Henan Jinzen Machinery Co., Ltd., located in Zhengzhou City, Henan Province, successfully produced suction type pneumatic conveyor,port pneumatic grain unloader, mobile grain conveyor, diesel type pneumatic conveyor, grain airslide conveyor in 1990, and is a professional manufacturer of China's national pneumatic conveyor (grain suction air conveyor).Our grain conveyors are exported to 26 provinces, municipalities and autonomous regions across the country, and exported to Malaysia, South Korea, India, Vietnam, Hong Kong and other countries and regions, and have a high reputation among users. The grain pneumatic conveyor has developed into a series of products. Their specifications are QH-5, QH-10, QH-15, QH-20, QH-20C, QH-30C and other models. All models are powered by electric motors and adopt electric control boxes. Centralized control, suitable for 380 volts, 50 Hz AC power supply areas, among which the QH-20 model won the 1985 provincial quality product certificate, and the diesel type pneumatic conveyor are produced according to user needs.Our factory has cutting, stamping, finishing and other advanced process equipment and precision testing instruments, complete testing methods, and high-quality and reliable products. The developed QH series of replenishment, unloading, pneumatic conveyors move flexibly, and are quick and convenient to assemble. After a simple combination, they can be used for single suction, pressure delivery, or mixed suction and pressure transportation. You only need to arrange the delivery pipeline as required. It can transport granular materials such as wheat, corn, soybeans, barley malt, etc. horizontally, vertically, and inclinedly.It is especially suitable for replenishment, unloading, overturning, reverse gear of large grain depots, as well as mechanized operations in the production process of farms, grain processing, beer, and brewing industries. The newly developed QH series C-type pneumatic grain conveyor is equipped with an intermediate dust collector and a special suction nozzle for local deep grain suction, which can penetrate into the grain layer below 6 meters to take local grain, especially suitable for square silos, embankment silos, etc. due to poor ventilation The local high temperature caused by the extraction of grain.
