In Vietnam, soybean cleaning and impurity removal equipment primarily serves its rapidly expanding livestock feed processing industry and traditional soybean product processing . Due to Vietnam’s limited domestic soybean production (estimated at approximately 40,000 tons in fiscal year 2026/27), and its heavy reliance on imports from countries such as the United States and Brazil, the equipment is mostly used for secondary cleaning after bulk unloading at ports and for further processing in factories. 
I. Commonly Used Equipment for Cleaning and Removing Impurities from Vietnamese Soybeans
The soybean cleaning process in Vietnam typically includes three stages: pretreatment, fine sorting, and grading. Commonly used equipment includes:
Pre-Cleaner : Used to initially remove large impurities (such as clods of soil, straw fragments), dust, and skins from soybeans.

Destoner : Specifically designed to remove heavy impurities such as stones and mud lumps similar in size to soybeans by using density differences, ensuring the lifespan of subsequent pressing or grinding equipment.

Vibration grader/sizer : Uses screens with different apertures to grade soybeans according to their size and shape, while removing broken particles and fine impurities.

Gravity Separator : Selects seeds based on density, removing insect-damaged, moldy, empty, and lightweight impurities.

Color sorter : It uses optical technology to detect and remove discolored grains, damaged grains and off-color impurities. It is a key piece of equipment to improve the marketability and food-grade quality of soybeans.
Magnetic Separator : Installed in the conveying process, it is used to remove metal residues mixed in with soybeans.
II. Characteristics of Local Crops in Vietnam
Vietnamese agriculture is transitioning from traditional farming to green, high-value exports, and its main crops exhibit the following characteristics:
1.Advantageous crops that are highly dependent on exports :
oCashews : Vietnam is the world’s largest exporter of cashews, accounting for more than 50% of global processing volume.
oRice and Coffee : China has consistently ranked second in the world in rice and coffee exports, with Robusta coffee being a high-yield specialty variety in the south.
oTropical fruits , such as dragon fruit, durian (export value exceeded US$3 billion), and mango, are diverse in variety and have significant price competitiveness.
2.Regionalization and decentralization characteristics :
oCore production area : The Mekong Delta is the core, contributing 50% of the country’s rice, 65% of its aquatic products, and about 70% of its fruit production.
oScattered planting : Farmland is scattered, similar to the small-scale farming model in Taiwan, which creates a great demand for small and medium-sized customized smart agricultural equipment (such as smart irrigation and small plant protection drones).
3.Soybean planting scale reduced, reliance on imports :
oDriven by economic considerations, local farmers are more inclined to grow higher-profit fruits and vegetables. Soybean planting area continues to decline (projected to drop to approximately 24,000 hectares in 2026/27), mainly concentrated in the northern region.
4.Transformation direction :
oWe are actively promoting the transformation to ecological, circular and digital agriculture , emphasizing product traceability and green sustainable value to meet the access requirements of high-end markets such as Europe and the United States.
