[0016] A method for using a jet granulation circulation system for fermented materials according to the present invention includes the following steps: SS01 The fermented materials are concentrated by a concentration device and then input into a liquid loop pipe. They are ejected downward in a state of tiny diffused materials through evenly distributed mixing nozzles in the area of the jet atomization section. SS02 The hot exhaust gas generated in the granulation tower is discharged into the preheating heat exchanger through an exhaust pipe and then discharged to the induced draft system through the cold exhaust gas outlet. At the same time, normal temperature air is input into the preheating heat exchanger for heat exchange and then transported to the bottom end of the conical cylinder part. SS03 The hot air is transported from bottom to top and continues to blow upward after passing through the holes on the particle support plate. SS04 The small particles of the diffused materials are blown upward by the hot air and are in a suspended state. The subsequent ejected diffused materials continuously adhere to the surface of the suspended small particle materials. The particles grow continuously and are continuously dried. When the particles reach a certain size, their weight exceeds the buoyancy force generated by the hot air and they fall on the particle support plate. SS05 When it indicates the material discharging time after working for a certain period, stop the material or gas transportation at the liquid loop pipe, the gas loop pipe, and the bottom end of the conical cylinder part. Drive the lifting cylinder and the gate cylinder to rise through the cylinder, and the finished particles on the particle support plate can be purged into the particle cavity through the purging pipe from the blanking interval. SS06 After purging for a certain period of time, control the cylinder to reset and stop supplying gas to the purging pipe, and continue the granulation process of SS01 - SS04. During the granulation process, discharge the materials in the particle cavity through the discharge port and bag them. SS07 Granulate and discharge materials in a cycle according to the above method.

[0017] The present invention has the following beneficial effects: 1. The present invention designs a novel granulation tower. By using tiny particles as the base material for granulation initiation, and through the buoyancy of hot air blowing, the particles adsorb and dry while in a suspended state, increasing in size. This significantly improves the granulation speed and uniformity. Through the design of a liftable gate sleeve and a purge pipe, intermittent discharging can be achieved, enabling continuous granulation in the granulation tower, improving work efficiency, and ensuring the drying effect and granulation quality.

[0018] 2. Through the design of a preheating heat exchanger, the present invention can exchange heat between the hot waste gas generated in the granulation tower and air, forming a hot void that is blown in from the bottom of the granulation tower, making use of the waste heat of the waste gas and playing a role in energy conservation and consumption reduction.

[0019] 3. Through the design of a double-sided conical filter rack, the present invention can avoid the problem of particles being discharged with the gas, playing a role in gas-solid separation. At the same time, the double-sided conical filter rack has the ability to vibrate, which can shake off the adsorbed particles, and also has the ability to flip, improving the service life and effect of the filter rack.

[0020] 4. Through the design of a conical cylinder part and an eccentric cylinder, the present invention can form a structure with inner layer ventilation and outer layer for collecting finished products, playing a role in saving space. At the same time, in cooperation with a liftable gate cylinder, an opening and closing structure of a finished product cavity can be formed in a small space, suitable for the conversion between granulation and discharging.

[0021] 5. Through the design of a purge pipe, the present invention can actively apply force to blow the products on the particle tray into the eccentric cylinder for collection in a pneumatic manner, improving the discharging and feeding efficiency.

[0022] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
