Homogenizer Unit for UHT Sterilization Lines

Product Specifications

Technical details and manufacturing context for Homogenizer Unit

Definition

The Homogenizer Unit is a critical component of the Automated Ultra-High Temperature Sterilization Line designed to process liquid food products. It functions by forcing the product through a narrow gap at high pressure, breaking down fat globules and other particles to create a stable, uniform emulsion. This process prevents cream separation, improves texture and mouthfeel, and enhances product stability throughout shelf life. Within the sterilization line, it typically operates after initial heating stages but before final UHT treatment to ensure microbial reduction effectiveness. The unit is constructed with product-contact parts in stainless steel 316L, hardened alloy steel for wear resistance, and ceramic seals for durability. It operates within a pressure range of 1.0–1.6 MPa, with a flow capacity of 5000–20000 L/h depending on line throughput. Homogenization efficiency is at least 95%, achieving a final mean particle size of ≤2 µm. The product temperature range is 4–85 °C, and power consumption varies from 15–45 kW. Electrical supply is three-phase 380–480 V AC (IEC 60038). The unit has an ingress protection rating of IP54–IP65 (IEC 60529) for washdown environments. Weight ranges from 800–1500 kg, and approximate dimensions are 1200×800×1500 mm (L×W×H). Seals are EPDM, FDA compliant. These parameters are reference values; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model and application. The unit is not a standalone product but an integral part of the sterilization line, and its selection depends on factors such as product type, desired emulsion quality, and line capacity. Verification of performance and compliance with applicable standards should be conducted during procurement and installation.

Working Principle

The homogenizer operates on the principle of high-pressure mechanical shearing. Liquid product is pumped through a homogenizing valve assembly consisting of a valve seat and valve. As the product passes through the extremely narrow gap (typically 0.1-0.2 mm) between these components at pressures ranging from 100-300 bar, intense turbulence and cavitation occur. This mechanical action breaks down fat globules from 3-8 microns to sub-micron sizes (0.5-1 micron), creating a stable, homogeneous emulsion. The process also disrupts microbial cells, contributing to the overall sterilization effectiveness.

Frequently Asked Questions

What materials are used for product-contact parts?

Product-contact parts are made of stainless steel 316L (ASTM A240). Seals are EPDM, FDA compliant. These materials ensure corrosion resistance and food safety.

How does the homogenizer contribute to sterilization?

The high-pressure mechanical shearing disrupts microbial cells, which aids in microbial reduction. However, it is not a substitute for UHT treatment; it operates before final UHT to enhance overall effectiveness.

What is the typical flow capacity?

The flow capacity ranges from 5000 to 20000 L/h, depending on line throughput. Select the appropriate capacity based on your production requirements and verify with the supplier.
