A method of processing coffee grounds. The method includes drying coffee grounds to at least a predetermined dryness by using a rotatory drier to heat and agitate the grounds while measuring the dryness of the drying coffee. After the coffee grounds have been dried, they are mixed with supercritical CO.sub.2 to separate liquid components of the coffee grounds from solid components. This provides a simple, safe way of extracting coffee oil and producing coffee flour.

A plant for the treatment of vegetable products includes a chamber having walls arranged to delimit an internal environment, which, during the operation of the plant, is closed and isolated with respect to the external environment, the products to be treated being intended to be positioned within such chamber; a lighting apparatus positioned within the chamber and configured to emit infrared radiation on the products to be treated; a ventilation apparatus to circulate air inside the chamber; and a dehumidification apparatus configured to control humidity conditions inside the chamber.

The present invention relates to an apparatus for roasting green beans. The apparatus for roasting green beans according to an embodiment of the present invention comprises: a roasting kettle in which a roasting portion responsible for roasting green beans is formed; a heating member for heating the roasting kettle during roasting, the heating member being embedded in a heating hole formed in the roasting kettle and integrated with the roasting kettle; and a stirring device which is rotatably mounted inside the roasting kettle and stirs green beans during roasting. By providing heating to the roasting kettle during green bean roasting, the heating member embedded in the heating hole formed in the roasting kettle therefore enables more efficient roasting, resulting in a great decrease in the roasting time of green beans.

The invention concerns an apparatus (10) for roasting coffee beans comprising : - a roasting chamber (1), - an air driver (8) configured to drive air inside the roasting chamber through the bottom opening of said chamber, - a heater (9) configured to heat air driven inside the roasting chamber, - a chaff collector (3) connected to the roasting chamber through a first channel (31), - at least one beans collector (4) for fully roasted beans connected to the roasting chamber through at least one second channel (41), wherein said apparatus comprises a distributing device (5) configured to open either the first channel to the chaff collector (3) only or to the at least one second channel to the at least one beans collector only.

Disclosed is a coffee bean roaster. The coffee bean roaster includes a roasting unit, a sensor arrangement, and a control unit. The roasting unit has a drum with a transparent and removable front wall. The roasting unit further has a hot air supply and a rear wall heater to heat a rear wall of the drum. The sensor arrangement includes a roasting bean temperature sensor. The control unit is configured to receive a control input signal as a function of time, wherein the control input signal includes the roasting bean temperature signal and the roasting bean color signal, and is further configured to automatically generate a control output signal as a function of time in dependence of the control input signal thereby controlling operation of the drum heater and the drum rotor drive to roast the coffee beans inside the drum according to a pre-determined selected roasting profile, wherein the selected roasting profile includes a desired roasting bean temperature as a function of time, a target roasting bean temperature and a target roasting bean color, wherein the control unit is configured to determine if an end-of-roasting-condition is met, wherein the end-of roasting condition includes the coffee beans inside the drum having the target roasting bean temperature.

A method for preparing a pumpable batch composition of stone fruit and/or nut fruit seeds, in particular nuts, almonds or nut and almond mixtures, with the following steps: Breaking open of the already pitted or stoned stone-fruit or nut-fruit seeds first takes place by pre-crushing. A hot air and/or vacuum exposure of the composition arising from the pre-crushing then takes place for the purpose of breaking open its cells. This is followed by a usually single-stage, optionally also multi-stage, further grinding of the composition arising from the pre-crushing and the hot air or vacuum exposure to form a pumpable batch composition.

A method for obtaining pure drinking water from dewatered biological products is described. The process is carried out in a hermetic dewatering chamber isolated from the ambient atmosphere and in parallel with a process during which dried products are placed on drying trays. All the process parameters, such as temperature, humidity, and appropriate pressure inside the chamber, are controlled. The vapor generated during the product dewatering process, released from the products, is continuously removed from the dewatering chamber through the upper opening, exits through the outflow channel, and enters through the condenser. The process of obtaining clean drinking water is carried out outside the chamber and is conducted in several stages: vapor passes through disinfectant grids, vapor flows to a condenser cooled with ice water, and the vapor condenses on densely arranged lamellas. The condensate is then pumped to a discharge tub.

The present disclosure relates to a roasting apparatus and a method of controlling the roasting apparatus, and more particularly, to a roasting apparatus for roasting objects while stirring the objects in a roasting chamber, and a method of controlling the roasting apparatus. An roasting apparatus for heating objects according to the present disclosure includes a roasting chamber part which includes: a cylindrical roasting chamber that extends in a vertical direction and has an internal space in which the objects are stirred; and a rotary stirring part that rotates to stir the objects received in the roasting chamber and rotates about a stirring axis defined in the vertical direction. The roasting apparatus further includes heat source parts which supply heat to the roasting chamber part.
