چکیده

یکی از جنبه‌های مهم فناوری خشک‌کردن به‌خصوص در فرآیندهای صنعتی، مدل‌سازی و شبیه‌سازی فرآیند خشک‌کردن می‌باشد. در این پژوهش با استفاده از روش عددی شبه‌طیفی معادلات انتقال جرم مربوط به فرآیند خشک کردن سیب حل گردید. جهت بررسی صحت و دقت مدل ارائه شده نتایج حاصل از حل عددی مدل با نتایج آزمایشگاهی مورد مقایسه و ارزیابی قرار گرفت. جهت تأیید بیشتر دقت روش شبه‌طیفی، مثال عددی دارای جواب دقیق حل گردیده و مقدار خطا محاسبه شد. نتایج حاصل از مقایسه داده‌های مدل با نتایج گزارش شده توسط سایر محققین دارای ضریب همبستگی بالاتر از 997/ و ریشه میانگین مربعات خطا کمتر از 1561/0 می‌باشد که بیانگر دقت بالای روش عددی شبه‌طیفی ارائه شده برای حل معادله انتقال جرم خشک شدن سیب می‌باشد.
