Problems solved by technology

[0004] The technical problem mainly solved by the present invention: the existing antifungal agents have poor antibacterial and antifungal effects, short action time, narrow antibacterial spectrum, strong volatility, large heat loss, corrosion of production equipment, and harm to the health of production personnel. The defect is to provide a mildew-proof base material by using anti-mold organic acid to modify corn cobs and walnut shells, and to prepare natural and durable feed anti-mold agents from shells and modified gelatinized corn. Crush the mixed powder, modify it with sodium diacetate and calcium propionate to obtain an anti-mildew substrate, then calcinate the shells and put them into gauze for modification for later use, then gelatinize cornstarch and β-cyclodextrin with sucrose Esters, kaempferol, etc. are mixed, then the gelatinized product is mixed with the anti-mildew base material and the substance in the gauze, and then freeze-dried, and finally ground and packaged to obtain a natural and durable feed anti-mold agent. The natural and long-lasting feed anti-mold agent of the present invention The anti-fungal agent has a wide antibacterial spectrum, long-lasting and obvious anti-mold effect, and good stability during production and use. The anti-mold agent is not easy to volatilize, will not cause corrosion to production equipment, is harmless to the human body, and has a wide application prospect

example 1

[0017] First, weigh 200g of corncob and 100g of walnut shell and put them in an oven, dry them at 100°C to constant weight, put them into a pulverizer after drying, and pass through a 80-mesh sieve to obtain corncob powder and walnut shell powder respectively, stir and mix After uniformity, the mixed powder is obtained. Mix the mixed powder with water at a mass ratio of 1:10. After stirring and mixing, add 5 g of sodium diacetate and 10 g of calcium propionate. After stirring and mixing for 20 minutes, suction filter to obtain a filter residue, and put it in an oven. Dry at 70°C for 8 hours to obtain a mildew-resistant base material for use; then weigh 200g of shells, put them into a muffle furnace, and heat up to 500°C for 30 minutes to obtain calcined products, which are wrapped in gauze and hung on charcoal At the exit of the kiln, stack 1kg of dry wood at the bottom of the charcoal kiln, and stack 300g of bamboo on the surface of the wood, raise the temperature of the charc...

example 2

[0020]First, weigh 250g of corn cob and 150g of walnut shell and put them in an oven, dry them at 103°C to constant weight, put them into a pulverizer after drying, and pass through a 90-mesh sieve to obtain corn cob powder and walnut shell powder, stir and mix After uniformity, the mixed powder is obtained. Mix the mixed powder with water at a mass ratio of 1:10. After stirring and mixing, add 8g of sodium diacetate and 11g of calcium propionate. After stirring and mixing for 25 minutes, suction filter to obtain a filter residue, and put it in an oven. Dry at 75°C for 9 hours to obtain a mildew-resistant base material for use; then weigh 250g of shells, put them into a muffle furnace, heat up to 600°C and calcinate for 35min to obtain calcined products, wrap them in gauze, and hang them on charcoal after wrapping At the exit of the kiln, stack 1 kg of dry wood at the bottom of the charcoal kiln, and stack 400 g of bamboo on the surface of the wood, raise the temperature of the...

example 3

[0023] First weigh 300g of corncob and 200g of walnut shell and put them in an oven, dry them at 105°C to constant weight, put them into a pulverizer after drying, and pass through a 100-mesh sieve to obtain corncob powder and walnut shell powder respectively, stir and mix Mix the powder evenly to get mixed powder, mix the mixed powder with water at a mass ratio of 1:10, stir and mix, then add 10g of sodium diacetate and 12g of calcium propionate, stir and mix for 30min, then suction filter to get the filter residue, and put it in an oven. Dry at 80°C for 10 hours to obtain a mildew-proof base material for use; then weigh 300g of shells, put them into a muffle furnace, heat up to 700°C and calcinate for 40 minutes to obtain calcined products, wrap them in gauze, and hang them on charcoal after wrapping. At the exit of the kiln, stack 2kg of dry wood at the bottom of the charcoal kiln, and stack 500g of bamboo on the surface of the wood, raise the temperature of the charcoal kil...

Abstract

The present invention discloses a preparation method of a natural and long-lasting feed mildew preventive and belongs to the technical field of feed additive preparations. Firstly, corn cobs and walnut shell powder are crushed into a mixed powder, the mixed powder is modified with sodium diacetate and calcium propionate to obtain a mildew preventive base material, then pearl shells are calcined, the calcined pearl shells are put into a gauze to conduct a modification for a standby application, then corn starch and beta-cyclodextrin are gelatinized, the gelatinized materials are mixed with sucrose ester, kaempferol, etc., then the mixed gelatinized materials, the mildew preventive base material and substances in the gauze are mixed and wrapped, the wrapped mixture is freeze-dried, finally the freeze-dried mixture is ground, and the ground mixture is packaged to obtain the natural and long-lasting feed mildew preventive. The natural and long-lasting feed mildew preventive is wide in antimicrobial spectrum, long-lasting in mildew preventing, obvious in effects, good in stability during production and use, and not easily volatile, does not cause corrosion to production devices, is harmless to the human body and has a wide range of application prospects.

Description

technical field [0001] The invention discloses a preparation method of a natural long-lasting feed antifungal agent, which belongs to the technical field of feed additive preparation. Background technique [0002] According to research, the average annual loss of feed in the world is about 20% of the total output, and more than half of it is caused by feed mildew. After the feed is rotten and rotten, in addition to being unable to directly use it and causing serious economic losses, the livestock and poultry will accumulate poisoning after eating the rotten and rotten feed, and even die. Economic losses have seriously affected the development of feed industry and animal husbandry production. At the same time, the residues of mycotoxins in livestock products also pose a great threat to human health. The contamination of feed by mold and mycotoxins has become a problem that cannot be ignored in the production of feed and animal husbandry. [0003] The mechanism of action of...
