● Heat source (for example, low pressure steam or thermal conduct oil) passthrough the sealed jacket. The heat will be transmitted to raw material to bedried through inner shell;
● Under driving of power, the tank is rotated slowly and the raw material inside itis mixed continuously. The purpose of reinforced drying can be realized;
● The raw material exists is under vacuum. The drop of steam pressure makesthe moisture (solvent) at the surface of raw material become saturation and willevaporate. The solvent will be discharged through vacuum pump an recoveredin time. The inner moisture (solvent) of raw material will infiltrate, evaporate anddischarge continuously. The three processes are carried out unceasingly andthe purpose of drying can be realized within a short time.
The natural pollen produced by the 2450MHz, 45KW tunnel type microwave drying and sterilizing machine realizes continuous production, the production efficiency is increased by several times, the power saving is more than 80%, the product quality is good, and the economic benefit is remarkable.
The microwave heating work in the heating -room and waveguide pipe made of metal,which can prevent the leakage of the microwave, radioactivity harmful and discharge of gas.There is no waste heat and dust pollution,so microwave heating neither contaminate food nor pollute the environment.
