The advantages of using pelleted feed are:
- The heat generated in conditioning and pelleting make the feedstuffs more digestible by breaking down the starches.
- The palatability of the feed is increased.
- The segregation of ingredients in a mixing, handling or feeding process is prevented. By feeding a pelleted feed, the animal is more apt to receive a totally mixed ration than one that has separated through these processes.
- Waste is minimized during the eating process. When pelleted feed is fed, each animal receives a well-balanced diet by preventing the animal from picking and choosing between ingredients.
- Bulk density is increased, which enhances storage capabilities of most bulk facilities. Shipping facilities are also increased, thereby reducing transportation costs.
- Feed in pellets forms reduces natural losses because it reduces the formation of dust.
- The time and energy consumption for the prehension of the food is decreased.
By combining moisture, heat and pressure on feed ingredients, a degree of gelatinization is produced which allows animals and poultry to better utilize the nutrients in these ingredients. Consequently feed conversion will be improved.
There are many types of pellet mills that can be generally grouped into large-scale and small-scale types:
- Large scale pellet mills are usually used to produce animal feed pellets, wood pellets, and fuel pellets for use in a pellet stove. It is mainly used in large scale commercial production with the features of long working life, high output and low consumption.
- Small-scale mills are usually applied for home use with the advantages of low cost and easily move. By working principle, it can be divided into screw presses and hydraulic presses. The same basic process is used for both types. A die, also known as a mold, holds the uncompressed powder in a shaped pocket. The pocket shape defined the final pellet shape. A platen is attached to the end of the screw (in a screw press) or the ram (in a hydraulic press) which compresses the powder.
Pellet mill capacity is one of the most discussed topics at compound feed production.
Provided that conditioning with saturated steam is optimized, the following points are decisive for the press capacity (throughput):
active die surface (open area)
installed power drive
requested pellet quality: for example, a pellet mill running at 30 t/h with broiler feed in the US or South America produces 15-20% fines, but in Western Europe only 3% fines (PDI 97%) are accepted, resulting in a throughput of only 25 t/h
Press capacity depends substantially on pellet quality (stability according to the PDI, Pellet Durability Index). Durability of pellets shall be determined by tumbling the test sample for 10 seconds at 500 rpm, in a dust-tight enclosure. PDI is a number that describes the percentage of remaining pellets that are not reduced to fines after being agitated under controlled time and conditions by various mechanical means.
Feed distribution is the most overlooked factor in a pellet mill operation.
The distribution must be uniform on the working track of the die. Otherwise, the rolls work badly and, in addition to the loss of productivity, there is the risk of clogging the die with the consequent lockup of the machine. The rotary feed cone and the correct positioning of the deflectors are fundamental for the correct distribution of the product.
When feed distribution is controlled properly, spreading material across the entire working track, the production capacity of the pellet mill is increased. An uneven distribution causes irregular wear of the die and consequently a productivity lower than expected and a premature wear.
