Description
Technical field
The present invention relates to a kind of piglet puffed rice and its production methods, belong to technical field of agricultural product process.
Background technology
Rice is paddy manufactured finished product after the processes such as cleaning, husking, husk rice, finished product arrangement.Carbon containing aquation in rice
Object 75% or so, protein 7%-8%, fatty 1.3%-1.8% are closed, in addition, also contain abundant vitamin B1 and inorganic salts,
Such as calcium, phosphorus, iron.Carbohydrate in rice is mainly starch, the protein in rice mainly by albumin, globulin,
Four kinds of protein compositions such as protein,alcohol-soluble and glutelin, the biological value of protein and the composition of amino acid are all than small
The cereal crops such as wheat, barley, millet, corn are high, digestibility 66.8%-83.1%.Rice protein is acknowledged as high-quality protein,
The amino acid Compositional balance of mainly rice protein is reasonable, and nutritive value is high, meets the idealized model of WHO/FAO recommendations, wherein
Methionine content is higher, be other vegetable proteins it is incomparable, can compare favourably with egg, cow's milk, be other vegetable proteins
It is incomparable, in addition, rice protein also has the healthcare functions such as anti-diabetic, anti-cholesterol.
Although rice protein is ideal vegetable protein, there is many excellent specific properties, rice to be widely used in
In young animal feed, but since rice is not further processed, palatability, digestibility are not fine, young age
It is non-digestible to lead to diarrhea after animal especially piglet feeding.Currently, having there is some patent reports to be added in feed
Expanded rice flour, but the gelatinization degree of its starch need to be improved.
Invention content
The purpose of the present invention is to provide a kind of piglet puffed rice and its production method with high gelatinization degree, with solution
Certainly the low puffed rice of gelatinization degree is not easy to be digested and assimilated the problem of leading to diarrhea by piglet.
To solve the above-mentioned problems, technical solution used by the production method of piglet puffed rice of the invention is such as
Under:
A kind of production method of piglet puffed rice, includes the following steps:
1) feeding:By rice raw material be sent into puffing machine inlet and enter Builking cavity in, the rice raw material it is aqueous
Rate is 8%~12%;
2) puffing:Rice raw material is promoted by screw rod in Builking cavity, squeezes, heats up, later from the mould of bulking machine discharge port
It is extruded in hole, forms initial puffed rice, the Builking cavity front-end temperature is 105~110 DEG C, and stage casing temperature is 110~120
DEG C, back segment temperature is 120~130 DEG C;
3) cooling and crushing:Will initial puffed rice cooling after pulverize and sieve to get.
The rice that some are contained with impurity needs to first pass through sieve and rolling magnetic bucket removes sundries therein and iron class is miscellaneous
Matter, later could be as the rice raw material of the present invention.The rice raw material is preferably that hardness is strong, transparency is good, cracks rice less, abdomen
White small, the bright rice of color and luster.
In order to improve expansion effect and puffing efficiency, the grain size for controlling rice raw material, the grain of the rice raw material are needed
Diameter is preferably 2.5mm~3.5mm.
The feeding is rice raw material to be sent into Builking cavity feed inlet, and enter the process of Builking cavity.The feeding
Can be the feed inlet for manually rice being delivered to Builking cavity, or mechanical transmission is delivered to rice the charging of Builking cavity
Mouthful.In order to improve efficiency, it is preferable to use mechanical transmission replaces that rice is manually delivered to Builking cavity feed inlet.Further preferably
To use auger that rice is delivered to the feed inlet of Builking cavity.
The rice raw material that is puffed to is promoted by screw rod in Builking cavity, squeezes, heats up, and discharges later from bulking machine
It is extruded in die hole, forms the process of initial puffed rice.Specially rice raw material enters in Builking cavity, in being advanced over for screw rod
Cheng Zhong, rice raw material are gradually extruded into the rear end of Builking cavity from the leading portion of Builking cavity, and since compression generates heat, Builking cavity is opened
Begin to heat up, Builking cavity front-end temperature is 105~110 DEG C, and stage casing temperature is 110~120 DEG C, and back segment temperature is 120~130 DEG C.
Puffing cavity rear end come out " rice " have higher temperature (it is essentially identical with the temperature of puffing cavity rear end, about 120~
130 DEG C) and pressure, the moisture contained in rice forms the vapor of high temperature and pressure, and rice is extruded the moment of discharge port, and water steams
Gas encounters normal temperature and pressure, and flash evapn, inside rice and surface forms loose and porous structure, that is, forms initial puffed rice,
The initial puffed rice is the rice directly from bulking machine discharge port output, since bulking machine is quantity-produced equipment,
" puffed rice " temperature at this time is higher, and volume is larger, and length is longer, is not easy to packaging, storage, carries out cooling, crushes
Etc. processes.
Single serew bulker may be used in the bulking machine, can also use twin-screw Bulking Machine, as long as can meet swollen
Change the temperature of three sections of chamber, is preferably single serew bulker in the present invention, the rotating speed of screw rod is 450~550r/min.
In order to control the size of puffed rice, it is convenient for subsequent packing and packaging, the diameter of the discharging mouth die hole excellent
It is selected as 8~12mm, the diameter of the initial puffed rice formed at this time is also 8~12mm.
The purpose of the cooling is that the temperature of initial puffed rice is reduced to room temperature.Preferably use chilling roll cold
But, cylindrical outer is preferably connected with cooling cyclone.The crushing is that initial puffed rice after cooling is crushed to grain
Diameter is the process of 0.8~1.2mm.
For the ease of storing and transporting, the puffed rice after cooling, crushing can also be packed and be dispensed, it is described
It is packaged as puffed rice being encased in sack or box.The sack can be polybag, can be woven bag, preferably
It is bag weaved for the chemical fibre with plastic inner lining, it can be used for after encapsulation moisture-proof.The box can be paper box, can be metal
Box etc..The weight of the packaging can be 5kg, 10kg, 25kg, 40kg etc., according to actual conditions, preferably 40kg.
Technical program of the present invention also lies in a kind of piglet puffed rices produced using the above method.
The present invention by rice raw grain carry out extrusion processing technology, it is puffing after rice microstructure disordering,
Volume becomes larger, and is conducive to water soluble ingredient dissolution, is conducive to the effect of enzyme;Starch degradation simultaneously, obtains higher gelatinized starch;
Protein cleavage is amino acid, is conducive to absorb, and the palatability and digestic property of final rice are all improved, and feedstuff is used as
It is added in young animal feed, feeding one month, the diarrhea situation of piglet is obviously improved.
