Problems solved by technology

However, the chewing process of actual people is accompanied by the dynamic secretion of saliva and the dynamic swallowing action, that is, the amount of saliva and the concentration of chemical substances dissolved in it are updated at any time, and the existing simulated chewing machines cannot imitate this dynamic update process

Embodiment 1

[0051] Use as attached Figure 6 The chewing machine teeth shown chew gum-based chewing tobacco.

[0052] Put one piece of gum-based chewing tobacco into the solution dish, add 10mL of artificial saliva, and set the chewing mechanical teeth. The working process is as follows: select 5Kg weight assembly 4 and install it on the upper chewing lifting shaft 6, and set it to bite up and down at a frequency of 5 seconds. 20 times, set each chewing action to rotate 180° when the upper chewing lifting shaft drops 20mm to achieve left and right grinding. After biting up and down and rubbing right and left 20 times in this way, the gum-based chewing tobacco was completely broken with the cooperation of another artificial tongue. The solution in the solution dish was drained for main component analysis, and the remaining gum-based chewing tobacco samples were taken out for further analysis and testing.

Embodiment 2

[0054] The full simulation chewing machine of the present invention is used to simulate the chewing process of gum-based chewing tobacco.

[0055] Put a piece of gum-based chewing tobacco into the solution dish, inject 10ml of artificial saliva, set the chewing mechanical teeth to rotate up and down for 20 times at a frequency of once every 5 seconds, start the left and right opening and closing rotating components every 4 times, Rotate 45° to do one bite, the bite width is 15mm, a total of 5 bites. After the extraction is completed, the solution is extracted to the No. 2 collection station. Inject 10ml of artificial saliva for the second time, rotate and chew 10 times at a frequency of once every 10 seconds, start the left and right opening and closing rotating components every 5 times, make a bite every 30° rotation, the bite width is 10mm, and bite 6 times in total. After completion, the solution is extracted to the No. 3 collection station. Inject 10ml of artificial sali...

Abstract

The invention discloses a full simulation chewing machine which comprises a left-and-right opening, closing and rotating assembly, a simulation oral cavity and chewing mechanical teeth. The left-and-right opening, closing and rotating assembly is arranged under the simulation oral cavity, and a first permanent magnet and a second permanent magnet which are arranged in the assembly are arranged to be opposite up and down; the upper chewing tooth (107) of the chewing mechanical teeth is aligned to a solution vessel (16) of the simulation oral cavity, that is to say, the solution vessel (16) serves as the lower chewing tooth (108). The full simulation chewing machine can simulate human body chewing actions such as up-and-down biting, left-and-right grinding, chewable gathering and turning by the cheeks and the tongue, the simulation degree is high, a food sample can be fully fragmented and dissolved, and therefore main ingredients in the food sample are fully dissolved out to be released. The device can be widely applied to research on release behaviors of the main ingredients in food samples.

Description

technical field [0001] The invention belongs to the field of bionic machinery, and in particular relates to a fully simulated chewing machine. Background technique [0002] With the promulgation of the "Framework Convention on Tobacco Control" (FCTC) ban on the spread of tobacco smoke in public places and people's wide acceptance of the dangers of smoking, as well as the country's high attention to harm reduction and coke reduction, the development of smokeless tobacco products Development has become one of the inevitable choices of the tobacco industry. A smokeless tobacco product is a tobacco product in which tobacco is consumed by the non-combustion route. It is mainly consumed by chewing, sniffing, inhaling, inhaling, inhaling, etc. It avoids the trouble of "second-hand smoke" of traditional cigarettes and has a good market prospect. [0003] As important product forms of smokeless tobacco, snus, liquefied tobacco and chewing tobacco in pouches have attracted more and ...
