A device for pastillating a flowable product, in particular a melt. The device has a revolving belt and a drop former, and the drop former deposits product drops on an upper run of the belt. The product drops, in the course of transportation on the upper run of the belt, solidify to form pastilles, and an arrangement for wetting the belt with a liquid release agent is provided upstream of that region in which the product drops are deposited on the belt. The release agent prevents or reduces the adhesion of the product drops to the belt, and a proportional metering pump is provided for continuously mixing the release agent from at least two liquid components during the operation of the device.

A device for spherification of a liquid includes a first device for storing a first liquid; and a spherification tank for storing a second liquid, arranged so that the second liquid defines a level of the second liquid in the spherification tank. A device meters the first liquid coming from the first tank into the spherification tank. An extraction device extracts spheres generated in the spherification tank as a result of the metering. The extraction device includes a worm screw located in the spherification tank, the worm screw being arranged at an angle to the level, and a motor for rotating the worm screw.
