Gooseberry (Amla) Juice Extraction Using Dewatering Screw Press

Gooseberry, commonly known as Amla, is widely celebrated in Indian traditional medicine and nutrition for its high Vitamin C content and potent antioxidant properties. Its juice is a key component in health supplements, Ayurvedic formulations, and modern wellness beverages. However, the tough fibrous texture and presence of hard seeds often pose challenges in large-scale juice extraction.

Nature of the Material

Amla is a firm, fibrous fruit with a hard inner seed and a high moisture content. The juice is rich in nutrients but locked within dense fibers, making mechanical separation critical for efficient extraction. Additionally, the seed needs to be managed without causing operational issues.

Extraction Trial and Setup

To validate the performance of our Dewatering Screw Press for Amla processing, a series of trials were conducted using both shredded and unshredded gooseberries. The trials were carried out on a 4-inch screw press equipped with a 1 mm perforated screen.

Both forms of Amla—shredded and whole—were processed smoothly. Although slightly better results were obtained with shredded Amla in terms of juice clarity and flow, the difference was minimal, and the equipment handled unshredded whole fruit effectively, showcasing the press’s adaptability.

The hard seeds passed through the screw press without damaging the machine, demonstrating that the design can accommodate the tough inner core without creating bottlenecks or wear-and-tear on the system.

Performance and Results

  • Juice Yield: 70–75% by weight
  • Juice Quality: Rich in nutrients, minimal pulp, easily clarified
  • Screen Used: 1 mm perforation (customizable as per clarity requirements)
  • Seed Handling: No clogging or resistance; seeds passed through effortlessly

The juice collected had minimal suspended solids, and any fine pulp that remained was viewed by clients as a valuable co-product.

Post-Processing and Filtration Options

For applications where a clear juice is preferred, a secondary filtration system can be integrated post-pressing. Depending on the desired clarity level, options include:

  • Inline mesh strainers
  • Vibratory screen separators
  • Bag filters or cartridge filters
  • Decanter centrifuges for high-throughput separation
  • Membrane filtration systems for premium clarity

These options allow processors to tailor their system to achieve the exact level of juice clarity needed for bottled drinks, wellness shots, or nutraceutical applications.

Applications

  • Ayurvedic and herbal health formulations
  • Immunity-boosting beverages and wellness shots
  • Vitamin C supplements
  • Ingredient in hair and skincare formulations

The Dewatering Screw Press provides an effective, continuous, and high-yield method of extracting juice from Gooseberries. With its ability to handle both whole and shredded fruits, tolerance for hard seeds, robust juice yield, and flexible downstream filtration, it proves to be an ideal solution for producers looking to process Amla efficiently and sustainably.
