The freeze dryer 1 is divided into an upper and lower part. The first protective door 2 is rotatably installed on the side of the upper part of the freeze dryer 1, and the second protective door 4 is rotatably installed on the lower part of the freeze dryer 1. A baffle 5 is rotatably arranged in the upper part of the freeze dryer 1. The baffle 5 divides the upper part of the freeze dryer 1 into two parts. The baffle 5 seals the two cavities respectively. Placement barrels 6 are respectively installed on both sides of the baffle 5. The baffle 5 is penetrated by a rotating shaft 7. A rotary rod 8 is rotatably arranged in the freeze dryer 1. The rotary rod 8 penetrates the side wall of the freeze dryer 1. A cone wheel of the bevel gear set 9 is installed at the end of the rotary rod 8. The other cone wheel of the bevel gear set 9 The wheel is installed on the rotating shaft 7, and the two cone wheels are meshed with each other. An identification plate 10 is installed on the outside of the freeze dryer 1. The identification plate 10 is located on both sides of the rotating rod 8 to mark whether it is cooling or heating. A refrigeration component 11 and a heating component 12 are installed on the top of the freeze dryer 1. A protective shell 13 is installed in the upper part of the freeze dryer 1. The protective shell 13 is divided into two cavities with the plane where the baffle 5 is located as the dividing line. The cold air pipe and the hot air pipe are respectively located in the two cavities. A discharge trough 15 is opened at the bottom of the placement barrel 6, and a discharge plate 14 is movably installed at the bottom of the rotating shaft 7. A discharge port is opened on the discharge plate 14, and the discharge plate 14 is movably connected to the discharge trough 15. A control module 24 and a gas detector 23 are installed on the upper part of the freeze dryer 1. An alarm 25 is installed on the top of the freeze dryer 1.

[0024] The freeze dryer 1 is working, and the sulfate esters to be freeze-dried are placed in the two placement barrels 6 respectively. When the gas detector 23 detects that there is gas in the freeze dryer 1, the signal is transmitted to the control module 24, and the control module 24 sends the signal to the alarm 25. The alarm 25 sends an alarm signal. After receiving the signal, the staff starts the refrigeration component 11 to cool the sulfate ester therein. At the same time, the heating component 12 works to dry the sulfate ester therein. When both sides achieve the expected effect, the rotating rod 8 is rotated, and the bevel gear on the rotating rod 8 drives the bevel gear set 9 to rotate, and the bevel gear set 9 drives another bevel gear to rotate, and the other bevel gear drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the baffle 5 to rotate. It is observed through the identification plate 10 that the rotation stops after reaching 180 degrees, that is, the two placement barrels 6 are swapped with each other, the cooled phosphate ester is heated and dried, and the dried phosphate ester is cooled and stored.

Several support seats 21 are installed on the side of the freeze dryer 1, and the exhaust pipe 22 is arranged in the support seat 21.
[0027] When the alarm 25 sounds, the vacuum pump 19 is started to extract the air in the upper part of the freeze dryer 1 through the exhaust pipe 22, thereby exhausting the air in the freeze dryer 1.
[0028] like Figure 1 and Figure 4 As shown, it also includes an observation window 3, a collection frame 16, a handle 17 and a rubber sleeve 18.
