Description

Technical Field

[0001] This utility model relates to the technical field of drum drying equipment, and specifically to a guide drum drying device. Background Technology

[0002] Currently, drum dryers are commonly used in food processing to dry and mature slurries for further processing. However, existing drum dryers consist of a drying cylinder and multiple feeding rollers arranged around its perimeter. Gaps are provided between each feeding roller and the drying cylinder to facilitate slurry flow, allowing the slurry to be dried and matured by the high-temperature drying cylinder. However, before maturation, the slurry is raw, and raw materials have good fluidity, easily flowing outside these gaps, resulting in incomplete drying and maturation.

[0003] Furthermore, in existing drum dryers, the drying cylinder and each feeding roller are connected by multi-stage gear meshing, resulting in slow operating speed and limited gap width adjustment, which in turn leads to low slurry drying and maturation efficiency. Moreover, the multi-stage gear meshing also contributes to the complex structure and difficult maintenance of the drum dryer.

[0004] In summary, there is a need to provide a guide roller drying device to solve the problems of complex structure, difficult maintenance, incomplete drying and maturation of slurry, and low drying and maturation efficiency of existing roller drying equipment. Utility Model Content

The rotation direction of the raw material stirring shaft 2 is opposite to the rotation direction of the first feeding roller, but the same as the rotation direction of the drying cylinder 1 and the second feeding roller. That is, after the raw material enters the feeding gap, with the opposite rotation of the raw material stirring shaft 2 and the first feeding roller, as well as the opposite rotation of the first feeding roller and the second feeding roller, it can be stably guided into the first and second feeding gaps (i.e., the raw material drying and maturation area B, which includes the raw material area (i.e., the dark area is B1) and the raw material semi-matured area (i.e., the light area is B1)). Then, with the help of the directional rotation of the drying cylinder 1 and the heat, the slurry is completely dried and matured.
