I. Introduction of Nutrient Fortified Rice

Fortified rice (also called enriched rice) is produced by adding certain nutrients to ordinary rice/broken rice ingredients in accordance with the corresponding fortification standards. 

Then it is through extrusion process and drying process.

The food grade enriched rice is produced to meet human body’s needs for specific nutrients.

Super fortified rice will mix with ordinary rice in a certain ratio to cook, such as 1:300, 1:200, etc.

Twin-screw extrusion process is an important method for fortified rice manufacturing plant.

With the fortified rice extruder, the raw material can be whole white rice or broken rice-the by-product produced during the rice milling process.

III. The General Flow Chart for Nutrient Fortified Rice

• Step 1: Crushing
• Step 2: Mixing (rice flour and desired nutrient flours)
• Step 3: Extrusion & shaping
• Step 4: Drying
• Step 5: Screening (to remove small particles)
• Step 6: Measuring and packing

The brief working process of fortified rice machinery plant are as follows:

• The rice is crushed into finer particles of a specific size. Particles that are over coarse are not conducive to hydration, and particles that are over fine can cause clumping.
• After the rice grains are evenly mixed with the nutrients that meet the nutritional standards, they are automatically added to the fortified rice extruder at a constant speed.
• Extrusion process must perform many phenomena in a short period of time under controlled, continuous, and steady-state conditions. First, the mixed raw materials are conditioned and tempered, then cooked and kneaded to form dough of desired characteristics. The design of the process and the setting of equipment parameters must allow the starch to be cooked well without puffing. More importantly, the fortified nutrients are not destroyed but well fixed in the rice starch.
• The rice starch dough is extruded into rice-shape through a forming die. The extruded rice granules are as close to rice as possible in smell, taste and texture, and already evenly packed with expected rich nutrients.
• After drying in the dryer, the weighing and packaging process are completed by the automatic packing process.

• According to the different added nutrients, the fortified rice machinery plant can produce different nutritionally fortified rice. Such as vitamin fortified rice, mineral nutrient fortified rice, protein nutrient fortified rice, compound nutrient fortified rice, etc
• The width and length of the extruded rice grains depend on the mold, such as 0.5-3.5mm wide and 4-10mm long, etc. The mold can be customized freely.

Processing potential

• In addition to the artificial/fortified rice, by changing the formula and extrusion parameter settings, the fortified rice machinery plant can also process various analog rice like corn analog rice, kudzu root analog rice, sago analog rice, etc.
