Maize gravity destoner

Types of maize gravity destoners

The maize gravity destoner sorts food grains based on their consistency. It has a stone trap that secures stones and other debris. When maize grain enters the funnel, it spreads through the tray, where an airflow system pushes stones downward. Compressed air, mechanical vibrating trays, and slanting trays are the major types of maize gravity destoners used in the corn flour industry.

• Air compressed maize gravity destoner:

  This air compressed maize destoner operates with compressed air working against the tray. It pushes the lighter materials above the tray and supports the stones to fall in the trap beneath the tray. The main advantage of the compressed air destoner is that the air supply can be adjusted. This permits the handling of varying product qualities and volumes, ensuring thorough separation.

• Mechanical vibrating tray maize destoner:

  A mechanical vibrating tray maize gravity destoner works by vibrating the tray. The stones and heavier materials quickly migrate to the tray's bottom and drop into the stone chamber. While the light materials flow to the side of the tray, this mechanical destoner gives a constant separation process. It is easy to maintain and operates well in dry seasons.

• Slanting tray maize gravity destoner:

  In a slanting tray maize gravity destoner, the tray is at a slant position. It separates light and heavy materials due to the slant position and air flow pushing upwards. The flow of air pushes materials upward with the help of a slanting tray. This type of destoner comes with a tray of different sizes to handle many quantities. It is also efficient in power use.

Specifications and maintenance of maize gravity destoners

Specifications

• Feeding volume: There are some common feeding volumes for the maize stone removers, such as 2ton/h, 5ton/h, and 25ton/h. Business buyers could adjust the volumes by changing the machines' sizes and parameters to meet distinct demands.
• Separation layers: Different maize gravity destoners offer various separation layers. The common ones are 3 and 5 layers. Some models with 5 separation layers have the further separation ability. They could separate more grains, such as stones, wheat, rice, and salt, in addition to maize, legumes, and beans.
• Airflow: The maize gravity destoner must be compacted with the maize mill blower or another air blower to separate the stones. The air flow from these blowers typically ranges from 0.5t/h to 3t/h.
• Power: The power of maize gravity destoners usually ranges from 1 to 10 horsepower (HP), depending on the machine's model and specifications. A 1-HP machine, for example, can effectively eliminate stones and impurities from a small to a medium-sized maize processing facility. A 5-HP machine would be a better option for domestic or commercial use with a higher capacity.
• Wattage: It is similar to the power of the maize destoners. For a typical maize stone remover, the wattage ranges from 1 to 7.5. The value is 1,000-7,500.
• Dimension: The dimension of the maize gravity destoner varies according to the model and specifications. A common commercial machine is 1,800 mm in length, 700 mm in width, and 2,200 mm in height.
• Weight: The weight of the maize gravity destoner is between 350 kg and 2,000 kg.

Maintenance

• Clean: The maize gravity destoner should be cleaned thoroughly, including the frame, screen, and air duct, at least once a week or more frequently as needed. It prevents dirt, maize flour, and other impurities from accumulating to ensure the air flow and separation effect.
• Inspection: Regular inspections should be conducted to check whether key parts, such as screens, blades, and air ducts, are damaged or loose. Any issues should be addressed promptly to avoid hindering maize gravity destoners' efficacy and safety.
• Lubrication: The vibrating part and the bearings of the maize gravity destoner should be regularly lubricated to ensure smooth operation. Especially for the rotating bearings, it is better to apply proper lubricant in advance.
• Tension adjustment: The maintenance personnel need to adjust the tension of the drive belt and the screens regularly to ensure their appropriate tightness. The frequent adjustment may help avoid slippage, abrasion, and noise.
• Replace the screen: The operating capacities of maize gravity destoners depend highly on different screens' separation abilities. With time going by, the screens may get enormous damage or wear out. Therefore, the old ones should be replaced with new ones to ensure the machine's functioning and separation efficacy.
• Remove the blockage: The cyclone site of the destoner should be inspected periodically to remove the blockages caused by debris and dust to waste the air flow and improve separation efficiency.

Usage scenarios of maize gravity destoners

Maine gravity destoners are widespread in many industries that deal with various kinds of grains. The food processing industry uses the maize gravity destoner to separate maize from stones and other undesired materials. This guarantees the safety of the consumers and prevents any form of litigation from the use of faulty products.

Breweries are one of the heaviest users of the maize gravity destoner. This is because the primary product they use in making beer is maize. The device assists them in removing undesirable materials such as stones, husks, and other light impurities. The brewery then gets clean maize that can be processed into beer.

The animal feed manufacturers utilize the maize gravity destoner to create an animal product free from impurities that can harm the animals. Livestock and poultry require spotless grains in order to achieve maximum health and productivity. Consequently, animal feed manufacturers use the maize gravity destoner to provide a product free of impurities.

Restaurants and cafeteria kitchens also have the maize gravity destoner as part of their kitchen equipment. Corn is a staple food and ingredient in many cuisines. The device allows these kitchens to prepare and serve high-quality, impurity-free food to their customers.

How to Choose Maize Gravity Destoners

When choosing a gravity destoner machine, there are a few key factors to consider. These include the quality of the stones being separated, the capacity and power of the power source, the working principle of the machine, the design and features, the installation requirements, the maintenance and repair needs, and any safety considerations.

Before buying a maize gravity destoner, it is important to evaluate the quality of the stones to be separated. Different types of gravity destoner machines are designed to separate different types of stones. For example, some machines are specifically designed to separate rice stones, while others are designed to separate wheat stones. Knowing the type of stones that need to be separated will help in selecting the right machine.

The capacity and power of the gravity destoner machine will also be an important thing to consider. The machine's capacity should be high enough to handle the volume of feed in a business setting. Additionally, the power source, whether electric or manual, should be convenient for the premises where it will be used.

It is also important to consider the working principle of the gravity maize destoner machine. These machines typically work by vibration and air flow. The vibration separates the stones and heavier impurities from the grains, while the air flow moves the lighter materials. Understanding this working principle will help in selecting a machine that works effectively.

The design and features of the gravity destoner machine should also be considered. Different machines have different designs, such as cross flow or counter flow. Some machines have multiple separation decks for improved efficiency. The features, such as digital controls or dust collection systems, should also be considered as they may affect the overall performance of the machine.

Before purchasing a maize gravity destoner, it is important to clarify the installation requirements with the supplier. This includes the space needed, the power connections, and any additional accessories required to set up the machine properly.
