Description

  The present invention relates to castella firing tunnel ovens. More specifically, the present invention relates to a castella firing tunnel oven in which a firing process is performed in the process of transporting the castellar dough.

In order to produce castella, it is common practice to mix ingredients such as chicken eggs, sugar, flour etc. mixed with a small amount of water and put the battered dough seeds in a crate and bake in an oven.
For example, if the castellar dough is baked in a deck oven, the castellar dough is warmed at about 50 ° C., and then taken out of the oven to foam.

  Then, the upper surface of the castella is baked at a high temperature in the oven, and baking is performed for about one hour in the oven in a state where the wooden frame is covered with an iron plate. During this time, open the steel plate twice in the oven to degas the crate.

  Therefore, in a three-stage deck oven, only three blocks of castella can be fired simultaneously, so tunnel ovens that can be fired continuously are starting to be used when producing large volumes of castellas. .

As a tunnel oven of this type, for example, the one described in Patent Document 1 is known.
Specifically, as shown in FIG. 9, the heating device 101 is configured to include a heating furnace 102 for generating hot air and a heating duct 104 disposed along the conveyance path of the material to be fired, and The hot air generated by the heating furnace 102 passes through the heating duct 104 and is returned to the heating furnace 102 again.

  With such a configuration, the belt of the transfer conveyor 105 is heated by the heating duct 104 while moving along the transfer path of the baking material of the oven 106.
