Problems solved by technology

Although the total amount of feed protein in the world exceeds 2.5 million tons, it is far from meeting the requirements of the development of animal husbandry. Therefore, the development of new bacterial feed has broad prospects for development.

Embodiment 1

[0042] Adopt the following method to manufacture the high-protein feed with orange peel as raw material:

[0043] 1) Mixing: Grind citrus peel and wheat bran with a pulverizer, then mix orange peel residue, wheat bran and urea at a mass ratio of 100:20:1, pass through a 40-mesh sieve, and take the sieved material and mix it well. The fermentation substrate, wherein the orange peel is the orange peel that has not been dehydrated after the citrus industry squeezes the juice;

[0044] 2) One-stage fermentation: inoculate the fermented substrate prepared in step 1) with a fermentation broth at a mass ratio of 10:3 to form a one-stage fermentation material with a moisture content of 65.41%, and ferment it at 40°C for 72 hours to produce one-stage fermentation Fermented feed; stir the above-mentioned fermented material once every 8 hours, and stir for 25 minutes each time to ensure sufficient oxygen in contact with it; the solute of the fermented bacteria liquid used is Aspergillus ...

Embodiment 2

[0047] Adopt the following method to manufacture the high-protein feed with orange peel as raw material:

[0048] 1) Mixing: Grind citrus peel and wheat bran with a pulverizer, then mix orange peel residue, wheat bran and urea at a mass ratio of 105:21.20:1.05, pass through a 35-mesh sieve, and take the under-sieve material and mix it well. The fermentation substrate, wherein the orange peel is the orange peel that has not been dehydrated after the citrus industry squeezes the juice;

[0049] 2) One-stage fermentation: inoculate the fermented medium prepared in step 1) with a fermentation broth at a mass ratio of 10:3.52 to form a one-stage fermentation material with a moisture content of 67.80%, and ferment it at 38°C for 70 hours to produce one-stage fermentation Fermented feed; Stir the above-mentioned fermented material once every 8 hours, and stir for 23 minutes each time to ensure sufficient oxygen in contact with it; the solute of the fermented bacteria liquid used is A...

Embodiment 3

[0052] Adopt the following method to manufacture the high-protein feed with orange peel as raw material:

Abstract

The present invention provides a high protein feed producing method using orange peel residues as raw materials and a feed. The production method is as follows: a fermentation substrate is inoculated with first fermented bacteria liquid to conduct the primary fermentation, and then the fermented materials are inoculated with second fermented bacteria liquid to conduct the secondary fermentation to obtain the high protein feed. The fermentation substrate includes orange peels, wheat bran and urea. The first fermented bacteria liquid includes aspergillus oryzae and trichoderma koningii; the second fermented bacteria liquid includes candida tropicalis and torulopsis utilis. Both the primary and secondary fermentation are aerobic fermentation. The function of the primary fermentation is to remove the substances of pectin, cellulose and hemicellulose from the orange peel; the main function of the secondary fermentation is to increase the protein content and obtain the high protein feed. The feed obtained after two stages of fermentation is high in protein content and good in palatability, is easy to be absorbed and utilized by animals, has a long shelf life, and is an excellent animal feed. The process is simple; the cost is low; and the producing method and the feed are suitable for large-scale promotion and utilization.

Description

technical field [0001] The invention belongs to the technical field of feed production and the technical field of solid waste recycling, and in particular relates to a production method and feed of high-protein feed using orange peel as raw material. Background technique [0002] China's annual output of citrus ranks first in the world. Many orange juice production plants have been established in Chongqing and other places. However, about 60% of orange peel residue will be produced after citrus juice is squeezed. Comprehensive utilization, so it is basically treated as waste, resulting in a large accumulation of leather dregs. This is not only a great waste of effective resources, but also causes great pollution to the environment and affects the ecological balance. [0003] Orange peel is rich in nutrients such as carbohydrates, fats, vitamins, amino acids and minerals, and the medicinal ingredients in it can also inhibit Staphylococcus, catarrhena, Haemophilus and other...
