PROBLEM TO BE SOLVED: To provide a laver baking machine capable of securing the roasting quality of laver with a shortened overall length.SOLUTION: A laver baking machine includes: a conveyor on which laver is placed a heater by which laver is exposed to radiation heat a pair of adiabatic side walls vertically disposed on both sides of the conveyor and the heater an adiabatic upper wall disposed between the pair of adiabatic side walls right above the heater an adiabatic barrier horizontally disposed between the pair of adiabatic side walls in a space between the upper and lower belts of the conveyor an adiabatic bottom wall horizontally disposed between the pair of adiabatic side walls right under the conveyor and adiabatic front and rear walls which have a lower end adjacent to the upper-side belt of the conveyor, with a thickness in the transportation direction of the conveyor. A roasting chamber has a reduced capacity in comparison with a conventional one, having enhanced adiabatic effect.COPYRIGHT: (C)2015,JPO&INPIT【課題】 海苔の焙焼品質を確保しつつ、全長を短縮することができる海苔焼機を提供する。【解決手段】 海苔を上載するコンベアと、海苔に輻射熱を照射するヒーターと、コンベアとヒーターの両側に垂設した一対の断熱側壁と、ヒーターの直上で一対の断熱側壁の間に配設された断熱上壁と、コンベアの上下ベルト間の空間で一対の断熱側壁の間に横設された断熱隔壁と、コンベアの直下で一対の断熱側壁の間に横設された断熱底壁と、下端がコンベア上側ベルトに近接しコンベア搬送方向に厚みを有する断熱前壁及び断熱後壁とを設け、焙焼室の容積を従来よりも減少させかつ断熱効果を高めたことにより課題解決できた。【選択図】 図1
