Stevia leaf drying is the first step for both whole-leaf sweetener products and steviol glycoside extraction. Extractors buy dried leaf on glycoside content, especially rebaudioside A, so growers want drying that is quick and even. Large plantations harvest whole stems, making stem separation part of the drying plan.
To dry stevia leaves, GEM recommends the Band Dryer (Beltotherm). Typical moisture is 70–80% in the feed and 8–10% after drying. Single-Pass Conveyor Dryer and Multi-Pass Conveyor Dryer are used when the feed or site calls for it. Every project starts with a pilot trial on your own sample.
A Beltotherm band dryer handles plantation-scale stevia as an even, permeable bed of stems and leaves, drying fast enough to stop fermentation. Single-pass dryers suit smaller farms or stripped leaves; multi-pass units save floor space.
| Typical feed moisture | 70–80% |
| Typical target moisture | 8–10% |
| Recommended dryer | Band Dryer (Beltotherm) |
| Alternatives | Single-Pass Conveyor Dryer, Multi-Pass Conveyor Dryer |
| Application area | Herbal, Botanical & Nutraceutical |
| Industries | Nutraceuticals & Herbal, Food & Beverage |
Glycoside content sets the price extractors pay. Quick, controlled drying prevents fermentation losses, cuts dependence on weather and lets growers sell graded leaf at a premium.
Plants searching for a stevia leaf dryer or comparing a stevia drying machine usually need three answers: which dryer fits, what it costs to run, and how fast it pays back. For Stevia Leaves, we start from your throughput, current moisture (typically 70–80%) and the target (8–10%), trial a sample on the Band Dryer, and return a sized recommendation with a budget quotation for your nutraceuticals and food operation.
We trial your material in our pilot facility before any equipment decision, then size the dryer from real data.
Describe it in the form, or message an engineer directly.
