Industrial grader separates seeds and dust from frozen juice product at fruit juice production plant
Now, more than ever, sustainability and waste reduction have become concerns for many manufacturing companies. Eco Treasures recognise that natural resources should be used in a sustainable and economical way.
In 2006 this Belgium-based company set up a pilot installation especially designed to utilise processing activities aimed at reusing or recycling product back into the production process. One of Eco Treasures’ main production activities is the ecological extraction of essential oils from residual vegetable feedstock and fine fruit seeds.
The seed oils, such as raspberry and pomegranate, are those with the most organic forms of rich, unsaturated fatty acids and vitamins and are mainly supplied to the food and cosmetics industries.
Since the introduction of the Eco Treasures pilot plant, the company has been constantly looking for ways to enhance its manufacturing process. Having previously used a very simple sieving process, delivering consistency of product quality was proving difficult.
To meet high-quality standards, and ensure the best production efficiency, the company trialled a vibratory grading machine at their pilot plant.
The extraction of seed oil from residual frozen pulp begins by separating the seeds from the juice pulp. To separate the seeds, the frozen pulp is first melted and then dried. Once separated the seeds then go into a press to extract the oil.
The issue the company was facing was that there was too much dust from the dried juice pulp attached to the seeds after the drying process, which resulted in a lower quality of extracted oil. Therefore, the company decided to separate the product into two fractions (fine dust and seeds) before the seeds were passed to the press. With the Russell Eco Separator® Eco Treasures could separate the two fractions enabling them to send the seeds through the press free of dust.
Not only did this gyratory food sifter eliminate the dust from the seeds, it also saved them time by reducing the amount of labour previously involved in manually sieving the product. These two factors contributed to the reduction in manufacturing costs for Eco Treasures, an increase in productivity, as well as improved product quality for their customers.
Production Manager at Eco Treasures, Stefan Ongena, said:
“We were able to run tests with the Russell Eco Separator both at our site and at the Russell Finex test facility. As a company with a pilot production plant it was very useful to benefit from Russell Finex’s experience in sieving. They were willing to think ahead with us and offered us the solution we needed.”
