Methodology
How Just Freeze Drying Evaluates Information
Every page on Just Freeze Drying draws on one or more of five information types, and every page says which one it is using. This page explains the framework and the source hierarchy behind technical content, so you can judge how much weight to give any claim.
The Five Information Types
General Guidance
Educational principles about freeze drying, food behavior, storage and rehydration drawn from accepted food preservation knowledge and practical experience. Clearly labeled as general guidance and never presented as test data.
Manufacturer Guidance
Information specific to a manufacturer or manual, identified as such. Exact settings, maintenance steps, error codes and vacuum targets are always treated as manufacturer-specific: check the manual for your machine.
Real-World Testing
Documented WeFreezeDryIt tests: batch results, weights, yields, rehydration behavior, observations and photos. None are published yet, and nothing is labeled tested until a real record exists.
Calculations
Values derived mathematically from measured or entered inputs, always labeled Calculated or Estimate. A calculated figure is never presented as a raw measurement.
External Laboratory Results
Results from an outside laboratory, used only when actually performed, clearly labeled External Lab Result and never implied to be internal work. None exist on this site yet.
Source Hierarchy for Technical Information
For technical content, information is weighted in a clear order. Higher-ranked sources override lower ones when they conflict, and the difference is always stated on the page.
- 1
Manufacturer Documentation
Model-specific operating procedures, safety guidance, electrical requirements, vacuum targets, maintenance schedules and error codes for a specific machine.
- 2
Verified WeFreezeDryIt Data
Batch results, weights, yields, rehydration observations, photos and process tests from documented real runs by the organization behind this site.
- 3
External Laboratory Results
Moisture, water activity, nutrition or microbiology results from an outside lab, where available, always identified as external.
- 4
General Educational Guidance
Broader principles about freeze drying and food that hold across machines and products, treated as guidance rather than evidence for a specific case. The weakest source is still useful, but it is always labeled as guidance.
The Freeze Drying Lab applies this same hierarchy to every record, and the Lab Methodology page shows exactly how measurements, calculations, observations and general guidance are kept separate.
Corrections & Ongoing Review
Information on this site is reviewed as part of an ongoing process, not a one-time event. When an error is identified, it is verified, corrected and documented as described on the Corrections page. A claim's label can change as evidence changes: general guidance stays guidance until a real, documented test exists to replace it.
The standards behind all of this, including which pages are reviewed most often, are on the Editorial & Accuracy Policy.
