DETAILED DESCRIPTION

[0031] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1-6 As shown:

[0033] A method for preparing chicory silage comprises the following steps:

[0034] (1) Timely harvesting: The harvesting time of chicory has a great influence on the quality of silage. Generally, it is best to harvest chicory from the bud to the flowering stage. At this time, the nutritional value of chicory is higher and the yield is also considerable. When harvesting, the stubble height is controlled at 5-8 cm to facilitate the subsequent regeneration of chicory.

[0035] (2) Raw material cleaning: After harvesting, chicory should be cleaned in time to remove weeds, dirt, stones, moldy parts and other debris mixed in it to ensure the purity of the silage raw materials.

[0036] (3) Mincing: Use a hay mower or silage chopper to mince the cleaned chicory. A minced length of 1-2 cm is more appropriate. This length is conducive to compaction and expelling air from the raw materials. It is also easier for livestock to eat and digest.

[0037] (4) Adjusting moisture: When silaging chicory, appropriate moisture content is crucial. Generally, the moisture content should be controlled at 65%-75%. To determine whether the moisture content is appropriate, you can use a simple hand-holding method: grab a handful of chopped chicory and hold it tightly. If water seeps out between your fingers but does not drip, it means that the moisture content is relatively appropriate; if no water seeps out, it means that the moisture content is too low and you need to spray water appropriately; if water drops fall in clusters, the moisture content is too high and you can adjust the moisture by drying it in the sun or adding dry feed (such as bran, hay powder, etc.).

[0038] (5) Adding additives: In order to promote lactic acid fermentation and improve the quality of silage, lactic acid bacteria preparations or compound bacteria (commercial lactic acid compound bacteria) and appropriate amounts of sugar substances can be added to chicory; generally, 30-50 grams of lactic acid bacteria preparations are added per ton of chicory, which can effectively reduce the pH value of silage, inhibit the growth of harmful microorganisms, and improve the success rate of silage. At the same time, adding an appropriate amount of sugar substances (such as brown sugar, corn flour, etc.) can provide sufficient substrate for lactic acid fermentation and accelerate the lactic acid fermentation process. Generally, 2-3 kg of brown sugar or 3-5 kg ​​of corn flour are added per ton of chicory and evenly sprinkled on the chopped chicory.

[0039] (6) Rapid fermentation: The chicory treated in step 5 is placed in a rapid fermentation device for closed fermentation. The temperature is maintained at 35-40° C. during the fermentation process. The rapid fermentation is performed for 12-15 hours. After the fermentation is completed, the solid fermentation product and the fermentation liquid are separated. The fermentation liquid is used for the next rapid fermentation process. Since the fermentation liquid contains a large number of mature bacterial flora, the progress of the next fermentation can be accelerated. The fermentation process is carried out in sequence. As the fermentation liquid accumulates, the fermentation speed will also increase accordingly.

[0040] (7) Slow fermentation: Place the fermented chicory into the silo and compact it, seal it with a film, cover the plastic film with a 20-30 cm thick layer of wet soil, pat it tightly, and slowly ferment it for 10-12 days.

[0041] The present invention performs a rapid fermentation before performing conventional slow fermentation. By artificially controlling the fermentation temperature and environment, the bacterial flora can reproduce and ferment rapidly, which greatly reduces the subsequent fermentation process. Conventionally, slow fermentation generally takes 3 to 4 weeks to complete at a temperature of 15 to 25°C, and takes 2 to 3 weeks to complete at a temperature of 25 to 35°C. By performing rapid fermentation followed by slow fermentation, the fermentation cycle can be greatly shortened.

[0042] application:

[0043] Feeding ruminants

[0044] Dairy cows: Chicory silage is rich in nutrients such as protein, vitamins and minerals, and can be used as a high-quality roughage source for dairy cows. Proper addition of chicory silage to dairy cows' diets can increase their feed intake and milk production. Generally, during the peak period of milk production, 15-20 kg of chicory silage can be added to each cow per day, which can effectively improve milk quality and increase milk protein and fat content.

[0045] Beef cattle: For beef cattle breeding, chicory silage helps the growth and fattening of beef cattle. Adding 10-15 kg / day of chicory silage to the daily diet of fattening cattle can replace part of the hay and silage corn, reducing feeding costs. At the same time, the nutrients in chicory silage can promote digestion and absorption of beef cattle, and improve the growth rate and meat quality of beef cattle.

[0046] Sheep: Sheep have a good palatability for chicory silage. 3-5 kg / day of chicory silage can be added to the daily diet of sheep. Especially in winter when green feed is scarce, chicory silage can provide sheep with necessary nutrition to maintain their growth and production performance. For breeding ewes, adding an appropriate amount of chicory silage can help improve the reproductive performance of ewes and the survival rate of lambs.

[0047] Feeding monogastric animals

[0048] Pigs: Chicory silage can be added to the diet of pigs in an appropriate amount, generally accounting for 10%-20% of the diet. The dietary fiber in chicory silage can promote intestinal peristalsis of pigs, improve the digestive function of pigs, and reduce the occurrence of constipation. At the same time, its rich nutrients help improve the quality of pork, making pork more tender and juicy.

[0049] Rabbit: Rabbits are herbivorous animals and prefer chicory silage. Adding an appropriate amount of chicory silage to the rabbit's diet (generally 20%-30% of the diet) can meet the rabbit's fiber needs and prevent digestive tract diseases. Chicory silage has good palatability and can also increase the rabbit's feed intake and promote the growth and development of the rabbit.

[0050] In view of the above process, the applicant has also developed a device for rapid fermentation.

[0051] Reference Figure 1-Figure 6 A rapid fermentation device comprises a fermentation barrel 1, the top of the fermentation barrel 1 is rotatably connected with a stirring shaft 4 penetrating therethrough, the stirring shaft 4 is hollow and has a first slideway 10 on its circumference, a slide plate 11 is slidably connected in the first slideway 10, a sliding sleeve 12 is fixedly connected to the circumference of the slide plate 11, a spiral material pressing piece 5 is fixedly connected to the circumferential outer wall of the sliding sleeve 12, when the stirring shaft 4 rotates, the spiral material pressing piece 5 is also driven to rotate, and the floating raw material is pressed downward by the material pressing piece 5 to prevent the raw material from floating and improve the fermentation effect, a plurality of stirring blades 6 for stirring the raw material are fixedly connected to the bottom of the stirring shaft 4, and the stirring shaft 4 drives the stirring blades 6 to stir the raw material, so as to facilitate the mixing of the main material and the auxiliary material;

[0052] A fixed plate 13 is fixedly connected to the top of the stirring shaft 4, and a first motor 14 is fixedly connected to the top of the fixed plate 13. A threaded rod 15 is fixedly connected to one end of the output shaft of the first motor 14. The threaded rod 15 threads through the slide plate 11. The first motor 14 drives the threaded rod 15 to rotate, and the threaded rod 15 drives the slide plate 11, the sliding sleeve 12 and the pressing sheet 5 to move downward, thereby being able to suppress the solid raw material, so that the liquid in the solid raw material can be repeatedly squeezed out, reducing waste and improving the liquid output rate. A second motor 16 is fixedly connected to the top of the fermentation barrel 1, and a gear 17 is fixedly connected to one end of the output shaft of the second motor 16 and the circumference of the stirring shaft 4. The two gears 17 are meshed, and the second motor 16 drives the stirring shaft 4 to rotate through the gear 17.

[0053] In the present invention, a heat preservation sleeve 2 is fixedly connected to the circumferential outer wall of the fermentation barrel 1, a heating wire 3 is fixedly installed in the heat preservation sleeve 2, and the heating wire 3 is started to heat the fermentation barrel 1 to keep the temperature in the fermentation barrel 1 at 35-40°C.

[0054] In particular, a feed hopper 8 is fixedly connected to the top of the fermentation barrel 1 , and a top cover 9 is threadedly connected to the top of the feed hopper 8 , so that feeding is conveniently performed through the feed hopper 8 .

[0055] It should be noted that the top of the top cover 9 is fixedly connected with an exhaust pipe 22 that penetrates therethrough, a second slideway 23 is opened on the circumference of the exhaust pipe 22, an adjusting plate 24 is slidably connected in the second slideway 23, a plug 26 is slidably connected in the exhaust pipe 22, and a first spring 25 is fixedly connected between the plug 26 and the adjusting plate 24. The gas generated during the fermentation process pushes the plug 26 upward, thereby discharging the gas in the fermentation barrel 1, thereby improving the safety of use.

[0056] In the present invention, the top of the exhaust pipe 22 is rotatably connected with an adjusting rod 27 that penetrates through the adjusting plate 24. By rotating the adjusting rod 27, the height of the adjusting plate 24 can be adjusted, thereby facilitating automatic exhaust and discharging, thereby improving safety in use.

[0057] In particular, a discharge pipe 7 is fixedly connected to the bottom of the fermentation barrel 1, a bottom cover 19 is threadedly connected to the bottom of the discharge pipe 7, a discharge pipe 21 is fixedly connected to the bottom of the bottom cover 19, a control valve is installed at the bottom of the discharge pipe 21, and the discharge pipe 21 is used to discharge the fermented liquid.

[0058] It should be noted that a filter box 20 is fixedly connected to the bottom cover 19, and the top of the filter box 20 is flush with the bottom inner wall of the fermentation barrel 1. Solid impurities are blocked by the filter box 20, and the stirring blade 6 can push away the solids on the surface of the filter box 20 when rotating, thereby improving the liquid discharge effect.

[0059] In the present invention, a sleeve 28 is fixedly connected to the top of the fermentation barrel 1, and a rod 29 is slidably connected inside the sleeve 28. A second spring 30 is fixedly connected between the rod 29 and the top inner wall of the fermentation barrel 1. A wedge 18 used in conjunction with the rod 29 is fixedly connected to the surface of the pressing sheet 5. After the wedge 18 contacts the roller 31, the rod 29 is pushed upward by the roller 31. After the contact is broken, the rod 29 is reset under the action of the second spring 30, and then collides with the pressing sheet 5, so that the raw material is shaken off, preventing the raw material from staying on the pressing sheet 5.

[0060] In particular, the bottom of the insertion rod 29 is rotatably connected to a roller 31, and the roller 31 reduces the friction during contact.

[0061] When in use, remove the top cover 9, put the fermented raw materials into the fermentation barrel 1 through the feed hopper 8 for fermentation, and close the top cover 9 to maintain the fermentation environment. During fermentation, start the heating wire 3 to heat the fermentation barrel 1 to keep the temperature in the fermentation barrel 1 at 35-40°C;

[0062] After the raw materials are put into the fermentation barrel 1, the second motor 16 is started. The second motor 16 drives the stirring shaft 4 to rotate through the gear 17. The stirring shaft 4 drives the stirring blades 6 to stir the raw materials to facilitate the mixing of the main material and the auxiliary material. At the same time, when the stirring shaft 4 rotates, it also drives the spiral pressing piece 5 to rotate. The raw materials are pressed downward by the pressing piece 5 to avoid fluffing due to the generation of gas during the fermentation process.

[0063] When the pressing sheet 5 rotates, the wedge block 18 is driven to rotate. After the wedge block 18 contacts the roller 31, the roller 31 pushes the insertion rod 29 upward. After the contact is broken, the insertion rod 29 is reset under the action of the second spring 30, and then collides with the pressing sheet 5, so that the raw material is shaken off, preventing the raw material from staying on the pressing sheet 5.

[0064] S5: The gas generated during the fermentation process pushes the plug 26 upward, thereby discharging the gas in the fermentation barrel 1. At the same time, the plug 26 keeps blocking the exhaust pipe 22 under the action of the first spring 25 to prevent bacteria from entering the fermentation barrel 1. By rotating the adjusting rod 27, the height of the adjusting plate 24 can be adjusted, thereby facilitating automatic exhaust and discharging, thereby improving the safety of use;

[0065] S6: During discharge, the liquid is discharged through the discharge pipe 21, and the solid is blocked by the filter box 20. When the stirring blade 6 rotates, it can push away the solid on the surface of the filter box 20 to improve the liquid discharge effect. The first motor 14 is started, and the first motor 14 drives the threaded rod 15 to rotate. The threaded rod 15 drives the slide plate 11, the sleeve 12 and the pressing sheet 5 to move downward, which can suppress the solid raw material, so that the liquid in the solid raw material can be repeatedly squeezed out.

[0066] This equipment has the following advantages:

[0067] By installing a spiral pressing piece in the fermentation barrel, the pressing piece can be used to press down the floating raw materials, and can suppress the solid raw materials during liquid discharge, so that the liquid in the solid raw materials can be repeatedly squeezed out, reducing waste and improving the liquid output rate.

[0068] An exhaust pipe is installed on the top of the top cover, and a plug is installed in the exhaust pipe. The plug can prevent bacteria from entering the fermentation barrel, and at the same time can facilitate automatic exhaust and discharge, thereby improving safety in use.

[0069] The wedge block and the insert rod are used in coordination so that the insert rod can collide with the pressing sheet, thereby causing the raw material to fall off and preventing the raw material from staying on the pressing sheet.

[0070] The arrangement of installing a filter box in the discharge pipe enables the solid raw material to be filtered through the filter box, thereby facilitating the discharge of the liquid.

[0071] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
