This series of vacuum packaging machines has the characteristics of vacuum, sealing, and automatic cooling processing. It can prevent product oxidation and mold, as well as corrosion and moisture, maintain the freshness of food, and extend storage time.
Frequently Asked Questions
Q:
What items can be packaged using these chamber vacuum sealers?
These machines are highly versatile and ideal for vacuum packaging fresh meats, seafood, vegetables, fruits, dry goods, electronic components, and medical instruments to protect them from oxidation, mold, and humidity.
Q:
What is the advantage of the 304 Stainless Steel construction?
The 304 SS case and hull ensure excellent corrosion resistance, high durability, and ease of cleaning. This structural choice fully complies with strict international food hygiene and safety standards.
Q:
How do I choose between the 220V and 380V voltage models?
Smaller and medium models (like TDDZ-240, TDDZ-300, and TDDZ-400-1) operate on single-phase 220V power, suitable for standard commercial settings. Large, high-capacity industrial machines (such as DZ-400/2SD, TDDZ-600/2SE, and TDDZ-800/2SC) require 380V power to support higher pump capacity.
Q:
What does "lowest absolute pressure 0.1Pa" mean for food preservation?
An absolute pressure level of 0.1Pa indicates a highly efficient air extraction process. Removing almost all oxygen inside the chamber prevents the growth of aerobic bacteria, thereby locking in freshness and significantly extending food shelf life.
Q:
Are these vacuum packaging machines built for continuous industrial workload?
Yes, they are manufactured with heavy-duty commercial-grade components and a precise electric control system. This ensures robust continuous operations and stable long-term performance under demanding business conditions.
