When it comes to drying granular materials, a belt dryer is the most efficient option. The vertical configuration of the bottom outlet allows the material to be discharged directly or indirectly, depending on the material. The advantages and disadvantages of belt dryers are dependent on the application.
Here’s a quick look at the advantages and disadvantages of this type of drying. Its benefits include higher capacity, shorter drying times, and high flexibility.
A belt dryer is a continuous device that can dry moulded compounds, woodchip, and panels. Despite their many benefits, belt dryers have disadvantages.
They require frequent lubrication and cleaning, and they require a confined space to work in.
Their design makes it difficult to work inside, and they can also be hazardous, requiring a qualified electrician to inspect their inner mechanisms.
However, the advantages are outweighed by the disadvantages.

The main disadvantage of belt dryers is their large size, and they are not suitable for small spaces. For larger applications, it is advisable to use a multi-pass dryer.
These dryers are often designed in modular fashion and may have more than one conveyor belt.
The advantage of multi-pass dryers is that they can be customized to accommodate multiple products.
The advantage of using a single conveyor belt for drying vegetables is that they do not require ventilation and can be used in any temperature.
A belt dryer’s advantages are many. Its main disadvantage is that it requires continuous feeding, which is necessary to maintain product quality.
It isn’t suitable for whole plants, and it may lead to breakage or stretch of the material.
It is not recommended for a continuous process, but it is an excellent choice for batch drying. A horizontal dryer has other benefits, regardless of its operation.
A continuous operation allows the material to flow continuously through the vessel, while a batch operation allows the material to pass through the device continuously.

Another disadvantage of a belt dryer is its small working volume. This means that it isn’t suitable for very large drying jobs.
Its limited working volume means that it’s not appropriate for heavy-duty applications.
It can be used for dry raw materials in stages. A static dryer is an ideal option for small-scale producers.
Its low-level ground area demands are advantageous.
A static dryer is highly flexible. In addition, it can be customized to suit different applications.
The main disadvantage of a belt dryer is its slow speed. Its speed is relatively slow.
Because of this, a belt dryer has a high energy consumption.
Compared to a traditional dryer, a belt dryer is more efficient when it comes to drying smaller materials.
In contrast to the conventional dryer, a vertical dryer is more expensive.
It is also a more complicated process. But if your needs are small, a vertical dryer is a better choice.

In addition to being slower than a belt dryer, this equipment is expensive.
The rotor must be properly aligned to avoid the bow wave. Otherwise, the material will not flow smoothly across the bed.
This means it is not suitable for drying materials in bulk quantities.
Besides, the downside of a vertical dryer is that it’s less versatile than a rotary dryer. Its drawbacks are also difficult to adjust.
Another disadvantage is that it is not always easy to install. It requires an extra-large space.
A vertical dryer’s size can be limited by a large screw feeder.
Moreover, the screw feeder feeds the cloud with water and waste product.
Unlike a conventional dryer, a vertical dryer’s speed is limited by the heating system, but it is still more efficient than a manual dryer. But it is still not perfect.

In addition to its inefficiency, a belt dryer isn’t very effective when it comes to processing different types of materials.
The latter is less productive than a belt dryer, so it’s more likely to cause problems.
Moreover, it doesn’t handle the same type of products. Furthermore, it has fewer disadvantages compared to its advantages. Its operating time is flexible.
Its low throughput makes it a good choice for medium-sized farms with low throughputs.
