Palm Kennel Oil Production
Palm kernel oil is a type of edible vegetable oil extracted from the seeds, or kernels, of the oil palm fruit (Elaeis guineensis). It is distinct from palm oil, which is obtained from the fleshy mesocarp of the fruit. Palm kernel oil has a high content of saturated fats, particularly lauric acid, which gives it a semi-solid consistency at room temperature and a high melting point. It is widely used in the food industry as well as in non-food products.
Proper kernel pre-treatment is necessary to efficiently extract the oil from the kernels. The feed kernels must first be cleaned of foreign materials that may cause damage to the screw-presses, increasing maintenance costs and down time, and contamination of products. Magnetic separators commonly are installed to remove metal debris, while vibrating screens are used to sieve sand, stones or other undesirable materials.
Step one: Crushing palm kernel
The first step is to crush the clean palm kernel into small pieces by using the crusher, which aims to increase the palm kernel oil yield and reduce the pressure of the palm kernel oil pressing equipment. The crusher can be used as a single-machine equipment and also suitable for home use with small processing capacity.
Step two: Cooking palm kernel
The second step is the cook the palm kernel by using the cooker, which aims to bring the temperature and humidity of the palm kernel to the optimum before pressing to increase the palm oil yield. It is a very important step before the pressing. For small capacity, we can use drum cookers, we have 3 types of wood-burning, electric and gas, and for larger capacity, we can use vertical steam cookers. Our steam cookers has the advantage of sufficient heating power, reliable operation, wide fuel applicability and better safety performance.
Step three: Pressing palm kernel
The third step is pressing through palm kernel pressing equipment. Palm kernels are very hard, and our screw palm kernel oil pressing equipment are squeezed using the short two-pole pressing process, which is more suitable for hard oil seeds. Also too long pressing time will lead to paste, so we specially designed to ensure high palm kernel oil yield, but also to avoid pasting. Our squeeze screw is forged with No. 45 steel, forged and dipped in fire, with high hardness. This palm kernel oil equipment has been well received by many clients.
Step four: Filtering palm kernel oil
After we get the palm kernel oil, we can use the filter to remove the impurities in the palm kernel oil, the most commonly used is the plate filter. It takes away the impurities in the gross oil by the action of squeezing, followed by filtering out part of the water. The plate filter produced is widely used and with good performance. At this point we have the clean palm kernel oil.
