Ultra-high temperature instantaneous sterilizer

Product Details

Product Introduction

The ultra‑high‑temperature short‑time sterilizer employs a helical double‑coil design to achieve rapid, high‑temperature sterilization of fluid materials. This equipment not only eliminates microorganisms but also preserves the product’s flavor and nutritional value. When paired with a homogenizer, it is suitable for processing highly viscous products such as beet milk concentrate.

Working principle

The material is pumped into the outer channel of the double‑walled coil, where it is preheated by indirect heat transfer from the hot fluid flowing through the inner channel. Upon entering the high‑temperature coil housed within the sterilization vessel, the material is further heated to the required sterilization temperature via indirect steam heating inside the vessel. It is then held at this temperature in the single‑walled coil outside the vessel to ensure complete microbial inactivation. As the material returns to the double‑walled coil, it flows through the inner channel and is cooled by the cold fluid in the outer channel, resulting in a significant reduction in the outlet temperature.

Product Applications

Ultra‑high‑temperature short‑time sterilizers are suitable for the instantaneous sterilization of liquid products such as dairy products, beverages, soy milk, seasonings, pharmaceutical solutions, fresh milk, fruit juices, popsicles, ice cream mixtures, soybean milk, and condensed milk. Because the heating time is extremely brief, nutrient loss is minimal, making these systems widely used for sterilizing fluid foods and drinks like fresh milk, soy sauce, and alcoholic beverages.
