An image formation device includes a support, a fluid ejection device, and a first porous element. The support is to support movement of a substrate along a travel path, while the fluid ejection device is located along the travel path to deposit droplets of colorants within a liquid carrier onto the substrate to at least partially form an image on the substrate. A first porous element is located downstream from the fluid ejection device to be in contact against the substrate to remove, via capillary flow, at least a portion of the liquid carrier from the substrate. An ultrasonic element is in contact against the first porous element, at a location separated from a location at which the first porous element engages the substrate, to drive the removed liquid carrier out of the first porous element.

A dryer includes piezoelectric elements powered by oscillatory voltage. The unique piezoelectric elements are placed on the conveyor system or drums moving with the wet material. The oscillating voltage is uniquely connected to the moving piezoelectric elements. The vibration of the piezoelectric elements extracts liquid from the wet material in the form of a cold mist that can be vented, captured, reclaimed, or drained.

A freeze drying plant for drying products containing liquid has a vacuum chamber configured to receive the products. A reception device has at least one reception plate onto which the products can be applied. A cooling system has a fluid circuit configured to cool and/or to heat the products by a cooling fluid conducted in the fluid circuit. The reception plate has at least one closed fluid space that is connected to the fluid circuit and that cooling fluid flows through. At least one sound generator introduces ultrasound into the products during a drying phase, with the sound generator disposed in the fluid space and being able to be flowed around by cooling fluid.
