[0054] Embodiment three:
[0055] like Figure 1 to Figure 3 As shown, the third preferred embodiment of the present invention provides a processing method of bagged silage with a one-way exhaust valve, the following steps:
[0056] Preparation of raw materials: The raw materials are processed into scraps. Specifically, the straws containing fibers are processed by the grass cutter or silk kneading machine in the prior art. Specifically, the model of Luoyang Sida Agricultural Machinery Co., Ltd. is 9Z-30. The raw material is processed by a guillotine; the length of the scrap is 2 cm.
[0057] Cutting the inner bag raw material: Take the recycled plastic and cut it into two rectangular plastic sheets, wherein the recycled plastic is polyethylene, the thickness of the recycled plastic is 0.05mm, the color of the recycled plastic is blue, the length of the rectangular plastic sheet is 145cm, and the width is 82cm .
[0058] Hot-melt bag: two long sides and one short side of two rectangular plastic sheets are hot-melted to form an inner bag 1 including two long hot-melt lines 11 and one short hot-melt line 12. , using a hot-melt machine in the prior art to perform hot-melt sealing treatment on two rectangular plastic sheets, which is a prior art operation and will not be repeated here. The distance between the long hot melt line 11 and the long side corresponding to the rectangular plastic sheet is 3 cm, and the distance between the short hot melting line 12 and the short side corresponding to the rectangular plastic sheet is 3 cm.
[0059] Install one-way exhaust valve: Install two bottom one-way exhaust valves 3 on each rectangular plastic sheet at intervals, and the distance between each bottom one-way exhaust valve 3 and the short thermal fuse line 12 is 5cm, and each bottom one-way exhaust valve 3 is 5cm. The distance between the exhaust valve 3 and the corresponding long hot melt line 11 is 5 cm; a top one-way exhaust valve 4 is installed at the position of each rectangular plastic sheet 30 cm away from the top edge of the opening of the inner bag 1 . Specifically, the bottom one-way exhaust valve 3 and the top one-way exhaust valve 4 are selected from the one-way exhaust valve HZ-3 type of Huazhong Industrial Co., Ltd., Shunde District, Foshan City, and the Chinese invention patent with publication number CN105774044B is adopted. The portable exhaust valve heat press inlays the corresponding one-way exhaust valve in the corresponding position.
[0060] Bagging: Pack the scraps into the inner bag 1 with a hydraulic baler. Specifically, the hydraulic baler adopts the three-cylinder hydraulic silage baler model 9YK-70 of Hebei Tangshan Taiyihe Machinery Co., Ltd., which can compress the scraps into cubes, with a total length of 145cm, a width of 24cm, and a height of 36cm. The feed segment is 60cm long. First put the inner bag 1 into an outer bag 2, the length of the outer bag 2 is 148cm, the width is 85cm, and the outer bag 2 is a breathable nylon woven bag. Keep the opening of the inner bag 1 coincident with the opening of the outer bag 2, and then put the opening of the inner bag 1 and the outer bag 2 into the raw material outlet of the hydraulic baler, and make the bottom of the inner bag 1 and the outlet of the hydraulic baler. Correspondingly, the length of the inner bag 1 covering the outlet of the hydraulic baler is 60cm. At this time, it must be ensured that the bottom of the inner bag 1 is fitted with the outlet of the hydraulic baler. The crushed material is compressed by the hydraulic baler to form compressed feed. The compressed feed is pushed from the outlet of the hydraulic baler into the inner bag 1. After the compressed feed is pushed into the inner bag 1, the top surface of the compressed feed is located at the top one-way exhaust valve 4. Between the opening of the inner bag 1, in this process, the inner bag 1 and the outer bag 2 are pushed out and separated from the outlet of the hydraulic baler together with the compressed feed under the thrust of the hydraulic baler.
[0061] Anti-mildew treatment: add mixed antibacterial powder on the top surface of the scrap material away from the short hot melt line 12, and the mixed antibacterial powder includes the following parts by weight: 9 parts of corn steep liquor dry powder and 1 part of compound bacteria powder. Specifically, 9 parts of corn steep liquor dry powder and 1 part of compound bacteria powder are evenly sprinkled on the top surface of the compressed feed away from the short hot melt line 12 after stirring and mixing, and the thickness of the mixed antibacterial powder is 5 cm. Wherein, corn steep liquor dry powder is selected from northeast corn flour, and its moisture is less than or equal to 13, pulverized to 9 meshes, and the aperture is 1.5 mm; composite bacterial powder is selected from composite microorganism additive I of Nanning Weirui Biotechnology Co., Ltd.
[0062] Sealing: The opening of the inner bag 1 is sealed to obtain the finished product of bagged silage. Specifically, the openings of the inner bag 1 and the outer bag 2 are bound and sealed with the binding rope 5, and the top one-way exhaust valve 4 is located between the binding rope 5 and the bottom one-way exhaust valve 3 to obtain bagged silage. 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.
