Which Food Screw Pump Ensures Smooth and Efficient Food Transfer?​

What Type of Food Screw Pump is Suitable for Viscous Materials Like Syrups or Pastes?​

Viscous food materials such as syrups, chocolate pastes, or fruit purees require screw pumps with specific design features to ensure smooth transfer. Progressive cavity screw pumps are often the ideal choice here. Their rotating rotor and fixed stator create a series of sealed cavities that move the material forward without excessive shear, preventing the material from being damaged or losing its texture. For example, when transferring high - viscosity honey, a progressive cavity screw pump with a wide - pitch rotor can reduce the resistance during transfer, ensuring a consistent flow rate without clogging. In contrast, centrifugal pumps may struggle with viscous materials, as they rely on high - speed rotation to generate pressure, which can lead to uneven flow or even material buildup in the pump.​

How to Ensure That a Food Screw Pump Meets Hygienic Standards for Food Processing?​

Hygiene is a top priority in food processing, so the design and materials of a food screw pump must adhere to strict hygienic standards. First, the pump should be made of food - grade materials such as 316L stainless steel, which is corrosion - resistant and easy to clean. The surface of the pump's internal components should be polished to a smooth finish (with a roughness Ra value of less than 0.8 μm) to prevent food residues from adhering. Additionally, the pump should have a modular design that allows for easy disassembly and cleaning. For instance, some food screw pumps feature quick - release clamps that enable workers to take apart the pump without using specialized tools, making it easier to clean every nook and cranny. The pump should also be compatible with common cleaning methods in the food industry, such as CIP (Clean - in - Place) systems, which can automatically clean the pump without disassembly, saving time and ensuring thorough cleaning.​

What Features Should a Food Screw Pump Have to Handle Abrasive Food Materials Like Nuts or Seeds?​

Abrasive food materials like chopped nuts, sesame seeds, or grain mixtures can cause wear and tear on the pump's internal components over time, affecting its performance and lifespan. To handle these materials, a food screw pump should have wear - resistant components. The rotor and stator, which are in direct contact with the material, can be made of high - wear - resistant materials such as hardened stainless steel or polyurethane. Some pumps also have a replaceable liner in the pump housing, which can be easily replaced when it becomes worn, reducing maintenance costs. Another important feature is a large - diameter inlet and outlet. A wide inlet can prevent the abrasive particles from getting stuck at the entrance, while a large - diameter outlet can ensure that the material flows out smoothly without accumulating and causing abrasion. For example, when transferring a mixture of nuts and dried fruits for cereal production, a food screw pump with a 3 - inch inlet and outlet and a polyurethane stator can handle the abrasive particles effectively, maintaining a stable flow rate for long - term operation.
