Description

Technical Field

[0001] The utility model relates to the technical field of grape crushing force measurement, in particular to a grape crushing force detection device based on airflow impact. Background Art

[0002] Grapes are an important economic crop used in the development of winemaking and juice products. During the brewing process, grapes need to be crushed for fermentation. The lack of research on the critical force of grape crushing makes it difficult to provide theoretical guidance for the design and development of grape crushing equipment and the determination of operating parameters. Current research on the critical crushing force of grapes often uses mechanical impact methods, where the grapes collide with a pressure sensor under mechanical force to measure the critical crushing force. However, mechanical impact can instantly damage the grapes and even cause them to break, affecting the accuracy of measurement results.

[0003] Therefore, based on the principle of non-destructive impact of airflow, a grape crushing force detection device based on airflow impact is proposed, which is of great significance for the accurate measurement of the critical crushing force of grapes. Summary of the Invention

[0030] The control system includes a laptop computer 14 , a power supply 15 , a relay 16 , a digital-to-analog converter 17 and a data acquisition card 18 .

[0031] The air compressor can provide a working pressure of 0 ~ 0.7 MPa. The filter 7, proportional valve 8, and solenoid valve 9 are installed on the mounting plate 3.

[0032] The pressure plate 11 is located directly in front of the grape storage platform 10, and a pressure sensor 12 is installed behind the pressure plate 11; the pressure sensor 12 is installed on a movable frame 13; the movable frame 13 is installed on the mounting plate 3 5, and can be horizontally moved to adjust the distance between the pressure plate 11 and the grape storage platform 10. The measurement accuracy of the pressure sensor 12 is not less than 0.005 N.

[0033] The data acquisition card 18 is mounted on the mounting plate 296 and connected to the laptop computer 14 via an RS232 serial port. The laptop computer 14 uses a digital-to-analog converter 17 to set the air pressure of the proportional valve 8 and the on / off state of the solenoid valve 9, as well as read the values ​​measured by the pressure sensor 12.

[0034] The second mounting plate 4 is provided with a power supply 15, a relay 16 and a digital-to-analog converter 17, wherein the power supply 15 is used to convert a 220V voltage into a 24V voltage for powering the system.

Repeating this process allows for multiple measurements, and the average value is then used to determine the critical bursting pressure of the grapes.
