The process begins with the careful receiving and inspection of raw fruits. This involves quality control checks to ensure only the finest produce enters the line. Following this, a thorough washing system removes dirt, debris, and pesticides, using high-pressure water jets and possibly specialized brushes. This step is critical for maintaining hygiene and food safety throughout the production process.
Efficient fruit handling and sorting systems, often incorporating conveyor belts and optical sorters, are essential to optimize throughput and minimize manual labor. These systems can identify and remove damaged or substandard fruits, ensuring only top-quality ingredients are processed.
After washing, fruits are processed for juice extraction. This might involve different techniques depending on the fruit type, ranging from simple pressing for softer fruits to more complex methods like enzymatic treatment for higher yields from tougher fruits. The type of juicer used—whether it's a hammer mill, screw press, or a combination—significantly impacts efficiency and juice quality.
The extracted juice often requires clarification to remove pulp and other solids. This can involve techniques like centrifugation or filtration, resulting in a clearer and more appealing final product. The level of clarification depends on the desired juice style, from cloudy to clear.
To ensure shelf stability and safety, the juice undergoes pasteurization. This heat treatment eliminates harmful bacteria and extends the product's shelf life. High-temperature, short-time (HTST) pasteurization is commonly employed to minimize the impact on the juice's flavor and nutritional value.
Finally, the pasteurized juice is packaged into various containers, such as cartons, bottles, or pouches. Automated filling and sealing machines are essential for high-volume production, ensuring speed, consistency, and hygiene. Efficient packaging also plays a vital role in preserving the product’s quality and extending its shelf life.
