Abstract: Hopper (10) for food products in the form of grains, beans, powder or suchlike, comprising a container (11) for the food products having an introduction aperture (13) and an exit aperture (12), attachment means (19) configured to selectively and removably attach the container (11) to a machine (200) for processing the food products, a pneumatic connection member (20) configured to allow the extraction of air from the container (11) and closing means (15, 17) configured to selectively and hermetically seal the container (11).

Abstract: A hopper for feeding beans contains a container for the beans, a closing bottom disposed rotatable with respect to the container in order to selectively open and close an outlet aperture for the beans, and feed means which can be selectively driven to feed the beans toward the outlet aperture. Also provided are an apparatus and a method for grinding the beans, a machine, and the corresponding method for preparing a beverage.

Abstract: Grinding apparatus including a hopper provided with feed means, the hopper being configured to contain and feed the beans, a grinding device configured to grind the beans, and weighing means for weighing the beans.

Abstract: The instant electric heater for a fluid comprises an axial metal tube, electric resistive means positioned on an outer surface of the metal tube, an inlet manifold body and an outlet manifold body positioned at the ends of the metal tube, a screw positioned along an internal axial cavity of the metal tube and having a thread delimiting, with an inner surface of the metal tube, a helical channel for conveying the fluid from the inlet manifold body to the outlet manifold body, temperature sensor means for sensing the temperature of the fluid, and an outer casing for the protection of the metal tube, the electric resistive means comprising at least a first electric heating element and a second electric heating element that can be independently powered.

Abstract: Grinding apparatus for grinding a substance in the form of beans into powder, including at least one hopper removably connected to a support structure, a grinding device configured to grind the beans, and weighing means for selectively weighing the hopper and the beans present therein.

Abstract: The device for processing loose coffee comprises an electronic controller, a support, at least one first filter holder that is engageable with the support, at least one first filter, wherein the first filter holder comprises a cup where the first filter is housed, wherein the cup has at least two wings engaging the first filter holder with the support, means for the automatic recognition of the first filter being provided positioned in the first filter holder engaged with the support, the recognition means being connected to the electronic controller to program an operation with at least one parameter depending on the first recognized filter.

Abstract: The device for preparing a dose of ground coffee powder ready for infusion comprises a cup provided with a gripping handle and housing a filter containing said dose of ground coffee powder, a coupling support in which the cup is coupled separably, and a pressing piston that is engageable in the filter for pressing the dose of ground coffee powder, the pressing piston having anti-detachment means configured to prevent the detachment of the pressed dose of ground coffee powder from the walls of the filter when the pressing piston disengages the filter.

Abstract: An electric radiant hotplate includes a base of electrically insulating material and a peripheral crown extending along the outer rim of the base and projecting upwards. A strip of resistive material is inserted in the base and is formed by a sequence of planar lengths and curved lengths connected to respective planar appendices that are inserted in the insulating base. The appendices can be connected to the planar lengths by respective peduncles applied on to the same side edge of the flat strip of resistive material. The appendices can also be either coplanar or not coplanar to the planar lengths and include a first portion connected to the respective planar length of the strip, and at least a second planar portion that is not coplanar with the first portion and is joined to the first portion via a rectilinear border, the first portions being applied on a same side edge of the flat strip of resistive material.

Abstract: Electric radiant hotplate, suitable also for use in cooking tops, comprising: a base of electrically insulating material, a peripheral crown extending along the outer rim of said base and projecting upwards, at least a strip or resistive material that is inserted in said base dand is formed by a sequence of planar lengths and curved lengths are connected to respective planar appendices that are inserted in the insulating base. In one embodiment, said appendices are connected to the planar lengths by means of respective peduncles applied on to the same side edge of the flat strip of resistive material.
