Abstract

The utility model relates to a solid food mechanical texture property tester, which comprises a special fixture, a transmission mechanism, a sensor, a PLC as well as an input device and an output device that are connected with the PLC, wherein the special fixture is a mouth cavity of a simulation body and comprises an upper half part and a lower half part, cheek teeth which are corresponding on position are assembled on the upper half part and the lower half part, the sensor is arranged on the lower half part of the fixture, and the upper half part of the fixture is connected with the transmission mechanism; the transmission mechanism is a stepping motor controlled by the PLC, and the PLC can control and calculate the displacement quantity of the upper half part of the fixture; and the sensor can measure the pressure value obtained at the lower half part of the fixture and transmit the pressure value into the PLC for treatment. The solid food mechanical texture property tester can scientifically detect the stress size of solid foods while being chewed as well as the pressure value and the deflection quantity when solid foods in the simulated mouth cavity are compressed by the cheek teeth to break off and also can display and print relevant data after being digitized.

Description

Solid body food mechanical texture characteristic tester

Technical field

The utility model relates to the food inspection technical field, particularly a kind of solid body food mechanical texture characteristic tester.

Background technology

The sense organ discrimination method is the method for main employing during food quality detects, and its essence is exactly to rely on vision, sense of smell, the sense of taste, sense of touch and the sense of hearing to wait mode of appearance, color and luster, smell, flavour and rigid, the cohesiveness of identifying food.No matter which kind of food is carried out sensory quality assessment,, and often be before physics and chemistry and Micro biological Tests method, to carry out always said method is indispensable.

As mentioned above, the mechanical texture characteristic of existing solid food, as: rigid, cohesiveness all is to be judged by the organoleptic analysis by the expert, does not have quantitative detection means to judge the quality of comparative product quality.But this but have following defective by the sensorial subjective determination methods that detects of the mankind:

1, owing to need carry out manual detection by the expert, therefore, detection efficiency is low.

2, lack the science judgment foundation, particularly can not carry out the detection and the judgement of datumization to rigid and feature cohesiveness, therefore, repeatability is also relatively poor.

The utility model content

The purpose of this utility model provides a kind of solid body food mechanical texture characteristic tester, mainly solving existing detection need manually carry out by the expert, detection efficiency is low and lack the technical matters of scientific basis, it can scientifically detect the size of solid food suffered strength when being chewed and food in the oral cavity of simulation molar compressing solid food when rupturing the pressure size and the deflection of solid food, and can will show after the relevant data digitizing and print.

For solving the problems of the technologies described above, the utility model is achieved in that

A kind of solid body food mechanical texture characteristic tester is characterized in that: it is made of unit clamp, gear train, sensor, PLC (Programmable Logic Controller) and the input that is connected with PLC, output unit; Wherein:

This unit clamp is the oral cavity of analogue body, and anchor clamps are made of the first half moving up and down and Lower Half, and is equiped with the corresponding molar in position on the first half and the Lower Half, and the Lower Half of anchor clamps is equipped with sensor, and the first half of anchor clamps links to each other with gear train;

This gear train is that the signal output part of this sensor is connected to the signal input part of PLC by the stepper motor of PLC control;

This input media is connected PLC respectively with output unit.

Described solid body food mechanical texture characteristic tester is characterized in that: this input media and output unit comprise touch-screen.

Described solid body food mechanical texture characteristic tester is characterized in that: this output unit comprises printer.

Described solid body food mechanical texture characteristic tester is characterized in that: this sensor is connected to PLC by A/D converter.

By technique scheme, the technique effect that the utlity model has is:

Instrument of the present utility model can demonstrate exactly, and solid food is subjected to the size of strength in chewing, the size of size that food is under pressure when beginning to rupture and food deflection, thus can make quantitative evaluation to rigid, the cohesiveness of solid food.Testing process is simple to operate, efficient is high, the detection information science of acquisition and accurate.

Embodiment

See also Fig. 1, it is the structural representation of a kind of solid body food mechanical texture characteristic tester of the utility model.As shown in the figure: it is made of unit clamp 1, gear train 2, sensor 3, PLC4 and the input and output device that is connected with PLC 4, and this input media, output unit comprise touch-screen 5, and this output unit also comprises printer 6.Wherein:

This unit clamp 1 is the oral cavity of analogue body, anchor clamps are made of the first half and Lower Half, and be equiped with the corresponding molar in position on the first half and the Lower Half, the process that the first half and second parts can upper and lower mobile simulation be chewed, the Lower Half of anchor clamps is equipped with sensor 3, and the first half of anchor clamps links to each other with gear train 2;

This gear train 2 is the stepper motors by PLC 4 controls, the displacement of the PLC may command and the calculating anchor clamps first half; This sensor 3 can record the force value of anchor clamps Lower Half acquisition and be transported among the PLC 4 and handle, and the force value signal that this sensor 3 records is transferred to PLC 4 after handling by A/D converter 7.

This input media can be to PLC 4 input test parameter information, and the detection information that this output unit can obtain PLC 4, the parameter information of analyzing data message and input are exported.

The operating process of this instrument is:

Earlier, use 1N to the zero setting of instrument power valve system, 2N, 5N, 10N, 20N, 30N, the standard test weight of 50N is single one by one to be placed on the sensor of anchor clamps Lower Half, and the error that makes demarcation displayed value and standard test weight value is less than 1%; After the power valve system is demarcated and to be finished, tested solid food is lain in the middle of the anchor clamps peeling weight;

Start gear train, the screen display solid food is stressed to be zero, molar on the anchor clamps first half contacts with solid food surface one, output unit is shown as the stress value on the solid food, anchor clamps continue to move down, when tested solid food moment institute before fracture stressed when maximum, PLC write down automatically maximum power value and this moment the anchor clamps first half effective displacement, i.e. deflection during solid food fracture; Stressedly on the solid food immediately reduce rapidly, fracture promptly taken place, printable when going out this tested solid food and chewing required strength (rigid) and the deflection (cohesiveness) during fracture

Test is finished.

Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the application's claim change and modification, all should be technology category of the present utility model.
