Transformation des agrumes
La réussite de la production de jus de fruits dépend d'un équilibre optimal entre l'apparence, le goût, la texture et la sécurité sanitaire d'une part, et les coûts de fabrication d'autre part. Les équipements, systèmes et services proposés par Alfa Laval permettent à ses clients d'atteindre cet équilibre.
Séparation, concentration et pasteurisation des oranges
Si vous produisez du jus d'orange, les décanteurs centrifuges Foodec sont la solution idéale pour retirer la pulpe après l'extraction, tandis que différents types et tailles de séparateurs centrifuges à assiettes Alfa Laval sont communément utilisés pour la clarification et la récupération de la pulpe dans les jus troubles.
Séparation hermétique
La transformation des citrons en jus entraîne souvent des niveaux élevés d'huile de citron dans le jus. La meilleure façon de réduire ces niveaux d'huile sans mettre en péril la qualité du jus est la séparation centrifuge. Il s'agit d'une opération extrêmement délicate car les quantités d'huile sont minimes.
Les séparateurs hermétiques Alfa Laval sont capables de retirer cette huile de façon efficace et fiable grâce à une action ultra douce du bol hermétique.
Pasteurisation des oranges
La technologie des échangeurs de chaleur Alfa Laval compacte et à haut rendement thermique est également largement utilisée pour assurer la transformation la plus douce possible des jus NFC (même avec une teneur élevée en pulpe) lorsqu'on ajuste les températures. Ces systèmes Alfa Laval servent aussi à la pasteurisation qui désactive toute enzyme présente dans le jus et lui apporte sa stabilité microbiologique.
Récupération des arômes et huiles
On peut aussi extraire de précieux arômes et huiles des oranges en association avec la transformation du jus. Alfa Laval peut également fournir des systèmes de récupération d'huile dernier cri capables de transformer des émulsions d'huile délicates en une huile essentielle pure et claire.
Scalable orange processing for global juice markets
Commercial orange processing focuses on two core outputs: premium juice and peel oil. Rapid, low-temperature concentration using rising-film technology preserves flavor and supports aroma recovery, while fruit juice extraction equipment and modern separators ensure stable pulp levels and clarity. These integrated technologies streamline the entire workflow, from extraction to pasteurization of oranges, delivering predictable, high-yield performance.
Focus on concentration
There are normally two focal points in the commercial processing of oranges – the juice itself and the oil extracted from the peel.
The juice is normally processed into concentrate or high-quality NFC (Not From Concentrate) juice, which can usually be sold at a premium. NFC-based juice is currently in considerable demand worldwide and is the fastest-growing market segment for orange juice.
When the juice is produced as a concentrate, equipment such as AlfaVap rising-film evaporators ensures rapid, low-temperature concentration. With the addition of a special aroma recovery unit, this gentle treatment helps make sure you get juice of the best quality.
Separation, concentration, and pasteurization of oranges.
Alfa Laval is a world leader in applying advanced centrifugal separation technologies to food and beverage processing.
If you produce orange juice, Foodec decanter centrifuges are ideal for removing pulp after extraction, while different types and sizes of Alfa Laval disc stack centrifuges are widely used in clarification.
Compact, thermally efficient Alfa Laval heat exchanger technology is also widely used to ensure the gentlest possible treatment when adjusting temperatures, and also for pasteurization that deactivates any enzymes present in the juice and makes it microbiologically stable.
Aroma and oil recovery
High-value oil and aromas can also be extracted from oranges, side by side with juice processing.
Alfa Laval can also supply you with state-of-the-art oil recovery units that can process delicate oil emulsions into clear, pure peel oil.
Optimized lemon processing for juice and high-value oils
Lemons differ from other citrus fruits because their juice is too acidic for direct consumption, making processing essential. The juice is typically concentrated to 48–55 °Bx or used as a stable ingredient in beverages and formulations. The oil extracted from lemon peel carries significant commercial value, driving the need for precise separation and consistent thermal management.
Whether operating single-fruit or multi-fruit facilities, processors benefit from systems designed to maximize yield and maintain product integrity. Effective peel-oil separation is central to citrus processing, and hermetic bowl technology ensures reliable removal of trace oils without compromising flavor or clarity. These capabilities support diversified revenue streams across global citrus markets.
Lemons
Lemons are mainly grown for the special culinary properties of the highly acid juice and also for the oil extracted from the peel. This fetches a very high price, and is therefore much in focus when processing lemons.
The many kinds of juice that can be extracted from citrus fruit are normally destined either for domestic consumption or for processing into concentrate or high-quality NFC juice. This is not the case for lemon juice, however, because this juice is too acid to drink.
The juice is normally either concentrated to approx. 48–55 °Bx by evaporation or – less commonly – sold as single-strength juice. This juice can also be used as an ingredient in many other beverages, as it is known for its stable qualities.
Versatile revenue maximization
Regardless of whether you run a single-fruit processing operation or a multi-fruit installation, Alfa Laval systems and equipment can help you achieve quality levels that strengthen your revenues from lemon products.
The oils side
In citrus fruit processing, Alfa Laval is also renowned for equipment that separates oil from the peel. During this process, it is important to safeguard quality via the effective thermal management available from market-leader Alfa Laval equipment.
Hermetic separation
Processing lemons into juice often results in high levels of citrus oil in the juice.
The best way to reduce such oil levels without jeopardizing the quality of the juice is by centrifugation. This is an extremely delicate operation, because the amounts of oil are minute. Alfa Laval hermetic separators are able to remove this oil effectively and reliably due to the ultra-smooth action of the hermetic bowl.
