Process control for production of liquid food

A system for production of liquid food, comprising:

• a food processing arrangement operable to perform a plurality of food processing steps for one or more ingredients to be processed into the liquid food, and
• a computer device which is connected to the food processing arrangement and configured to control the food processing arrangement to perform the plurality of food processing steps,
• the computer device comprising:
• a memory configured to store a control program that comprises a list of instructions configured to cause the food processing arrangement to perform the plurality of food processing steps, wherein the list of instructions comprises command instructions that each allocates a respective food processing step to a predefined control command among a set of predefined control commands, and
• a processor configured to sequentially execute the command instructions in the list of instructions,
• wherein the set of predefined control commands comprises:
• a first start command which is associated, by the processor, with an action of:
• starting a first food processing step that is allocated to the first start command and proceeding, without waiting for the first food processing step to be completed, to a subsequent instruction in the list of instructions;
• a first stop command which is associated, by the processor, with an action of:
• ensuring a termination of the first food processing step that is allocated to the first stop command by commanding the first food processing step that is allocated to the first stop command to terminate without waiting for completion of the first food processing step that is allocated to the first stop command, waiting for a confirmation that the first food processing step has been terminated, and proceeding, responsive to the confirmation, to the subsequent instruction in the list of instructions;
• and
• a second stop command different from the first stop command, the second stop command being associated, by the processor, with an action of:
• waiting for a second food processing step that is allocated to the second stop command to be completed, and proceeding, responsive to determining that the second food processing step has been completed, to the subsequent instruction in the list of instructions, wherein the first stop command is configured to cause the first food processing step to terminate without consideration of status of the first food processing step and the second stop command is configured to cause the second food processing step to verify completion of the second food processing step, and
• wherein the second stop command is executed after the first start command and prior to the first stop command.
