[0023] As shown in Figure 3 As shown, the top opening of the dehydration tank 6 is provided with an inwardly recessed interlayer, the interlayer of the dehydration tank 6 is used to fit and support the cover plate 5 of the soaking frame 51, the top edge of the dehydration tank 6 is provided with a sealing ring one 10, the sealing ring one 10 is used to seal the closed baffle 8, the top of the inner interlayer of the dehydration tank 6 is provided with a sealing ring two 11, the sealing ring two 11 is used to seal the cover plate 5, so that the soaking frame 51 placed in the dehydration tank 6 remains sealed, reducing the influence of external factors on the dehydration of pathological tissues.

[0024] As shown in Figure 1 and Figure 3 As shown, the leftmost group of dehydration tanks 6 is not installed with dehydrating agent, the lower compartment of the casing 1 is installed with a vacuum pump 12, the vacuum pump 12 is connected to the leftmost dehydration tank 6 through a vacuum pipe 13, so that the dehydration tank 6 without dehydrating agent maintains a negative pressure state, so that the pathological tissues can quickly evaporate the surface moisture in the negative pressure environment during the preliminary dehydration, improving the efficiency of subsequent dehydration.

[0027] First, the pathological tissue to be treated is placed in the soaking frame 51, which is a multi-layer mesh frame structure to facilitate the penetration of the dehydrating agent. In the initial stage, the motor 9 at the dehydrating tank 6 without ethanol is started, which drives the baffle 8 at this position to open, and then the electric push rod 4 is started, the push rod of the electric push rod 4 is elongated and drives the cover plate 5 and the soaking frame 51 to align and extend into the dehydrating tank 6 at this position, so that the cover plate 5 tightly fits the sealing ring two 11 of the dehydrating tank 6 interlayer, ensuring good sealing between the soaking frame 51 and the dehydrating tank 6, reducing external factor interference, and then the vacuum pump 12 is started, which performs vacuumization on the leftmost dehydrating tank 6 without ethanol, so that the inside maintains a negative pressure state, so that the pathological tissue in the soaking frame 51 can rapidly evaporate the water on the surface of the tissue under low-temperature conditions in a negative pressure environment, achieving preliminary dehydration of the pathological tissue.
