    Auto-fill High Output Temperature Controlled Humidifier

    Auto-fill High Output Temperature Controlled Humidifier

    This project turns a 5 gallon bucket into a high capacity (4 gal/day), automatic fill humidifier. The bucket serves as a reservoir for the water and also as a mounting platform for the parts required to operate the humidifier. Water heated to a know temperature will transfer a predictable amount of water vapor to an air stream of a known temperature and humidity (wet bulb temperature). We use this property to develop a highly controlled humidifier using a temperature control to sense water temperature and control the heater, tank deicer for heat, and a CPU fan for air flow. We also add a toilet fill valve to the assembly to allow for automatic fill of the humidifier. NOTE: Pictures shown from the first build do not include complete safety features including: electronics enclosure, GFCI protected circuit / outlet, and terminal covers. Please take care when wiring and using this design to ensure personnel and property protection.

    Vacuum Material Handler

    Vacuum Material Handler

    This material handler design, created at this year's Farm Hack in Davis, CA, consists of a vacuum system to lift grain from a truck into to hopper below the vacuum unit. The vacuum unit is located above the machine of intended use (a grain cleaner for example). Once the vacuum hopper fills up, the vacuum is turned off and then a gate at the bottom of the vacuum hopper is opened and the grain falls down into the hopper of the grain cleaner. Areas left for research include: vacuum type, vacuum hopper geometry, vacuum hose type, automatic shut-off to prevent vacuum motor overheating, and dust safety considering static electricity. Vacuum systems like these are currently used in wood production and water related industries.

    Outside Air Exchange Control

    Outside Air Exchange Control

    This tool demonstrates the use of two thermostats to provide a control system for an air exchange fan that draws cold outside air in to cool a storage room for winter crops. The control essentially provides a differential temperature control which may also be applicable to other processes (curing, solar hot water, etc.)

    shipping container post-harvest shed/commercial kitchen

    shipping container post-harvest shed/commercial kitchen

    This project turns a 40' insulated shipping container into a fully operational post processing station and cold storage unit as well as a commercial kitchen for value added processing. This project can be built in under $10,000 and combines several readily available technologies such as solar-hot water systems and the cool-bot so that a farmer can process, add value and store produce from a small farm without needing to pull building permits or worry about long term tenure.
