As an important source of edible oil in the world, the purchase of palm oil pressing equipment is directly related to the production efficiency and economic benefits. This article is based on industry practice and technical standards, combing the complete purchase process of palm oil presses, to provide practitioners with scientific decision-making reference.
I. Define the production demand and equipment type
Capacity planning
Small plantations or family workshops are recommended to choose single screw model, with a capacity of 300-500kg/h, suitable for initial investment or flexible operation.
Medium-sized processing plant can choose 1-5 tons / h double screw model, to support continuous production and reserve space for line expansion.
Large enterprises need to configure 5-15 tons/h equipment, supporting automatic control system and hydraulic adjustment function.
Process Adaptation
Cold pressing process retains more nutrients and is suitable for high-end market; hot pressing process has high oil yield and is suitable for large-scale production.
It is necessary to choose the pressing method according to the characteristics of raw materials, for example, African oil palm fruits need high temperature softening treatment, while Southeast Asian varieties may be suitable for low-temperature pressing.
Core equipment selection criteria
Comparison of technical parameters
Pressing efficiency: the double screw model adjusts the distance between the screws through the hydraulic system, and the oil yield is increased by 15%-20% compared with the single screw model.
Energy consumption control: high quality models are equipped with intelligent temperature control system, which can reduce power consumption by 10%-15%.
Material durability: The service life of the screw made of high strength martensitic stainless steel is 2-3 times longer than that of ordinary carbon steel.
Automation Configuration
Modern model integrates PLC control system, which can monitor pressure, temperature and other parameters in real time, and shorten the fault warning response time to within 30 seconds.
Equipped with automatic lubrication system, it reduces the frequency of manual maintenance and improves the continuous operation capability of the equipment.
C. Supplier Screening and Field Inspection
Qualification Audit Points
Verify whether the enterprise has ISO9001 quality management system certification and CE safety certification.
Requirements Provide similar equipment sales cases in the past three years, focusing on Southeast Asia, Africa and other major palm producing areas project experience.
On-site verification process
Observe the operation demonstration of the equipment, focusing on the following:
Oil and dregs separation effect during the pressing process, the percentage of oil output at the strip row should be more than 60%.
Cake quality, normal cake flakes should be flaky and the surface hairline is uniform.
Test the no-load starting current of the equipment, the normal value should be lower than 80% of the rated current.
Fourth, business negotiations and contract signing
Price Composition Analysis
The basic offer of the equipment usually contains the host, motor, control cabinet and other core components, need to specify the price of the hydraulic system, automatic cleaning device and other optional items.
Transportation costs need to be based on the weight of the equipment (1-5 tons / h model weighs about 3-8 tons) and transport distance is separately accounted for.
Confirmation of service terms
Warranty period is recommended to be not less than 12 months, key components (such as screws, bearings) need to be agreed separately extended warranty terms.
Installation and commissioning services should include on-site training to ensure that operators master equipment maintenance skills.
V. Acceptance and Post Maintenance
Acceptance Criteria for Arrival
Check whether the nameplate parameters of the equipment are consistent with the contract, focusing on checking the motor power, diameter of the screw and other core indicators.
Carry out trial operation with material, continuous production for more than 2 hours, and monitor the fluctuation range of oil yield should be controlled within ±2%.
Maintenance management specification
Establish daily inspection system, focusing on checking the wear and tear of the screw, and recommend replacing the lubricating oil every 500 hours.
Establish annual overhaul plan, including hydraulic system pressure calibration, electrical components aging test and other items.
The purchase of palm oil press machine needs to take into account the technical advancement and economic feasibility. Through scientific demand analysis, strict supplier screening and standardized acceptance process, the risk of equipment investment can be effectively reduced. It is recommended to prioritize the selection of suppliers with complete production line supporting capacity, so as to reserve space for subsequent capacity upgrading.
