Advantages of the Conical Cup Stirrer

Conical cup stirrers are widely used in the food industry (liquid sugar, dressings, sauces), as well as in the chemical industry (additives, coatings) and biotechnology. Compared to other common stirring elements, they offer the following advantages:

• Low shear forces: Cup stirrers mix gently at low speeds
• No foam formation: The cup stirrer does not generate foam or introduce air into the product.
• No flow breakers: No thrombus formation occurs, and flow breakers are not necessary.
• Cleaning & Maintenance: Cup stirrers are easy to operate and maintain, making them a practical solution for industrial use.
• High flexibility: Cup stirrers are versatile and suitable for a wide range of viscosities and stirring tasks.
• No heating of the medium: The gentle stirring process does not heat the product, which can offer process advantages.

One disadvantage of the cup stirrer is that it can only be operated effectively at a fill level of around 2/3 of the tank volume. For low fill levels or continuous operation, the cup stirrer is not ideal.

How does the backpressure system of the cup stirrer work?

The conical cup blades of the cup stirrer generate increased pressure in the cones during the stirring process. A liquid cushion forms in front of the cone, while in the rear part of the cone, an accelerated flow results. This principle is also known as the Venturi effect. As a result, a turbulent mixing action occurs in the tank, ensuring gentle and highly efficient mixing.

Cup Stirrer for Various Stirring Tasks

Cup stirrers are particularly suitable for processing liquid to medium-viscous media, such as up to 2,000 mPas. They are especially effective for:

• Liquids
• Suspensions and emulsions
• Stirring tasks in laboratories and pilot plants
