Device for detecting mechanical characteristics of human-like tooth and jaw movement cycle food machinery

Abstract

The invention discloses a food mechanical characteristic detection device imitating human teeth and jaw movement cycle, including a bracket, a bionic lower jaw, a bionic tooth, a bionic upper jaw, a fixed ejector rod, a rotating shaft, a sleeve, a stepping motor and a rotating body, and the stepping motor is installed On the top of the bracket, the motion of the output shaft of the stepping motor is transmitted to the rotating shaft, which drives the bionic upper jaw to rotate. The sleeve is fixed on the bracket, and the bionic lower jaw is fixedly connected to the sleeve. The rotating shaft passes through the bionic lower jaw and the bionic The upper jaw is connected, the bionic teeth are installed on the bionic upper jaw, the fixed ejector rod is fixed on the bionic lower jaw, the swivel body is fixedly connected with the rotating shaft, and the upper end of the swivel body is in contact with the lower end of the fixed ejector rod. The device of the invention imitates human-tooth-jaw circulation cycle food machinery characteristic detection device, which has ingenious and simple structure, low cost and high measurement accuracy, meets the requirements of food machinery, and can be used to measure the mechanical characteristics of food.

Description

technical field [0001] The invention relates to a device for detecting the mechanical properties of food in a human-like tooth and jaw movement cycle. Background technique [0002] There is a close relationship between the mechanical properties of food and its quality. At present, the main method for evaluating the mechanical properties of food is the instrument evaluation method. The texture analyzer simulates the chewing action of the human mouth and chews and compresses the food twice. It is used to evaluate the mechanical properties of food, but it is very different from the human chewing movement in the form of movement. Only the vertical force is applied to the material, since the texture analyzer cannot accurately reflect the mechanical properties of the food, the patent of the present invention proposes a detection device for the mechanical properties of the food in the human-like tooth movement cycle. SUMMARY OF THE INVENTION [0003] The purpose of the present i...

[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.
