The utility model relates to a rotary pressing type chewing simulator. The rotary pressing type chewing simulator is characterized by comprising a test cavity which consists of a cylindrical water bath circulating box and an annular water bath circulating box which is arranged around the circulating box, wherein a small bowl which is used for containing artificial saliva and tested objects and has a flat bottom is seated on the cylindrical water bath circulating box; a rotary pressing circular disc connected with a motor rotating shaft extends into the test cavity in a hoisting mode and corresponds to the bowl bottom of the small bowl with the flat bottom; a liquid inlet pipe and a liquid outlet pipe are arranged on two sides of a bowl cavity; and the bottom surface of the cylindrical water bath circulating box is connected with an air cylinder and can be lifted under the action of the air cylinder. By utilizing the rotary pressing type chewing simulator, the constant-temperature environment of oral cavities of human bodies can be simulated, the artificial saliva and smoking cessation chewing gum can be stirred and chewed fully, chewing release saliva can be collected in real time to be analyzed, and the fresh artificial saliva can be replenished automatically in time. The rotary pressing type chewing simulator can simulate the chewing process of the human bodies and meet the study of chewing release behavior of chemical components in gum matrix foods, and can be widely applied to the analytical detection of the simulative chewing process of various chewing foods and medicines.
