AdvThermaLogic is thermal process engineering software developed by Advanced Food-Tech Solutions for continuous-flow and in-container thermal processing, covering process calculations, scheduled-process development, validation support and documented engineering output. AdvThermaLogic supports continuous-flow thermal processing for aseptic, HTST, UHT and hot-fill applications. It calculates process lethality and F-value, required hold-tube exit temperature, residence time and hold-tube design, flow regime and Reynolds number for Newtonian and non-Newtonian products, thermal and volumetric expansion, and process deviation. Results are reported so that delivered lethality is never overstated and required temperature is never understated, and residence time is computed on the fastest-moving element of product, the basis a scheduled process requires. Systems with direct steam injection or infusion and indirect heating are each handled on their own terms. AdvThermaLogic In-Container extends the platform to retort, canning and batch sterilization. It covers process design by Ball's formula, Stumbo's method, Hayakawa's method and the General method by numerical integration, heat penetration analysis for simple and broken heating curves with estimation of fh, fh1, fh2 and jc, temperature distribution study evaluation, retort process deviation evaluation, come-up-time correction, process optimization for lethality, quality and energy, and scheduled-process documentation prepared to 21 CFR Part 113. The suite is available in several editions. AdvThermaLogic Pro provides the full feature set, including 2D simulation, process deviation analysis, comparison tables, multi-segment hold tube, PDF export and audit-ready reporting, at 2,400 euro perpetual for a single seat, or 790 euro per year as an annual subscription. AdvThermaLogic Basic provides the core calculators for daily work, covering F-value, hold-tube sizing, residence time, exit temperature, process schedule and milk processing, at 790 euro perpetual. AdvThermaLogic Academic is licensed for teaching, coursework and research training at 1,000 euro for one administrator and four seats. A five-day free trial of selected Basic and Pro modules is available with no credit card. All prices exclude VAT. The software runs on Windows and macOS. AdvThermaLogic is written by a process authority and used by Advanced Food-Tech Solutions in its own consulting and validation work. It is intended for food engineers, process authorities, food scientists, technologists, quality assurance and food safety professionals, consultants, researchers and food-processing facilities that need scientifically based calculations, process development tools, validation support and documented engineering outputs. Alongside AdvThermaLogic, Advanced Food-Tech Solutions develops the Aseptic Tank SIP Validator, HX Studio for sanitary heat-exchanger engineering, AdvPiD CAD for hygienic process and P&ID development, process-schedule tools for aseptic and in-container processing, the AFTS F-Value Library of cited thermal-processing reference data, and a set of free web calculators. Advanced Food-Tech Solutions is based in Athens, Greece, available across the European Union for on-site work and worldwide for remote consulting.
