Embodiment 1

[0052]100kg of feather meal was removed, pulverized, and 15kg of clean water was added to make it evenly tempered, and then high-pressure steam was introduced. Under the conditions of cooking temperature of 150°C and cooking pressure of 400KPa, the cooking time was 2 hours, and 121kg of cooked feather meal wet basis was obtained. (High pressure steam increases moisture 6kg).

[0053] Add 500kg of clean water to 121kg of steamed feather meal wet base to prepare 621kg of feather meal slurry; use 20% sodium hydroxide solution to adjust the pH to 8.6-8.8, add 2.5kg of keratinase, and enzymatically hydrolyze at 50°C Next, liquid enzymatic hydrolysis for 5 hours to obtain 622kg feather powder enzymatic hydrolysis slurry.

[0054] Using plate and frame extrusion, 622kg of feather meal enzymatic hydrolysis slurry was separated from solid and liquid to obtain 577kg of feather meal enzymatic hydrolysis diluent and 45kg of feather meal enzymatic hydrolysis slag wet base; Obtain 110kg fe...

Embodiment 2

[0058] 500kg of feather meal was removed, pulverized, tempered and tempered with 50kg of clean water, and then high-pressure steam was introduced. Under the condition of cooking temperature of 160°C and cooking pressure of 500KPa, the cooking time was 2h, and 570kg of cooked feather meal wet basis was obtained. (High pressure steam increases moisture by 20kg).

[0059] Add 2530kg of clean water to 570kg of steamed feather powder wet base to prepare 3100kg of feather powder slurry; use 20% sodium hydroxide solution to adjust the pH to 8.6-8.8, add 15kg of keratinase, and enzymatically hydrolyze at 60°C , liquid enzymatic hydrolysis for 4 hours, and 3113kg of feather meal was enzymatically hydrolyzed.

[0060] Using plate and frame extrusion, 3113kg of feather powder enzymatic hydrolysis slurry was separated from solid and liquid to obtain 2888kg feather powder enzymatic hydrolysis liquid and 225kg feather powder enzymatic hydrolysis slag wet base; then using evaporation equipme...

Embodiment 3

[0064] 1000kg of feather powder is removed from impurities, crushed, and 80kg of clean water is added to make it evenly tempered, and then high-pressure steam is introduced. Under the conditions of cooking temperature of 150°C and cooking pressure of 400KPa, the cooking time is 1.5h, and 1110kg of cooked feather powder is obtained. Base (high pressure steam increases moisture 30kg).

[0065] Add 6000kg of clean water to 1110kg of steamed feather powder wet base to prepare 7100kg of feather powder slurry; use 20% sodium hydroxide solution to adjust the pH to 8.6-8.8, add 27kg of keratinase, and enzymatically hydrolyze at 60°C , liquid enzymatic hydrolysis for 4 hours, and 7120kg feather powder enzymatic hydrolysis slurry was obtained.

[0066] 7120kg of enzymatic hydrolysis of feather powder is separated from solid and liquid by plate and frame extrusion to obtain 6670kg of enzymatic hydrolysis of feather powder and 450kg of wet base of enzymatic hydrolysis residue of feather p...

Abstract

The invention belongs to the technical field of feed, enzyme preparations and microorganisms and particularly relates to a preparation method of functional glycolysis feather meal feed. The preparation method comprises the following steps: removing impurities in feather meal, crushing, adding water for tempering, and carrying out high temperature cooking to obtain cooked feather meal; then addingwater and keratinase and carrying out temperature and time-controlled liquid enzymolysis to obtain feather meal enzymolysis pulp; carrying out solid-liquid separation and concentrating to obtain a feather meal enzymolysis concentrated solution and a feather meal enzymolysis residue wet base; carrying out mixed fermentation on the feather meal enzymolysis residue wet base, protein feed and a composite strain solution to obtain fermented feather meal residues; and mixing the feather meal enzymolysis concentrated solution with the fermented feather meal residues and drying to obtain the functional glycolysis feather meal feed. The functional glycolysis feather meal feed prepared by the preparation method disclosed by the invention is rich in nutrients such as oligopeptide, amino acid, lacticacid, oligosaccharide, probiotics and the like and has the characteristics of high protein, easiness in digestion, high palatability, low content of antinutritional factors, synergistic nutrition of enzymolysis feather meal and fermented soybean meal and the like.

Description

technical field [0001] The invention belongs to the technical fields of feed, enzyme preparations and microorganisms, and in particular relates to a preparation method of functional fermented feather meal feed. Background technique [0002] China is a country with a large population and the largest pig raising country in the world. In 2017, the output value of China's animal husbandry industry reached 3.6 trillion yuan, the output of pork, beef, mutton and poultry reached 84.31 million tons, 689 million live pigs were slaughtered, of which 42 million sows were on hand, and the output of pork was 54.87 million tons. According to statistics from the Ministry of Agriculture, the national commercial feed production reached 205 million tons in 2017. Among them, 179 million tons of full-price feed, 21.51 million tons of concentrated feed, 6.9 million tons of premixed feed, including 89.74 million tons of pig feed, 90 million tons of poultry feed, 53 million tons of aquatic feed, ...
