Livestock and poultry feed (ruminant feed) production line, extruded aquatic feed production line, shrimp and crab feed production line

Specializing in the production of feed machinery and engineering, 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 aquatic products Complete equipment solutions for feed (shrimp, crab, etc.), extruded aquatic feed (floating and sinking fish feed, shrimp, etc.), premix (including various additives, etc.), pet food (cat food, dog food, etc.), Meet the different needs of customers.

Now take 2×SZLH420 livestock and poultry feed (ruminant feed)+SPHS130×2 extruded feed+SZLH420X shrimp and crab feed production line project as an example, and make the following introduction and explanation based on the process flow and each work section.
The project mainly produces livestock and poultry feed, ruminant feed, extruded aquatic feed and shrimp and crab feed. It is a comprehensive feed production line. It produces 20 tons of livestock and poultry feed or ruminant per hour, 3-5 tons of puffed aquatic feed, and shrimp and crab pellets. 1.5-2.5 tons of material. The process flow is: 2 2,000-ton raw material silos, 3 artificial raw material feeding ports, three primary crushing lines, three primary ingredient mixing lines (livestock and poultry feed, ruminant feed are independent batching systems, extruded feed, shrimp and crab feed are shared once Mixed batching system), two 420 pelleting lines (which can simultaneously produce livestock and poultry feed and ruminant feed; equipped with two sets of packaging systems and bulk systems), two ultra-fine crushing lines, two secondary mixing lines (expanded materials, Shrimp and crab material secondary independent batching system), a puffing line (supporting drying spray cooling and packaging system), a shrimp and crab pelletizing line (supporting stabilizer, vertical dryer, cooler, packaging and seedling shrimp material crushing line And other systems). The total power of the equipment is approximately: 2250KW; the construction area of the production area is approximately: 30.5*25*31m, with a 4T boiler. The whole line has compact design, reasonable structure, meets environmental protection requirements, and can be oriented design according to customer requirements.

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. A crusher can be selected after the cooler, especially in the production of poultry feed, the crusher can crush the finished large particles into small particles, improve production efficiency and reduce production costs;

4. The vertical dryer in the shrimp and crab material granulation section can be selected according to needs. If you do not produce large-sized crab material, you can ignore the use of the dryer.

Process characteristics and section introduction:

The various feeds produced by the project have different processing techniques such as crushing fineness and raw material maturation. In order to avoid cross-contamination, and to minimize the total investment in equipment and workshops, the project will design the four production lines in the same workshop Inside, the parts that can be shared are shared as much as possible, and the parts that cannot be shared are all separated independently. The specific sections and configurations are as follows:

Silo section:

Determine the size and quantity of the silo according to the customer’s storage cycle or material usage cycle. This process designs two 2000T steel silo (spiral silo) for storing corn. The silo type can also be made into an assembly silo according to customer requirements. All exposed parts of the silo are Do hot-dip galvanizing, and the support is concrete support (if the storage capacity is less than 1,000 tons, steel structure support can be considered). The silo is equipped with a material level, temperature measurement and ventilation system, which can monitor the material inside the silo in real time and effectively control the grain situation.

Livestock and poultry, ruminant pelletizing section:

This section uses 2 double-layer quenched and tempered granulators, which are dedicated to the production of livestock and poultry and ruminant materials. Each granulator is equipped with two granulating bins, which makes it easy to switch between varieties. After granulation, it enters the cooler, the crusher, and the elevator into the rotary grading sieve for screening. The finished product enters the packing bin, the powdered material is screened out and returned to granulation, and the large particles are screened out and returned to the crusher for crushing.

Granulating equipment (2 sets): SZLH420 (110KW), designed to produce 10-12T/H/set per hour. Cooling equipment (2 sets): SKLN6, designed to produce 10-15T/H/set per hour.

This section adopts a belt-driven shrimp pelletizing machine, in which the conditioner is equipped with a dual-shaft differential conditioner + a quality preserver + a jacketed conditioner, which effectively guarantees the pre-maturing requirements for pelleting. Two bins to be granulated are arranged above the machine. The finished product after granulation enters the stabilizer for post-curing treatment to improve the stability of the feed in the water; in order to solve the problem that the water content of the large-particle crab feed is likely to exceed the standard, this project specially adds a drying process, which comes out of the stabilizer. The particles enter the vertical dryer for drying to remove excess water, and then enter the cooler for cooling, and finally are lifted into the rotary grading screen for screening, and the finished product enters the packing bin.
