Beneficial effects of the present invention are illustrated below by way of test example:
The test of 1 winnowing machine selection by winnowing choice of parameters of test example
Rhodiola seed is by harvesting, rubbing, primary dcreening operation, fine screen and impurity and kind after removing lime-ash in seed mix Sub- size shape is close, only difference in weight, can not be separated by sieving.It can only be separated by selection by winnowing.
To look for optimal selection by winnowing parameter, this test is provided with following several processing:
Fan blade revolving speed is 120 revs/min, rate of feeding 3g/s;
Fan blade revolving speed is 90 revs/min, rate of feeding 3g/s;
Fan blade revolving speed is 60 revs/min, rate of feeding 3g/s;
Fan blade revolving speed is 40 revs/min, rate of feeding 3g/s;
Fan blade revolving speed is 120 revs/min, rate of feeding 1g/s;
Fan blade revolving speed is 90 revs/min, rate of feeding 1g/s;
Fan blade revolving speed is 60 revs/min, rate of feeding 1g/s;
Fan blade revolving speed is 40 revs/min, rate of feeding 1g/s.
Fan blade revolving speed is adjusted by the buncher that winnowing machine carries in processing, and rate of feeding passes through blanking switch plate Knob is adjusted.
The result shows that:
When speed rotation of the fan blade with 120 revs/min, 90% or more rhodiola certified seed is blown by high wind It is discharged, can not separate with impurity from air outlet to air outlet;
When fan blade is with the rotation of 90 revs/min of speed, only about 20% rhodiola certified seed is from discharge port One discharge, about 60% certified seed go out to drop out from discharge port two, still have about 20% certified seed to be discharged from air outlet, nothing Method separates well with impurity;
When speed rotation of the fan blade with 40 revs/min, certified seed is all dropped out by discharge port one, but discharge port one Physical purity of seed could not separate with most of impurity down to 30%, can not apply to practical selection by winnowing;
When speed rotation of the fan blade with 60 revs/min, physical purity of seed has reached 90% or more in the product of discharge port one, And there was only the certified seed of a small amount of (5% or less) in two product of discharge port, only impurity is without certified seed in air outlet.
When rate of feeding is 1g/s and 3g/s in this test, the product of discharge port one and two is therefore excellent without significant change Selecting rhodiola seed selection by winnowing parameter to arrange for rate of feeding is 1-3g/s, and fan blade revolving speed is 60 revs/min.
To sum up, the rhodiola seed cleanliness of the method for the present invention, acquisition is high, good quality.
