The rice that is sold in the market and reaches consumers for cooking and consumption is very different from the paddy grains that reach a mill for processing. Raw rice is cleaned, shelled, polished, whitened, sorted, and graded before being packaged and sold. The process of shelling or hulling paddy is an especially crucial step in making the grains suitable for consumption by removing the protective and hard outer layer (called husk). Years ago, this was mainly done manually and took time. However, rice huller machines have transformed the process completely today.
To know more about what a rice huller is, the different types available, and why they are used in rice mills, read on.
Rice Huller Definition
A rice huller is essentially a type of machine that removes the husk or outer shell of raw rice grains by leveraging automation. It features a hopper through which raw grains are fed into the machine. And then a couple of rollers that are abrasive and rotate in opposite directions at different speeds, squeeze, rub, and de-husk the paddy. Afterwards, the hulled grains and husks head to separate bins for further processing and recycling respectively.
Rice Huller Types
Hullers can be of different types to suit mills of various sizes, operational scales, budgets, etc. However, you can usually classify a rice mill huller in one of the following key categories:
- Manual: Manual rice hullers are either operated by hand or foot. The hand-driven ones generally mimic the rhythmic pounding of a mortar and pestle, while the foot-driven machines are inspired by bicycles or treadles. Both require time and effort and are usually suitable for small mills. Also, remember that you have a greater chance of breaking or damaging the grains with manual hullers.
- Pneumatic: These rice hullers use compressed air to de-husk large quantities of paddy at superfast speeds. They are ideal for large-scale or industrial-level processing and have high efficiency. You can reduce grain breakage significantly, too, with pneumatic hullers. Such machines might feature both manual and automatic modes and have sensors for triggering the de-husking process automatically.
- Electric: Also known as motorised rice hullers, these machines run on electricity and require minimal human intervention. They are efficient, easy to operate, highly productive, and come in various sizes too.
While shopping for a rice mill huller, also consider factors like the type of grain, features, safety standards, and ease of maintenance, no matter which model you go for.
Why is a Rice Huller Used in Rice Mill Plants
Now that you know what a rice huller machine does, find out why it is used in all modern rice mills.
1. Saves Time
This is one of the biggest benefits of a rice huller. It de-husks raw rice grains much faster than if you had employed human labourers for the task. You can use this time to focus on other important chores requiring human judgment or decision-making instead.
2. Reduces Labour Cost
Since you don’t need many operators to run and supervise automatic and feature-rich rice hullers, you can save quite a bit on labour costs. The best machines are easy to maintain as well, which means you won’t need too many people to keep them in good shape for years.
3. Ensures Better and Consistent Quality
A rice huller minimises the damage or breakage of grains and improves the quality of the final, processed version in terms of texture, colour, shape, etc. You can also maintain consistent quality for every batch of paddy hulled.
4. Increases Output
Modern hullers easily process large amounts of rice in little time, which means your throughput and output shoot up. Not only does the overall efficiency of your mill increase, you sell more, rake in greater revenue, and even augment your profit margin since your operational costs are low.
5. Boosts Business Growth
To stay competitive in a dynamic business landscape, you must embrace technological advancements. And it’s no different when it comes to rice milling. Rice hullers give you an edge over traditional or labour-intensive mills and improve your profitability, which means you can easily invest towards growing your business fast or setting up new facilities. Your market reputation gets better, and you also get to instil confidence in both suppliers and consumers. All of that is conducive to long-term expansion.
Conclusion
So, by now, you understand what a rice huller machine is, the main types you can pick from, and why it can make a world of difference to your mill. Before putting your money on one, though, set aside time to assess your needs, fix a budget, and research multiple brands or manufacturers. Study different models and compare them based on features, specifications, durability, size, price, etc. Opt for a machine that comes with after-sales support and a satisfactory warranty too. Go through customer reviews and settle for a brand that is reputed and can offer training as well as technical troubleshooting if required.
