Product Description The ARO Slow Feeder™ is a compact, rechargeable coffee bean feeder engineered to control the rate at which beans enter the burrs of your grinder. A variable-speed motor and controlled spiral feed system work together to gradually meter whole roasted coffee beans into the grinder, instead of dumping the full dose into the burr chamber all at once. The patent-pending ARO Slow Feeder™ is designed to keep your grinder under a lighter, steadier load for a smoother and more consistent grinding process. By introducing beans more gradually, the Slow Feeder tightens particle-size distribution, reduces fines and boulders, improves espresso puck uniformity, and produces cleaner filter brews with greater clarity. This rechargeable version adds USB-C charging, an internal rechargeable battery, automatic jam recovery, a built-in LED status light, and 5-minute auto shutoff if left running. Rare-earth magnets and stainless steel alignment pins make assembly precise and repeatable, while the modular grinder adapter system allows compatibility across a wide range of grinder models. Key Features Patent-Pending Design: The ARO Slow Feeder™ is the subject of pending utility and design patent applications covering functional and ornamental aspects of the product, including the overall device, bean-feeding architecture, and product design. USB-C Rechargeable Battery: Powered by a long-lasting internal lithium-ion battery, it provides approximately 6 to 8 hours of total motor runtime, or roughly 2 to 3 months of typical home use. Recharge conveniently with any standard 5V USB-C power source. Variable-Speed Feed Control: Precisely control the rate at which beans enter the burrs. Maintain consistent burr loading throughout the entire grind to reduce particle-size variation, heat, and load on your grinder. Set your preferred speed once, then use the power button to start and stop each feed cycle. Auto-Reverse Jam Recovery: The Slow Feeder monitors resistance in the feed mechanism. If resistance is detected, the LED flashes 3 times and the spiral feed plate briefly reverses before resuming forward feeding. This clears potential jams while reducing unnecessary strain on the motor. LED Status Indicator: The built-in LED gives quick, easy-to-read feedback for power, charging, full charge, low battery, auto-reverse jam recovery, and battery protection status, so you always know exactly what the feeder is doing. 5-Minute Auto Shutoff: If left running, the feeder automatically powers off after 5 minutes to preserve battery life and keep your workflow worry-free. RDT Compatible: Works with the Ross Droplet Technique, allowing lightly misted beans to move smoothly through the feed path without sticking to the feed plate or getting trapped in the feeding mechanism. Ultra-Compact Design: Engineered to fit in the palm of your hand, the Slow Feeder adds controlled electric feeding without the bulk. Its compact, removable design makes it quick and easy to move from grinder to scale, back to grinder, or between compatible grinders. Magnetic Alignment System: Neodymium magnets and stainless steel pins ensure precise, repeatable alignment and a secure fit. Detach the Slow Feeder for dosing, cleaning, or quick-swapping between compatible grinder adapters. Dose Directly on a Scale: Remove the complete feeder from the grinder adapter and place it directly on your scale to weigh beans into the hopper. Once loaded, snap it back onto the adapter using the magnetic alignment system for a clean, repeatable workflow with no separate dosing cup required. Low-Profile Cap and Silicone Bellows Included: Cap the hopper to keep out dust and debris, or use the included silicone bellows after grinding to purge retained grounds from the grinder for a cleaner, more consistent workflow. Doubles as a Single-Dose Hopper: Remove the feeding mechanism and connect the hopper directly to the adapter to bypass slow feeding when desired. This allows the full dose to feed direct
