Abstract
The invention discloses a rapid and continuous preparation method of organic fertilizer. The method comprises the steps that 1, excrement of livestock and poultry and crushed straw are uniformly mixed in proportion to form a mixed material; 2, the mixed material is put in a constant-temperature environment of which the temperature is 65 DEG C-80 DEG C and the moisture content is 60%-68% to be continuously fermented for 24 hours; 3, the fermented mixed material is put in a sealed environment at the temperature of 120 DEG C-250 DEG C under the pressure of 0.15 MPa-4 MPa to be continuously decomposed at the high temperature for 15 minutes; 4, the decomposed mixed material is dewatered and dried. According to the continuous preparation method of the organic fertilizer, the preparation cycle is significantly shortened, the floor space needed by composting fermentation is reduced, and then the production efficiency of the organic fertilizer is improved; in addition, residual harmful pathogenic bacteria, worm eggs and the like in the organic fertilizer can be effectively killed through the fermenting environment at the temperature of 60 DEG C-75 DEG C and the high-temperature decomposing environment at the temperature of 120 DEG C-250 DEG C, and therefore harmless continuous production of the organic fertilizer is achieved.
Description
Technical field
The present invention relates to organic fertilizer technical field, be specifically related to the quickly continuous preparation method of a kind of fertilizer.
Background technology
The feces of livestock and poultry farm directly discharges, and environmental pollution is very big, and traditional way is to build a large-scale manure pit, gives Crops in Applying Fertilizer inside the Excreta of poultry being left in after natural fermentation.Its weak point is: for larger plant, need the manure pit that excavation floor space is huge, and, owing to the natural fermentation cycle of feces of livestock and poultry is long, and, the fertilizer also not readily transportable circulation that fermentation maturity is good, this allows for fertilizer and is wasted, and goes back severe contamination surrounding enviroment simultaneously.
In order to make full use of the feces of livestock and poultry of plant, what have carries out artificial fermentation to feces of livestock and poultry, after then passing through a series of process, makes packed bio-organic fertilizer and comes into the market.In the prior art, the production of biological organic fertilizer is generally based on compost fermentation.But, owing to compost need to through very long temperature rise period, hot stage, temperature-fall period and become thoroughly decomposed the stage etc., whole fermentation time was up to 60-90 days (particularly low temperature season) so that the manufacturing cycle of fertilizer is longer, took bigger compost place；And, owing to the maximum temperature of compost natural fermentation is usually no more than 60 DEG C, the fermentation making fertilizer is not thorough, being difficult to hamlessizing technology, the harmful levels of pathogens of residual, worm's ovum etc. in prepared fertilizer, if directly applying to crops, easily pathogenic insect pest, it addition, by the impact of various extraneous factors, compost fermentation is difficult to continuously uninterrupted production.
Summary of the invention
For the above-mentioned problems in the prior art, now provide the quickly continuous preparation method of the fertilizer that a kind of manufacturing cycle is short, degree thorough, innoxious of becoming thoroughly decomposed is high.
Concrete technical scheme is as follows:
The quickly continuously preparation method of a kind of fertilizer, has the feature that, including: the first step, feces of livestock and poultry and crushing straw is uniformly mixed to form mixed material in proportion；Second step, mixed material is placed in temperature be 65 DEG C～80 DEG C, moisture content be 60%～68% environment in continuous fermentation 24 hours；3rd step, the mixed material completing fermentation is placed in temperature be 120 DEG C～250 DEG C, pressure be 0.15MPa～4MPa sealed environment in continuous high temperature become thoroughly decomposed 15 minutes；And the 4th step, the mixed material dehydrate become thoroughly decomposed will be completed.
Further, in the quickly continuous preparation method of fertilizer provided by the invention, it is also possible to have the feature that, in second step, mixed material is continuous fermentation in fermentation tank, and, fermentation tank is maintained constant temperature by the chuck that water temperature in outside sandwich is 65 DEG C～80 DEG C.
Further, in the quickly continuous preparation method of fertilizer provided by the invention, it is also possible to having the feature that, in the third step, mixed material continuous high temperature in the horizontal tank that becomes thoroughly decomposed becomes thoroughly decomposed, and, the tank that becomes thoroughly decomposed is by sheathed heater heat temperature raising.
Further, in the quickly continuous preparation method of fertilizer provided by the invention, it is also possible to have the feature that, the interlayer of chuck heating is injected with steam, conduction oil or electrical heating.
Further, in the quickly continuously preparation method of fertilizer provided by the invention, it is also possible to have the feature that, in second step, mixed material is placed in the isoperibol that temperature is 65 DEG C～80 DEG C rapid continuous fermentation.
Further, in the quickly continuously preparation method of fertilizer provided by the invention, it is also possible to have the feature that, in the third step, mixed material be placed in the sealed environment that temperature is 120 DEG C～250 DEG C quick continuous high temperature becomes thoroughly decomposed.
Further, in the quickly continuous preparation method of fertilizer provided by the invention, it is also possible to have the feature that, also include the 5th step, dry mixed material is carried out pelletize, packaging.
Having the benefit effect that of technique scheme
In the quickly continuous preparation method of fertilizer provided by the invention, by straw and feces of livestock and poultry mixing match are formed fertilizer, it is possible to obtain good carbon-nitrogen ratio, moreover it is possible to avoid the atmospheric pollution because crop straw burning brings.And, fertilizer is placed in temperature be 65 DEG C～80 DEG C, moisture content be carry out continuous fermentation under the constant temperature of 60%～68%, the environment of constant humidity, which overcome compost to heat up the shortcoming of slow uneven, fermentation time length again, complete the fertilizer of fermentation continue temperature be 120 DEG C～250 DEG C, pressure be 0.15MPa～4MPa sealed environment in continuous high temperature become thoroughly decomposed, the continuous preparation method of this fertilizer has been greatly shortened manufacturing cycle, reduce the floor space needed for compost fermentation, and then improve the production efficiency of fertilizer.It addition, the high temperature of the yeasting of 65 DEG C～80 DEG C and 120 DEG C～250 DEG C becomes thoroughly decomposed, environment can effectively kill the harmful levels of pathogens of residual, worm's ovum etc. in fertilizer, thus realizing the innoxious continuous production of fertilizer.
Accompanying drawing explanation
