Pollen dryers

Pollen driers should bring the water percentage of pollen to less than 10%. They are composed of superimposed sieves in which the pollen is spread in layers of less than one centimeter thick. A stream of air sent by a fan over a heating element heats up and then passes through the pollen. A thermostat, not to exceed 45 º C and sometimes a water absorber, complete the dryer.
