Dry Flowables
2023/03/08
Dry-Flowables (DF) is a solid formulation type with very different production process from traditional Water Dispersible Granules (WG). Traditional WG is manufactured mainly by extrusion granulation or fluidized-bed granulation after pulverized in jet mill, which are regarded as dry processing technology. However, DF is produced by wet processing technology with the following steps: First, a fine suspension concentrate (SC) is obtained through sand grinder and high-speed shearing process. Then, SC liquid is pumped up and sprayed dry inside a high tower with pressure. Finally, DF granules are formed after rapid dehydration and consolidation.
The advantages of Dry-Flowables (DF)
- 1)The average particle size of DF can reach less than 5 um (micron) after dilution, which is much smaller than traditional WG with particle size of 10-40 um. Higher fineness improves suspensibility, dispersibility and efficacy of the product.
- 2)DF granules can completely disintegrate in water within 6 seconds, forming very fine and stable suspension concentrate (SC), which will not create precipitate or clog the sprayer’s nozzle.
- 3)The extreme fine droplets can spread on the surface of crops uniformly, to form a high-densed protective film and to strengthen the extensibility, adhesivity and rain-resistance. Meanwhile, it can avoid the phytotoxicity caused by excessive condensed products in particular parts of the leaves.
- 4)DF is much easier to use and store with higher stability and longer shelf life compared with SC formulation.
- 5)As Eco-friendly formulation, DF reduces the use of organic solvents. No dust is created in production or application process, providing high safety to the operators, users and the environment.
