Special production line for pesticide dry suspension concentrate (DF preparation)

Heroin drying technician has developed a special production line of pesticide dry suspending agent (DF preparation) on the basis of F-YPL anti sticking spray drying small granule preparation line, which is another typical representative of Ho Mai's innovation ability. 1. Dry suspension concentrate water dispersible granule, also known as dry suspension agent, is a new pesticide formulation and preparation processing technology developed in 1980s. It is a solid preparation that can be dispersed in water.

1. Pesticide DF dry suspension concentrate

Also known as water dispersible granule, it is a new type of pesticide which can be dispersed in water. It is considered to be an ideal pesticide formulation with all the advantages of granule and high dispersibility of SC, which will be one of the important development trends of pesticide formulation processing.

2. The characteristics of DF dry suspension concentrate are as follows

  1. The dry suspension concentrate does not need solvent, dissolves in water and disintegrates rapidly. It has good dispersibility and suspension property and high suspension rate.

  2. The medicine liquid particles are very fine and can be evenly attached to the surface of crops, with strong adhesion and resistance to rain erosion.

  3. No dust, good fluidity, saving packaging materials, convenient transportation and storage;

  4. Large scale continuous and green production with good production environment;

  5. The reasonable distribution of the particle size of the solution can not only ensure the quick effect and sustained effect of the pesticide, but also ensure that the pesticide can fully contact with the surface of the crop, so as to improve the efficacy.

3. Application range of dry suspension agent

At present, dry suspension concentrate has been widely used in pesticide, medicine and veterinary medicine.

4, continuous anti sticking wall spray drying small granule preparation line.

Process Description: it is composed of feeding device, hot air inlet device, cold air, main tower, receiving device, secondary fluidized bed and tail gas system.

The feeding device is generally composed of feed pool, filter, feed pump, stabilizer, feed valve and atomizer in turn. Its function is to atomize the feed liquid into the drying tower by atomizer after treatment.

The hot air inlet device is generally composed of hot air blower, high temperature heat source, inlet air temperature measurement, air inlet pipe and hot air distributor 6. Its function is to provide hot process air for drying into the drying tower to form hot air in the tower.

In the drying tower, the hot process air contacts with the atomized droplet, which acts as instantaneous drying.

The function of the two-stage fluidized bed is to dry the semi-finished products to the appropriate moisture at low temperature, and prevent the finished products from deteriorating at high temperature, which will affect the disintegration performance.

Cold air is generally composed of air blower, heater and air supply pipe, and its function is to lower the temperature of finished particles.

The tail gas system is generally composed of induced draft fan, exhaust pipe and tail gas treatment device. Its function is to avoid environmental pollution caused by bad smell of tail gas and trace dust. In the implementation example, the scheme of water dust removal can be adopted.

The production line has the following outstanding effects: the diameter of finished products is about 80-120 mesh hollow particles, which greatly reduces or avoids the non dry wall sticking of materials, electrostatic wall sticking of dust and thermal viscosity, improves the final production efficiency, single equipment output, continuous production time, safety and product quality, and reduces the overall energy consumption. The above processes can be designed to increase or decrease.

Our company, combined with many years of production experience, has concentrated on designing a new spray drying machine for pesticide DF dry suspending agent, which can complete the drying and granulation process at the same time. According to the requirements of the process, we can adjust the pressure, flow rate and the size of the orifice of the material pump, and obtain the required spherical particles with a large proportion.
