Applications of CFAM extrusion technology
CFAM’s extrusion systems find applications in various industries, where they add value to raw materials and facilitate the production of high-quality products. These applications span the following:

Pet food
The production of pet food through CFAM systems allows for precise customisation to include essential nutrients, vitamins, and minerals, catering to diverse dietary needs. The technology ensures consistent texture, shape, and size, delivering products suitable for all market segments, from economy to premium-grade options.

Aqua feeds
CFAM extrusion systems enable sustainable and efficient aqua feed production. The feeds are designed to reduce waste, with floating or slow-sinking options that minimise environmental impact. High digestibility ensures optimal nutrient absorption for aquatic species, supporting healthier growth. Furthermore, formulations can be tailored to meet the specific dietary needs of various aquatic organisms, including fish and shrimp.

Breakfast cereals
Breakfast cereals produced with CFAM technology meet consumer demands for convenience and nutrition. The equipment allows for the creation of diverse cereal products, including flakes, puffs, and clusters, with customisable shapes, flavours, and textures. The inclusion of whole grains and other health-focused ingredients ensures alignment with modern dietary trends.

Snack foods
CFAM extrusion technology supports the production of innovative snack foods with creative shapes and appealing flavours. These systems cater to the growing market for health-conscious snacks by enabling the manufacture of high-protein, low-fat options. The efficient production processes also ensure cost-effective operations, reducing waste and enhancing profitability.

Instant porridges
Instant porridges created using CFAM systems offer rapid preparation, enhanced nutritional value, and versatility in formulation. These porridges can be enriched with vitamins, minerals, and proteins, providing balanced nutrition for various demographics. CFAM’s technology accommodates diverse raw materials such as maize, sorghum, rice, and millet, allowing the production of multi-grain porridges.

Multi-grain porridges combine the nutritional benefits of different grains, offering improved fibre content, essential amino acids, and a range of vitamins and minerals. The inclusion of fortification further boosts the nutritional profile, addressing micronutrient deficiencies in target populations. These products can be tailored to meet the dietary needs of specific groups, such as infants, young children, athletes, or individuals with dietary restrictions.

CFAM’s systems also support the use of locally sourced raw materials, fostering economic growth in communities while providing cost-effective production solutions. By enabling customisation of formulations to align with cultural preferences and dietary guidelines, CFAM’s instant porridges address both nutritional and market demands.

Wholegrain products
CFAM’s technology plays a pivotal role in integrating whole grains into snacks, breakfast cereals, and instant porridges. Whole grains provide a range of economic and health benefits. Economically, using locally sourced whole grains reduces costs associated with imported refined grains and adds value to premium market segments. From a health perspective, whole grains are rich in fibre, vitamins, and minerals, supporting cardiovascular health, improving digestion, and aiding weight management. These benefits make wholegrain products appealing to a broad consumer base, including health-conscious individuals.

Incorporating whole grains into snacks and breakfast cereals offers a dual advantage of financial savings and enhanced health benefits. From a financial perspective, using whole grains can lead to cost efficiency. Whole grains, compared to refined grains, often have lower production costs due to fewer processing steps required to remove their nutritious components. This cost-effectiveness can positively impact manufacturers’ bottom lines while delivering better value to consumers.

From a health standpoint, the benefits of using whole grains are substantial. Whole grains are rich in dietary fibre, which aids digestion, promotes satiety, and helps manage weight. The complex carbohydrates found in whole grains release energy gradually, providing sustained fuel and preventing sharp spikes in blood sugar levels. Additionally, whole grains are abundant in vitamins (like B vitamins) and minerals (such as magnesium, iron, and zinc), supporting various bodily functions and overall well-being.

The high fibre content of whole grains contributes to heart health by lowering cholesterol levels and reducing the risk of cardiovascular diseases. Moreover, the antioxidants present in whole grains combat oxidative stress, potentially lowering the risk of chronic illnesses like diabetes, certain cancers, and inflammation-related conditions.

Choosing whole grains for snacks and breakfast cereals therefore translates to financial savings due to reduced processing costs. Simultaneously, these products offer health benefits through their rich fibre, nutrient, and antioxidant content, promoting digestive health, balanced energy release, and contributing to the prevention of various chronic diseases. This dual advantage appeals to both manufacturers and health-conscious consumers, aligning profitability with public well-being.

CFAM Technologies originated as a research project within the School of Mechanical Engineering at North-West University (NWU) in South Africa. The initial focus was on developing and optimising twin-screw extrusion technology for various applications, including food processing, feed production, and industrial uses. The success of the research project and the potential commercial applications of the technology led to the establishment of CFAM Technologies in 2007. The company was founded to commercialise the twin-screw extrusion technology developed at NWU, providing high-quality, locally manufactured extrusion systems tailored to the needs of the African market and beyond. Over the years, CFAM Technologies has grown significantly, expanding its product range and customer base. The company has become known for its innovation, quality, and commitment to customer service. We have also contributed to food security and economic development in the regions we serve by providing technology that enables local production of food and other products.
