The invention relates to a method for operating a heat exchanger (1), in which a first operating mode is carried out in first time periods, and a second operating mode is carried out in second time periods that alternate with the first time periods; in the first operating mode a first fluid flow (A) is formed at a first temperature level, is fed into the heat exchanger (1) in a first region (2) at the first temperature level, and is partially or completely cooled in the heat exchanger (1); in the first operating mode a second fluid flow (B) is formed at a second temperature level, is fed into the heat exchanger (1) in a second region (3) at the second temperature level, and is partially or completely heated in the heat exchanger (1); and in the second operating mode the feeding of the first fluid flow (A) and of the second fluid flow (B) into the heat exchanger (1) is partially or completely halted. In the second time period the second region (12) is cooled by using cooling fluid that is conducted through passages in or on the heat exchanger (1) in the second region (12) but not in the first region (11) which comprises the terminal 30% at the warm end of the heat exchanger (1). A corresponding arrangement (10) and equipment (100) with such an arrangement (10) are also covered by the present invention.

The invention discloses a heat transfer roller with a graphite interlayer and a heat transfer method thereof. The heat transfer roller includes: an outer cylinder 1 , an inner cylinder 2 , a graphite interlayer 3 , and an infrared heating tube 4 . The graphite interlayer 3 is sandwiched between the inner cylinder 2 and the outer cylinder 1 of the heat transfer roller. Both the inner cylinder body 2 and the outer cylinder body 1 are metal layers. The invention utilizes the very high thermal conductivity of the graphite plane to improve the temperature transfer efficiency along the heat transfer roller surface, and an intermediate layer of graphite material is arranged in the heat transfer roller device to greatly improve the temperature uniformity of the heat transfer roller.

A method for continuous microwave expansion of cut tobacco comprises the following steps: impregnating the cut tobacco in an expanding agent; recycling the expanding agent in an impregnating device after impregnation; carrying out microwave expansion on the impregnated cut tobacco by a microwave dryer to obtain the expanded cut tobacco. The expanded cut tobacco comprises one or more than two components of ethanol with 4-12 carbon atoms, ketone with 4-12 carbon atoms, halogenether with 2-12 carbon atoms, alkane with 3-12 carbon atoms or alkane with 3-12 carbon atoms substituted by 2 halogen atoms. The filling value of the expanded cut tobacco reaches above 7.5, the cutting ratio is above 90%, the moisture content after expansion is 12-13%, the expansion of the cut tobacco is even without water damaged cut tobacco; the whole set of devices has low energy consumption and high automation, and continuous closed mass production can be carried out.
