Abstract
The invention relates to the technical field of seed processing, in particular to a spring onion seed picking process. The spring onion seed picking process includes the steps of dispersing, threshing, screening and cleaning, postprocessing and the like. The spring onion seed picking process specifically includes using a spike-tooth type thresher to disperse spring onion flower balls and removes large flower ball residues such as branches, receptacles and leaves to form dispersed mixtures mainly comprising petals and seeds; adopting a two-stage serially-connected cylinder dryer to dry the mixtures at the lower temperature, and completing threshing by means of petal syneresis; adopting a two-stage serially-connected air-screen cleaner to screen and clean to acquire pre-selected seeds; performing postprocessing such as drying, packaging, storing and transporting on the pre-selected seeds according to production requirements to acquire raw seeds. According to the spring onion seed picking process based on the characteristic that the seeds can shed due to petal syneresis, the lower-temperature drying technology is adopted to accelerate petal syneresis, so that seed picking efficiency is improved, seed quality is guaranteed, and effective supply of the raw seeds is realized. The spring onion seed picking process can be widely applied to production of the spring onions.
Description
Technical field
The present invention relates to seed processing technique field, particularly about a kind of onion seeds, get seed technique.
Background technology
Shallot is one of important vegetable crop of China, has very large cultivated area, yet shallot breeding cycle is long and the seed storage time limit shorter (room temperature storage is devitalization in 1～2 year), and onion seeds market demand is huge.Onion seeds supply is the prerequisite that ensures that shallot produces, and raw material seed supply is the basis of seed large-scale production.Shallot is spherical inflorescence, after seed maturity, from the seed ball (bouquet) of plant top cracking, naturally comes off.Onion seeds collecting time is short, bouquet water content high (more than 30%), if can not process in time, will badly influence seed quality, and onion seeds grain is little, light weight, and scale takes off seed operational difficulty.Tradition onion seeds is got seed method and is: shallot bouquet makes moisture reduction cause that petal shrinks by natural drying after plucking, seed is naturally deviate from petal, then manually clean the mixture acquisition raw material seed that seed, bouquet remaining (petal, holder, branch stalk etc.) etc. form, through following process, become commercial seed.Tradition onion seeds get seed technique exist affected by environment large, production capacity is low, labour intensity is large, seed is selected the problems such as rate is low, seed quality is unstable; cannot adapt to scale seed and produce, the effective supply of raw material seed becomes the bottleneck of restriction onion seeds industry development.
Summary of the invention
For the problems referred to above, the object of the invention is to provide a kind of onion seeds and gets seed technique, to improve onion seeds, gets seed efficiency and seed quality, realizes the effective supply of raw material seed, meets seed large-scale production needs.
For achieving the above object, the present invention is based on petal seed this characteristic that can come off while shrinking, adopt low temperature drying technology to accelerate petal syneresis, improve and get seed efficiency and guarantee seed quality.The present invention is by the following technical solutions: a kind of onion seeds is got seed technique, and it comprises following operation: (1) working in dispersion; (2) de-seed operation; (3) operation is cleaned in screening; (4) post processing.In described operation (1), use spiketooth type thresher to carry out shallot bouquet working in dispersion remaining except the larger bouquet such as discarding stalk, holder, Bao Ye, form that to take petal, seed be main loose shape mixture; In described operation (2), adopt two-stage series connection roller drying machine to implement low temperature drying to mixture, by petal syneresis, realize de-seed operation, in first order warm air drier, set up broken shaft to improve the separating effect of seed and petal, flight is set to improve drying efficiency in the warm air drier of the second level; In described operation (3), adopt two-stage series connection air-screen separator to sieve and clean operation, first order air-screen separator is for separating of larger impurity such as petals, and second level air-screen separator, for separating of compared with small impurities, sieves and cleans rear acquisition preliminary election seed; In described operation (4), preliminary election seed according to production requirement dry, pack, store, the post processing such as transportation becomes raw material seed.
The invention has the beneficial effects as follows: based on petal, shrink the characteristic that seed can come off, adopt low temperature drying technology to accelerate petal syneresis, can improve and get seed efficiency and guarantee seed quality, realized the effective supply of onion seeds raw materials for production seeds.The present invention can be widely used in onion seeds production.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention is based on petal and shrink the characteristic that seed can come off, adopt low temperature drying technology to accelerate petal syneresis, improve and get seed efficiency and guarantee seed quality.The onion seeds the present invention relates to is got seed technique and is comprised working in dispersion, de-seed operation, sieves and clean the operations such as operation, post processing.
It is as follows that the onion seeds the present invention relates to is got seed technique embodiment:
(1) working in dispersion: because onion seeds is positioned at plant top bouquet, the de-seed manipulating object of onion seeds is the shallot bouquet of manually gathering.First use spiketooth type thresher to carry out shallot bouquet working in dispersion remaining except the larger bouquet such as discarding stalk, holder, Bao Ye, form that to take petal, seed be main loose shape mixture.
(2) de-seed operation: rely on petal syneresis to realize de-seed operation, adopt two-stage series connection roller drying machine mixture to be implemented to low temperature drying, s main working parameters: 1 ton/hour for the treatment of capacity, 150 ℃～180 ℃ of warm air drier inlet temperatures, outlet temperature are less than 40 ℃, drying time period approximately 15 minutes.In first order warm air drier, set up broken shaft to improve seed and petal separating effect; In the warm air drier of the second level, set up and stir flight to improve drying efficiency.
(3) operation is cleaned in screening: because seed rate in mixture is relatively little, adopt two-stage series connection air-screen separator to sieve and clean operation, first order air-screen separator is for separating of larger impurity such as petals, second level air-screen separator, for separating of compared with small impurities, sieves and cleans rear acquisition preliminary election seed.
(4) post processing: preliminary election seed according to seed production requirement dry, pack, store, the post processing such as transportation becomes raw material seed.
In sum, the present invention is based on petal and shrink the characteristic that seed can come off, adopt low temperature drying technology to accelerate petal syneresis, improve and get seed efficiency and guarantee seed quality, realized the effective supply of onion seeds raw materials for production seeds.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the invention process, and not departing from design spirit and scope of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
