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 aimed to investigate for pineapple leaf paper drying. In this study process of drying the paper as a final step after the other. Paper drying time takes in solar energy to dry naturally for at least 2-3 days or more without natural sunshine. Solar hybrid energy dryer was designed for drying faster than traditional drying. The development of solar hybrid energy dryer ability to operate continuously. The solar dryer receives the heat from sunshine by passing into the solar panel dimension 1 x 2.6 m2 . The panel was installed on the top of the oven which declined 15 degree from the ground. The dimension of the oven is 1 x 1.05 x 1.30 m3 and have added heat to paraphrase another 2 rooms and heater 4 kW with controller and have added heat to paraphrase another 2 rooms. The dryer installed heater 4 kW with temperature controller and blower 0.22 kW serves as the circulation of heat in the oven to constant flow of 0.138 m3 / s. Experiment research test 3 types ; the use of solar energy alone the use of solar heater with a temperature of 50 55 and 60 °C and the heater only at 50 55 and 60 °C with three temperature settings. The variables in the study such as temperature humidity in the dryer humidity and Solar energy affect the pineapple leaf paper drying time. Experimental results from solar heater hybrid with 60 °C temperature setting was dried in minimum period of 3 hours and half at an average initial moisture content 1043.70% db to the final moisture content of 9.12% db. Highest average temperature in the dryer was 64.33 °C with electrical energy consumption 10.5 kWh. The use of only solar drying was dried in maximum period of 5 hours at an average initial moisture content 1070.98% db to the final moisture content of 15.84% db. Highest average temperature in the dryer was 39.89 °C with minimum electrical energy consumption 10.5 kWh.

The objective of this research was studied the quality and consumer acceptance of corn milk with sugar coating process and pasturization by selected from three corn milk formula. The first formula was the most appropriate. Then pasteurized corn milk with 3 levels of total soluble solid; 9 10 and 11 Brix respectively. The suitable total soluble solid for pasteurized corn milk was 11 Brix. Physicochemical properties. The color values L * a * b * pH equals 74.95 21.03 34.41 and 07.16 respectively. Protein fat fiber moisture ash citric acid lactic acid and carbohydrates. Percent 2.28 1.48 2.22 68.48 0.26 0.14 0.24 and 25.18 respectively. An average sensory score of an appearance viscosity taste and overall liking from 30 panelists had significant (p 0.05) higher than other treatments. The optimum corn milk powder by coating sugar with the ratio of corn milk : sugar was 50 % (by volume/weight) of sugar was dried in tray dryer at 70 C. The color values L * a * b * were 39.89 -2.10 and 10.38 respectively. The sensory acceptance of corn milk from the market was significant (p 0.05) higher score than reconstituted corn milk powder.

The objective of study was to design and development of spray drying technology for production of salt powder. The process design and build spray dryer that consisted of three parts: an atomizer a drying column and a dry powder collecting unit. The operation of a spray dryer was co-current flow. A drying column had diameter 0.5 m high 1.5 m and heater 15 kW with automatic temperature control PID 220 V AC power. The test used a saline solution. The inlet air temperature had 5 levels: 130 140 150 160 and 170 ?C. The inlet air velocity had 5 levels: 8 8.5 9 9.5 and 10 m/s. The results were a spray dryer be able to saline solution became salt powder with moisture content between 1.0 - 2.5 % (wet basis) which was in the standard of pure consumable salt (TIS 2086-2544) and can be classified at first class that moisture content had no more than 3 %

Devlopment of Screen Printign Devices Prototypes for Textile lndustry was a research project which it was established to solve the practical learning of the faculty of industrial textile and fashhion desing students at Rajamangala University of Technology Phra Nakhon. This set had 3 important machines such as a self assembly aluminum block screen an automatic aluminum screen could saved the saved the screen fabric1.76 m2 reduced the chemical usageand waste minimization in the process.The practical time reduced from 16 minutes to 1 minute using the automatic aluminum screen coating. The efficiency time was 97.81. The 400 gram emulsion consumed obtained the thin film layer on the screen fabricand evenness.The sharpen pattern displayed when the exposed time was 3minutes.Moreoverthe drying and fixation machine was completely for natural fiber and synthetic fibers at 80-180 C. Therefore the Screen Printing Devices Prototypes was effectively used in textile industrialdispose of the practical learning problemraw material savingand waste minimization adjacent to clean technology process.The prototype set was produced by house equipmentsand extended for textile industrial.
