that are linked together. Timing and other functions related to the storage of the food holding trays are initiated automatically, without any manual input from a user. This allows for the automated initiation and tracking of product quality parameters by the cabinet computer. The parameters can include product timers and holding profiles, and whether the food holding trays are removed, transferred between bins in a single cabinet, or transferred between separate cabinets.
1 . A system for storing food products at heated temperatures, comprising:
a cabinet;
a tray for holding the food products, wherein the tray has a transceiver connected thereto, and the transceiver has identity information relating to the tray;
a storage bin in the cabinet for receiving the tray, wherein the storage bin has a reader therein, for reading the information from the transceiver;
a heater in the storage bin, for supplying heat to the tray; and
a processor in the cabinet,
wherein, after a user places the tray in the bin, the processor receives the identity information from the reader, and performs at least one of the following functions: registering the tray to the bin, initiating a timer associated with the tray for the time that the tray is within the storage bin, initiating a change in the temperature within the bin by changing an amount of power supplied to the heater, prompting a user for input, and initiating an audible or visual is alarm or displaying visual indicators.
2 . The system of claim 1 , wherein the processor performs the functions automatically after the user places the tray in the bin, without any further input from the user.
3 . The system of claim 1 , wherein the bin is a plurality of bins, each having a reader and a heater associated therewith.
4 . The system of claim 1 , further comprising a user interface for displaying information relating to the tray and/or the bin.
5 . The system of claim 4 , wherein the processor is three separate processors, one each associated with the reader, the user interface, and the heater.
6 . The system of claim 3 , wherein the processor further performs the function of determining whether the user has moved the tray from one of the bins to another of the bins.
7 . The system of claim 6 , wherein the processor initiates the timer, and if the user has moved the tray from a first bin to a second bin, the processor transfers information associated with the timer from the first bin to the second bin.
8 . The system of claim 1 , wherein the transceiver is a read-only device.
9 . The system of claim 1 , wherein the cabinet is a plurality of cabinets, wherein each of the cabinets has a bin therein, and a heater associated with the bin.
10 . The system of claim 9 , wherein the processor further performs the function of determining whether the user has moved the tray from a bin in one of the cabinets to a bin in another of the cabinets.
11 . The system of claim 10 , wherein the processor initiates the timer, and if the user has moved the tray from a first bin to a second bin, the processor transfers information associated with the timer from the first bin to the second bin.
12 . A method of storing food products in the heated system of claim 1 , comprising the steps of:
placing the tray into the storage bin;
reading the identity information from the transceiver with the reader;
using the identity information to perform at least one of the following steps: registering the tray to the bin, initiating a timer to track the time that the tray is within the bin, initiating a change in the holding temperature within the bin by changing the amount of power supplied to the heater, initiating a holding profile for the tray, prompting a user for input, and initiating an audible or visual alarm or displaying visual indicators.
13 . The method of claim 12 , wherein the storage bin is a plurality of storage bins, each having a reader and a heater associated therewith, the method further comprising the step of determining whether a user has moved the tray from a first bin to a second bin.
14 . The method of claim 13 , wherein a processor initiates the timer, and if the user has moved the tray from a first bin to a second bin, the processor transfers information associated with the timer from the first bin to the second bin.
15 . The method of claim 12 , wherein the cabinet is a plurality of cabinets, each of the cabinets having a storage bin, and a heater and reader associated with the storage bin, and the method further comprises the step of determining whether a user has moved the tray from a first cabinet to a second cabinet.
16 . The method of claim 15 , wherein a processor initiates the timer, and if the user has moved the tray from a first bin to a second bin, the processor transfers information associated with the timer from the first cabinet to the second cabinet.
17 . The method of claim 12 , wherein the transceiver is a read-only device.
18 . The method of claim 12 , wherein the wherein the performing step is executed automatically after the user places the tray in the bin, without any further input from the user.
