The device is to concentrate the material in the occasions such as china traditional drug 、 west drug 、 dextrose 、 amylum sugar 、 oral liquid 、 chemisty 、 foodstuff 、 monosodium glutamate and milk product and to reclaim the industrial organic solvent such as alcohol . it is suitable to concentrate the thermal sensitive material under lower temperature and vacuum with little batch number and multiple varieties 本设备适用于中药、西药、葡萄糖、淀粉糖、口服液、化工、食品、味精、乳品等物料浓缩与工业有机溶剂(如酒精)的回收，适用于批量小、品种多的热敏性物料的低温真空浓缩。
The biological characteristics of mycelia from phellinus igniarius and culture media were studied . two kinds of culture media were suitable for the growth of mycelia . the result indicated that the culture medium with potato as nitrogen source and saccharose as carbon source was suitable for collecting mycelia, and the culture medium with peptone as nitrogen source and solvable amylum as carbon source was suitable for conservation 为了最大限度地保存菌种的活力，以提高菌丝体的质量及菌丝体内活性成分的累积，本文通过对比研究，进一步对其生长基质进行筛选，明确了两种适于桑黄菌丝生长的固体培养基：以马铃薯为氮源、蔗糖为碳源的培养基较适用于菌丝收集，以蛋白胨为氮源、可溶性淀粉为碳源的培养基较适用于菌种的保藏。
The biochemical reaction in liquor-making mainly included the degradation of macromolecular substances such as the degradation of amylum and protein, the biochemical changes of micromolecular substances such as glycolysis of glucose ( emp approach ) and reconvertion of pyruvic acid, and the formation of flavoring substances such as the production of higher organic alcohol, maillard reaction, and the formation of aromatic compounds 白酒酿造过程中的生物化学反应主要包括：大分子物质的降解，如淀粉的降解和蛋白质的降解；小分子物质的变化，如葡萄糖的酵解（emp途径）和丙酮酸的再转化；香味物质的生成，如高级有机醇生成、美拉德反应和芳香族化合物的形成。
The peak times of amylase, cmc enzyme, cellulose, laccase, guaiacol oxidase and polyphenol oxidase were the 10th day, the 12th day, the 12th day, the 14th day, the 16th day and the 16th day respectively . it indicated that phellinus igniarius has the capability of discomposing amylum, cellulose and lignose 淀粉酶、cmc酶、纤维素酶、漆酶、愈创木酚氧化酶、多酚氧化酶的活性高峰分别出现在第10d、第12d、第12d、第14d、第16d、第16d，说明桑黄对淀粉类物质、纤维素类、木质素类物质均具有降解能力。
