Description

Technical Field

[0001] This invention relates to the field of feed additive equipment technology, and in particular to a multi-component feed additive coating device. Background Technology

[0002] Feed additives are essential materials in the livestock farming industry, used to prevent mold and oxidation of basic feed. With the development of livestock farming, the role of feed additives is no longer limited to mold prevention and anti-oxidation, but is developing towards increasingly complex functional designs, such as improving immunity and increasing nutritional levels. As a result, the research and application of multi-component feed additives have become a hot topic.

[0003] In actual production, the preparation of feed additives with multi-component formulations faces the following challenges: 1. Due to the constraint of coating uniformity control, it is impossible to simultaneously use multiple components to coat the core material, resulting in low coating efficiency. The number of coating process steps and the process time increase with the increase of the number of coating components, causing losses of coating materials and core materials, and reducing the effectiveness of coating materials and core materials; 2. Due to component segregation and process errors leading to uneven dispersion, and constrained by the process requirements of coating integrity, it is difficult to accurately control the coating ratio, and it is even more impossible to dynamically adjust the coating ratio during the coating operation.

[0051] The application principle of the multi-component feed additive coating device in this embodiment is as follows:

[0052] Solid or semi-solid core material is loaded into the core material supply section B1. The inner supply pipe C1 and the outer supply pipe C3 are connected to different external liquid or semi-solid material component supply devices. Different liquid or semi-solid material components are supplied to the inner supply pipe C1 and the outer supply pipe C3 through the external devices. Under the action of the external driving device, the different liquid or semi-solid material components are sprayed upward through the first spray component C2 and the second spray component C4 to form atomized coating material fluid. The drive motor E is started to drive the core material supply section B1 to rotate. Under the action of centrifugal force, the core material in the core material supply section B1 is ejected through the core material output hole B16 and coated by the atomized coating material fluid formed by the first spray component C2 and the second spray component C4, forming a coated multi-element material. The multi-component material enters the spiral conveyor pipe D3 through the first discharge assembly channel A15. The heating element D4 solidifies and shapes the multi-component material moving from top to bottom in the spiral conveyor pipe D3. During the solidification and shaping process, the gas in the material is evaporated. The solidified multi-component material enters the support collection cylinder D12. Under the action of the external suction device, the solidified multi-component material enters the collection pipe D13 through the collection hole D14 and is collected by the external equipment.
