This research’s objectives were to develop an energy saving rotary dryer for paddy using hot air recovery system and to evaluate the energy using. Rotary dryer divided rotating cylinder made of 304 stainless steel 2 mm of thickness 39 cm and 200 cm of diameter and length. The inverter was used to control speed of gear motor of 0.5 HP and rotating speeds of 1-3 rpm. The inside of cylinder composed screw and capture flights. The cyclone system was used to dust separating from the system. The moisture trap contained silica gel the outlet hot air was reduced moisture and recovered using. The fiber glass insulator was applied for reducing energy loss. The heating box composed 3 set of 1600 W heaters and blower motor power was 0.5 HP. In the experiment the drying temperature was varied of 50 60 70 and 80oC and cylinder speed was varied of 1 2 and 3rpm (15.66 10.66 and 5.66min of drying time). The initial moisture content of 10 kg paddy was 29.7?0.6 %wb. The result show that the optimum conditions drying temperature and cylinder speed were 70-80oC and 1 rpm (15.66 min) and final moisture content was 9.2-11.8 %wb. From the save energy testing found that the reducing of SEC was 0.4-0.6 MJ/kg water per drying cycle. There for this developed dryer can save energy using

This research was to apply graphical method as the input data combined with using database for developing reinforced concrete slab analysis and design. Visual Basic language was used for creating the GUI (graphic user interface) and coding and database file was used for storing data. The position of beam column and slab can define by drawing on GUI and this program will automatic translate to be the distances for using as data in process of analysis and slab design. Results from analysis and design were compared with manual calculation that they are a litter bit error because of rounding error. Moreover they can be more economically and more conveniently than results from VisStructure 4

Study to process of vegetable and fruit tablet which study about 2 types such as banana and kale. The first step; drying banana and kale by thermal processing with hot air oven at 605C for 30 min. Next grinded dried banana (DB) and dried kale(DK) to become powder size 80 mesh Aw 0.270.26 0.290.31 and 0.330.28. After that mixed %DB 25 %DK 37 %DC 37 %grinded sugar 32 %thickness agent 4 and %lubricant agent 2. The physical of V&FT has thickness 1.50.02 mm. diameter 10.03 cm. and weight 2.60.05 g. The resulted about sensory test was accepted by the panelists with the score above 7 (like moderately; 7.320.52) and was accepted all characteristic of V&FT. And V&FT was not found microorganisms that cause food to be rotten.

The objective of this study aims to develop a concrete boat by using lightweight concrete. The use of granular foam replaced the aggregate in various quantities to reduce the weight of boat. The replacement ratios of aggregate by the granular foam were 0 25 50 75 and 100% by volume of aggregate. The test results of compressive strength tensile strength modulus of rupture and unit weight of concrete were used to find out the appropriate mixture for producing the concrete boat. The results indicated that the appropriate mixture for producing concrete boat was the replacement of aggregate by granular foam at 100% which had the compressive strength at 28 days of 50.59 kg/cm2 and the unit weight was 949.71 kg/m3. The weight of lightweight concrete was lighter than the normal concrete about 57%. The prototype of lightweight concrete boat which had 1.04 m wide 2.20 m long and 0.38 m height had about 50 kg of weight. The maximum weight capacity of the boat was 240 kg. The cost of a lightweight concrete boat was about 650 baht

The objectives of this research are to study the operation model for highland development of the Royal Project the model of knowledge extension to the farmers the result of operation to the farmers by the Royal Project and studying of the effective factor of the Royal Project development. This research is use the quantitative by collecting the data by interviewing. The result of the research there are 7 important models of development by the Royal Project to the farmer on the highland; (1) the operation procedures (2) operation plan (3) Format of operations (4) Officers in the center and in the area (5) Values and corporate culture (6) The farmer in the area and (7) Potential of the area. For the knowledge extension to the farmers the advice/visiting to the farmers is in top level. The “support/facilitation to the farmers” there are a purchasing the goods and agricultural products and product quality development in very high level. And the result of operations the Royal Project to the farmers resulting in economy the higher income and increasing the asset in high level the liabilities decreased moderately. In the social the farmers are developing at the high level in every topic. It is shown that the resulting in operation of the Royal Project can help in social development. And in the environmental there is an increasing of a conservation of the upstream area in very high level. The factors that effect to the result of operation by the Royal Project in economy social and environmental are depended on the model of operation support/facilitation and the quality of the officers in the Royal Project.
