To make cottonseed oil, usually need cottonseed oil press machine, cottonseed oil extraction machine and cottonseed oil refining machine. Here is the flow of cottonseed oil pretreatment and press process:
Cottonseed oil extraction process:
1, the extracting device adopts stainless steel fixed grid board, frequency conversion speed regulation, extracting machine storage tank self- automatic control, high extracting efficiency, low energy consumption, extracting condenser, steam degassing condenser, stripping condenser, evaporative condenser, the final condenser are aluminum alloy tube-type condenser, the condensation effect is fast.
2, wet meal dissolution using DTC evapo-separated machine, dissolution, drying in one machine. The production of finished meal powder is fine, good color, evapo-separated machine material levels are self-control.
3, the use of film evaporation process, evaporation temperature is low, crude oil quality is good, energy saving, evapo-separated machine second times steam waste heat utilize as the first evaporator heat source.
4, Steam-lift oil and steam-oil heat exchange, save energy.
5, the tail gas recovery uses the water bath type tail gas recovery device, the tail gas recovery two times utilization, reduces the solvent consumption.
Cottonseed oil refining machines:
1. Decoloring tank: bleach pigments from oil.
2. Deodorizing tank: remove the un-favored smell from decolorized oil.
3. Oil furnace: provide enough heat for the refining sections which need high temperature of 280°C.
4. Vacuum pump: provide high pressure for bleaching, deodorization which can reach 755mmHg or more.
5. Air compressor: dry the bleached clay after bleaching.
6. Filter press: filter the clay into the bleached oil.
7. Steam generator: generate steam distillation.
