Soybean Film Strength Tester

I. Product Overview

The Soybean Sheet Strength Tester is a dedicated texture analyzer developed for non-fermented soybean products such as soybean sheets, dried tofu and thousand-layer tofu. Through test methods such as tensile and puncture testing, the instrument quantitatively evaluates key indicators including breaking distance, breaking force, tensile force, rupture force, puncture force, elongation and toughness, providing data support for raw material screening, formula optimization, production process control and finished product quality evaluation.

III. Applications

This instrument is suitable for texture characterization evaluation, quality control and process comparison of fresh soybean sheets, dried tofu, thousand-layer tofu and their rehydrated products, covering application stages such as raw material screening, formula optimization, production process adjustment, product quality evaluation and batch consistency control. Through quantitative analysis of indicators such as breaking distance, breaking force, tensile force, rupture force, puncture force, elongation and toughness of soybean products, it can assist in evaluating the structural strength, extensibility, rupture resistance and texture differences of the products, providing a data basis for production process control and finished product quality evaluation. During specific testing, conditions such as specimen size, moisture state, sampling position, loading direction, test speed and end-point determination should be unified to ensure the accuracy, repeatability and comparability of test results across different batches and process conditions.

IV. Product Features

1. Dedicated accessories: *P/0.5 gel probe — for soybean sheet tensile testing, measuring rupture force and elongation to characterize the toughness and extensibility of soybean sheets; *P/TPB dough sheet puncture probe — for soybean sheet puncture testing, measuring the puncture force and evaluating the rupture resistance and texture uniformity of soybean sheets. *Probes can be customized according to sample characteristics and requirements.

2. Preset core parameters — the core parameters of breaking force and breaking distance are preset, so results can be read directly after testing, eliminating complex curve interpretation.

3. Human-machine interaction: 7-inch HD touch screen, supporting Chinese-English bilingual switching, intuitive and simple to operate.

3. Real-time curve display: automatically draws and displays data curves and supports switching among 4 types of coordinate axes (time-load, time-deformation, deformation-load, strain-stress) to analyze data relationships from different angles.

4. High-precision measurement: equipped with an industrial-grade high-precision analog-to-digital conversion chip and a customized force sensor, delivering excellent acquisition precision and small errors.

5. Test modes: multiple test modes are built in and can be selected; users can add the test modes they need according to their own testing requirements, adapting to different sample characteristics and testing needs.

6. Motion architecture: closed-loop motor drive + double-row linear rail slide table, ensuring a displacement accuracy of up to 0.001 mm, while limit protection and overload protection guarantee the safety of both user and instrument.

7. ★ Test playback: the system software records the whole test process. Tests at any time can be traced, with data restoration, curve redrawing and synchronous data playback, so as to view and analyze the test details of the queried sample.

8. Automatic data storage: test data is automatically stored and will not be lost after power failure; up to 5,000 A4-format data reports can be stored, each with a curve chart, and data can be exported via a USB interface — suitable for both quick report generation on the production floor and data archiving in the laboratory.

9. ★ Load calibration function: one-key calibration without multi-point calibration, ensuring the measurement accuracy of long-term use.

10. ★ GMP management system: a GMP management system is standard, supporting hierarchical user permissions and full-chain traceability of operating procedures.

11. Wi-Fi connection function; the device supports remote OTA upgrade and maintenance.

12. ★ Physical keys: the texture analyzer main unit is provided with physical keys, through which the probe height can be adjusted up and down.

13. ★ Multiple standard probes: the standard probes are subject to the packing list; a variety of probes of different specifications are optional, and customization and quick replacement according to sample and test method are supported.

14. ★ Height calibration: height calibration limits the extreme stroke of the probe. It avoids incorrect parameter settings that would cause the probe to over-press and directly hit the sample table.

15. ★ Instrument protection: emergency stop, upper and lower limit protection, and overload protection of the force sensing unit.

16. ★ Probe name, length and cross-sectional area can be entered; a probe already associated with historical tests cannot be deleted directly, avoiding the invalidation of historical data due to missing probe information.

17. ★ Sensor replacement: sensors of different ranges can be switched quickly without dismantling the whole machine or using complex calibration fixtures.
