The present patent discloses an electric grinder, comprising a shell, a motor assembly, a grinding assembly and a dust cover. The motor assembly and grinding assembly are provided in the shell, and an opening is provided at one end of said shell. The dust cover comprises a cover and a counterweight part, and can open or close the opening of the shell under the gravity of the counterweight part. In the electric grinder provided by the present invention, when the opening of the grinder faces downward, the dust cover can open automatically. When the opening of the grinder faces upward, rotating the dust cover can close and engage with the opening of the dust cover automatically. Thus, the present invention prevents the feed opening of the electric grinder from being exposed to air when the user forgets to close the dust cover.

The invention involves a grinder safety cap suitable for medicinal items such as herbs or other consumable substances that may be desirably restricted from children, and which may require grinding and/or homogenizing before ingestion. The grinder safety cap is comprised of a cover shell and base shell, wherein the cover shell fits snugly over an upwardly extending top wall of the base shell. The base shell may have upwardly extending grinding protrusions, having sharp and/or serrated edges, capable of grinding, cutting, or otherwise reducing the particle size of a consumable substance. The cover shell may also have downwardly extending grinding protrusions. A consumable substance may be placed within a cavity or receptacle of the base shell, the cover shell may be placed over the top wall of the base shell so as to close the grinder safety cap, and the consumable substance may be ground by turning the cover shell.

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.
