The processes of rough rice milling for increase head rice yield are depending on several factors. The paddy rigidities are the one of these is effect to head rice yield. In the past research papers were showed that the qualities of milling were measuring from head rice yield and rigidities of rough rice were rerated to head rice yields. In this research aim to test the rigidities of the white rice with the bending test and showing the relation between white rice rigidities and head rice yield. The PTT1 RD41 RD31 and RD49 rice varieties were used in the experiment. The result showed that the high relation between the brown rice yield and head rice yield with determination coefficient was 0.81and the brown rice yield was heavy weight more than the head rice yield about 20%. The determination coefficient between the white rice rigidities and head rice yield was 0.16 showed that the less relation.

The main objective of the study is to design blades for chopping heart rice straw. This study is composed of three main testing parameters. The first parameter used is speeds at which the knife blades that will chop the straw. They will have 2 speeds one at 540 and the other at 720 rpm. The second parameter is the types of blades that will be used eclipse blades and smooth blades. The last parameter is the cutting edges. The eclipse and smooth types of the blades will have 4 5 and 6 cutting edges. For this test we use stubble sorted 50 heart rice straws. Placing the straw on the prepared steel and test with all three testing parameters repeating each testing parameter thrice and record the results. Based on the testing and evaluation the 6 edge eclipse blades with a speed of 720 rpm. Yielded the highes results for chopping heart rice straw at 66 percent. For the 6 edged smooth blades with a speed of 720 rpm the yield results for chopping heart rice straw was at 35.76%

This article presents the mini brown rice mill for household that is useful for farmers. After the harvest farmers keep their rice in the barn waiting for milling or paddy selling. In the rice market the cost of the paddy is very low but if the paddy is transformed to be the white rice or brown rice it could be more valuable. The mini brown rice mill is presented in this article. The rice mill was reshaped to be smaller and moveable. It consisted of four rubber crackers that turned around adversely in the different speed then the fan blew the chaff to be the brown rice and finally the brown rice will be scrubbed by the polishing machine to be the white rice. The result of this experiment revealed that the mini brown rice mill can produce more than 40 kilograms and around 10 kilograms per hour for the brown rice and the white rice respectively

The objective of this research was to study the dominant feature of Khao Wong glutinous rice Kalasin province for geographical indications. The effect of three cultivated areas of glutinous rice variety (RD6) consisting of Khao Wong Huai Mek and Kong Chai districts was investigated along with their physicochemical textural properties and thermal properties. For the effect of different cultivated areas on glutinous rice properties the significant effect of different cultivated areas on chemical compounds viscosity and textural properties was observed (p?0.05). There was no significant effect of cultivated areas on amylose content (p>0.05). The highest protein and ash contents and the lowest setback hardness and chewiness values were found in the sample cultivated in Khao Wong district area. The aroma compounds analysis of rice samples revealed that methanecarboxylic acid was observed in glutinous rice cultivated in all studied areas. Whereas the highest content of 122-Trimethylcyclopropylamine was found in the sample cultivated at Khao Wong and Kong Chai districts. In addition the highest content of 2-cis-9-octadecenyloxyethanol was observed in glutinous rice cultivated at Huai Mek district.

This research aims to study participatory learning process to strengthen rural communities through Leaung Rice 11 production which promotes self-reliability and capability of the communities. This is a participatory action research (PAR) with farm experimental methods. It demonstrates a model to empower community which allows members to identify problems discuss find commitment and approve incoming development. Researchers here are therefore facilitators helping people in the community to achieve effective production of Yellow Rice 11. After providing sufficient information about Leaung Rice 11 production the main problems identified is a high production cost with chemical fertilizer being abundantly used causing health and environment problems to the community. This results in a solution of choosing organic Yellow Rice 11 production that is harmless and friendly to the environment. Despite co-operative learning and problems identification locals also get an opportunity to plant Leaung Rice 11 with organic fertilizer and Effective Microorganisms (EM) as a model to safe cost. It is obvious that rice production is also increased (737.69 Kilogram per Rai). Moreover production cost decreases to 1227.50 Baht per Rai per family. This research provides the community ability to analyze self-problems and potentiality under modern research methodology; problems identification solution identification experiment process co-operative learning data collection data discrimination data analysis and data application.
