Embodiment
[0025] Embodiment: A vacuum freeze-drying device based on intelligent temperature control is composed of a cold flow chamber 10, a temperature compensation chamber 20, a vacuum freeze-drying chamber 40, and an assembly chamber 30. The temperature compensation chamber 20 is set around the side walls of the vacuum freeze-drying chamber 40. The cold flow chamber 10 is set around the side walls around the temperature compensation chamber 20, and the assembly chamber 30 is set at the bottom of the vacuum freeze-drying chamber 40; the cold flow chamber 10 is provided with two sets of vacuum circulation pumps 11, S-shaped cold flow pipes 12 and cold flow medium 13. Two sets of vacuum circulation pumps 11 are respectively connected to both ends of the S-shaped cold flow pipe 12, and the cold flow medium 13 is filled in the cold flow chamber 10, and the filling amount is two-thirds of the volume of the cold flow chamber 10, And through two sets of vacuum circulation pumps 11 to achieve ...

The invention discloses a vacuum freeze-drying device based on intelligent temperature control. The vacuum freeze-drying device based on intelligent temperature control comprises cold flow chambers, temperature compensation chambers, a vacuum freeze-drying bin and an assembly chamber, wherein the temperature compensation chambers are arranged around the side walls of the periphery of the vacuum freeze-drying bin; the cold flow chambers are arranged around the side walls of the periphery of each temperature compensation chamber; the assembly chamber is arranged at the bottom of the vacuum freeze-drying bin; two sets of vacuum circulation pumps, an S-type cold flow tube and a cold flow medium are arranged in each cold flow chamber; a double-stage air compressor is arranged on each temperature compensation chamber; a freezing evaporator, a temperature regulating system and an exhaust valve are arranged in each temperature compensation chamber; freezing interlayers are arranged on the sidewalls of the vacuum freeze-drying bin; a vertical and downward diversion trench is arranged on the side walls of the freezing interlayers; a water collecting tank is arranged on the bottom of the side walls of the freezing interlayers; and a heating tank and a water catcher are arranged in the assembly chamber. The vacuum freeze-drying device based on intelligent temperature control has a novel structure, effectively ensures the uniformity of the distribution of cold and heat in a vacuum freezing cabinet, and ensures that water vapor is not generated in the freeze-drying process.
Description
technical field [0001] The invention relates to a vacuum freeze-drying device based on intelligent temperature control, belonging to the technical field of vacuum freeze-dryers. Background technique [0002] Vacuum freeze dryer is suitable for drying materials such as high-grade raw materials, traditional Chinese medicine decoction pieces, biology, wild vegetables, dehydrated vegetables, food, fruits, chemicals, and pharmaceutical intermediates. In the process of freeze vacuum drying, no impurities are mixed into the object, and the original and active ingredients of the material and the shape of the material are not damaged. The working principle of the vacuum freeze dryer is to put the material into the material box for freezing after starting up. The freezing process of the material: on the one hand, the vacuum system vacuumizes to take away part of the water; on the other hand, when the material is frozen, some The water contained in the molecule is discharged to the su...
