Brief Introduction
The tunnel pasteurizer is an especially designed pasteurization device for dairy, fruit juice, beverages, beer, food and medicinal products, to be used after products have been filled or packaged into containers. This is the ideal device for materials to undergo sterilization, temperature control and cooling for extending the product’s shelf life.
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.
