When the material needs to be loaded after the cleaning is completed, the solenoid valve 306 is first closed and the automatic valve 608 is opened. At this time, the suction force in the air pressure box 303 is transmitted to the inside of the loading barrel 601 through the exhaust pipe 607, and the inside of the loading barrel 601 can be The gas is drawn away, which can then generate suction inside the loading barrel 601, and then the freeze-dried fruit particles in the cleaning barrel 201 are drawn into the loading barrel 601 through the feeding pipe 603, the feeding bottom pipe 604, the feeding seat 605 and the feeding port 606. When the amount of material inside the loading barrel 601 reaches the detection amount, the valve 602 is opened, and the fruit particles enter the guide hopper 8 through the funnel 7, and then enter the multifunctional particle size and particle shape analyzer 1 through the guide hopper 8 for detection.

[0027] Working principle: Before measuring the particle size of freeze-dried fruit, first put the freeze-dried fruit particles through the pipe on the top of the cleaning barrel 201, then start the dust collection mechanism 3. After the dust collection mechanism 3 is started, the gas enters the interior of the installation cylinder 204 through the air inlet pipe 221. At this time, due to the entry of gas, the impeller 205 can be driven to rotate, and the rotation of the impeller 205 can drive the rotating disk 206 to rotate. After the rotating disk 206 rotates, it can drive the air ring 207 to rotate. The gas inside the installation cylinder 204 is passed into the interior of the fixed shell 210 by connecting the ventilation pipe 220, and then the fan blade 217 can be blown. , the fan blades 217 drive the rotating circle 211 to rotate, so that the rotating top ring 212 can be driven to rotate, so the air nozzle 214 installed on the rotating top ring 212 and the top of the air ring 207 will rotate, and the rotation directions are opposite. At this time, the gas is introduced into the interior of the air ring 207 through the vent holes 216 and the ventilation connecting pipe 215. Therefore, when the gas enters the interior of the fixed shell 210 and drives the fan blades 217 to rotate, the gas can also be ejected through the air nozzle 214. The ejection of gas can turn over the freeze-dried fruit particles in the cleaning barrel 201, and the dust on the fruit particles can also be blown away; After the air pump 301 is started, the air inside the air pressure box 303 can be sucked out through the air extraction connecting pipe 302, and the air can be passed into the interior of the installation cylinder 204 through the air inlet pipe 221. When the air in the air pressure box 303 is lacking, suction will be generated inside the air pressure box 303. At this time, the solenoid valve 306 is opened, and the air in the dust box 304 can be sucked out through the connecting pipe 305. Then, the dust in the cleaning barrel 201 can be sucked into the interior of the dust box 304 through the dust extraction pipe 307, thereby realizing automatic cleaning of dust. When the air pressure in the air pressure box 303 is too low, the bottom plate 405 will be sucked downward, and then the tension spring 406 will be stretched, and the sliding tube 403 will slide downward. When the air leakage hole 404 on the sliding tube 403 moves to the inside of the base tube 401, the external air can be sucked into the air pressure box 303 through the sliding tube 403 and the air leakage hole 404, so as to prevent the air pressure in the air pressure box 303 from being too low. When loading is required after cleaning is completed, first close the solenoid valve 306 and open the automatic valve 608. At this time, the suction in the air pressure box 303 will be transmitted to the inside of the loading barrel 601 through the exhaust pipe 607. At this time, the gas inside the loading barrel 601 can be extracted, and then suction can be generated inside the loading barrel 601. The freeze-dried fruit particles in the cleaning barrel 201 are drawn into the loading barrel 601 through the feed pipe 603, the feed bottom pipe 604, the feed seat 605 and the feed port 606. When the inside of the loading barrel 601 reaches the detection amount, open the valve 602, and let the fruit particles enter the inside of the guide hopper 8 through the funnel 7, and then enter the inside of the multifunctional particle size and particle shape analyzer 1 through the guide of the guide hopper 8 for detection.
