A hot-fill juice filling machine is designed for the production of shelf-stable juices that can be stored at ambient temperature. This process involves heating the juice to pasteurization temperatures (typically between 85°C and 96°C) to destroy spoilage microorganisms and enzymes, holding it at that temperature for a specified time, and then filling it hot into heat-resistant containers (typically PET with heat-set panels or glass). The machinery is constructed to withstand these high temperatures, featuring insulated product tanks and pathways, and cooling systems to protect mechanical components. Immediately after filling and capping, the bottles are inverted or passed through a tunnel pasteurizer to sterilize the cap and bottle headspace with the residual heat. They are then cooled in a water spray cooler. This cooling phase causes the liquid and headspace to contract, creating a vacuum inside the bottle that acts as a preservative and prevents recontamination. Ace-Filling's hot-fill systems are integrated solutions that manage this entire thermal process, ensuring the production of safe, shelf-stable juice products with a long ambient shelf life, which is ideal for high-acid juices like apple, orange, and berry blends.
