After introducing the wet extruder, let's talk about how to reduce the energy consumption of fish feed production. Since the production of fish feed cannot be completed by an extruder, we will use the fish feed production line as the basis to introduce how to reduce production energy consumption and how to reduce your fish feed production cost.
Extruded feed has broad application prospects and is more superior than other feeds. The most basic thing is to provide sterilized and matured feed for the animal body, thereby reducing the risk of disease of the animal body, and at the same time improving the production performance of the animal body. With the development of science and technology, high technology has been widely used in the feed industry, the popularity of extruded materials has become more and more widespread, and environmental protection issues have become more and more stringent. The production of coal is not allowed, and only biofuels can be used. The higher it is, it reaches about 250 yuan/ton, which has a greater impact on production costs. After understanding, the steam consumption of each feed factory to produce one ton of extruded feed is between 230 and 580 kg/ton. The difference is so large that it is very surprising. Therefore, it is necessary to discuss the energy consumption of extruded materials. Everyone knows that the energy consumption of the puffing host is about 8%, most of which is the energy consumption of the dryer, so the focus is on the analysis of the energy consumption of the fish feed dryer.
The energy consumption of the dryer: Mainly to dry the extruded feed, to dry about 24% of the moisture from the host to about 11% of the moisture; the energy consumption is normally about 15% (the latent heat of vaporization of water is 2260KJ/Kg , (24%-11%) x 2260 = 294). The steam pressure is 0.6MP, and the steam enthalpy value is 276KJ/Kg; the theoretical value requires about 11% of steam. So, how to control the amount of steam used by the dryer?
（1）Analysis from the above formula
①It is necessary to reduce the moisture of the host material as much as possible (less than 24%), but ensure the degree of puffing and appearance quality; the host material has less moisture, which can reduce steam consumption;
②The moisture content after drying should be controlled as much as possible (higher than 11%), but the moisture content of the finished product should not exceed 10.5%. The higher the moisture content after drying, the more the steam consumption will be saved;
a. Pay attention to the moisture difference of the material not to exceed 2% (the lower the better, the better to control the moisture after drying, which can save steam);
b. Pay attention to the thickness of the material layer (preferably not more than 30mm), it must not be higher than 80mm, the energy consumption will be greatly increased;
c. The distributor should distribute uniformly to ensure the uniformity of the material layer, so that it is easy to control the moisture after drying and save energy;
d. The air volume must be controlled reasonably and not too small. Too small, the hot air cannot penetrate the material, and the drying effect is not good; too large, may cause the material to accumulate in piles, causing uneven drying and increasing the difference in moisture; too small and large will waste heat and fail to save steam effect.
（2）From the process analysis
①The material entering the dryer enters as high temperature as possible, and the hot material is dried to avoid the material being dried after cooling down, which will cause waste. If the temperature of the material is low, the heat energy is also wasted to heat the steam, resulting in a waste of heat energy;
②Use low-temperature drying as much as possible in the drying process. Low-temperature drying not only saves steam, but also ensures product quality;
③Extend the drying time as much as possible, preferably more than 30 minutes, the longer the drying time, the more steam will be saved;
④The process arrangement cannot produce bottlenecks in other places, causing downtime for materials or packaging, resulting in increased steam consumption;
⑤The sieving effect should be good (at least 24 mesh screen, preferably 30 mesh screen), to avoid mold blockage or fiber hanging knives that cause downtime and increase steam consumption;
⑥The warehouse to be expanded must be stainless steel, otherwise rust will cause mold blockage, affect the continuity of production, and increase steam consumption.
（3）Analyze from operation
①Pay attention to the leakage of steam, especially the steam leakage of traps, to avoid wasting steam; many companies do not pay attention to this problem, and the proportion of waste is also large, please pay attention to it;
②Pay attention to controlling the air volume of the dehumidification fan (the hot air must penetrate the material, but not make the material fly) and the dehumidification temperature (control at about 65℃);
③Pay attention to the airtightness of the inner door of each drying area, and do not short-circuit the hot air in each work area (many companies do not pay attention to this), causing a waste of steam;
④Pay attention to the speed of the chain crawler to ensure that the drying time and the thickness of the material layer are reasonable; the hot air can penetrate the material layer and ensure a reasonable drying time to reduce the waste of heat;
⑤Do the airtight work of the dryer to reduce the waste of heat, thereby saving steam heat;
⑥The production plan is to mass produce as much as possible, reduce the time for product change, and reduce the loss of steam;
⑦Increase the one-time production rate, reduce the number of re-production, and reduce steam energy consumption;
⑧Full load production, improve production efficiency and reduce steam energy consumption;
⑨Accumulate production process parameters, different particle diameters, different production capacities, different expansion degrees, and different lengths, and the control drying temperature is different. The smaller the particle diameter, the lower the production capacity and the higher the expansion coefficient. The shorter the particle length, the lower the drying temperature needs to be. Try to control the moisture of the finished product at about 10% to avoid excessive drying, resulting in low yield and increased steam consumption; the higher the moisture of the finished product, the more steam energy consumption can be saved;
⑩Improve the skills of the operators, reduce the number of heads and tails, reduce the time for product change, reasonably control the mold moisture, reasonably control the mold temperature, reasonably control the expansion degree, improve production efficiency, and reduce steam energy consumption ;
⑪Clean the heat exchanger frequently to ensure normal heat exchange and avoid waste; generally clean at least once a week;
⑫Frequently clean up miscellaneous materials and powder in the dryer to reduce the absorption of heat energy by the miscellaneous materials and cause waste;
⑬When changing varieties, pay attention to controlling the opening and closing time of the dehumidifier fan to reduce the waste of heat;
⑭When changing varieties, pay attention to controlling the on and off time of the circulating fan to reduce the waste of heat;
⑮When changing varieties, close the steam valve in time, and advance the amount to reduce the waste of heat;
⑯Pay attention to steam pressure, we need high pressure, dry and stable, at least 6 pressures, the lower the steam pressure, the higher the energy consumption;
⑰Pay attention to cleaning the puffed conditioner once a week to remove some clumps and hard debris and fibers to avoid mold blockage and hanging knives, which will cause shutdown and cleaning and increase steam consumption;
⑱Pay attention to configure the corresponding mold and cutter head, quickly change the mold and clean up, improve efficiency and reduce energy consumption.
（4）From device analysis
①Try to choose a dryer with a drying time of more than 30 minutes; a dryer with a drying area of 30 square meters/ton, the larger the drying area, the better the drying effect, and the more steam will be saved;
②Try to choose a feed dryer with high humidity in the upper layer as much as possible; if the existing equipment is not like this, the hot air from the upper and lower layers is pumped, please modify the equipment as soon as possible to ensure that the steam energy consumption Saving;
③Try to choose a dryer that can recycle hot air with low humidity as much as possible, make full use of the hot air, and save steam; if the existing equipment is not like this, the upper and lower hot air is partially recycled, please Transform the equipment as soon as possible to ensure that the hot air with high humidity is pumped away, and the hot air with low humidity is retained for recycling, saving steam energy consumption;
④Try to choose dryers with independent drying layers for each chain and crawler layer as much as possible; avoid bad airtightness, causing hot air short circuit; waste steam; if the existing equipment is not separated, please modify it as soon as possible to avoid waste ;
⑤Try to choose dryers with the same air intake of each chain and crawler layer as much as possible; avoid bad sealing, causing hot air short circuit; waste steam; if the equipment air path is not like this, please adjust the air path to ensure that steam is saved ; It is necessary to choose multi-layer chain crawler drying equipment as much as possible, so that the material is turned many times to ensure the uniformity of the moisture of the material, and the moisture difference is small, and the moisture can be reasonably controlled to save steam.
If you can do the above work, I believe you can save heat to the utmost extent, and the steam energy consumption in the production of your extruded feed will achieve unexpected results. I believe that the energy consumption of the floating fish extruded feed you produce only needs about 230 kilograms of steam per ton, which greatly saves your production costs.
