The KN-GRL300 Automatic Vacuum Tumbler with Lung-Breathing Technology is a premium industrial marinating system developed for commercial meat processors seeking maximum product quality and production efficiency.
Unlike conventional vacuum tumblers, the KN-GRL300 incorporates lung-breathing vacuum technology, which alternates between vacuum and atmospheric pressure during the tumbling cycle. This pulse-vacuum process repeatedly expands and contracts the meat fibers, allowing marinades to penetrate more deeply and evenly while improving protein extraction, water retention, tenderness, and final product yield. This intermittent vacuum approach creates a sponge-like effect that increases marinade uptake and processing efficiency compared with continuous vacuum alone.
The programmable automatic control system manages tumbling direction, vacuum cycles, tumbling time, and resting intervals, ensuring repeatable processing for a wide variety of products.
Manufactured entirely from food-grade SUS304 stainless steel, the KN-GRL300 is engineered for continuous industrial production in modern meat processing facilities.

FAQ
1. What is lung-breathing vacuum technology?
It is a pulse-vacuum process that alternates between vacuum and atmospheric pressure, repeatedly expanding and contracting meat fibers to improve marinade absorption, tenderness, and water retention.
2. What products can the KN-GRL300 process?
It is suitable for pork, beef, poultry, seafood, BBQ products, skewers, steaks, and ready-to-cook foods.
3. Does vacuum tumbling improve product yield?
Yes. Vacuum tumbling increases protein extraction, moisture retention, and marinade uptake, resulting in higher yield and more consistent product quality.
