Dryer for drying grape pollen

Abstract

The invention belongs to the field of instruments for gardening and the like, and particularly relates to a dryer for drying grape pollen. The dryer comprises a box body, a cover body, a drying sieve, a pollen box and a paperweight sieve; the box body comprises an air baffle and an air inlet sieve which are connected with the inner wall and the outer wall, and a filtering cavity and a drying cavity are defined; an air inlet pipe is arranged at the lower part of the outer wall, is communicated with the filter cavity and is connected with a nitrogen machine; a plurality of air holes are formed in the air baffle, and air holes are formed in the inner wall, close to the air baffle, of the drying cavity; air holes are formed in a top sieve of the pollen box; a space for drying pollen is defined by the pollen box and the drying sieve; air holes are formed in the paperweight screen and are matched with the air holes in the pollen box; filter paper is placed between the pollen box and the paperweight screen and between the pollen box and the drying screen; a hollow abutting column with the closed bottom is arranged in the center of the lower portion of the cover body. The method can effectively prevent the pollen from caking and oxidation, and can ensure the maximum activity of the dried pollen.

Description

technical field [0001] The invention belongs to the fields of horticulture, agronomy and other instruments, in particular to a drier for drying grape pollen. Background technique [0002] The pollination methods of plants are divided into self-pollination and cross-pollination. In addition, in horticultural production, cross-pollination between different varieties is required, that is, hybridization. However, due to differences in varieties and planting regions, the flowering period of the same genus is also different; therefore, it is difficult for these varieties to hybridize in a natural state, such as grapes. Grape flowers are relatively small, and the amount of pollen is also low; in hybrid breeding, tedious and intensive labor such as detasseling and pollination is required, and each step is related to the fruiting rate of hybridization. In the cross-breeding of grapes, we need to preserve the pollen to achieve cross-breeding of grapes with different flowering periods...

AI Technical Summary

Problems solved by technology

However, grape pollen also contains more sugar and polyphenols, which are easily oxidized during the drying process, causing browning and clumping; this reduces the activity of pollen and further reduces the success rate of subsequent pollination ; and finally, a great deal of manual labor yields very little
