Description
Key words: fermented soybean meal dryer, soybean meal dryer, boiling dryer, low temperature boiling dryer, soybean meal dryer
Classification: Food Engineering Industry
Case overview: according to customer requirements, Haomai drying recommends the use of a special low-temperature boiling dryer for fermented soybean meal, model xf-16. The clean hot air is distributed into the bed through the air regulating valve plate, and the wet material entering from the feeder is boiling by hot air. Due to the wide contact between hot air and material, the heat and mass transfer process is enhanced, so it can be dried in a short time, Enter from one end of the bed, after boiling dry
Design technical conditions:
1. Material name: fermented soybean meal with bacteria
2. Initial moisture content: 37%
3. Final moisture content: 10-12%
4. Material specific gravity: 0.7
5. Feeding amount: 2000kg / batch
6. Inlet air temperature: 80 ℃
7. Heat source: indirect combustion coal-fired hot blast stove
8. Equipment material: material contact Q235
9. Drying time: 2h / batch
10. Air temperature: normal temperature, inlet air temperature: T1 = 80 ℃, exhaust temperature: T2 = 40-60 ℃, air moisture content: d0 = 0.01 kgwater / kg dry air
According to the drying temperature of materials and the bacteria carrying soybean meal made by our company, it is appropriate to select the intermittent boiling dryer. According to the calculation, the actual drying area required for drying is 6m2. The width of drying bed is 1m and the length of drying section is 6m. One set can meet the production requirements. Model of fluidized bed dryer: xf-1x6, drying section area: 6m2; selection of built-in cloth bags in the bed: the specification of bag selected in the bed is Φ 120 × 1600, the filtering area of each bag is 0.6m2, and the air volume entering the bag filter is V3 = 25000m3 / h, then the number of bags is n = 250
Working principle of special boiling dryer for soybean meal with bacteria:
The clean hot air is distributed into the bed through the air regulating valve plate, and the wet material entering from the feeder is boiling by the hot air. Because the hot air contacts with the material extensively, the heat and mass transfer process is enhanced, so it can be dried in a short time. It enters from one end of the bed body, after boiling drying, it automatically or indirectly flows out from the other end of the bed to complete the drying process. The soybean meal dryer can automatically feed in and out by adjusting the air volume of the fan's separator, and realize semi continuous production.
Characteristics of boiling dryer
1. The equipment is equipped with multiple quick opening doors to facilitate the cleaning of the main body, especially for the dead corners, the quick opening and back washing method can be used to clean the equipment.
2. Low temperature interval drying is used to control the quality of materials.
3. The built-in bag dust collector is adopted, and the compressed air is used for continuous dust cleaning, which can ensure the continuous and normal operation of the equipment. Large area dust removal bag area is adopted to reduce the filtering wind speed and ensure the service life of the bag.
4. The heating mode is steam heat exchanger heating and hot blast stove heating. The uniform hot air heat source with a certain temperature is used, and the automatic bypass valve is used to adjust the inlet air temperature.

Our company is responsible for guiding the installation free of charge to ensure the normal operation. We sincerely cooperate with all units with mature technology, high-quality product quality and after-sales tracking service!
