A electronic grinder includes a main body and a grinding and dispensing chamber. The top of the main body open but covered by a cap. The main chamber includes a motor connected to a magnetically attached removable blade and propeller. The blade and propeller extend into the chamber when the grinder is assembled. When the cap is closed, the blade and propeller grinds material placed in the chamber and pull air down toward the blade and propeller. When the cap is opened, the blade and propeller function as a fan to generate airflow toward the top of the chamber to dispense ground material out of the chamber. The grinder can also include a microcontroller, a communications device, an infrared volume sensor, a scale, an audible buzzer, a vibration buzzer, and one or more sanitizing LED lights.

A grinding machine for a coffee, spices or another granular food includes a couple of grinding disks and wherein the couple of grinding disks rotate during a grinding. Among many advantages, the grinding machine provides a lower energy consumption and a lower noise emission at a same ground product rate.

A grinder for plant substances includes a first surface and an opposing second surface that is separated from the first surface by a first longitudinal gap so that the first surface and the second surface define a receptacle within which a plant substance may be received. The second surface includes holes through which ground pieces of the plant substance may pass and at least one of the first surface and the second surface includes bumps that extend into, but not across, the receptacle. The bumps encourage rolling friction between the plant substance and the bumps so that the plant substance is ground into pieces small enough to pass through the holes.

An herb grinding and rolling apparatus configured to provide availability of all of the elements required to facilitate the grinding of herbs and dispensing into a paper for subsequent rolling and smoking. The present invention includes a body wherein the body is formed from a first section, a second section and a third section. The three sections are foldably coupled so as to move the body between a folded position and an unfolded position. The first section includes an herb grinding compartment having an interior volume and an herb grinding plate. The second section and third section are configured to receive, retain and dispense sheets of paper suitable for use in rolling ground herbs. The paper includes perforation seams at one end thereof to produce a desired shape for an end of a rolled paper. The herb grinding compartment includes a funnel formation in the sidewall thereof.

A coffee grinder having at least a flow channel that directs the ground coffee particles conveyed from the outlet of the grinder in order to transfer them to a container, and its inlet positioned right below the grinder outlet and connected to the grinder such that it can rotate according to the channel inlet axis that passes through the center of the inlet, and a motion control motor that successively moves the flow channel at the inlet axis in opposite radial directions in a suitable amount and frequency in order to prevent the sticking of the ground coffee particles located in the flow channel to the flow channel. A coffee machine having such a coffee grinder is also disclosed.

A coffee machine, including a grinder configured to grind coffee beans, and a coffee machine made to remove waste, such as chaff, from a separation area, where the waste such as chaff is separated from ground beans. The coffee machine includes a first grinder configured to grind the coffee beans by grinding, a separation area where the waste is separated from the ground beans ground by the first grinder. And, the waste from the separation area is cleaned by wind pressure while the first grinder is in a stop state.
