Description
Technical Field

Background
Macleaya cordata R (Wild) of Papaveraceae is perennial herb with the height of 1-2 m, white powder is on the surface of the plant, and yellow juice flows out after the stem and leaf are broken. The stem is cylindrical, hollow, green, and sometimes reddish purple. The single leaf grows alternately, is wide and oval, has irregular wavy teeth and splinters, is green and smooth in leaf surface, white in leaf back and covered with dense fine hair. White flower, inverted egg-shaped and oblong capsule, flat and red, and 4-6 seeds.
The stem, leaf and fruit of Macleaya cordata all contain alkaloid. The content of these alkaloids varies in the individual organs of the plant. The experimental result shows that the alkaloid content in the aerial parts of the macleaya cordata plants in the same growth period and the same planting area is fruit, leaf and stem. In Zhejiang, 7-11 months are the time of the seed of the Macleaya cordata. At this stage, macleaya cordata fruits should be harvested for extraction of their alkaloids. The alkaloid content in each organ of the wild macleaya cordata plant is higher than that of the wild macleaya cordata plant. Therefore, the macleaya cordata alkaloid product with higher dosage is required to be harvested in wild, classified and stored in different classification frames for being processed by a freeze dryer.
The vacuum freeze-drying machine needs pre-freezing, then sends the material into the drying chamber for vacuum drying, and simultaneously the pumped water vapor is captured in the cold trap until the material reaches a certain equilibrium moisture content. Microwave vacuum freeze-drying includes two main processes of pre-freezing and drying, as well as conventional vacuum freeze-drying. The pre-freezing means that the materials are pre-frozen to be below the eutectic point of the materials, and the water is completely frozen. The pre-freezing process has great influence on the whole microwave vacuum freeze drying, and the difference of the pre-freezing speed can influence the size, the quantity and the distribution of material ice crystals, thereby influencing the freeze-drying time and the quality. The importance of the pre-freezing process to the microwave vacuum freeze drying is explained, but in the design of a plurality of vacuum freeze drying pilot-plant devices at present, the device is usually a simple drying part device only designed for vacuum freeze drying, and the device of the pre-freezing part is omitted, so that a user is forced to use other freezing equipment only, and the pre-freezing process is influenced inevitably, and the whole vacuum freeze drying is influenced. Therefore, the design of the prefreezer is a practical technology which is inevitably solved by the vacuum freeze drying device.
