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.

A method and an apparatus are described to grind a product, for example a product in grain form, which provide to compare a value of estimated weight (pk*) with a predefined quantity (pTARGET) that has to be delivered in a delivery cycle, and that has been set by the user. The value of estimated weight (pk*) is calculated by adding a weight (pk) detected at successive instants (tk) of the delivery cycle with a suitable correction factor (C).

A brewing device may have several different configurations to make various beverages. Under computer control, the device may be able to sequence various ingredients using direct or recirculating percolation for immediate consumption, such as coffee and tea, or for fermenting for later consumption, such as beer, kombutcha, or other consumable products. The device may be capable of a sequenced percolation, such as coffee infusion of a first type of coffee, then a second type of coffee, followed by vanilla, and followed by spices. The device may be capable of sequential, cascading, or parallel percolation directly or using recirculating paths. Ingredients may be pre-packaged or may be placed into various removable and cleanable containers. The device may further be capable of infusion by steeping ingredients in a dispensing device.
