Next, the tobacco material to which potassium carbonate was added was subjected to a heat treatment under conditions of a water concentration of 30 (%) and a temperature of 100 (°C). Then, to the tobacco residue after heat treatment, water is added in an amount 15 times the weight of the tobacco material before heat treatment, and immersed in water for 10 (min), followed by centrifugal dehydrator. dehydrated with The dehydrated tobacco residue was then dried in a dryer.

- sample SA5 an unwashed tobacco residue molded article whose entire surface was coated with polyvinyl alcohol (PVA) was used.
- sample SA6 a molded product of tobacco residue washed with neutral water to a pH of 9.6 was used, the entire surface of which was coated with PVA.
- sample SA7 a tobacco residue molded product washed with an acidic cleaning solution to a pH of 4.1 and coated with PVA on the entire surface was used.
- SA1 to SA7 SA3, SA4 and SA7 correspond to Examples, and SA1, SA2, SA5 and SA6 correspond to Comparative Examples.
- SA1 to SA4 When comparing SA1 to SA4, which are not coated, in Table 1, SA2 to SA4, which have been cleaned, have a smaller amount of carbide formation than SA1, which has not been cleaned.
- SA3 and SA4 in which the pH of the tobacco residue after washing is less than 8.0, produced less char than SA2, in which the pH of the tobacco residue after washing is 9.6.
- SA4 in which the tobacco residue after washing has a lower pH, produces less carbide than SA3.
- SA5 to SA7 that are coated are generally SA1 to SA4 It can be seen that the amount of carbide produced is less than
- the amount of char formed decreased when the pH of the tobacco residue was reduced to less than 8.0 by washing with an acidic cleaning liquid having a pH of 7.0 or less. Further, it has been confirmed experimentally that the amount of char formed can be more effectively reduced by coating the entire surface of the tobacco residue, which has been washed with an acidic cleaning liquid having a pH of 7.0 or less and has a pH of less than 8.0. rice field.
- the load 40 was scorched by manufacturing the compact 61 using tobacco residue washed with an acidic cleaning liquid having a pH of 7.0 or less and having a pH of less than 8.0. Furthermore, by coating the entire surface of the molded body 61 with the coating material 62, the occurrence of scorching on the load 40 can be further suppressed.
