Extruded feed floats in water and has a long stabilization time in water. It does not blister like other granular feeds. It can greatly reduce feed water pollution, reduce the incidence of fish, and is easy to feed. After the general pellet feed is fed, it sinks to the bottom of the water. It does not know how much the fish has eaten, nor does it know whether the feed is even. Therefore, the pellet feed must be put in once at a certain interval, and the amount of labor is large. The puffed feed is not the same, it can float on the water, how much the fish eat, how long to vote once, are clear, and save a lot of energy. Therefore, the use of extruded feed can not only reduce water pollution, reduce the occurrence of diseases, but also save the time and amount of feed, so it has been favored by farmers. In order to further reduce the cost of farming, some farmers have purchased feed extruders for their own use. For a time, feed extruders, especially small ones suitable for use on farms, have become popular commodities. The feed extruder is divided into single screw and twin screw, and the farmers can choose the model according to their needs. However, the expanded feed produced by the twin screw machine is superior to the single screw machine, and the quality is even better. Twin screw machine There are five major advantages: First, the conditioner is a dual-axis, dual-displacement regulator that extends the time of the material in the conditioner. The common single-axis conditioner has a tempering time of only 60 seconds. Now after two-axis insertion and output conditioner, it can reach the maximum time of 180 seconds. Second, the twin screws engage and rub each other, making the energy consumption lower than that of the single screw. This can make the material blending and curing more fully, its overall degree of aging can reach more than 95%, the other is the stability of the water can be maintained at more than 24 hours, while the particle surface finish and particle uniformity have reached the level of foreign countries. After the extruded feed is fully cooked, the fish will not only taste good, but also be easily absorbed. Therefore, when purchasing a feed extruder, it must be considered whether the degree of maturation of the material can reach 90%. Third, there is no restriction on the type of raw materials. Because the twin-screws are used to knead and squeeze each other, in the case of high-oil raw materials, they will not stick together and affect the operation of the machine. Therefore, the feed formulation can contain more than 12% of oil, which not only improves the quality of the formula, but also It slows down the wear and resistance of parts and reduces production costs. The single-screw feed expander can't do this. Once the feed has a high fat content, it will cause the feed to stick and the machine won't work. Fourth, there are many types of processed feed. It is mainly used in aquafeeds, such as fish and shrimp feeds, as well as river rafts and high-grade ornamental fish feeds. In addition, it can also be used in the food industry and pet feed processing, and the production cost per ton of feed is around 200 yuan. Fifth, it has a self-cleaning function. After the feed is produced, the machine will automatically extrude the internal surplus materials out of the machine, eliminating the need for farmers to remove them one by one to save time. In addition, the twin-screw extruder is also very productive. The extruder with a screw diameter of 80mm can produce 150-200kg per hour; the extruder with a screw diameter of 90mm can produce 500-1000kg per hour; the extruder with a screw diameter of 1lOmm has a higher production capacity. Each hour can reach 1500-2000kg, farmers can choose their own models according to their needs.
