Belt drying machine

Extensions and options

Material supply
Each module has an upper cover, which is performed in the same manner as the side panels. They have an outlet for the evacuation of hot air. Between the stacked modules are built, no additional separation. Only the external module is provided with a funnel. For the feeder conveyor to the hopper can be offered in the form of elevators, screw conveyors or belts.
Host material
Under the overall construction, a host is attached. Different recovery techniques can be selected (screw, chain, tape). At the end of the dryer, the material can then be removed and transported further. For this also we can offer various recovery techniques.
Exhaust (optional)
On the hot-air outlet for an extraction system can be connected with a centrifugal separator. As the warm air escaping up always carrying dust and fine material, this is recommended in enclosed spaces. When using a heat recovery, this is even mandatory.
Heat recovery (optional)
When using a heat recovery of hot air through the aforementioned suction of air dehumidification is supplied. The dried air is recirculated into the system and the condensation of water deposited. This air has the advantage that it is even more receptive to moisture, and thus speeds up the drying process.
Materialmixing (optional)
For very fine material, it can be advantageous to reallocate that during the drying process. Fees may be attached if necessary, through the bands mixer, which run along on the drive of the belts.
Heatsystem (optional)
The infrared emitters are by default in the execution 400W. It can also spotlight up to be fitted to a thickness of 1200W. Should not both be sufficient heating systems can be installed as an option stainless steel heaters . These are available in the performance strengths 500-2500 watt.
Service bays (optional)
For larger concepts, it is better  bring in between each drying modules in the horizontal service bays. This helps you of maintenance, cleaning and repair work.

Modular concept

The modular design is tailored to an individual realization of the problem possible. This maximum of 6 modules and 10 modules can be stacked in series. This means a conveyor line 2 to 120 meters. Also there is the possibility to increase retroactively the facility, but only in height.

Throughput

Regarding the planning of the system size, then have a lot of factors. These are primarily the quantity of material to be dried, its texture, initial moisture and desired residual moisture. In order to design the size of the facility, must be carried out a material test. It is necessary to determine the behavior of the material during the drying process. It is necessary to determine at what time a certain amount of material available and at what temperature the desired humidity is reached (input and output moisture). With this information, the size of the plant can then be calculated.. It is necessary to deviate from the standard in order to implement the requirements.

Basic Structure

Promotion
A module consists of a conveyor belt of 2 meters in length. This can be supplied in widths of 30cm, 50cm and 80cm. As the material available here, depending on the requirements of stainless steel or galvanized steel are available. The tapes consist of a very fine wire mesh, which has a high stability and yet is highly breathable to ensure optimal material penetration. The tapes are held with the side chains and are driven by gears. Both are made of burnished steel. In addition, the tapes kept stable by the horizontal support roles in order to resist high loads.
Frame construction and insulation
The overall total is kept in a galvanized steel finished frame construction, which is laterally provided with a powerful 85mm mineral wool insulation. The side panels are designed for maintenance cleaning and repair work designed to take off. This also allows easy expansion and implementation of the modular concept.
Heating Systems
2 heating systems are supplied as standard. Firstly, the construction is crisscrossed with steel tubes, passed through the hot water or steam can be. In addition, all modules have 8 or 12 infrared emitters (, have their own temperature control device that is adjustable up to 180 degrees. Temperature sensors thereby regulate the set temperature. An indicator of the prevailing temperature in the interior is also available.
Drive
It is controlled by a geared motor with infinitely variable regulation. It can be belt speeds from 0.16 to 0.8 m / min / set. For an example dryer belt length of 12 meters, this would lead times between 15 - 75min.

Belt Dryer

The processing of biomass for fuel (pelleting, briquetting, etc.) requires the preparation of the raw material. Key factors are the particle size and moisture content.

To adjust the moisture content, it is often necessary to dry the material. It is advisable, where feasible and economically viable, the gross mass of a minimum content of 8% to 12 % moisture and then adjust by adding moisture.

Belt dryers are interesting because they usually the easiest and most effective drying and can be used also for the entire spectrum of the biomass. Even with high moisture biomass can therefore be dried. For this reason we chose this option and offer this to a modular system, based on a drying surface between 0.6 meters (2m x 0.3m) and 96m ? (120m special x 0.8 m) and thus can be extended as the application requirements can be adjusted.

The following features and specifications of our band dryer:
