Castor Oil Cake Product Overview
Castor Oil Cake is a natural by-product obtained after mechanical extraction of castor oil from castor seeds, containing residual oil and organic nutrients. It is widely used as an organic soil conditioner and nutrient source, valued for its slow nutrient release and soil health benefits.
This product is primarily intended for agricultural and non-food applications, where organic matter and plant-based nutrients are required.
Manufacturing / Processing (High-Level)
Castor Oil Cake is produced through:
- Mechanical pressing of castor seeds for oil extraction
- Partial oil removal, leaving controlled residual oil content
- Drying, crushing, and sizing based on end-use requirements
Processing is designed to maintain nutrient integrity and stable physical form suitable for handling and field application.
Raw Material Origin
The product is derived from Indian castor seeds, sourced from established castor-growing regions. Seed quality directly influences nutrient composition, oil residue, and cake consistency.
In-House Quality Control & Consistency
Quality control focuses on:
- Residual oil content
- Moisture level for storage stability
- Uniform particle or cake size
Batch-wise checks ensure consistent nutrient availability and handling behavior.
