Description

Material feeding unit is used in feed processing

Technical Field

Background

The piglet diet should maintain a high energy concentration and low crude fiber, typically no more than 4% per kilogram of crude fiber with a digestibility of 14.7 to 15.5 megajoules, and to achieve such high energy low crude fiber levels, vegetable oils must be added to the piglet feed or higher proportions of whole expanded soybeans must be used in the formulation. The piglets within 7 days of age can better utilize glucose and lactose as energy sources, and the piglets within 7 to 10 days of age can utilize fructose and sucrose, and the piglets within 2 to 3 weeks of age cannot utilize starch in a large amount as energy sources due to insufficient pancreatic amylase and intestinal disaccharide enzymes in the digestive tract. However, the weaned pigs can be appropriately added with lactose and other components based on plant feed. The lipase activity of early weaned pigs is reduced, the utilization capacity of grease is limited, and researches have now shown that the shorter the fatty chain is, the higher the absorption and utilization rate is, the highest utilization rate of fat by the pigs is coconut oil, and the worst is corn oil and soybean oil, and lard and beef tallow. The addition of a certain amount of grease is convenient for granulating the feed in the processing process, and the addition of 5 to 6 percent of fat can play a role in lubrication during granulating. The use of the feeding emulsifier in recent years greatly improves the utilization rate of grease.

The main material in the feed accounts for 87 to 93 percent (weight ratio), the secondary powder in the feed accounts for 10 to 15 percent (weight ratio), the grease accounts for 5 to 6 percent (weight ratio), but the additive accounts for 0.8 to 1.2 percent (weight ratio). In the prior art, a large amount of time is required for stirring to meet the dispersibility of the stirred feed semi-finished product, and excessive increase of stirring time can cause layering of various materials with different granularity so as to reduce the uniformity of the materials, so that the conventional feed is mixed by a main mixer which is simply conveyed to the feed, and the uniformity of the dispersion of various materials is disadvantageous.

The application method of the product is as follows: as shown in fig. 1 to 3, before the main mixer 1 works formally, the secondary mixer 2 of the product needs to be used for fully mixing secondary powder and additives in advance, and the specific flow is as follows: the secondary powder stored in the second main material storage tank 8 is weighed by the first weighing tank 14 on the second main material conveying pipe 10 and then is conveyed into the secondary mixer 2 at a constant speed after being driven by the third blanking device 16 on the second main material conveying pipe 10; meanwhile, the trace element additive stored in the additive storage tank 9 is weighed by the first weighing tank 14 on the additive conveying pipe 11, is conveyed into the auxiliary mixer 2 at a constant speed after being driven by the third discharging device 16 on the additive conveying pipe 11, is mixed with the secondary powder entering the auxiliary mixer 2 under the stirring of the auxiliary mixer 2, and the conveying power of the third discharging device 16 on the second main material conveying pipe 10 and the conveying power of the third discharging device 16 on the additive conveying pipe 11 are controlled during the process, when the secondary powder and the trace element additive are completely conveyed into the auxiliary mixer 2, the auxiliary mixer 2 stirs the secondary powder and the trace element additive for a time to form a premixing intermediate material, and the premixing intermediate material is a powdery mixture of uniformly distributed trace element additive in the secondary powder.

When the premixing step is completed, the main mixer 1 can be used for producing a completely mixed feed semi-finished product, and the specific steps are as follows: different particle main materials corresponding to the first main material storage tank 6 are sequentially conveyed into the main mixer 1 through the first main material conveying pipes 7 corresponding to the first main material storage tank 6 according to the formula requirement, and are weighed according to the formula during the process through the first weighing tanks 14 on the corresponding first main material conveying pipes 7 and then are driven at a constant speed through the corresponding third discharging devices 16; at the same time, the premixed intermediate materials which are already mixed in the auxiliary mixer 2 are conveyed into the main mixer 1 through the premix conveying pipe 3, and are driven at a constant speed through the first blanking device 5 on the premix conveying pipe 3. When a plurality of granular main materials and the premixed intermediate materials enter the main mixer 1, the main mixer 1 is started to continuously stir the materials entering the main mixer 1, a first regulating valve 23 is opened, at the moment, the temporarily stored grease in a grease storage tank 19 enters a second weighing tank 22 through an oil transportation main pipe 18 for weighing, after the weighing is finished, the materials are pressurized by a first booster pump 21 and atomized by an atomizing nozzle 17 and then sprayed into the materials being stirred by the main mixer 1; finally, when the first booster pump 21 is operated for a preset time, the first booster pump 21 is closed, the compressed air delivery pipe 27 is opened, external air is filtered by the air filter 31, is pressurized by the air compressor 30 and then delivered into the oil delivery main pipe 18 between the first check valve 20 and the atomizing nozzle 17 after pressure feedback by the pressure sensor 28, and the grease temporarily stored in the oil delivery main pipe 18 between the first check valve 20 and the atomizing nozzle 17 is driven to be sprayed into the material being stirred by the main mixer 1 after being atomized by the atomizing nozzle 17, and then stirring is stopped after the main mixer 1 is operated for the preset time.
