How to Set Up a RUTF Production Plant? Equipment & Costs

For anyone looking at investing in or setting up a food manufacturing operation in this area, it's vital to understand the key stages involved in a RUTF production plant project. This guide walks you through the process of planning your plant, the equipment you'll need to process the RUTF, how you'll organise your production, and how you put together a production line to meet your own business needs.

1. Define Your RUTF Product and Production Requirements

The first step in selecting machinery is to work out what type of therapeutic food you intend to make.

 

RUTF is a high energy, nutrient dense food for the management of severe acute malnutrition. It's generally available as a ready to eat paste in individual sachets (no cooking, no water required).

According to the WHO guideline on the prevention and management of wasting and nutritional oedema, therapeutic food plays an important role in the dietary management of children with severe acute malnutrition. Manufacturers should ensure that product formulation and nutritional specifications are developed in accordance with applicable international guidelines and local regulatory requirements.  

Traditional formulations commonly contain ingredients such as:

• Peanut paste or other approved legume-based ingredients
• Milk powder or alternative protein sources
• Vegetable oil
• Sugar
• Vitamin and mineral premixes
• Other permitted ingredients depending on the formulation

 

The precise ingredient mix will of course depend on the target product specification and the relevant regulatory requirements.

 

At the planning stage, manufacturers should clarify several important factors:

• Product formulation: Work with experienced food formulation specialists to define the required nutritional profile, ingredient specification, texture and product characteristics.
• Production capacity: Work out the required daily or hourly output based on market demand, operating hours and future expansion plans.
• Packaging format: Will the finished product be packed in individual sachets, tubes or other approved packaging formats?
• Target market: Where are we going to manufacture and distribute the product? The regulatory regime and customer requirements may be very different in different countries.

 

These decisions will have a direct bearing on the equipment configuration and the total investment required.

2. Choose the Right RUTF Production Capacity

• Expected market demand and purchasing contracts
• Available raw material supply
• Planned daily production hours
• Number of production shifts
• Packaging speed and finished product storage capacity
• Potential expansion requirements

A properly configured RUTF production line should therefore be designed around the required finished product output rather than the capacity of a single machine.

3. Select the Essential RUTF Processing Equipment

Equipment selection has a direct bearing on how efficiently the raw materials are converted into a consistent finished product.

 

Although the exact configuration will vary depending on the formulation and the manufacturing process, a peanut based RUTF facility may consist of the following equipment sections.

 

Raw Material Cleaning and Preparation

 

The process starts with inspection and preparation of the incoming raw materials.

For the peanut based formulations, the cleaning of the equipment will remove stones, dust and the like prior to further processing. Magnetic separators and metal detectors can provide an extra layer of protection against the presence of metal.

Raw material preparation may also involve sorting and grading equipment (depending on the ingredients being used of course).

 

Peanut Roasting and Grinding

 

Peanuts generally need to be appropriately thermally treated prior to being made into paste.

 

An industrial peanut roasting machine provides the controlled heating as per the validated process. After roasting and appropriate cooling/handling the skins can be removed by a peeling machine if required.

The prepared peanuts are then fed into the peanut grinder.

The grinding system will reduce the particle size and produce a smooth peanut paste which is then suitable for formulation and mixing. The equipment selection will be based on required grinding fineness, temperature control, processing capacity and the required final texture.

 

Ingredient Mixing and Homogenization

 

This section combines the peanut paste with the other ingredients as per the approved formulation.

 

An industrial mixing machine will mix the ingredients through the product to give a uniform mixture. The system will be capable of handling oils, powders and micronutrient premixes depending on the formulation.

A homogeniser or fine grinding system may be incorporated to improve product uniformity and texture. The equipment should be selected on the basis of the required particle size, viscosity and product characteristics. These have to be validated by product testing rather than simply assumed from the equipment specification.

 

Filling and Packaging

 

Once the product has passed the requisite processing and quality checks it moves into the filling section.

 

A suitable automatic filling and sealing machine can dispense the pre-prepared paste into individual sachets with the correct filling quantities.

 

When selecting packaging equipment, manufacturers should evaluate:

• Sachet dimensions and packaging material compatibility
• Filling accuracy and production speed
• Sealing strength and package integrity
• Product handling and contamination prevention
• Coding, batch identification, and traceability

Packaging performance is absolutely critical as the RUTF products will need to survive transport and storage in a variety of difficult distribution environments.

4. Plan the Factory Layout and Production Workflow

A well designed facility will facilitate the movement of materials, people and finished goods.

 

Rather than just laying the machines out according to the available floor space, the layout should be designed around the production sequence and the hygiene requirements.

 

A typical facility may include the following functional areas:

 

• Raw material receiving and storage: An area for receiving, inspecting and storing the ingredients under appropriate conditions.
• Pre-processing area: space for cleaning, sorting, roasting, cooling and grinding.
• Ingredient preparation and mixing area: A dedicated area for weighing, preparing and blending of the ingredients.
• Processing and filling area: A controlled production area for further processing and product packaging.
• Finished product warehouse: A separate warehouse area for packaged products awaiting inspection, release and distribution.

 

The site should also have appropriate personnel access, cleaning facilities, utility connections, ventilation, drainage (where required) and maintenance space.

 

Particular care must be taken to prevent cross contamination between the raw materials and the finished product.

 

For low moisture foods (i.e. conventional RUTF paste) moisture control and hygienic zoning are key considerations. The equipment surfaces, transfer systems and the filling environment itself need to be designed to facilitate effective cleaning and hygiene.

5. Establish Food Safety and Quality Control Systems

Food safety is absolutely a prerequisite for any RUTF manufacturing operation.

 

Buying the right piece of kit in itself won't guarantee that the end product meets the nutritional and microbiological specifications. You need a full quality management system in place covering the ingredients, the processing, the people and the finished product.

 

Important areas include:

 

• Raw material inspection: check supplier qualification, ingredient specification and incoming material quality.
• Process monitoring: Put in place operating procedures and monitor the relevant process parameters (temperature, mixing, product handling etc).
• Microbiological testing: Establish an appropriate testing programme for raw materials, the production environment and the finished product.
• Foreign material control: Use appropriate inspection and detection systems to minimise the risk of physical contamination.
• Packaging integrity: Check the sealing and the package performance to protect the finished product.
• Batch traceability: maintain the production records, ingredient batch info and inspection results to support quality investigations and product tracking.

 

Manufacturers should refer to the Codex Alimentarius Guidelines for Ready-to-Use Therapeutic Foods (CXG 95-2022) together with applicable national regulations and customer specifications.

 

It is also important to work with qualified food scientists and laboratories to validate the formulation, manufacturing process, and finished-product quality.

6. Estimate the Investment and Operating Costs

The investment required to establish a manufacturing facility depends on several factors. There is no single standard price for every project because equipment configurations, production capacities, factory conditions, and regulatory requirements can vary significantly.

The main cost categories generally include:

To obtain a realistic project budget, manufacturers should prepare an equipment list and define their production requirements before requesting quotations.

Comparing suppliers only by the initial machinery price may result in an incomplete investment assessment. It is equally important to evaluate equipment compatibility, automation level, technical support, spare parts availability, and long-term operating costs.
 

7. Choose a Reliable RUTF Production Line Supplier

• Industry experience: Does the supplier have any experience in peanut processing, paste production or the manufacture of specialist food equipment?
• Complete equipment configuration: Can the supplier provide a fully integrated system incorporating cleaning, roasting, grinding, mixing and packaging?
• Customization capability:Can the line be customised to the formulation, factory space and required capacity?
• Automation and control: Does the system enable centralised operation and monitoring of the key production parameters?
• Installation and commissioning: Can the supplier provide technical assistance during installation and equipment testing?
• After sales support: Are the operating instructions, maintenance guidance, spares and technical support available?
