What is the difference between a convection oven and a conventional oven?

Please verify the following points and require itemized written supplier responses:（commercial oven oven-convection） Convection ovens use fans to circulate hot air for more even batch baking, while conventional ovens rely mainly on top and bottom elements. Adjust temperature and time for convection mode rather than copying conventional recipes. Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
