Pneumatic vacuum conveying systems utilise the principle of vacuum negative pressure (generated by a vacuum pump, which draws material through a suction pipe and then discharges it into the target equipment via vacuum release) to achieve sealed material conveyance. These systems offer dust-free cleanliness, high automation levels, and compatibility with various materials (powders, granules, small blocks), among other features. They are primarily applied in the following industries:
Food industry：
Powdered materials: flour, milk powder, coffee powder, spice powders (such as cumin powder, chilli powder), artificial sweetener powders, etc. Vacuum conveying prevents dust from spreading and contaminating the workshop, while also preventing material moisture absorption (sealed conveying reduces contact with air).
Granular materials: grain particles (such as millet, oats), nut fragments, candy particles, etc. This avoids particle breakage or contamination from impurities caused by manual handling.
