Description

Technical Field

[0001] The utility model belongs to the field of equipment for modification experiments, and in particular relates to a modification device for grain experiments. Background Art

[0002] Coarse grains are rich in nutrients and dietary fiber, which can promote intestinal peristalsis and balance the nutrition needed by the human body. However, many people find it difficult to accept the rough taste of coarse grains. Therefore, a production process using screw extruders to modify coarse grains has appeared on the market to improve the taste of coarse grains and make them more acceptable to the public. The degree of modification of coarse grains is often achieved by controlling the temperature, humidity and pressure in the screw extruder. The control of temperature and humidity is relatively simple, while the pressure is affected by the gap between the screw and the barrel wall. In the actual production process, it is difficult to determine the gap between the screw and the barrel wall suitable for different coarse grain modifications, which can easily cause the degree of modification of the coarse grains to be too large or too small, and the taste of the coarse grains cannot achieve the expected effect.
