Seed treater manufacturers take you to understand the Seed treatment

Seed treater manufacturers tell you that seed treatment is a cost-effective method of plant pest control. Seed treater manufacturers tell you that they use biological, physical, and chemical factors and technologies to protect seeds and crops, control pests and diseases, ensure average crop growth, and achieve high quality and high yield.

Seed treater manufacturers take you to understand seed processing

Seed treater manufacturers tell you that seed processing: also called seed mechanical processing, refers to mechanized operations such as seed threshing, selection, drying, selection grading, coating, and packaging. Seed treater manufacturers tell you that the development of the seed processing industry is a sign of the modernization of seed production.

Structure and working principle of Seed destoner

Before explaining, we must first understand the basic principle of Seed destoner. This machine is suitable for a variety of grain seeds after removing large and small impurities, such as wheat, beans, rice, sorghum, etc. Seed destoner can take advantage of the difference in specific gravity and use wind blowing, sieving, and other treatment methods to separate grain crops from large and small solid impurities. These are the general principles of how a destoner works.

Seed destoner manufacturers take you to understand the role of destoner and its characteristics

Seed destoner manufacturers tell you that destoner is indispensable equipment in wheat processing, used to remove stones and other heavy impurities in wheat. Seed destoner manufacturers tell you that there are mainly two types of destoners produced in China, one is a single-layer destoner with a specific gravity destoner, and the other has a grading function (another layer of grading screen) Gravity Grading Destoner. With the continuous development of stone removal equipment technology and application, because of the advantages and good working results of the latter.

How Gravity destoner works

Gravity destoner is mainly based on the different characteristics of the specific gravity and suspension speed of sand and rice, using a slanted screen surface with certain movement characteristics and the wind force passing through the fish scale holes on the screen surface to separate the grains and stones (the suction-type Gravity destoner also requires a larger air volume).

Seed destoner manufacturers take you to understand how specific gravity destoner works

Seed destoner manufacturers tell you that the specific gravity destoner uses vibration motion, adjusts the airflow, and adjusts the inclination of the screen surface to separate grain and gravel. Grain is a granular body composed of particles with different particle sizes and specific gravity. When subjected to vibration or moving in a certain state, various particles will be divided into different levels according to their specific gravity, particle size, shape, and surface state.

How a Gravity Destoner Works

First, the material enters the Gravity Destoner from the upper feeding port, and before reaching the first stage of the upper screen, it is set by adjusting the screed plate adjustment plate of the feeding box. The material is automatically and evenly distributed on the top screen. The upper screen in the Gravity Destoner automatically generates the material according to the gravity of the material through the combined action of the reciprocating vibration and the upward airflow.

Kjeldahl Nitrogen Analyzer manufacturers take you to understand the issues to be aware of when using the Kjeldahl method

Kjeldahl Nitrogen Analyzer manufacturers tell you that from the principle of Kjeldahl nitrogen determination: Kjeldahl nitrogen determination method is to convert nitrogen-containing organic matter into inorganic nitrogen ammonium sulfate for detection, in order to obtain the measured value of nitrogen content multiplied by a certain coefficient of the protein content.
