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.
Various kinds of palm fruit sterilizer
After the palm fruit is harvested, it need to be sterilized wthin 48 hours, the purpose of palm fruit sterilization station is to prevent enzymes broken down, avoiding FFA content in oil further increase, at the same time, the temperature will make the fruits soften, palm fruit sterilization station makes it easy for threshing, pretreatment expelling, prepare for the following process, such as digesting & pressing, it can also reduce the damage of kernel.
The following discussion on the different types of sterilizer:
Horizontal Sterilizer
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.
Horizontal sterilizer
Vertical Sterilizer
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.
Vertical sterilizer
Big capacity vertical sterilizer
Tilting sterilizer
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.
