| چکیده | ||
| با توسعه خشککنهای مدرن شلتوک علاوه بر سرعت بخشیدن به عملیات خشک کردن، می توان میزان ضایعات و به ویژه انرژی مصرفی را به حداقل ممکن کاهش داد. در این تحقیق اثر دمای هوا، دبی هوای ورودی و نوع رقم و همچنین اثر متقابلشان بر انرژی مصرفی و نرخ خشک شدن شلتوک در یک خشککن بستر سیال بررسی شد. دمای هوای ورودی در چهار سطح 45، 50، 55 و 60 درجه سلسیوس، دبی هوا در سه سـطح 12/0، 14/0 و 16/0 متر مکعب بر ثانیه و نوع رقم شلتوک؛ طارم محلی، فجر و شیرودی در نظر گرفته شده و آزمایشات به صورت فاکتوریل سه فاکتوره 3×3×4، در قالب طرح کاملاً تصادفی و در سه تکرار انجام شد. نتایج نشان دادند که در هر سه رقم مورد آزمایش، با افزایش دمای هوای ورودی علاوه بر اینکه انرژی مصرفی کاهش یافته، نرخ خشک شدن نیز بطور معنیداری افزایش یافته است. در دمای 45 و 50 درجه سلسیوس، افزایش دبی هوا تاثیر معنیداری بر نرخ خشک شدن شلتوک نداشته ولی در دمای 55 و 60 درجه سلسیوس با افزایش دبی نرخ خشک شدن نیز بطور معنیداری افزایش یافته است. همچنین نتایج نشان دادند که با افزایش دبی هوا ، انرژی مصرفی افزایش یافته است. | ||

| چکیده [English] | ||
| With the development of modern drying paddy in addition to speed up the drying process, and in particular the amount of waste can be reduced to the minimum possible energy consumption. In this study was investigate the effect of input air temperature, input air flow rate and variety also their interaction on energy consumption and drying rate in the fluidized bed dryer. The parameters of input air temperature at 4 levels of 45, 50, 55 and 60 °C, the air flow rate at 3 levels of 0/12, 0/14 and 0/16 m3/s and variety of paddy at 3 levels Tarom, Fajr and Shirudi was considered and tests was done in three replication in form of a 3×3×4 the 3-factor factorial design. The results indicated that In all three varieties tested, by increasing the intake air temperature as well as reduced energy consumption, drying rate also increased significantly. At 45 and 50 ° C, increasing air flow grain drying had no significant effect on the rate But at 55 and 60 ° C by increasing the flow rate of drying significantly increased. The results showed that by increasing air flow, increased energy consumption. | ||
