Stoner destoner

Types of stoner destoners

Astononer/destoner is a mechanical device for separating undesirable and unwanted extraneous materials like stones, metals, and other non-food items from agricultural produce such as grains, pulses, rice, and much more. Various types of stoner destoners use different working principles to separate unwanted materials from food items.

• Gravity tables: It is perhaps the most common type of stoner destoner. A typical gravity table would have an air blower and an adjustable shaking table. The air blower creates an air cushion that separates light materials like husks, straws, and any unwanted item. Adjustment of the shaking tables helps the device to separate objects depending on sizes and weights. Normally, lighter things float above the surface while heavier ones stay below and are regarded as the final product. Separating unwanted objects using a gravity table is quite effective, but the tables themselves can be damaged easily by water.
• Air classifiers: Like gravity tables, air classifiers also use the principle of buoyancy to separate materials. Air classifiers boast an engine and an air duct that blow air into the classifier, creating an air cushion. Once the air is blow into the classifier, the weight and size of different materials come into play, and various objects find their way into the oncoming chutes. Light materials are lifted by the force of air into the chutes, while heavier ones drop down. Air classifiers work well in separating grain from dry leaves, stems, and other light materials.
• Magnetic separators: Magnetic separators are often used in grain processing industries. They are specifically meant for the separation of metallic objects like nails, scale, wires, and any other metal contaminants. The device is fitted with strong magnetic plates or rods that attract and hold magnetic materials. Once the grain has been processed and the metal contaminants stuck to the magnetic separators, the magnetic plates are cleaned manually. Then, the unwanted metal contaminants are discarded.
• Hopper magnets: Like magnetic separators, hopper magnets are used to separate grains or food items from metal contaminants. Unlike magnetic separators that filter at different points during the processing, hopper magnets are usually located at the bottom of hoppers or storage units. Because of the force of gravity, all food items in the hopper will pass on top of the magnets. The magnetic force will then attract metal contaminants, which will remain stuck to the magnet until it is cleaned.
• Destoner separator: It is another subsection of stoner destoners that is capable of separating stones, mud balls, and other undesirable heavy materials. The working principle of a typical destoner separator involves the use of a vibrating paddle and air blow. The vibrating paddle helps to separate materials depending on size and weight. Heavier particles such as stones drop in the designated area, while light materials float away in the air.

Specifications & Maintenance

The stoner destoner comes with various specifications. They are often compatible with different raw materials and can be effortlessly integrated into existing production lines.

• Throughput:

  It refers to the amount of product the machine can process per hour. For industrial-scale models, the typical throughput can range from 1 ton to 10 tons per hour, depending on the design and size of the machine.

• Airflow:

  Airflow is an important parameter, as it impacts product separation. The airflow generated by the machine is typically measured in cubic feet per minute (CFM). Generally, the CFM of an industrial-scale machine may range from 500 to 5,000, depending on the size and power of the fan.

• Noise level:

  The noise level is measured in decibels (dB). For many industrial-scale devices, the noise level can range from 70 to 90 dB, depending on the design.

Maintenance

It is paramount to conduct regular maintenance on the stoner destoner so as to ensure that it operates efficiently over a long time. With regular maintenance and care, the stoner destoner can work optimally for a long time.

• Inspection: Operators should regularly inspect the machine for any signs of damage or wear. During inspection, pay special attention to the air ducts, separation screens, and fans.
• Clean: Regularly cleaning the destoner can prevent cross-contamination of products and maintain the product's quality. Depending on the type of material processed and the frequency of use, the machine's cleaning cycle may vary.
• Lubrication: Regular lubrication of the moving parts of the stoner destoner can minimize friction and wear, extending the equipment's life. The lubrication intervals may vary depending on the frequency of use and the operating environment.

Scenarios of stoner destoners

• Grain processing plants

  Grain processing plants use stoners after the initial crude stone removal, which can help refine the product quality and further reduce the stone content in the final processed grains. By incorporating stoners, the processing plants enhance the quality, purity, and market competitiveness of the processed grains, thereby satisfying the demands of consumers and food standards.

• Food manufacturing and high-tech food processing factories

  Demonsters used different kinds of root crops in food factories, such as potatoes, carrots, and beets. The primary crops were transformed into snacks, desserts, or frozen products. The presence of destoners not only guarantees the food's quality and safety but also provides consumers with a more wholesome and satisfying eating experience.

• Agricultural product export companies

  Agricultural product export companies must adhere to strict international market standards to avoid agricultural products being rejected by foreign importers due to contamination with stones and other foreign materials. Including stoners can assist these businesses in meeting export requirements, thereby securing market access and enhancing international competitiveness.

• Organic food brands

  Organic food brands attach great importance to the quality and safety of their products, and stoners can help these brands remove impurities and stones, thereby improving the purity and quality of the grains.
