This research aims to collect and analyze financial data as well as assess financial feasibility and analyze business environment for investment in rice seed production of rice community center in Muang district Phitsanulok. Primary data in financial information used in the study were collected from rice seed center and rice community center. Secondary data were collected from documents and information of both government and private agencies. The research found that rice community center in Muang district Phitsanulok gained rice seed support from the Rice Department for seed production. However there were problems in production management that were not in accordance with rice seed production standard. Therefore the center had to change it operation from manufacturer to be buyers of rice seeds for its members. Financial analysis revealed that in terms of rice seed production cost the total cost per rai was 3800 to 7500 baht depending on the method of rice growing. Income from sale could be classified as sale price per sack (25 kg) at 575 baht per sack and sales price per ton from 11000 to 15000 baht. Analysis of business environment of the community center showed that the existing condition did not support business performance. Thus the possibility of investing in rice seed production was low.

The objectives of this study were to develop the paddy washing machine for community rice milling machines to extend this technology to rural community and introduce to commercial production. The experiments were conducted at the Department of Agricultural Engineering and Technology Faculty of Agriculture and Natural Resource Rajamangala University of Technology Tawan-ok Bangpra Campus Sriracha Chonburi. The results showed that paddy washing machine was suitable for high moisture content paddy between 20-25 % and washing for 1-3 minutes demonstrated better milling quality than unwashed paddy. Performance test of this developed paddy washing machine using drum speed at 35 rpm drum slopes of 1 2 and 3 degree and 21.60 % MC KDML 105 paddy could reach capacity about 150-200 kg/hr. The milling quality was significantly different at 95% confidence level from unwashed paddy. Furthermore this machine provided 1% better in purity and 11% better head rice yield at the same milling degree. From the study it can be concluded that increasing drum slope gave higher capacity higher power efficiency and lower water usage. The best condition was working with drum slope of 3 degree. The paddy washing process gave higher purity of paddy head yield and power efficiency of washing process while the color property was not significantly different from unwashed paddy at the same milling degree.

The purpose of this research is to estimate the affects of water content (27 37 and 47 % wet basis) cooking time (1 3 and 5 hr) at 110oC and germinating time (24 36 and 48 hr) on chemical composition structure and properties of germinated purple rice flour. A Box-Behnken design under the response surface methodology was performed to optimize their composition. Rajamangala University of Technology Lanna Nan was research place. Results demonstrated that germinating time had no significantly effect on protein and lipid content but resulted in increasing crude fiber and decreasing carbohydrate and amylose content with increase in germinating time. Scanning electron micrographs (SEM) revealed the presence of polyhedral shape and agglomerations. Birefringence was evidenced. Pasting properties of germinated purple rice flour showed an increase in the pasting temperature but a decrease the peak viscosity breakdown final viscosity and setback (p<0.05) as germinating time increased. Modified rice flour were increase in carbohydrate and amylose content and decrease in protein lipid ash and fiber as water content and cooking time at 110oC increased. Change in birefringence of starch granule after heating at 110oC was examined by a polarized light microscope. SEM showed the presence of creak surfaces and agglomerations. The swelling power of germinated purple rice flour decreased with increase in cooking time. The solubility at 85oC of germinated purple rice flour was increased in each level of water content.

This study was undertaken to determine effect of bio-extract fermented from pig placenta and effect of wood vinegar solutions on seed germination percentage and speed of germination of 2 rice cultivars Chai Nat 1 and Sang Yod Phattalung. The experiment was conducted in factorial in completely randomized design with 2 factors and 4 replications. The first factor was ratios of the solutions to water and the second was duration for seed incubation. The results demonstrated that wood vinegar showed more positive effect on rice seed germination performances than that of bio-extract. Speed of germination was affected by an inter-action between the dilutions of the solutions and the duration for seed incubation. In Chai nat 1 experiment the seed soaked in 20 times dilution of bio-extract and subsequently incubated for 24 hrs increased speed of germination of the seed. While soaking the seed in 400 times dilution of wood vinegar and incubated for 24 hrs could enhance both percentage and speed of the seed germination. In Sang Yod Phattalung experiment soaking the seed in 50 times dilution of bio-extract and subsequently incubated for 48 hrs or soaking the seed in 300 times dilution of wood vinegar and incubated for 48 hrs could enhance both percentage and speed of seed germination. According to the results we concluded that soaking rice seed in bio-extract of pig placenta fermentation or in wood vinegar solutions could enhance the seed quality.

The objectives of this research were to develop the quick cooking rice combination with nutrition values check. The shelf life of quick cooking rice in difference packages was also studied. The experiment was set at Agricultural Engineering and Technology Division Faculty of Agriculture and Natural Resources Rajamanagala University of Technology Tawan-ok Chonburi. The study revealed that Pathumtanee 1 rice variety both milled rice and brown rice could be produced quick cooking rice. It could be cooked in boiled water only 7 and 10 minutes respectively by using alcohol fuel which easily comfortable and suitable for the camping tourism. The nutrition values of the quick cooking rice weren’t significantly difference from the ordinary rice. The shelf lives of quick cooking rice in plastic bags were not less than 6 months. During storage the moisture content water activity and free fatty acid value of them weren’t significantly difference (p>0.05). This quick cooking rice trends to cook easily and could be the new innovation for the camping tourism.
