Innovative solution:

Our company's independently developed internal heating fluidized bed nitrogen closed-loop drying process has the advantages of safety and reliability for the special properties of materials, and is widely used in biochemical and organic material drying systems.

Innovative technology:

Wet materials enter the internal heating fluidized bed through the feeding device, and nitrogen gas enters the fluidized bed as a fluidization medium. Under the action of hot nitrogen gas, fluidization is formed in the built-in heat exchanger area. Steam is passed through the heat exchanger in the drying section, and most of the heat required for material dehydration is provided by the heat exchanger; The dried material enters the fluidized bed cooling section for cooling, and the cooling capacity of the cooling section is provided by the cooling water in the heat exchanger. The qualified products that have been dried and cooled are discharged into the internal heating fluidized bed. Nitrogen carries away water vapor and trace dust from the internal heating fluidized bed, and after being subjected to cyclone dust removal and high-efficiency washing tower dust removal and cooling, they are recycled.

Program features:

Nitrogen closed-loop circulation ensures system safety and stability;

The fluidized bed adopts a special design to effectively avoid material adhesion, and a three-layer leak proof material air distribution plate is specially designed;

The fluidization speed is low, and the bed design adopts an enlarged structure to reduce the concentration of tail gas entrainment;

The special fabric structure at the inlet ensures even dispersion of wet materials entering the fluidized bed;

High heat utilization rate, the main heat required for drying is provided by the built-in heat exchanger, and the thermal efficiency can reach 90%,;

Single machine processing capacity is large, the system occupies a small area, and saves investment.

Solution implementation:

As a leader in the domestic organic chemical drying industry, the Organic Chemical Division of Shandong Tianli Drying Co., Ltd. has strong design and processing capabilities, rich on-site experience, and a comprehensive after-sales quality assurance system. At the initial stage of design, based on the material parameters and system requirements provided by the user, accurate equipment models, equipment layout drawings, equipment foundation drawings, and other design materials will be provided to the customer.
