Confectionary Seeds Selecting Line – 30 Tons/Day Pre-Roasting Solution for Turkish Food Firm

This confectionery seed selection line was built for a Turkish food firm and specialises in the pre-roasting processing of confectionery seeds, including sunflower, pumpkin and watermelon seeds. It is tailored to meet the country's strict standards for snack-grade seeds and the firm's production target of 30 tonnes per day.

How It Processes Confectionary Seeds for Roasting

The line’s streamlined workflow ensures consistent pre-roasting quality while hitting 30 tons/day output:

• Initial cleaning: Raw confectionery seeds first pass through the TQSX-125 Grain De-Stoner. This machine uses gravity separation to remove stones and heavy impurities, which is critical for protecting downstream equipment and preventing bitter residues in roasted seeds.
• Precision Sorting: All seeds (dehulled and whole) enter the 5XZ-1480B Blow Type Gravity Separator, where adjustable air flow and density sorting isolate undersized, and then Color Sorter remove discolored or low-quality seeds – ensuring only uniform, high-purity seeds proceed to roasting.
• Final Grading: A multi-layer screen sifts seeds by size, matching the firm’s specific roasting machine requirements (e.g., 8-10mm for pumpkin seeds, 5-7mm for watermelon seeds).

Key Performance Metrics

• Daily Capacity: Steady 30 tons (3.75 tons/hour over 8-hour shifts), exactly meeting the firm’s pre-roasting demand for their confectionary production line;
• Sorting Purity: ≥4% for all confectionary seed types (up from 93% with their old manual sorting process), ensuring consistent roasting results;
• Efficiency: Cuts pre-roasting preparation time by 40% vs.

This solution addressed the client’s need for reliable pre-roasting seed quality. Their old process often produced uneven seeds, resulting in inconsistent roasting and burnt or underdone batches. Now, with uniform, high-purity confectionery seeds feeding their roasting line, the firm has reduced waste by 25%, expanded its snack product range to three new retailers in Istanbul and boosted quarterly sales by 35%.
