Vibro Sifter Used in Flour Mills

There are three common types of vibrating sifter used for sieving flour: direct discharge sifter, linear vibro sifter and circular vibro sifter. The three types of flour shakers are suitable for different flour application scenarios. The three common flour shakers are used in What kind of flour sieving scene? Let's see the decomposition below.

1. Direct discharge sifter is used for rough removal of flour

In-line flour shaker

In the process of flour preparation, the flour formed by grinding will be mixed with wheat bran; in addition, when the finished flour is used for instant noodle processing, biscuit processing, and noodle processing, the flour will be mixed with large quantities of quality certificates, packaging threads, etc. accidentally dropped into the flour. Particle impurities, usually the content of impurities is about 5%, in order to quickly remove these impurities, usually use direct discharge sifter as a flour vibrating screen, at this time the general sieve mesh requirement is 18 mesh.

Direct discharge sifter uses the excitation force provided by the vibrating motors installed on both sides of the sieve to drive the flour to move up and down on the sieve surface, and adopts a direct discharge method. The sifted flour is directly discharged through the sieve at the bottom. The material outlet is discharged, which is in line with the requirements of rough removal of impurities and high output of flour.

2. Vibro sifter is used for flour sifting

Flour is also the main raw material for refined foods such as bread and cakes. Due to the requirements of the production process, flour is required to have sufficient fluffiness when making fluffy refined pastries without agglomeration. At this time, a flour shaker is required to screen the flour. Generally, it is required to use a 40-mesh sieve to sift the flour.

Vibro sifter, as a flour vibrating sieve with high precision, not only can easily screen the impurities of flour, but also has a significant effect on flour sifting, which fully meets the needs of customers for this screening, but the screening output is not as good as straight-line flour The vibrating screen is large, generally 200-300 kg/h. In addition, in order to improve the quality and economic value of flour, many flour mills will further select the flour products to improve the fineness and precision of flour. The sieving accuracy is required to be 400 meshes, and the vibro sifter can be easily processed. For high-precision screening equipment within 400 mesh, it plays a very important role in the selection of flour.

3. Linear vibro sifter is used for rough cleaning of flour

The linear vibro sifter is mainly a device for particle classification and screening. It has the obvious advantages of high output and high screening efficiency, but the fineness of the screening is not as good as the vibro sifter. The linear vibro sifter used in flour mills is generally not used for high-precision screening, but is the same as the direct discharge sifter, used to treat larger impurities similar to certificates, thread ends, etc., and the screening output is basically the same as that of the same model. The direct discharge flour shaker is comparable, but its cost is much lower than the direct discharge sifter. Therefore, customers who prefer low prices often use a straight flour shaker to replace the direct discharge sifter, but it should be noted that this The current linear screens must be made of stainless steel to meet the sanitary requirements of the food industry.
