Explanation And Application Of Multi-layer Dryer
A multi-layer dryer is a drying equipment that uses a mesh belt as a conveyor belt to transport materials for continuous drying, suitable for assembly line operations. Due to the fact that the conveyor belt is a mesh belt, it can dry various block shaped objects (such as food, vegetables, etc.) with regular or irregular drying rules. Multi layer dryer can be used in conjunction with other equipment. It can also be used separately. Multi layer dryer equipment can be widely used in many industries, and it is also an ideal equipment for drying and processing food and vegetables, especially suitable for drying sheet, strip, and granular materials with good breathability. It can also be used for drying and drying the surface moisture of soft packaged food.
Multi layer belt dryer, flip plate dryer, stainless steel mesh belt dryer, and belt dryer are drying equipment for batch and continuous production. The main heating methods include coal-fired heating, electric heating, steam heating, and hot air heating. The main principle is to evenly spread the materials on the conveyor chain plate, using a mesh belt with a diameter of 3mm-8mm, which is dragged back and forth in the dryer by a transmission device. Hot air flows through the materials, and water vapor is discharged from the dehumidification holes to achieve the purpose of drying. The length of the box is composed of standard sections. In order to save space, the drying mechanism can be divided into multiple layers, commonly 3 and 5 layers The dryer consists of several units, with each unit having independent hot air circulation. Some of the exhaust gas is discharged by a dedicated dehumidification fan, and each unit has a regulating valve to control the exhaust gas. The hot air passes through the chain plate covered with materials from top to bottom or from bottom to top to complete the process of heat and mass transfer, taking away the moisture of the materials. The mesh belt moves slowly, and the running speed can be freely adjusted according to the material temperature. The dried finished product continuously falls into the feeder. The upper and lower loop units can be flexibly equipped according to user needs, and the number of units can also be selected as needed.
Equipment features
1. The drying effect can be achieved by adjusting the air volume, heating temperature, material residence time, and heating speed;
2. Flexible equipment configuration, continuous feeding and discharging, easy to use;
3. Multi layer setup, high utilization of hot air, energy saving;
4. The air inlet device ensures a more uniform distribution of hot air and guarantees consistency in product quality;
5. Due to the low temperature of the material, the equipment is not completely enclosed, leaving only the opening for the inlet and outlet, resulting in good moisture removal effect.
