About mist duster

Types of mist dusters

As agriculture plays an important role in supporting the economic development of many sectors and industries, tools like the mist duster have emerged with great importance.

The basis of its operation is to disperse pesticide fog quickly and massively around the field. While the design may vary, all models closely adhere to the same functional concept.

Generally speaking, the mist dusters are classified in two main ways: the sprayers and the types of sprays they can do. The first refers to the method of how pesticides are applied, and the second refers to the sizes of fog particles.

  • According to the application method:
  • Usually, mist dusters are based on the atomization of pesticides and the movement of air currents; they can be divided into two categories: air compression mist dusters and gas-powered mist dusters.

    Air compressor mist dusters refer to the machines that use compressed air to atomize and spray pesticides. These may utilize an air compressor as the power source for the spray. The process starts when the compressed air pushes the liquid agriculture chemical through an atomizing nozzle. The liquid is then transformed into fine mist, which is subsequently sprayed onto the target area. Farmers can use this type of mist duster to cover a large area of farmland or eliminate pests and diseases at a fast pace.

    Gas-powered mist dusters, on the other hand, refer to those using gas or gasoline as a power source. The gas engine creates a high-speed airflow that atomizes and sprays pesticide mist. This type generally features portable and versatile fumigation solutions for outdoor and open areas.

  • According to the size of fog particles:
  • Another basis mist dusters can be separated is into fine mist dusters and coarse mist dusters. The former refers to the fine mist (small particles around 10-100 microns) produced by the machine. They are also popularly known as fine mist sprayers. Their precision spray can quickly permeate the target object, which is widely used in pest control, forestry management, and disease prevention.

    On the other hand, coarse mist dusters produce larger droplets (larger than 150 microns). They are also known as coarse spray mist dusters. The big spray is used for heavy coverage, reducing product loss to evaporation or vaporization. They are suitable options for agricultural fields with high water demand or in windy environments.

Specifications and maintenance of mist dusters

The specifications of mist dusters will differ based on the models and types available. Some main specs are outlined here.

  • Capacity: The capacity of mist dusters is usually measured in liters or ounces. Agricultural mist dusters used for farming, pest control, or forestry will have a typical range of 10 to 25 liters for the tank capacities. Fruit farms, for example, need a 20-liter mist duster spray machine model because the coverage area is large, and they need to spend more time spraying.
  • Power: The power output of mist dusters is generally measured in watts or horsepower. Agricultural dusters, for example, have a motor power ranging from 2-5 hp. The battery-powered dusters will be in the range of 30,000-120,000 milliwatts.
  • Range: The effective spraying range will vary based on the type and model of the mist duster. Spray distances can range from around 10 meters (32 feet) up to 30 meters or more.
  • droplet size: Depending on the manufacturer and model, the mist duster's droplet size can vary. The particles may range from coarse droplets(0.05mm to 0.5 mm) to ultra-fine droplets (less than 0.05mm). Some models can even produce mist particles in the normal range of 90 to 100 microns.
  • spray pressure: The spray pressure in mist dusters can vary between low to high. Some models have a low to high-pressure setting, and the pressure can vary/model from 0.5 to 5 bars.

Maintenance

For long-term use and optimal performance, it is essential to clean and maintain the pesticide mist duster, pest control mist sprayer, or any other kind regularly.

As the residue accumulates, the performance of the device declines. Problems such as blockage, corrosion, damage, and leaks occur. Cleaning the tanks and equipment helps remove the residue. Regular flushing and rinsing of the tanks or containers is necessary, particularly for corrosive chemicals. The application in the farmland of farm equipment also requires cleaning of water only.

In the lengthy run, the dust sprayer machine will function better, and spare parts will be less needed if the equipment is cleaned. This also helps avoid cross-contamination of farms or pest areas. Spraying with clean water at the end of the use of the product can reduce the need for harsh chemicals and manual cleaning. A simple approach is to flush the equipment with clean water, which will eliminate the need for extensive chemical use and manual interventions.

For comprehensive and thorough cleaning, the following steps are suggested:

  • Cleaning the outside: Use a soft cloth or sponge to wipe off the external surfaces of the tank, nozzle, and other parts. This removes any residual liquid or dirt. Mild detergents can be used to clean sponges or cloths to keep the equipment clean. After wiping, make sure the residue is removed entirely.
  • Cleaning the tank: Rinse the inner walls of the tank thoroughly with clean water while wiping them. Move the sprayer around to ensure every corner is accessible. Clean the water until there is no residual liquid dyed water.
  • Cleaning of filters: Often sprayers are fitted with filters that prevent particles from clogging the nozzle and ensure a steady flow of liquid. They need to be cleaned periodically as pesticide residue and other liquids can build up.

Uses of a Mist Duster

The mist duster has widespread uses across various industries and agricultural sectors. Here are some common use scenarios for the mist duster.

  • Pesticide Spray

  • The primary use of mist dusters is to apply pesticides in a wide area. With its atomization capability, mist dusters penetrate deep into crops, giving thorough coverage to plants where insects and pests hide.

  • Public Health Vector Control

  • Insecticide-treated mist duster machines control disease-transmitting insects like mosquitoes, flies and proboscis insects. They are used in fumigation exercises to reduce the population of these disease-causing insects around areas where people reside.

  • Forestry Management

  • Mist dusters are used in the forestry industry to apply herbicides and pesticides. They helpprotect tree vegetation from damaging bugs and unwanted plants, which makes forest management and tree conservation easier.

  • Livestock Protection

  • On farms that rear animals, mist dusters can be used to spray insecticides directly on the livestock to protect them from skin parasites like lice and ticks. Also, the livestock are protected from disease-transmitting insects such as mosquitoes and biting flies that can impact their health and productivity.

  • Structural Pest Control

  • Insecticide mist dusters can be used to control pests that damage facilities, structures, and belongings. Common ones are cockroaches, bed bugs, termites, and ants. With their precise targeting and low-volume applications, mist dusters can effectively treat infested areas while reducing the insecticide used in places like warehouses, hotels, and restaurants.

  • Fumigation

  • When carrying out fumigations in enclosed spaces or greenhouses, the correct-use instruction mist duster can apply insecticide gas to eliminate pests within these protected environments. It is also used in the shipping industry to eliminate pests in cargo holds and containers.

How to choose mist dusters
