The circulation of the hot air in the installation chamber 81 is achieved.
In another embodiment, the air outlet of the air supply duct 1 is located in the installation chamber 81, the air inlet of the air return duct 3 is located in the installation chamber 81, and the air outlet of the air return duct 3 extends to the air inlet of the air heater 2.
In another embodiment, a temperature sensor is arranged in the grease conveying pipeline 8, so that the temperature sensor can detect the temperature in the grease conveying pipeline 8 conveniently, the temperature is controlled within a preset temperature range all the time, and the influence of too low temperature on the fluidity of phospholipid molecules is avoided.
The specific working principle is as follows:
the preparation of liposomes is exemplified. In winter or use in the north, when starting liposome extruder, start air heater 2 in advance, air heater 2 works and will hot-blast drum into installation cavity 81 and air supply pipe 1 in, preheat grease pipeline 8, preheat in the back grease gets into grease pipeline 8, because grease pipeline 8 has certain heat, reduce the condition that the caking appears in the grease in transportation process, if there is the grease of caking to be cut by the branch cutting net 4 that sets up in grease pipeline 8 in transportation process, then melt fast through the heated air circulation heat transfer again, avoid blocking grease to adhere to on the inside wall of grease pipeline 8. Because the slitting net 4 is woven by metal wires drawn from pure gold, the slitting net has extremely high corrosion resistance and good heat conduction performance, and can conveniently and quickly slit blocky grease.
For convenient cubic grease is cut by cutting net 4 fast, the size that is located cutting net 4 of grease conveying pipeline 8 increases progressively in proper order from the feed liquor end one end of grease conveying pipeline 8 towards going out the liquid end, and the grease that conveniently has just agglomerated is cut by cutting net 4, and the mesh that is located going out the liquid end is greater than the mesh of feed liquor end for convenient grease gets into in subsequent processing apparatus fast.
