Brief Introduction

Tunnel Pasteurizer machine is designed and manufactured on the basis of European advanced technology and combined with domestic and foreign market conditions. The capacity of technology and the quality of the product are on the leading level, It is not only suitable for pasteurizing 300-1000ml canning Carbonated drinks, but also fits for any kind of packaging object such as the PET bottle, jars .,etc with height less than 340mm.

Product Features

1. Multi-step process of pre-cool with cycled warm water, spout and sterilize with cycled hot water, cool with cycled cooling water, etc. has performance of water saving, heat saving. Adopting 8~12 temperature zone design can use energy-efficient centralized heat exchanging.

2. Overcurrent protection and overload protection can avoid damaging device due to overload.

3. Less temperature gradient not only guarantees good sterilizing effect, but also decreases broken bottle rate. Temperature zone is square pipe square hole spouting, not only guaranteeing temperature demand but also not easy blocking, and adopt fast-disassembling plug-in type, which is convenient for cleaning and maintenance of water pipe.

4. When bottle discharge conveyor is blocked, speed reducer automatically stops. If stop time is too long, water temperature of high temperature zone and heat preservation zone automatically descends 58℃ below to avoid PU value of beer rising too high due to too long stop time.

Frequently Asked Questions

What information is needed to configure the Tunnel Pasteurizer?

Please provide the beverage recipe, process flow, inlet and outlet conditions, required throughput, cleaning requirements, utilities and plant layout. HZM uses these inputs to define tanks, heat treatment, mixing, piping and controls.

How is the process configuration selected?

Product composition, viscosity, temperature, treatment time, hygiene target and downstream filling conditions determine the equipment and control strategy. The final process must be confirmed against the approved recipe and product standard.

Can the system handle different beverage recipes?

Multiple recipes may be supported through suitable tanks, controls and cleaning procedures. Ingredients, thermal sensitivity, allergens, particles and required changeover cleaning must be reviewed for each product.

Can this equipment be integrated into a complete production line?

Yes. HZM can coordinate upstream processing or bottle making with filling, labeling, coding, packaging, conveying and palletizing. Layout, utilities, controls, factory testing, installation, commissioning and training are defined by the agreed project scope.
