Description

Technical Field

[0001] This utility model relates to the field of drying technology, and more specifically, to an animal feed powder drying device. Background Technology

[0002] In the existing technology, an animal feed powder drying device has obvious shortcomings in practical application. These shortcomings are mainly reflected in the difficulty of achieving multi-directional drying inside the chamber and the inconvenience of adjusting the flow rate and velocity of the drying gas, which affects the efficiency and quality of feed drying.

[0003] Firstly, animal feed powder usually requires hot air or other drying gases to uniformly treat the material during the drying process in order to reduce moisture, inhibit mold growth, and ensure the stability of feed storage. However, most existing drying devices adopt a single-direction or fixed airflow path drying method, which leads to uneven airflow distribution inside the chamber. This can easily cause local over-drying and may even affect the nutritional components of the feed. Insufficient airflow in some areas results in incomplete drying of the feed, with a high moisture content, thus leading to poor overall drying effect and affecting the quality and shelf life of the feed.

[0004] Secondly, existing equipment lacks flexibility and convenience in regulating the flow rate and velocity of the drying gas. Traditional equipment typically relies on mechanical valves or simple fan speed adjustments to control airflow. However, this method has limited precision and is cumbersome to operate. For example, when the feed has a high moisture content, the gas flow rate and velocity need to be increased to accelerate moisture evaporation; while when the material is nearing the end of drying, the airflow needs to be appropriately reduced to avoid over-drying and energy waste. However, due to the inconvenience of adjustment, it often fails to adequately meet the drying needs at different stages, resulting in low drying efficiency and increased energy consumption.

The inner support frame 10 pushes the corrugated plate 11 on the inner wall of the regulating pipe 6 inward, changing the cross-sectional area of ​​the regulating pipe 6 and precisely controlling the hot air flow. The paired receiving blocks 13 slide centripetally on the outer fixed ring 12. The receiving spring 28 provides a restoring force, and the ball-embedded block 29 passes between the receiving blocks 13 to ensure the stable rotation of the rotating sleeve 7.

[0030] When the auxiliary mechanism needs to be adjusted, the rotating ring 14 and the pressure ring 15 are respectively installed at the top and bottom ends of the rotating sleeve 7 to provide rotational support. The threaded ring 16 is threaded onto the outer wall of the adjusting tube 6, and the longitudinal sliding ring 17 is longitudinally slidably installed. When the adjustment position needs to be locked, the longitudinal sliding ring 17 moves longitudinally, and the support spring 18 extends into the support groove 19 of the pressure ring 15 step by step and is fixed, so as to firmly lock the rotating sleeve 7 onto the adjusting tube 6 and prevent the adjustment position from being changed accidentally.
