Embodiment 1
[0061] This embodiment includes three parts: (A) preparation of low melting point components, (B) preparation of high melting point components and (C) blending.
[0062] A) Preparation of low melting point components
[0063] This part includes four steps: (A1) preparation, (A2) crystallization, (A3) heating-constant temperature sweating, (A4) refining.
[0064] (A1) Preparations
[0065] Connect the sealing system of the sweating dish with the pressurized buffer tank and the compressor; install the decompression buffer tank and connect the vacuum pump at the lower part of the sweating dish; connect the jacket of the sweating dish and the movable coil with the circulation system, and fix the coil in the On the sweating dish; use water as the heating medium; start the heating function of the circulation system to raise the temperature of the circulating water to 63°C. Put water under the sweating dish plate.
