Production Process
for Corn Products

Kernel Journey

1

Grain Storage

Corn is stored in large silos where grain temperature is constantly monitored.
2

Corn Cleaning

To ensure that only whole kernels enter the milling process, corn is cleaned to remove foreign materials and damaged corn kernels.
3

Tempering Conveyor

To soften the germ and loosen the bran coat, cleaned corn kernels are moistened or “tempered”.
4

Degerminator

This milling device uses an abrading action to peel the bran coat and germ from the endosperm of the corn kernel. This splits the ”tail stock” (large endosperm pieces) from the ”thru stock” (hull, germ and smaller endosperm pieces).

Thru Stock Journey

1

Dryer/Cooler

To prevent condensation, heat is used to remove excess moisture from the stream. After this, cool dry air is used to aerate the product.
2

Gravity Table

This device uses the density difference between corn
germ and endosperm to further split the kernel into
separate components.
3

Reduction Roll

This is the first step in finer granulation wherein the endosperm is broken into smaller, more uniform sizes.
4

Sifter

This device is equipped with fine-meshed sieves or screens that use circular motion to separate smaller particles from
the larger ones.

Tail Stock Journey

1

Dryer/Cooler

To prevent condensation, heat is used to remove excess moisture from the stream. After this, cool dry air is used to aerate the product.
2

Aspirator

This device uses air flow to separate lighter particles (bran) from the heavier ones (endosperm), using the density differences and laws of aerodynamics.
3

Sifter

This device is equipped with fine-meshed sieves or screens that use circular motion to separate smaller particles from the larger ones.

Production Process
for Rice Products

1

Raw Rice Crop Intake

Receiving: Unloading raw rice crop from trucks.
Weighing: Measuring the quantity received.
Storage: Storing the raw rice crop in silos or warehouses.
2

Vibro Separator

Pre-cleaning: Removing large impurities such as straw and stones.
Separation: Separating smaller impurities using a vibrating screen.
3

De-stoner Machine

Feeding: Feeding raw rice crop into the de-stoner machine.
Stone Removal: Separating stones and heavy impurities using air and vibration.
4

Silky Machine

Feeding: Feeding raw rice crop into the silky machine.
Polishing: Removing the bran layer to give the rice a shiny appearance.
5

Color Sortex

Sensitivity: 1300 – 1500
Feeding: Feeding polished rice into the color sortex machine. Feeding Speed: 75 – 80
Sorting: Detecting and separating discolored or defective rice grains using optical sensors.
6

Roller Mill

Feeding: Feeding sorted rice into the roller mill.
Milling: Removing the husk and bran layers to produce white rice.
7

Plan Shifter

Feeding: Feeding milled rice into the plan shifter.
Sifting: Separating milled rice into different sizes and grades using a series of sieves.
8

Packing

Weighing: Weighing the final rice product.
Bagging: Packing rice into bags of specified weights.
Sealing: Sealing bags to maintain product quality and freshness.
9

Metal Detector

Feeding: Belt metal detector after packing with sensitivity of
Fe (Ferrous) - 3.0 mm
NFE (Non-Ferrous) - 3.5 mm
SS (Stainless Steel) - 4.0 mm
Detection: Detecting and removing any metallic contaminants.
10

Final Products

Rice Grits: Producing two grades of rice grits.
Rice Flour: Producing fine rice flour.

Production Process
for Biofuel Division

GrainSpan employs an advanced distillation system at the ethanol plant that optimizes grain-to-ethanol conversion with highest quality output. There is a rigorous quality control mechanism set-up to ensure consistent and reliable supply of top-tier ethanol.

Production Process
for DDGS

DDGS is a by-product of the rice-based and corn-based ethanol production. It is obtained using the same advanced distillation system and quality control mechanism that are used in the production of ethanol. However, it involves the additional step of drying the by-product to obtain DDGS.

Production Process
for CO2

Corn and rice milling processes release significant amounts of CO2 as a by-product. Instead of releasing this CO2 into the atmosphere, we capture and store it using advanced technology. This capture-and-storage process reduces our environmental impact apart from supporting a circular economy.
