AdvThermaLogic In-Container is desktop thermal process engineering software developed by Advanced Food-Tech Solutions for retort, canning and batch sterilization of food in hermetically sealed containers, covering thermal process studies, scheduled-process development, validation support and documented engineering output. Its nine core modules carry a retort process from the first probe in the vessel to the filed schedule and the lot review. Temperature Distribution evaluates retort medium uniformity from multi-probe, multi-run data, with sustained probe arrival, plateau spread and stability, and the cold zone, judged against the IFTPS criteria. Heat Distribution fits fh per probe and per run and reports within-run and across-run variation to locate the slowest-heating position. Heat Penetration estimates fh, jh, fc and jc from the fitted heating and cooling curves and the F0 the record delivers. Broken Curve handles products that change heating rate mid-process, with fh before the break and f2 after it. Process Design calculates process time for a target F, or the F a given time delivers, by Ball's formula, Stumbo's method and Hayakawa's method side by side, checked against the General Method by numerical integration. Process Control reviews recorded lots with General-Method F0, cook value and formula cross-checks. Process Deviation evaluates recorded extremes against the filed schedule and produces a disposition record. Process Optimization holds the target F while maximizing retention of a quality attribute. Process Schedule prepares the process conditions, critical factors and documentation a scheduled process is filed with under 21 CFR Parts 113 and 114. Helpers add F-value by the General Method, initial-temperature correction, cold spot studies, a convection model for liquid products in still containers, tunnel pasteurizer lethality, pH classification and routine retort audits. A shared catalog of retort types, heating media and container types, study protocols, guidance pages and regulatory references for the US FDA, USDA FSIS, EU, UK and Codex are built in. Results are reported so that delivered lethality is never overstated. The AFTS F-Value Library is built into every module: more than 4,300 records of F targets, commercial processes, scheduled processes and D and z values, kept exactly as published. AdvThermaLogic In-Container launches on 16 December 2026 in two editions. In-Container, for process authorities and small businesses, is 2,900 euro as a one-time purchase. In-Container Business, for large businesses and corporates, is 3,500 euro and adds Live Process Control (SCADA) with real-time F0 on the running batch and a tamper-evident batch record with 21 CFR Part 11 technical controls, Retort Equipment Maintenance, and Vent and Come-up Check. One retort connection, commissioned by AFTS, is included; each additional retort is 2,000 euro. Both editions include the first year of the F-Value Library, maintenance and updates, then an optional annual subscription of 500 euro. All prices exclude VAT. The software runs on Windows. AdvThermaLogic In-Container is written by a process authority and used by Advanced Food-Tech Solutions in its own consulting and validation work. It is intended for process authorities, thermal process consultants, food engineers, quality assurance and food safety professionals, researchers and food-processing facilities operating retorts. Advanced Food-Tech Solutions is based in Athens, Greece, available across the European Union for on-site work and worldwide for remote consulting.
