SKLN Counterflow pellet cooler introduction:
SKLN Counterflow pellet cooler is mainly used for cooling high-temperature pellet feed after pelleting. It adopts the most advanced pellet feed cooling technology in the world and is one of the indispensable pieces of equipment for the feed mill production line.
SKLN Counterflow pellet cooler performance characteristics:
SKLN Counterflow pellet Cooler has a unique cooling mechanism. The cooling air moves in reverse with the high temperature and high humidity material, so that the material can be cooled gradually from top to bottom, avoiding the shortcomings of material surface cracking and the difficulty of moisture and heat dissipation in the center caused by sudden cooling of the general vertical cooler. which plays a good role in the production of high-quality granular feed, prolong the storage time of granular feed and improve the economic benefits.
The working principle of SKLN Counterflow pellet cooler:
1. The hot and wet pellets compressed by the pelletizer enter the inlet of the closed air feeder at the top of the SKLN Counterflow pellet cooler, and pass through the closed air feeder and the rhombohedral cone diffuser to make the pellets After the material is split, the granular material flows into the silo body from the front, back, left, right, and middle of the top part of the silo.
2. At the beginning, the granular material gradually accumulates. When the material is filled with the silo, when the material touches the upper-level device, the motor is turned on and starts to work. The motor drives the discharge frame to move back and forth left and right through the reducer and eccentric mechanism.
3. In the process of reciprocating discharge, when the relative position between the movable discharge frame and the fixed frame reaches a certain level, the material will fall from the silo body and pass through the gap between the movable discharge frame and the fixed frame. Discharge into the hopper. When the relative positions of the movable discharging frame and the fixed frame are staggered, the material is not discharged. The material is discharged out of the machine during this reciprocating motion. When the material level device is used, the motor stops rotating, and the discharging also stops correspondingly. When the material touches the upper material level device again, it starts to work.
4. During the entire working process of the cooler, the fan is always on, because the material flows from top to bottom, and the wind is opposite to the direction of flow of the material, flows from bottom to top, and the cold wind and The cold material is in contact, and the hot air is in contact with the hot material, so this type of cooler is called Counterflow pellet cooler. Due to the high temperature and water content of the particles in the silo, the material stays in the silo for a period of time. Through the suction of the fan, the natural air enters from the bottom, through the material layer of the silo body, for heat exchange. At the same time, the heat and moisture of the material are taken away by the fan, which can cool the material and reduce the moisture.
The scope of application of SKLN Counterflow pellet cooler:
SKLN Counterflow pellet cooler is mainly used for the cooling of pellet feed in the pelletizing section of large and medium feed mills so that pellet feed with a temperature as high as 80~90C and a moisture content of 17~18% from the pellet mill is cooled to a temperature slightly higher than room temperature. , The moisture is reduced to 12~13%, which is convenient for transportation, storage, and storage.
Advantages of SKLN Counterflow pellet cooler:
SKLN counterflow pellet cooler has a good cooling effect, high degree of automation, low noise, simple operation, and less maintenance. It is an advanced alternative cooling equipment widely used abroad.
