Application and selection of centrifugal pumps in food processing industry
Uses of centrifugal pumps in the food processing industry
Centrifugal pumps are widely used in the food processing industry, mainly for conveying various fluid materials. Its characteristics include large flow, high pressure, long conveying distance, and the ability to be set in multiple stages according to actual needs to achieve different pressure and flow adjustments. The following are the main uses of centrifugal pumps in the food processing industry:
Conveying fluid materials: Centrifugal pumps can be used to convey fluid materials such as vegetables, juices, sauces, oils, beverages, etc., to meet the requirements of different process flow and pressure in the food processing process.
Jam processing: During the jam processing process, centrifugal pumps can convey fruit puree into syrup to form a uniform jam without damaging the flesh in the fruit.
Beverage production: In beverage production, centrifugal pumps can mix liquids such as milk, juice, and pigments, and then convey them to the filling machine after being processed by a homogenizer to form bottled beverages.
French fries production: During the production of French fries, centrifugal pumps can convey cut potato strips into the fryer, while trying to avoid the potato strips from breaking or deforming during the conveying process.
Selection of centrifugal pumps
When choosing a suitable centrifugal pump in the food processing industry, the following key factors need to be considered:
Understand the properties of the material: including the viscosity, density, temperature, corrosiveness, etc. of the material, which will directly affect the selection of pump body materials, sealing methods, etc. For example, for high-viscosity materials, a pump with a larger impeller diameter and inlet and outlet diameter should be selected to improve the pump's conveying capacity and efficiency.
Clear flow and pressure requirements: According to the needs of the production process, a pump type that can meet the required flow and head should be selected. Flow and pressure are the basic parameters for centrifugal pump selection and are also the key factors in determining the pump type.
Consider equipment materials: Since the food processing industry has strict requirements on product safety and hygiene standards, pump body materials that meet food safety standards, such as stainless steel, PVDF, etc., should be selected. These materials not only have excellent corrosion resistance, but also ensure that the fluid is not contaminated during the conveying process.
Evaluate equipment costs: When choosing a centrifugal pump, it is also necessary to comprehensively consider factors such as equipment price, operating cost, maintenance cost, etc., and choose a product with high cost performance. At the same time, the reliability and service life of the equipment should also be considered to reduce the long-term use cost.
In summary, centrifugal pumps have broad application prospects and important roles in the food processing industry. When selecting a model, you should comprehensively consider factors such as actual production needs, material properties, flow and pressure requirements, equipment materials and costs to select the most suitable centrifugal pump model.
