A low-temperature processing method of wheat flour and the system device and application thereof

Abstract

The invention discloses a low-temperature wheat flour processing method, a system device adopting the method and application. Wheat is stored in a dry environment of 15-20 DEG C, the wheat is processed by using the wheat processing device, primary screening, stone removal and wheat wetting are performed for 10-12 hours, the wheat wetting temperature is 18-25 DEG C, 6-12 KGy gamma ray irradiation sterilization, secondary roughening, twice breaking, flat-screen screening and cooling are performed, the rotation speed is 38 r / min-40 r / min after the first time of stone-mill grinding, and then wheat flour is produced through three times of flat-screen screening and stone-mill grinding. The method is high in production efficiency and free of additives, a cooler is added to reduce high material temperature caused by a flour mill, meanwhile the rotation speed of a stone mill is improved from 20 r / min to 40 r / min, the powder yield can be up to 87%, it is detected that the moisture content of the produced wheat flour is below 4.5%, the ash content is below 0.8%, the magnetic metal content is below 0.00015%, and gluten quality is up to 28%.

Description

technical field [0001] The invention belongs to the technical field of grain processing, and more specifically, the invention relates to the technical field of a wheat flour processing method. Background technique [0002] With the improvement of people's living standards, people's demand for nutritious, natural and pollution-free food resources is becoming more and more urgent. Wheat flour is the staple food in most parts of northern China, and there are various foods made from wheat flour. The physical and chemical quality indicators of wheat flour mainly include: gluten quality, flour thickness, flour water absorption, ash content, flour color, sedimentation value, falling number and other indicators. [0003] At present, the flour produced by the processing factory has the problems that the moisture content in the flour generally cannot meet the requirements of the national standard, the content of magnetic metals exceeds the standard, there are many additives, residual...

Problems solved by technology

[0003] At present, the flour produced by the processing factory has the problems that the moisture content in the flour generally cannot meet the requirements of the national standard, the content of magnetic metals exceeds the standard, there are many additives, residual harmful substances in the flour, and the high-speed grinding of the wheat flour during the processing process, making the powder Produces high temperature, destroys the quality problems such as the nutrients contained in the grain flour
