About Us
Company History
Stengel Grain Processing, also known as Stengel Seed & Grain, is a fifth-generation family-owned business led by Doug Stengel. The company specializes in toll cleaning a wide variety of grains, seeds, and edible beans for the organic food industry.
With five cleaning lines and two advanced color sorters, Stengel Grain Processing can handle multiple products simultaneously, allowing the company to efficiently meet diverse customer requirements while maintaining high standards of quality and service.
The Stengel family's grain-cleaning tradition began generations ago when Doug's father and grandfather cleaned seed for their own farming operations. While the fundamental principles of grain cleaning have remained largely unchanged over the past century, the equipment and technology used have evolved significantly to improve efficiency, accuracy, and product quality.
Today's food industry demands exceptional levels of purity, often requiring highly specialized processing equipment. To meet these exacting standards, Stengel Grain Processing frequently designs and builds custom machinery tailored to the specific needs of its customers. This commitment to innovation and problem-solving enables the company to consistently deliver the product purity and performance that toll-cleaning customers require.
