Embodiment 1
[0047] This embodiment includes: (1) preparation work, (2) charging, (3) cooling - high temperature constant temperature - cooling - low temperature constant temperature crystallization, (4) heating - constant temperature sweating, (5) crude product collection, (6) product Refining and molding, packaging and other processes.
[0048] (1) Preparation
[0049] Connect the sealing system on the upper part of the sweating dish with the buffer tank and the compressor. A buffer tank is installed on the lower part of the sweat dish and a vacuum pump is connected.
[0050] The lower part of the sweating dish plate is cushioned with water.
[0051] Connect the jacket of the sweating dish with a movable coil and a circulation system with programmed cooling / heating function, using water as the heat transfer medium.
[0052] Start the heating function of the circulation system to raise the temperature of the circulating water medium to 78°C.
[0053] (2) Loading
