Mesh belt is drawn and moved inside the dryer by a driving device. The dryer is consisted of several independent drying sections. Hot air circulated separately and independently in each section. Part of damp air will be exhausted by exhausting fan. Hot air penetrates the belt from top to bottom or from bottom to top, and this will complete the heat and mass transfer process. Moving speed of belt is adjustable. The top and bottom circulation units can be freely equipped according to customer's requirement.
◆◆ Length , width and layer quantity of belt is designed based on production requirement.
◆◆ The machine pre-dehydration process could remove massive moisture on leaf surface, thus reduced the drying strength, and reduced the energy consumption.
◆◆ Special hot air drying system, increase material penetrability and drying rate.
◆◆ The adjustment of belt speed and the different section temperature control, it guaranteed the drying time and material quality and color.
◆◆ Strong magnetism iron removal device is available for choice, it could remove metal impurities effectively.
drying the piece, strip and particle shape materials in good ventilation. The dryer is suitable for de-watering fruit & vegetable which the moisture content is high and high drying temperature is not allowed. Drying speed of belt dryer is fast, evaporation strength is high and the product quality is good.
◆DWF belt dryer is widely used and support for drying various kind of material such as pigment, fiber, fruit & vegetable, briquette etc.
1) Wide applications: The residence/drying time is adjustable from 15 minutes to 120minutes which makes it flexible to dry various kinds of raw material. 2) Energy-saving: Different types of hot air flow pattern and well insulated drying chamber can considerably reduce heat loss. Hot air circulation can be designed for energy-saving.
3) Uniform drying: The specially designed hot air distributor and drying zones can make sure uniform air flow in side the whole drying chamber to guarantee uniform drying.
4) Easy operation and maintenance: The whole drying system is highly automatic. The simple but practical design can not only reduce production cost but also maintenance and repair cost.
5) Flexible heat source: The heat source for drying can steam, electricity, hot water, thermal oil or oil/gas/coal/biomass fired hot air generator. We can design and engineer different heat source according to customer's actual conditions.
6) Different types and layers of mesh belt are vailable based on specific raw material and drying conditions.
