Pollen pini drying and sand-impurity-removing method

Abstract

The present invention discloses a method for drying pollen pini and removing sand and impurity. Said method includes the following steps: (1) cleaning and heating air; (2). mixing hot air with pollen pini together and making the steps of drying and removing sand; (3). after the pollen pini is undergone through the processes of drying and removing sand and impurity making first air-powder separation to separate out most of pollen pini; and (4) making the air which contains small quantity of pollen pini and is discharged from first-slage separation tower undergo the process of secondary air-powder separation treatment so as to completely separate out pollen pini; and the air temp. in the drying process can be regulated.

Description

1. Technical field [0001] The invention discloses a method for drying and removing sand and impurities of pine pollen, and belongs to the technical field of drying and removing impurities of pine pollen. 2. Background technology [0002] Pine pollen refers to the male reproductive cells of Pinus massoniana, Pinus tabulaeformis or several plants of the same genus. Pine pollen belongs to wind-pollinated pollen, which is mainly collected manually. When the pine pollen just shakes off from the flower spike, the water content is 20 Between -25%, it is not easy to store, and it must be dried to make the water content below 8%, so that it can be stored for a long time; moreover, pine pollen is rich in nutrients, some of which are unstable under high temperature or sunlight. It is very easy to be destroyed, so when the pine pollen is dried, the temperature is not easy to be too high; at present, the drying of pine pollen is generally dried by natural air drying, atmospheric circulat...

Problems solved by technology

[0002] Pine pollen refers to the male reproductive cells of Pinus massoniana, Pinus tabulaeformis or several plants of the same genus. Pine pollen belongs to wind-pollinated pollen, which is mainly collected manually. When the pine pollen just shakes off from the flower spike, the water content is 20 Between -25%, it is not easy to store, and it must be dried to make the water content below 8%, so that it can be stored for a long time; moreover, pine pollen is rich in nutrients, some of which are unstable under high temperature or sunlight. It is very easy to be destroyed, so when the pine pollen is dried, the temperature is not easy to be too high; at present, the drying of pine pollen is generally dried by natural air drying, atmospheric circulation drying or drying by dehumidifiers, electric ovens, etc., and they all exist to varying degrees. Problems or deficiencies, such as long drying time; greatly affected by weather changes, pine pollen is prone to mildew in rainy days; the moisture content of pine pollen is not easy to control during the drying process; when the drying temperature is too high or the drying time is long, it is easy to cause loss of nutrients. loss, etc., and there is currently no effective method for removing sand from pine pollen except screening; all of these hinder the effective utilization of pine pollen
