High Viscosity Products Include…

Nut Butters, Dermatological  Creams, Chutneys and Relishes, Body Butters, Hummus, Thick Sauces, Body Scrubs, and more.

 

1. Invest in High-Quality Equipment Which is Fit for Purpose:

When dealing with high-viscosity materials, selecting the right equipment first time is crucial. Dean recommends investing in robust mixers, pumps and filling equipment which has been proven to work with thick substances. Cheaper options are likely to be a false economy in the long run.

When looking to buy new equipment, ask potential suppliers to provide case studies of their equipment working with similar products to yours. Even better would be conducting a demonstration on their equipment, using your product. Some suppliers will even be able to take you to see the equipment in-action at another customers’ site.

Quality equipment not only ensures smooth production, but also minimises wear and tear, reducing downtime and maintenance costs.

2. Optimise Your Mixing Techniques:

Proper mixing is the key to achieving uniform viscosity and product quality. This means that your customers will always have a great experience of your product. Inconsistent mixing could mean that some batches are different thicknesses or lumpy, which could stop your customers from repeat purchasing.

Consider using techniques like shear mixing, which applies force to break down particle agglomerations, and high-shear mixing, which involves high-speed rotation to disperse materials evenly. Your mixing equipment supplier will be able to recommend the ideal type of mixing to best suit your product.

Experiment with mixing speeds and durations to find the optimal parameters for your specific product.

 

3. Maintain Consistent Temperatures:

Viscosity is highly temperature-dependent, and thicker products often mix or fill better when heated. Maintaining consistent temperatures throughout the stages of your manufacturing process is crucial for controlling the flow properties of your product. For example, water-jacketed mixing vessels use hot water flowing around the vessel ‘jacket’ to regulate temperatures during mixing. Ideally, finding one single supplier who can offer both mixing and filling equipment can ensure a smoother production process. For example, Adelphi’s Response Benchtop Filler can be supplied with a water jacketed hopper where the product waits to be filled.

Real-time temperature monitoring and control mechanisms can prevent overheating or cooling, ensuring the product maintains its desired viscosity.

 

 

4. Implement Quality Control Measures:

Establish rigorous quality control protocols to monitor viscosity, texture, and other relevant parameters at various stages of production. Utilise viscometers and rheometers to measure viscosity accurately. Implement in-process testing to detect inconsistencies early, allowing for immediate adjustments. Regularly calibrate your measurement instruments to maintain accuracy. Document and analyse quality data to identify patterns and optimise the manufacturing process continuously.

 

5. Focus on Safety and Cleanliness:

Thick, high-viscosity materials can be challenging to handle and clean. Prioritise safety by providing employees with proper training and personal protective equipment (PPE). Implement safety protocols to prevent accidents and spills. Additionally, design your equipment and production layout with easy cleaning in mind. Use materials that resist sticking and are easy to clean, such as stainless steel.

Regularly schedule equipment cleaning and maintenance to prevent product contamination and ensure the longevity of your machinery. Ask potential filling machinery suppliers how long it takes to strip and clean their equipment, as any time spent not filling represents lost revenue potential for your business. For example, purchasing a machine which has a longer strip and clean time would be less cost-effective in the long run.
