Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, and more specifically, particularly relates to a black soldier fly feed granulator. Background Art

[0002] Black soldier fly is a saprophytic insect of the family Solenopsis that can feed on livestock excrement and domestic garbage. It is usually used to produce high-value animal protein feed because of its rapid reproduction, wide range of food habits, low feeding cost, and good palatability for animals. In the process of using black soldier flies for feed processing, various raw materials need to be mixed and granulated. To produce granular feed, a granulator is needed to produce various raw materials into granular black soldier fly feed according to the required particle size and shape requirements.

[0003] However, there are various types of granulators in the prior art. For example, utility model patent CN219002979U relates to a granulator for producing black soldier fly insect feed. The utility model has a stirring structure that can clear the lower end of the hopper to avoid blockage and ensure the feeding effect. The motor is used in conjunction with the gear to achieve forward and reverse rotation, thereby changing the rotation direction of the stirring component to achieve different clearing effects.

[0004] Although the granulation device can ensure the unblocking effect of material discharge to complete the granulation work, the granular material after granulation by the device is extruded from the extrusion tube, and the extruded feed particles are of the same size, which narrows the application range of the feed particles and is difficult to meet people's current demand for its use. In order to avoid this phenomenon, it is very necessary to design a black soldier fly feed granulator. Utility Model Content
