Description
Technical field
This scheme relates to a kind of small lot corn ear Quick-air-drying equipment for corn variety seed selection that laboratory is used that is applicable to, mainly for breeding link.
Background technology
The corn drying machinery of selling is in the market mainly used in commodity food dries, and also there is no the corn ear dryer of breeding special use.And commercially available dryer mainly has following characteristics: the one, for drying corn kernel; The 2nd, volume is large, oven dry amount is large, cannot be for the test baked seed of negligible amounts; The 3rd, temperature is high, dewatering speed is fast, dries the activity that can affect corn seed for corn seed; The 4th, thermal source used is mainly coal, fuel oil or other biological matter fuel.
In corn breeding process, there is special feature: first the amount of being is few, be badly in need of developing the laboratory special equipment of the automation that is suitable for a small amount of baked seed of many kinds and guarantees not mix; The 2nd, corn seed is fruit ear, is not seed, and air-dry speed is slow and inside and outside inconsistent; The 3rd, in air drying process, must guarantee the activity of maize seed, so temperature is had to specific (special) requirements, must not be over 40 ℃; The 4th, drying time is as far as possible short, after the seed species test of being convenient to gather in the crops northern summer, adds for breeding to Hainan; The 5th, forbid to mix mutually, guarantee purity.
In view of crop breeding feature, test less by corn seed amount, between different seeds, to forbid to mix, dewatering speed can not be too fast, and bake out temperature should not be too high, otherwise the easy inactivation of seed keeps the higher germination percentage of seed after drying.Based on above feature, existing corn drying machinery has the feature of the following aspects to be unsuitable for breeding baked seed: the one, and what corn seed was gathered in the crops is fruit ear, water content too high (35% left and right) can not threshing, threshing badly broken by force, the machinery of drying for seed be not suitable for corn ear and dry; The 2nd, the grain weight in breeding process is few, between different seeds, can not mix, and the dryer of existing rotation, stirring-type is unsuitable for testing baked seed; The 3rd, the target that existing drying plant is pursued is dewatering efficiency, and needn't keep seed activity, so dehydration efficiently easily causes FCR de-vitalizing seed, breeding research work cannot be continued; The 4th, test seed treatment place is that laboratory is not large-sized workshop, is not suitable for utilizing fire coal, combustion gas, fuel oil or other biological fuel as thermal source raw material.
Utility model content
In order to solve the deficiency of existing equipment and technology, the utility model provides a kind of corn ear Quick air drier, for testing the flash baking of seed fruit ear and drying rear its seed activity that keeps.
The utility model solves the technical scheme that its technical problem adopts:

The specific embodiment
Corn breeding demand, the general single cropping of enterprise more than medium Breeding Scale is cultivated combination 20,000 left and right, can produce 2.4 ten thousand parts of new seed, the every part of about 3-5 fringe of seed left and right.Quantity is quite huge.
In order to accelerate corn breeding paces, northern area, China Guangxi all utilizes Hainan to add for breeding, due to Hainan climatic characteristic, generally will at the bottom of September, left and right sowing be advisable, and late sowing causes setting percentage to decline because latter temperature is too high.Therefore after northern area harvest corn, to dry as early as possible rear species test, to add generation to Hainan.Corn content large (reaching 30-35% left and right) during north corn (especially Huang-Huai-Hai region) results, weather is not easy to dry easy going mouldy and makes seed devitalization.If dry, need larger place, and be easy to mix, and run into the rainy larger workload that increased.So utilize cluster drying machine to carry out baked seed, safe and efficient, generally within 3-4 days, baked seed can be reached to species test condition, compared with dryness in the sun, shorten about 30 days, be just in time suitable for the numerous sowing needs of South of Hainan.
The biological characteristics of corn seed drying course: corn is in cereal crop seed, belong to large semina, the volume of embryo almost accounts for 1/3 left and right of whole seed, and weight accounts for 10%～12% of wholegrain, owing to containing more hydrophilic group in embryo, than the easier moisture absorption of endosperm.In the situation that seed moisture content is higher, the moisture of embryo is higher than endosperm, and the embryo of dry seed, moisture is but lower than endosperm.Therefore water imbibition is stronger, and respiratory capacity is more much bigger than other seed corns, the poor stability during oven dry.
Corncob is in milking maturity and wax ripeness stage soft and succulency.When ripe, the superficial cell lignifying of axle becomes hard, and axle center (marrow) tissue is but very soft, and permeability is better, has stronger hygroscopicity.Seed raw on cob, and the size of its moisture is decided by cob to a certain extent.Moist cob moisture is greater than seed, and dry cob moisture is few than seed.Therefore the too fast cob water content that may cause of dewatering speed is too high, makes on the contrary seed absorption cob moisture and causes moisture to raise.Therefore based on corn seed feature, need dewatering speed moderate, evenly the breeding tailored version cluster drying machine of dehydration.
