Problems solved by technology

There are two problems in this treatment method: (1) it needs to consume certain resources; (2) the drying process will lead to the loss of some nutrients such as vitamins
Although the above-mentioned invention patents all use fermentation methods to process pomace and other materials to prepare feed, the preparation process is complicated, and the investment and production costs are high. It is difficult to implement industrial production for the production of feed protein, a product with low added value.

Embodiment 1

[0019] ① Strain propagation process: Lactobacillus acidophilus freeze-dried powder → A activation → B cultivation → C liquid cultivation → D inoculation expansion cultivation → E cultivation completion → F strain. Among them, the freeze-dried powder of Lactobacillus acidophilus was purchased from China Industrial Microorganism Culture Collection Management Center, and the preservation number is CICC6074.

[0020] A. activation

[0021] Wipe the seed tube with absorbent cotton dipped in 75% alcohol, then heat the top of the seed tube on a flame, and avoid direct heating of the bacteria or overheating. Drop sterile water onto the top of the heated inoculation tube to crack the glass, and knock off the top of the cracked inoculation tube with a file or tweezers. Use a sterile pipette to draw 0.3-0.4mL MRS liquid medium, drop it into the strain tube, and shake gently to dissolve the freeze-dried bacteria into a suspended liquid. Take about 0.2mL of bacterial suspension, transfer...

Embodiment 2

[0031] On the basis of Example 1, dry fermented pomace feed was prepared. The wet pomace fermented feed is fed through the scraper conveyor belt, and the impurities are removed again. The wet pomace fermented feed is transported into the mixer through the conveying auger, and the wet pomace fermented feed is evenly dispersed to avoid the state of agglomeration or block formation. The scattered wet pomace fermented feed enters the drying drum, and through the continuous rotation of the drum, the material is almost always in the air, reducing the contact time of the material with the drum wall, and avoiding agglomeration caused by sticking to the drum wall. After the dried pomace feed is decontaminated again, it enters the cooling bin, and is cooled by the action of the cooling fan. The cooled fruit pomace feed enters the silo to be powdered, and the pomace feed is crushed with a hammer mill according to the required particle size, with a particle size of 5.5mm; the produced du...

Embodiment 3

[0033] After Example 2, the pulverized pomace feed was granulated through the following process steps.

[0034] The crushed pomace feed enters the bin to be granulated, and then enters the modulator after being demagnetized by the permanent magnet cylinder, and the material is prepared before granulation with a steam pressure of 0.25-0.35Mpa. The compression ratio is used for granulation. The granulated pomace feed enters the cooling bin, and the granulated product is cooled by the action of the cooling fan. After cooling, the iron impurities are removed again, and then enter the vibrating grading screen for grading treatment. After processing, unqualified products are returned and processed again; products with qualified particle size enter the finished product warehouse, are weighed by electronic scales, and are packaged into products after entering the filling machine.

Abstract

The invention provides a process for preparing a feed by adopting lactobacillus acidophilus pomace. The process comprises two steps of a strain expanding propagation process and a pomace fermentation step, wherein the strain expanding propagation process is as follows: carrying out activation, cultivation, liquid cultivation and inoculating expanding cultivation onto lactobacillus acidophilus freeze-dried powder in sequence to obtain the lactobacillus acidophilus strain. The pomace fermentation step is as follows: after removing impurities for the fresh pomace, uniformly mixing with the lactobacillus acidophilus strain obtained by expanding propagation, sealing and fermenting for 7-10 days under a temperature condition of 15DEG C-30 DEG C to obtain the wet pomace fermented feed. After fermenting apple pulp by adopting the lactobacillus acidophilus, substances such as various alcohols, aldehyde, acetone, acids, esters, and the like with fragrance are produced, so that palatability of the pomace fermented feed is strengthened, and therefore, the lactobacillus acidophilus pomace fermented feed has effect of improving animal feed intake; and moreover, nutrient characteristics of the apple pulp are effectively improved, so that good material basis is provided for dairy cow yield increase. As a beneficial bacterium, the lactobacillus acidophilus improves anti-stress ability of animals and resistance to diseases.

Description

technical field [0001] The invention belongs to the field of feed production, and in particular relates to a pomace fermented feed, in particular to a pomace fermented feed using Lactobacillus acidophilus and a preparation process thereof. Background technique [0002] Apple pomace is solid waste in the production of apple juice. It is mainly composed of peel, core and residual pulp, accounting for about 25% of the quality of fresh fruit. Apple processing in my country discharges about 1 million tons of apple pomace every year. Apple pomace has a high water content (70-82%) and contains a large amount of soluble nutrients, which provide favorable conditions for the growth of microorganisms. Therefore, when fresh apple pomace is discarded, it is easy to rot and smell, seriously pollute the environment, and cause waste of resources. Apple pomace is rich in nutrients such as soluble sugar, vitamins, minerals and cellulose, and is a good feed resource. Therefore utilizing apple...
