The current competition of feed companies is increasingly fierce, and the feed production has entered a low profit period, and its production cost has become one of the important factors affecting the benefits of feed enterprises. Production energy consumption, material loss, production efficiency, mechanical wear and other factors directly affect production costs, and feed companies must minimize production costs at competition. In addition to management factors in feed production and mechanical equipment factors, feed moisture is the most important factor affecting production cost. Scientifically use moisture to reduce production energy consumption, mechanical wear and process loss without reducing feed quality. Improve production efficiency, reduce production costs, while maintaining normal moisture of feed, and improve feed-outability, improve animal production performance.

1. Impact of feed water water on animal production performance MQF China feed industry information network – based on feed, service animal husbandry
Liu Chunxue, etc. (2004) studied in a mixer powder 0%, 0.5%, 1.5%, 2.5% of moisture on pig growth performance. The results showed that 0.5%, 1.5% moisture was added in powder, and the daily gain of pigs increased by 2% and 9% respectively, and the feed conversion efficiency was also improved. The reason is that after the addition of moisture, the gelation of starch and the durability of the particles during granulation process. Adding 2.5% water does not improve the growth performance of pigs because it is due to excessive moisture to reduce the ability of the material to absorb steam, thereby reducing the temperature of the temperature, which is not conducive to starch.

By smashing different apertures When the mesh, the water content before and after pulverization was compared. After the detection analysis, the moisture loss was significantly increased as the material was reduced. Similarly, the material of different gradient moisture content was compared before and after pulverization, the detection and analysis found that as the material water content increased, the moisture loss of the powder after pulverization increased, and the maximum loss of moisture was close to 1%. As the water content increases, the pulverization efficiency is also significantly reduced, and the energy consumption is significantly increased. A pulverizer equipped with a negative pressure suction and a damper adjustment device, with the increase of the air volume, the water loss still has increased trends. After corn crushing, the moisture loss was 0.22%, with a gas transport loss of 0.95%.

When the moisture content of the powder is less than 12.5%, it can be considered when the material is mixed, and the atomized water can be considered. However, there are many problems in this regard to note that the spray cannot exceed the 2% of the material during mixing, otherwise the moisture uniformity in the material is not good, and the feed is prone to mildew. Furthermore, spray the atomized water directly into the material, poor water in water, and add 2% water only 40% -50% water. Spray atomized water during mixing, 1 should consider the consistency of mixing time and moisture adding time; 2 To ensure uniform spray, adjust the position of the nozzle and the sprinkler size; 3 to pay attention to clear the inner wall of the mixer in time The residue of materials; 4 needs to add anti-mold.

2.3.4 Choosing the Material Ring Model of Suitable Specifications
MQF China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
The aperture and thickness of the material ring mold is not only the main factor affecting the production capacity of granulator, but also affects the moisture of the particulate feed product. Small aperture, due to its small diameter of its particles, the cooling air volume of the cooler is easily penetrating feed particles, so that the moisture taken away when cooling, and the moisture of the feed product will be low. Conversely, the well-diameter of the well is large, the particles are large, and the cold wind is not easily penetrating the particles, and the moisture taken away when cooling is less, and the moisture of the feed product will rise. For ring molds having a large thickness, during granulation, the friction resistance is large, and the material is not easily passed through the aperture, the extrusion granules, the friction temperature is high, and the water dispersed is lost, and the water particles are reduced, and therefore recommended When the method is ring mold, the aperture of the stamper is suitable.

Mildew has three essential conditions: moisture (water activity AW), temperature and oxygen. The effect of microbial on the mold is not accurately evaluated with feed moisture, and current water activity has become an important indicator for evaluating feed mold and mold toxin. Feed water activity is not only related to the water content of the feed, and the temperature and humidity are also related to the environment.

The water in the feed is free water and combined with water, and the water content in the feed is from steam pressure above the product. Size is determined. If the feed is placed in a sealed place, the moisture in the feed will be equalized because the evaporation of free water will reach the equalization state. Therefore, the vapor pressure (P) measured in a balanced state can determine how much is of the excess of the water. The steam pressure of the pure water measured in the same place is called PO. The water activity refers to the relative humidity of balance, and the AW value is used, the AW value is equal to P / PO. Femaic spores and other microorganisms have a chance to grow, which is determined by the AW value, rather than being determined by water content. Mildew and other microorganisms can utilize free water from materials. Most ways to increase moisture to feed in summer is to spray the water before the injection, but these moistures are easily utilized by microbes, so that the feed is moldy. Under different water activity conditions, the easily grown microorganism is different. When the AW value is from 0.91-0.95, the bacteria is most easily grown; when the AW value is 0.88, the yeast is most easily grown; when the AW value is 0.80, mold is most easily grown.

Bear Yiqiang (2008) indicates that the basic model of feed moisture control is to pay attention to the initial moisture of the mixer powder and determine the target temperature after steam treatment, and control the water moisture. When the initial moisture of the powder is less than 13%, some moisture can be added. Finished waterDon’t exceed 13%, otherwise there will be moldy dangers. Liu Chunxue et al. (2004) studied the impact of 0%, 0.5%, 1.5%, 2.5%, 2.5% of the moisture on the quality of the particles in the mixer powder. The results show that the water of the finished product is 11.02%, 11.33%, 12.01%, respectively. 12.32%, add 0.5%, 1.5% water in the finished product 65% water-keeping rate, and add 2.5% water only 50% water saver.

The main manifestation of feed mold is to pack mold in the package, and the surface of the feed particles is moldy. Its root cause is a temperature difference change, and the gathering occurs, resulting in the surface of the particles, and the water content of the packaging sealing site increases, causing moldy. In order to control the water activity of the feed, a surfactant and aqueous binding agent can be added to the water of the sprayed addition. Water binding agents and surfactants typically contain propionic acid, propionate, formic acid, sorbic acid, lactic acid, citric acid, and the like a plurality of organic acids. Organic acid molecules such as formic acid, propionic acid, sorbic acid have a strong induced effect on mold or the like; the powerful cushioning system formed by ammonium propionic acid and ammonium propionate can reduce corrosion resistance to the equipment. Therefore, the presence of a water bonding agent and surfactant avoids the surface of moisture to feed particles, combined with free water, thereby reducing the loss of moisture, ensuring that moisture in the feed particles, and plays water supply for feed effect.
