The filtered gas can enter the interior of the insulation pipe through the one-way pipe, and then enter the interior of the return air pipe 46 through the insulation pipe 87, achieving the effect of circulating drying. At the same time, when the user needs to maintain and clean the filter box 81, he can close one of the electric air valves 85, so that the hot air no longer enters the filter box 81 through the closed electric air valve 85.

The rotation of the push plate can push the material. At the same time, the partition plate 18 can separate the material, so that the material can be quantitatively separated and unloaded. At the same time, the inclined plate 19 can facilitate the partition plate 18 to separate and unload during use, thereby enhancing the separation stability of the material.

[0040] The working principle and use process of the present invention are as follows: when in use, the concentrated bucket 51 can concentrate the materials and transport them to the inside of the feed pipe 2, and then by starting the motor 52, the output end of the motor 52 drives the reducer 53 to rotate, and the rotation of the reducer 53 can drive the unloading ring 54 to rotate. Under the influence of gravity, the rotating materials of the unloading ring 54 can fall through the unloading chute 55 to the inside of the connecting groove 57 on the support ring 56 for quantitative unloading, which can avoid the situation where too much material falls at the same time, resulting in the wind force delivered by the fan 42 being unable to drive the material to move. At the same time, the quantitative unloading of multiple batches of materials also helps to quickly heat and dry the materials, and then by starting the heating ring 61, the heating ring 61 outputs heat the outer side of the drying tube 44, and the heating wire can be started at the same time. 63, so that the heating wire 63 heats the inner side of the drying tube 44, so that the temperature in the drying tube 44 rises rapidly. When the temperature in the drying tube 44 is preheated, the temperature in the drying tube 44 can be detected by the temperature sensor 11. After the temperature reaches a suitable range, the fan 42 is started so that the suction end of the fan 42 sucks the wind in the return air duct 46, and then the wind is transported to the inside of the connecting tube 43 through the output end. After the wind passes through the connecting tube 43, it can enter the inside of the drying tube 44 and drive the material dropped from the feed pipe 2 into the drying tube 44 to move, so that the material is quickly transported and moved in the drying tube 44. After the material is heated and dried in the drying tube 44 and enters the conveying pipe 45, the electromagnetic valve 73 can be started to open the first The one-way valve 72 is connected to the conveying pipe 45. The material enters the interior of the rotary separator 71 through the solenoid valve 73 and the first one-way valve 72 under the conveyance of wind. After the rotary separator 71 rotates and separates the material, the material can enter the interior of the limiting groove 75. The collecting box 76 can collect the material in the interior of the limiting groove 75. The limiting plate 74 can limit the collecting box 76 through the limiting groove 75, so that the collecting box 76 can stably collect the material in a concentrated manner to achieve the effect of continuously circulating and drying the material. At the same time, the hot air separated from the rotary separator 71 can enter the interior of the collecting pipe 82 through the rotary separator 71, and then enter the interior of the collecting pipe 83 through the collecting pipe 82, and finally enter the interior of the connecting pipe 84 through the collecting pipe 83. At this time, the user can open the electric air valve 85, so that the electric air valve 85 opens the connection between the connecting pipe 84 and the filter box 81, so that the gas can enter the filter box 81 for filtration, and the filtered gas can enter the inside of the heat-insulating pipe through the one-way pipe, and then enter the inside of the return air pipe 46 through the heat-insulating pipe 87, thereby achieving the effect of circulating drying. At the same time, when the user needs to maintain and clean the filter box 81, he can close one of the electric air valves 85, so that the hot air no longer enters the filter box 81 through the closed electric air valve 85. The user can edit the maintenance and cleaning of the filter box 81 with the closed electric air valve 85. At the same time, since the filter box 81 is provided with several groups, the normal filtering use of the hot air will not be affected during the maintenance of the filter box 81.The return air duct 46 can circulate the filtered hot air to the suction end of the fan 42, which is convenient for the fan 42 to output wind force stably, and at the same time saves a certain amount of heating energy, so that the fan 42 can deliver wind force to the heat in the drying tube 44, and at the same time can quickly heat and dry the material. At the same time, the insulation board 64 can insulate the outer side of the continuous circulation drying 1 to reduce the loss of heat from the continuous circulation drying 1. At the same time, the vacuum insulation board 65 can vacuum insulate the outer side of the insulation board 64 to isolate the outer side of the insulation board 64 from the external temperature, reducing the loss of temperature in the continuous circulation drying 1. The protective board 66 can protect the outer side of the vacuum insulation board 65, enhance the safety of the use of the vacuum insulation board 65, avoid the situation where the vacuum insulation board 65 is damaged and cannot be vacuum insulated, and enhance the use effect of the drying device.

[0041] To sum up: this circulating drying device for yeast powder production quantitatively transports, heats and dries the material through the quantitative unloading mechanism 5 and the heat preservation and heating mechanism 6 in cooperation with the connecting circulation mechanism 4, and then separates and stores the dried material from the conveying wind through the collecting and taking-out mechanism 7, and then filters the drying wind through the multi-layer filtering mechanism 8 and circulates it. This solves the problem that when drying yeast powder in the existing drying device, a part of the wet yeast powder needs to be put into the drum for drying treatment first, and yeast powder can only be put in again after the yeast powder is dried and taken out, which results in discontinuous drying of the yeast powder and cannot adapt to the assembly line production of yeast powder, causing inconvenience in use and reducing the use effect of the drying device.

[0042] Based on the above-mentioned circulating drying device for producing yeast powder, an embodiment of the present invention further provides a drying method for drying yeast powder. Exemplarily, the drying method includes: Start the connecting circulation mechanism, heat preservation and heating mechanism, quantitative feeding mechanism, collection and removal mechanism and multi-layer filtering mechanism; The quantitative unloading mechanism stores the materials centrally, and after starting, it transports the materials to the feeding pipe in batches at regular intervals for quantitative unloading; The connected circulation mechanism starts the conveying wind force to pneumatically convey the material falling in the discharge pipe; The heat preservation and heating mechanism starts to heat the wind and materials conveyed by the connected circulation mechanism, so that the materials are quickly heated and dried during the conveying process; The collection and removal mechanism is activated to separate the dried material from the conveying wind, and conveniently collect and store the material; The multi-layer filtering mechanism starts circulating filtering of the separated wind, and transmits the filtered wind to the connecting circulation mechanism for circulating transmission.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
