چکیده

مواد غذایی از ترکیبات مختلفی تشکیل‌شده‌اند و بعد از مدتی عمر مفید خود را از دست می‌دهند و یکی از روش‌های افزایش ماندگاری مواد غذایی فرآیند حرارتی می‌باشد، ازاین‌رو در این تحقیق یک دستگاه گرمایش اهمیک ساخته شد تا فرآیند حرارت‌دهی انجام شود. در این فرآیند سه گرادیان ولتاژ ورودی (V cm-1 33/8، 83/10 و 33/13) و سه درصد کاهش وزن نمونه (10، 20 و 30 درصد) نسبت به وزن کل انتخاب گردید. طی فرآیند حرارتی روند بازده انرژی، بازده اکسرژی، اکسرژی تلف‌شده و پتانسیل بهبود بررسی شد. تمامی آزمایش‌ها در سه تکرار انجام گرفت و نتایج با استفاده از نرم‌افزار SAS برای بررسی آماری در آزمایش فاکتوریل در قالب طرح کاملاً تصادفی تجزیه ‌و تحلیل شد. با توجه به نتایج به‌دست‌آمده بیشترین مقدار بازده انرژی و اکسرژی در گرادیان ولتاژV cm-1 33/13و برای پتانسیل بهبود و اکسرژی تلف‌شده در گرادیان ولتاژ 33/8 می‌باشد. بیشترین بازده انرژی 16/91% در درصد کاهش وزن 10% و برای بازده اکسرژی 51/59% در درصد کاهش وزن 30% بوده است و بیشترین مقدار اکسرژی تلف‌شده و پتانسیل بهبود در درصد کاهش وزن 30% و به‌ترتیب kW 76/6 و 624/5 بوده است.
