Pollen dryer 15-20kg (10 trays)

01 · TEMPERATURE

The machine reaches 90 °C; the pollen does not

The machine adjusts from 30 to 90 °C. To preserve sensitive pollen constituents, Bogdanov recommends drying at the lowest possible temperature, with a maximum of 30 °C. Traditional drying practices use 40 °C, but do not preserve those constituents as well.

There is no universal boundary between preserving everything at 40 °C and damaging it at 45 °C: temperature, time and the batch all matter. Check the actual temperature in the drying area and avoid direct sunlight.

02 · THE LOAD

A thin layer, not a full tray

The stated load is 1.5–2 kg per tray and 15–20 kg fresh pollen per batch, spread thinly to about 2 cm at most. Dry weight depends on initial moisture: for example, 20 kg at 25% moisture would yield about 16 kg at 6%, allowing only for water loss.

The stated 6–12 hours is an indication, not a guarantee for every load or setting. Check samples from several trays; if drying is uneven, review the load distribution and airflow before declaring the batch finished.

03 · THE END POINT

6% as a process reference

Bogdanov’s drying reference is 6 g of water per 100 g of pollen. Campos gives 6–8% as a tentative maximum in a proposed standard, not a storage guarantee. Above 10%, susceptibility to fermentation increases; further drying does not always improve texture. Verify moisture using a method suitable for pollen.

Let the pollen cool before closing the container, in clean, dry surroundings. Our guide gives 10–14 minutes of cool airflow as a reference: adapt this to the load and the machine’s available functions. That duration alone guarantees neither cooling nor storage stability.

04 · THE MACHINE

304 stainless, 1,000 W and all of it removable

The trays and everything that touches the pollen are food-grade 304 stainless steel and go in the dishwasher, which is what lets you move from one lot to the next without carrying residues across.

It runs on 220 V at 1,000 W with a quiet fan, so its place is the honey house and not the apiary. The LED panel sets the time in 30-minute steps and the temperature in steps of 5 degrees.

05 · BEFORE YOU BUY

A dryer only solves half the problem: the other half is collecting daily and getting there soon.
