Understanding the Rice Whitener
What is a Rice Whitener?
A rice whitener is a specialized machine designed to remove the bran layer from brown rice, resulting in white rice. This process not only enhances the aesthetic quality of the rice but also improves its shelf life. Different types of rice whiteners are available, each tailored for specific milling needs and grain types.
How Does a Rice Whitener Work?
Rice whiteners operate on the principle of friction and abrasion. The rice grains are passed through rotating iron and emery rolls, which rub against each other and the machine’s internal components. This action effectively removes the bran layer. Aspiration systems may also be integrated to cool the rice and minimize breakage.
Types of Rice Whiteners
Vertical Rice Whitener
Vertical rice whiteners, such as the ones offered by satake-usa.com and buhlergroup.com, employ a top-to-bottom processing principle. This design allows for efficient bran removal while maintaining high yield rates. Their compact size and advanced technology make them suitable for modern rice mills.
Horizontal Rice Whitener
While less common, horizontal rice whiteners utilize a different design that can be advantageous for certain rice types. The configuration of these machines may lead to different friction dynamics, affecting the quality of the milling process.
Specialty Rice Whitener
Machines like the Maxtex Rice Whitener are designed specifically for long-grain varieties, such as Basmati. These whiteners often include unique features that facilitate optimal polishing without damaging the delicate grains.
Key Features of Rice Whiteners
Adjustable Milling Degree
Many modern rice whiteners come equipped with an adjustable milling degree feature. This allows operators to customize the level of whiteness based on the rice type and customer requirements. For instance, the VTA from SATAKE Group provides an automatic milling degree controller as an option.
Easy Maintenance Design
Maintenance is crucial for the longevity and efficiency of any machinery. Models like the TopWhite BSPB have a “lift-away” design for screens, making changes quick and straightforward without removing the entire frame.
Cooling and Aspiration Systems
A critical feature in rice whiteners is the cooling and aspiration system, which reduces grain breakage during the whitening process. This system also helps in the removal of bran from the chamber, ensuring a clean and efficient operation.
