1. Parameters
2. Results
3. Variation by machine throughput
Shows the entered throughput plus two reference points below and above it, in 5 t/h intervals.
Formulas used — Water
Water per ton = [1,000 × (100 − initial moisture) ÷ (100 − target moisture)] − 1,000
Hourly flow = water per ton × throughput per hour
Flow per minute = hourly flow ÷ 60

2. Application result
Calculation used
Product dose per ton = target (CFU/t) ÷ product guarantee (CFU/g or CFU/mL).
Solution per hour = solution volume (L/t) × throughput (t/h).
Solution concentration = product dose per ton ÷ solution volume per ton.
Calculator based on the sieving method used by Granucalc/Embrapa and ANSI/ASAE S319.4 methodology. Roll-range diagnosis uses operational references .
1. Drying and moisture determination
: 150 g.| Step | Elapsed time | Weight (g) |
|---|---|---|
| 1st weighing | 60 min | |
| 2nd weighing | 75 min |
Operating criterion : two consecutive weighings with a maximum variation of 0.1 g. If the reduction is greater, repeat 15-minute cycles until stable.
2. Sieve weighing
| Fraction / sieve | Opening | Retained weight (g) | Retained (%) |
|---|---|---|---|
| > 3,36 mm | 3.360 µm | — | |
| 2,00–3,36 mm | 2.000 µm | — | |
| 1,00–2,00 mm | 1.000 µm | — | |
| 0,50–1,00 mm | 500 µm | — | |
| Pan (< 0.50 mm) | 37 µm* | — | |
| Total sieved | 0,00 g | 100% | |

📘 Manual — sampling, drying, weighing and sieving
- Sampling: build a representative sample with small collections at different times during the batch. Mix without crushing the particles.
- Subsample: separate 150,0 g and record the initial weight.
- Drying: spread the sample evenly and dry at 110 °C por 60 minutos.
- First weighing: remove, allow to cool protected from moisture, and weigh.
- Stability: return for 15 minutos, cool and weigh again. Repeat 15-minute cycles until two consecutive weighings vary by no more than 0,1 g.
- Moisture: DM (%) = dry weight ÷ initial weight × 100. Moisture (%) = 100 − DM.
- Sieving: after drying and cooling, sieve without crushing the sample. Recover and weigh all material retained on each sieve and in the pan.
- Recording: enter retained weights. The calculator automatically determines percentages, DGM and DPG.
Note: this is an operating protocol for field standardization. For official laboratory reports or research, use the analytical method/standard required by the responsible laboratory.
High-moisture grain: higher moisture may increase retention on the upper sieves. Interpretation should consider moisture, roll configuration, adjustment and material condition. No automatic mathematical correction of DGM for moisture is applied.
