The invention relates to a device for drying wood, comprising: a container (1) for accommodating the wood (2) and a plate (4, 4′, 4″) forming a wall (3) of the container (1, 1′, 1″, 1″), wherein the plate (4) can be heated and wood (2) at least partially lies against the plate (4).

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.
