Abstract
The invention discloses a coated puffed feed processing method. The coated puffed feed processing method comprises the steps that a glue solution is prepared, wherein glue powder and potassium chloride are added to each 100 ml of water, stirring and heating are conducted for 20-40 min at the temperature of 90-105 DEG C, and then the glue solution is obtained; feed pre-processing is conducted, wherein water soluble substances are dissolved in water, so that a water solution is prepared, and then the water solution is sprayed to the surface of the puffed feed; the fat-soluble vitamin is dissolved in grease, then the obtained solution is sprayed to the surface of the puffed feed so as to wrap the puffed feed, and thus a second coating layer is formed; the glue solution is pumped into a liquid storage tank of a high-pressure vacuum coating machine, is evenly stirred and then is sprayed to the surface of the pre-processed feed, and then the coated puffed feed is obtained. The method is simple, a perfect and bright flue film is formed on the surface of the puffed feed, the appearance is attractive, the stability of the feed is high when the feed is placed in water, losses of nutrient substances are reduced, active substances which are added at the later stage are well protected, stability of the quality of the feed is kept, the powder content of the feed is reduced, and the storage life of the feed is prolonged.
Description
Technical field
The present invention relates to a kind of feed processing technology field, particularly relate to a kind of processing method of coating expanded pellet diet.
Background technology
Traditional powdery compound feed and granular mixed feed also exist water stability difference, sinking speed is fast, easily cause the drawbacks such as the lost waste of feed and water pollution, be faced with stern challenge, and expanded pellet diet can overcome the drawback of powdery and hard pellet diet preferably.Research shows; the intrinsic feature of expanded feeds of aquaculture is well suited for the aquaculture of modernization and scale; thus very large range of application and application space will be had; although processing cost is higher than general hard pellet diet; but it can utilize more cheap raw material; reduce the consumption of adhesive, mould inhibitor, efficiency of feed utilization is higher, but simultaneously with HTHP to shortcomings such as nutriment destruction such as enzyme preparation, probiotics, vitamin, protein and amino acid.
Expanding processing is a feed manufacturing new technology, feed is the expanded process being actually a high-temperature instantaneous in extrusion chamber: mixture is in the environment of high temperature, high pressure and high shear force, high-moisture, by mixed, modified, pressure build up continuously, slaking, extrudes nib and suddenly forms a kind of feed of bulk porous after step-down.Puffing process is very big to active material destructiveness in raw material, current bulking process adds some liposoluble vitamins when only spraying grease rearward, and address only the rear interpolation of liposoluble substance, shortcoming is that aquatic livestock eats for a long time, can nutritional imbalance be caused, cause pathology; And cause breeding water body grease severe contamination, make aquatic animal generation disease or death.And the various active materials spraying interpolation are rearward only stick to feed granules surface, easily in dissolving water body in the process of throwing something and feeding, cause the loss of feed actives; Reactive substance adheres is more easily subject to the impact of illumination, oxidation on surface, and causes loss larger between the storage life.At present the disclosed patent major part about expanded pellet diet be for certain fish resisting stress, raise together with, the expanded pellet diet such as fatty liver, Malpigmentation and preparation method thereof, up to now, the research for expanded pellet diet trypsin method key technology process aspect is not also had.

3.
The coating expanded pellet diet that the method using following detection method to detect use embodiment 3 obtains:
1, rate of body weight gain
Common expanded pellet diet is immersed in water, can water suction weightening finish to constant weight, then slowly alleviate because particulate matter progressively scatters and disappears rapidly.And the expanded pellet diet being coated with membrane material is immersed in water, diaphragm can produce certain impact to the water suction weightening finish of feed.By diaphragm, feed granules absorption speed is slowed down, particulate matter phenomenon of scattering and disappearing is controlled, and therefore, by the rate of body weight gain change of feed granules, the present invention judges whether colloidal substance meets the trypsin method requirement of bulking process.
As shown in Figure 1, after 40min, rate of body weight gain tends towards stability, and the expanded pellet diet water stability being coated with membrane material is good.
2, iron content
The object of expanded pellet diet spraying coating liquid is the molten mistake in order to prevent rear interpolation nutriment.The present invention, to measure the dissolution rate of a certain material when feed is immersed in water, verifies the effect of coating.Due to Fe
2+ion has good penetrating power, so select Fe
2+the dissolution rate of ion is as the index judging coating effect.Because in feed, iron content is lower, but we are by artificial rear addition manner, it is sprayed into expanded pellet diet surface together with other nutriment, thus increases iron content in feed, then utilize the stripping quantity of Their Determination by Spectrophotometry iron.
Expanded pellet diet surface uniform being coated with ferric ion solutions dries rear equivalent grouping, and A group does not spray coating liquid feed, the spraying coating liquid feed that B group is obtained by embodiment 3.60 A group feeds and 60 B group feeds are equally divided into three groups separately, put into three 250ml beakers respectively, respectively add 50ml distilled water, soak after 3 hours, take out feed, detect iron content in solution by the absorption photometric determination method of content of trace iron.
Iron content in table 1 solution
The feed iron stripping quantity not spraying coating liquid is 3 ~ 4 times of spraying coating liquid feed, therefore can illustrate, the stripping of iron when coating can prevent feed to be immersed in water well, namely coating liquid well can reduce the molten mistake of nutriment at the glued membrane that feed surface is formed.
Result of use experiment is as follows:
Select 200 neat specifications, the grass carp that physique is healthy and strong, age in days is identical is as subjects, be divided into test group and control group, often organize 100, put into water quality respectively, fishpond that breeding environment is identical feeds, test group feeds the spraying coating liquid feed obtained by embodiment 3, control group feeds common grass carp expanded pellet diet, two kinds of number of times that feed intake, charging time, the quantity that feeds intake is all identical, and test period is 2 months.After 2 months, result is as following table:
| Group | Equal initial weight (g) | Equal end heavy (g) | Average daily gain (g/ tail) | Survival rate (%) | The incidence of disease (%) |
| Control group | 138.64 | 305.36 | 7.4 | 89% | 16% |
| Test group | 138.92 | 401.08 | 9.0 | 100% | 3% |
Weigh through finally statistics, the average daily gain of control group grass carp is 7.4g/ tail, and the average daily gain of test group grass carp is 8.9g/ tail, and test group grass carp daily gain is apparently higher than control group grass carp daily gain.The grass carp premunition of forage feed of the present invention is strong, and the incidence of disease of test group grass carp is lower than control group 13%.Compared with control group, test group grass carp physique is healthy and strong, and premunition is strong, and survival rate is improved greatly, fish body grossness, and Fresh & Tender in Texture, fish body color is more beautiful.
