Wheat hardness tester, hardness tester, wheat tester Zhengzhou Zhongzhuliang Instrument Equipment Co., Ltd.
Model
Principle
According to the principle that soft and hard wheat have different resistance to mechanical crushing, in When crushing, hard wheat is not easy to turn into powder, while soft wheat is easy to turn into powder. When crushing the sample under specified conditions, the ratio of the sample mass on the sieve to the total sample mass determines the hardness of the wheat.
The wheat hardness index tester uses a motor to drive a grinding knife installed on the outer surface of the rotor. The grinding knife and the outer cutter disc produce shearing and impact crushing effects on the sample to crush the sample. At the same time, the high-speed rotating rotor blades generate a centrifugal airflow field in the crushing chamber. The crushed powder particles enter the hopper through the screen under the centrifugal impact of the airflow field with the rotor and itself. During a certain crushing time, the quality of wheat particles with different hardness passing through the screen is different. The hardness of wheat is characterized by the percentage of the mass of powder particles remaining on the screen to the mass of the test wheat sample, referred to as
. The greater the hardness index, the higher the hardness of the wheat, and vice versa. Instrument composition
The good performance of the wheat hardness index tester ensures the repeatability and reproducibility of experimental results. The wheat hardness index tester consists of a host computer, a weighing system and a data processing system.
