Mill Ltd., Chachoengsao Province, Thailand was studied. The results revealed that Khao
Hin Sorn Agricultural Cooperative Rice Mill Ltd. is royal patronage which is supported by
various agencies such as the Cooperative Promotion Department, and Land Development
Department. This cooperative collected paddy from 10 farmer members, with average
amount of paddy at 14 tons per year, and the paddy were delivered to the cooperative rice
mill for processing. The full mill capacity is 1.2 ton of paddy per day. The service charge
rate is one Thai baht per kilogram. The cooperative has produced rice in both packaging
and non-packaging for sale to consumers by themselves. Regarding the SWOT analysis
results, concerning the strengths, the cooperative rice mill was royal patronage that can
provide inexpensive milling service charge for farmers. Additionally, operation staff had
experience in rice milling for a long time. Whilst the weaknesses were the rice mill without
checked the quality of paddy before milling-process and did not have the specialized
technicians to repair a milling machine as well as budget deficit. In terms of the
opportunities, the rice mill had a wide range of support from organizations of budgeting,
staff, and administration. Moreover, farmers was preferred consuming rice grown by their
own. Finally, the threats were the rice mill which located in a non-rice-farming area, and it
operated less than the full milling capacity. The collaboration with supply chain partners
should be encouraged to increase the quantity of paddy for the milling process.
