This type of dryer are able to dry paddy from 24% to 18% moisture content in short period with air temperature 100oC and high air velocity (8) without changing the riceвЂ™s quality. 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. Maybe i using wrong syntax or something? I have no idea how can i solve this error.Design and simulation of heat exchangers using Aspen HYSYS, and Aspen exchanger design and rating for paddy drying applicationДrying is a mass and heat transfer process which consisting of the removal of water by evaporation from solid.

I can modify one values but can't modify the others although they 'CanModify' attribute is 'True'. I have tried doing all the same using VBA and the picture was the same. But i can change that value handly in column specifications directly in Hysys, also It gives me error '70 Premission denied'. In this case everything work fine, but wen im try to change, for example, condenser pressure of column K-1 using syntax: This gave me the ability to modify the data of streams using syntax like: I am trying to write an interface between Python 3.7 and Hysys case.В I managed to establish a connection between them, connect Hysys as COM.Object.
