Abstract
The invention relates to a method for producing a sheet of a material containing alkaloids, the method comprising: • Mixing (105) a material containing alkaloids with water to form a slurry; • Forming (108) a sheet from the slurry; • Compressing (109) the sheet between a first pair of rollers, wherein at the beginning of the step of compressing the sheet, a water content of the sheet is comprised between about 50 percent and about 80 percent of the total weight of the sheet; and • Further compressing (110) the sheet compressed by the first pair of rollers between a second pair of rollers. The invention further relates to an apparatus (200) for producing a sheet of a material containing alkaloids.
Claims15
A method for producing a sheet of a material containing alkaloids, the method comprising:
- mixing a material containing alkaloids with water to form a slurry;
- forming a sheet from the slurry;
- compressing the sheet between a first pair of rollers, wherein at the beginning of the step of compressing the sheet, a water content of the sheet is comprised between about 50 percent and about 80 percent of the total weight of the sheet;
- and
- further compressing the sheet compressed by the first pair of rollers between a second pair of rollers, to obtain a desired thickness of the sheet of material containing alkaloids.
An apparatus for producing a sheet of a material containing alkaloids, the apparatus comprising:
- a mixer to mix a material containing alkaloids with water to form a slurry;
- a sheet-forming device to shape a slurry's portion into a sheet;
- and
- a dryer, said dryer comprising:
- a first pair of rollers forming a first gap therebetween wherein the sheet can be inserted;
- and
- a second pair of rollers forming a second gap therebetween wherein the sheet can be inserted, the second pair of rollers being positioned downstream the first pair of roller in the direction of movement of the sheet;
- the first pair of rollers or the second pair of rollers being heated by hot fluid.
