Abstract

An apparatus for preparing a layered food product has a station for introducing a first food component into a container and a station for introducing a second food component into the container on top of the first food component. The apparatus also has a unit for metering CO.sub.2 snow onto the first food component and a suction unit for removal of residual CO.sub.2 snow before introduction of the second food component into the container, the metering and removal being effected during passage of the first food component in the container through a tunnel in which air conditions about the container may be controlled.
