Description

The utility model is a measuring device and can be used to determine the quality of gluten in wheat grain and wheat flour by determining the amount of deformation of raw gluten under the influence of a load of a certain value for a given time interval, and is designed to assess the quality of grain products for use at breeding stations. in laboratories of research institutes, laboratories for variety testing, grain receiving points, as well as in the pasta, flour and bakery industries; can be used to determine the quality in the preparation of dough from wheat flour, wheat bread, bakery, pasta and flour confectionery products, to determine the characteristics of raw materials, planning the production process, predicting the quality of finished products.

A device for determining the resistance of a gluten sample to compression is known from the prior art (patent SU 1272240), which contains a housing, a support table for a test sample of gluten, a vertical stepped loading rod with a flat working surface of a larger diameter parallel to the support table, a rod guide, a brake mechanism, a reading device and element for centering and preliminary deformation of the gluten sample in the form of a shaped insert with a stepped internal cavity.

The disadvantages of the known device are that the arithmetic mean value of the IDC unit is calculated manually, which can lead to errors, and the quality of the analysis depends on the time spent by the laboratory assistant to carry out two measurements on the same device separately, which significantly affects the reliability of the result, since the time taken to test affects the chemical and physical properties of the gluten sample.

To reduce the measurement time and automate the calculation process, a device is needed that measures the deformation of gluten simultaneously for two samples. Automatic calculation of the average value is necessary to reduce the time of the operation, as well as to eliminate errors during manual recalculation.

The problem for the solution of which the utility model was created consists in the possibility of creating a device for the simultaneous measurement of several gluten samples on one device.

The technical result consists in increasing the accuracy while simultaneously measuring several samples of gluten and reducing the time for measuring the deformation of gluten.

The specified technical result is achieved with the help of the constructive implementation of the device.

The device consists of a control unit, base, two measuring modules. All elements of the device are located in its body and are interconnected by assembly operations at the manufacturer.

The control unit is equipped with a display for displaying information and a start button for the device. The functional purpose of the control unit is to generate a signal to control drives, measure the amount of gluten deformation, as well as to automatically calculate the arithmetic mean of the gluten deformation units (hereinafter - IDC). The control unit facilitates the simultaneous control of two measuring modules, as well as the automatic calculation of the received data from the measuring modules, which has a positive effect on increasing the measurement accuracy and reducing the time for measuring gluten deformation. The architecture of the control unit can be based on a personal computer, monoblock or other electronic computers known in the prior art.

The base is intended for placing gluten samples on its surface. The base can be made in the form of a flat plate. The base can be solid or divided into two separate parts. The base is connected to the control unit. The connection can be made, for example, by welding, gluing or riveting the bottom of the base to the top of the control unit. The presence of a base in the device makes it possible to simultaneously position several gluten samples for testing, which has a positive effect on increasing the measurement accuracy and reducing the time for measuring gluten deformation.

The measuring modules are designed to deform the gluten samples and transfer the test data to the control unit. Each measuring module is equipped with a mechanism for physically affecting gluten samples, consisting of a drive, a movable carriage, an optical sensor, an electromagnet and a component for a calibrated load (load component) necessary to determine or control the degree of load on the test samples. Data transmission from the measuring modules to the control unit can be carried out via a wired or wireless communication channel. The connection of the measuring modules to the housing of the device or to the control unit can be carried out, for example, by screwing. The drive can be designed as a stepper motor or as a mechanical motor. The presence of two measuring modules in the device, as well as the structural implementation of the mechanism of the modules, has a positive effect on increasing the measurement accuracy and reducing the time for measuring gluten deformation, since it allows simultaneous testing of two gluten samples independently of each other.

The device works as follows.

Two molded round-shaped gluten samples are placed on the base (1). After pressing the start button of the "START" device (7), the electromagnets (4) release the upper planes, which are load components (3), which in free fall, each individually, fall on the gluten samples, and under the influence of the load, the sample is deformed into for a given time interval. The display (6) counts down the set time. At the end of the countdown, the control unit performs calculations, displays the values of the IDK units for each sample and the arithmetic mean of the two indicators.
