De-oiled cake drying finishes the solvent-extracted residue from rice bran, mustard, groundnut and other oilseeds in Indian and Asian solvent plants. DOC is traded in large volumes for cattle feed and organic fertilizer, and its moisture strongly affects its price and storage. Plants dry it to reach buyer limits and to avoid lumps and mould in stock.
To dry de-oiled cake, GEM recommends the Paddle Dryer and Rotary Tube Bundle Dryer. Typical moisture is 15–22% in the feed and 9–11% after drying. Industrial Cooler is used when the feed or site calls for it. Every project starts with a pilot trial on your own sample.
A sealed paddle dryer heats DOC through jacketed walls and hollow paddles, keeping any solvent traces enclosed and breaking lumps as it dries. Steam-tube dryers suit larger plants with steam surplus, and a cooler conditions cake before bagging.
| Typical feed moisture | 15–22% |
| Typical target moisture | 9–11% |
| Recommended dryer | Paddle Dryer, Rotary Tube Bundle Dryer |
| Alternatives | Industrial Cooler |
| Application area | Pomace, Pulp & By-products |
| Industries | Animal Feed, Breweries & Distilleries, Agriculture & Grain Processing |
Meeting moisture specifications avoids price deductions and rejected loads. Dry DOC stores in bulk without caking and can be pelleted for easier export and lower freight.
Plants searching for a de-oiled cake dryer or comparing a DOC drying machine usually need three answers: which dryer fits, what it costs to run, and how fast it pays back. For De-oiled Cake, we start from your throughput, current moisture (typically 15–22%) and the target (9–11%), trial a sample on the Paddle Dryer, and return a sized recommendation with a budget quotation for your animal feed and agriculture operation.
