Description

The Thermal Processing Solution for Ambient-Stable Foods

The LR-500 Automatic Rotary Hot-Fill Monoblock is engineered to address the core challenge of preserving low-acid and viscous foods. For food manufacturers across Southeast Asia, Africa, the Middle East, and Latin America, where ambient shelf-stability can drastically reduce cold chain costs and expand market reach, this machine provides a critical thermal processing step. By filling products at pasteurization temperatures directly into containers, it inactivates spoilage microorganisms and enzymes. The subsequent cooling of the sealed container creates a vacuum, ensuring container integrity and significantly prolonging shelf-life without chemical preservatives.

The Hot-Fill Advantage: Safety, Quality & Efficiency

• Integrated Thermal Management: The product pathway, including the filler bowl, manifolds, and pumps, is jacketed or trace-heated to maintain precise product temperature from the cooker to the point of fill, preventing temperature drop that could compromise safety or viscosity.

• Particulate Handling: Designed with wide-diameter valves and smooth product pathways to gently handle products containing fruit chunks, vegetables, or meat pieces (as in stews or ragù) without damaging particulates or causing blockages.

• Vacuum Creation: Capping is performed immediately on the hot product. As the product cools, it contracts, naturally pulling down the cap’s button or creating a vacuum under the lid—a visual and functional indicator of a proper seal and product safety.

Technical Specifications for Viscous & Particulate Products

• Machine Type: Fully Automatic Rotary Monoblock with Integrated Hot-Fill System.

• Process: Hot-Fill-Hold technology for ambient shelf-stable products.

• Filling Technology: Rotary piston or pump filler, designed for high-viscosity and particulate-laden products.

• Temperature Control: Jacketed product tank and pathways with thermal fluid or electric heating to maintain fill temperature (±1°C).

• Capping Technology: Rotary capping head with cap orienter for screw caps, twist-off lids, or press-on caps.

• Container Compatibility: Glass jars and plastic (PP, PET) containers of various sizes, from small portion packs to large family jars.

• Output Speed: High-speed rotary platform suitable for medium to large-scale food production.

• Construction: Full food-grade, hygienic design. All product contact parts are AISI 304 or 316L Stainless Steel, polished. Designed for easy disassembly and cleaning.

• Cleaning: Full CIP (Clean-in-Place) capability to handle sticky residues and ensure hygiene.

• Control System: Advanced PLC with Touchscreen HMI for precise control over fill volume, temperature, and production parameters, with recipe storage for different products.
