Introduction

Modern grain and seed processing needs clean, safe, and well-graded products. Farmers, mill owners, and food processors all want better quality with less waste. This is where a Destoner Cum Grader Aspirator becomes very useful. It is a single machine that does three important jobs at the same time – removing stones, grading grains, and cleaning with air.

In this blog, we will explain everything about this machine in very simple English. You will understand how it works, where it is used, its benefits, parts, maintenance tips, and how to choose the right one.

Note :- Destoner Cum Grader Aspirator is used to clean and grade grains by removing stones, dust, and other unwanted particles. It helps improve product quality by separating light and heavy impurities in one smooth process. This machine is widely used in food processing plants to save time and get cleaner, well-graded output.

What Is a Destoner Cum Grader Aspirator?

A Destoner Cum Grader Aspirator is a multi-purpose machine used in grain and seed cleaning plants. It helps remove unwanted materials like stones, dust, husk, and broken grains. At the same time, it separates grains by size and weight.

This machine is widely used because it saves time, space, and money. Instead of using three separate machines, one machine does all the work.

Why This Machine Is Important in Grain Processing

Clean grains are very important for food safety and quality. If stones, dust, or light impurities are mixed with grains, they can damage machines and reduce product quality.

Using a Destoner Cum Grader Aspirator helps:

• Improve grain quality

• Increase product value

• Reduce machine damage

• Save labor and energy

This makes it a smart choice for small and large processing units.

Main Functions of a Destoner Cum Grader Aspirator

This machine works in three main ways. Let us understand each function clearly.

Destoning Function – Removing Stones and Heavy Impurities

Stones and heavy particles are very dangerous in grain processing. They can break milling machines and cause losses.

The destoner part of the machine removes:

• Stones

• Mud balls

• Glass pieces

• Heavy metal parts

It works by separating grains and stones based on weight and airflow.

Grading Function – Separating Grains by Size

Grading means sorting grains by size. Bigger and uniform grains are better for selling and processing.

The grader part helps:

• Separate big grains from small ones

• Remove broken grains

• Improve uniformity

This is useful for rice, wheat, maize, pulses, and seeds.

Aspirator Function – Removing Light Impurities

The aspirator uses air to remove light materials. These materials are lighter than grains.

It removes:

• Dust

• Husk

• Chaff

• Light straw

This improves cleanliness and gives a better final product.

How a Destoner Cum Grader Aspirator Works

Understanding the working process is very easy if we break it into steps.

Step 1: Feeding the Raw Material

Grains are fed into the machine through an inlet. This can be done manually or with a conveyor.

Step 2: Air Cleaning by Aspirator

As soon as grains enter, air is blown through them. Light materials like dust and husk are carried away by airflow.

Step 3: Grading Through Sieves

After air cleaning, grains pass through grading sieves.

• Large grains stay on top

• Medium grains pass through

• Small and broken grains fall below

Each size is collected separately.

Step 4: Destoning Process

Now the grains move to the destoner section.

• Heavy stones move in one direction

• Clean grains move in another

At the end, you get stone-free and clean grains.

Types of Materials Processed by This Machine

A Destoner Cum Grader Aspirator can handle many products.

Common Grains and Seeds

• Wheat

• Rice

• Maize

• Barley

• Oats

Pulses and Seeds

• Chickpeas

• Lentils

• Peas

• Sunflower seeds

• Soybeans

This makes the machine very flexible for different industries.

Industries That Use Destoner Cum Grader Aspirator

This machine is used in many industries.

Food Processing Industry

Food factories use it to ensure clean and safe raw materials.

Flour and Rice Mills

Mills use it to protect machines and improve flour and rice quality.

Seed Processing Units

Seed companies use it to get clean and uniform seeds for farming.

Animal Feed Plants

Clean grains improve feed quality and animal health.

Benefits of Using a Destoner Cum Grader Aspirator

There are many benefits of using this machine.

Saves Time and Labor

One machine does the work of three machines. This reduces handling and labor costs.

Improves Product Quality

Clean, graded, and stone-free grains are better for selling and processing.

Reduces Machine Damage

Removing stones protects grinders, rollers, and cutters from damage.

Easy to Operate

Most machines are simple to run and need minimal training.

Cost Effective

Lower energy use and less manpower make it a cost-saving solution.

Main Parts of a Destoner Cum Grader Aspirator

Knowing the parts helps in better use and maintenance.

Feeding Hopper

This is where raw material is loaded.

Aspirator Fan

The fan creates airflow to remove light impurities.

Grading Sieves

These sieves separate grains by size.

Destoning Deck

This part separates stones using vibration and airflow.

Motors and Frame

The motor runs the machine, and the frame holds all parts together.

Maintenance Tips for Long Life

Proper care increases machine life and performance.

Regular Cleaning

Clean sieves and air ducts daily to avoid blockage.

Check Moving Parts

Lubricate bearings and check belts regularly.

Inspect Airflow Settings

Correct airflow is important for good cleaning.

Replace Worn Parts

Change damaged sieves and rubber parts on time.

Common Problems and Simple Solutions

Problem: Stones Not Removing Properly

Solution:
Adjust airflow and deck angle.

Problem: Too Much Grain Loss

Solution:
Reduce air speed and check sieve size.

Problem: Dust Coming Out

Solution:
Check fan and dust outlet connections.

How to Choose the Right Destoner Cum Grader Aspirator

Buying the right machine is very important.

Capacity Requirement

Choose based on how much grain you process per hour.

Type of Material

Different grains need different sieve sizes and airflow.

Space Available

Make sure the machine fits your plant layout.

Power Consumption

Check motor power and energy usage.

Build Quality

Strong steel body lasts longer and works better.

Installation Tips for Best Performance

Level the Machine Properly

A flat surface ensures smooth vibration and separation.

Correct Air Duct Connection
