The screw oil press operates on a simple yet efficient principle. As the sesame seeds are fed into the hopper, they are gradually pushed forward by the rotating screw shaft. During this process, the pressure increases, and the oil is squeezed out from the seeds. This continuous pushing and squeezing mechanism makes it highly suitable for continuous operation in sesame oil production. For example, in a medium - sized oil mill, a well - functioning screw oil press can process up to 500 kilograms of sesame seeds per hour, ensuring a steady supply of raw material for the continuous production line.
When compared with hydraulic oil presses, screw oil presses have several significant advantages. In terms of production capacity, a screw oil press can produce 3 - 5 times more oil per hour than a hydraulic oil press of the same size. This is mainly because the continuous operation of the screw oil press eliminates the need for repeated loading and unloading processes, which are common in hydraulic oil presses.
Efficiency is another area where screw oil presses shine. The automation of the screw oil press reduces the time required for each pressing cycle. It can complete a pressing process in just a few minutes, while a hydraulic oil press may take up to half an hour for the same amount of seeds. Moreover, the labor intensity is much lower with a screw oil press. Operators only need to monitor the machine and perform basic maintenance tasks, rather than manually operating the hydraulic system as in the case of hydraulic oil presses.
| Comparison Items | Screw Oil Press | Hydraulic Oil Press |
|---|---|---|
| Production Capacity (kg/h) | Up to 500 | 100 - 150 |
| Pressing Cycle Time | A few minutes | Up to half an hour |
| Labor Intensity | Low | High |
Screw oil presses are widely used in medium - to - large - sized oil mills and industrial production lines. In medium - sized oil mills, the continuous production capacity of the screw oil press can meet the daily demand of local markets. For industrial production lines, it can be integrated into a more complex system, ensuring high - volume and high - quality sesame oil production.
However, customers often face some pain points. For example, in some small - scale production environments, the initial investment in a screw oil press may seem relatively high. Also, in areas with limited technical support, operators may find it difficult to handle some complex operation and maintenance tasks.
During daily operation, screw oil presses may encounter several common faults. One of the most frequent issues is the jamming of the screw shaft. This can be caused by foreign objects in the seeds or excessive pressure due to over - feeding. To solve this problem, operators should check the raw materials carefully before feeding and adjust the feeding speed according to the machine's capacity.
Another common problem is the high oil content in the oil residue. This may be due to improper adjustment of the pressing parameters or wear and tear of the pressing parts. Operators can adjust the clearance between the screw shaft and the barrel and replace the worn - out parts in time. Temperature control failure is also a common headache. It can be addressed by regularly checking the temperature sensor and the cooling system.
Let's take a look at a real - world example. A medium - sized oil mill in a rural area used to rely on a hydraulic oil press. The daily production was limited to 200 liters of sesame oil, and the labor cost was relatively high. After switching to a screw oil press, the daily production increased to 800 liters, and the labor cost was reduced by 30%. The quality of the sesame oil also improved, as the continuous pressing process ensured a more uniform extraction of the oil.
To ensure the long - term stable operation of the screw oil press, regular maintenance is essential. This includes cleaning the machine after each use, lubricating the moving parts, and checking the electrical system. In addition, proper operator training is crucial. Well - trained operators can not only operate the machine more efficiently but also detect and solve potential problems in time, thereby reducing downtime and improving overall productivity.
