Sample assessment
The bromelain powder has two jar arrangements without a fixed size target. Enzyme activity is a separate selection criterion that this size record does not measure. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Record milling outcomes; no numerical size target is supplied.
Equipment and selection
The recorded planetary machine is XQM. The corresponding TENCAN family is the Vertical Planetary Ball Mill. The jar volume identifies the test container and does not establish an exact machine variant or production capacity. Equipment association follows the recorded machine designation.
Test setup
| Recorded planetary machine | XQM |
|---|---|
| Documented setup | Initial 250 mL zirconia jar and standard zirconia balls; 66 g powder; air-assisted dry milling; speed setting 450. |
| Recorded operating cycle | Run 5 / pause 1; units not stated in mode field |
Speed values are reproduced as recorded settings. A rotational unit and planetary-disc versus jar-speed basis are not stated, so these numbers are not labelled rpm.
Recorded procedure and results
The zirconia arrangement measured D50 = 22.13 µm and D90 = 46.77 µm after 3 hours. A subsequent agate-jar and agate-ball arrangement measured D50 = 26.97 µm and D90 = 53.35 µm after 1.5 hours. The source does not establish that these were matched aliquots with identical feed histories.
Interpretation
These are measured distributions for two recorded arrangements, not a controlled proof that one jar material is superior. The values are retained with their individual times. Enzyme activity and temperature were not measured, and the record imposes no particle-size threshold.
Practical precautions
Evaluate enzyme activity through an appropriate independent assay. Record sample temperature and the feed split for a controlled jar comparison, and confirm whether the second arrangement used fresh feed or previously treated material.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Omnidirectional Planetary Ball Mill. For bromelain powder, a matched QXQM trial can test whether changing orientation affects the bromelain distribution while assaying enzyme activity separately. Keep sample mass, media and sampling times controlled. This is a proposed comparison; the test record does not demonstrate a superior result for that alternative. Confirm jar compatibility and the permitted complete loaded mass before selecting a configuration.
Procedure records XQM; related product is the corresponding tested machine family. Exact variant is not inferred from jar size. Air-assisted operation is explicitly recorded, so the TENCAN Air-Cooled Planetary Ball Mill catalog page is also associated.
