Chapter 28: Roll Mill Fig Diagram of the flow of different seed in a roll mill. Fig Screening vibratory conveyor, and diagram of 168 dimensions and discharge spouts. It is impossible to make a complete or artificial separation of different aspects of seed conditioning. Bill Gregg has managed seed conditioning programs, done research on development and design of machines, helped manufacturers of equipment, written operation and maintenance manuals, trained managers and operators, and helped design and install many seed plants in several countries.

Fig Side-view cross-section of the stoner deck. Fig Center of gravity of seed of different shapes. As conditions volume, crop seed, costs, etc. Fig Flow of air from inlets, through a narrow band of 99 seed to the outlets. Fig When too much air is forced up through the gravity deck. Fig Diagram of a slotted cylinder in a Carter Precision 558 Grader grading corn for thickness. Seed conditioning removes undesirable material including debris and stray seeds from selected raw harvested seed, so as to create planting seed that delivers high yielding crops.
Fig Side view of proper installation of a gravity separator 527 with counterbalances. Fig Side view of the three shelling units. Yet with all this, seed conditioning still remains the aspect of the seed industry which is something of an art. Fig Pipe attachments for dusty air exhaust. A seed production is also a business enterprise, and it must operate efficiently and generate a profit while serving farmers. Fig The same air-screen cleaner can be used for many 367 different seed kinds.
Fig A modern mist application device that can be used 791 standing alone or with a mixing chamber. Fig The rod and flighting mixing chamber section of a 791 typical continuous flow treater. Information is organized so that it will be readily available and findable when needed. Information also was not available on all models and brands; Some companies did not provide materials, while others were quite generous in supporting this work. Seed conditioning removes undesirable material including debris and stray seeds from selected raw harvested seed, so as to create planting seed that delivers high yielding crops.
Fig A high-capacity corn sheller used in larger 274 conditioning plants. Fig Salvaging good seed from the middlings fraction, by 519 having three gravity separators. Fig Small-capacity air-screen cleaner using revolving 337 horizontal cylindrical screens. Fig A combination vibrating conveyor and scalper. All have utility in certain installations. To the extent possible, each discussion is complete, without requiring cross-references to other sections. Fig Adjusting the stroke speed.
Chapter 36: Vibrator Separator Fig Discharge end of an experimental vibrator separator. Chapter 9: Moving Seed in Conditioning Fig. Fig Common flow sequence for machine-delinting of 296 cottonseed. All seed production, handling and supply operations require efficient application of good management and high technology. Chapter 41: Horizontal Disk Separator Fig An experimental model of the horizontal disk separator. Fig Sheet metal section details of piping dusty air from fans. It describes the essential information needed to understand this process and the machinery involved.
Fig Construction details of a small view window. Gary Gillups is President of Crippen International which has installed seed plants in all continents except Antarctica. Fig Diagram of the steps in initial start-up adjustments 514 on a rectangular gravity. Polishers do not separate seed; they gently rub the cleaned seed to remove dust, discolorations, etc. Fig A belt-type continuous-flow dryer. In recent years much information has been developed on improving seed through conditioning. Fig The test weight apparatus.
