200L 300L 500L Milk Pasteurizer Cooler Tank

A Milk Pasteurizer Cooler Tank is an integrated piece of dairy equipment designed for pasteurizing and rapidly cooling milk. It is essential for ensuring milk safety and extending shelf life by eliminating harmful microorganisms. Tanks in the 200L to 500L range are ideal for small to medium-scale operations, including boutique dairy farms, artisanal cheesemakers, and small processing plants.

Core Features and Working Principle

These tanks combine several key functions into one system:

Integrated Pasteurization and Cooling: The core function is to first heat the milk to a specific pasteurization temperature (commonly 72°C for 15 seconds or 63°C for 30 minutes) and then cool it rapidly to a safe storage temperature (around 4°C) within the same vessel. This process preserves quality and safety.

Construction and Materials: They are almost exclusively constructed from high-grade stainless steel (SUS304 or 316L), which is durable, corrosion-resistant, and meets food hygiene standards. The walls are typically double-layered with insulation in between to maintain temperature.

Automation and Control: Modern units feature programmable logic controller (PLC) systems for precise control over time, temperature, and process steps. They often include automatic cleaning (CIP) systems for hygiene and agitation systems to ensure even heating and cooling.

Cooling Mechanism: Most tanks in this category use a direct-expansion cooling system. Refrigerant circulates in an evaporator panel in direct contact with the tank's inner wall, efficiently removing heat from the milk.

Typical Applications

These versatile tanks are used in various settings:

On Farms: For processing and cooling raw milk directly after milking.

In Small Dairies: For producing pasteurized bottled milk, cream, or as the first processing step for cheese and yogurt.

In Research Labs: For developing new dairy products and processes on a pilot scale.
