4 Ton Roaster

The 4 Ton Roaster by A.N. Martin Systems is a fully automated, electric-powered roasting system capable of processing up to 8,000 lbs. of soybeans per day. Designed for continuous 24/7 operation, the roaster uses heated oil inside a double-wall pipe to cook soybeans at 375°F for one hour. As the oil warms, it naturally circulates due to the unit’s incline, maintaining consistent roasting temperatures. After roasting, the beans move into a steeping chamber, where they are gently cooked for another 30 minutes, exiting at approximately 250°F for an even, fully-cooked result.

Once roasted, the beans are cooled to ambient temperature in a cooling hopper with an axial fan before being ground by an 18” hammermill. The hammermill can process up to 5 tons per hour and features reversible hammers, a quick-change screen, and an adjustable outlet angle for a consistent grind, ideal for dairy feeding.

The entire 4 Ton Roaster system is controlled by a touchscreen panel with built-in automation, safety sensors, timers, and over-temp shutoffs. The SoyRoaster is pre-wired and installed in a shipping container, making installation simple—just connect power, a fill auger, and your discharge piping. For farms looking for more flexibility, a DIY option is also available. With the DIY kit, components are shipped loose for farmers to install in their own building or container, offering the same performance with added customization.
