Poultry Feed Pellet Making Machine

Cause of Poultry Feed Pellet Making Machine Blockage

In the process of compound feed production, the safe and normal production of the poultry feed pellet making machine is very important, because the poultry feed pelletizer completely completes the preparation of the poultry feed pellet making machine.

But in actual production, due to various reasons, it is easy to form a thick and hard material between the ring die and the pressing roller. The pressure roller cannot extrude the material from the die hole, so that the ring die of the poultry machine is stuck or slipped, causing the common blockage of the poultry pellet mill.

Through on-site analysis of multi-equipment and multi-material, the reasons for machine blockage are as follows:

1.The die roll gap is not suitable.

The gap between the die rolls is too large, resulting in an excessively thick material layer between the die rolls, uneven distribution, uneven pressure roll stress, and easy slippage. Once the extrusion force of the die roller on the material is less than the resistance of the inner wall of the die hole to the material, the material cannot be extruded, which will cause blockage.

In order to reduce clogging, attention should be paid to adjusting the gap between the die rolls during production.

When adjusting, it is best to form a state of closeness, rotation and non-rotation of the pressure roller and the ring die. According to observation, the gap is generally 3-5mm. In this process, the experience and adjustment feeling of the poultry feed pellet making machine are very important.

2.The effect of steam.

The most ideal production conditions in the production process of pellet feed are suitable raw material water, good steam quality and sufficient conditioning time. Proper use of dry saturated steam granules can effectively improve the output of the poultry feed pellet granulator and the quality of the granulated material.

In order to ensure good particle quality and high output, in addition to the normal operation of each transmission part of the poultry feed machine, the quality of dry saturated steam entering the conditioner of the poultry feed pellet making machine should also be guaranteed.

Suitable saturated steam has softening and lubricating effect in the granulation process, which can improve productivity, reduce frictional heat energy, and prolong the service life of ring die; it can reduce power consumption and promote starch gelation.

Fiber-to-fiber bonding; it can improve the particle forming rate, reduce powder, make the material appearance smooth and clean, and improve product competitiveness. (Related case: Feed Mill Plant In Uzbekistan)

The poor quality of the steam makes the moisture of the material too high when it leaves the conditioner, and when it enters the particle cavity, it is easy to cause blockage of the die hole, and the pressure roller slips, causing blockage.

Specifically:

①Insufficient steam pressure and high water content can easily cause the material to absorb too much water. At the same time, when the pressure is low, the temperature of the material is also low during conditioning, the starch cannot be gelatinized well, and the granulation effect is poor;

②The steam pressure is unstable, fluctuating high and low, and the material conditioning is unstable, resulting in large fluctuations in the current of the poultry feed making machine, uneven thirst of the material, and easy blockage in the normal production process.

The poultry feed pellet making machine should always pay attention to factors such as steam pressure, conditioner feed rate, etc., to avoid excessive moisture in material conditioning caused by steam pressure and water content. At the same time, in order to reduce the number of blockages caused by steam quality, the boiler room should provide high-quality, stable dry saturated steam.

In the production process, the poultry feed granulator should always pay attention to the moisture content of the quenched and tempered material, which can be judged by a simple method. The specific method is: grab the material of the conditioner, hold it by hand, and release it.

3.The influence of conditioning effect.

In order to make pellet feed meet the competitive demands of the market, its excellent quality must be guaranteed. The conditioning effect of the material before granulation is very important, because it directly affects the output and quality of the poultry feed pellet making machine, especially the water stability of special aquatic products is an important indicator.

If the material cannot be completely conditioned and matured before granulation, it is difficult to guarantee the water stability index. The so-called conditioning refers to the pretreatment of powder materials before granulation, which is the process of fully stirring and absorbing the powder to be granulated and an appropriate amount of steam in the conditioner.

Select the conditioning equipment that meets the technical requirements, so that the material can be fully stirred and mixed with steam in the conditioner to achieve the effect of softening the material and gelatinizing starch, which is conducive to the compression molding of powder and produces qualified products.

The poultry feed pellet making machine conditioner requires a long period of heat preservation, heating and humidification, and the number of layers can be installed in any combination as required to ensure that the material can fully meet the requirements of conditioning, improve the surface and internal quality of the granular material, and improve its water resistance in water. At present, the most ideal conditioning effect can be achieved by using the method of Modulator+Qualifier+Modulator.

Through on-site debugging, the number of blockages of the poultry feed pellet making machine can be reduced by adjusting the steam. As the boiler equipment has been formed, the steam provided has been determined.

Pay attention to the treatment method of water vapor in the steam pipeline, try to exclude the condensed water in the steam pipeline, and the steam pressure at the front end of the conditioner should be very stable.
