About table paddy separator

Types of table paddy separators

The function of a table paddy separator is to distinguish between brown rice and unhusked paddy rice. However, there are various types of the separator with distinctive features and working principles.

  • Basic Separator: This standard model uses a slanted table and several vibrating trays to classify rice varieties or remove unwanted grains. Pan sizes, adjustability, and vibration frequency may vary with this separator.
  • Winnowing Separator: This separator separates lighter particles from denser ones using airflow. The paddy rice is placed on a slanting table, where wind blows from underneath, lifting the lighter particles, while the heavier ones remain. The latter falls into different collecting containers.
  • Modern Paddy Separators: These digital rice paddy separators have been automated for large-scale rice milling. They are usually fast, efficient, and less labor-intensive. On the other hand, they may have data tracking and storage, remote monitoring, and automated adjustment features.
  • Paddy Separators in Milling Machines:Some rice milling machines come with a built-in rice separator. Such a rice separator is typically small and compact to occupy minimal space and assist in streamlining the rice milling process. It may also be made to suit specific rice milling requirements.
  • Size and Adjustability:Separators may have different sizes and adjustability options. For example, some industrial-scale separators may be broader and more extensive than their small-scale counterparts. Furthermore, larger separators may have several separating tables for greater efficiency. Additionally, some separators may be adjustable to suit different rice varieties or grain features.

Specifications and maintenance of table paddy separators

  • Capacity: The separator's capacity can depend upon its size and the power of its motor. Separators that use electromagnetic motors can process around 15-40 tons of paddy rice per hour.
  • Dimensions: An average paddy separator's dimension is usually depicted in length, breadth, and height. Depending on the design, it can be approximately 180 cm in length, 180 cm in breadth, and 300 cm in height.
  • Weight: The separator's weight typically depends on its capacity and the materials used in manufacturing. The foam, wooden, and metallic paddy separator, for example, may weigh up to 2000 kg.
  • Voltage and Power: A separator's motor runs on electricity, diesel, or gasoline. For instance, the voltage of an electric separator will be from 220V to 440V. Its power usage will vary from 2 hp to 20 hp, depending on the voltage.
  • Materials: Paddy separators are manufactured from different materials, such as stainless steel, aluminum, iron, etc.

Maintenance:

  • Cleaning: Clean the table by removing grains, husks, etc., after separating the rice. Use mild detergent and warm water to wash the conveyor belts andslides. Use compressed air or vacuum cleaner to remove the dust that accumulates in the electric motor or separator fan.
  • Lubrication: Lubricate the bearings while removing those that require lubricating. Make sure to apply lubricating oil to the slides and conveyor belts too.
  • Inspection: Check all the belts and their adjusting parts for tightness. Inspect the bearings for any sign of wear and tear. Check also the electric motor fans to see if they are working properly.
  • Repairs: If the bearings show any sign of damage, replace the old ones with new. Repair or replace the conveyor belts if they get torn. Seek professional help if there's an issue with the electric motor or fan.

Scenarios of table paddy separators

  • Rice milling plants

    In rice milling plants, the table rice separator is placed after the rice milling process and before packaging. Its work is separating rice grains according to size. Smaller, broken grains are in a separate output stream. The final rice product is clean, high quality, and ready for consumers.

  • Food processing companies

    Food processing companies use table separators to sort and size different foods. For example, in a flour mill, a separator can be used to separate coarse flour from refined flour. Food companies can make processed foods of different grades by using table separators.

  • Laboratories and research institutes

    In laboratories and research institutes, table separators are used for particle analysis and classification. Rice tables with multiple tables are commonly used in studies examining grain characteristics, including size, shape, and weight. The data collected can be used to develop new milling and separating technologies, improve grain quality, and optimize processing techniques.

  • Agricultural co-operatives and small farms

    Agricultural co-operatives and small farms can also use table separators to process and market their crops. After harvesting and initial processing, these farms can use table separators to improve product quality before selling it directly to customers or through retail channels.

  • Export and import companies

    Export and import companies can use table separators to meet specific standards set by the importing country. It may be required to remove impurities, foreign materials, and unwanted particles to satisfy the customers' demands and regulations; hence, table separators come in handy.

How to choose paddy separators

Choosing the right rice separator for the business involves considering the various types, features, and specifications to ensure that it meets one's rice milling needs efficiently and economically.

  • Separator type familiarization:

    One should get familiar with the working principles and features of the commonly used separators, like the air-flow separator or vibrating separator. Each has distinct advantages, so select one that matches rice grain quality and processing requirements.

  • Consider the rice milling scale:

    The separating capacity should match the rice milling scale. For large-scale separation, industrial or air-flow separators with high separation efficiency are more appropriate. Small vibrating tables may work for smaller, decentralized rice processing operations.

  • Pay attention to separation efficiency:

    It is the crucial function of the separator. Choose the separator with high separation accuracy and efficiency to minimize rice grain mixture loss and maximize rice product output. Some models provide data on separation efficiency, and one can refer to these figures when selecting.

  • Convenient operation and maintenance:

    Separating rice is a frequent work in rice milling. Choose a separator that is easy to operate and maintain so staff can familiarize themselves with it and carry out routine maintenance on time. Also, ensure that the required maintenance parts and tools are available.

  • Durability and build quality:

    The rice separator's work environment is dusty and high-pressure, so it needs a durable model. Select those with sturdy build quality, which can resist wear and damage, and ensures a long service life.

  • Energy efficiency:

    Energy separation consumes a significant amount of power. Choosing a model with low power consumption helps control operating costs. Some advanced energy-saving models can substantially cut electricity use.

  • Adaptability:

    As the varieties of rice may be changed in the future, it is better to select an adjustable model that can alter its working parameters to handle different rice varieties and qualities.

  • Separators come with extra functions:

    Some rice separators offer additional features, such as dust removal and storage bin discharge. These functions can satisfy several processing requirements and improve overall rice milling efficiency.

  • After-sale service and support:

    Select a supplier who provides fast after-sales support, technical consultation, and spare parts service. A helpful after-sales team can guide separator use, maintenance, and troubleshooting.

Table paddy separator FAQ

Q1: Which separator is used for paddy rice?

A1: The paddy rice separators are the rice mill's separating devices. The aim of separating different grains or chaff is to produce homogenous rice that is saleable. The separators can be cyclones, air tables, vibrating screens or planes separating rice from paddy husk.

Q2: How does a paddy separator work?

A2: Paddy separators work by taking advantage of the shape and size discrepancies among various rice grain types. The materials have different velocities as they move over the inclined shaking table. The framework slopes downwards and shakes sideways, thereby splashing the materials. The smaller and lighter objects like rice move faster and are discharged at the separator's bottom end, while the larger and heavier ones like stones and impurities are removed at the separator's side.

Q3: Which method is used for the separation of rice?

A3: The most common separation methods include air classification, gravimetric separation on tables and disc separators, and combined air and sieve separations.

Q4: What is the difference between husk and paddy separators?

A4: The main difference between husk and paddy separators is their purpose and functioning. Husk separators are designed to separate the husk, i.e. the outermost dry part covering the paddy grain, from the paddy grains. Conversely, paddy separators are devised to separate paddy grains from other cereal grains.
