What are the steps in the pineapple processing process in the industry? As a representative of tropical fruits, pineapple processing efficiency and quality control have become the core competitiveness of food companies.
Industrial production lines can not only greatly increase production capacity through automated and standardized process design, but also ensure that products meet international food safety standards.
This article will deeply analyze the core steps of pineapple processing and explore how special machinery can help companies achieve cost reduction and efficiency improvement.
Industrial production lines are usually equipped with high-precision optical sorting machines, which use AI visual systems to quickly identify the maturity, size and skin damage of fruits and automatically remove unqualified products.
Industrial production lines use a multi-stage spray system combined with high-pressure water jet technology to completely remove mud and microorganisms on the surface of the peel.
Modern models use laser positioning and robotic arm collaborative technology to accurately remove the peel and the coarse and hard fiber core, with a pulp utilization rate of more than 92%.
Before entering the freezing stage, the slices must pass through a metal detector and an X-ray foreign body screening system.
Advanced color sorters can automatically grade the pulp according to its color and separate products of different maturity.
Industrial-grade spiral quick freezers can reduce the center temperature of the fruit slices to -18°C within 12-15 minutes at -35°C, and quickly pass through the ice crystal formation zone to reduce cell damage.
Some production lines also integrate vacuum pre-cooling technology, which can discharge the internal heat of the pulp in advance, increasing the quick freezing efficiency by more than 30%.
The fully automatic weighing and filling machine can complete the packaging according to the set specifications (such as 1kg/bag or 10kg/box), and fill with nitrogen mixed gas to extend the shelf life.
From raw materials to finished products, the steps in the pineapple processing process are inseparable from the coordinated operation of precision equipment.
