Floating fish feed machine start up process
DATE：2016/06/24
After all the preparatory work to be completed, the food extruder can be produced. Power at the beginning of the initial volume of feed production and feed generally choose the normal amount of 2/3 of the material to be added after the bypass flow from the first steam and steam condensate estimated emptying and then add water, so water can be prevented caused by excessive clumping material. When processing floating aquatic feed, water quenched after the material is about 26 to 28 percent (sink material in about 30 to 33%), the temperature after quenching material in between 90 ~ 95 ℃ (sink material in the 80 to 90 %between). Materials to be tempered to achieve the desired requirements and start the host and cutting motor, cutter initial number of revolutions of about 1200rpm steady.
After completion of the main motor starts, the feed material from the bypass into the cavity extrusion puffing, appropriate to add a little water inside when the host, and added steam is added about 1 to 3% of the expanded cavity, it is a good Processing appearance of floating particles (sink material do not need to add steam, but need to keep adding water, the addition of about 3% in favor of sink).
After the food extruder discharge adjust the number of revolutions according to the length of the cutter material. The main process parameters observed after a certain time interval material can be shaped and puffing machines.
