Industrial dryers diffusion process explained in mockup

Industrial dryers are used in many industries for their production processes. The costs of these can be considerable, taking their size and life cycle into account. A good industrial dryer can last many years, even decades. That is why it is so important to choose a device, which will answer to your needs and fill the gaps in your production process.

A wrong choice can result in adverse effects for your company’s financial situation and reputation as regards the quality of results. The many different chioces available on the market can make deciding more difficult, which is why we have compiled a list of important qualities to look for in any industrial dryer before making the final choice. Read on to find out, what is crucial for you.

  • You definitely need to test the industrial dryer before buying it, by proofing its effect on the test material. This is vital to determine the possible results it can have for your productivity and the final product.
  • You should always bear in mind the size of the testing material before the start of the drying process and the density that the material should have the process will have been finished. The method and type of the dryer will depend on those. If you are having difficulties to determine the exact sizes, consult an expert.
  • Moisture level. Any material that you wish to dry will have a specific level of moisture. It is very important to know the level or percentage of moisture at the start of the process and well as the desired finished percentage. During the testing process, these levels will be set very specifically, which will help to determine the right dryer type.

There are definitely more factors which influence the quality of the drying process and the choice of the right dryer. Let us now have a look at the different dryer types, which you can choose from.



A continuous dryer can lower your energy costs

A continuous dryer requires to be managed very precisely, demanding a constant supply. This is the reason why it is often advised for larger farms. There, bigger volumes of cereals have to be dried and this quantity of grain is fed into the continuous dryer at constant speed, without any interruptions. Smaller ventures might have problems supplying the machine with enough grain to keep in constantly running.

Yet, you can pool with your partners to allow for a bigger constant flow. It is important to note that in case of a big continuous dryer, considerable quantities of heat will be produced. This heat can be recuperated and reused, thus considerably reducing your energy costs. What is more, the noise level, which might be reasonably high in case of some large industrial dryers, can be lowered by installing a buffer ventilation system.

A chamber dryer is ideal for quick drying

Another type of industrial dryers is a chamber dryer. As the name suggests, several chambers make it up, which are mutually connected, but separated by sliding doors. The complexity of a chamber dryer is added by the structure of shells and shafts, guaranteeing the smooth operation and easy maintenance. In a chamber dryer, the material is dried for a calculated period of time.

The time spent in each chamber is supervised by the system, which – after its expiration – ejects the material from the former into the next chamber. This is complemented by hot air rotating in the system for added efficiency. The complete amount of time spent in the dryer is usually around five minutes.

A rotary dryer works by employing a tumbling drum

A rotary dryer is another type with its own specific characteristics. Usually used for drying bulk material, this type of dryer is known for being robust and durable. They operate by rotating or tumbling, employing a drum, though which hot air is circulated. If a danger exists that the material could inflate, the direct contact between the drying material and the hot air can be avoided. Upon rotation, the material is lifted and turned for a better air circulation and faster drying.
