Harmless equipment processing process: material by pre broken by material pump delivered to cans; high temperature and high pressure steam sterilization, discharge pressure and exhaust screening, dust and exhaust gas processing, storage material weighing, packing, storage, drying, degreasing, cooling treatment.
A: incoming link
This link is considered under high temperature and high pressure treatment charging equipment problems, and taking into account the harmless treatment must be raw, cooked separately the relevant provisions of, workshop design two layer (a layer of processing equipment, second layer of raw materials), both to reduce workers into the labor intensity of the material and avoid the material everywhere to sprinkle, random drift caused by with the refined multiphase defects (such as poultry feathers, etc).
B: hydrolysis pressure relief and waste gas treatment
Through the high temperature and high pressure treatment, the material enters the hydrolysis tank, and enters the process of pressure relief and exhaust. Exhaust gas first enters the dust buffer tank, through the exhaust gas after the dust enters the condenser processing, to the small amount of gas condensate after waste purification tower spray treatment, tail gas at the end of the through biological adsorption adsorption tank. So the entire pressure relief exhaust gas is completely processed and decomposed to achieve emission standards.
C: drying process
After pressure relief is completed, enter the material drying stage. Drying process design is a batch production process. The material is fed into the dryer through the spiral conveyor, which mainly considers the water vapor of the material.
D: oil, material separation
After drying, the material directly into the rake storage silo storage; in accordance with the processing capacity of the screw press, sequential entry oil pressing part, material separation. The output of the cake into the cooling process, the output of the oil into the heating oil tank, after the deposition of the oil tank storage.
E: cooling, dust and related waste gas treatment process
The separated material is fed into the cooler by a sealed screw conveyor. Including during the drier, cooler, conveyor exhaust all through the spiral down dust is closed, lower dust processing by induced draft fan aspiration condenser processing.
F: screening and crushing, storage and packaging process
After cooling the material, by the screw conveyor into screening crushing machine, grinding materials and then, through the wind machine is composed of a spiral dust mouth into storage silo connection on the packaging bag storage.
The process has the following characteristics:
1, high temperature and high pressure, sterilization, steam is not directly contact with the material.
2, fully automatic process, closed production, no waste gas, waste water, waste residue discharge.
3, the processing cost is low, no need to add any auxiliary products.
4, resources can be recycled, the by-product of high value-added.
