Then, the calculation unit 80a divides the total calorific value Σ(Q _{1, i} ‧M _{1, i} ) of the first raw material RM1 by the total _{input amount M 1} of the first raw material RM1 to calculate the storage in the first raw material storage bin _{The average calorific value Q 1} (kcal/kg) of the first raw material RM1 in 71. And, similarly calculate the total calorific value Σ(Q _{2, i} ‧M _{2, i} ) and Σ(Q _{3, i} ‧M _{3, i} ) of the second raw material RM2 and the third raw material RM3 and the average calorific value Q ₂ and Q ₃ .

Finally, the calculation unit 80a calculates the first raw material storage silo 71, the second raw material storage silo 72, and the third raw material according to the designated heating value Q _d and the designated weight M _{d (for example, the designated heating value and the designated weight of the customer order)} The storage bin 73 respectively stores the first raw material RM1, the second raw material RM2, and the third raw material RM3 in the feed amounts M _O,1 , M _O,2 and M _{O,3 respectively} .
