Description
Technical field
The present invention relates to seeds processing technical field, particularly get seed technique about a kind of onion seeds.
Background technology
Shallot is one of important vegetable crop of China, has very large cultivated area, but shallot breeding cycle is long and the seed storage time limit is shorter (room temperature storage i.e. devitalization in 1 ~ 2 year), and onion seeds market demand is huge.Onion seeds supply is the prerequisite ensureing that shallot produces, and raw material seed supply is then the basis of seed large-scale production.Shallot is spherical inflorescence, naturally comes off after seed maturity from the seed ball (bouquet) of plant top cracking.Onion seeds collecting time is short, bouquet water content high (more than 30%), will badly influence seed quality, onion seeds grain is little, light weight if can not process in time, and scale takes off seed operation difficulty.Tradition onion seeds is got seed method and is: shallot bouquet makes moisture reduction cause petal to shrink by natural drying after plucking, seed is naturally deviate from petal, then the mixture manually cleaning the composition such as seed, bouquet remnants (petal, holder, branch stalk etc.) obtains raw material seed, becomes commercial seed through following process.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 produces, 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, gets seed efficiency and seed quality, realizes the effective supply of raw material seed, meet seed large-scale production needs to improve onion seeds.
For achieving the above object, the present invention is based on seed when petal shrinks and can to come off this characteristic, adopt low temperature drying technology to accelerate petal syneresis, improve and get seed efficiency and ensure seed quality.The present invention is by the following technical solutions: a kind of onion seeds gets 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 and except the larger bouquet remnants such as discarding stalk, holder, Bao Ye, formed based on the loose shape mixture of petal, seed; In described operation (2), two-stage series connection roller drying machine is adopted to implement low temperature drying to mixture, de-seed operation is realized by petal syneresis, set up broken shaft in first order warm air drier to improve the separating effect of seed and petal, flight is set in the warm air drier of the second level to improve drying efficiency; In described operation (3), adopt two-stage series connection air-screen separator to carry out screening and clean operation, first order air-screen separator is for separating of larger impurity such as petals, and second level air-screen separator is for separating of comparatively small impurities, and rear acquisition preliminary election seed is cleaned in screening; The post processings such as in described operation (4), preliminary election seed carries out drying according to production requirement, pack, store, transport become raw material seed.
The invention has the beneficial effects as follows: the characteristic that can come off based on petal contraction seed, adopts low temperature drying technology to accelerate petal syneresis, can improve and gets seed efficiency and ensure seed quality, achieve the effective supply of onion seeds raw materials for production seed.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 the characteristic that petal contraction 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 that the present invention relates to is got seed technique and is comprised working in dispersion, de-seed operation, sieves and clean the operation such as operation, post processing.
It is as follows that the onion seeds that the present invention relates to gets seed technique embodiment:
(1) working in dispersion: because onion seeds is positioned at plant top bouquet, it is the shallot bouquet of manually gathering that onion seeds takes off seed manipulating object.First use spiketooth type thresher to carry out shallot bouquet working in dispersion and except the larger bouquet remnants such as discarding stalk, holder, Bao Ye, formed based on the loose shape mixture of petal, seed.
(2) de-seed operation: rely on petal syneresis to realize de-seed operation, two-stage series connection roller drying machine is adopted to implement low temperature drying to mixture, main working parameters: treating capacity 1 ton/hour, warm air drier inlet temperature 150 DEG C ~ 180 DEG C, outlet temperature are less than 40 DEG C, drying time period about 15 minutes.Broken shaft is set up to improve seed and petal separating effect in first order warm air drier; Set up in the warm air drier of the second level 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 carry out screening and clean operation, first order air-screen separator is for separating of larger impurity such as petals, second level air-screen separator is for separating of comparatively small impurities, and rear acquisition preliminary election seed is cleaned in screening.
(4) post processing: the post processing such as preliminary election seed carries out drying according to seed production requirement, pack, store, transport becomes raw material seed.
In sum, the present invention is based on the characteristic that petal contraction seed can come off, adopt low temperature drying technology to accelerate petal syneresis, improve and get seed efficiency and guarantee seed quality, achieve the effective supply of onion seeds raw materials for production seed.
It should be noted last that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the invention process or equivalent replacement, and not departing from design spirit and scope of the present invention, it all should be encompassed in the middle of right of the present invention.
