Complete Guide to Rice Cleaning Machines: Working, Benefits & Types
As one of the largest global producers of rice, India has a responsibility to make sure rice is cleaned to perfection before landing on our tables. Dust, stones, husk, straw, and other unwanted materials must be removed, and for that, the industry has to use special machines. Without these machines, the process takes much longer and is far more difficult. This guide will help you understand how Rice Cleaning Machines work and the various benefits they offer.
What Is a Rice Cleaning Machine?
Rice cleaning machines improve the quality of unfinished rice by removing all the unwanted elements. This process is vital to ensure that the remaining rice is ready for the next phase of processing. Rice used to be cleaned by hand, which was time-consuming and tedious. Thankfully, the industry uses machines for this process now. There has been an improvement and increase in rice cleaning and grading machines by companies such as Classic Agro Industries, which then enables rice millers to use their time more efficiently.
How Does a Rice Cleaning Machine Work?
The working principle of a rice cleaning machine is quite simple yet efficient. The machine uses a combination of air, vibration, and sieves to separate good grains from impurities. Here’s a step-by-step explanation:
- Feeding:
The raw rice or paddy is fed into the machine through a hopper. - Air Separation:
A powerful blower creates an airflow that removes light impurities such as dust, husk, straw, and chaff. - Sieving Process:
The grains then move over vibrating sieves or screens. These sieves are designed with different hole sizes to separate particles based on size and weight.
- Small dust or sand passes through the sieve.
- Large impurities like stones or straw are removed from the top.
- Only clean rice passes through to the next stage.
- Stone Removal (Optional):
Some machines also include a destoner that separates stones and heavier particles from rice using differences in weight and density. - Output:
Finally, the cleaned rice is collected and ready for further processing, like polishing, grading, or packaging.
Benefits of Using Rice Cleaning Machines
Using a rice cleaning machine offers several benefits to mill owners and processors. Let’s look at the key advantages:
Improved Rice Quality
Clean rice looks better, cooks better, and has a higher market value. The cleaning process ensures uniform grain quality and removes unwanted particles.
Time and Labor Saving
Manual cleaning is slow and tiring. A machine can clean large quantities of rice in minutes, saving time and reducing the need for manual labor.
Higher Efficiency
Modern machines have advanced features that ensure almost complete removal of impurities, resulting in better yield and less wastage.
Hygienic Processing
Mechanical cleaning reduces human contact, which helps maintain hygiene standards, especially important for food-grade products.
Cost-Effective Operation
Although there is an initial investment, rice cleaning machines quickly pay for themselves through higher output, reduced labor costs, and improved product quality.
Types of Rice Cleaning Machines
There are different types of rice cleaning machines available depending on the size of the mill and the kind of cleaning required.
Pre-Cleaner Machine
Used before milling, the Pre-Cleaner Machine removes large impurities such as straw, leaves, and stones from the raw paddy.
Vibro Cleaner
This machine uses vibration and sieves to separate fine dust and broken grains. It is ideal for high-capacity mills and ensures uniform cleaning.
Destoner Machine
A destoner removes heavier impurities like stones, metal pieces, or glass. It works based on the principle of the density difference between grains and stones.
Aspirator or Air Cleaner
It uses airflow to remove lighter impurities such as husk or dust. Often, it is combined with other cleaning units for better performance.
Combined Cleaning Units
Some modern systems combine all these processes—air cleaning, sieving, and destoning—into one compact unit for higher efficiency.
