Claims
- 1. A method for continuous roasting of food materials comprising the steps of: mixing up and transferring a food material in a powdery, particulate, chipped or shredded form in a horizontally placed, tubular cylinder with open ends under heating with the use of a paddle screw provided with a plurality of blades; wherein said plurality of blades are attached to a shaft of said paddle screw via an elastic member, and wherein said steps of mixing up and transferring the food material in said tubular cylinder includes scraping an inner wall of said tubular cylinder with said plurality of blades.
- 2. A method for continuous roasting of food materials as claimed in claim 1, wherein said food material is supplied quantitatively from the inlet of said tubular cylinder and mixed up and transferred therein in such a state as filling not more than a half of the cross-sectional area of the bore through said tubular cylinder.
- 3. A method for continuous roasting of food materials as claimed in claim 2, wherein said food material is mixed up and transferred with a paddle screw provided with angle adjustable blades.
- 4. A method for continuous roasting of food materials as claimed in claim 1, wherein said food material is mixed up and transferred with a paddle screw provided with angle adjustable blades.
- 5. The method for continuous roasting of food materials in accordance with claim 4, wherein said angle adjustable blades are attached to a shaft of said paddle screw via the elastic member, and wherein said steps of mixing up and transferring the food material in said tubular cylinder includes scraping the inner wall of said tubular cylinder with said angle adjustable blades.
- 6. The method of continuous roasting of food materials as claimed in claim 4, wherein said angle adjustable blades scrape the inner wall of said tubular cylinder.
- 7. A method for continuous roasting of food materials comprising the steps of:continuously supplying a food material in a powdery, particulate, chipped or shredded form from an inlet at one end of a horizontally placed, tubular cylinder; mixing up and transferring said food material in said tubular cylinder with open ends under heating with the use of a paddle screw; and continuously discharging the food material from an outlet at another end of said tubular cylinder; wherein said paddle screw comprises a plurality of blades which are attached to a shaft of said paddle screw via an elastic member, and wherein said step of mixing up and transferring the food material in said tubular cylinder includes scraping an inner wall of said tubular cylinder with said plurality of blades.
- 8. A method for continuous roasting of food materials as claimed in claim 7, wherein said food material is supplied quantitatively from the inlet of said tubular cylinder and mixed up and transferred therein in such a state as filling not more than a half of the cross-sectional area of the bore through said tubular cylinder.
- 9. A method for continuous roasting of food materials as claimed in claim 7, wherein said food material is mixed up and transferred with a paddle screw provided with angle adjustable blades.
- 10. The method for continuous roasting of food materials in accordance with claim 9, wherein said angle adjustable blades are attached to a shaft of said paddle screw via the elastic member, and wherein said steps of mixing up and transferring the food material in said tubular cylinder includes scraping the inner wall of said tubular cylinder with said angle adjustable blades.
- 11. The method of continuous roasting of food materials as claimed in claim 9, wherein said angle adjustable blades scrape the inner wall of said tubular cylinder.
