Grain Sieves

What is a Grain Sieves?

Grain sieves is an instrument for grain and grain screening, which can be used for the inspection and analysis of grain weighing up to 2kg in the range of 20µm-63mm. Through sieving, grain can be separated from impurities such as chaff, so as to achieve the purpose of grain screening and analysis of grain quality grade.

Types of Grain Sieves

Grain Sieves is a testing instrument for testing the impurity content in grain and oil samples and the bran powder content in rice to determine its quality grade. According to its application, it can be divided into the following two types:

1. Deworming sieve: Standard grain sieve is a special instrument for testing the degree of pest infestation in grain and oil samples, and measuring the density and level of pests.

2. Grain selection screen: an inspection instrument for inspecting the quality of wheat, corn and other grains and determining their quality grades.

Grain Sieves Advantages

The grain sieve can quickly remove the impurities in the grain and screen and classify the grain particles.

The grain sieve has 1-6 layers, which can screen the grain into 2-7 different specifications.

Made of 304 stainless steel, one-piece punching, clean and hygienic, easy to clean.

The sieving range is 20µm-125mm, which can detect the particle size content of samples weighing up to 2kg.

Grain Sieves Principle

When Grain sieves sieve grains, the electric machinery rotates forward and reverse to separate the grains. According to the width, thickness or shape of the grains, the grains are selected to pass through different sieve holes, so as to achieve the purpose of grain screening.

Grain sieves are separated according to the width, thickness or shape of seeds and grains. According to the characteristics of grains, they can be divided into three types:

The first is to separate according to the different shapes of grains: use triangular meshes.

The second one is to separate according to the thickness of the grain: the rectangular screen is used, which is separated according to the thickness of the material.

The third type of separation is based on different grain widths (common): circular sieve holes are used, which are mostly used in the separation and screening of seeds and grains.

Grain sieves Instructions for Use

1. Pay attention to the order of the sieve layers, and place them on top of each other to ensure that the sieve grids are vertical and not inclined.

2. During operation and use, handle with care and do not collide with force. One side of the grain sieve will be deformed and damaged, which will affect the quality of inspection.

3. Grain sieve should not be in contact with chemical substances such as acid, alkali, grease, etc. After use, rinse with water and dry

4. Once the sieve is found damaged, it should be replaced in time to ensure the accuracy of the test results.
