Abstract:
Seed Extraction and Post-Harvest Handling of Seeds – Theory
This presentation will provide an overview and considerations related to harvest maturity, the seed extraction process, seed sanitation and drying of fruited seed crops of vegetable seeds.  Discussion will include critical control points involved and the equipment associated with each step from harvest through seed drying.  A brief overview of the pre-cleaning process after the seeds are dried will also be included.

Abstract:
Fundamental Concepts for Cleaning and Upgrading Seed
Review of post-harvest seed cleaning processes that utilize a series of dry granular separation processes and adjustments to compensate for variations in size, shape, and other characteristics.  Typical equipment varies by crop and production requirements but often includes an air-screen cleaner, various sizing or shape separation devices, gravity tables for density separation, and possibly optical sorting machinery. Understanding the capabilities of each machine and interaction within a cleaning system can help maximize removal of undesirable material while retaining more good seed suitable for intended market requirements.
