Disclosed is a method for processing heat-not-burn cigarettes, including: cutting flaky reconstituted tobacco leaves in a single direction into a plurality of elongated tobacco shreds; and making the plurality of elongated tobacco shreds stay close to each other by pressing in the width direction of the elongated tobacco shreds and then wrapping the same with tipping paper to form a cylindrical tobacco rod, the plurality of elongated tobacco shreds in the tobacco rods being regularly and orderly arranged. In the present disclosure, by orderly arranging the tobacco shreds, orderly-arranged gaps are formed between the tobacco shreds, which greatly improves the porosity, as compared with disorderly-arranged tobacco shreds, and ensures good air permeability and airflow uniformity inside the cigarettes; and the orderly-arranged tobacco shreds and the orderly-arranged gaps formed therebetween provide approximately straight airflow passages for smoke circulation, which reduces the smoking resistance and the smoke adsorption property of the tobacco shreds, and improves the smoke passing efficiency. |
