Instant Rice Processing Line
Instant rice production line is designed with high efficiency, stable quality and strong commercial performance. Manufactured from refined rice flour and optionally supplemented with whole grain blends or beneficial nutrients, it is processed using modern extrusion cooking method to restructure the starch matrix and generate homogeneous rice shaped kernels. Then the produced rice is stabilized by controlled drying processes such fluidized bed drying, microwave drying or multi-layer belt drying to reduce the moisture content and prevent starch retrogradation, which ensures a stable texture and extended shelf life.

Raw Ingredients Intake and Dosing
The ingredient mixing machine provides automatic feeding and dosing of different raw materials, assuring accurate formulation and dosage. The advanced control technology provides accurate proportioning to satisfy tight production tolerances and ensures high levels of precision and reproducibility throughout continuous operations.
Extruding
The raw materials undergo controlled shear, mixing and thermal cooking in a twin-screw extrusion system under high temperature and pressure. The screws rotate to plasticize and gelatinize the starch efficiently and the material is molded with precision dies to the desired shape and size to create a consistent product structure and quality.
Vibration Cooling
The vibratory cooling conveyor is designed specifically for handling pre-formed wet granules and prevents sticking and deformation during transfer. Material is advanced by controlled vibration for gentle handling and uniform separation. The longer cooling path improves the heat dissipation and the preliminary drying effect. The adjustable vibration frequency enables the flexible operation of different types of products and process conditions.
Pre-Drying
The combined action of mechanical vibration and air flow fluidization maintains the material in a homogeneous fluidized state, which allows for efficient heat and mass transfer for successful pre-drying. The moderate vibration and fluidization reduce mechanical stress and make the technology particularly ideal for handling fragile or breakage sensitive objects.
Drying
The dryer removes residual moisture from fortified rice kernels to reach target moisture for safe packaging, prolonged shelf life and consistent storage performance.
Cooling
The counterflow cooler uses a counter-current flow of ambient air and product to provide consistent, progressive cooling. This design lowers thermal shock and hence reduces the possibility of cracking and fine formation. The product is usually stored at 3–5 °C above ambient temperature after cooling, which is sufficient to ensure its stability for further handling and packaging.
