[0002] Feed processing technology includes batching, mixing, crushing, mixing, puffing, granulation and finished product packaging. Feed puffing refers to the process of placing feed in a high temperature and high pressure environment by physical means and releasing the pressure instantly, so that the water inside the feed evaporates instantly and forms a porous fluffy structure. Feed puffing can improve the physical properties, nutritional value and digestibility of feed. The puffing process of feed generally occurs at the outlet mold of the puffing equipment. After the pressure is released instantly at the outlet mold, the steam inside the feed will expand rapidly, so that the volume of the feed increases rapidly and forms a porous structure. The size of the outlet mold will affect the puffing degree of the feed. Different animals and animals raised at different times have different requirements for the puffing degree of feed. Therefore, puffing equipment is required to process feeds with different puffing degrees. However, when the puffing degree of the current puffing equipment needs to be changed, it is often necessary to disassemble the outlet mold and replace it with a new outlet mold, which is inefficient and cumbersome to disassemble. Frequent disassembly will also affect the sealing of the puffing equipment, thereby affecting the high temperature and high pressure puffing of the internal feed. Utility Model Content
