Multi-Crop Ewing Grinder

Bountifield’s Ewing Multi-Crop Grinder is a multi-functional burr mill technology that can be used to produce a variety of value-added products like flour from grain or a creamy paste from roasted nuts. The multi-crop grinder is designed to be either hand-operated or motorized, making it compatible to the needs and resources of the end-user.

Technologies such as this opens new opportunities to pursue microenterprises. Alternative enterprise opportunities are incredibly valuable, allowing families to gain an income, empowering women to participate in economic life, and contributing to food security by increasing local food production. Our grinders help to:

  • Reduce the drudgery and time associated with traditional processing methods
  • Produce high-quality, value-added products
  • Cultivates opportunities for microenterprises
  • Lead to richer participation of women in the economic sphere
  • Strengthen food security through increased incomes and production

Our high-quality grinders are equipped with heat-treated burrs that never require sharpening and withstand long-term wear, making the need for replacements a rarity. They were designed to be assembled in minutes and can be cleaned as equally fast. Bountifield's multi-crop grinder helps communities improve nutrition by producing a variety of high-nutrient, value-added products, ranging from cocoa butter to maize and millet blended flours that improves the quality of diets.

Pearl Millet Thresher

Pearl millet is a nutritious cereal grain that grows in some of Africa's most famine-prone regions, producing reliable yields in dry, hot climates with poor soil quality. Though pearl millet is a major source of nutrition for the rural poor, its production and market potential are limited by inefficient and labor-intensive traditional processing methods.

Our thresher was invented to help smallholder farmers—women in particular—increase their yields of pearl millet grain while minimizing their drudgery. The hand-operated tool is rugged, simple, and produces kilos of clean, high-quality grain in minutes.

Bountifield’s thresher strips, threshes, and winnows grain in a process that:

  • Produces high-quality, clean grain free of dirt and debris
  • Produces grain much faster than traditional methods
  • Reduces food waste that occurs with traditional processing methods

Manufacturing: We are working with a manufacturer in Senegal to establish local production of high-quality threshers. In addition, local artisans across Senegal are being trained to provide troubleshooting support to clients in their regions.

Distribution: We are working with Senegalese farmers' networks and extension agencies to introduce the thresher and train farmers to use the technologies and generate income through the sale of high-quality grain and seed.

The thresher can be owned collectively by cooperatives, by individual households, or by businesses, who can process their grain at their convenience and use it for local consumption, store it, or sell it at local markets.

Peanut Processing Tools

Our suite of mechanized groundnut processing technologies are designed to increase small farmers’ productivity, improve the quality of peanut harvests, and reduce labor.

Using the tools, a farmer can harvest, strip, and shell a hectare of groundnuts in just 12 days — more than 8 times faster than traditional labor methods! The tools were designed to be rugged, affordable, and easy to operate.

The suite of devices harvest peanuts, strip pods from the roots, and shell whole nuts.

The lifter, stripper, and sheller were designed by a team of engineers and researchers from Bountifield|CTI and ICRISAT, in collaboration with smallholders from Malawi and Tanzania. The tools were extensively field-tested throughout the peanut producing belt of Malawi from 2011 to 2014 and modified based on feedback from farmers.

With support from the McKnight Foundation, Bountifield is working with local manufacturers to produce the tools in Malawi. We are piloting the technologies with farmer organizations across Malawi, including NASFAM, the largest smallholder farmer group in the country. Farmer groups like NASFAM give smallholder farmers access to resources like new technologies, training, and good seed. With this partnership, farmer organizations can now offer Bountifield's peanut tools to their members, giving farmers access to the support necessary to reap the full benefits of their labor.

Peanut Lifter

Farmers traditionally harvest peanuts by digging with a hand-hoe and manually lifting the plants from the ground. Bountifield’s lifter consists of a frame with a blade that sinks below the ground’s surface to cut the roots of the groundnut vines, loosen the soil as it is pulled forward by an oxen or small tractor. On the back of the blade, steel rods shake off excess soil and lift the plant away from the ground. The lifter can be adjusted to accommodate the heights of different users.

Peanut Stripper

After harvest, farmers traditionally spend several days tediously hand plucking groundnut pods from the plants one by one. Bountifield’s stripper is comprised of an A-shaped frame covered with a woven metal screen, similar to chain link fencing.

To operate the stripper, the user simply drags a groundnut plant across screen, putting pressure on the pods with one hand which allows the metal to snag the groundnut pods away from the plant and drops through the screen to the ground or over a tarp.

Peanut Sheller

Typically, groundnuts are shelled by hand, most often by women. Farmers commonly wet their pods to soften their shells, causing considerable risk of contamination from bacteria, fungus, and aflatoxin. Bountifield’s sheller is a hand-operated device that scrapes groundnut pods between a rotating disk and stationary steel rods. The gap between the disk and rods narrows as the nuts fall down the sheller, and the nuts are easily shelled with minimal broken or split kernels.
