Coffee roasting and roasting equipment
Common roaster parts and design elements
Names of processes and changes
Use common terminology to describe a coffee roaster, its operation, and the changes that occur during the roasting process.
Common features and controls on drum roasters
Identify common design elements of a coffee roaster Describe how air moves through a roasting system and how control manipulations can affect the roast.
THE ROASTING PROCESS
Describe the order and coffee roasting process with the physical progression of the changes to the coffee that occur in roasting. Identify that such changes determine the roast level.
Change in color
Change in size
Record time, temperature and other relevant data on roast logs along with observations during and after a roast record:
Temperature at time (roast profile)
Colour of roasted coffee
Produce a roast profile and description of the properties of a roasted coffee
Identify the use of a roast profile as a tool to support quality control processes and to determine if a roast is acceptable
Calculate development time and temperature midway point
How to record and calculate specific events during the development of a complete roast cycle.
Temperature midway point
Identify critical events during a roast cycle to enable calculation of development time Calculate and record different transformational phases of roast development
The relationship between flame and roast speed and their measurement on the roast log
The heat source heats up the air and the roast chamber which in turn heats up the beans so the speed of the temperature increment depends on the heat source settings during the roast. So the following causal succession applies
Discuss the basic effects of time and heat on roast development Predict what changes in heat application are needed to effect a change in the flavor of a roasted coffee
Logging/documentation information about the roast
Identify what information should be placed in the Roasters Guild roast log (adjust to regional variations)
Sensorial changes that occur during roasting
Basic color changes that occur during the roasting process and the taste associated with them
Describe basic tastes and aromas associated with different roast colours
SAFETY AND MAINTENANCE
Safety in the roasting plant
Common dangers in the roasting process, including roaster fires, ventilation and personal safety
Recognize the common dangers involved in the roasting process Describe the preventative measures and corrective actions to ensure safety in the workplace
Roaster cleaning and maintenance
Consult the manual
Identify and describe the regular cleaning and maintenance requirements of a roaster Identify the importance of reading and being familiar with the coffee roaster manual
