Disadvantage of conventional method1. Baking method
Dough is put into large case with several kg and burnt. Therefore:
- Handling and storage is troublesome due to large case.
- Not suitable for users requires all white bread crumb because the crust is coloured. Peeling crust takes a long time and labour and retention is not good.
- It takes a long time for cooling or aging because a large volume of bread is produced.
- Foreign materials may enter.
- Cost for maintaining cases or for regular replacement is increased.
2. Electrode method
Larger case is used and heat is added by electrode plates. Therefore:
- Handling is more troublesome.
- Foreign materials may enter.
- It takes longer time for cooling or aging because a large volume of bread is produced.
- A number of bacteria are still alive even after being treated by the electrode method. Insufficient heating results in some parts due to its large volume.
