<p>A method of cleaning pollen from mechanical impurities, spore and micro-organisms is based on the fact that dirty pollen ( 1 ) is sucked to air flow via an insulant sieve ( 2 ). Clean pollen ( 3 ) falls into a filter ( 6 ), dirt ( 5 ) sticks on the sieve ( 2 ). The pollen cleaning device consists of a sucking unit ( 7 ) with a filter ( 6 ), before which at least one sieve ( 2 ) with a throttle flap ( 8 ) is located.</p> |
