Jilin City produces more than 5 million tons of crop stalks every year. In addition to burning wood and fodder, more than 3 million tons are left. Nowadays, these straws, which can only be thrown away in the past, have new uses.
In many towns and villages in Longtan District, 8 straw wood pellet plants have been built to use straw to produce molding fuels. The price of straw fuel is 10% lower than that of coal with the same calorific value. During the combustion process, the calorific value can reach 3,800 to 4,200 kcal, and during the combustion process, there is no emission of sulfur dioxide and some waste. After burning, its waste is very good potash fertilizer. The rice straw and rice husk are crushed and processed into carbon rods and carbon blocks to replace coal. So far, Jilin City has 10 straw briquettes processing enterprises, 45 production lines, and an annual processing capacity of 300,000 tons. Relevant departments of Jilin City stated that during the “Twelfth Five-Year Plan” period, they will also invest 870 million yuan to focus on the construction of 17 key projects including biomass briquette, straw biomass central heating transformation, and biomass power generation, and strive to complete the project. Later, it replaces 410,000 tons of standard coal every year.

According to the motion state of the executive parts, flat die animal feed making machine has three kinds of moving roller type, moving mode and die roller double moving type. The last two kinds are commonly used in small chicken feed making machine, while larger models generally use moving roller type. According to the shape of the grinding roller, it can be divided into two kinds: cone roller and straight roller. The working principle of straight-roll moving-roll poultry feed production machine is shown in Figure 1: the motor drives the spindle through the reducer, which drives the grinding roller, and the grinding roller revolves around the spindle and rotates around the grinding roller shaft. Biomass, when the particles are processed raw material is fed into flat die machine feeding chamber, under the common role of distributor and scraper evenly on the flat die, driven spindle roller continuous rolled material layer, squeezing material into the die, material in the die hole forming type, such as process, after a certain time in cylindrical form being squeezed out, rotating knife cutting the material, the formation of particles, The granules are sent out by the sweep plate.
Biomass raw materials mainly contain cellulose, hemicellulose, lignin and other substances, and the forming mechanism between the die rollers of the poultry feed making machine is as follows (see Figure 2) :Feeding zone of the material under the action of gravity is clingy on flat die, when the roller rolling forward, deformation of material into the compression zone, then by extrusion, raw materials entering the particles, the gap between the air gap is expelled, each other between the particle position constantly updated, all gradually larger gap between particles was dominated by particles that can get into. With roller continue rolling, by compaction of raw materials into the extrusion area, part of the wedge area, die cone hole part and the first half belong to extrusion area, within the area, the pressure continues to increase, the particle itself deformation and plastic flow occurs, the perpendicular to the direction of maximum principal stress is extended, and continue to pack around the smaller gap, Due to the friction between the roller and the material effect intensifies and produce a lot of calories, which can soften, raw materials containing lignin adhesive force increases, the softening of the joint action of cellulose in the lignin and biomass, biomass forming gradually, then part of the residual stress in storage within the forming block and combined with solid particles but not very stable. The forming block enters the mold retaining section of the die hole under the action of extrusion, in which the residual stress which is not conducive to shape keeping is eliminated and the particles are shaped.
