Device for detecting food mechanical characteristics by simulating human jaw movement circulation

Abstract

The invention discloses a device for detecting food mechanical characteristics by simulating human jaw movement circulation. The device comprises a support, a bionic lower jaw, bionic teeth, a bionic upper jaw, a fixed ejector rod, a rotary shaft, a sleeve, a stepping motor and a rotary body. The stepping motor is installed on the top of the support. The movement of an output shaft of the stepping motor is transferred to the rotary shaft, the bionic upper jaw is driven by the rotary shaft to rotate, the sleeve is fixed to the support, the bionic lower jaw is fixedly connected to the sleeve, the rotary shaft penetrates through the bionic lower jaw to be connected with the bionic upper jaw, the bionic teeth are installed on the bionic upper jaw, the fixed ejector rod is fixed to the bionic lower jaw, the rotary body is fixedly connected with the rotary shaft, and the upper end of the rotary body makes contact with the lower end of the fixed ejector rod. The device for detecting the food mechanical characteristics by simulating human jaw movement circulation is ingenuous and simple in structure, low in cost, high in measurement accuracy, capable of meeting food mechanical requirements, and capable of being used for measuring the food mechanical characteristics.

Description

technical field [0001] The invention relates to a device for detecting mechanical characteristics of food in a cycle imitating human teeth and jaw movement. Background technique [0002] There is a close relationship between the mechanical properties of food and its quality. At present, the main method to evaluate the mechanical properties of food is the instrument evaluation method. The chewing action of the human mouth is simulated by the texture analyzer, and the food is chewed and compressed twice. Although the texture analyzer can be used It is used to evaluate the mechanical properties of food, but in terms of movement form, it is very different from human chewing movement. Human chewing movement is completed by moving the mandible downward and moving to the left and right. Only the force in the vertical direction is applied to the material. In view of the fact that the texture analyzer cannot accurately reflect the mechanical properties of the food, the patent of the ...

[0002] There is a close relationship between the mechanical properties of food and its quality. At present, the main method to evaluate the mechanical properties of food is the instrument evaluation method. The chewing action of the human mouth is simulated by the texture analyzer, and the food is chewed and compressed twice. Although the texture analyzer can be used It is used to evaluate the mechanical properties of food, but in terms of movement form, it is very different from human chewing movement. Human chewing movement is completed by moving the mandible downward and moving to the left and right. Only the force in the vertical direction is applied to the material. In view of the fact that the texture analyzer cannot accurately reflect the mechanical properties of the food, the patent of this invention proposes a food mechanical property detection device that imitates the circulation of human teeth and jaws.
