[0024] In order to achieve the effect of multiple drying, the heating bin 12 in this embodiment is provided with a first hot air duct 14, a second hot air duct 15 and a third hot air duct 16, the other end of the first hot air duct 14 is fixedly connected to the first drying bin 3, the other end of the second hot air duct 15 is fixedly connected to the second drying bin 4, and the other end of the third hot air duct 16 is fixedly connected to the material receiving bin 5; during the use of this connection mode, when the staff controls the fan 11 to generate airflow and heats it under the action of the heating bin 12, it can be sent to the first drying bin 3, the second drying bin 4 and the material receiving bin 5 through the first hot air duct 14, the second hot air duct 15 and the third hot air duct 16, the wet yeast first passes through the first drying bin 3 for a primary drying, then is sent to the second drying bin 4 for a secondary drying, and finally falls into the material receiving bin 5 for a third drying effect;

[0025] This method can effectively ensure the effect of drying the wet yeast multiple times during use, avoiding poor drying effect and agglomeration due to uneven heating.

[0026] In order to achieve the effect of breaking up the wet yeast, a support rod 52 is rotatably connected in the receiving bin 5 in this embodiment, and the support rod 52 passes through the second drying bin 4 and the first drying bin 3. A wind wheel 55 is arranged on the top of the support rod 52, and a first auger blade 53 and a second auger blade 54 are arranged on the rod body of the support rod 52.

[0027] As a preferred technical solution in this embodiment, in actual use, the staff can pass the wet yeast from the heat recovery component 2 into the first drying chamber 3. At this time, the fan 11 can be started to generate airflow, and then the airflow heated by the heating chamber 12 can enter the first drying chamber 3 to dry the wet yeast. At this time, the airflow can drive the wind wheel 55 to rotate.

This method can effectively ensure that it can be dried more thoroughly during use and avoid the occurrence of agglomeration.

[0028] Embodiment 2:

[0029] See also Figure 4 In order to achieve the effect of heat recovery of the waste gas after drying, the heat recovery component 2 in this embodiment is provided with a preheating bin 21, and a heat recovery pipe 22 is provided at the bottom of the preheating bin 21, and the other end of the heat recovery pipe 22 is connected with the first drying bin 3. The heat recovery pipe 22 is provided to collect the waste gas generated by the first drying bin 3 after drying during use, so that the waste gas can enter the preheating bin 21 through the heat recovery pipe 22 to preheat the wet yeast to be dried, further increasing its drying effect.

[0030] In order to achieve a good feeding effect, a feeding pipe 23 is provided at the bottom of the preheating bin 21 in this embodiment, and the other end of the feeding pipe 23 is connected to the first drying bin 3, and a suction machine 24 is provided on the feeding pipe 23.

[0032] As a preferred technical solution in this embodiment, during the process of drying the wet yeast, the waste gas generated during the drying process will enter the preheating bin 21 through the heat recovery pipe 22 for heat recovery, thereby ensuring that it can preheat the yeast. In addition, under the action of the connecting pipe 51, the drying waste gas from the receiving bin 5 and the second drying bin 4 can be passed into the first drying bin 3, and then passed into the preheating bin 21 through the heat recovery pipe 22 to achieve the effect of heat recovery.

[0033] Furthermore, in order to enhance the effect of heat energy recovery, an exhaust fan can be added to the heat recovery pipe 22 to ensure its absorption efficiency of exhaust gas. In order to further achieve the effect of adsorbing water vapor in the drying exhaust gas, an activated carbon water absorption layer can be set inside the heat recovery pipe 22.

[0034] The working principle of the above embodiment is:

[0035] 1. The staff can pass the wet yeast from the heat recovery component 2 into the first drying chamber 3. At this time, the fan 11 can be started to generate airflow, and then the airflow heated by the heating chamber 12 can enter the first drying chamber 3 to dry the wet yeast. At this time, the airflow can drive the wind wheel 55 to rotate. During the rotation of the wind wheel 55, the wet yeast can be dispersed to ensure that it can be heated more evenly during the drying process. At the same time, during the rotation of the wind wheel 55, the support rod 52 can be driven to rotate the second auger blade 54 and the first auger blade 53. During the rotation of the second auger blade 54, the wet yeast that has been dried once can be transferred to the second drying chamber 4 for secondary drying. After the second drying chamber 4 is dried twice, the wet yeast will fall into the receiving chamber 5 under the action of the first auger blade 53 for the third drying effect. This method can effectively ensure that it can be dried more thoroughly during use and avoid the occurrence of agglomeration.

[0036] 2. During the process of drying the wet yeast, the waste gas generated during the drying process will enter the preheating bin 21 through the heat recovery pipe 22 for heat recovery, thereby ensuring that it can preheat the yeast. In addition, under the action of the connecting pipe 51, the drying waste gas from the receiving bin 5 and the second drying bin 4 can be passed into the first drying bin 3, and then passed into the preheating bin 21 through the heat recovery pipe 22 to achieve the effect of heat recovery.
