Finished feed.
[0063] Storage: Store the bagged silage products, and stack multiple bagged silage products during storage.
[0064]Silage fermentation is a maturation process in which temperature, moisture, air density and feed nutritional factors work together. There is a curve-shaped change between the fermentation temperature and the gas flow. The temperature is first gradually increased from 20°C to 30°C to 60°C to 65°C and then decreased to 20°C to 30°C. The fermentation time is about 30 days. The duration of continuous fermentation temperature change is 15 days, and the duration of constant temperature is 15 days. From the production practice, it is known that the temperature change stage of silage fermentation is the best time for exhaust gas. During this period, the moisture distribution in the finished bagged silage is 80%-85% in the bottom layer and 55%-60% in the middle layer. %, the upper layer is 65% to 70%.
[0065] The methods of the above-mentioned Embodiments 1 to 3 are provided with a top one-way exhaust valve 4 and a bottom one-way exhaust valve 3 at the corresponding positions of the inner bag 1, so that the gas and mist in the silage fermentation period can be discharged in time, thereby reducing Water retention and stratification, feed corruption, reduce the breakage rate of stacking inventory extrusion, improve silage quality, animal feed digestibility and breeding economic benefits.
[0066] Among them, the distance between the bottom one-way exhaust valve 3 and the short hot melt line 12 and the long hot melt line 11 is a predetermined value, and the distance between the top one-way exhaust valve 4 and the top edge of the opening of the inner bag 1 is a predetermined value. 1. When the opening is sealed, the top one-way exhaust valve 4 is located between the binding rope 5 and the bottom one-way exhaust valve 3. Due to the joint action of these three steps, it can ensure that the scraps are compressed and packed into the inner bag 1. The bottom of the compressed feed corresponds to the bottom one-way exhaust valve 3, and the top of the compressed feed corresponds to the top one-way exhaust valve 4, that is, it can ensure that the bottom one-way exhaust valve 3 and the top one-way exhaust valve 4 are located in the inner bag 1. The collection area of ​​residual gas and fermentation gas, so as to ensure that the mist and gas generated in the silage fermentation process are discharged from the bottom one-way exhaust valve 3 and the top one-way exhaust valve 4 in time.
[0067] "Anti-mildew treatment" is performed before the step "sealing", and the mist generated during the silage silage fermentation process drifts along the direction from the bottom one-way exhaust valve 3 to the top one-way exhaust valve 4 to the inner bag 1 away from the bottom one-way exhaust One side of the air valve 3, if the mist still cannot be discharged from the top one-way exhaust valve 4 in time, and the side of the inner bag 1 away from the bottom one-way exhaust valve 3 condenses into water droplets, and the water droplets drop to the mixed antibacterial. The powder is mixed with the mixed antibacterial powder, and the corn steep liquor dry powder can absorb water to prevent the water droplets from contacting the silage on the side away from the one-way exhaust valve 3 at the bottom, and the water absorbed by the corn steep liquor dry powder can be absorbed by the compound bacteria powder. The bacteria are directly used, thereby reducing the possibility of spoilage bacteria growth and development, thereby further avoiding mildew and spoilage of silage.
[0068] In addition, the inner bag 1 is not equipped with redundant one-way exhaust valves, which can avoid the exhaust of excessive gas and mist during the fermentation process and ultimately affect the quality of the fermented product.
