Vacuum food sealers have become increasingly popular in households, as they extend food freshness by creating a low-oxygen environment through air extraction. Most commercial household models rely on vacuum pumps to achieve this function.
1.1-Miniature Diaphragm Vacuum Pumps Household vacuum sealers primarily use miniature diaphragm vacuum pumps, which offer advantages like compact size, lightweight design, low noise, and oil-free operation. These features make them suitable for home and small commercial use. For example, KYK Technology's KYK27 Series micro diaphragm pumps operate by reciprocating diaphragms to alter chamber volume and transfer gases. They are optimized for applications requiring 1–3.5 L/min flow rates and vacuum levels exceeding 60 kPa. With adjustable speed and signal feedback capabilities, these DC-powered pumps are cost-effective and well-suited for typical household needs.
1.2-Piston Vacuum Pumps Working Principle: Piston pumps generate a vacuum through reciprocating piston motion, compressing and expanding air within the pump chamber.Features: Piston vacuum pumps deliver higher vacuum levels (e.g., >80 kPa) and larger flow rates (e.g., 7–8 L/min) compared to diaphragm models. KYK Technology's KYK28 Series exemplifies this, offering broader applicability for diverse food preservation scenarios. However, they tend to produce slightly more noise and come at a higher cost than the KYK27 Series.
Due to budget and space constraints, motor-driven diaphragm pumps dominate household vacuum sealers. This choice balances product performance with market demands. A home vacuum sealer enhances daily life by prolonging food freshness, preventing odor transfer, and reducing waste.
Vacuum creation via motor-driven pumps eliminates complex control systems, streamlining circuitry and operation. This reduces miniature pump equipment failure rates, enhances reliability, and lowers manufacturing costs. The straightforward design also simplifies maintenance, making these devices user-friendly for long-term use.
