Wdg Pesticide Water Dispersion Granule Production Line

Overview
Granules (Granule or GR) are referred to as granules, and granular preparations processed by additives such as original drugs and carriers. The early field experiment of granules began in 1946, and was widely used in the United States in the early 1950s. In the early 1960s, Japan began to use it in large quantities. Due to the development of environmental science in the late 1960s, pesticide granules have been widely used throughout the world in order to avoid contamination of the environment and crops by particle drift during pesticide powder spreading. The development of granules in China was mainly in the late 1970s. In 1989, the Ministry of Chemical Industry statistic granules accounted for about 7% of the total pesticide preparation.

Granules can be a commonly used pesticide because of its unparalleled characteristics:
1 It has directionality when applied, so that the spreading agent can fully reach the target organism and be safe for beneficial organisms such as natural enemies;
2 the drug particles are not attached to the stems and leaves of the plant, avoiding direct contact with phytotoxicity;
3 There is no dust flying when applying the medicine, and it does not pollute the environment;
4 During the application process, the operator's body adhesion or inhalation dose can be reduced to avoid poisoning accidents;
5 to make high-toxic pesticides low-toxic, to avoid poisoning of humans and animals;
6 can control the release rate of the active ingredients in the granules, and extend the duration;
7 easy to use, high efficiency.

In summary, the pesticide water dispersible granules (WDG). The International Federation of Pesticide Industry Associations (GIFAR) defines it as: granules used after disintegration and dispersion in water. The water-dispersible granule is mainly composed of an active ingredient of a pesticide, a dispersing agent, a wetting agent, a binder, a disintegrating agent and a filler, and has a particle diameter of 200 μm -5 mm, and can rapidly disintegrate and disperse after entering water to form a high suspension dispersion system.
Jiangsu Pioneer Drying Engineering Co., Ltd. based on ^ process technology and rich experience in production, no improvement and innovation, has designed a new WDG pesticide water dispersible granules special production line, fully meet the market for pesticides without dust, easy to collapse Resolving, easy to transport and other requirements, has become a well-known domestic production line of WDG production lines, and has dozens of engineering cases for users to visit and certification.
Our company can carry out engineering design according to the actual requirements of users. At present, the output of single production line is 100kg/h, 200kg/h, 300kg/h, 500kg/h, 800kg/h, etc.
Equipment characteristics of WDG pesticide water dispersible granule production line
1. The WDG pesticide water dispersible granule production line adopts the form of integrated crushing, mixing, granulating, drying, cooling, sieving and packing sections. It has the functions of clear, organic combination and coordinated operation to achieve the process flow.
2. The core part of the production line: the drying system. Adopting the method of sectional heating, the pre-drying section adopts the high-pressure low-air volume fan to make the wet WDG particles completely fluidized; the drying section adopts the low-pressure and high-volume fan, taking away more water per unit time and drying evenly; The high air volume fan can quickly remove heat and reduce the temperature of the product, which not only meets the requirements of moisture control, but also facilitates the subsequent packaging process.
3. Dry medium circulation system: The blower, heater and air inlet duct are made of stainless steel to avoid the possibility that the product will be contaminated by unclean wind.
4. The quick-opening structure between the upper and lower beds of the drying host changes the traditional structure by bolts and connects the form, which greatly facilitates the thorough cleaning of the system.
5. The hole type of the paving bed plate adopts a combined structure, and the front section adopts a tongue-shaped hole, so that the material can smoothly move forward without causing leakage; the middle end uses a straight hole, and the hot air has a higher penetration rate and is dry. The heat exchange of the process is more complete.
6. The inside of the lower bed body is made of stainless steel full-welding, which avoids the sewage entering the insulation layer when washing, thus affecting the product quality, and also has a cleaning port to facilitate cleaning equipment.



WDG pesticide water dispersion granule production line process and production equipment:
Production process 1: Weighing ingredients → mixing (ZGH vertical high-speed mixer) → granulation (ZL rotary granulator) → drying (XF boiling dryer) → screening (ZS, FS type oscillating sieve) →Feeding (ZKS vacuum feeder)→Packaging
Production process 2: Weighing ingredients → One-step method (XLB type cyclone granulation coating machine) → Screening (ZS type oscillating screen) → Feeding (ZKS vacuum feeding machine) → Packaging
