The forming machine body 1 includes two sets of forming molds 11 arranged in pairs. The two sets of forming molds 11 rotate relative to each other, forming a compression zone between them for extruding biomass fuel. The biomass fuel extruded by the two sets of forming molds 11 forms pellet fuel and is discharged. The feeding assembly 2 is connected to the forming machine body 1 and has a conveyor belt 21 that continuously feeds biomass fuel into the compression zone of the forming machine body 1. The feeding assembly 2 is used to continuously feed biomass fuel into the forming machine body 1. The screening assembly 3 is located on one side of the forming machine body 1 and is used to receive the extruded biomass fuel pellets and screen them. The control assembly 4 is connected to the side of the forming machine body 1 and is electrically connected to the forming machine body 1, the feeding assembly 2, and the screening assembly 3, and is used to control their operation respectively.

Compared with the prior art, by adding a feeding component 2 and a screening component 3 to the forming machine body 1, the feeding component 2 can continuously feed biomass fuel into the forming machine body 1, realizing continuous production of the forming machine body 1. Moreover, the screening component 3 can screen and filter the formed biomass fuel pellets, so as to facilitate the grading, screening and classification of the biomass fuel pellets for use.

The entire process does not require manual conveying or adding of biomass fuel, realizing automatic feeding and automatic processing and molding, and improving processing and molding efficiency.

[0038] In this embodiment, the forming machine body 1 can be a conventional double-roll forming machine. Through the relative extrusion of two sets of forming molds 11, multiple forming holes are evenly distributed along the circumference of the two sets of forming molds 11. The biomass fuel is extruded and discharged from these forming holes, and the discharged biomass fuel is processed into biomass fuel pellets. This enables continuous and automated production of biomass fuel pellets.
