Abstract
The present invention is a kind of method of utilizing straw and other processing feedstuff with stalks of crops.It is with the material that the crushes custom-designed a kind of high-pressure bottle (being the physics converter) of packing into, feeds steam simultaneously and impel crude fibre in the material and lignin to take place to transform to make feed under the HTHP effect.The present invention has advantages such as raw material sources are wide, and technical process is simple, and nutrient content height and production cost are low, and is easy to implement to promote.
Description
The invention belongs to feed production method, particularly utilize the method for various crop straw manufacturing feeds such as straw.
Feed is the most important condition of development aquaculture.Common both at home and abroad feed majority be base stock preparation production with grain (comprising coarse food grain and smart grain), and its cost height, benefit are low, are unfavorable for the development of aquaculture.
Straw and other crop straw are potential feed resources.But because their crude fibre and content of lignin height, nutrition content such as protein and digestible sugar, enzyme are low, thereby can not be directly edible for the simple stomach livestock and poultry as feed.Japan once adopted method for hydrolysis that crop straw is carried out immersion treatment in the world, but part lignin and crude fibre are softened, and can not have additional nutrients.Also there is similar problem in a kind of saccharified pig feed that domestic sixties end, early seventies occur.Be that a large amount of crude fibres can not get transforming, thereby can not have additional nutrients, extensively do not promote so far.Also have a kind of expanded method that occurs in recent years, also just merely that the crop straw of pulverizing is expanded, make it soft, do not touch intracellular molecular structure, composition can not have additional nutrients.
The object of the present invention is to provide a kind of crop straw cellular elements internal structure of pulverizing of impelling to change, a large amount of crude fibres, lignin conversion are the method for nutritions such as sugar and crude protein, fundamentally solve the problem that people and animals strive grain.
Above-mentioned purpose realizes in the following manner:
Design a high-pressure bottle as the physics converter, dry rice straw or other crop straw are pulverized the back water mix wetly, the converter of packing into feeds steam simultaneously.When the air pressure in the converter during apparently higher than an air pressure, open drain tap and get rid of cold air in the converter, valve-off continues to feed steam then.When air pressure rises to certain altitude, utilize safety valve control and stablize air pressure, keep transforming 20～40 minutes, then with the discharging opening valve open, allow material is expanded naturally to come out, contain sugared more feed.In order to improve Protein content, can be for further processing to the expanded material that comes out, way is: when treating that material is cooled to 50 ℃ of left and right sides, it is broken into the good place that piles up ventilation condition greatly utilize the air inoculated and cultured promptly to get about 7 days to contain the feed of crude protein more than 10%.
The invention provides following most preferred embodiment, for reference fully:
The physics converter is designed to Cylinder (2 meters of diameters, are made of the bloom that 3mm is thick by long 3 meters).One end on top is installed charging aperture and inlet valve, and the other end is installed air bleeding valve and safety valve.Thermometer and air gauge are installed in the centre on top.It is expanded valve that the end that cross-peen and charging aperture distance are far away is installed discharging opening, during production, admixes 20% clear water in the material that crushes, the converter of packing into then.Open inlet valve simultaneously and feed steam, when air pressure rises to 1.5kg/cm
2The time, utilize safety valve control and stablize air pressure, keep transforming 40 minutes, open the valve of discharging opening again.Allow material is expanded naturally to come out, the raft that breaks into during to 50 ℃ about a cubic metre to be cooled is cultivated in the ventilation and to be got final product about 7 days (3 days autumns).Need commercialization in enormous quantities to produce, it can be dried (, should change dusting cover and carry out the pulverizing second time) if pulverize slightlyer before transforming.
Advantage of the present invention: 1, raw material sources are wide; 2, production equipment and technology are simple; 3, transform fully, good palatability is of high nutritive value; 4, production cost is low, and high efficiency is conducive to implement and promote.
