Seating Machine For Stone Ground Flour

Seating machine for stone ground flour is a device used to screen flour in the process of stone ground flour production. Its main function is to finely screen the flour after stone grinding, remove coarse particles, bran, impurities, and separate flour of different particle sizes to ensure the fineness and quality of the finished flour. It is an important part of the stone ground flour production line, which aims to grade the flour after stone grinding according to particle size through screening, and remove bran and other impurities, so as to obtain flour products of different fineness.

Scope of application

Applicable to grains such as wheat, corn, sorghum, buckwheat, and soybeans;

Can be used in farms, flour mills, organic food processing companies, and small food factories;

Can also be used for low-temperature fine processing occasions such as crushing Chinese medicinal materials and grinding tea powder.

The role and importance of seating machine for stone ground flour

 

The characteristics of stone mill grinding are low temperature and low speed, which can retain the natural nutrients and original flavor of wheat. However, the flour ground by stone mill usually contains particles of different sizes and a certain amount of bran. In order to meet the market demand for flour for different purposes and improve the quality and taste of flour, the screening process is essential. The main functions of seating machine for stone ground flour include:

①Grading: Separate the ground mixture according to different sieve apertures to obtain flour of different coarseness and fineness, such as whole wheat flour, refined flour of different grades, etc.

②Removal of impurities: Seating machine for stone ground flour can effectively remove bran, germ fragments mixed in the flour, and other impurities that may be generated during the grinding process.

③ Improve the quality of stone-ground flour: Through precise screening, bran, impurities, stones, etc. in stone-ground flour can be removed, making the flour purer and better tasting, improving the quality and grade of flour, and meeting the needs of different users.

Working principle

Most seating machines for stone ground flour use a vibration motor to drive the screen, using vibration to make the flour particles jump on the screen surface, fine powder falls into the lower layer through the screen holes, and coarse powder moves along the screen surface to the outlet. The equipment is usually equipped with multiple layers of screens (such as 30 mesh, 60 mesh, 80 mesh, etc.), which can gradually screen out flour of different fineness, and the coarse particles can be returned to the stone mill for re-grinding.

Recommended mesh number of seating machine for stone ground flour

The stone-ground flour screening machine is specially designed for the fine processing of traditional stone-ground flour, and particle classification is achieved through multiple layers of vibrating screens (30 mesh, 60 mesh, 80 mesh, 100 mesh, etc.).

30-40 mesh screen retains bran and produces whole wheat flour; 60-80 mesh screens out general flour, suitable for steamed bread and noodles; 100-120 mesh screens can produce fine flour, which is used for cakes, dumpling wrappers, etc.

What are the advantages of Seating machine for stone ground flour?

 

① Solve the problem of uneven particle size of stone ground flour: The screening machine is usually equipped with multiple layers of screens with different mesh sizes. When stone ground flour is screened, starting from the upper screen, larger particles are intercepted by the first layer of screen. As the flour moves on the screen, it gradually passes through screens with different mesh sizes and is screened into products of different particle size grades, thereby ensuring the uniformity of the size of flour particles.

② Deal with the problem of difficult impurity removal: According to the type and size of impurities that may exist in stone ground flour, choose the appropriate screen material and structure. For example, for impurities such as fine sand particles, a stainless steel screen with a small aperture and a smooth surface can be used. Seating machine for stone ground flour can effectively intercept impurities while ensuring the normal passage of flour.

Application of seating machine for stone ground flour

 

The screening machine plays a key role in particle classification, impurity removal, quality control and bran separation in stone ground flour processing. Its application scenarios cover many fields such as traditional flour mills, high-end baking, handmade pasta, healthy food, organic food and catering supply chain. Through precise screening, the screening machine not only improves the quality and safety of stone ground flour, but also meets diverse market needs. In a typical stone ground flour production line, the screening machine is usually located after the stone mill. After pre-treatment such as cleaning and stone removal, the wheat enters the stone mill for grinding, and the ground material immediately enters the screening machine for processing. Depending on the production process and the type of flour required, one or more levels of screening may be set.

Effects in practical applications

In practical applications, the screening efficiency of stone ground flour can be significantly improved after using seating machine for stone ground flour. For example:

The impurity removal rate can reach more than 95%;

The screening rate is increased by 20%~30%;

The finished product fineness is controlled within the specified range (such as 80~120 mesh);

The screen blockage rate is reduced and the maintenance cost is reduced.

 

Seating machine for stone ground flour is a key equipment in the stone ground flour production line. Its main function is to grade the flour after stone grinding, remove bran, germ and other impurities, so as to obtain flour products of different fineness and grades. This equipment is generally used in flour mills, grain processing plants and other places to improve the purity and quality of flour. Choosing a suitable seating machine for stone ground flour requires comprehensive consideration of factors such as raw grain characteristics, expected flour yield and fineness. Reasonable screening process and high-performance screening equipment are important guarantees for the production of high-quality stone ground flour.
