Lesson 1Reception and intake: objectives, equipment (weighbridge, intake conveyors, magnetic separators), control variables (weight, moisture, documentation)Looks at intake aims, sampling, and record checks, plus scales, conveyors, and magnetic cleaners. Focuses on managing weight, dampness, and tracking to avoid mix-ups and dirt.
Reception quality and safety objectivesTruck scheduling and traffic managementWeighbridge operation and calibrationSampling, grading, and moisture testingMagnetic separation and foreign body controlLesson 2Milling: objectives, equipment (roller mills, hammer mills, degerminator), control variables (roll gap, speed, throughput, temperature)Covers milling goals from size reduction to quality traits. Compares roller and hammer mills plus degermers. Stresses settings for gaps, speed, flow, and heat for steady meal quality.

Details fillers, bagging, detectors, and checks for weight, seals, and dampness in final goods.
Packaging objectives and material selectionWeigh-filler calibration and accuracy checksBagging line setup and seal integrity testsMetal detection and foreign body controlFinished product storage and rotation rulesLesson 4Sieving and classification: objectives, equipment (plansifters, sifters), control variables (mesh sizes, vibration amplitude, yield by fraction)Explains sorting aims for size control and better yields. Covers plansifters, mesh choices, shakes, and tracking output per grade and sieve work.
Sieving objectives and cut point definitionPlansifter layout and flow diagramsMesh size selection and maintenanceVibration amplitude and sieve loadingYield by fraction and efficiency trackingLesson 5Storage in silos: objectives, equipment (aeration, temperature sensors, level indicators), control variables (bulk moisture, temperature, insect activity)Details silo goals to keep quality and stop rot. Reviews air flow, temp and level checks, and handling dampness, hot spots, bugs via checks and logs.
Storage objectives and risk assessmentSilo design, loading, and unloading patternsAeration system setup and operationTemperature and level sensor managementInsect monitoring and fumigation basicsLesson 6Dispatch: objectives, paperwork and logistics controls (lot numbering, QC release, transport conditions)Outlines dispatch aims for right orders, tracking, protection. Covers papers, batch numbers, quality okay, and checks on trucks, seals, clean loading.
Dispatch planning and customer requirementsLot numbering and full traceabilityQC release, certificates, and recordsLoading checks and vehicle hygieneTransport conditions and seal controlLesson 7Cleaning and sorting: objectives, equipment (scalpers, aspirators, destoners, optical sorters), control variables (impurity rate, grain size, airflow, vibration)Covers cleaning to remove dirt and even out grain. Details scalpers, suckers, stone removers, light sorters, and settings for trash, size, air, shakes.
Cleaning and sorting performance objectivesScalpers and coarse impurity removalAspirators and airflow adjustmentsDestoners and density based separationOptical sorters and defect detectionLesson 8Drying: objectives, types of dryers (continuous tray, rotary, fluidized bed), control variables (inlet/outlet temperature, residence time, moisture setpoints)Describes drying for longer life and safety, comparing tray, rotary, fluid beds. Focuses on in/out heat, stay time, dampness targets to avoid too dry or wet.
