Concentrated feed production line-automatic batching premixing unit

Specializing in the production of feed machinery and complete sets of projects, it can provide customers with livestock feed (pigs, etc.), poultry feed (chicken, duck, geese, etc.), ruminant feed (cattle, sheep, etc.), ordinary aquatic feed (four major home fish, etc.), and special Complete set of aquatic feed (shrimp, crab, etc.), extruded aquatic feed (floating and sinking fish feed, shrimp, etc.), premix (including various additives, etc.), concentrated feed, pet food (cat food, dog food, etc.) Equipment solutions to meet the different needs of customers.

Definition of concentrated feed: Concentrated feed is a mixture of protein feed, additive premix, and mineral feed in a certain ratio. It is an intermediate product of complete feed, that is, semi-finished feed, which cannot be directly fed to animals.

Taking the 15T/hour concentrated feed production line project as a case, the following introduction and explanation are given based on the process flow and each section.

Raw materials: Common raw materials include soybean meal, bran, cotton meal, wheat flour, fish meal, various essential amino acids, vitamins, and inorganic salts.
Process introduction:

The processing characteristic of concentrated feed is that it does not contain granulating line, the batch is mixed to minimize the classification, and it is directly packaged. This concentrated material production line is designed with an hourly output of 15T/H. It adopts a crushing line, double-scale automatic batching, a mixing line, and a finished product packing line. The total power of the equipment is about 230KW; the construction area of the production area is about 10×11×24m (height); the whole line is compact in design, reasonable in structure, meets environmental protection requirements, and can be oriented design according to customer requirements.
Process characteristics and section introduction:

Raw material receiving and cleaning section: In this section, the pellet feeding cleaning and powder feeding cleaning are separated independently, and the dust is removed separately, and the dust removal effect is good.
Cleaning equipment: SCY80 granular material sieve, designed to produce 20-30T/H per hour; powder sieve SQLZ60×50×100, designed to produce 10-15T/H per hour.
Crushing section: This section adopts one crusher and two smashing bins, which can alternately replace crushed varieties. Before the raw materials enter the warehouse, impurities are removed by a magnetic separator to ensure the safe operation of the crusher.
Crushing equipment: crusher SFSP668×800, 110KW, designed to produce 10-15T/H per hour.
Batching mixing section: This section uses 16 batching bins, two batching scales are used for batching at the same time, controlled by the batching program independently developed by our company, to realize accurate fast and slow feeding, fast batching speed and high precision.
Weighing equipment: batching scale PCS10/PCS05, batching accuracy: dynamic ≤ 3‰, static ≤ 1‰. Mixing equipment: mixer SHSJ2, (18.5KW, 1000kg/batch), designed to produce 10-15T/H per hour. Mixing uniformity CV≤5%.
Packing section: There are 2 finished product warehouses in this section. The finished product warehouse is specially designed for storing powder materials. The unique anti-grading device is designed in the warehouse to effectively prevent material grading and arching. Finally, the packing scale will automatically weigh and pack.
Packing equipment: auger scale (special packing scale for powder materials), packing range is 20-50kg/bag, 4-6 bags/min.
Auxiliary section: Dust removal system to improve the working environment of workers; grease addition system, which is added at common mixers, to improve the palatability of feed.

According to the needs of different customers, the solution can be optimized for configuration:

1. This scheme uses a single-point dust removal mode, that is, each rotary distributor (powder) and granular material cleaning screen is equipped with a pulse dust collector, which has a good dust removal effect. Single-point dust removal is a humanized design for our company, providing a better working environment, but the cost increases, and customers can consider whether to adopt this configuration according to actual needs;

2. The number of silos can also be adjusted according to the customer's formula, the characteristics of the raw materials and other factors to achieve the highest utilization rate and effectively control the production cost;

3. The installation form of the silo can also be fabricated or welded. The cost of fabricated silo is higher, the installation on site is quick and convenient, the cost of welding silo is lower, the workers are welded on site, the labor intensity is large, and the time is long. Users can choose reasonably according to their needs.


Automatic batching premixing unit
Definition of premix: Premix is the abbreviation of additive premix feed, which is to dilute one or more trace components (including various trace mineral elements, various vitamins, synthetic amino acids, certain drugs and other additives) The intermediate compound feed product is made by mixing the agent or carrier according to the required ratio and uniformly mixing. Premix is an important component of complete compound feed.
Process characteristics and section introduction:

Combining the characteristics of easy cross-contamination and classification of the premix, this design adopts the carrier upgrade, from the silo to the packaging all the way to the bottom, the material is completely flowed down by the process, which can effectively prevent the cross-contamination and cross-contamination caused by re-lifting and conveying. Graded risk.

Raw material receiving and cleaning section: cleaning up impurities in raw materials to ensure the quality of products and the safety of subsequent processing equipment.

Cleaning equipment: powder sieve SQLZ60×50×100, 5.5KW, designed to produce 10-15T/H per hour.

Batching mixing section: This section adopts two batching scales, 4 carrier bins are weighed separately, and 8 small bins are weighed separately. The trace elements are added manually and equipped with inspection scales. After the material ingredients are completed, they enter the mixer for mixing, and finally fall directly into the finished product warehouse.
Weighing equipment: batching scale PCS-05/PCS-02, batching accuracy: dynamic ≤ 3‰, static ≤ 1‰. Mixing equipment: mixer SDHJ.2, 18.5KW, 1000kg/P, designed to produce 6 tons per hour (premix). Mixing uniformity CV≤5%.
Packing section: The finished product premix after mixing is directly dropped into the finished product warehouse, and then enters the buffer hopper of the packaging scale through the closed air feeder, and finally weighed by the automatic packaging scale, and inserted into the label by the special packaging. And carry out the seam.
Packing equipment: premix special packing scale, packing range 20-50kg/bag, 3-5 bags/min.
Auxiliary section: Dust removal system, dust removal at the feeding port and packing port to improve the working environment of workers.

According to the needs of different customers, the solution can be optimized for configuration:

1. In this solution, the trace elements are added manually, and customers can choose an automatic feeding element addition system according to their needs;

2. The number of carrier silos and small silos can also be adjusted according to the customer's formula, the characteristics of the raw materials and other factors to achieve the highest utilization rate and effectively control the production cost;

3. Dust removal system is configured at the packing area to improve the working environment of workers. Customers can choose whether to configure it according to their needs.
