Below are a few case studies from different industries that showcase how lab extruders have contributed to innovations and improved processes:
1. Case Study: Food Industry – Development of New Snack Products
Company: A global snack food manufacturer
Objective: To develop a new line of healthy, extruded snack products with high fiber content and improved taste.
Challenge: The company wanted to create a range of healthier snack options with minimal oil content, higher fiber, and improved taste profiles to meet growing consumer demand for healthier alternatives. They needed a process that could handle various ingredients (such as whole grains, fiber, and plant-based proteins) and deliver consistent texture and flavor.
Solution: The company utilized a laboratory-scale food extruder to develop multiple prototypes of snacks using a variety of ingredients. The extruder allowed them to fine-tune processing conditions (e.g., temperature, screw speed, moisture content) to optimize the product’s texture and flavor. By adjusting parameters in real-time, they were able to control the puffing behavior of the product, ensuring an appealing texture.
Impact:
• Faster Product Development: The lab extruder enabled quick testing and iteration of different formulations, reducing the development time by 30%.
• Improved Product Quality: The new snacks had a consistent texture and flavor, meeting the desired product characteristics.
• Reduced Costs: By using small-scale production trials, the company minimized raw material wastage, saving on the costs of large-scale trials.
Outcome: The company successfully launched a new line of healthy, extruded snacks, which gained popularity in the market, increasing sales in the healthier snack category by 15%.
2. Case Study: Pharmaceuticals – Development of Hot-Melt Extrusion for Drug Delivery
Company: A pharmaceutical company specializing in controlled-release formulations
Objective: To develop a novel oral drug delivery system for a poorly soluble drug using hot-melt extrusion (HME).
Challenge: The pharmaceutical company was faced with the challenge of developing a formulation for a poorly soluble active pharmaceutical ingredient (API) to enhance its bioavailability and controlled release in the body. Traditional methods of formulation had not been successful in achieving the desired release profile.
Solution: The company turned to lab-scale hot-melt extrusion to develop the new drug formulation. The extruder enabled them to mix the API with excipients (such as polymer matrices) and extrude the mixture into controlled-release pellets. The hot-melt extrusion process allowed the company to overcome the solubility issue by creating a stable solid dispersion of the drug in a polymer matrix, which facilitated better absorption in the body.
Impact:
• Enhanced Drug Solubility: The lab extruder successfully enhanced the solubility and bioavailability of the poorly soluble drug, improving its therapeutic effectiveness.
• Improved Controlled Release: The extrusion process allowed precise control over the release rate of the drug, leading to an extended release profile that aligned with the product’s therapeutic goals.
• Faster Time to Market: The lab extruder enabled faster development of the new drug formulation by reducing the time needed to scale up the process.
Outcome: The company successfully launched the new oral drug product with improved solubility and controlled release, which was approved by regulatory bodies. The drug received positive feedback from both healthcare professionals and patients, boosting the company’s product portfolio.
3. Case Study: Polymer Industry – Compounding of Biodegradable Polymers
Company: A materials science research company specializing in sustainable plastics
Objective: To develop a new biodegradable polymer for use in eco-friendly packaging solutions.
Challenge: The company needed to develop a biodegradable plastic that maintained comparable strength, durability, and processing properties to traditional plastics like polyethylene (PE) but was environmentally friendly and could break down more easily after use.
Solution: The company used a lab-scale twin-screw extruder to compound biodegradable materials, including starch-based and polyhydroxyalkanoate (PHA) polymers, with various additives to improve processing, strength, and flexibility. The extruder allowed them to experiment with different formulations, extrusion conditions, and mixing intensities to create a composite material that met performance standards for packaging.
Impact:
• Material Innovation: The lab extruder enabled the development of a biodegradable polymer blend that maintained desirable properties like strength and flexibility, making it suitable for packaging applications.
• Customization of Properties: The team could fine-tune the formulation to optimize the material’s performance under different conditions, such as moisture resistance and temperature stability.
• Cost Savings: Small-scale experimentation helped minimize raw material waste, making the development process more cost-effective.
Outcome: The company successfully developed a sustainable and biodegradable plastic material that was later adopted by a major consumer goods company for packaging. This move helped the company meet its sustainability goals and respond to growing consumer demand for eco-friendly products.
4. Case Study: Food Industry – Development of Meat Analogs (Plant-Based Proteins)
Company: A plant-based food startup
Objective: To develop a plant-based meat alternative with texture and flavor similar to real meat.
Challenge: The startup was aiming to create a realistic meat alternative for vegetarians and vegans. The challenge was to replicate the texture, flavor, and appearance of meat using plant-based ingredients while maintaining a nutritious profile.
Solution: The startup utilized a lab-scale twin-screw extruder to process various plant proteins (e.g., pea protein, soy protein, wheat gluten) and create a fibrous, meat-like texture. The extruder allowed for fine control of the temperature, pressure, and screw configuration to optimize the texture and mouthfeel of the final product. Multiple formulations were tested, with the extruder providing the flexibility to experiment with different protein sources and processing conditions.
Impact:
• Texture Optimization: The lab extruder enabled the development of a plant-based meat analog that mimicked the texture and mouthfeel of traditional meat, enhancing its appeal to consumers.
• Flavor Enhancement: By controlling processing parameters such as moisture content and temperature, the team was able to enhance the flavor profile, making it more meat-like.
• Faster Product Iteration: The ability to quickly test different formulations and processes led to faster iterations, helping the company refine its product.
Outcome: The startup successfully launched its plant-based meat alternative, which gained traction in the market due to its realistic texture and flavor. The product was eventually picked up by several major grocery chains, expanding the company’s reach and contributing to the growing trend of plant-based food products.
5. Case Study: Automotive Industry – Production of Thermoplastic Composites
Company: An automotive manufacturer
Objective: To develop lightweight, durable composite materials for automotive parts to reduce vehicle weight and improve fuel efficiency.
Challenge: The manufacturer wanted to replace traditional metal parts with lightweight thermoplastic composites, which could maintain the strength and durability required for automotive applications while being more cost-effective and environmentally friendly.
Solution: The manufacturer used a lab-scale twin-screw extruder to develop and compound thermoplastic composite materials, integrating carbon fibers with polymer matrices to create lightweight yet strong materials.
