Freeze-drying arrangement

Abstract

The present invention relates to a freeze-drying apparatus (1) for drying liquid-containing products (10), comprising a vacuum chamber (11) designed to receive the liquid-containing products (10), wherein a receiving device (12) having at least one receiving plate (13) is provided, the liquid-containing products (10) being able to be placed on top of the at least one receiving plate, and wherein a cooling system (14) having a fluid circuit (15) is provided to cool and / or heat the products (10) by means of a cooling fluid (16) guided in the fluid circuit. According to the invention, at least one fluid tube (17) is disposed on the underside of the receiving plate (13), the fluid tube being part of the fluid circuit (15), and the cooling fluid (16) may flow through the fluid tube to cool and / or heat the receiving plate (13), and thus cool and / or heat the products (10), and wherein at least one sound generator (18) is disposed on the underside of the receiving plate (13), the at least one sound generator being provided for introducing ultrasound into the products (10) during a drying stage, wherein the sound generator (18) is disposed adjacent to the at least one fluid tube (17). The invention relates to a freeze-drying arrangement (1) for drying liquid-containing products (10), comprising a vacuum chamber (11) designed to receive the liquid-containing products (10), wherein a receiving device (12) with at least one receiving plate (13) is provided, onto which the liquid-containing products (10) can be placed on top, and wherein a cooling system (14) with a fluid circuit (15) is set up to cool and / or heat the products (10) by means of the cooling fluid (16) guided in the fluid circuit (15).According to the invention, at least one fluid pipe (17) is arranged on the underside of the receiving plate (13), which is part of the fluid circuit (15) and through which the cooling fluid (16) can flow in order to cool and / or heat the receiving plate (13) and thus the products (10), and it is provided that at least one sound generator (18) is arranged on the underside of the receiving plate (13), which is provided for introducing ultrasound into the products (10) during a drying phase, wherein the sound generator (18) is arranged adjacent to the at least one fluid pipe (17).
