Warehouses and production process plants are located both in Prapadaeng district of Samutprakarn province and upcountry in Bangsai district, Ayudhaya province, having a combined warehousing storage capacity of 300,000 tons. This also includes 47 silo bins, each holding 600 tons of rice, and the other 28 bins of 200 tons each atthe main factory in Samutprakarn province.

Capital Rice is a pioneer in the use of the silo storage system to provide a consistent supply of premium quality rice. The principal warehouse covers spacious areas for container loading under roof protection, and a wharf which can accommodate ocean- going vessels for direct speedy loading.



To ensure prerequisite qualities or subsequent grading and storage rice processing begins with grains be weighed and checked for color, moisture content and length before further process.

All rice will have to pass through a series of cleansing procedures, applying modern technology and using the most modern machinery and equipment. At each stage of the process, any metal particles will be removed from the grains by a highly-efficient magnet device. Foreign particles such as small pebbles and shell are further effectively removed through a D-stoning machine. And thereafter, the grains are polished as part of the cleansing process, and being carried through a rotary sifter via a modern conveyance system to eliminate dirt particles. The grains are then graded and sorted to the highest standard.

Once the grains are sorted by length, infra-red Sortex machines are applied to separate dark and colored grains for further enhancement of the product. The rice, after passing through all the quality enhancing procedures, is transported to the silo bins for storage. Temperature in the bins is carefully controlled to maintain its freshness and ensure its highest standard of quality for export.

Metal detector machines include two sizes; small and big. Their main functions are as follows:-After the last stage of packaging, the products will be conveyed by conveyor belts through metal detector machines prior to container or cargo loading, to objectively detect ferrous or non ferrous materials, classified from their density into two groups, namely:-

Heavy metal : not iron, possesses less density than 5kg/dm3, such as copper, lead, zinc or tin. Light metal: not iron, more density than 5kg/dms3, such as aluminum, magnesium, and stainless steel.

Should the metal detector machines encounter with such metals or adulterated items, the warning sound and signal would be alarmed at the same moment when the conveyor belts stopped. However, if neither metals nor extraneous materials are detected, the products will pass through the machines normally.

1. Small sized machine (for 500 g. – 20 kg. product)

- Capable to detect 1.5 mm. ferrous, 1.5mm, non-ferrous materials, and 2.0 mm. stainless steel.

- Reject Type: Stop alarm

2. Big sized machine (for 5 kg. – 50 kg. product)

- Capable to detect 2.7 mm. ferrous, 4.0 mm. non-ferrous materials, and 4.0 stainless steel.

- Reject Type: Stop alarm
