YH-680-3SQ

Ideal for businesses seeking to enhance food preservation, reduce labor costs, and maintain product quality, the YH-680-3SQ stands out with its robust construction, high precision, and customizable features. Whether handling fresh produce, meats, cooked foods, or seafood, this machine delivers consistent, reliable packaging results, making it a valuable asset for food processing plants, supermarkets, restaurants, and logistics companies.
At the core of the YH-680-3SQ is its ability to create firm, airtight seals that lock in freshness and prevent spoilage. The machine uses advanced sealing technology to ensure that packages remain intact during storage and transportation, minimizing the risk of contamination or quality degradation. This superior sealing capability is critical for maintaining the texture, flavor, and nutritional value of packaged products.
Designed for maximum productivity, the YH-680-3SQ features full automatic sealing functionality, reducing the need for manual intervention and lowering labor costs. Operators can easily set parameters via the intelligent control panel, which presents functions in a clear, user-friendly interface—allowing even new users to get started quickly. This automation not only speeds up the packaging process but also ensures consistent results, eliminating human error.
The machine’s performance is backed by top-tier components:
· AirTAC brand vacuum gauge: Ensures high precision in monitoring and regulating pressure, a key factor in maintaining optimal modified atmosphere conditions.
· Omron high-precision temperature controller (Japan): Delivers intelligent temperature regulation, outperforming low-accuracy controllers from unknown brands. This precision is vital for achieving uniform sealing and preserving product freshness.
· CNC-machined pure aluminum molds: These durable molds support customization to fit different tray sizes and shapes, enhancing versatility for diverse packaging needs.
A standout feature of the YH-680-3SQ is its gas flush accuracy of ±2%—a critical metric for effective modified atmosphere packaging (MAP). By precisely controlling the ratio of gases (such as nitrogen, oxygen, and carbon dioxide), the machine extends product shelf life significantly longer than competitors with larger ratio errors. This accuracy ensures that products stay fresh for extended periods, reducing waste and boosting customer satisfaction.
With a packaging speed of 7-8 circles/min, the YH-680-3SQ boasts a large output suitable for high-volume operations. Its 3KW total power balances efficiency with energy consumption, making it a cost-effective choice for businesses scaling their production. Additionally, the machine’s robust build—weighing 340KG and measuring 166010601430MM—ensures durability even in demanding industrial environments.
The YH-680-3SQ Airflow Modified Atmosphere Packaging Machine is versatile enough to handle a wide range of food products, including:
· Fresh meats (beef, pork trotter, fish meat)
· Seafood (shrimp balls, fish)
· Fruits and vegetables (cherries, leafy greens)
· Cooked foods and ready-to-eat meals
Its ability to adapt to different textures and moisture levels makes it a go-to solution for preserving both raw and processed foods.
· Food processing plants: Streamlines packaging lines for mass production.
· Supermarkets and grocery stores: Extends the shelf life of perishables, reducing restocking frequency.
· Restaurants and catering services: Ensures prepared foods remain fresh during storage and delivery.
· Logistics and distribution: Protects products during transit, maintaining quality from production to end-users.
