Description
Technical field
The present invention relates to regulate a kind of method of feed moisture content, more particularly, the invention relates to the method for regulating the mash feed moisture content.
Background technology
Press the classification of feed outward appearance, can be divided into granulated meal and mash feed.The moisture content of mash feed is determined by the ratio that raw material self moisture content and raw material occupy in prescription.In production practices, because raw material self, the mash feed moisture content of producing in the time of many is lower, generally is lower than national standard.Cross two problems of mash feed ubiquity of low-water-content, the one, the higher kind of mash feed, particularly crude fiber content of low-water-content, bring difficulty can for follow-up granulating process, regular meeting the ring mould occurs and blocks or the granular fodder coking, so that can't produce; The 2nd, the mash feed of low-water-content be prone to dust from flying, contaminated environment, harm workers ' health.How to press both provisioning requests, regulate the moisture content of mash feed easily and effectively, be the difficult problem of production of fodder process always.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of specific water-in-oil emulsion of weight ratio preparation by feed is provided, emulsion is ejected into the method for mixing with mash feed in the mixer.Use this method, can effectively regulate the moisture content of mash feed, and can the long period store can not produce and go mouldy.
The present invention is achieved by following technical proposals: by production of fodder weight, calculate the consumption of water, oil, mould inhibitor, according to the usefulness oil mass that calculates and season, temperature, calculate emulsifying agent, antioxidant consumption again, above composition is mixed with mixed liquor, mixed liquor is carried out homogeneous to be handled, after fully emulsified, store through pans, again through the spraying machine metered injection, be ejected in the mixer and fully mix with mash feed by setting requirements, the adjusting mash feed reaches both moisture content of provisioning request.
As previously mentioned, emulsion of the present invention is made up of water, oil, emulsifying agent etc., and the effect of each constituent and consumption division are as follows:
One, water: take the running water or the phreatic water that meet the production of fodder standard, the purpose that adds water is the water content of regulating in the mash feed.Addition is to wish to obtain the poor of moisture content and actual material water ratio, multiply by the long-pending of mash feed weight and determines.
Be water addition=mash feed weight * (hope obtains moisture content-actual feed moisture content)
Two, oil: get all kinds of fluid oils that meet the production of fodder standard such as rape oil, soya-bean oil, corn oil, rice bran oil, fish oil.The purpose of refueling is under the effect of emulsifying agent, and the stir mixing water violent by machinery forms stable emulsion together.In this emulsion, water exists with microgranular, and oil promptly forms the Water-In-Oil particulate with the membranaceous water particle skin that is wrapped in.Because oil film exists shipwreck is directly contacted with air and feed to be free state, thereby reduced the activity of water, make moisture content can be in feed the preservation of long period, avoided simultaneously because water directly contacts caused various biology, chemistry, the physical process that is unfavorable for feed quality with feed.The addition of oil is the 1%-5% of mash feed weight, general pig concentrate feed, and the fryer complete diet pellet is 1%-4%.
Three, emulsifying agent: choose the HLB value that meets the edible sanitary standard and be lower than 9 emulsifying agent, generally the emulsifying agent that uses is food grade sucrose fatty ester or polyglycereol ricinoleate ester or monoglycceride.Its consumption is the 0.25%-1.0% of oily consumption, and its preferable amount is the 0.5%-0.8% of oily consumption.
Four, mould inhibitor: choose meet all kinds of mould inhibitors that national production of fodder uses standard all can, as propionic acid or propionate or fumaric acid two formicesters.The existence of mould inhibitor can suppress the growth of little life in the emulsion, simultaneously because the effect of oil film parcel makes the rate of release of mould inhibitor slow.The addition of mould inhibitor on deciding in season and area, can add or not add in the winter time or under the dry condition less, and can take the circumstances into consideration by the 0.001%-0.005% of feed weight to add summer, and spring and autumn or intermittent drizzles in the rainy season can add by 0.05%-0.2% season.The general choosing of the northern area of China is by the numerical value of lower limit, and the southern area choosing is by the numerical value of the upper limit.
Five, antioxidant: antioxidant can delay or stop composition the going bad when storage or use of institute's oil-containing in the mash feed, the selected antioxidant of this law invention is oily tea polyphenol preparation or oily ethoxyquin preparation, its consumption is decided on the temperature situation, at weather more than 30 ℃, can select for use by the 0.05%-0.2% of oil mass, at the weather below 30 ℃, the holding time is not long, can not add.
Choose a certain proportion of water, oil, emulsifying agent, mould inhibitor, antioxidant as stated above according to weather, season, area, respectively by five measuring pumps deliver to homogenize in the homogenizer handle make water in oil emulsion after, send pans to store, be ejected in the mixer through quantitative spray machine again and fully mix, can reach the purpose of regulating the mash feed moisture content with mash feed.
