VM400TEA&VM400TEB

VM400TEA & VM400TEB Double Chamber Vacuum Packaging Machine

Product Description

The SunAura VM400TEA and VM400TEB are double chamber vacuum packaging machines designed for medium to high-volume food packaging operations. These machines feature two vacuum chambers that alternate during operation, allowing continuous packaging without waiting for the vacuum cycle to complete. While one chamber is under vacuum, the operator can load and unload products in the other chamber, significantly increasing production efficiency compared to single chamber machines.

The VM400TEA model features a standard flat chamber lid, while the VM400TEB model includes a domed chamber lid for packaging taller products. Both models use imported Schneider and OMRON electrical components for reliable performance. The 400mm sealing length accommodates larger bags and multi-product packaging. The machines are constructed with 304 stainless steel chambers for corrosion resistance, food safety, and long service life in demanding food processing environments.

Applications of Double Chamber Vacuum Packaging Machine

• Meat Processing: Vacuum packaging for fresh meat, cured meats, sausages, and poultry products. Double chamber design enables high-volume meat packaging for butcher shops and meat processing facilities.
• Seafood Processing: Packaging fresh and frozen seafood including fish fillets, shrimp, and shellfish. Vacuum sealing prevents freezer burn and extends seafood shelf life.
• Cheese and Dairy: Vacuum packaging for cheese blocks, butter, and dairy products. The domed lid model (VM400TEB) accommodates taller cheese wheels and blocks.
• Prepared Foods: Packaging ready meals, cooked foods, and meal kits for retail and food service. Vacuum sealing preserves flavor and extends shelf life of prepared foods.
• Vegetable and Fruit Packaging: Vacuum sealing for fresh produce, pre-cut vegetables, and fruit products to extend shelf life and maintain freshness.
• Industrial Products: Vacuum packaging for electronic components, metal parts, and industrial products requiring moisture and oxidation protection.

Double Chamber vs Single Chamber: Efficiency Comparison

Double chamber vacuum packaging machines offer significant efficiency advantages over single chamber models. In a single chamber machine, the operator must wait for the vacuum cycle to complete (typically 20-40 seconds) before opening the lid, removing the packaged product, and loading a new one. This results in significant idle time during each cycle.

In a double chamber machine, the two chambers alternate. While one chamber is undergoing the vacuum and sealing cycle, the operator can simultaneously load products into the other chamber. This overlapping operation can increase throughput by 60-80% compared to single chamber machines. For operations processing more than 100 packages per hour, a double chamber machine is strongly recommended.

The VM400TEA and VM400TEB models offer the same chamber size and sealing length, with the only difference being the lid design. The VM400TEA flat lid is suitable for flat products such as meat fillets, cheese slices, and prepared food trays. The VM400TEB domed lid accommodates taller products such as whole chickens, cheese wheels, and bulk food containers.

Frequently Asked Questions

What is the difference between VM400TEA and VM400TEB?

The VM400TEA features a flat chamber lid with a chamber height of 130mm, suitable for flat products such as meat fillets, cheese slices, and food trays. The VM400TEB features a domed chamber lid with a chamber height of 200mm, designed for taller products such as whole poultry, cheese wheels, and tall containers. Both models have the same chamber footprint (420x420mm), sealing length (400mm), and vacuum pump capacity (20 m3/h). Choose the TEA for flat products or the TEB for taller products.

How many packages can the machine process per hour?

The double chamber design enables processing of approximately 200-300 packages per hour, depending on product type, bag size, and vacuum settings. Each vacuum cycle takes 20-40 seconds, and the alternating chamber operation allows loading/unloading during the vacuum cycle. For optimal throughput, we recommend pre-loading products into bags before starting the machine and using consistent bag sizes.

What type of vacuum pump does the machine use?

The VM400TEA and VM400TEB use a rotary vane oil-sealed vacuum pump with a capacity of 20 m3/h. This pump provides fast air evacuation and can achieve an ultimate vacuum of -0.1 MPa. The oil-sealed design ensures reliable operation and long pump life. The pump oil should be checked weekly and changed every 500 hours of operation or every 3 months, whichever comes first. We provide spare pump oil and replacement filters with each machine.

Can the machine handle products with sharp edges?

Yes, but we recommend using thicker vacuum bags (0.15-0.20mm / 6-8 mil) for products with sharp edges such as bones, shellfish shells, or metal parts. For extra protection, bone guard strips can be placed over sharp edges before vacuum sealing. The 304 stainless steel chamber is resistant to punctures and scratches, but care should be taken to prevent bag punctures that could compromise the vacuum seal.

Does the machine support gas flushing (MAP)?

The standard VM400TEA and VM400TEB models do not include gas flushing capability. However, we offer an optional gas flushing (Modified Atmosphere Packaging) upgrade that injects nitrogen or mixed gas into the bag after vacuuming and before sealing. This is useful for products that require a protective atmosphere to maintain color, texture, or freshness. contact us for pricing and availability of the gas flushing option.

What is the power consumption of the machine?

The VM400TEA and VM400TEB have a power rating of 1.5 KW, which includes the vacuum pump motor, heating element, and control system. The machine operates on 220V or 380V power supply (selectable at installation). Average power consumption during operation is approximately 1.0-1.2 KW, with peak consumption during the vacuum pump startup. The machine is energy efficient, with the vacuum pump automatically shutting off between cycles.

What maintenance is required?

Daily maintenance includes cleaning the chamber and sealing bar, and checking pump oil level. Weekly maintenance involves inspecting the lid gasket for wear, cleaning the vacuum pump exhaust filter, and lubricating the lid hinge mechanism. Monthly maintenance includes changing the vacuum pump oil, inspecting electrical connections, and checking the sealing bar for wear. We provide a maintenance manual, spare parts kit, and ongoing technical support with each machine.
