Flat Fan Nozzles in Agriculture: Precision Spraying Solutions

In modern agriculture, precision spraying is crucial for increasing crop yields, reducing costs, and protecting the environment. Traditional spraying methods are prone to uneven coverage and wasted pesticides and fertilizers, impacting crop growth and production efficiency.

Flat fan nozzles deliver uniform spray, controllable spray angles, and optimized droplet distribution, enabling more efficient spraying of pesticides, fertilizers, and nutrients. Whether used for field crops, orchards, or greenhouse vegetables, these nozzles help farmers improve spraying precision, save costs, and support sustainable agriculture.

What is a flat fan nozzle?

Flat fan nozzles spray liquid into a uniform fan-shaped film, creating a uniform mist streak of fixed width along the spray direction. Design parameters include:

• Spray angle: Common options include 40°, 65°, 80°, and 110°. Narrow angles are suitable for high-pressure, concentrated spraying, while wide angles are suitable for large-area coverage.

• Flow rate range: Available from 0.1 L/min to 20 L/min, compatible with various pressure systems.

• Droplet diameter: Controlled by pressure and nozzle orifice design, typically ranges from 100–400 μm, ensuring a balanced coverage and absorption rate.

• Materials: Stainless steel, ceramic, and engineering plastics. Wear and corrosion resistance directly impact nozzle life and spray stability.

This structural advantage makes flat fan nozzles particularly suitable for agricultural applications requiring precise control of spray coverage, improved pesticide absorption, and reduced waste.

The application of flat fan nozzles in agriculture

Precision Pesticide Spraying

• Uniform Coverage: The fan-shaped spray strip ensures uniform coverage of crop leaves, minimizing missed or overlapping spraying.

• Reduced Chemical Use: Controlling droplet size and spray angle reduces pesticide loss and lowers pesticide costs per unit area.

• Crop Protection: For highly sensitive crops (such as grapes and strawberries), this feature minimizes spray damage and improves control efficiency.

Liquid Fertilizer and Nutrient Solution Spraying

• Optimizes nutrient absorption: Evenly distributes droplets, helping plants absorb nutrients evenly through their leaves and roots.

• Efficient: Avoids excessive fertilizer use, which can lead to soil salt accumulation and resource waste.

Weed and Pest Control

• Precise Targeting: Adjust the spray angle and pressure to focus spraying on affected areas, improving insecticide efficacy.

• Reduced Secondary Contamination: Reduce pesticide drift to non-target areas, protecting the surrounding environment.

Cooling and Greenhouse Environment Conditioning

In greenhouses or orchards, flat fan nozzles can be used for localized cooling or foliar moisturizing, improving crop growth conditions.

Flat fan nozzle FAQ

1. What crops are suitable for flat fan nozzles?

They are suitable for most crops with regular row spacing, including rice, wheat, corn, vegetables, and fruit trees. The spray angle and flow rate can be adjusted according to crop height and density, ensuring precise spraying.

2. What should I do if the nozzle becomes clogged?

Clogging is the most common problem, usually caused by impurities or sediment. It is recommended to use a filter to ensure fluid cleanliness and to regularly disassemble the nozzle for cleaning with clean water or a mild acid or base. For high-wear applications, ceramic nozzles can be used to extend their life.

3. What is the typical lifespan of a nozzle?

• Stainless steel nozzles: Typically 12–24 months

• Ceramic nozzles: Offer better wear resistance, up to 24–36 months

• Engineering plastic nozzles: Suitable for low-wear environments, but with a slightly shorter lifespan.

4. Can flat fan nozzles be used for drone spraying?

Yes, but be sure to match the spray angle and pressure to the drone's flight altitude, and choose wear-resistant materials to withstand frequent use.

5. How can I tell if a nozzle needs replacement?

• The spray angle is noticeably reduced or uneven.

• Differences in droplet diameter lead to reduced spraying effectiveness.

• Significant wear or corrosion on the material.
