An electronic grinder powered by a smartphone has an electronics housing removably attached to a container section. The electronics housing has a motor and a microcontroller powered by a smartphone connected by a universal serial bus connector. The container section is sealed at the top by an openable, swivel-mounted cap. The motor has a blade that extends into the container section. The blade connected to the motor by a magnetic connection and the blade is configured to grind material disposed in the container section when the container section is closed.

A tamping augur may be controlled in various ways to obtain a consistent fill height and uniformity in the distribution of coffee grinds in a portafilter.

A coffee grinder with a weight device to dose ground coffee includes an electric motor, a grinder group driven by the electric motor and housed inside a grinding chamber, a feed hopper for feeding coffee beans to the grinding chamber, a delivery channel for delivering ground coffee to a support fork of a filter-holder of the ground coffee, a load cell mechanically connected to the fork, and a microprocessor that controls the operation of the motor to determine a desired final dose of ground coffee inside the filter-holder. The microprocessor contains control firmware which, when weighing a new dose of coffee: (a) activates a weighing program that activates the electric motor so that the grinder group grinds the coffee; (b) continuously controls, with the load cell, the detected weight of ground coffee reaching the filter-holder; and (c) shuts the electric motor down when the detected weight reaches a desired value.

Automatic process for calibrating the single and double dose of ground and dispensed coffee by means of a specific grinder-doser integrating a weighing device with a load cell. The process is automatically and steadily carried out during the ordinary activity, with no interruptions, adapting the grinding time according to the actually detected grammages, in order to get closer as much as possible to the desired grammage in any use condition. The process, after a preliminary phase for temporary configuring the desired grammages and the grinding time, conceives self-calibration cycles continuously repeated, each of them comprising three sequential phases: a first phase for automatically checking the dispensing with progressive weight detections, a second phase for automatically processing the detected data for determining the correct grinding time, a following third phase for the automatic setting.

Grinders, analyzers, and related technologies are described herein. The grinders can hold foodstuff that is periodically ground. The analyzers can analyze the foodstuff to determine information about the state of the foodstuff. Algorithms can be used to determine how to process the foodstuff, how to use the foodstuff, and/or when to discard the foodstuff. The grinder can be a portable, rechargeable electric coffee grinder configured to monitor the freshness of the coffee beans. When coffee beans become stale, they can be discarded and the coffee grinder can be refilled with fresh coffee beans.
