柑橘类水果加工
果汁生产的成功一方面取决于外观、口味和质地之间的重要平衡，另一方面又取决于健康安全因素和生产成本。阿法拉伐的设备、系统和服务能够帮助客户实现这种平衡，而这尤其体现在柑橘加工厂的运营中。
橙子的分离、浓缩和杀菌
如果您从事橙汁生产，Foodec沉降式离心机就是您的理想之选，它能够在提取结束后去除果肉，此外，各种类型和尺寸的阿法拉伐碟式离心机也广泛应用于浊汁的澄清或果肉回收。
密封式分离
柠檬加工得到的果汁中的柑橘油含量往往较高。在不影响果汁品质的情况下降低这种油含量的最佳途径是采用离心分离法。这是一个极其精细的操作，因为油量是十分微小的。
阿法拉伐密封式分离器借助其密封碗的超顺畅动作，能够有效且可靠地去除这种油。
橙子杀菌
结构紧凑且热效率高的阿法拉伐换热器技术还广泛用于确保在温度调节时对NFC果汁（即便果肉含量较高）进行尽可能的柔和处理。这些阿法拉伐设备还用于进行巴氏杀菌，从而灭活果汁中存在的所有酶，确保微生物稳定。
芳香和油回收
在进行橙汁加工的同时，还可从柑橘中提取高价值的油和芳香。阿法拉伐也可为您提供先进的油回收设备，用于将细腻的油乳剂加工成澄清的纯果皮油。
Oranges
Oranges are cultivated in tropical and subtropical regions throughout the world. About 60 million tonnes of oranges are grown annually, accounting for more than two thirds of the world production of all citrus fruit. Of this, about 40% are processed into juice and the rest consumed as whole fruit.
Focus on concentrate
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 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.
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.
