Fortified Rice Making Machine

• A Fortified Rice Kernel (FRK) machine is essentially an extruder that takes rice flour and a premix of vitamins, minerals, and other nutrients, mixes them under high heat and pressure, and then extrudes them through a die to form kernels that look and cook like rice.
• Core Components: Key parts include a feeding system, twin-screw extruder, heating/cooling zones, and dies, often with a connected air conveyor and packaging system.
• Function: It simplifies adding essential nutrients to combat malnutrition, ensuring uniform distribution and stability of added vitamins.

Typical Specifications

• Capacity: Varies widely, from 100-120 kg/hr for smaller units to 300-600 kg/hr or more (up to 8 tons/hr) for industrial setups.
• Power: Requires significant power, often 3-phase electric, with motor power ranging from 3 HP (for smaller models) to 70-116+ kW for higher capacities.
• Material: Contact parts are typically food-grade Stainless Steel (SS 304 or SS 316) for hygiene.
• Automation: Usually fully automatic, using PLC/inverter controls for precise ingredient ratios (e.g., 1:100) and smooth operation.
• Key Features: Non-residue design, forced lubrication, automatic flow correction, and one-button cleaning for efficiency.

Working Principle (Extrusion)

1. Mixing: Rice flour and nutrient premix are fed into the extruder.
2. Extrusion: Twin screws mix, shear, and homogenize the mixture under high pressure and temperature, forming a paste.
3. Shaping: The paste is forced through die holes, puffing and cooling rapidly to form kernel shapes.
4. Drying/Cooling: Kernels are then dried and cooled before packaging.
