FeaturesSame world—Create different
Jiangsu Liangyou is a professional manufacturer of crab special aqua feed processing equipment and provides complete sets of turn-key projects. From the breeding point of view, compared with the traditional rearing methods, use of scientific and reasonable formula, combined with advanced processing technology and high-quality feed, high performance, low-pollution processing equipment, and ultimately produced crab special aqua feed can guarantee crab and other special aqua animals to be more healthy and efficient growth, leading to higher benefits to farmers.
The processing flow designed by FDSP professional team can greatly utilize the feed raw material, reduce waste, and feed is highly commercialized, regular specifications, guaranteed quality, which provide good breeding conditions for breeders and industrial farmers of special aqua feed such as crab and shrimp feed, social benefits are obvious.
1, crab special aqua feed production line - can be customized recommendations :( a production line: 1-4 tons / hour; multiple production lines: 3-20 tons / hour or more) detailed process flow scheme:
Raw material receiving and cleaning—first grinding—first batching and mixing—second grinding—second batching and mixing—pelleting/extruding —cooling/drying/spraying—packing.
(1) Raw material receiving and cleaning up: stored in silos or warehouses of raw materials, since the feed will produce a lot of dust, and the raw material will be mixed with some impurities, so the doghouse need a separate filter device and raw materials through early Cleaning and permanent magnet cartridge to remove impurities (including metallic impurities), the follow-up into the station;
(2) A crushing: raw material for particles of sorghum, wheat, etc., need to use the hammer mill which coarsely crushed;
(3) The primary ingredients mixed: After coarse particles were pulverized material, the powder feed meal and other raw materials have been delivered to the batching bin, then use batching scales ingredients, using a ribbon mixer, mix the ingredients;
(4) The secondary pulverization: Due to special aqua animal's digestive system is relatively special, so crushed to a very fine particle size of the feed, so after a crushing and primary raw ingredients mixed need to use micro hammer mill or vertical shaft Advanced Micro Devices mill for secondary grinding;
(5) Secondary mixing ingredients: raw materials in the secondary ingredient when mixed generally require the addition of various liquids (such as vegetable oils, animal oils, oil phospholipids) and manually add some premix;
(6) Pelleting / extrusion: raw materials through full and subtle ingredients after crushing, according to demand, through feeder, conditioner, pellet mill or extruder, can produce a finished particle;
(7) The cooling / drying / after spraying: from the pellet mill and extruder out of the finished higher temperature, but also the need for cooling (high moisture extruded material, it is necessary to dry, and because the extruded material advantage lies in its fat content higher, so it needs to be after spraying to enhance fat and fat content of the feed, thus improving feed FCR;
(8) Packing: Finished will be temporarily stored in a warehouse of finished, packaged and then weighed, weighing before packing, need to be screened to ensure that the finished product does not contain powder particles.
3, key equipment in crab special aqua feed production line:
Crab special aqua feed processing technology provided by the Jiangsu Liangyou, pellet mills, and extruder are critical components:
Special aqua dedicated pellet mill:
Pellet mill is mainly composed of feeding, conditioning, pressing, transmission and lubrication system components. Their work is to require moisture content of not more than 15% with the powder from the hopper into the feed auger, by adjusting the variable speed motor speed, to get the right material flow, and then enter a stirrer, a stirring rod and stirring steam mixed quenching and tempering, if you need to add oil or molasses, also tempered together with the steam from the mixing tube is added, the amount of oil added less than 3%, otherwise it is difficult molding powder after quenching with temperatures up to 90-110 ℃ humidity of 14 ~ l 7%. Then through alternative means for removing iron absorption by mixing the powder chute in iron impurities, and finally into the suppression chamber pelleting.
In special aqua feed production line, pellet mills generally used for the production of heavy material, such as shrimp and other materials. FDSP pellet mill production has the following characteristics:
(1) Simplified and feed circular feeding frequency feeding;
(2) Used quenched three jacketed conditioner or DDC, speed and adding steam system is installed in the form of specially designed blades, quenching the shaft to ensure that sufficient material can be quenched aging;
(3) the cutter mechanism fixed to the cabinet, open the door without leaving the knife blade against the surface of the ring mold, blade allows fast replacement (plug-in);
(4) Design of special shrimp feed roll and pressure roller surface in the form of improvements to the average area of each pressing blade using the original feed material, even material distribution.
The main technical and performance parameters:
Shrimp feed pellet mill
Note: The capacity of the pellet mill usually by formula, quenching effects, particle diameter, the compression ratio factors, ring mold quality, please contact one of our professionals, and tell us your specific needs, we will specifically for you customized to meet the needs of your production line.
Special aqua dedicated Extruder:
Extruder has a screw and a nut, with mixing and kneading functions. Extruded material into the cavity after the material between the screw nut squeezed, friction and shearing effect, the internal pressure rising, the largest of 4Mpa, the temperature rising up to 140 degrees Celsius. 3-7s sharp rise in the temperature and pressure of time, the organizational structure of the material changes, further gelatinized starch, protein denaturation, crude fiber damage, kills harmful bacteria Salmonella bacteria. High temperature and high pressure from the discharge of material out of the mouth allow the sudden release of pressure suddenly, the moisture partial flash. After cooling the material was porous structure, the material of the expanded form of pellets, flocculent or coarse crumbs form.
FDSP pellet mill production has the following characteristics:
(1) High capacity, good performance, low power consumption, low noise, beautiful appearance;
(2) operate, reliable, high degree of maturation of extruded material;
(3) DDC conditioning has good effect;
(4) Feeders variable frequency motor speed control, the speed can be adjusted freely;
(5) Mobile cutter holder, the cutter speed variable frequency motor control, can be cut into different lengths of the particles;
(6) Using a variety of extrusion die orifice shape to meet the production needs of different foods;
(7) Can a machine, both floating feed production, but also the production sinking feed, but also used in the pretreatment of feed ingredients;
(8) Density control system to facilitate the production of floating and sinking feed combination.
The main technical and performance parameters:
Wet single screw extruder
Wet twin-screw extruder
The advantages of crab special aqua feed production line (quality aftermarket installation)
Different product quality, process design provided by the supplier is not the same, poor quality equipment, it will affect their life, failure rate, affect the quality of the products produced, and if the design process is unreasonable, it will affect production, resulting in waste of resources and other adverse consequences.
Jiangsu Liangyou equipment provided, chooses the high quality raw materials and accessories, through sophisticated processing to ensure product quality and performance, experienced design staff, according to your request, provide you with the most reasonable process design. In addition, professional installation team and excellent after-sales service, make sure that you use and worry-free operation.
The following is a Division I customized a domestic feed production lines installed pictures, which included the production of 3 to 4 tons of shrimp feed production lines:
In addition, the FDSP can also customize your premixes, concentrates, livestock and poultry feed, ruminant feed, pet feed, aqua feed and other various other common feed production lines, welcome your advice.
