• a rotating mechanism for rotating the growing chamber,
• a first pipe configured and arranged to introduce at least one of air and another gas into the growing chamber in such a manner that the at least one of air and another gas flow is capable of tracing at least some part of the surface of the body or bodies, and
• a second pipe configured and arranged to remove at least one of air, another gas and washing fluid from the growing chamber,
• wherein the body or bodies are configured to move freely when the growing chamber is rotated, and
• wherein the growing chamber and the body or bodies are further configured to define spaces for air, the spaces arranged between the body and the inner wall of the growing chamber or between the bodies and the inner wall of the growing chamber when food is spread at least partly on surfaces of the body or bodies and the inner wall.
