1. Raw material cleaning
Receipt of raw corn and soybean meal in bulk; the clean-up process
is all operation units that pass the corn and soybean meal that has
passed the inspection of the raw material inspector into the silo.
In this process, the impurities in the raw materials are first
removed by the impurity removal equipment, and then transported to
the silo as planned by the receiving equipment and the
demagnetization equipment. The production line equipment includes
receiving devices (such as unloading pits, platforms, etc.),
conveying equipment, primary cleaning screens, and magnetic
separation devices (such as permanent magnet drums, permanent
magnet drums, etc.). For the receipt of bagged raw materials, it
means that the loading and unloading personnel unload the raw
materials that have passed the inspection of the raw material
inspectors and store them neatly in the warehouse. Four points
should be done in the process of receiving goods: 1. Accurately
count the quantity; 2. There is no quality problem in the raw
materials; 3. The receiving path is correct; 4. The receiving
environment is clean.
2. Ingredient process
The batching process is to weigh the raw materials in the batching
bin from the feeder under each batching bin to the batching
according to the formula requirements. After each raw material is
weighed by the batching scale, the raw material is transported to
the powder storage silo. The ingredients are weighed from the silo,
these weighed raw materials enter the powder silo, a small amount
of material and premix are added directly and manually weighed and
then put into the silo for mixing. The quality of the batching
process directly affects the accuracy of product batching.
3. Crushing process
The pulverization process means that the raw materials to be
pulverized in the silo are sent to the crusher to be pulverized
into powder, and then sent to the silo to be mixed by the conveyor
before use. The purpose of this process is to control the particle
size of the material. The design efficiency of the crusher in this
process determines the production capacity of the process
equipment, and it is also the process with the largest energy
consumption in the production of powdery materials. Monitor and
confirm hammers, screens, currents, noise and crushing paths at all
times.
4. Mixing process
During the mixing process, the crushed raw materials are discharged
from the mixing bin into the mixer, and oil is added to the feed in
the mixer through the liquid addition system as needed, so that the
components are mixed evenly and the desired mixing effect is
achieved. uniformity. The material discharged from the mixer is the
finished product, which is directly sent to the packaging process
of the finished product for packaging and leaving the factory. When
producing pellet feed, the mixed powder is sent to the silo for
granulation. In order to ensure the efficiency of the mixer,
maintenance personnel must regularly check and repair the
equipment, and regularly test the efficiency of the mixer.
5. Granulation process
The mixed material is quenched and tempered by magnetic separation
from the granulation bin, and then sent to the compression chamber
of the granulator, compressed into pellet feed, cooled by a cooling
tower, and sieved by a screening equipment to obtain standard
granules. Magnetic separation equipment must be cleaned regularly
to prevent iron impurities from causing damage to the granulator.
When quenching and tempering, the amount of steam should be
adjusted according to the requirements of the particle variety, and
the ring die (aperture, compression ratio, material, etc.) should
be selected according to the requirements of the particle process
quality. Particle temperature and humidity. According to the
variety, indoor temperature and humidity, season and other factors,
adjust the cooling tower to achieve qualified particle temperature
and humidity.
6. Finished product packaging process
The feed is weighed from the finished product warehouse by a
packaging scale, packed into packaging bags, and then labelled and
sealed by a packer, and then transported to the warehouse by a
transport vehicle for stacking.
