Vertical Counter‑Pressure Retort LS‑35L/50L/75L/100L | Dual‑Mode Sterilization for Food Packaging Aseptic Testing LS‑series Vertical Counter‑Pressure Retort for Food Packaging Sterilization & Laboratory Aseptic Validation Product Introduction Reliable dual‑mode counter‑pressure sterilizer tailored for food packaging quality control & lab aseptic evaluation. The vertical counter‑pressure retort is a medium‑small‑size mechanically program‑controlled counter‑pressure sterilization equipment. The sterilizer adopts electric heating mode. Water is directly injected into the sterilizing chamber and heated to generate high‑pressure steam required for sterilization to disinfect articles. After sterilization is completed, external compressed air and water pressure are applied for rapid cooling within 3 minutes, cooling internal articles down to 30‑40℃. Equipped with program control, it supports two operation modes: boiling disinfection and pressure sterilization with rapid cooling. Boiling temperature can be set ≤100℃. The rapid‑cooling pressure sterilization temperature is pre‑selectable within 101℃‑135℃. It is integrated with heater overload protection and buzzer alarm upon sterilization completion. Featuring simple operation and high safety reliability. This unit is suitable for disinfection and sterilization of food packaging, utensils and instruments. It is an ideal device especially for aseptic tests in food research institutions. Working Principle Dual‑sterilization logic enables boiling disinfection & high‑pressure counter‑pressure sterilization, simulating real‑world thermal processing conditions for flexible packaging samples. This equipment is designed with two disinfection & sterilization principles to deliver dual‑function performance for customers. The heater directly heats water to produce pressurized steam. The pressurized steam acts on microorganisms on samples and destroys their structures to realize sterilization. When rapid‑cooling sterilization program starts, 6 liters of tap water is first injected into the chamber. After around 25‑minute heating process, it enters sterilization holding stage with sterilization duration of 35‑40 minutes. When sterilization finishes, 0.24 MPa compressed air and tap‑water pressure are manually fed into the chamber, then half‑open the drain valve to discharge water and implement counter‑pressure cooling for flexible packages and other specimens. Rapid cooling lasts for 3 minutes. Manually cut‑off compressed air and tap‑water supply, and internal articles can be cooled down to 30‑40℃.
