Fermentation monitoring and management
A fermentation monitoring system may measure the weight of a fermenting product to determine the progress of fermentation. The weight of a fermenting batch may decrease as carbon dioxide is given off, and a continuous or periodic weight measurement may be used as a control input to a fermentation system, which may adjust temperature to control fermentation or detect that fermentation is not progressing as expected. Such a system may be to use a weight scale attached to a fermentation vessel and have a control system capable of adjusting the temperature of the fermenting contents. One implementation may have a scale mounted inside a temperature controlled fermentation cabinet.
1. A system for monitoring a fermentation process in a fermentation vessel, said system comprising:
a control system;
a fermentation system housing a scale configured to receive said fermentation vessel and having an output connected to said control system;
a hardware platform comprising a computer processor; said control system executing on said hardware platform configured to:
determine a starting weight value of said fermenting vessel;
determine a starting time for said fermentation process using said fermenting vessel;
receive a weight measurement representing a weight of said fermenting vessel at a time which is sometime after the starting time of said fermentation process, using said scale;
determine a calculated anticipated weight for said fermenting vessel, said calculated anticipated weight being determined at least based on said starting weight value and said starting time;
compare said weight measurement to the calculated anticipated weight; and
in response to determining that said calculated anticipated weight is a predetermined expected final weight, determine that said fermentation process has completed based on said predetermined expected final weight.
2. The system of claim 1 , said control system further configured to:
determine a target temperature;
transmit said target temperature to a temperature control circuit, said temperature control circuit controlling a temperature of said fermenting vessel.
3. The system of claim 2 , said control system further configured to:
in response to determining that said calculated anticipated weight is not said predetermined expected final weight, determine a deviation from said calculated anticipated weight.
4. The system of claim 3 , said control system further configured to:
adjust said target temperature based at least in part from said deviation from said calculated anticipated weight.
5. The system of claim 4 , said control system further configured to:
transmit a recipe description to a recipe analyzer; and
receive a fermentation expression for said recipe description, said fermentation expression being used to determine said calculated anticipated weight.
6. The system of claim 5 , said recipe analyzer being a remote device, said system having a network interface configurable to connect with said remote device.
7. The system of claim 1 , said calculated anticipated weight being expressed in a fermentation function, said fermentation function being a function having a time input.
8. The system of claim 7 , said fermentation function being received from a recipe analyzer.
9. The system of claim 1 , wherein the fermentation system further comprising:
a temperature controlled compartment configured to house said fermentation vessel, said temperature controlled compartment comprising a temperature control circuit connected to said control system.
