Technical field
The present invention relates to the retrofit technique of the defatted rice bran dregs of rice.
Background technology
Rice bran can extract oil, and is rice bran oil, nutritious, and remaining is just rice bran meal, and rice bran meal is the byproduct producing rice bran oil by expansion extraction method.Product is identical with primary rice bran external form, but the primary rice bran of Performance Ratio is excellent, in warm process, improve the content of albumen, lipase is lost activity, and eliminating the undesirable substances such as the true mattress in rice bran, thin mattress, under normal storage conditions, rice bran meal raw material is deposited and is undergone no deterioration for 3 months.In yellow ~ yellowish-brown, there are meter taste or roasting fragrance, powdery.
Rice bran meal is the feedstuff of high-quality, can be directly used in home poultry raising, also can be used as feed addictive.Rice bran meal is rich in the materials such as higher protein, crude fibre, mineral matter, simultaneously containing the nutrient such as Cobastab, E and potassium, silicon, amino acid.
Summary of the invention
The object of the present invention is to provide a kind of retrofit technique of the defatted rice bran dregs of rice, raw material is done with the defatted rice bran dregs of rice, process the finished product of moisture < 6.0%, fineness degree GB 30 order all-pass, this finished product is mainly used as the carrier of feeding vitamin, additive agent for feeding, finished product of the present invention is dry with its moisture, rough porous, there is space pipeline inside, has stronger adsorptivity and load, can meet the characteristic of carrier preferably.
For achieving the above object, technical scheme of the present invention designs a kind of retrofit technique of the defatted rice bran dregs of rice, comprises the steps:
1) select the appropriate defatted rice bran dregs of rice and do raw material;
2) magnetic separation is carried out to raw material, remove the metal impurities in raw material;
3) being pulverized material by pulverizer, is powder by crushing material;
4) by insurance sieve, step 3) gained powder is screened, obtain the powder that fineness degree is up to standard, and the pulverizer that material below standard for the fineness degree filtered out drops in step 3) is pulverized again;
5) dried by the powder that drying unit is up to standard to step 4) gained fineness degree, in 80 DEG C of constant temperature dryings 5 minutes;
6) screen classification is carried out to the powder after oven dry;
7) powder after screen classification is cooled to room temperature;
8) carry out magnetic separation again to cooled powder, remove metal impurities further, obtain finished product, this finished product is mainly used as the carrier of feeding vitamin, additive agent for feeding.
Preferably, the insurance sieve in described step 4) is 30 order insurance sieves.
Preferably, in described step 5), drying unit is electrical heating screw propulsion auger drying unit, this electrical heating screw propulsion auger drying unit with screw propulsion auger for drying tunnel, at screw propulsion auger outer wall cover tubing, the built-in heat-conducting silicone grease of sleeve pipe, using heat-conducting silicone grease as conduction material, by heating tube, heat-conducting silicone grease is heated, and by heat-conducting silicone grease heating drying tunnel, step 4) gained fineness degree powder up to standard is uninterruptedly dried in drying tunnel, moisture is separated from powder, reaches moisture requirement.
Preferably, the auger in described electrical heating screw propulsion auger drying unit is paddle formula screw propulsion auger.
Preferably, the moisture < 12.5% of the described defatted rice bran dregs of rice, protein G reatT.GreaT.GT 15%, crude fibre < 12.0%, fatty < 2.0%, ash < 12.0%.
Advantage of the present invention and beneficial effect are: the retrofit technique providing a kind of defatted rice bran dregs of rice, raw material is done with the defatted rice bran dregs of rice, process the finished product of moisture < 6.0%, fineness degree GB 30 order all-pass, this finished product is mainly used as the carrier of feeding vitamin, additive agent for feeding, finished product of the present invention is dry with its moisture, rough porous, there are stronger adsorptivity and load, the characteristic of carrier can be met preferably.
The present invention carries out screen classification to the powder after oven dry, can reach following effect:
(1) prevent in process, having other materials to be mixed into, or process equipment there are the objects such as screw to come off.
(2) the powder fineness degree of drying changes, and guarantees the fineness degree of finished product through screen classification.
The present invention is optimized control to the moisture content of finished product (carrier), fineness degree.
1, moisture content
Because moisture plays the important function, particularly monomer vitamin ensureing product quality in feeding electrolytes and minerals carrier uses, if moisture is more than 6.0%, one-dimensional quality will change, and cannot ensure product quality.
The common oven dry of normal temperature is adopted to be to reach moisture < 6.0%, the present invention adopts 80 DEG C of constant temperature dryings 5 minutes, powder is uninterruptedly dried in the drying tunnel (screw propulsion auger) of drying unit, moisture is separated from powder, reaches moisture requirement.
2, fineness degree
Under normal circumstances, pulverizer powder is out that granular size is uneven, the present invention first extracts powder up to standard for fineness degree by increasing insurance sieve, the below standard material of fineness degree drops into pulverizer and again pulverizes, circulation is carried out, and guarantees that the fineness degree of manufactured goods (carrier) reaches the requirement of GB 30 order all-pass.GB 30 order is the normal fineness degree of feeding vitamin, in the same size with vitamin masterbatch pellet, can increase the uniformity of vitamin finished product.If do not reach GB 30 order all-pass, difference will be had with masterbatch pellet, easily produce classification phenomenon, have impact to quality stability, uniformity.
