3-5T/H Pig Feed Production Line In Bolivia

Process design of pig feed mill plant in Bolivia

This pig feed production line in Bolivia adopts the innovative process of "crushing-expansion-mixing-granulation-cooling", which organically combines traditional feed processing with single-screw raw grain extrusion technology to form a unique process advantage.

1. The raw materials are first processed by a hammer mill to reach a particle size suitable for subsequent processing (pig feed usually requires 1-2mm). The crushed grain raw materials enter the single-screw extruder to complete the starch gelatinization process under high temperature and high pressure.
2. The single screw system is stable and easy to maintain, which is particularly suitable for the local technical conditions in Bolivia. The expanded material is fully mixed with protein raw materials, premixes, etc. in the customer's existing mixer to ensure uniform distribution of nutrients.
3. The mixed material enters the SZLH320 ring die pig feed pellet machine for pressing and molding. The pelletizing process parameters are carefully adjusted according to the characteristics of the formula to ensure that the pellet hardness is moderate (pig feed usually requires 8-10N) and the durability index reaches more than 95%.
4. The hot pellets just extruded from the ring die immediately enter the countercurrent cooling system to quickly cool down and reduce the moisture content. The moisture content of the final product is controlled below 12%.

The highlights of the process include:

• The single-screw grain extruder system is easy to operate and suitable for the level of local technicians
• The extrusion process improves starch digestibility by 12-15%
• Energy utilization is optimized and the power consumption per ton is reduced by 10%
• The modular layout facilitates future expansion

equipment for Bolivia pig feed plant project

The selection of core equipment for the pig feed production line in Bolivia focuses on the balance between technical practicality and economy, and perfectly adapts to local conditions in Bolivia:

1. Crushing equipment: SFSP56 series water-drop type crusher, equipped with a 45kW motor, with a processing capacity of 5-6 tons/hour. Special wear-resistant hammer design, suitable for a variety of grain raw materials.
2. Extrusion system: single screw grain extruder (main engine power 45kW), equipped with a simple temperature control system and a standard die head. The starch gelatinization degree can reach 75-85%, meeting the basic requirements of pig feed.
3. Granulation equipment: SZLH320 ring die feed pellet machine, main motor 75kW, standard 4.5mm aperture ring die (replaceable). Equipped with manual lubrication system and overload protection.
4. Cooling equipment: SKLN120 counter-current cooler, processing capacity 5 tons/hour. Equipped with simple control panel and temperature indicator.

Auxiliary equipment:

• Screw conveying system (diameter 300mm)
• Bucket elevator (TDTG36/18)
• Pulse dust collector
• Electric control system (basic PLC control)

The voltage of the whole pig feed production line in Bolivia adapts to 380V three-phase electricity. The design takes into account the fluctuation of the local power grid (±10%). The key components are made of wear-resistant materials to reduce maintenance requirements. The equipment layout is compact and covers an area of ​​about 200 square meters.

Project Features

This pig animal feed production line has many outstanding features, making it a benchmark project in Bolivia's pig farming industry. The most notable feature is the use of a single-screw extruder system. Compared with the more complex twin-screw system, although the gelatinization degree is slightly lower, the investment and maintenance costs are greatly reduced, which is more suitable for local technical conditions and budget levels.

Actual operation data shows that the single-screw system can fully meet the basic gelatinization requirements of pig feed, the starch digestibility is increased by 12-15%, and the equipment failure rate is only 60% of the industry average.

From the perspective of economic benefits, the project has a satisfactory return on investment. Compared with purchased feed, self-produced extruded pellet feed can reduce the cost per ton by about US$80. Based on the current breeding scale, the annual cost savings exceed US$150,000, and the investment payback period is controlled within 18 months. At the same time, the improvement of feed quality has reduced the feed-to-meat ratio from 2.8 to 2.6, further increasing the breeding benefits.

In terms of adaptability, the design of the pig feed production line in Bolivia fully considers the actual situation in Bolivia:

• The operation interface is simple and intuitive, which is easy for local workers to master
• The equipment is sturdy and durable, and can adapt to high temperature and high humidity environments
• Spare parts are highly versatile and available in the local market
• Energy consumption levels are optimized to adapt to power supply conditions

It is particularly worth mentioning that the pig feed production line in Bolivia retains the traditional granulation process channel. When the extrusion process is not required, it can be directly crushed and granulated. This flexibility greatly improves the utilization rate and economy of the equipment.

Project prospects

This pig feed production line in Bolivia combined with single-screw extrusion technology has broad development space in Bolivia and similar regions. As one of the fastest growing pork consumption countries in South America, Bolivia's pork self-sufficiency rate is only about 65%, and there is huge potential for development. The government has listed local feed production as a priority for animal husbandry development and provided a number of supporting policies:

• Tariff reduction on equipment imports (from 10% to 2%)
• Agricultural technology extension services
• Farm modernization subsidies
• Technician training program

Market trends are also encouraging. As consumers' requirements for pork quality increase, the demand for high-quality feed using extrusion technology will continue to grow. In the future, the customer can consider:

• Adding functional additives (such as probiotics)
• Developing phased special feed
• Introducing intelligent control systems
• Expanding to other livestock and poultry feed production

Potential market opportunities include:

• Processing services for small farms in the surrounding area
• Special feed for special pig breeds
• Organic certified feed products
• Functional health feed

The success of this pig feed production line in Bolivia project proves that through appropriate technological innovation and equipment selection, even a single-screw extruder system can significantly improve feed quality and breeding benefits. For countries like Bolivia that are developing intensive breeding, this economical and practical technical solution has important promotion value.

It is expected that similar projects will be rapidly popularized in the Andes region in the next five years and become an important force in promoting the modernization of animal husbandry.
