Description

Technical Field

[0001] The invention belongs to the technical field of feed expansion, and in particular relates to drying equipment for feed expansion. Background Art

[0002] Extruded feed is a pellet feed processed by extrusion technology. When the feed is squeezed out of the die hole under great pressure, the temperature and pressure drop suddenly because it suddenly leaves the body and enters the atmosphere, causing the water in the feed to evaporate quickly and the volume of the feed to expand rapidly. In addition to the general advantages of pellet feed, it also has better palatability, higher digestibility, and variable appearance. It can be made into floating or sinking feed, and can effectively sterilize and remove toxins. The expanded feed will enter the drying stage. There is some powder in the expanded pellet feed. In order to ensure the quality of subsequent feed, it is necessary to screen the pellets and powder. The current screening stage usually feeds the dried feed after unloading, and then puts it into the screening mechanism again, which will cause inconvenience in the handling and transfer of the feed, increase the production process of the feed, extend the production cycle of the feed, and bring inefficiency to the production and processing of the feed. At the same time, it is not convenient to collect and clean the feed powder that is screened, which increases the tediousness and inconvenience of subsequent manual cleaning.

At this time, the operation of the heating wire 1022 will generate heat, and at this time, in conjunction with the operation of the fan 1028, the external air is drawn into the three-way pipe 1027, and then through the arrangement of the pipeline 1024 and the connecting pipe 1025, it evenly comes to the multiple air outlet openings 1026, and the air blown out of the air outlet openings 1026 will be blown to the filter conveyor belt 2014 with heat, thereby realizing the drying process. The operation of the rotating motor 1 2019 will drive the rotating rod 1 2011 and the roller 2013 on the surface of the rotating rod 1 2011 to rotate, wherein the setting of the filter conveyor belt 2014 will realize the synchronous rotation of the two rollers 2013, thereby realizing the rotation of the rotating rod 2 2012, wherein the feed on the surface of the filter conveyor belt 2014 will be transported and delivered, realizing the transportation and drying of the feed.
