Description
Technical field
The present invention relates to feedstuff industry, particularly relate to animal and fowl fodder processing technology and process equipment.
Background technology
The current processing technology of animal and fowl fodder has a variety of, and common processing technology mainly contains " traditional livestock and poultry material processing technology " and " livestock and poultry material expansion processing technology ", but these common processing technologys all exist some problems.
1. traditional livestock and poultry material processing technology
Traditional livestock and poultry material processing technology is, material through pulverizing, then mixes, more modified, then granulates, then cools, and finally packing obtains finished product.
In such technique, the slaking workshop section of material depends on modified and granulation workshop section.In order to obtain the livestock and poultry material of high slaking, need to use the modified of higher temperature.On the one hand, the amplitude being improved material gelatinization degree by quality-adjusting device is not high, and gelatinization degree can not higher than 30%; On the other hand, if quality-adjusting device temperature is too high, in material, also can bring too much moisture, cause modified after material occur when granulating the phenomenon of skidding between pressure roller and material directly causing breaks in production.
In this technique, a problem of most critical is, modified use high temperature, causes the loss of heat-sensitive ingredients in feed excessive, affects the culture efficiency that feed is final.This technique is close to and is eliminated at present.
2. livestock and poultry material expansion processing technology
In order to improve the amount of cure of feed, be conducive to digesting and assimilating of livestock and poultry animal.Also some users are had to use " livestock and poultry material expansion processing technology " at present.This technique, compared with " traditional livestock and poultry material processing technology " before, adds expansion workshop section between modified and granulation workshop section.
Livestock and poultry material expansion processing technology is, material through pulverizing, then mixes, more modified, in expansion, then granulates, then cools, and finally packing obtains finished product.
The object that expansion workshop section increases is the amount of cure of improving material, and due to the effect of bloating plant, the gelatinization degree of material can reach 40-45%.But its shortcoming also exists and can not solve always.
1) gelatinization degree of material is restricted:
The gelatinization degree of material is the highest can only reach 40-45%, wants to promote gelatinization degree further again, and as gelatinization degree is wanted to rise to 50-60%, this technique just can not meet.
2) the heat-sensitive ingredients loss in feed is large
" livestock and poultry material expansion processing technology " compared with " traditional livestock and poultry material processing technology ", because only emphasis considers the amount of cure increasing material, modified, to expand and in the process of granulating, the loss of heat-sensitive ingredients can be larger.This point directly causes feed product culture efficiency not reach expected effect.
3) pellet is hard, and the melt water time is long
Because expansion process amount of cure is 40-45%, the material in such a slaking interval, after granulating, the hardness of finished granule can be very high.We can detect the hardness number of particle by the melt water time, and such particle melt water time is general all more than 1 minute, and some feed melt water time even reaches more than 3-5 minute.
The melt water time of feed is long, just equals pellet too hard, in the process of feeding, grazing rate can be caused to reduce.When some sucking pigs have grit, sucking pig oral cavity can be caused damaged, directly cause the death rate of sucking pig to promote.
4) feed is little in bubbly water water volume
The soaked volume of feed is also the important indicator weighing feed quality.Feed is large at the volume of bubbly water water, and what represent that feed can reach digests and assimilates.And the expanding volume of feed in water of expansion process processing is smaller, get 50g finished feed, the volume soaked in water is only only 170ml, and good feed can about 250ml.
