A food processing customer in Palestine required a reliable solution for sesame seed screening with high precision and stable throughput. The main challenges included fine screening at 1 mm, maintaining a capacity of 1 ton per hour, and reducing material temperature before screening to ensure smooth operation and product quality.
To meet these requirements, we recommended and customized a double-deck rotary vibratory screen (vibratory separator) specifically designed for sesame seed processing.
Material: Sesame seeds
Screening mesh size: 1 mm
Capacity: 1 ton/hour
Industry: Food processing
Accurate 1 mm screening to remove impurities
Stable and continuous output of 1 TPH
Cooling assistance during feeding to improve material flow
Reduced material accumulation on the screen surface
Based on the material characteristics and production conditions, a two-layer vibratory separator was custom-engineered with the following features:
Upper deck: Pre-screening and removal of oversized impurities
Lower deck: Fine screening at 1 mm to ensure consistent product quality
A fan was installed at the feeding inlet to provide airflow and assist with material cooling
Effectively lowers the sesame seed temperature before screening
Improves flowability and enhances screening efficiency
A return plate was added between the screen layers
Optimizes material movement across the screen surface
Prevents local material buildup and improves screening stability
After commissioning, the vibratory screen operated smoothly and continuously. The system consistently achieved the required 1 ton per hour throughput, with precise 1 mm separation. The cooling fan effectively reduced the impact of elevated material temperature, while the return plate improved screen utilization and reduced downtime.
The customer reported improved screening efficiency, stable operation, and reliable product quality.
This project demonstrates how a customized rotary vibratory screen with cooling and material flow optimization can significantly enhance sesame seed screening performance. Tailored design solutions ensure high efficiency, stable output, and consistent quality in food processing applications.
