Pollen cleaning method and a device applying this method

Abstract

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.

1 . A method of cleaning pollen from mechanical impurities, spores and microorganisms, comprising by that the contaminated pollen ( 1 ) is sucked to airflow through an insulant sieve ( 2 ), while the clean pollen particles ( 3 ) fall into a filter ( 6 ) where they are caught, and the impurities ( 5 ) stick on the sieve ( 2 ).  
   
   
       2 . The method of cleaning pollen according to  claim 1  comprising by that the amount of sucked contaminated pollen ( 1 ) and speed of its sucking to the air flow is regulated by a throttle flap ( 8 ) placed before the sieve ( 2 ).  
   
   
       3 . A pollen cleaning device consisting of a sucking unit with a filter comprising by that at least one insulant sieve ( 2 ) and at least one throttle flap ( 8 ) are arranged before the filter ( 6 ) input.  
   
   
       4 . The device according to  claim 3  comprising by that it is arranged inside an underpressure chamber ( 9 ) equipped with an underpressure ventilator ( 10 ), while the outlet ( 11 ) of the sucking unit ( 7 ) is led outside the underpressure chamber ( 9 ).  
   
   
       5 . The device according to  claim 3  comprising by that the sieve ( 2 ) is interchangeably fitted on the input of a vertical sucking strainer ( 12 ) led to the filter ( 6 ) and the throttle flap ( 8 ) consists of a perforated board touching the sieve ( 2 ).  
   
   
       6 . The device according to  claim 5  comprising by that perforation of the throttle flap ( 8 ) consists of circular or oval holes of different diameters arranged into a circle or an oval.  
   
   
       7 . The device according to  claim 3  comprising by that it moreover contains a heating board ( 13 ) on which a work board ( 14 ) for the contaminated pollen ( 1 ) is arranged, a sweeping plate ( 15 ), spoon ( 16 ) for ladling the contaminated pollen ( 1 ) and its application on the sieve ( 2 ), and a brush ( 17 ) with a dust bin ( 18 ) for removing dirt ( 5 ) from the sieve ( 2 ) surface.  
   
   
       8 . The device according to  claim 3  comprising by that it is equipped with a cover ( 19 ) fitting to the sucking strainer ( 12 ) with the sieve ( 2 ) and fitted with a sucking lead ( 20 ), for sucking remainders of contaminated pollen ( 1 ) from the work board ( 14 ).
