PLG-2200/8 type disc dryer
First, the process conditions
1. Material: Amino acid solid particles
2. Initial moisture content: 10%
3. The final moisture content: 0.2%
4. Wet product yield: 500Kg / h
5. Dry product size: 20-40 mesh
6. Dried product accumulation weight: 1.2 g / cm3
7. Drying temperature: 140 ℃
8. Heating method: steam (0.5MPa)
9. Equipment Material: All 304 stainless steel
10. Installation: indoor
11. Power: 380V 50HZ
12. Environment: 20 ℃ 760mmHg φ = 80%
Process calculation:
1, dry product yield at 0.2% per hour: G dry = 451 kg / h
2, moisture evaporation per hour: W = 500 × (10-0.2) ÷ (100-0.2) = 49kg / h
3, 10% of wet product output per hour: G wet = 500 kg / h
Wet material into the dryer before the temperature is 20 ℃; when the drying temperature is ~ 80 ℃;
4, the heat must be evaporated water, water vaporization heat to take 595 kcal / kg:
Q1 = 49 × 595 = 29155 kcal / h
5, heat the material must be heat, the specific heat of the material to take 0.4 kcal / kg • ℃
Q2 = 451 × 0.4 × (80-20) = 10824 kcal / h
6, wet materials in the water necessary for heating the heat, water specific heat to take 1.0 kcal / kg • ℃
Q3 = 500 × 0.1 × 1 × (80-20) = 3000 kcal / h
7, dryer area:
Q total = 42979kcal / h
Heat conduction drying heat transfer formula: Q = KA △ T
Which K generally take 30
△ T == 87 ℃ then A = 16.5 square,
Considering the lower final moisture content of the material, and the lower the moisture the slower the drying rate, according to experience,
It is proposed to use PLG2200--8 type disc continuous dryer 1 to meet the requirements
Second, equipment selection and main technical parameters
According to the requirements of the proposed use of PLG2200-8 type disc dryer 1 Taiwan

The main working principle:
 Amino Acid Dish Dryer Wet material is continuously fed from the feeder to the first layer pan of the dryer. The rake arms with the rake leaves make a rotary motion, causing the rake leaves to continuously invert the material and the material flows along the exponential helix Dried disk surface, the material on the small dry disk moved to the outer edge, and in the outer edge of the outer edge of the big dry disk below, the material on the large drying plate to move inside and fall into the next layer of small Drying plate, the size of the drying plate alternately arranged up and down, the material can be continuously flowing through the entire dryer, the hollow drying plate into the heating medium, heating medium from one end into the other end of the export, the dried material from the last layer of drying tray To the bottom of the shell, and finally rake leaves move to the expected discharge. Evaporation of water vapor from the set at the top of the wet exhaust port exhaust filtered by a pulse dust collector and discharged outside. The bottom of the dry material discharged directly packaged.
