Abstract: One aspect of the present invention relates to a method for increasing the temperature of a substance which is initially in an at least partly solidified state in a container, where at least one heat exchanger is arranged in the container. One object is to obtain that the temperature of a substance may be changed relatively fast.

Abstract: The present invention relates to a back-flow preventing valve (1) offering low resistance to fluid flow (AF) through the valve in an open position thereof and yet enabling secure closing of the valve. The reduced resistance to flow is achieved by arranging vanes (3, 3′, 3″) of the valve so that in said open position they are essentially balanced with regard to the force of gravity and do not significantly impede the airflow, neither with regard to the pressure drop caused by the valve nor with regard to an undesirable deflection of said airflow. Leaving said open position the vanes are increasingly urged towards their closed position by the force of gravity. Specifically, this is accomplished by inclining the pivot axes (A) of the vanes (3, 3′, 3″) against the general direction of flow (AF) through the valve (1).
