A apparatus (100) for roasting coffee beans is disclosed comprising a compartment (110) for holding coffee beans (10); a roasting element (140) for roasting the coffee beans in said compartment; and a processor (130) comprising a control unit (134) for controlling the roasting element. Wherein, the processor (130) is adapted to determine a weight loss rate of the coffee beans, and the control unit (134) is adapted to control the roasting element as a function of the determined weight loss rate. A coffee machine including such an apparatus and a method for roasting coffee beans are also disclosed.

The electrode drying device includes a transfer unit that transfers an electrode sheet having an electrode slurry coated onto the current collector, and a drying chamber including an inflow port where the electrode sheet transferred by the transfer unit enters, wherein an interrupting member for adjusting the flow amount or flow velocity of outside air flowing in a drying chamber is formed at the inflow port, and a height of a central part of the interrupting member is different from a height of a peripheral part of the interrupting member.

A method for reducing moisture of a material includes applying microwave radiation combined with RF to the material to heat and evacuate moisture from the material during a heating cycle and optionally alternating heating cycles with drying/cooling cycles. In particular, a method is disclosed to reduce a moisture content level of a material that comprises introducing the material or plant vertically into a drying enclosure using a vertical feed mechanism. The method further includes irradiating a portion of the material or plant with microwave to heat and vaporize moisture within the material or plant during a heating cycle; combining or alternating the microwave with RF heating for a time interval during the heating cycle to reduce the moisture content level of the material or plant; and alternating the heating cycle with a cooling cycle. In certain aspects or embodiments, the system comprises at least an enclosure, a vertical track mechanism, a microwave delivery device, a radio-frequency emitter and power supply.

Systems and methods for evenly heating a drum dryer of a print system. In one embodiment, the dryer is configured to rotate about an axis oriented in a lateral direction, to receive a radiant energy source disposed inside the drum that extends between each lateral end of the drum in the lateral direction, and to receive a reflective assembly inside the drum that includes an inner portion and an outer portion. The inner portion surrounds the radiant energy source and removably attaches the reflective assembly to a lateral end of the drum. The outer portion extends from the inner portion in a radial direction of the drum that is perpendicular to the lateral direction. The outer portion includes a reflective surface that reflects radiant energy from the lateral end to the central portion of the drum in contact with the web.

The apparatus (100) comprises several stations for treating fabric (10). For example, a cleaning station (20) is provided that is arranged to remove loose debris from the fabric and move the fabric in a continuous motion through the cleaning station. A treatment station (40) is then arranged to receive the fabric from the cleaning station and to transfer treatment fluid to the fabric in a treatment zone. Finally, a drying station (50) is arranged to receive the fabric from the treatment station and to dry the fabric in a drying zone. Advantageously, the treatment station is arranged to transfer the treatment fluid by spraying the treatment fluid under pressure onto a side of the fabric.
