In this paper, the main steeping technology of wheat is studied. According to the contaminated degree of grains formaldehyde added is between 0.05-0.1‰. When the steeping degree reaches about 39%, it is transferred into Saladin. The final steeping degree is 42-45%, the highest not over 46%. Steeping with dry rests is used. During the dry rests CO2 is removed. Under given steeping degree steeping time is reduced with raising of steeping temperature.
