Eggshell Strength Tester

I. Product Overview

The Eggshell Strength Tester is a dedicated mechanical performance testing device developed for shelled poultry eggs such as chicken eggs, duck eggs, goose eggs and quail eggs. Through axial compression testing of the whole egg, the instrument records key data such as the maximum force before the eggshell breaks, the shell deformation and the egg height, providing quantitative evidence for poultry egg variety breeding, feeding management, grading and packaging, transport damage resistance research and product quality control.

III. Applications

This instrument is suitable for incoming inspection of fresh eggs, batch evaluation on farms, grading and packaging of poultry eggs, and storage and transport quality research. Through quantitative analysis of indicators such as the maximum force before eggshell breakage and shell deformation, it can assist in evaluating the eggshell load-bearing capacity, breakage resistance and quality differences between batches, providing data support for variety screening, feeding management, packaging optimization, transport condition evaluation and quality control. During specific testing, conditions such as sample placement direction, contact position, loading speed, trigger force, test temperature and sample quantity should be unified to ensure the accuracy, repeatability and comparability of test results across different batches, varieties and process conditions.

IV. Product Features

1. Dedicated accessories: *P/5S spherical probe — for puncture-compression testing of the poultry egg shell, measuring the eggshell breaking force and evaluating the anti-breakage strength of the eggshell; *Egg cup — used to fix the egg body; *Round plastic tray — to receive the broken eggshell; *Egg opener — for quickly opening chicken eggs, enabling efficient testing of poultry egg shells. *Probes can be customized according to sample characteristics and requirements.

2. Preset core parameters — the core parameters of shell breaking strength (breaking force), shell deformation (breaking distance) and shell thickness (item height) 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.
