[0035] As people's recognition of healthy lifestyles and traditional Chinese medicine continues to increase, the traditional medicinal materials market is gradually rising. The drying of medicinal materials is an important part of ensuring the quality and efficacy of medicinal materials. Therefore, the medicinal materials drying machine industry has broad market prospects. However, most of the traditional heat sources for drying medicinal materials are coal-fired hot air drying, coal-fired steam drying, electric heating drying, etc., which are highly polluting and energy-consuming, and are contrary to the current national "low-carbon energy-saving" concept. As a newer way to dry medicinal materials, heat pump drying technology can achieve a maximum drying temperature of 75°C, which can adapt to the drying temperature conditions of most traditional Chinese medicines. However, the performance of the heat pump is restricted by climatic and environmental conditions, and the drying effect is not good in cold seasons.

[0036] Based on this, see Figure 1 , Figure 2 and Figure 3 The drying system 1000 provided in the embodiment of the utility model can effectively improve the above-mentioned technical problems.

By adopting the combined heat and power supply unit 200 to provide heat energy to the drying system 1000, electric energy is also provided, which is not limited by power supply, can be used anywhere, and is more energy-saving and environmentally friendly. The circulating fan 500 can make air flow in a certain direction. The circulating fan 500 in this embodiment can cool the hot air in the drying chamber 110 through the condensation recovery device 400, and then circulate and recover the hot air to the heat exchanger 300 at the air inlet 130, thereby realizing the recycling of the gas.

[0039] In order to be more energy-saving and environmentally friendly, the combined heat and power generation machine 200 in this embodiment uses natural gas for energy supply. By heating by burning natural gas, the heating will not be affected by seasonal changes or restrictions in cold regions, and the drying performance of the entire drying system 1000 will be more stable. And the use of natural gas for energy supply will not generate pollution, which is more energy-saving and environmentally friendly. Of course, the combined heat and power generation machine 200 can also use other fuels for energy supply, which is not limited here.
