We are always designing and manufacturing vegetable oil pre-treatment and pressing line based on characteristics of different vegetable oils as well as customers` requirements. In this way, we are able to ensure optimum conditions of the oil obtained by enhancing oil yield, improving protein content and oil quality.
Process Workflow
Raw Material Unloading and Warehousing → Cleaning, Grading, Stone Removing, Weighing → Drying, Crushing and Seed Dehulling → Flaking → Extruding → Cooling
(1) Raw Material Unloading and Warehousing
Major Devices: automatic unloading machine, cleaning and classifying screen, elevator for delivering goods into silos, horizontal conveyor and conveyor for taking goods out of silos
(2) Cleaning, grading, stone removing, Weighing
Major Devices: flat classifying screen, specific-gravity stoner, online meter and magnetic separator for iron removal
(3) Drying, crushing and seed dehulling
Major Devices: magnetic separator for iron removal, crusher (huller) and kernel and husk separator
Features of kernel and husk separator
Inverter-driven feeding device is able to ensure even distribution of materials. An air-lock valve is installed at the feeder to guarantee normal feeding. Generally, soybeans or other seeds will be thrown against each other from various directions, which results in intense collision. Hence, hulling efficiency is highly improved. Furthermore, wind and mixture of kernel and husk run towards each other to ensure full contact, thus significantly improving husk removal efficiency. A vision glass is also equipped on the separator for real time observation of hulling and separating process.
