Perfect Seed in Practice: Flexible Cleaning, One-Step Processing and High-Performance Calibration

Seed producers face increasing complexity: more crop species and varieties, smaller lots, stricter purity requirements and frequent changeovers often combined with challenging size distributions that make calibration inefficient. This PETKUS Academy seminar presents practical, next-generation mechanical cleaning and calibration concepts to achieve Perfect Seed.
First, we explain how modern air-screen cleaning systems enable flexible sieve configurations for both seed and fine seed processing. Participants will learn how to select and combine sieve functions to match different crops and quality targets, and how faster changeovers and practical design features support efficient day-to-day operation.
Second, we present a one-step approach that combines cleaning and calibration in a single machine. This concept reduces process steps, simplifies plant layout and helps lower handling effort-supported by a real market example.
Third, we discuss high-capacity sieve calibration when grade ratios are unfavourable. Using a maize example, we show how multi-grade calibration (e.g., four size fractions) can be achieved in one machine replacing multiple traditional steps while maintaining stable quality and throughput.
The session is practice-oriented, featuring concrete process examples, typical pitfalls and selection guidelines, helping participants translate product requirements into robust mechanical sorting strategies.
