Thick sauces such as peanut butter, chili sauce, tomato paste, jam, and other viscous foods can easily stick to the kettle wall during cooking. With ordinary stirring, the center of the product may move well while material near the wall remains relatively stationary. This can cause sticking, local overheating, product loss, and extra cleaning work. A planetary cooking kettle provides a more effective way to keep thick products moving while scraping material from the kettle wall.
Why Do Thick Sauces Stick to the Kettle?
High-viscosity products do not flow as easily as water-like liquids. During heating, the sauce near the kettle wall may move slowly and remain in contact with the heated surface for too long.
As the product becomes thicker, ordinary stirring may not reach every area of the kettle effectively. Material can gradually build up on the wall or bottom, making subsequent cleaning more difficult.
What Happens When Sauce Builds Up?
When thick sauce remains on a heated surface, it can become overheated or even burn. This may affect the appearance, flavor, and consistency of the product.
At the same time, sauce stuck to the kettle wall becomes difficult to remove, increasing product waste. Workers may also need to stop production and manually clean the kettle before the next batch.
Use Scraping to Keep the Kettle Wall Clean
One way to reduce sticking is to continuously move material away from the kettle wall. A planetary cooking kettle uses a planetary mixing system that rotates through the product while the mixing components move around the kettle.
With suitable scraping components, material close to the wall can be continuously brought back into the mixing area instead of remaining on the heated surface.
Improve Mixing and Heating Uniformity
For thick sauces, simply increasing the stirring speed is not always the best solution. The product needs to be continuously mixed throughout the kettle so that heat and ingredients are distributed more evenly.
Planetary mixing provides movement across different areas of the kettle, helping reduce stagnant zones and improving the consistency of thick products during cooking.
Reduce Manual Cleaning and Product Loss
When less product accumulates on the kettle wall, operators spend less time scraping and cleaning the equipment after production. More of the processed sauce can also remain in the product instead of becoming difficult-to-recover residue.
For businesses producing thick sauces continuously or in large batches, reducing cleaning interruptions can improve overall production efficiency.
Choose a Planetary Cooking Kettle for Thick Products
If your production involves peanut butter, sauces, pastes, fillings, jams, or other viscous products, a planetary cooking kettle can provide both cooking and intensive mixing while helping reduce wall sticking.
The suitable kettle should be selected according to your product viscosity, batch capacity, heating requirements, and production process. Send us your product type, batch size, and heating requirements, and we can recommend a suitable planetary cooking kettle and provide a customized solution.
