Many factors can cause feed residue, mainly due to feed production process design, feed machinery manufacturing, and work accuracy. If corresponding measures are taken in process design and equipment selection, the generation of residue can be reduced.
In the process design, the transfer process uses the form of distributors and self-flow as much as possible and uses less horizontal transport. For horizontal conveying equipment, such as screw conveyors, scraper conveyors, due to structural reasons, these equipments have more or less residuals, and should be designed in such a way that materials can be easily accessed and can be easily cleaned, or Self-cleaning scraper conveyors can be used. In meeting the process requirements, the number of lifts of the materials and the number of transition hoppers are minimized. The suction and dust removal system sets up an independent wind network as far as possible, and the collected dust is directly sent back to the original place, so that it will not cause secondary pollution of the feed, and especially the production of the compounded premix for dosing should be treated as such. The measurement of trace components should be arranged as far as possible in the upper part of the mixer. If it must be lifted or transported after metering and weighing, high-density pneumatic transport must be used to prevent gradation and residue.
High-risk trace components of drugs must be added directly to the mixer. Special production lines are used as far as possible for medicated feed production in order to minimize the risk of cross-contamination. In order to reduce the impact of residual on feed, some clearing devices can be designed to use compressed air to clean certain parts of the equipment.
In the selection of equipment, the accuracy of the measuring equipment, electronic scales and mixing equipment should be determined. The measurement equipment and electronic scales should be determined according to the properties of materials with different proportions. Different measuring equipments should be used to meet different material quantities. Measurement requirements. In the production of compound feed and composite premix, the choice of mixer is important. The mixer should be able to achieve a mixing accuracy of no more than 5% with a variation ratio of one in 100,000. The design of the mixer should ensure that as little material as possible remains in the mixer after each batch is mixed. Due to different grain sizes and different requirements for final product production, in the production of pre-mixed feeds, the particle size of the materials is small, the mixing uniformity is high, the required residues are small, and the materials are electrostatically generated during the mixing process. When selecting the mixing machine, Taking full account of the characteristics of the mixed material, the requirements for the mixer are different. Bucket elevators, chutes, batching and buffering hoppers also produce residues. The internal surfaces of the chutes, silos, and hoppers are smooth, leaving no dead ends. Irrational liquid additions have an impact on the remnants of the material. .
To reduce the amount of material remaining in the feed processing process, it is first necessary to ensure that the material can be “first in, first out†in the equipment.
