Method for controlling a food handling system

A server configured to control a food handling system comprising a number of food production units, the server comprising:

• a transceiver, a control circuit, and a memory,
• wherein the transceiver is configured to:
• receive process data, wherein the process data is extracted from the food handling system, and wherein the process data comprises parameter values captured via sensors provided in the food production units;
• request user input data by transmitting a user input data request to an operator carried device;
• receive the user input data from the operator carried device, the user input data comprising handwriting text features extracted from handwritten text;
• transmit control data to the food production units;
• compare the handwriting text features of the user input data with handwriting text template features extracted from a handwriting text template to determine a match;
• and
• compare the user input data with reference user input data;
• wherein the control circuit is configured to execute instructions stored in the memory, the instructions causing the control circuit to:
• in response to the match being determined and to the user input data being within a predetermined input range associated to the reference user input data:
• determine the control data based on the process data and the user input data;
• and
• update settings in the food production units based on the control data;
• in response to the match being determined and to the user input data being different from the predetermined input range associated to the reference input data, transmit an alert to the operator carried device indicating that the user input data is out of range, and
• in response to the match not being determined, reject the user input data.
