More specifically, the present invention will be described in detail. An unfermented yeast donut dough stored in a freezer is heated to a temperature of 40 to 60% and a temperature of 15 to 22 ° C. at a temperature of 14 ° C. at the center of the dough. Thaw and raise the temperature until the temperature reaches or more than ℃ (hereinafter, this temperature increase is referred to as a pre-stage temperature increase). Next, the environment temperature is increased at a rate of 1 ° C. or more per minute under an environment of a humidity of 50 to 70%. This temperature rise is caused when the environmental temperature is 35 ~
Continue until the temperature reaches 40 ° C. (hereinafter, this temperature rise is referred to as a post-stage temperature rise). When the environmental temperature reaches 35 to 40 ° C., the dough temperature, particularly the temperature at the center of the dough, is several degrees lower than this. At the stage where the post-stage temperature rise is completed,
The environmental conditions are kept as they are, that is, the humidity is 50 to 70% and the temperature is 35 to 40 ° C. While maintaining this environmental condition, the temperature of the dough becomes substantially the same as the environmental temperature, and fermentation proceeds during this time. The continuation of the fermentation under environmental conditions is 5
~ 30 minutes, but ends when the donut dough is in a suitable fermented state. The time to the appropriate fermentation state varies depending on the size, shape, temperature rise history, etc. of the dough, so for each type of donut to be produced, determine the optimal time in advance, and in the case of production of the same type, Thereafter, that time may be adopted.

Next, the environment is maintained as it is until the temperature of the central portion of the dough becomes 14 ° C. or more. That is, humidity 40-60
%, And the temperature is kept at 15 to 22 ° C. (hereinafter, the temperature rise up to this point is referred to as a pre-stage temperature rise). Then, humidity 50-70%
The environment temperature is raised at a rate of 1 ° C. or more per minute until the temperature of the environment becomes 35 to 40 ° C., and the environment is left as it is, that is, the temperature is 35 to 40 ° C. and the humidity is 50 ° C.
The dough is fermented at 7070% (hereinafter, this temperature rise is referred to as a subsequent temperature rise). Continuation of fermentation in this environment is exactly the same as in the case of the above-mentioned invention. That is, the optimum value is determined in advance for each type of yeast donut to be manufactured, and the time is used thereafter. In the above two methods, it is desirable to use a dough conditioner in which predetermined environmental conditions of the present invention are set in a program.

In the above method, if the environmental temperature is 15 ° C. or less at the stage of the first temperature rise, the fried product has a small volume, has no surface, and does not become a good product. Similarly, if the ambient temperature is 22 ° C. or higher in the former temperature rise stage, the temperature difference between the surface portion and the central portion of the dough becomes large, and uneven thawing and fermentation are performed.
This causes large blisters on the surface of the fried product.

If the humidity is less than 40% when the temperature of the former stage is raised, the moisture on the surface of the dough sublimates or evaporates, and the skin of the fried product becomes too hard. On the other hand, if the humidity is 60% or more, the dough is thawed and dew condensation occurs on the surface of the dough during the temperature rise, and the surface of the dough becomes excessive in moisture. For this reason, the fabric tends to bite into the wire mesh at the time of frying, and a mesh pattern called a screen mark is too strong. In addition, the amount of oil absorption during frying increases, the product has a bad texture,
Oil consumption also increases. The temperature rise rate of the subsequent temperature rise is 1.
If the temperature is lower than 0 ° C./min, the fried product has a small volume, takes too much time and may lose moisture, resulting in a poor internal phase. The texture of the product becomes hard, and aging is fast, which is not preferable.
