This may affect the head rice yield and rice quality.ДЇluidized bed dryer operating in such ways where hot air passes through the bed and then through the suspended grains which is perpendicular to the direction of flow. However, this dryer has been associated with high energy consumption and produces uneven dried product due to an inconsistent air flow distribution. In addition, the operation of the machine is easy. The advantages of this dryer are inexpensive compared to the other dryer and have a faster withdrawal of dried paddy. Currently, IBD is used by Padiberas National Berhad (BERNAS) as a second dryer after fluidized bed dryer (FBD) with the ability to dry grain with high moisture content of 20-26% w.b. Paddy that is about to be dried was placed a foot deep and hot air are forced to go through the bulk of paddy from below the bed. This type of dryer consists of perforated sheet floor (bed) with a plenum chamber below it that forced air directly or by the assistance of a duct system (6). Inclined bed is a common example of fixed bed dryer which possess basic design of paddy drying technology. There are many industrial paddy dryers such as inclined bed dryers (IBD), fluidized bed dryers (FBD), re-circulating bed dryers, and continuous-flow dryers. The moisture content of paddy typically needs to be reduced to 12-14 wt% (5) before it can be dehusked (3).

With the increasing demands, natural drying is no longer favourable as it requires longer time and massive space for drying. Drying process for paddy however, has to be carried out right after the paddy is harvested. In Malaysia itself, 600000 ha of the total area was covered solely for rice cultivation and a bulk of 2 million tonnes of paddy was produced annually from 400 rice mills of various capacity (4). (2), study shows that 586, 787 thousand tonnes of rice are annually consumed. Rice is a staple crops used by half of the earth population as a basic needs (2) including diets, source of income, and is one of a major economic contributors (3), especially in Asia.

Different drying methods are used to dry different agricultural products (1). The main purpose of drying is to reduce the moisture content in order to prevent the growth of microorganisms. It is an important process for mankind due to the great effect on the quality of the products. Drying of agricultural products is one of the preservation methods that used from long time ago.

It is one of the best tools present and will definitively recommend this software as well. He created DWSIM since 2008 and has been updating it ever since. He is a Brazilian process engineer which has been working mostly for Petrobras. DWSIM comes from DW = Daniel Wagner, SIM = Simulator.
