[0035] The present application starts the driving motor 401 to drive the first driving gear 402 to rotate, thereby driving the first transmission gear 403 to rotate, and then driving the stirring rod 3 to stir and mix the biofuel. At the same time, the lifting driving assembly 404 drives the permeable plate 301 to move up and down to compress the biofuel in the tank body 2.

[0036] Reference Figure 3 The lifting drive assembly 404 includes: a worm 40401, a worm wheel 40402, a linkage assembly 40403, a second transmission gear 40404 and an annular gear 40405.
