Flour is one of the five staple.
Flour is one of the five staple grains rice, wheat, corn, soybeans and potatoes, and is one of the foodstuffs that billions of people around the world depend on for their survival. Flour particle size (also known as flour coarseness and fineness) is an important physical parameter of flour. 



Flour particle size affects the production process and quality of pasta.
It is found that flour particle size is related to fermentation resistance, large particle size is not easy to ferment, small particle size is easy to ferment; particle size is related to baking characteristics, large particle size has poor baking characteristics, medium fine particle size has better baking characteristics; particle size is related to cookies ductility, large particle size has strong ductility of cookies, and the ductility of cookies decreases with low particle size.

Flour particle size has a greater effect on the noodles.
If the flour particle size is too large, the water absorption will be affected, the noodles will have more breakage, and the luster and brightness will be poor. If the flour particle size is too fine, the water absorption will be greatly increased, which will reduce the surface strength of noodles, and the noodles will become soft and sticky under the action of amylase. Thus, particle size is closely related to the quality and performance of flour.

Why we need laser particle size to measure the particle size of flour?
1. The existing flour industry particle size standards and testing methods - sieving method is a traditional means, it is low cost, simple operation, but its results are greatly affected by human operation, long testing time, can not get the particle size distribution, especially can not get the distribution of 75μm or less, affecting the performance of the flour functional development and the potential characteristics of the It affects the functional development of flour properties and potential characteristics.

2. Measuring flour particle size with laser particle sizer has the advantages of fast testing speed, good repeatability, easy operation, etc. Especially, it can get the particle size distribution of flour in the full range, which can provide a strong technical support for improving the quality of flour, and developing more competitive and new functional flour products.

3. Aoda company provide laser particle size analyzer can accurately measure the particle size distribution of flour in 30 seconds, which not only meets the standard requirement of flour particle size, but also gets the content (particle size distribution) of each particle size section, which plays an important role in the production and testing of functional flour, special flour, and tailored flour, and it is a powerful tool for flour production and application enterprises to improve quality and efficiency, and save energy and reduce consumption.
