Fruit pomace is the residue produced during fruit processing, usually referring to the solid part left after juicing, making sauce or drying. Fruit pomace contains not only the fiber of the fruit, but also some nutrients.However, raw pomace often contains high moisture content, making drying an essential step in its processing. Here, the pomace dryer plays a pivotal role by enhancing the quality and usability of pomace for various applications.
Importance of Pomace Drying
Extend shelf life: Drying can remove moisture from pomace, prevent bacteria and mold growth, and thus extend its shelf life.
Reduce waste: Drying pomace can effectively utilize the residues generated during processing, reduce food waste, and promote the recycling of resources.
Increase nutrient concentration: Dried pomace retains many nutrients, which is convenient for making healthy foods and supplements, and improving the overall nutritional value.
Easy to store and transport: Dried pomace is small in size and light in weight, easy to store and transport, and suitable for long-distance transportation and retail.
Diversified applications: Dried pomace can be used as a raw material for a variety of products such as baking, beverages and feed, which broadens its use.
In short, pomace drying not only helps the effective use of resources, but also brings multiple benefits to the food industry and consumers.
How Pomace Dryers Work
Materials are uniformly put on the mesh-belt by the feeder. The mesh-belt uses generally 12-60 mesh stainless steel wire net and it is drawn and moved inside the drier by a transmission device. The drier is composed of several units. For each unit, the hot air is circulated separately. Some exhausted gas is discharged with a special moisture elimination blower. The waste gas is controlled through an adjustment valve. The hot air passes through the mesh-belt covered with the material from the top to the bottom or from the bottom to the top and this will complete the heat and mass transfer process. This process will bring the material water away. The mesh-belt moves slowly, running speed can be freely adjusted according to the material temperature. The final products after drying will fall into the material collector continuously. The top and low circulation units can be freely equipped according to the users’ demand. The unit number can be selected according to the demand.
DW series multi-layer belt dryer is a continuous drying equipment for batch production. It is suitable for large-scale production of difficult-to-dry materials with low drying rate. The equipment has compact structure, small floor area, simple operation, convenient maintenance and stable operation.
