Abstract: The present invention is an improved method to grind coffee where grinding speed can be adjusted either on demand or according to a programmed profile. By lowering the rotational speed of the grinding burrs, the user can insure more consistent particle size for types of coffee or methods of brewing where it is desirable, or dramatically increase speed for greater productivity. By incorporating a load cell, the grinder is able to identify coffee brewing device and deliver portioned ground coffee according to program settings or user input. The device also features an improved hopper design to reduce waste and ease whole bean removal. More importantly is a new method to calibrate the distance between the grinder mills and to automatically adjust grinder particle size so that a given numerical value is consistent for each grinder and every user.

Abstract: The ability to grind coffee as needed and in the precise quantity required is key to ensuring quality because once ground it begins to oxidize rapidly and lose much of its flavor and aroma. One embodiment of this invention converts existing coffee grinders into portion controlled grind-on-demand devices, grinding only what is required for immediate use. When used with a remote, wireless activation device to select the portion desired, either by time or by weight, this conversion is possible without any grinder modifications. Additionally, this invention collects usage, date and time information for amount of coffee ground independently from the remote activation device. Inventory, quality and consumption data can be tracked via the internet in real time, independent from its portion control capabilities. Finally, as a wireless device it can collect information from other wireless devices, adjusting the quantity of ground coffee delivered to maintain quality.
