I have a small (under 1 L) plastic storage container that needs an instant-cooling insert. The goal is to chill freshly cooked or ambient food down to refrigeration range within minutes, using a single-activation endothermic reaction that is 100 % food-safe and sealed. What I am looking for • A complete engineering concept for the insert or internal compartment that fits the container’s footprint without reducing usable volume more than necessary. • Choice of endothermic chemistry that is GRAS-compliant, non-toxic even if the outer capsule were breached, and capable of at least a 20 °C temperature drop. • Encapsulation strategy (film, pouch, rigid pod, etc.) compatible with polypropylene and other common food-grade plastics, including wall thickness, sealing method, and thermal conductivity data. • 3D CAD files (STEP or SolidWorks) ready for rapid prototyping. • Bill of materials with supplier references for chemicals, barrier films, and any specialty additives. • Brief test protocol outlining how I can verify cooling performance, leach-test results, and reusability limits (if applicable). Acceptance criteria – Insert snaps securely into the lid or base of the container with no tools. – No component may raise food temperature once reaction is finished; latent heat must dissipate safely. – All materials meet FDA food-contact guidelines and EU 10/2011. – Supporting calculations show total enthalpy change and predicted cooling curve for 250 g of food mass at 60 °C. If you have experience in food-grade packaging, thermal engineering, or instant cold packs, your insight will be invaluable. I am ready to move quickly once we have a solid, verifiable design.

Hello, I am a mechanical/product design engineer with experience in food-grade plastics and thermal systems. I can develop a complete engineering concept for your instant-cooling insert that is compact, safe, and ready for prototyping. My approach includes: • Selection of a GRAS-compliant, non-toxic endothermic system capable of ≥20°C temperature drop, with safety review in case of capsule breach. • Design of a single-activation insert using a sealed dual-chamber pouch (burstable inner membrane) integrated into a snap-fit cartridge for lid or base mounting. • Encapsulation strategy compatible with polypropylene, including multi-layer barrier film specification, sealing method, wall thickness guidance, and thermal conductivity considerations. • Full 3D CAD delivery (STEP/SolidWorks) optimized for injection molding and rapid prototyping. • Detailed Bill of Materials with supplier references for chemicals and packaging materials. • Brief validation protocol covering cooling performance, temperature curve measurement, post-reaction safety, and basic leach-test outline. I focus on practical, manufacturable solutions — not just concepts. Delivery within 7 days including CAD, BOM, and test plan. I look forward to collaborating on this innovative product.
