High-Performance Double Chamber Vacuum Packaging Machine for Chestnuts

This industrial-grade vacuum packaging machine is the essential solution for producers aiming to maximize the shelf life and quality of raw, peeled, or pre-cooked chestnuts. By achieving a superior, oxygen-free environment, it ensures the chestnuts retain their flavor, texture, and nutritional value long after processing.

Key Preservation Benefits for Chestnuts

• Extended Shelf Life: The deep, consistent vacuum removes oxygen, effectively slowing the natural oxidation process that causes fats to become rancid and degrade the chestnuts delicate flavor and texture.³

• Protection Against Spoilage: The hermetic seal and low-oxygen environment suppress the growth of mold and bacteria, vital for both raw and high-moisture pre-cooked products.⁴

• High Production Efficiency: The dual-chamber design allows for continuous operationoperators load one chamber while the other completes the vacuum and sealing cycleeffectively doubling throughput and minimizing downtime during peak season.

• Moisture Control: The tight, professional seal prevents moisture exchange, whether protecting the chestnuts from external humidity or helping to retain their natural moisture content.

Operational Features

• Powerful Vacuum Pump: Equipped with a high-capacity pump to rapidly pull a deep vacuum, suitable for both smaller retail bags and larger bulk portions of chestnuts.

• Durable Sealing: Features robust sealing bars (often with a double-seal option) to ensure a strong, reliable bond on specialized packaging films (like multi-layer plastic or foil) used for maximum preservation.

• Stainless Steel Build (SUS 304): Constructed from food-grade stainless steel, making it ideal for the often damp and demanding environment of food processing and easy to clean to maintain strict hygiene standards.
