A method for producing reconstituted tobacco includes comminuting the solid components of tobacco to a particle size of about 20-220 μm; mixing the comminuted tobacco product with water, at least one binding agent and at least one material to form an aerosol until a mixture with a liquid content of about 30-50% is obtained; subjecting that mixture to a first lamination to obtain a strip of continuous thickness of about 1-20 mm; subjecting the strip to additional rolling passages to obtain a strip having a substantially constant thickness of approximately 90-280 μm; and drying the strip to bring its liquid content to about 8-15%.

A method is provided for processing at least two starting materials into a final processed product where a predetermined moisture interval is provided for each starting material. The method comprises subdividing each moisture interval into two or more moisture classes and measuring a moisture content for each starting material prior to processing. Each starting material is then assigned to one of the two or more moisture classes and processed depending on the assigned moisture class. A moisture measurement of the final processed product is determined and one or more processing steps are adapted based on the measuring results for the final processed product to achieve a homogeneous moisture distribution in the final processed product.

An apparatus and method for automatically preparing a mixture of particles of two or more substances such as but not limited to raw tobacco and raw medical cannabis flowers in one or more receptacle where the mixture proportion is predefined, is disclosed. The apparatus of the invention can be used for mixing any types of herbal substances. Moreover, the apparatus of the invention can be used for mixing one or more kinds of the same substance, for example mixing two or more kinds of marijuana strains. The apparatus includes one or more compartments for inserting each of the substances separately. In some variations of the present invention the size of at least one of the compartments is smaller for predefined smaller quantities of raw herbal material for example, a single marijuana flower.
