Product Overview
Designed for hot-fill production processes, this equipment works in coordination with hot filling machines. It makes full use of the heat of freshly filled high-temperature liquid products. Through automatic bottle inversion during conveying, the hot liquid fully contacts the inner sealing surface of bottle caps and bottle mouth threads, realizing pasteurization on these positions and effectively killing residual microorganisms to guarantee product shelf life.
The whole machine adopts food-grade stainless steel construction with smooth and reliable conveying performance. It automatically completes the whole process of upright feeding, steady inversion, heat-preserved conveying and upright resetting, and can be directly connected with upstream filling lines and downstream cooling equipment. It is essential supporting equipment for hot-fill beverage production lines.
Equipment Features
- Energy-saving operation with residual heat utilization It realizes sterilization by fully utilizing the high-temperature residual heat of filled liquid products, without any additional heating source. It has extremely low energy consumption and low long-term operation cost.
- Fully automatic continuous operation It automatically completes the whole process including upright bottle feeding, steady inversion, heat-preserved conveying and automatic upright resetting, without manual intervention. It can be seamlessly connected with upstream and downstream production lines to realize continuous production.
- Stable conveying without bottle jamming Adopting dedicated chain plate conveying structure and guiding mechanism, it ensures smooth and reliable bottle inversion process, free from bottle tipping, jamming or falling, with stable operation and low failure rate.
- Food-grade hygienic construction The whole machine is fabricated with food-grade stainless steel, with smooth surface and simple structure for easy cleaning, fully complying with hygiene standards of food and beverage production.
- Wide compatibility with various bottle types It is compatible with PET bottles and plastic bottles of various specifications and capacities, with convenient adjustment and strong adaptability to different product requirements.
- Modular design for flexible layout Modular integrated structure allows customized length according to production capacity and sterilization time requirements. It features flexible installation and layout as well as simple daily maintenance.
Working Principle
The equipment is connected to the hot-fill production line. Bottled products that have just finished hot filling and capping enter the machine in upright position.
Driven by the conveying chain plate and guided by the guiding mechanism, bottles are automatically and smoothly inverted. At this time, the high-temperature liquid inside the bottle fully contacts the inner sealing surface of the cap and the bottle mouth threads, performing pasteurization on these areas by the heat of the liquid itself, and killing microorganisms that may remain during filling and capping.
After passing through the inversion conveying section for the preset sterilization holding time, bottles are automatically flipped back to upright position at the outlet, and then conveyed to the subsequent cooling process. The whole process runs continuously and automatically, with stable and reliable sterilization effect.
