The Corn cob is the cob of the corn ear which is removed from the grain, accounting for 20%-30% of the weight of the corn cob. The structure is divided into three parts. The corncob powder manufacturer will tell you about the processing of corn cob:
First, the rough part of the corncob surface, that is, the drumstick layer.
Second, the middle part of the corn cob, hard and elastic, called the corncob wood layer, accounting for 60% of the total mass of the corn cob.
Third, the corn kernel is the innermost, soft part, soft and white, called corncob sponge floc. The sputum and cavernous parts account for about 40% of the total corn cob.
Processing of corn cob
Roughing of stored corn cobs, the optimum moisture for roughing is 12% to 18%. After the impact and grinding of the machine, the corn cob is processed into particles having a particle size of 5 to 10 mm. The roughed material mainly includes corncob granules and coarse mash, which is called a mixture. Among them, 40% of the particles and 40% of the coarse.
Separation of material separation Material separation is carried out simultaneously with roughing. The reason for this is that material separation is a critical step in corncob processing. This process separates the corncob mixture by wind selection, and the size of the wind is determined by the ratio of the material to the value of the product. The particles selected by the wind are called semi-finished products, and the drumsticks are rough corn cobs.
Before processing, the irregular semi-finished product must be extruded into a sheet having a thickness of 2 to 2.5 mm, which can speed up the crushing, increase the yield and the weight of the finished product. The compressed semi-finished product is then broken using mechanical impact, shear and friction. The material at this time is a smaller particle and a number of particles.
