A bean grinding machine with a quick detachable grinding base comprises: a casing; a box body installed within the casing; an upper side the box body having an inlet for receiving external objects to be ground; a lower side of the box body having a lower opening; a grinding disk installed within the box body and between inlet and the lower opening of the box body; the grinding disk being a circular structure with a hollow center portion; an installing unit installed at a lower opening of the box body; and a grinding base installed with a grinding head; the grinding head being positioned within the grinding disk; the grinding base and the grinding head do not rotate; and a gap being formed between grinding teeth of the grinding head and grinding teeth of the grinding disk; and an upper side of the gap is connected to the inlet.

Coffee grinder-doser apparatus (1) with removable grinding chamber for extraction (10), with fast release; the proposed solution makes the grinding adjustment independent of the access to the grinding chamber and makes maintenance easier for the operator. An interface flange (113) is provided which is interposed in univocal position between the adjusting ring nut (115) and the fixed structure (112) of the chamber, which flange makes the coupling indirect of the ring nut (115) and of the extractable group (101) to said fixed structure, being screwed into said flange which is instead slidingly inserted. The locking involves a hooking and releasing system of fast and tensioned type, by means of levers (102) with cam tooth (123) mounted externally on said interface flange, which engage hooking the head of respective tie-rod groups (106) with elastic spring, putting them in traction, which are joined to said fixed structure of the chamber.

A coffee grinding machine includes a hopper loaded with coffee beans, a grinding unit suitable for grinding the coffee beans supplied from the hopper in such a way to obtain ground coffee, a delivery conduit connected to a body of the coffee grinding machine in communication with the grinding unit to deliver ground coffee and a fast coupler/uncoupler suitable for providing a fast coupling/uncoupling of the delivery conduit with/from the body of the coffee grinding machine.

A bean grinding device and a bean grinding coffee machine including the bean grinding device the bean grinding device includes a grinding assembly and an adjusting assembly; the grinding assembly includes a bean grinding chamber, an outer grinding wheel, and an inner grinding wheel; the outer grinding wheel and the inner grinding wheel are disposed inside the bean grinding chamber; the adjusting assembly includes at least two stages of adjusting mechanisms; the at least two stages of adjusting mechanisms includes a first adjusting mechanism and a second adjusting mechanism; the first adjusting mechanism and the bean grinding chamber are connected by means of a first track; the second adjusting mechanism and the outer grinding wheel are connected by means of a second track; and positions of the first adjusting mechanism and the second adjusting mechanism are relatively fixed in an axial direction.

A electronic grinder includes a main body removably attached to a grinding and dispensing chamber. The top of the main body is sealed by an upper cab and the bottom of the chamber is sealed by an openable lower cap. The main chamber includes a motor connected to a magnetically attached removable blade. The blade extends into the chamber when the grinder is assembled. When the lower cap is closed, the blade grinds material placed in the chamber. When the lower cap is opened, the blade functions as a fan to dispense ground material out of the chamber. The grinder also includes a display, an electronic scale, and an accessory cigarette lighter.
