Abstract

Food service workers prepare a number of items throughout the day at a food counter, so the workers may need to track process steps for entirely different processes that are running concurrently. For example, the worker may need to remove a pizza from an oven one moment, and remove breadstick dough from a refrigerator one minute later. A programmable weighing scale guides users through process steps of a process, and tracks completion time of process steps for multiple processes, and alerts a food service worker when a next step in one of multiple, concurrently running processes needs to be completed. Because data stored for each process can be selected throughout, for example, an entire working day, the controller of the weighing scale can track timing requirements for each step of each process. The weighing apparatus is independent of other apparatuses used in completing the process steps (e.g., refrigerators, ovens, mixers, etc.), so it can track process steps that involve various apparatuses that may be needed to complete the processes. An alert for one process step associated with one process can be presented within the duration of an entirely different process step for an entirely different process.

7. The weighing apparatus of claim 1 further comprising a database for storing process files.

8. The weighing apparatus of claim 1 wherein said weighing apparatus guides a user through the performance of process steps related to the preparation of a food item to be made available for purchase by customers.

9. A system for creating and directing processes that use a plurality of perishable items of interest, comprising:

a weighing apparatus, said weighing apparatus further comprising;

a display,

a main interface presented on said display, said main interface having a plurality of page presets,

at least one item preset associated with each of said plurality of page presets, said at least one item preset associated with a perishable item of interest and displayable on said display,

a process control interface associated with each of said item presets for said plurality of page presets, said process control interface presented on said display upon selection of an associated item preset, said process control interface having a plurality of selectable process steps that include process data relating to a process involving a perishable item of interest, said process data contained in an editable process file that includes;

(a) product identifier data,

(b) process step identifier data for each of a plurality of process steps for preparing said perishable item,

(c) start time data for a process step,

(d) duration or end time data for a process step; and

a controller and associated software configured to direct said process defined by said process steps, said controller utilizing said process data of said process file;

(1) to guide a user through performing a plurality of process steps for each of a plurality of processes;

(2) to compare said start time data and said duration data for each of said process steps to determine when to provide an alert; and

(3) to provide during a start time and an end time for a process step of a second one of said plurality of processes an alert to a user of said system within the duration of a process step for a first one of said plurality of processes;

a means for creating process files; and

a database of process files in communication with said controller and associated software, each process file containing process data for a process that may be directed by said weighing apparatus.

10. The system of claim 9 wherein said main interface is defined at least in part by a structure file, said structure file being editable and including data for defining the structure of at least said main interface.

11. The system of claim 9 further comprising:

a mapping file associated with said presets.

12. The system of claim 11 further comprising:
