Workers climb, open bags or drums, and transfer flour or other powder ingredients by hand. The process is slow, exposes raw material to contamination, and often delays the start of production. When the ovens are ready, but the ingredients are still being shifted into the plant, valuable production time is lost.
A pneumatic unloading and screening solution changes that equation. Instead of relying on manual handling, a truck equipped with a pressure-rated silo connects directly to the plant’s pneumatic conveying line. A blower supplies positive air pressure that pushes the material through a sealed pipeline. In the middle of this pipeline sits the Sivtek Pressure Screen, a machine built to operate inside the pressurised system. As the powder travels under pressure, the screen performs a crucial quality step removing oversized particles or foreign matter before the material reaches the mixing or blending stage.
This approach delivers two operations in one pass. The same air pressure that moves the flour from the truck to the production floor also powers a real-time check screening. There is no need for separate equipment or additional transfer steps. The outcome is quicker, cleaner and more regulated movement of the material of the delivery truck up to the biscuit dough mixers.
For plant managers, the benefits are clear:
- Faster start-ups. Bulk ingredients go from truck to process line in a matter of minutes so production teams can start work immediately upon delivery.
- Better product quality. Unwanted particles and oversized lumps are removed automatically, protecting the consistency of dough and final biscuits.
- Improved hygiene and safety. A dust-free sealed pipeline prevents contamination that might otherwise come from manual dust collecting, or any form of dust.
- Lower labour costs. Fewer people are needed to handle and screen raw material.
Traditional unloading can take hours and ties up workers who could be focusing on core production tasks. With a positive-pressure pneumatic line and the Sivtek Pressure Screen, unloading and check screening happen in a single continuous operation. Biscuit manufacturers can reduce waiting times, reduce human intervention, and maintain the top quality expected by customers.
For plants looking to speed up production and add a layer of quality assurance without complicating their process, this combined unloading and screening system is a direct route to efficiency. It turns a routine delivery into a swift, controlled step that feeds the ovens faster and keeps biscuit production running on schedule.
