Pumps in Bakery and Diary Industry

Pumps solution for the Bakery Industry

Progressive cavity pumps, also known as single-screw pumps, find significant application in the bakery sector for various purposes related to dough handling and processing. These pumps operate on the principle of a helical rotor turning within a resilient stator, creating a continuous seal along the pumping chamber.

In bakery operations, progressive cavity pumps are commonly used for tasks such as transferring dough from mixing stations to forming or shaping equipment, depositing precise amounts of dough into baking pans or molds, and circulating dough within production lines. Their gentle pumping action ensures that the dough’s integrity is maintained, preventing damage to its structure and consistency.

One key advantage of progressive cavity pumps in bakery applications is their ability to handle viscous and shear-sensitive materials with minimal disruption. This is crucial for maintaining the quality of the dough, especially in processes where precise control over flow rates and pressure is required.

Furthermore, these pumps are often equipped with features such as adjustable speed controls and reversible flow capabilities, allowing for greater flexibility in bakery operations. They can accommodate varying production demands while ensuring consistent and uniform dough handling throughout the process.

Overall, the use of progressive cavity pumps in the bakery industry underscores their importance in optimizing dough handling efficiency, maintaining product quality, and enhancing the overall productivity of bakery operations.

What can you do with Nova Rotors pumps

In the bakery industry, single-screw pumps can be used to pump a variety of materials, including:

  1. Dough: Single-screw pumps can be employed to transfer dough of various consistencies, from softer batter for the production of soft bread and pastries to denser dough used for the production of heartier bread.
  2. Fillings and toppings: They can be used to pump fillings and toppings such as pastry cream, jam, melted chocolate, or other preparations used to fill pastries, cakes, or baked goods.
  3. Glazes and coatings: Single-screw pumps can also be used to pump glazes, coatings, and syrups used to decorate and finish baked goods such as muffins, donuts, and decorated cakes.
  4. Sauces and condiments: They can be used to pump sauces, condiments, and other ingredients used to add flavor or moisture to baked goods, such as pizza sauces, sandwich condiments, or focaccia preparations.

Overall, single-screw pumps offer high precision in dosing and transferring materials, allowing for accurate control of flows and quantities, which makes them useful in a variety of applications in the bakery industry.


Progressing Cavity pumps are also high sanitary standard.

Certainly, another significant advantage of single-screw pumps is their hygienic design. This primarily stems from the fact that many of these pumps are made of stainless steel, a material that is easily cleanable and resistant to corrosion. Additionally, many single-screw pumps are designed in compliance with FDA (Food and Drug Administration) regulations in the United States and 3A Sanitary Standards, which establish hygienic standards for the food and dairy industry.

Compliance with these regulations means that pumps are engineered and constructed to meet rigorous hygienic requirements, ensuring that there are no risks of product contamination during the pumping process. This is particularly crucial in the food industry, where product safety and quality are paramount.

Furthermore, single-screw pumps designed for the food industry often feature additional characteristics to facilitate cleaning and sterilization, such as smooth, crevice-free surfaces, hygienic design, and easy access to components for maintenance. These factors further contribute to ensuring that pumps are safe, hygienic, and compliant with regulations for the food industry, making them an ideal choice for applications in the bakery sector.

The choice of a single-screw pump over other systems depends on the specific needs of the application and the characteristics of the materials to be pumped. However, there are several distinctive advantages to using single-screw pumps:

  1. Material handling gentleness: Single-screw pumps offer a smooth and gentle pumping motion, ideal for materials sensitive to cavitation or component separation. This makes single-screw pumps particularly suitable for transferring delicate dough and other food substances without compromising quality.
  2. Viscosity adaptability: Single-screw pumps can pump materials with a wide range of viscosities, from liquid consistency to highly dense substances. This flexibility makes them suitable for a variety of applications, including those involving denser materials such as creams and glazes.
  3. Dosing precision: Single-screw pumps allow for precise control of flow and pumped quantities, making them ideal for applications requiring accurate dosing, such as depositing fillings or glazes on baked goods.
  4. Reliability and maintenance: Single-screw pumps are generally robust and require minimal maintenance. This reliability is crucial in industrial environments where operational continuity is essential.
  5. Compactness and ease of installation: Single-screw pumps are often compact in size and can be easily integrated into existing systems. This makes them convenient for applications in limited spaces or already operational plants.

In summary, single-screw pumps offer a combination of material handling gentleness, operational flexibility, dosing precision, and reliability that makes them an advantageous choice in many industrial applications, including the bakery sector.
