Energy-Saving And High-Performance Fixed Convection Dryer For Grain

Fixed Convection Dryer

   Summary

     1, Working principle
A fixed convection dryer is a type of fixed bed dryer in which materials are laid flat on a drying bed, and hot air passes through the material layer to dry wet materials. The machine uses ventilation directional valves on both sides to change the air direction, forming a convection staggered drying mode, which can make the hot air flow from top to bottom or from bottom to top, so that the material is heated evenly on both sides, drying more thoroughly, improving the drying efficiency, and the quality of the dried material is better.
     2, Performance characteristics
(1) Energy saving and efficient
Fixed convection dryers can use heat pump technology, which has significant energy-saving effects. Each kilogram of water consumes about 0.3-0.4kWh of electricity, saving over 40% energy. If the valley off peak electricity consumption mode is adopted, the energy-saving effect can reach over 60%.
In terms of grain drying, it can fully utilize heat energy, reduce heat waste, and improve energy utilization efficiency.
(2) Good drying effect
Can adapt to various food crops, such as corn, wheat, sorghum, rice, etc., adjust drying parameters according to the characteristics and initial moisture content of different crops, ensure that the grain reaches the appropriate moisture content, and guarantee the storage and processing quality of the grain.
(3) High reliability
Low product failure rate, safe system operation, and long product lifespan. The annual maintenance cost is only 1-2% of the cost, with low operating expenses and reduced worries during use.
(4) Operational flexibility
The speed of the mesh belt conveyor is controlled by frequency conversion, which can meet the requirements of various types of processes. In grain drying, parameters such as drying time, temperature, and air volume can be flexibly adjusted based on the type of grain, initial moisture content, and target moisture content after drying.
Can adapt to different heat sources, such as Heat pump, coal, biomass, desiel, gas, etc., and choose the appropriate heat source based on the user's actual situation and cost considerations.

      3, Structural composition
Conveyor chain system: responsible for stably conveying materials to the drying area, ensuring the continuity of materials during the drying process.
Drying unit system: It is the core part of the entire dryer, generating hot air and exchanging heat with materials to achieve the drying function.
Automatic circulating air system: allowing hot air to circulate within the drying equipment, improving energy efficiency and reducing energy consumption.
Automatic feeding system: realizing automatic feeding of materials into the drying equipment, improving work efficiency and reducing manual operation.
Automatic discharge system: After drying is completed, the material is automatically sent out from the drying equipment for easy collection and processing in the future.
