Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-8 The present invention provides a technical solution: a double-shaft mixing and kneading device for high-oil and high-sugar dough, comprising a mixing tank body 1, a tank cover 2 that can be opened and closed and buckled up and down is provided on the top of the mixing tank body 1, a main mixing shaft 3 and an auxiliary mixing shaft 4 are respectively provided on both sides of the lower surface of the tank cover 2, which are located in the inner cavity of the mixing tank body 1.

[0028] Further, such as Figure 3As shown, the outer side of the main stirring shaft 3 is evenly distributed with the welding fixed support shaft 7, and the support shaft 7 and the wave-shaped paddle 5 are correspondingly welded with the support rod 8. The support shaft 7 and the support rod 8 play a role in auxiliary fixing and supporting the wave-shaped paddle 5.
