Hector separators
The Hector separator operates on the principles of size, weight, and air floatation difference. Generally, it comprises a feed hopper, a distribution device, a deck table, a fan, a dust collecting system, and a storage bin. Initially, the paddy is fed into the separator via the feed hopper. Then, the distribution device evenly spreads the grains on the deck table, which contains different-sized screens. Due to the difference in size, weight, and air floatation of the grains, the good-quality grains fall through the screens, while the bad-quality ones slide off the sides. Finally, the good and bad grains are collected separately into the storage bin.
Whiteners with gravity separators
Whiteners with gravity separators combine the functions of degerming, refining, and separating by gravity into a single unit. This integrated design streamlines the milling process and reduces the need for separate pieces of equipment.
Separator tables
Separator tables are flat, vibrating tables with a deck covered in net-like fabric. The separator's airflow, tilt angle, and vibration frequency can all be adjusted to change the separation process.
Paddy gravity separators
Paddy gravity separators are specifically designed to separate paddy rice from other grains based on its higher size and weight. Usually, they are the initial step in the rice separation process.
Multiple-deck separators
Typical gravity rice separator has the single deck. But there are also separators with a multi-deck design. Such models increase productivity and separate rice according to different criteria.
Specifications for rice gravity separators can vary depending on the model and the manufacturer. The following are some common specifications for rice gravity separator machines.
Product dimensions
A rice gravity separator machine's dimensions will depend on the model and design. For the separator table and deck, dimensions can usually range from 1m to 3m in length and from 0.5m to 1.5m in width.
Working capacity
The working capacity of rice gravity separators refers to the quantity of rice they can handle per hour. This capacity may vary depending on the rice separator model. The working capacity can range anywhere from 200 to 500kg/h for small models and up to 1,500 to 2,000kg/h for larger industrial models.
A separate deck and table's slope angle and air pressure
The separating slope is the angle at which rice grains are dispersed on the deck or table. This slope varies depending on the rice separator model. The air pressure or volume refers to the amount of air flowing through the separation deck or table. This parameter determines how rice grains are blown and separated based on weight differences. The separator deck's or table's slope and air pressure can be adjusted to achieve the desired separation results.
Power Requirement
A rice gravity separator's power requirement indicates the motor's power rating that drives its vibrating mechanism and air blower. Depending on the model, this may range from 0.5 to 5kw.
Proper maintenance of rice gravity separators is important for ensuring their longevity and effective separation performance.
Regular Cleaning
Regular cleaning of the separator is necessary to remove any rice grain residue, dust or dirt build-up. Cleaning helps keep the air passage unblocked to achieve good separation results.
Daily Water Washing
At least once a day, users should flush the separator with a steady water flow. The flushing provides a hygienic condition for rice grain separation and prevents the spreading table and deck from being partially clogged with rice remains and debris.
Weekly Dry Cleaning
Besides daily water flushing, users should dry clean the equipment weekly by using a high-pressure air blower to eliminate residues and dirt that cannot be removed through water cleaning.
Gravity separators for rice can be used in a variety of industries and applications. Here are some of them:
Agricultural Companies and Farmers
Separators can be used on small-scale and large-scale rice and grain-producing farms. Farmers can use them to separate undesirable rice or grain by-products from quality harvests before selling or consuming them.
Rice Mills and Processing Plants
Rice gravity separators are probably the most commonly used in rice mills. Rice mills employ this machine during the final or post-processing stages of rice milling to achieve the utmost purity and high-quality rice. Separators can also be used in other grain processing facilities to separate rice from other grains or non-desirable rice by-products.
Food Production and Packaging Companies
Food production and packaging companies that deal with rice or grain products can also make use of rice gravity separators. The machines can be used before a Rice-A-Roni or other grain food product hits the supermarket shelves to ensure only rice makes it into the packaging.
Poultry and Livestock Farms
Poultry and livestock farms that use grains as feed can also benefit from grain separators. The separator can be used to eliminate unwanted grains or rice from the feed, ensuring only quality separators make it into the livestock's diet.
Research and Educational Institutes
Scientific research institutes or universities studying grain or rice may need to use a gravity separator to carry out some experiments. These institutes may want to examine the non-desirable grain or rice by-product's properties or conduct tests on the impact of different rice or grain mixtures.
Home Cooks and Chefs
Separators at a small scale can be used by home cooks or professional chefs. They may use a small gravity rice separator to create a special dish that requires specific types of grains, rice, or flour!
The following tips will help stakeholders like grain mill owners and rice processing plant managers make informed decisions when buying rice gravity separators.
Determine material compatibility
Separator machines for rice are made with different separator trays' construction materials. Buyers must ensure that the separation tray's material can withstand the rice's separating needs. What mill owners usually consider is the tray's construction material. Steel trays, especially stainless ones, offer durability and resistance to corrosion, ensuring a consistent separation quality over time.
Understand working mechanism
There are different types of rice gravity separators on the market, each with a unique working mechanism. Buyers must study the working mechanism of each separator type and understand how it works. Automation level, adjustment features, and operator expertise requirements are also factors to consider when deciding which separator to buy and use.
Focus on separation efficiency
Different rice gravity separator machines have different separation efficiencies. When buying, rice business owners and millers should go for models with proven separation efficiency. An effective rice separator will not just separate different grains, but it will also have features that help fine-tune the separation process to achieve the desired purity levels.
Consider adjustable features
Some rice gravity separators have adjustable features that allow fine-tuning separation based on grain characteristics. When buying, rice mill owners should go for models with adjustable features like slide angles, slopes, and air-flow rates. This adjustability grants operators control over the separation process to achieve the desired outcome.
Check the separator's air requirement
Rice separator machines function well when there is sufficient air pressure to separate grains. While it is ideal to choose gravity rice separator machines that work well with low air pressure, users must see that the air requirements of the separator matches the capabilities of their air supply system.
Maintenance and servicing
Gravity rice separators require regular maintenance to sustain their separation capabilities and efficiency. Buyers should go for models that have widely available spare parts. Also, consider the servicing needs of the rice gravity separator. A suitable service provider can attend to the machine and ensure it's working optimally all through its lifespan.
Understand the separator's capacity
Rice separator machines have different processing capacities. Rice mill owners should match the separator capacity with the rice separator workflow and grade separation needs. Failing to do this can result in bottlenecks in rice processing and inefficient separator use.
Q: What kind of rice separator is the best?
A: A high-performance rice gravity separator, such as the all-stainless steel model with a 6,000 kg/h throughput, would be among the best options. Cotton and wheat are also suitable for an optional feed. The rice separator should have various adjustable rice separator screens and a powerful 7.5 kW electric motor driving the fan.
Q: How does a rice gravity separator work?
A: A rice gravity separator works by using a combination of air blow, vibration, and screening to separate different kinds of grains, such as rice, wheat, and cotton. While vibrating, the separator's screens allow the lighter impurities, including rice husks and sand, to pass through. The electric fan blows air at high pressure, which helps separate lighter impurities from the heavier good grains. The separator's deck slope and vibration frequency can be adjusted to improve the accuracy of separation.
Q: Is a rice separator the same as a rice mill?
A: No, a rice separator is not the same as a rice mill. A rice gravity separator is used to separate rice grains from other lighter impurities, while a rice mill's primary function is to remove the husk from paddy rice and separate white rice from it. A rice mill produces rice, whereas a rice separator refines rice to separate out inferior grains and other impurities.
Q: Can air density separators be used instead of gravity rice separators?
A: Air separators are often used to classify materials that have little to no weight differences. Therefore, they are not a suitable substitute for a gravity rice separator. Rice grains have different weights and densities. A rice gravity separator separates impurities based on their weight differences concerning rice grains. An air separator works differently by using air pressure to separate materials of different sizes and shapes.
