Applications of the 2BE Liquid Ring Vacuum Pump in Food Production and Packaging

The 2BE Liquid Ring Vacuum Pump, with its unique working principle and design, perfectly meets the stringent requirements for hygiene, safety, and efficiency in the food industry, making it an indispensable key piece of equipment.

1.Core Advantages: Why is it Suitable for the Food Industry?

Oil-Free and Clean: Uses water or other permitted liquids as the sealing fluid, eliminating the risk of oil contamination and ensuring compliance with food hygiene standards.

Isothermal Compression: The low-temperature compression process is ideal for handling heat-sensitive products, effectively preserving the food's flavor, color, and nutritional components.

Handles Complex Media: Capable of processing gas streams containing large amounts of water vapor, volatile solvents, or trace solid particles without being easily damaged.

Stable and Reliable Operation: Simple construction, low vibration, and low noise ensure stability for continuous production.

2.Application Scenarios in Food Production

Vacuum Concentration & Evaporation

Application: Concentrating liquid foods like fruit juices, milk, and syrups to reduce volume for transport and storage, or as a step before drying.

Role: Enables boiling at low temperatures, preventing the decomposition of heat-sensitive substances and maintaining natural product quality.

Vacuum Drying

Application: Producing dried fruit and vegetable chips, instant tea powder, protein powder, seasonings, etc.

Role: Low-temperature dehydration better preserves color, aroma, taste, and porous structure, while also improving rehydration properties.

Vacuum Deaeration

Application: Removing dissolved oxygen from liquids like juices, sauces, and edible oils before packaging.

Role: Prevents oxidative spoilage, extends shelf life, and preserves the food's original flavor.

3.Application Scenarios in Food Packaging

Vacuum Packaging

Application: Widely used for packaging meats, cooked foods, cheeses, bean products, etc.

Role: Removes air from the packaging bag, inhibiting the growth of aerobic microorganisms and significantly extending food preservation.

Modified Atmosphere Packaging (MAP)

Application: Used for high-end fresh packaging like salads, prepared meals, and fresh meat/poultry.

Role: The vacuum pump first evacuates air from the package, which is then filled with a specific gas mixture (e.g., nitrogen, carbon dioxide) for optimal preservation.

Skin Packaging

Application: Often used for packaging premium meats, seafood, etc.

Role: By creating a vacuum, the film tightly conforms to the product's surface, showcasing its appearance while ensuring effective preservation.

Selection of Working Fluid

For food applications, choosing the right sealing fluid is critical for absolute safety:

Common Choice: Purified or deionized water.

Special Requirements: Other food-grade certified liquids can be used based on process needs.

Summary

The 2BE Liquid Ring Vacuum Pump, by providing a clean, low-temperature, and reliable vacuum environment, is deeply integrated into various stages of modern food production. It is not merely a tool for efficient production but also a key technological asset for ensuring food quality and safety and enhancing product value, offering robust technical support throughout the entire supply chain from raw material handling to final packaging.
