Description

Technical Field

[0001] The present invention relates to the technical field of feed additive production, in particular to a production process and device for a feed additive containing active ingredients of plant essential oil. Background Art

[0002] In the modern animal feed industry, feed additives are key raw materials for improving the nutritional value of feed and ensuring animal health. Their green and safe development trend is becoming increasingly significant. Feed additives containing active ingredients of plant essential oils have become an important development direction to replace traditional antibiotics due to their antibacterial, anti-inflammatory and antioxidant properties. They play a key role in reducing drug residues and promoting healthy breeding. Among them, plant essential oils represented by eucalyptus oil have received widespread attention in the industry due to their significant antibiotic replacement effects and rich active ingredients. However, the current production process of feed additives containing active ingredients of plant essential oils still faces many technical bottlenecks. In the automatic feeding process, due to the strong volatility of plant essential oils and the fine particle size of some feed additive raw materials, traditional feeding equipment is difficult to accurately control the feeding amount, which easily leads to raw material volatilization loss and dust flying, which not only causes material waste, but also pollutes the production environment and endangers the health of operators. In the automatic mixing stage, the high volatility and strong permeability of plant essential oils make it difficult to achieve uniform dispersion when mixing with carriers and other auxiliary materials. Existing mixing equipment cannot effectively solve the problems of essential oil volatilization and uneven mixing, resulting in unstable product quality. In the process of adding essential oils, existing technologies mostly use manual addition or simple pipeline transportation methods. They lack precise metering and addition control devices, and cannot flexibly adjust the amount of essential oil added according to production needs, affecting product efficacy. The automatic packaging process also faces challenges. Feed additives containing plant essential oils have high requirements for the packaging environment. Traditional packaging equipment cannot effectively isolate air and moisture, which can easily lead to essential oil volatilization and product deterioration, reducing product shelf life and usage effects. In addition, if volatiles and floating materials generated during the production process are not handled in a timely manner, they will not only affect the health of production personnel, but also pose a safety hazard. Existing dust removal equipment is not effective in treating plant essential oil volatiles and cannot meet the requirements of environmental protection and safe production. In summary, the development of a feed additive production process and device containing plant essential oil active ingredients that can achieve automatic loading, precise mixing, accurate essential oil addition, efficient automatic packaging, and effective dust removal is of great significance for improving product quality, ensuring production safety, and promoting the green development of the feed additive industry.

[0042] It should be noted that the vibration loosening mechanism 8 is used to loosen the bagged material and evenly distribute it to the four corners of the bag. Specifically, it includes multiple rotating rollers 801 arranged in an array. These rotating rollers 801 are constructed of square steel. Compared to traditional round tube structures, their corners produce a more significant vibration effect, enhancing the loosening of the bagged material. These rotating rollers 801 rotate synchronously via a transmission system consisting of sprockets and chains. When the bagged material is conveyed above the rotating rollers 801, the vibration generated by the rotation of the rotating rollers 801 is transmitted to the material bag, causing the material in the bag to flow to the four corners of the bag under the action of vibration, achieving uniform distribution. This vibration loosening process effectively eliminates material accumulation in the bag and makes the material bag have a regular appearance. This design, on the one hand, allows the material bags to be stacked more firmly during the subsequent palletizing process due to their regular shape and uniform force, thereby improving palletizing efficiency and stability; on the other hand, it prevents the bags from being squeezed and broken due to local accumulation of materials and concentrated pressure, reduces packaging losses, ensures the safety of material storage and transportation, and effectively solves the problems of difficult and easy damage to bagged materials in the existing technology.

[0043] A production process for a feed additive containing active ingredients of plant essential oils comprises the following steps: S1, raw material preparation, selecting silicon dioxide or corn starch as a carrier, and drying and screening the carrier; S2, raw material mixing, putting the raw materials in step S1 into a mixing device for mixing, adding finished eucalyptus oil and continuously mixing, and then sequentially adding crushed and screened auxiliary materials and flavoring agents for mixing; S3, preparing a powder, screening the mixed material to remove lumps; S4, packaging, packaging and weighing the mixed finished material; in step S1, drying the carrier to reduce its moisture content to less than 5%; in step S1, the sieving particle size of the carrier is 50 mesh; the auxiliary material comprises one of an antioxidant and a stabilizer, and the flavoring agent comprises one of a sweetener and a spice.

[0044] It should be noted that, first, silicon dioxide or corn starch is selected as a carrier, and then transferred to the mixing mechanism 5 through the material lifting mechanism 9, and the carrier and the plant essential oil are fully mixed through the mixing box. During the mixing process, auxiliary materials and flavoring agents can be added as needed for mixing. Moreover, after the mixing is completed, some of the additives will clump due to humidity, so they are screened and filtered out by the screening mechanism, and finally packaged to form a finished product.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
