Precision gear pump food industry application
Precision gear pumps are widely used in the food industry. Their working principle is to achieve fluid metering and delivery through the movement of gears. The following is a detailed analysis of the application of precision gear pumps in the food industry:
1. Working principle
Precision gear pumps are mainly composed of a drive device, a main structure and a control system. Among them, the main structure includes components such as a pump housing, front and rear side covers, a gear shaft, a sliding bearing and a shaft seal. When a drive device (such as a motor) drives the gear to rotate through a coupling, two meshing gears form a closed volume chamber in the pump housing. As the gears rotate, the closed volume chamber gradually increases, forming a partial vacuum, thereby sucking in liquid. Then, the liquid is transported to the discharge chamber along the gap between the gear and the housing under the push of the gears. In the discharge chamber, as the gears gradually mesh, the closed volume decreases, thereby squeezing the liquid to the discharge port for discharge.
2. Application advantages
Strong conveying capacity: Precision gear pumps can efficiently convey various food materials, including liquids, semi-solids and high-viscosity materials. Its conveying capacity is stable and can meet the requirements for continuity and uniformity of material conveying in the food production process.
Precise metering: Due to the precise meshing of the gears and the optimized design of the pump body structure, the precision gear pump has a precise metering function. It can accurately control the amount of food material delivered in each metering cycle to ensure the accuracy of product quality and composition.
Strong adaptability: Precision gear pumps can adapt to different types of food characteristics and process requirements. Its design and material selection can meet the fluidity and hygiene requirements of different food materials to ensure the quality and safety of the product.
Easy to maintain: The structure of the precision gear pump is relatively simple and it is also relatively convenient to maintain. This helps to reduce the equipment failure rate and improve production efficiency.
3. Application scenarios
Liquid food delivery: such as the delivery and metering of liquids such as milk, juice, and condiments.
High-viscosity food material delivery: such as the delivery and filling of high-viscosity materials such as honey, sesame paste, bean paste, and syrup.
Additive injection: In the process of food processing, it is often necessary to add some auxiliary agents and additives to the food materials, such as seasonings, pigments, preservatives, etc. Precision gear pumps can accurately control these doses and inject them into the food materials to ensure the uniform distribution and stability of the additives.
4. Precautions
Material selection: When selecting a precision gear pump, materials that meet food safety standards should be given priority to ensure the safety and applicability of the product.
Maintenance: Regularly perform maintenance on the precision gear pump, such as cleaning and lubrication, to extend the service life of the equipment and maintain its good working condition.
Operation specifications: When operating a precision gear pump, relevant operating procedures and safety specifications should be followed to ensure the normal operation of the equipment and the safety of personnel.
