Semsam Seed Sieve

What is Semsam Seed Sieve

Raw sesame is often mixed with soil, sand, metal chips, glass fragments, etc. These impurities not only affect the taste, but may also cause harm to human health. The screening machine can effectively remove them to ensure the food safety of sesame products.

The reason why Semsam Seed Sieve is used for sieving sesame is that it can efficiently and thoroughly remove various impurities in sesame, thus bringing many important benefits.

The role of Semsam seed screen in sesame screening process

In the sesame processing technology, raw sesame is often mixed with sand, straw, stones, unripe seeds, broken seeds and light shells and other impurities. If it is directly put into the frying or oil pressing stage without sufficient screening, it will not only affect the quality and taste of the finished sesame oil, but also cause equipment wear or blockage. Therefore, Semsam seed screen plays a key role in the entire sesame primary processing.

Remove all kinds of impurities: Whether it is large pieces of straw soil, fine sand and dust, or even heterochromatic grains and metal impurities that are difficult to distinguish with the naked eye, they can be effectively separated through different types of Semsam seed screens.

Improve the purity of sesame: After multiple screenings, the purity of sesame can be greatly improved, which is directly related to the taste, flavor and hygiene safety of the final product.

Ensure product quality and safety: Removing harmful impurities (such as stones and metals) is the key to ensuring consumer food safety; removing moldy and heterochromatic grains can improve the overall quality and commodity value of sesame.

What can Semsam seed screens be used for?

The application of Semsam seed screen in sesame screening is mainly reflected in the process of cleaning, grading and pre-treatment of sesame in families or small oil mills. Its key role is to remove impurities, improve purity, protect downstream equipment (such as oil presses) and improve the quality of the final product.

Before sesame oil pressing or frying, sesame usually needs to be sieved to remove impurities such as fine sand, straw, and seed shell fragments. As the core tool in this step, Semsam seed screen is equipped with a fine and uniform screen. Through manual or electric vibration, sesame seeds are layered and moved on the screen surface. Small particles or debris fall from the screen holes, while intact sesame seeds remain on the screen surface to achieve primary screening.

In the entire process, the sesame screening machine plays a role in accurate grading, effective impurity removal, purity improvement, and protection of subsequent frying and oil pressing equipment. After treatment, the impurity content of sesame seeds is reduced from the original 2.3% to less than 0.1%, which significantly improves product quality and oil output efficiency.

What is the working principle of Semsam seed screen?

The Semsam seed screen drives the eccentric block to rotate at high speed through the motor, generating three-dimensional or linear vibration, so that sesame seeds jump and move quickly on the screen:

The raw materials fall on the screen surface after feeding; the vibration motor drives the screen body to vibrate at high frequency;

Sesame particles slide or fall along the screen holes according to their size; fine impurities (such as dust and fine sand) smaller than the screen holes fall to the lower layer or bottom; sesame seeds that meet the size move along the screen and are discharged from the discharge port; multiple layers of screens can be set to achieve multi-level classification such as coarse screening, medium screening, and fine screening.

Semsam seed screen model parameters

Structural composition of Semsam seed screen

Screen frame: The frame that supports the screen, generally welded with steel to ensure that the overall structure is strong and stable.

Screen: It is composed of stainless steel wire mesh or punched plate, and the screen aperture is customized according to the sesame particle size and screening requirements.

Vibration device: includes a vibration motor and an eccentric block, which generates vibration force through rotation, causing the sesame to continuously jump and move on the screen to achieve screening.

The support spring or shock absorber is installed under the screen frame to support the screen body and absorb vibration to reduce the impact on the ground.

Feed inlet and discharge port: The feed inlet is used for sesame to enter the screening machine, and the discharge port is divided into a qualified particle outlet and an impurity outlet to discharge different materials respectively.

Material application examples of Semsam seed sieve

Before sesame oil pressing or frying, sesame seeds usually need to be sieved to remove impurities such as fine sand, straw, and seed shell fragments. As the core tool in this step, the Semsam seed sieve is equipped with a fine and uniform screen. Through manual or electric vibration, the sesame seeds are moved in layers on the screen surface, small particles or debris fall from the screen holes, and the complete sesame seeds remain on the screen surface to achieve primary screening.

Taking a family oil press as an example, 500 grams of raw sesame seeds are pre-screened with a matching stainless steel seed screen. The screening process lasts about 2-3 minutes and can remove about 2% of fine impurities and broken seeds. This step significantly reduces the residue blockage during the oil pressing process and avoids the wear of the oil pressing screw by gravel. At the same time, the surface of the sieved sesame seeds is cleaner, the frying process is more uniform, and the oil yield and oil quality are improved.
