Our Machines


The friction disk extruder produces both Baked and Fry-Type twists using degermed corn grits, polished rice grits, lentils, peas etc.


The friction disk extruder is designed for high productivity, at both high and low throughput, which is achieved by integrating a sophisticated mechanical design with advanced control systems.


The cooking extruder is designed to produce up to 2400 kg per hour of cooked, expanded or formed pellets or collets for the production of pet food, stock feed, fish food or human food such as snacks and breakfast cereals.


The grain extruder is designed to produce between 80 and 200 kg per hour of raw expanded collets from a variety of grains such as rice, maize, mungbean and soybean.


The MoistScan MA-700 In-Pipe Microwave Moisture Sensor is ideal for monitoring moisture at various points along the processing chain.


KoEx manufactures a range of preconditioning cylinders for the preparation of uniformly mixed and hydrated powders for supply of extrusion cooking systems.
