GEAPS 610: Interpretation of Process Flow Diagrams
2019 course offerings:
- May 14 – June 18 – Registration closed May 8
Registration is currently closed.
Course Description: GEAPS 610 focuses on interpretation, use and creation of process-flow diagrams, especially in grain-handling and grain-processing facilities. Featuring animation, the course will discuss the purposes, benefits and limitations of flow diagrams, and then investigate how diagrams depict processes in facilities devoted to grain-handling, feed processing, grain dry milling, and wet-process separation. At the end of the course, students will be required to develop their own relatively simple flow chart. The course is not intended for experts, but it will require some math.
Course Goals: This course teaches participants how to interpret and use process-flow diagrams, and shows how they are applied in various grain and processing facilities. The course identifies and discusses the process steps and types of equipment that flow diagrams may depict, as well as diagram symbols and nomenclature. GEAPS 610 will enable participants to use flow diagrams to identify and understand capabilities and restrictions in a process, and covers the concept of mass balance. The course also discusses how flow diagrams help visualize and manage critical-control points for food safety and other considerations. The final lecture asks students to create a flow diagram in response to instructions.
Target Audience: GEAPS 610 is designed for grain and processing facility operators and supervisors, maintenance supervisors, trainees, quality-control officials, HACCP inspectors, government inspectors, company management and others wanting to understand process-flow diagrams and how they are applied. Note: The course is not intended for those with sophisticated knowledge of process-flow diagrams, but will require some math.

Course of Study
Lecture 1 – Introduction: Flow Diagram Purposes and Functions
Before the course moves into details and applications, Lecture 1 will set the stage with a discussion about the main purposes and values of flow diagrams, how they’re used to organize, define, sequence and depict the steps in a grain facility process, and describe some of the main symbols used. The lecture will also introduce a simple flow diagram.
Lecturer: Fred Fairchild
GEAPS members can access this lecture for free in the GEAPS Knowledge Resource Center.
Lecture 2 – Capabilities, Limitations and Plant Safety
What sorts of information can a flow diagram provide? What are the limitations? This lecture will investigate the informative capabilities of flow diagrams, how they can be applied, and where they may not be useful. It will show how flow diagrams are used to identify and list equipment pieces and capacities at a facility, and examine how diagrams can be used to promote plant safety.
Lecturer: Fred Fairchild
Lectures 3 – Flow Diagrams for Grain-Handling Functions
Lecture three (as well as lectures four, five and six) get specific, investigating how flow diagrams are used to represent and illustrate the processes, equipment, capabilities, functions and sequences at various facility types. This lecture will introduce and discuss flow diagrams for whole-grain handling, storing, drying and cleaning. Students will follow an actual flow diagram to see how the processes, functions and steps are depicted and tied together. The lecture will also introduce the topic of critical control points. What are the facility’s limitations for reaching production goals? Where in the process (and facility) are the limitations? Where is there potential compromise in safety?
Lecturer: Allan Tedrow
Lecture 4 – Flow Diagrams for Feed Processing
This lecture will introduce and discuss flow diagrams for feed-processing facilities. Students will follow an actual flow diagram to see how a feed-processing plant’s functions and steps are depicted and tied together. The lecture will also cover critical control points. What are the feed facility’s limitations for reaching production goals? Where in the process (and facility) are the limitations?
Lecturer: Alok Singh
Lecture 5 – Flow Diagrams for Grain Dry Milling
Lecture five will introduce and discuss flow diagrams for dry-grain milling processes, including those used with corn and other grains, as well as to produce flour. Students will follow an actual flow diagram to see how a milling plant’s functions and steps are depicted and tied together. The lecture will cover critical control points.
Lecturer: Jason Watt
Lecture 6 – Flow Diagrams for Wet Process Separations
Lecture six will introduce and discuss flow diagrams for grain wet milling, ethanol fermentation, oilseed crushing and oil extraction. Students will use a flow diagram to discuss, identify and understand the processes and investigate the key process control points.
Lecturer: Connie Hardy
Lecture 7 – Investigating Equipment Requirements
Information in a flow diagram can help identify equipment requirements, including capacities and capabilities, and this lecture will show how. It will also discuss how flow diagrams are used to create automated, computer-screen depictions that allow equipment- and process-monitoring and troubleshooting, as well as making assessments about plant modifications such as retrofitting or expanding.
Lecturer: Fred Fairchild
Lecture 8 – Mass Balance: Quantity In Equals Quantity Out
Lecture eight will help students understand the term “mass balance,” and how flow diagrams are used to illustrate, monitor and account for physical, chemical and biological properties of ingredients as they pass through a plant. Students will work through several numeric examples, using flow diagrams presented in the specific process lectures.
Lecturer: Kortney Wagner
Lecture 9 – Working With an Example
To help ensure that students understand basic concepts, this segment will provide students with a real-world process-flow diagram, and then ask them to respond to specific questions. What steps are needed to perform a certain function? What is the routing? What equipment is being used? How do you troubleshoot a given problem?
Lecturer: Jason Watt
Lecture 10 – Drawing a Flow Diagram
In the final segment of the course, students will be asked to draw a relatively simple flow chart in response to given details. The diagram should show all main steps, sequences, equipment and processes needed. Some students may be able to use computer-aided programs to produce the diagram, but freehand done neatly works, too.
