GINDERS, MIXERS, PELLET AND BRIQUETTE MILLS; DRIERS, STORAGE AND TRANSPORT OF FEED PELLETS -- RESEARCH NOTES 9/7/09
The equipment shown on this page represent investments of capital too large for a typical fish farm enterprise in Africa. The workable approach is for an area which has good, all weather roads and which has 100 or so fish farmers within a 20 mile radius, to support one milling operation. The farmers would bring the raw feedstock materials to a central site owned by the cooperative, and in return, would exchange for bagged feed for fish. The cost of processing and overhead would be recovered by the mill by returning to the farmer less that the material he brought would make into pellets. This surplus would be sold for cash to cooperative members or to the general market for fish food. Periodically, some of the net profits from selling the “surplus” would be returned in the form of patronage dividends to the members, divided based on the member's economic activity with the co-op.
This approach would allow fish farmers to contribute different feedstock amounts, not necessarily in exact proportion to make the fish feed pellets. The feedstock would include cracked corn and other grains which when steamed, would breakdown the starch which would serve as a binder and an acid buffer. The pellets would be of the sinking type so they could be added to underwater cribs for the fish to eat. When the fish eat the pellets, they break apart and produce “fines” which would normally sink to the bottom of the crib. Periodically, the fines could be removed and fed to shrimp and other filter feeders.
This approach would allow for year-around use of the mill plant which can adapt to different feedstocks which will change as the seasons change. Hosokawa is one of many suppliers of this type of equipment. The industry supports very large equipment. We need to look for small, less expensive equipment. The cooperative mill should be built inside 40 foot Intermodal cargo containers so that they can be moved if necessary. We would need a 6 x 6 semi with a front drive axle and two rear drive axles and a hook-lift flat bed. With different beds, the hook-lift is very versatile. A flat bed would haul equipment and machinery, tractors and pallets of materials, tanks and other large, bulky items. A tank bed would haul liquids. An open-top-box bed would haul chipped cellulose or cut greens and kitchen waste. An enclosed cargo bed would haul sacks of meal and other products in a safe, rat-proof, rain-proof enclosure.
Because of rodents, the storage of pellets could be in pallet sized, metal bins (one meter cube) with tight lids. The bin pallets would be secured to a flat bed and when bed were lifted to the ground, could be slid off onto the ground with a pulley system or a tractor. Each pallet would have a skid type or wheeled undercarriage. This transportation system would be in addition to the smaller ones used by the local fish farmers. This way the cooperative mill could serve members and markets much farther from the feed mill.
The metal bins would serve a second purpose. After pelletizing, the pellets need to dry to about 2 to 3% moisture content. The design would include the metal bins which have ports on the lower edge of one side, to which air ducts can be quickly attached and detached. When detached, a slide vent cap would be secured over the port opening. Vent pipe/ducts of galvanized sheet metal, about 20 feet long and painted black, would be attached to the ports. The ducts would be six inches in diameter, at the intake end of which would be a duct fan and a screen and filter to keep out bugs, pollen and spores. The Sun would heat the air in the tube, allowing the air to absorb more moisture than is in the ambient air. The ports on the lower edge of the bins will connect to internal array of two inch, perforated plastic pipe around which metal screen material is installed to prevent the pellets and fines from entering into the pipes. This array would by three by three (9 vertical pipes) or four by four (16 vertical pipes). The hot air will draw moisture from the pellets, go up the vertical columns and exit through ports in the lid to the bin. After drying, the lid and port covers would seal the pellets against drawing in moisture, pollen, dust and spores. The bins could also be made of heavy gauge, heat, UV, and rodent resistant plastic.
When the pellets are to be removed from the bin, the drying tube array is simply lifted out. The connection between the inside of the hot air output ports and the input side of the manifold for the array, need not be fixed, but simply lodged in a half-cup to hold the lower side of the inlet to the manifold even with the bottom of the vent port. The bins would be painted black.
Eight bins could be arranged on a concrete pad so that ducts extend in four directions. By putting wheels on the undercarriage, a bin could be move from the drying pad to a storage shed and from the storage shed next to the pond where the pellets are hand delivered to the underwater feeding cribs.
We could also co-locate a hatchery at the feed mill site so that the farmers could be widely dispersed, yet obtain consistent, high quality juvenile fish and/or shrimp, and the feed. Also, an aquatic meat processing plant could be co-located at the feed mill site so that it could process and ship fresh and frozen fish and/or shrimp to more distant markets. The trimmings would be boiled, settled and the fish oil skimmed and used as feedstock for transesterification into biodiesel and biolubricants, which plant would also be co-located at the same site. The nutrient-rich water from the settling tank would be used to infuse charcoal to make Agrichar or used as crop irrigation water. A Solar Furnace CHP system would provide the electricity, hot and cold water, steam, refrigeration, and heat for the energy needs of all of the plants. A WellSpringCatchment water conservation system installed on each fish farm, would assist in providing fresh, clean water for the fish ponds. As the water in the fish pond is changed, the waste water is nutrient rich and is a good source of irrigation water for most crops.

Pellet Die,Ring Die,Flat Die Pelleting Presses The process of pelleting consists of forcing a soft feed through holes in a metal die plate to form compacted pellets which are then cut to a pre-determined size. The machinery which has been developed for this purpose is now very diverse in design and there is much controversy between different equipment manufacturers as to which type is the most effective.

Feed Milling:

Pelleting is a key to the production of high quality nutrional feeds as they ensure that the feed formulation is in the correct quantities for all that eat them. Each bite of a pellet will have the same designed formulation ensuring all the stock are feed as intended.
Most pellet mills now have one or more conditioning units mounted above them where liquids such as water and molasses can be added to improve pelletability. Sometimes water added in the form of steam which softens the feed and partially gelatinises the starch content of the ingredients.

Pellet Press/Granulator/Pelletiser---Flat Die

AQUACULTURE FARMS - MUTUAL AID SOCIETY OF AMERICA, LLP The ZLSP series of Plane grinding granule feed machine can process the oil cake and other mixed waste material to granule at one time. And it is columned granule feed and have slippery firm. During the process of producing granule, the temperature can almost reach 70—80 centigrade. The ZLSP series flat die pelleting presses can make fecula into paste. The inner granule is cooked and fully penetrating, and is not easy to go moldy and degenerative. Then it can be stored for a long time and improve poultry dainty and assimilation function. It also can shorten the period of feeding, so this flat die pellet mill can efficiently guarantee many users’ productive cost.

------------------------------------------------------------]
Pellet Cooler for Aqua feed and Poultry Feed Mill Pellets from dry pelleters may exit at up to 88°C and 17-18% moisture. The temperature must be quickly reduced to ambient or less and the moisture level to 10-12% or less for proper storage and handling. Pellets must therefore be cooled and dried. Moist pellets, if they are going to be converted to dry pellets, also need drying although their temperature is not normally much elevated during manufacture.

Pellet Cooler:

Coolers/dryers are of two basic types, horizontal and vertical.
In the horizontal type of cooler/dryer (Figure 22) the pellets are conveyed on a perforated steel mesh or moving belt through which a cooling air stream is passed.
In the vertical type of dryer, pellets usually fall by gravity into a chamber through which air is sucked by a fan.

Feed Extruder,Feed Extruders for Aqua feed and Poultry The extrusion cooking process, because it causes a high level of gelatinisation of starches, results in feeds with good water stability. It can produce 'expanded' floating feeds as well as sinking pellets. The process also improves the digestibility of the product. However, extrusion cookers are usually very large and expensive to purchase and operate.

Pellet Extruder:

Feeds which have ingredients such as soybean meal and cereal grains can be made more digestable, and the nutrients are therefore more available. Floating feeds are made using extruders along with highly water-stable sinking feeds which can be made with extruders as well. In some cases, extruders are used just to prepare feed materials, such as dry extrusion of soybeans.
