1. Principle
According to the principle that soft and hard wheat have different resistance to mechanical crushing, when crushing, hard wheat It is not easy to turn into powder, while soft wheat is easy to turn into powder. Crush the sample under specified conditions. The ratio of the sample mass on the sieve to the total mass of the sample determines the hard wheat hardness index of the wheat. The hard wheat hardness index tester is driven by a motor and is installed outside the rotor. The surface grinding knife, the grinding knife and the outer cutter disc produce shearing and impact crushing effects on the sample, causing the sample to be crushed. 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 grains with different hardness passing through the screen is different. The hardness of wheat is characterized by the percentage value of the mass of powder grains retained on the screen to the mass of the test wheat sample, which is referred to as "hardness". The greater the hardness index, the higher the hardness of the wheat, and vice versa.
2. Instrument composition:
The good performance of the wheat hardness index tester ensures the repeatability and reproducibility of the experimental results. The wheat hardness index tester consists of a host computer, a weighing system and a data processing system.
