Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of compound microbial fermented feed and preparation method thereof, to solve the above-mentioned background technology and propose the preparation method of existing compound microbial fermented feed, it is inconvenient to realize the even mixing of feed, cause the bottom raw material to be difficult to realize fermentation very well At the same time, there are gaps in the mixed feed, which is inconvenient to carry out stable compaction operation on the feed, which affects the fermentation efficiency of the feed. The fermentation of the feed needs to be controlled by temperature. Most of the existing methods for preparing the compound microbial fermented feed are fermented. Heating from the outside leads to a large temperature difference between the inside and outside of the feed, which is inconvenient to stabilize the temperature control of the feed, which is also an important factor affecting the fermentation effect of the feed.

Embodiment 1

[0036] see Figure 1-3 , the preparation method comprises the following steps:

[0037] Step 1: crushing and mixing straw powder, fish meal, corn meal and rapeseed meal;

[0038] Step 2: Inoculate Bacillus subtilis, Clostridium butyricum, Aspergillus niger and Saccharomyces cerevisiae in the culture medium for activation, and then inoculate in the fermentation medium for cultivation after activation to obtain the bacterial liquid;

[0039] Step 3: Put the pulverized and mixed raw materials in step 1 and the bacterial liquid obtained in step 2 into a fermenter for fermentation, and then take out the fermented feed;

[0040] Wherein, the fermentation tank in step 3 includes a tank body 1, a feed hopper 2 is fixed through the top edge of the tank body 1, and a motor 3 is installed at the bottom of the tank body 1, and the output end of the motor 3 is connected with a mounting column 4, And the mounting column 4 bearings are installed in the middle part of the inside of the tank...

Embodiment 2

[0042] see Figure 1-3 and Figure 7 , the liquid inlet pipe 14, the liquid inlet pipe 14 runs through and is fixed on the top of the tank body 1, and one end of the liquid inlet pipe 14 is located at the through hole for liquid inlet opened on the side of the installation column 4, and the position of the cavity in the installation column 4 An extrusion column 15 is installed through it, and the middle part of the extrusion column 15 is covered with a piston sealing ring 16. The top of the extrusion column 15 is located at the upper end of the tank body 1, and the protruding position of the top of the extrusion column 15 is in line with the bottom of the tank body 1. A spring 17 is fixed between the upper ends, a pressure rod 18 is installed through the top of the tank body 1, and the bottom of the pressure rod 18 is located in the tank body 1, and the bottom of the pressure rod 18 is installed in the movable groove 19, and the movable groove 19 is opened On the top of the m...

Embodiment 3

[0044] see figure 1 and Figure 4-6 Among them, the installation rings 5 ​​are sleeved on the installation columns 4 at equal intervals, and the upper and lower installation rings 5 ​​are connected by elastic telescopic rods 51. The bottom of the pressure rod 18 is designed in a spherical structure, and the bottom of the pressure rod 18 is movable. The groove 19 fits and rotates, and the pressure rod 18 is fitted and installed on the top of the tank body 1 at an equal angle. The pressure rod 18 is pressurized by the counterweight 20, and the pressure rod 18 drives the installation ring 5 and the partition plate 11 to move downward. Squeeze the feed to avoid gaps inside the feed and affect the fermentation effect.

[0045] Working principle: when using the preparation method of the compound microbial fermented feed, first as Figure 1-4 In the process, the prepared raw materials are poured into the feed hopper 2 on the tank body 1, and the raw materials are dropped from the s...

Abstract

The invention discloses a compound microbial fermentation feed and a preparation method thereof. The preparation method comprises the following steps: step 1, crushing and mixing straw powder, fish meal, corn flour and rapeseed meal; 2, bacillus subtilis, clostridium butyricum, aspergillus niger and saccharomyces cerevisiae are inoculated into a culture medium to be activated; step 3, putting the raw materials crushed and mixed in the step 1 and the bacterial liquid obtained in the step 2 into a fermentation tank for fermentation; wherein the fermentation tank in the step 3 comprises a tank body, and a feed hopper is fixed at the edge of the top of the tank body in a penetrating manner; and the mounting ring is arranged outside the mounting column in a sleeving manner. According to the compound microbial fermented feed and the preparation method thereof, during fermentation operation, the raw materials are mixed by adding a bacterial liquid in a layered manner, so that the mixing uniformity is improved, the raw materials and the bacterial liquid can be uniformly heated, meanwhile, compaction operation can be performed according to different raw materials, and the situation that the fermentation effect is affected due to gaps is avoided.

Description

technical field [0001] The invention relates to the technical field of compound microbial fermented feed, in particular to a compound microbial fermented feed and a preparation method thereof. Background technique [0002] Compound microbial fermented feed is fermented by adding microorganisms to feed raw materials, which is used to eliminate antigens in the feed and improve feed palatability and nutrient conversion rate, which helps to improve the feeding effect. Most of the compound microbial fermented feeds need to be made by fermentation. But the preparation method of existing composite microbial fermented feed has the following problems in use: [0003] For the feed processing of some small-scale farmers, most of the existing methods for preparing compound microbial fermented feed are to pour the raw materials and bacterial liquid into the fermenter for autohedral fermentation, which is inconvenient to achieve uniform mixing of the feed. As a result, it is difficult to...
