Abstract
The present invention is fast crop stalk ammoniating process with liquid ammonia for producing feed. The production process includes loading crushed or squashed into high pressure container, filling the tank with liquid nitrogen, applying high pressure to convert coarse fiber in stalk in short time and combining with protein nitrogen to produce ammoniated feed. The said process is simple, can well maintain the nutritious matters in stalk and raise coarse protein content and has short processing time, high production efficiency, low cost, high processing effect, reuse of recovered liquid ammonia, no pollution and other advantages.
Description
The invention belongs to the roughage processing method, thereby particularly utilize agricultural crop straw to carry out the method that quick ammonification increases substantially its nutritive value.
The fast development that Developing of Animal Industry, particularly ruminant are cultured needs a large amount of roughages, and forage grass resource can not satisfy its development need far away.Utilizing crop by-product such as stalk is to solve the desirable approach that ruminant forage grass lacks.
The ammonification of stalk is handled research and is started from the forties in 20th century, up to the later stage seventies just the various roughages of diversion treatments to improve on its Nutritive Value.The principle of ammonification is: when stalk and ammonia are done the time spent, organic substance in the stalk and ammonia generation ammonolysis reaction, destroy the ester bond between lignin and cellulose, hemicellulose, destroy the mosaic texture of plant cell wall lignified fiber, stalk is expanded, the phenolic acid material reduces, and stimulates the effect such as quantity increase of adhering to of cud cellulose-decomposing bacteria, helps improving coarse-fibred degraded in the stalk.The ammonium salt that forms in the ammonifying process can be used as growth, the breeding that nitrogenous source promotes rumen microorganism.On the other hand, the ammonium hydroxide of ammonia water-soluble back formation has alkalinization to roughage.Therefore, straw ammoniation can improve the nutritive value of low-quality roughage by the double action of alkalization and ammonification.Ammonification facture raw material commonly used has four kinds of liquefied ammonia, ammoniacal liquor, urea and ammonium hydrogencarbonates.The tradition ammonating process time is long, efficient is low, and used ammonia source can not be reclaimed and be caused waste, can not satisfy large-scale production.This technology is to utilize liquefied ammonia under high pressure conditions stalk to be carried out fast processing and realize that liquefied ammonia reclaims to cut the waste, and shortens the processing cycle greatly, increases substantially straw nutrition and is worth, and the stalk after the processing is used for ruminant raises, and becomes desirable roughage.
The present invention is that a kind of liquefied ammonia that utilizes carries out the method that feed is produced in quick ammonification to agricultural crop straw under high pressure conditions.Raw material sources are extensive, and technical process is simple, and stalk nutritive value after this method is handled increases substantially, thick protein improves 1～2 times, be very suitable for ruminant and raise, the processing time shortens more than 30 times than traditional approach, has production efficiency height, low, the high treating effect of cost.This method is easy to implement to promote, can fundamentally solve the difficulty of roughage shortage and make a large amount of discarded stalks obtain better utilization.
This method realizes in the following manner:
It is with in stalk (rubbing broken or flattening) the custom-designed a kind of high pressure sealing container of packing into (being the fast stalk ammonating process tank), the vavuum pump state that is evacuated will be utilized in the jar, inject liquid ammonia, under the high pressure effect, (be no more than 1 hour) at short notice the crude fibre in the stalk is transformed, and make ammoniated forage in conjunction with nonprotein nitrogen.
According to design of this method proposition system and technological process;

Four, operating process
1,6. 1. ammonia storage tank is added liquefied ammonia to the maximum storage capacity of ammonia storage tank by the ammonification station.
2, the pre-treatment of stalk
Choose stalk, water content is lower than 20%, and maize straw can be rubbed and be broken into 2～3cm segment as handling raw material.The mode that rice straw can be taked to flatten is handled.
3, raw material adds dress
Raw material add the dress before all valves of maintenance system (except that liquid level gauge) be in closed condition.Open 3. mouth of process tank, take out liner sieve basket, the stalk of packing into, compacting.Charge weight is lower than sieve basket upper edge 10cm.With the liner sieve basket process tank of packing into.
4, process tank sealing
Close the process tank mouth, adopt the fixed screw symmetry fixedly to tighten.
5, vacuumize
Open the bleeding point valve, start vavuum pump and 4. process tank is vacuumized.
6, annotate ammonia
Close bleeding point, keep the process tank vacuum; Close vavuum pump; Start ammonia pump 2., open and annotate ammonia system valve injection liquefied ammonia, note observing liquid level gauge position and Pressure gauge.Liquefied ammonia is annotated to the complete submergence of stalk, close ammonia pump 2., annotate the ammonia valve door, pick up counting.
7, ammonification
Different stalks adopt the different ammonification times.Note observing each Pressure gauge and liquid level gauge.
8, liquefied ammonia reclaims
After reaching the processing time, open the return liquid system valve, start ammonia pump 2. with liquefied ammonia from process tank 3. draw back fully to ammonia storage tank 1..Close ammonia pump 2., close the liquid outlet valve.
9, surplus ammonia reclaims
