What machines are common feed processing machinery

Below, commonly used feed processing machinery is introduced according to the process of feed processing.

① Feed crusher

The feed crusher is mainly used to shatter various feeds and various coarse feeds. The purpose of crushing the feed is to increase the area of the feed surface and adjust the particle size, increase the surface area and increase the palatability, and the contact with the digestive fluid in the digestive edge is conducive to improving the digestive rate , Better absorb feed nutritional ingredients. On the one hand, the adjustment of the granularity reduces the energy of chewing for livestock and poultry, and on the other hand, it is more convenient for transportation, storage, mixing and granules, and better efficiency and quality. The feed crusher uses the force of impact, shear, rubbing, etc. to crush the feed into a small particle processing machinery. Commonly used are three types: hammer, claws and hammer type.

② Feed piercing machine

Poly feed to suppress the feed processing machinery of particle feed. The raw materials for suppression include dried grass powder, powder coordination or mixed feed, straw or dried grass, etc. The granular feed is heavier, and it is not easy to absorb moisture, which is convenient for transportation, storage and mechanized feeding. It contains uniform ingredients, which can prevent livestock and poultry picky eaters, increase feed remuneration, and reduce waste.

Commonly used feed pressure particles include two types: ring mode and peace mode, which is the most widely used in the ring mode. 1) Circle modulus particles are composed of feeding buckets, spiral feeders, mixers, ring pressure molds, pressure rollers and fixed cutting knives. The raw material is sent from the feed bucket to the mixer through the spiral conveyor. The steam sprayed by the nozzle is mixed with the ring mold. The vertical -configured ring mold is rotated in a clockwise direction to drive the cut roller that is cut with it. The feed is strongly squeezed in the wedge -shaped area between the ring mold and the pressure roller, pressed out of the mold hole, and was cut into cylindrical shape by a fixed cut knife. The quality of the particles suppressed by the granular machine is better, but the machine structure is more complicated. 2) The pressure of the flat mold pressure particle is disclosed and placed horizontally. The pressure roller is rotated with the pressure mold on the pressure mold, and the feed mold hole is formed and pressed out. Simple structure, convenient manufacturing, but low productivity.

③ Feed mixed machine

Realize feed processing machinery with a uniform distribution of various feed components in the process of feed production. Also known as feed mixer. There are two types of feed mixed machines: intermittent and continuous according to their operating methods; there are two types of stand -up and horizontal type according to the configuration of the main axis; Essence The first three types of working parts are used to mix dry powder and humid materials, and paddle -leaf type is used for mixed rare feed.

④ Feed puffer

After the feed raw material is lonely, the fragrance increases and the palatability is increased, which can stimulate the appetite of animals. At the same time, the extent of the long -chain structure of organic matter such as protein and fat increases the degree of the short -chain structure, so it becomes easier to digest.

The puffer is a key equipment for feed puff production. At present, the most widely used feed industry is single screw extrusion puffer. Single screw squeezers are divided into two types: wet type and dry type. The dry -type puff is only the dry steam heating pre -quality before the raw material enters the puff. The pressure and temperature in the cavity should not be too high, and it is mostly used for the puffed of feed raw materials, such as the puff of all -fat soybeans.

The difference between the wet -type puff and the dry -type puff is that it can both add the steam to the steam of the feed in the pipe and the steam, add water to the steam, add water, and add the steam. There is also a water -adding device at the mouth of the material, which can be added according to the condition of different puffed materials. At the same time, to control the temperature of each section of the puffed cavity. High, you need to dry first and then cool. The wet -type puff can also be used as a dry puffer, but the spiral head needs to be replaced. Wet -type puffers are mostly used to produce full -price feed products, such as suckling pigs, fish and shrimp and other aquatic feeds.

⑤ dryer

The commonly used dryer -type dryers, plow -knife -type dryers, fluidized bed dryers, and drum -type dryers commonly used in feed factories. This article only describes the horizontal dryer and plow knife -type drying cooler.

The horizontal dryer uses the steam disk to force the power, thermal air, and the hot air is introduced into the drying box by the fan. The drying box is set in the drying box to set up a single layer or double -layer crawler bed. After the machine, the thickness of the material layer is adjusted and the material is evenly distributed to the entire width of the material bed. The hot air passes through the bed with a hole with a hole, and the material running on the bed will be dried and dehydrated, and the hot and humid air will be discharged from outside the fans. The operating speed of the ingredients is adjusted by a stepless speed regulating motor. The material water is high, and the operating speed is slowed, and it is faster. This dryer is more suitable for production of puffed particles.

The plow knife -type drying cooler is a device that integrates material drying -cooling. The machine consists of two parts: drying section and cooling section. The material first enters the drying section. After the hot air import, the material was heated and dried by the hot air during the stirring of the plow knife, and gradually sent to the cooling section. The cooling section from the air inlet from the exit end is inlet, and the air outlet setting in the middle of the device can cool through the air -to -air switch to cool the heat of the material and cold air. This device is more suitable for drying and cooling after the feed raw material is swollen, such as drying and cooling after the whole fat soybean powder is swollen.

⑥ cooler

The more commonly used cooler in the feed factory has a horizontal cooler. The roller cooler, the countercurrent string cooler, the vertical cooler, etc. This article briefly describes the horizontal cooler.

The horizontal cooler has two types: single -layer and double -layer. Its basic structure is a feed adjustment mechanism, a parallel movement bed, a box that brings into the air outlet and the air -absorbing mouth, and the speed regulating mechanism. The cooling material is evenly distributed on the feed bed under the adjustment of the feed adjustment mechanism, and the material bed slowly moves to the other end under the chain. Under the action of the fans, the cold air enters the material layer of the air inlet and passes through the bed vertically, and absorbs the heat and water of the material to achieve the cooling and drying of the material. The operating speed of the ingredients is adjusted according to the temperature and moisture of the material. The material temperature is high and the water is high. Otherwise, it can be appropriately adjusted. The operating speed of the general material bed is between 0.15-1.5m/min.
