[0002] Plate pulse vacuum dryer achieves dehydration and drying operations through vacuum, heating and pulsed gas pumping, and is often used in the processing of medicinal materials, health products and other fields.

[0003] At present, plate-type pulse vacuum dryers mostly use heating tubes, which are arranged in a curved manner and have high-temperature water circulating inside to heat the medicinal materials in the tray on the heating tubes.

[0004] During the application process, it was found that the temperature of the medicinal materials directly above the heating tube was higher after heating, while the temperature of the medicinal materials away from the heating tube was relatively lower after heating. That is, the medicinal materials in the same tray were heated unevenly, and the medicinal materials directly above the heating tube were overheated, while the medicinal materials in other areas were not heated enough. Therefore, it is not conducive to the control of the medicinal properties during the processing of the medicinal materials, and some of the medicinal properties are destroyed. Utility Model Content

[0025] The heating plate 4 also includes a heat conducting plate 43, which is a metal plate. Multiple heat conducting plates 43 are horizontally fixed between the heating tube 41 and the heat spreader 42. The heat conducting plate 43 is connected to the heating tube 41 and the heat spreader 42, and multiple heat conducting plates 43 are evenly arranged below the heat spreader 42.

[0026] The heating plate 4 also includes a heat-conducting side plate 44, which is a metal plate. Multiple heat-conducting side plates 44 are vertically arranged below the heat-conducting plate 43, and multiple heat-conducting side plates 44 are arranged in sequence along the extension direction of the heating tube 41. The heat-conducting side plates 44 are respectively connected to the heating tube 41 and the corresponding heat-conducting plate 43.

[0029] The specific operation process of this utility model is as follows:

[0030] In the present invention, a hot water source is provided outside the housing 1 and can be a heating boiler or an air-to-air heat pump. The hot water source is connected to the water inlet ends of a plurality of heating pipes 41. A circulating pump is provided between the heating pipes 41 and the hot water source. The water outlet ends of the heating pipes 41 are connected to a water storage tank, which in turn is connected to the hot water source.

[0031] Each heating tube 41 is bent, and the intervals between the bent heating tubes 41 are the same. The heating tube 41 transfers heat to multiple heat-conducting side plates 44. The extension direction of the heat-conducting side plates 44 on the horizontal plane is perpendicular to the direction of the straight-line arrangement portion of the heating tube 41. The heat-conducting side plates 44 are evenly arranged.

[0032] Each heat conducting plate 43 is connected to a plurality of heat conducting side plates 44, which can conduct the heat on the heat conducting side plates 44 to the heat conducting plate 43. Since the heat conducting side plates 44 are evenly and densely distributed, the heat can be evenly transferred to the heat conducting plate.

[0033] Multiple heat conducting plates 43 are evenly arranged below the heat spreader 42. The heat on the heat conducting plates 43 is relatively evenly distributed. When the heat conducting plates 43 transfer heat to the heat spreader 42, the heat can be further evenly distributed on the entire heat spreader 42. In this way, the heating plate 5 is heated evenly, the medicinal materials inside the heating plate 5 are heated evenly, and the processing quality is stable and reliable.
