Bureau of material is due to oil frying temperature is not appropriate, the material temperature is too low, the cake water content is too high; cake thickness is not uniform; cake, the cake is not correct;
Exclusion method: take the appropriate direction of steaming to raise the material temperature to 85 degrees Celsius above the water content of less than 7%. When the cake is concerned, the cake is thick. Properly reduce the press speed.
