The Innovation Research on the Extraction Technology of Ganoderma Lucidum

China is the birthplace of the Chinese Medicine. Ganoderma lucidum as a traditional Chinese treasure with Millenium history of medicinal herbs, its medical and health care functions have come to be known to the general public. With the development of technology, G. lucidum health food ceaseless emerges in large numbers. But G. lucidum health food differs in efficacy, component, and content; health care effect is not the same, for this reason, it is closely related to the extraction technology of G. lucidum (Lin, 2007). Extract of G. lucidum extract objective is to maximize the active ingredient within the material, the extraction process in the heating mode, the relative motion of the solid–liquid twophase state, are easy to lead to different extraction speed and effectiveness. For the G. lucidum health food, choosing the appropriate extraction technology and equipments is the key step to the production. In order to make this process successfully completed, for equipment, the optimization of extraction methods and mode of heating that affect the extraction effect most. This G. lucidum extraction device, which consists of heat extraction device and the installation, the green part is heating medium circulation line, and the red part is extraction circular route. The map is introduced base on oil as the heating medium, water as solvent. The device constituted by six key groups. Its work program is: Extract gets through filters to reach the tubular heat exchanger tube by the effect of gas–liquid mixing pump, and the heat transfer oil driven to reach out at hightemperature under the leading by hot oil circulation pump, the hot and cold liquids in a tubular complete heat exchange in heat exchanger, the heating of the extract re-pump back to the extraction tank, the process is cyclical, exist in the whole extraction process (Wang et al., 2000). The Technical characTerisTics on innovaTive Technology of Ganoderma lucidum exTracT heaTing Technical and innovaTion The application of improving heating method Traditional extraction methods use more heating jacket, it sets jacket in the extraction tank wall, which leads to heat conduction through the partitions to complete the process of heat transfer. Schematic can be seen in the outer layer of the insulating layer, middle layer is heated, the internal is the extract, this time, the heat is always around the material, transfer from the outside to inside slowly, the temperature of the bottom, middle material is too low, the effect of heat transfer is limited, not be extracted completely (Liu and Zhao, 2002). Innovative technology of G. lucidum extraction using tubular heat exchanger, the device structure is different from the traditional heating method. It can be seen on the schematic of the device, it is mainly made of the tubular heat exchanger, heat generating devices, hightemperature oil circulating pump, filtration system, and the corresponding piping components. The outside of tubular heat exchanger is cylindrical, with a number of controls inside, the fluid inside pipe is extract fluid (yellow); outside fluid is heat (red). Hot and cold fluids flow respectively in the opposite direction, relies on their high-temperature circulation pump, so the heat can be exchanged. The dynamic cyclic heating only heat flows through the shell, so the heat transfer will be more efficient (Lixi et al., 2008).
