Soybean oil presses are crucial equipment in the oil - processing industry. However, common problems such as equipment clogging and oil impurities often plague users, affecting production efficiency and oil quality. In this article, we will delve into these issues, analyze them through real - world user cases, and provide practical prevention and maintenance strategies.
The causes of equipment clogging can be attributed to multiple factors. Firstly, improper cleaning of soybeans before pressing can lead to foreign matter entering the machine, causing blockages. Secondly, long - term use without regular maintenance can result in the accumulation of residues in the hopper, screw shaft, and pressing chamber, reducing the flow rate of materials and eventually causing clogs. As for oil impurities, they are mainly due to ineffective filtration systems and improper operation during the pressing process.
These problems have a significant impact on production. Equipment clogs can lead to a sharp decline in production efficiency, with some users reporting a 30% - 50% drop in daily output. Oil impurities not only affect the quality of the oil but also reduce its market competitiveness, potentially leading to a 20% - 30% decrease in product price.
Proper cleaning and preparation of soybeans are the first steps in preventing equipment clogs and oil impurities. Before pressing, soybeans should be screened to remove stones, soil, and other foreign matter. This can be achieved through a vibrating screen or a gravity separator. Additionally, soybeans should be dried to an appropriate moisture content, usually between 10% - 12%. Incorrect moisture content can affect the pressing process and increase the likelihood of clogs.
The hopper and pressing machine need to work in harmony to ensure smooth operation. Regularly check the hopper for blockages and clean it at least once a week. Ensure that the feed rate is uniform to prevent over - feeding, which can cause clogs. For the pressing machine, pay attention to the alignment of components and the tightness of bolts. Any loose parts should be tightened promptly.
The screw shaft and pressing chamber are the core components of the oil press. They require regular lubrication and cleaning. Use high - quality lubricants to reduce friction and wear. Clean the screw shaft and pressing chamber after each use to remove residual oil and debris. This can significantly extend the service life of these components, with some users reporting an increase in equipment lifespan by up to 2 - 3 years.
The filtration system is key to ensuring oil purity. Regularly clean the filter screens to prevent blockages. Replace filter elements every 1 - 2 months, depending on usage. A well - maintained filtration system can reduce oil impurities by more than 80%, ensuring high - quality oil production.
Let's look at a real - world case. A user reported a sudden drop in production efficiency and an increase in oil impurities. Through on - site inspection, it was found that the hopper was clogged, and the filter screen was severely blocked. After cleaning the hopper and replacing the filter screen, the equipment returned to normal operation, and the oil quality improved significantly.
When troubleshooting, follow a systematic approach. First, visually inspect the equipment for obvious blockages or damage. Then, check the operation parameters such as feed rate, temperature, and pressure. If necessary, disassemble relevant components for in - depth inspection.
Preventive maintenance is crucial for the long - term operation of soybean oil presses. Establish a regular inspection and maintenance schedule, including daily, weekly, and monthly checks. This can not only reduce the occurrence of failures but also improve equipment performance and extend its service life.
