Abstract: Disclosed is a manual coffee grinder machine for domestic use, of the compact and portable type, having a central body which integrates a hermetically sealed bean reservoir and is joined to a container for the ground powder, which is provided with a quick release clutch with magnets. The grinding unit acts on a horizontal rotation axis, with large-sized flat vertical grinders and an external actuating lever which is located on a side, with respect to the central body, so as to facilitate the introduction of the beans and improve stability during the grinding phase. The lever can be integrated in a retracted way with a snap overturning mechanism. The constructive configuration of the grinder machine optimizes the quality of grinding and the manual actuation, and it also improves the preservation of coffee and offers high efficiency and ease of use.

Abstract: A coffee grinder-loser apparatus has a removable grinding chamber that is extractable with a fast release. Grinding adjustment is independent of access to the grinding chamber. An interface flange is interposed between an adjusting ring nut and a fixed chamber of the grinding chamber. The flange makes an indirect coupling of the ring nut and of an extractable group of components to the fixed structure. A locking system includes levers with a cam tooth mounted externally on the interface flange. The cam tooth hooks a head of tie-rod assemblies with an elastic spring so as to place them in traction and joined to the fixed structure of the grinding chamber.

Abstract: 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.
