定义
The Holding Tube is a critical component in continuous-flow pasteurization systems, designed to maintain beverages at a specific target temperature for a predetermined time to achieve microbial lethality. It ensures uniform heat distribution and precise residence time through controlled flow dynamics, meeting regulatory requirements for food safety while optimizing product quality parameters like flavor, color, and nutritional retention.
工作原理
Operates on the principle of controlled thermal retention: beverages enter at pasteurization temperature and flow through the tube at a calculated velocity, ensuring every particle remains at lethal temperature for the required duration. Laminar/turbulent flow design prevents temperature stratification, while insulation minimizes heat loss to maintain precise thermal profiles.
材料
Food-grade 316L stainless steel (AISI 316L) with electropolished interior surface (Ra ≤ 0.8 μm)external insulation with mineral wool or PIR foam (50mm thickness)and protective aluminum cladding. Optional sanitary fittings use EPDM or PTFE gaskets.

常见问题

How is holding time calculated in a holding tube?

Holding time is calculated by dividing tube volume by flow rate, ensuring every fluid particle meets the required time-at-temperature for pathogen destruction, typically verified through residence time distribution studies.

What maintenance is required for holding tubes?

Regular inspection for surface integrity, CIP cleaning validation, insulation condition checks, and flow calibration to maintain thermal and temporal accuracy.
