The water-in-oil nanoemulsion has the advantages of high drug loading capacity, good skin permeability, high retention volume in skin cells, high bioavailability, good stability, high safety and the like, and can be used in pure oil cosmetics.

The invention discloses a fattening pig feed added with feed lard and a preparation method of the fattening pig feed. The feed is prepared from the following raw materials in parts by weight: 560.7 to 587.2 parts of corn, 150 to 165 parts of soybean meal, 85 to 105 parts of wheat middling, 50 to 80 parts of rice bran meal, 30 to 47 parts of corn germ meal, 15 to 25 parts of cottonseed meal, 11 to 14 parts of mountain flour, 2 to 2.5 parts of sodium chloride, 5 to 8 parts of calcium hydrogen phosphate, 5 to 10 parts of soybean oil, 15 to 25 parts of compound vitamin liposome and 0.9 to 1.1 parts of trace element mixed feed, the lard oil is compounded with the soybean oil, so that the addition amount of the soybean oil is reduced. Meanwhile, the lard oil and the vitamins are added into the feed in the form of lipidosome, so that rancidity of the lard oil can be avoided, and the vitamin lipidosome is added into the pig feed, so that the bioavailability of the vitamins can be remarkably improved, the healthy growth and reproductive performance of pigs are promoted, and related diseases are prevented.

The invention belongs to the technical field of descaling equipment, and particularly discloses anti-scaling, descaling and anti-corrosion equipment and a using method thereof.The anti-scaling, descaling and anti-corrosion equipment comprises a shell, sealing flange plates are fixedly installed on the outer walls of the two ends of the shell, a descaling device main machine is fixedly installed on the outer wall of the shell, an electrode is fixedly installed on the inner wall of the shell, and the outer contour of the electrode is matched with the inner contour of the shell; the cleaning assembly is connected with the shell and the electrode; the replacement assembly is connected with the shell and the cleaning assembly; and the filtering piece is connected with the cleaning assembly and the replacing assembly. By arranging the filter part, after the filter part is blocked and pushed by water, the replacement assembly can be driven to replace the filter part, so that the influence on water circulation and the adsorption and filtration effect on impurities and floating crystals is avoided; the cleaning assembly is driven to clean the electrode, the situation that impurities adhere to the electrode, and the water treatment effect is affected is avoided, the impurities in water and suspended crystals formed by a high-frequency electromagnetic field can be adsorbed and filtered, and the impurities in the water are reduced.

The application discloses a high-heredity-performance high-health-degree pig whole-process nutrition precise feeding method, and particularly relates to the pig scale breeding technical field, and comprises seven-stage fine feed design from the teaching trough milk powder material to the fattening material, and the whole process adopts the automatic dry and wet trough for feeding from the teaching trough granule material stage, and a three-stage progressive growth constraint relationship is established, and the three are closely related and indispensable; meanwhile, the mixed weight ratio of the feed and water is strictly fixed in the rearing stage, a semi-liquid uniform porridge material is formed, and the water-feed ratio is dynamically controlled in the growth and fattening stage. Through the cooperation of the stage target control and the staged precise liquid feeding, the technical contradiction that the early feeding amount and the dry matter intake amount of the high-heredity-performance pig are difficult to be considered is solved, the growth potential of the pig is fully tapped under the premise of guaranteeing the high health degree, and the application has the significant advantages of low feed-meat ratio, high health degree and good uniformity of the marketable pigs.

This invention discloses a papaya wine sampling device for a fermentation tank, relating to the field of fermentation equipment technology. Its key technical features include a fermentation tank and a fermentation tank support fixedly installed at the bottom of the tank. A sealing cap is bolted to the top of the fermentation tank, and a papaya wine discharge valve is fixedly installed at the center of the bottom of the fermentation tank. A sampling structure is provided on the fermentation tank. This invention employs a closed sampling structure. After the wine flows into the sampling tube, the valve is closed to create an anaerobic environment. A hydraulic rod drives the sealing plug to open the one-way valve for sampling, avoiding negative pressure oxygen absorption and preventing microbial intrusion into the fermentation tank. A magnetically driven filter assembly is simultaneously configured; a hemispherical filter screen intercepts impurities and is self-cleaned by a scraper, while the wine is stirred to prevent stratification. A cleaning assembly is added; a water pump draws water and flushes the flow channel through a hollow push rod. Finally, residual liquid is collected by tilting the adjusting rod, and inert gas is pressurized and discharged to establish a positive pressure gas seal, providing multiple guarantees for subsequent aseptic sampling.
