After the palm fruit is harvested, it need to be sterilized wthin 48 hours. The purpose of sterilization is to destroy the enzymes in the fruit and avoid the increase of free fatty acid content in the oil. At the same time, the high temperature can soften the fruit, which is beneficial to the next threshing station.

Palm oil is generally processed by sterilization. The sterilization process serves the following processes. As a kind of improtant palm oil machine, palm oil sterilizer (sterilizing machinery) serves the following purposes.
Palm fruit sterilizer is the main equipment in palm oil mill. The type of sterilizer technology utilised in the palm oil mill greatly affects steam and power demand, and performance of the sterilization process. In general, palm fruit sterilizer can be diveided into three kinds: Horizontal sterilizer, Vertical sterilizer, Tilting sterilizer.
Horizontal sterilizer occupies large area and more steam consumption.
Vertical sterilizer is cost low steam consumption and save energy, also occupy less space.
Tilting sterilizer, is is more flexible, energy saving.
The horizontal sterilizer is the most commonly used sterilizer in palm oil mills. When disposed in a horizontal position, the cylindrical vessel sterilizer has fairly good disposition because the oil palm fresh fruit bunches placed in cages with a low stacking height are more uniformly spread out in this position across the length of the elongated vessel, as opposed to a vertical sterilizer. Thus, when pressurized steam is injected into the interior of the horizontally positioned cylindrical vessel, the steam can reach out to different directions and corners of the contents within the cages thereby helping treatment of the fruit bunches. Due to the low stacking height of the fruit bunches in the cages, condensate drains out freely from the fruit bunch stack facilitating heat penetration. The low stacking height also limits fruit bunch compression that facilitates low oil loss from the fruits during sterilisation.
Vertical sterilizers are available in several variations where fresh fruit bunches are placed directly into a tall vertical vessel without steel cages. The vertical sterilizer is considered for use in palm oil mills where space saving is important. Vertical sterilizers are much cleaner and easier to operate than conventional sterilizers.
Another type of sterilizer technology, the Tilting sterilizer eliminates much of the machinery associated with conventional sterilizers. The technology is the latest design that offers improved milling efficiency, and reduced labour and maintenance cost.

* The heat treatment helps destroy oil-splitting enzymes and seizes hydrolysis and autoxidation.
* In large scale palm oil mill plant, where the fresh fruit bunches (FFBs) need to be cooked whole, the steam weakens the stem of the fruit and reduces the effort required to get the fruit from the bunch with mere tumbling in the threshing machine or shaking.
* The heat is very important since it assists in solidifying proteins that contain the oil-bearing cells that are microscopically dispersed in it. This process of protein solidification/coagulation enables the oil bearing cells to collect together and flow with much ease when pressure is exerted.
* Further, the fruit is subjected to cooking to weaken the pulp structure, make it soft and easy to remove the fibrous material and its components during the process of digestion. High heat is recommended to partially disband the oil containing cells found in the mesocarp and further allows the oil to flow more readily. This stage of processing is very important.
* During sterilization, the moisture produced by the steam helps to chemically disintegrate the gums and resins. If this is not done, the resins and gum will cause foam during frying. Since part of the resins and gums are soluble in water, you can choose to apply wet steam to dissolve them in water such that they can be easily removed during clarification. Even the starch contained in the fruit can be hydrolyzed and removed in the same way.
* High-pressure steam is recommended for sterilization to cause the (warm air) moisture in the nuts to expand. Reducing the pressure causes contraction of the nuts and detachment of the kernels within their shells.
* After detaching the kernel from its shell wall, the nut cracking operation then begins. This clearly demonstrates that sterilization is therefore the most important process here. It is a pre-requisite for the success of all other palm oil processing processes.
* On high-pressure steam heating, the sterilization systems causes the bunches to loosen the fruits. This is critical because it helps the palm fruit bunches loose less water during the process.

The most standard modern palm oil mill production process for large-scale palm oil mill plant is sterilizer - thresher - digester - presser - filtration. The processing of raw materials generally follows the principle of sterilizing the palm fruit bunches first and then separating the palm fruit. The reasons why palm fruit needs to be sterilized first are as follows:
1. Increase the moisture of the fruit and offer convenience to separate the fruit from the fruit bunch;
2. Destroy the activity of lipid-decomposing enzymes, decompose tissues, and slow down the rancidity of fruits, so as to prevent the free fatty acid(FFA) content from increasing;
3. Make oil molecules condense on the surface, destroy the internal structure, and facilitate pressing.
In palm oil production process, we need to use many palm oil processing machine, palm fruit sterilizer is the first equipment to be used in the process of palm oil processing. It’s mainly used to is to boil the palm fruit bunch to facilitate the separation of palm fruit from bunch.
As we all know, mature palm fruit bunches collected from palm orchards cannot be directly processed as raw materials for palm oil processing. Otherwise, on the one hand, it may cause damage to the palm oil pressing machine and affect the processing progress; on the other hand, it may absorb palm oil and reduce the oil yield. Therefore, it is necessary to use palm fruit sterilizer to process palm fruit bunches to get the palm fruit.
The primary principle of the sterilization section is to use high-pressure steam to treat fresh palm fruit bunches. This heat treatment serves multiple purposes: it kills any microorganisms present, softens the palm fruit, and helps separate the palm fruit from its bunches, making it easier to process.
The basic principle of steam sterilization, as accomplished in an autoclave, is to expose each item to direct steam contact at the required temperature and pressure for the specified time. Thus, there are four parameters of steam sterilization: steam, pressure, temperature, and time.
In summary, the vacuum dryer in palm oil mills uses the principle of decompression to efficiently and gently remove moisture from palm oil, combined with precise control of temperature and other factors, to produce high-quality palm oil products while saving energy and maintaining nutritional value.
