Course Description: This course focuses on the management and maintenance of quality grains and oilseeds. It includes lectures on quality factors of value-added grains and oilseeds; moisture content determination; grain sampling and quality standards; quality assured production of IP grains; relationship between air and grain properties; fan selection and operational management for drying, conditioning and aerating grains; grain storability, deterioration and mycotoxins; insect pest identification; pest management strategies for prevention and control; and Sanitation, Loading, Aeration and Monitoring (S.L.A.M.)-based stored grain management.

Course Goals: GEAPS 520 teaches students the basic principles of managing the quality of value-added grains during post-harvest handling, drying and storage. By the end of this course, students will be familiar with different methods of quality control and management systems and understand the grain-grading standards required to maintain quality and prevent potential problems.

Target Audience: GEAPS 520 is designed for grain-elevator professionals responsible for assessing, managing and maintaining grain quality, including those involved with storing and conditioning, aeration, drying, pest control and mycotoxin management.

The Course of Study

Week 1
Lecture 1 – Grain Quality Properties
This lecture will introduce students to quality factors of value-added grains and oilseeds, including both physical properties and chemical properties. Main topics will include: physical grain quality properties, the chemical grain quality properties and the effect of quality properties on biological processes. It will discuss the primary grain properties in each of the three categories of grain quality, moisture content's effect on friction coefficient and angle of repose, the difference between the piling and funneling angle of repose, and the primary flow patterns of grain when emptying from a bin.
Lecturer: Dr. Richard Stroshine & Dr. Dirk Maier

Lecture 2 – Moisture Content
In this lecture, students will learn the importance of moisture-content determination, including how to define moisture content and dry basis, versus wet-basis moisture. Students will also learn about grain blending calculations and acceptable moisture to blend grains.
Lecturer: Dr. Richard Stroshine & Dr. Dirk Maier

Week 2
Lecture 3 – Grain Inspection and Quality Standards
This lecture will give students an introduction to grain sampling principles and equipment. Students will also learn about the purposes and types of grain grading standards and a comparison of U.S. grading standards versus international grading standards. In addition, students will understand the quality factors that are included in the grading standard as well as the factors that are not applicable to standards.
Lecturer: Dr. Dirk Maier

Lecture 4 – Air Properties, Equilibrium Moisture Content and Airflow Part I
After this lecture, students will understand the concepts of air properties (psychometrics) and grain properties (equilibrium moisture content) and the importance of airflow rates for drying, conditioning and aerating (cooling) grains and oilseeds.
Lecturer: Dr. Dirk Maier

Week 3
Lecture 5 – Air Properties, Equilibrium Moisture Content and Airflow Part II
Students will continue to learn the concepts of air properties (psychometrics) and grain properties (equilibrium moisture content) and the importance of airflow rates for drying, conditioning and aerating (cooling) grains and oilseeds. The lecture will focus on utilization of tools to calculate EMC values.
Lecturer: Dr. Dirk Maier

Lecture 6 – Fan Sizing, Selection and Operational Strategies
The objective of this lecture is for students to be able to understand the importance of proper fan sizing and selection to achieve desired operational effects. The lecture provides an overview of fan types, and basic principles of fan sizing and selection. Basic operational strategies that can be employed to dry, condition and aerate grains are also covered.
Lecturer: Dr. Dirk Maier

Week 4
Lecture 7 – Storability and Deterioration of Grains and Oilseeds
This lecture will familiarize students with the storability concept and the primary causes of grain deterioration due to molds and mycotoxins. It will touch on several topics including: the definition of mycotoxins, the factors that lead to mycotoxin problems, changes that occur in grain when damaged by mold, management steps in the prevention of grain spoilage, how to determine if grain is contaminated with mycotoxins, the allowable storage time concept, the causes of grain deterioration and the primary storage molds (fungi). In addition, new ways to test for mycotoxins are covered.
Lecturer: Dr. Charles Woloshuk

Lecture 8 – Insect Pests of Stored Grains and Oilseeds
Lecture 8 will cover the different stored-product insect pests and how to identify them. Topics will include how to correctly identify pest species, major internal and external infesting pests, what pest species to be concerned about, federal regulations, "good" insects, why internal pests are harder to monitor and control, factors that regulate insect populations and which insect populations can be controlled.
Lecturer: Dr. Linda Mason

Week 5
Lecture 9 – Prevention and Control of Stored Product Insect Pests
This lecture will familiarize students with the primary pest control strategies, including fumigation. It will cover the importance of cleaning prior to loading a grain bin; pest management options for before, during and after loading the grain; influences on fumigation's success; how some control strategies fail; and reducing your risk and increasing your efficiency during a fumigation. It will also discuss residual grain protectants, alternative stored product protectants, grain fumigants and grain fumigation principles. In addition, new technologies available for the control of insect pests will be covered.
Lecturer: Dr. Linda Mason

Lecture 10 – S.L.A.M.-Based Quality Management of Stored Grains and Oilseeds
Students will become familiar with principles of SLAM (Sanitation, Loading, Aeration and Monitoring) for optimum quality management of stored grains and oilseeds. The main topics covered include using sanitation to clean storage structures, loading a storage structure properly, using aeration to cool grains, and how to monitor to check grain properly
