Juice to Powder - Our dryers are designed to fulfill the very strict quality requirements demanded by the food industry.

These are products made from natural ingredients. It is desirable to retain as many of the natural properties and qualities in the final powder as possible. This can be done for some products, but for others a recipe must be made containing additional carriers, antioxidants, pH-stabilizers and so forth.

JUICE:
Juice is a quality name and can only be used to describe a reconstituted powder if the powder contains a maximum of 3% additives, such as sucrose on solid base. Real juice powder is made when a high concentration of natural fibres remains in the juice. This has only been possible for a few juices. The dryer for these powders is the FILTERMAT®.

Several juices has been dried to a powder as a flavour product where the concentrated juices or single strength juices are mixed into a flavour base made from e.g. maltodextrin, sugar and gum arabic. The reconstituted powders with this recipe are not real 'juices'. These powders can often be dried on conventional spray dryers, multistage dryers, or the FILTERMAT®.



FRUIT:
The pulp or paste from many fruits and berries are strained to be freed from skin, seeds and long fibres to create a paste which can be spray dried in this pure state, or with only a limited addition of carrier.

Many of these powders will give reconstituted products very close to the original paste in respect to retaining the natural properties like colour, flavour, taste and texture. The FILTERMAT® will be the most attractive dryer for production of high-quality powders from these fruit and berry pastes.


TOMATO:
This is a special fruit which is spray dried in large amounts from a concentrated paste. The powder is made from Hot Break paste or Cold Break paste. The paste used is strained free of skin, seeds and long fibres, and is concentrated to a maximum of 45 °Brix for Hot Break and 50 °Brix for Cold Break. Niro has developed a special tomato spray dryer, which is the most used tomato dryer worldwide. We have also developed the technology for the drying of tomato paste on the FILTERMAT®. The tomato powder can be made without the used of any additives on the Niro dryers.


VEGETABLES:
Vegetables can be spray dried when they exist as juice or a paste, as described above. The amount of carrier used for the juices will normally be less than for the fruit juices, due to vegetable juice composition. The filtered and concentrated juices are normally dried as flavours, and are mostly dried on conventional dryers and multistage dryers.

The pastes which are strained free of skin and long fibres will normally be concentrated, and yield very good products when dried on the FILTERMAT® dryer. These products can normally be dried without additives, typically resulting in high-quality products which can compete easily with freeze dried powders.


MARKET:
Niro has experience with spray drying juices and paste from a very large range of fruits, berries and vegetables. We are the single largest supplier of tomato dryers and FILTERMAT® dryers.

The capacity ranges between 50 - 800 kg final powder per hour, depending on product.

Our dryers are designed to fulfill the very strict quality requirements demanded by the food industry, and can even be delivered as validated installations.
