A vibration motor 12 is fixedly connected to the bottom of the support frame 9. The electric heating tape, servo motor 5, and vibration motor 12 are all controlled by the controller 8.

[0021] To effectively dry spirulina in the drying chamber at low temperatures, the pressure-reducing assembly includes a vacuum pump 15, a cold trap 16, and a water absorption box 17. The vacuum pump 15 is fixedly connected to the top of the drying chamber 1. The input end of the vacuum pump 15 is connected to the output end of the cold trap 16 through a connecting pipe. To prevent excess moisture from entering the vacuum pump 15 and affecting its operation, the input end of the cold trap 16 is connected to the drying chamber 1 through a transmission pipe.

The water absorption box 17 is filled with a water absorbent, which is one of molecular sieve, sodium polyacrylate, or activated alumina.

[0022] To reliably pulverize spirulina, the pulverizing assembly includes a motor 13, a rotating shaft 20, a first crushing blade 21, and a second crushing blade 22. The motor 13 is fixedly connected to the outside of the sieving box 2.

After the vacuum degree of the vacuum pump 15 is set by the controller 8, the vacuum pump 15 and the electric heating tape in the jacket 3, rotating shaft 4 and spiral conveyor blades 6 are started to perform depressurization and low-temperature drying of the spirulina in the drying chamber 1. During this process, the humidity in the drying chamber 1 is monitored in real time by the temperature and humidity sensor 7. When the humidity meets the requirements, the discharge valve 18 is opened to allow the dried spirulina to fall into the crushing chamber 10. The motor 13 and the vibration motor 12 are started. The spirulina is crushed to a suitable size by the first crushing blade 21 and the second crushing blade 22 and then falls into the sieve plate 11. During this process, the fan 19 is started to blow up the spirulina that has not fallen into the sieve plate 11 to improve the crushing efficiency of the spirulina. Under the action of the vibration motor 12, the spirulina powder falls into the sieve plates 11 of different mesh sizes in sequence to complete the grading. After the sieving is completed, the equipment is stopped, the door of the sieving box 2 is opened, and the sieve plate 11 is taken out.
