High-quality pet food should not only satisfy people's purchase needs in appearance, but also the nutritional needs of animals. Only advanced production technology and equipment configuration can meet high-quality pet food production standards. The appropriate production models are selected mainly according to the customer's formula requirements and investment capabilities. The domestic pet feed complete production line has developed rapidly in recent years. The Pet food production line ranges from small-scale to large-scale production line engineering installation, and there are many models to choose from. And the technology has greatly improved compared to before. A simple Pet food production line includes: crushing mixing puffing drying seasoning packing processes, 2-5 operators can complete the whole factory’s production requirements. A simple Pet food production line configuration can meet the production needs of less than 1t/h. Dry production and processing are used below 200kg/h, and wet production is recommended for more than 200kg/h. With the same production formula and extruder model, wet production is 1.5-2 times higher than dry production.
The automatic Pet food production line equipment process runs from feeding, cleaning, distribution of raw materials, storage, automatic weighing, crushing, mixing, puffing, drying, spraying, cooling, and packaging lines to meet the production requirements of 1t/h or more. Indispensable. (1. The labor intensity is not up to the standard. 2. Increasing the labor force will increase the later wages and increase the production cost.) 5-10 operators will complete the production demand. Large-scale production lines mostly adopt plant infrastructure construction based on equipment production requirements. One can reduce the use of land area, and the other is to save part of the transportation equipment investment. The current domestic extruder production process is divided into single-screw extruder and twin-screw extruder. Single-screw extruder has great advantages over twin-screw extruder in terms of investment, but single-screw extruder has a problem with the equipment model. There is no problem in the production of pet feed with low protein and fat content. When producing some products with higher fat and protein content, or when changing the product formula (usually defined as high-end pet food), there will be several comparisons with inferior single screws. Difficult problems (spraying, unstable discharge, bad shape), which refer to the defects of most domestic manufacturers' equipment under normal circumstances. There are a few well-known domestic companies in the regular large factories that do very well. Like Muyang extruder, Gemdale Sanfu extruder, how to select pet food processing equipment ，Jinan FLD Extrusion company mechanical extruder . Buhler extruder and wennger extruder abroad. All of them are professional manufacturers who have made outstanding contributions to high-volume extruders. Promoted the rapid development of domestic pet food machinery. Small-volume single-screw extruders cannot meet the needs of a wide range of users because of the large number of manufacturers, no core technology, cruel competition and cost issues, and they must be equipped with wet production to meet the production requirements of the final product. Small-volume single-screw workmanship It is also relatively rough, and the equipment is not of good grade in the workshop. Even if the product is well done, it is not decent enough when the customer inspects the production plant. Limiting product price advantages
Small-volume twin-screw extruders are mainly concentrated in Jinan, Shandong. These manufacturers were first manufacturers of puffed food production. The process of puffed food production is very similar to that of pet food production lines. Therefore, the equipment and workmanship are all processed according to food-grade production and the appearance and workmanship are very beautiful. After more than ten years of development, most manufacturers in Jinan can provide a complete set of pet food production line configuration and production requirements. In terms of equipment use, the technology is already relatively mature. As long as there are better masters in production, there is no problem with equipment operation.
During the operation of the twin-screw extruder, due to the twin-screw feeding, the feeding will be smoother and more stable, and no lumps will be formed at the feeding end, so the processed products will be very stable, precisely because of the characteristics of the equipment , It is the best choice when processing pet food with high oil and protein; and the twin-screw extruder is very convenient to clean the machine after it stops. The screw has a self-cleaning function, which greatly reduces the cleaning time and labor intensity compared with the single-screw cleaning. The screw does not need to be disassembled. In terms of the difference in the production of aquatic feed, in short, the twin screw has the following advantages compared with the single screw: the twin screw can produce high-energy formula with a fat content of 11~13% (foreign sources say up to 17%), while the single screw generally does not More than 6~8%.
The unique double screw conveying capacity of the twin screw, when producing particles with a diameter of 2mm and below, the twin screw machine can accurately control the production of floating materials, submerged materials and slow-sinking products. The drying process is also an important part of the production process. The level of energy consumption determines the cost of the product. The high-quality drying box has a very high heat utilization rate. The small-output models mostly use multi-layer belt-type electric heating drying boxes. Large-scale feed drying box energy consumption will be much higher, but the investment cost will be low, you get what you pay for. The high-quality drying box has low energy consumption, low loss, no dripping, low-cost drying box, thin insulation layer, inconsistent materials, affecting product quality, and cutting corners in some invisible places. When selecting the equipment, you must pay attention to the oven carefully. Small details can tell whether a manufacturer’s workmanship is fine or not, which will directly affect the use of the equipment during the production process. Spraying: the same as the same, as long as it meets the production process and mixing requirements. Choose by yourself.
