Vibro Sifter for Sieving Sesame

Sesame is one of the common main oil crops in our country. Whether it is white sesame or black sesame, it has the characteristics of high nutritional value and wide edible use. However, because the sesame particles are relatively small, they are easily mixed with pod shell sand during harvest. , It affects the economic value and use value of sesame, and some deep processing technology has the need for peeling sesame. The application of vibro sifter can greatly improve the efficiency and precision of impurity removal and screening, but the vibro sifter model of sesame impurity removal corresponding to different purposes is also The differences, let's introduce them one by one in detail:

When raw sesame seeds are harvested, there will always be a lot of impurities such as branches, leaves, pods, and sand. The presence of impurities will not only seriously affect the quality of deep-processed products such as oil extraction, but also because of impurities when they are sold. Too much and the price drop is great, so the removal of impurities is very important.

For pod husks, small growers will dry the sesame husks to let the sesame seeds come out by themselves, but this is obviously not suitable for farmers who grow sesame seeds on a large area, and because of the small sesame particles, it causes sandy soil and broken branches. The screening of crushed leaves is also very difficult, manual screening is time-consuming and laborious, and the accuracy is difficult to guarantee. If a sesame vibrating screen is used, these problems can be easily solved.

Commonly used sesame vibrating screens for impurity removal are mostly linear vibrating screens, which are also commonly used types of grain removal vibrating screens. On the one hand, they are determined by the large particle nature of food products; on the other hand, they are related to the height of linear vibrating screens. The high-efficiency and high-precision screening characteristics are directly related. The linear vibrating screen is driven by dual vibrating motors and has a large-area screen with a proper aspect ratio. When the two vibrating motors rotate synchronously and in opposite directions, the exciting force generated by the eccentric mass is parallel to the axis of the motor. Cancel each other, stack in the direction perpendicular to the motor shaft to form a resultant force, and the trajectory of the screen machine is a straight line. The two motor shafts have an inclination angle relative to the screen surface. Under the combined force of the exciting force and the self-gravity of the material, the sesame seeds are thrown up on the screen surface and move forward in a straight line, so as to achieve the purpose of screening and grading the sesame seeds.

In addition to the removal of raw sesame seeds, the crushed pieces of cooked sesame seeds during the frying process are also screened using a linear vibrating screen.

Application of round vibro sifter in sesame peeling process

Under normal circumstances, the deep processing of sesame does not need to be peeled, but when sesame is used in the production of food and sesame cake, it must be peeled, because the fiber and oxalate content in the seed coat or stratum corneum (2%) ～3% calcium oxalate chelate) is relatively high, and it has a bitter taste when used.

Sesame peeling methods include flotation separation and mechanical separation. The vibrating screening machine plays a role in sesame peeling by using mechanical peeling, that is: the soaked sesame seeds are installed vertically through two pieces with a hard surface 1 -The surface of the disc, one disc is fixed, the other disc rotates, the wet seeds are removed from the kernel by friction, and then the mixture is washed by water stream or water spray, and then sieved from the mixture by a vibrating sieving machine Out of the skin.

This process usually uses a circular vibro sifter, that is, a rotary vibrating screen, because the circular vibro sifter has the outstanding feature of high screening accuracy. It uses a vertical motor as the excitation source, and the upper and lower ends of the motor are installed with eccentricity. The heavy hammer converts the rotating motion of the motor into a horizontal, vertical, and inclined three-dimensional motion, and then transmits this motion to the screen surface. Adjusting the phase angle of the upper and lower ends can effectively change the trajectory of the sesame hull on the sieve surface, helping the peeling process to be smooth and precise.

Its characteristics are as follows

1. The impurity removal rate reaches 95%, and the inorganic impurity removal rate reaches 98%.

2. It has the advantages of beautiful appearance, compact structure, convenient movement, obvious dust and impurity removal efficiency, low energy consumption, simple and reliable use.

3. The screen of the vibrating screen can be changed arbitrarily according to user requirements. The commonly used meshes in the sesame industry are 10/14/16/18 meshes.

4. One machine with multiple functions, can be filtered or graded, and the number of grades can reach up to 6. It also has a professional cleaning effect on soybeans, millet, rice, garlic, red dates and other crops.
