摘要： The disclosure discloses a bionic digestive tract as well as a preparation method and application thereof, belonging to the field of bionic technologies and the field of biological technologies. The bionic digestive tract of the disclosure is prepared by mixing a base material (one or more of silica gel, latex and hydrogel) and auxiliary materials (silicone oil and a curing agent) in a certain mass ratio (the mass ratio of the base material to the silicone oil to the curing agent is 100:(0.5 to 10):(0.5 to 3.5)). The simulation performance of the bionic digestive tract is excellent, has strong consistency with a true human digestive tract in terms of performance, structure and function, can simulate the true states of food, drugs and microorganisms in a digestive system, and has great application prospects in the research process of food and drugs.

摘要： Processes and apparatuses for producing polymer particles with a solid state polycondensation reactor and an underwater pelletization unit. The apparatuses use a pre-conditioning zone to adjust a temperature, crystallization in addition to dust, acetaldehyde and water content of the particles from a crystallization bin. Various inert gas streams can be provided from a purification unit to remove dust, acetaldehyde, water and adjust temperature and crystallinity of the particles, as also move the particles. The precondition zones have stages that allow for the particles to accurately achieve the desired SSP reactor inlet conditions.
