Abstract
The invention relates to the technical field of material storage, and in particular relates to a method for storing rapeseeds by dormancy. The method for storing rapeseeds by dormancy comprises the following steps of: firstly, ventilating a material storage bin by a strong ventilating device, wherein the moisture of seeds is less than 7% and the temperature is lower than 18 DEG C; and then, injecting nitrogen to the material storage bin and then, hermetically storing by heat insulation, wherein the bin is isolated from oxygen. According to the method for storing rapeseeds by dormancy provided by the invention, the airing amount of labor of farmers and input of airing fields can be alleviated, the rapeseeds in plants, grain depots and grain purchasing points are prevented from heating, mildewing and brooding, and problems in long-term storage of rapeseeds are solved. Meanwhile, according to the storage method by dormancy, the vitality of seeds is stopped, the consumption is extremely less, and complete nutritional components of rapeseeds are reserved. The method for storing rapeseeds by dormancy provided by the invention is simple and accessible, easy to operate and low in cost, and can be widely applied to the storage of oil plant crops of rapeseed, soybean and the like and crops such as wheat and rice paddy.
Description
Technical field
The present invention relates to material storage technical field, relate to specifically a kind of method of dormancy oil in reserve vegetable seed.
Background technology
At present, the rapeseed of selling on market is subjected in harvesting that shortage, a rapeseed material and other staple food grain in impact, rural laborer, airing place of sleety weather is less to be unfavorable under the factors such as airing is even season, cause rapeseed substantially there is no airing after harvesting, caused on market the moisture of tank oil vegetable seed very inhomogeneous generally between 8%-20%.National standard safe storage rapeseed moisture should be below 8%.If rapeseed moisture surpasses 8%, when temperature surpasses 0 ℃, the vitality of seed is in a kind of state of sprouting, if will germinate this moment in soil, if be deposited in together due to the temperature reason, exceed more than 8 ℃ moisture smoothly discharge can cause the rapeseed heating mouldy, infested, have a strong impact on quality and the nutrition of Seed Vitality and product oil.
Summary of the invention
The objective of the invention is the deficiency for the prior art existence, provide a kind of infested problem that solves heating in the rapeseed storing process, goes mouldy to reach the method for dormancy oil in reserve vegetable seed.
The method of a kind of dormancy oil in reserve of the present invention vegetable seed is achieved by following technical proposals: a kind of method of dormancy oil in reserve vegetable seed, it is characterized in that: described method is first to ventilate to material bin with forced ventilation equipment, make the moisture of seed less than 7%, temperature is less than 18 ℃; Seal again heat insulation preservation then for the material bin nitrogen injection, make in the storehouse isolated with oxygen.
The method of a kind of dormancy oil in reserve of the present invention vegetable seed has following beneficial effect compared with prior art: storage method of the present invention is first to clean before putting in storage totally; evenly enter material bin; the generation of anti-classification, anti-layering; then decide air quantity, fix time, fixed temperature, decide humidity and take a breath in the external world to rapeseed with forced ventilation equipment; simultaneously at seed moisture content less than 7%; temperature during less than 18 ℃ nitrogen injection seal again heat insulation preservation; make in material bin to completely cut off with oxygen, reach the purpose that protects Seed Vitality.The method of a kind of dormancy oil in reserve of the present invention vegetable seed can alleviate peasant's the airing amount of labour and the input in airing place, prevent factory, grain depot, grain purchases point rapeseed heating, go mouldy, infested, the problem that has existed in having solved that rapeseed is long-term and storing.Simultaneously the banking system of dormancy method makes the vitality of the seed state that seizes up, consume few, the reservation of sending out the complete nutritional labeling of rapeseed.
Method is simple for a kind of dormancy oil in reserve of the present invention vegetable seed, processing ease, and cost is low, can be widely used in the storage of the crops such as the oil crops such as rapeseed, soybean and wheat, paddy rice.
The specific embodiment
Below in conjunction with embodiment, the method and technology scheme of a kind of dormancy oil in reserve of the present invention vegetable seed is further described.
The method of a kind of dormancy oil in reserve of the present invention vegetable seed is first to ventilate to material bin with forced ventilation equipment, makes the moisture of seed less than 7%, and temperature is less than 18 ℃; Seal again heat insulation preservation then for the material bin nitrogen injection, make in the storehouse isolated with oxygen.
The intake of described ventilation is 2-10 times of rapeseed cumulative volume in the storehouse for the air quantity that per hour enters material bin; Time is to take a breath 2-6 time every day, each 1-2 hour; Temperature for when rapeseed moisture higher than 7% the time, the ventilation temperature that enters material bin is no more than 50 ℃; When rapeseed moisture reached standard, outdoor normal temperature can directly be taken a breath lower than 18 ℃, and outdoor normal temperature changes to lower than 18 ℃ of air with water at low temperature under refrigeration machine or land used during higher than 18 ℃; Humidity for when seed moisture content greater than 7%, outside air humidity need often open blower ventilation less than 60% the time, makes rapeseed moisture be down to 5%-7%; In material bin, nitrogen injection seals heat insulation preservation to gas again in order to give when seed moisture content, temperature reach requirement after, makes that in the storehouse, seed and oxygen completely cut off; Again input low temperature, dry nitrogen during higher than 18 ℃ when temperature in the storehouse.
Embodiment 1.
Put in storage and frontly first rapeseed is cleaned totally; evenly enter material bin; prevent the generation of classification, layering; then decide air quantity, fix time, fixed temperature, decide humidity and take a breath in the external world to rapeseed with forced ventilation equipment; simultaneously at seed moisture content less than 7%, temperature during less than 18 ℃ to material bin in nitrogen injection seal again heat insulation preservation; make seed and oxygen in the storehouse isolated, reach the purpose that protects Seed Vitality.
1, decide air quantity: the air quantity that per hour enters material bin is 2-10 times of rapeseed cumulative volume in the storehouse;
2, fix time: according to the variation of temperature, humidity in a day, take a breath 2-6 every day, and each 1-2 hour, reach rapeseed moisture, the appropriate effect that reduces of temperature, rapeseed moisture, temperature can be down in standard in 15 days;
3, fixed temperature: when rapeseed moisture was high, the ventilation temperature that enters material bin was no more than 50 ℃; When rapeseed moisture reached standard, outdoor normal temperature can directly be taken a breath during lower than 18 ℃, when outdoor normal temperature during higher than 18 ℃ with refrigeration machine or land used under water at low temperature change to air lower than 18 ℃;
4, decide humidity: greater than 7% the time, outside air humidity need often be opened wind less than 60%, and rapeseed moisture is down between 5%-7% when seed moisture content;
5, decide gas: after seed moisture content, temperature reach requirement, seal again thermal insulation in material bin nitrogen injection and preserve, make that seed and oxygen completely cut off in the storehouse in, reach the purpose of long-term dormancy oil in reserve vegetable seed.Higher than 18 ℃, again input the nitrogen of low temperature, drying when temperature.
