I. Customer Background and Core Challenges
Our customer is a large edible oil refining enterprise in East China, whose product line includes the refined processing of various vegetable oils. After the decolorization stage in the refining process, a filtering device is required to completely separate the decolorizing agent used to absorb pigments and impurities from the hot oil, in order to obtain clear and transparent finished oil.
They have long been using traditional plate-and-frame filters, but they are facing numerous problems:
The operation is cumbersome: It relies on a large number of filter cloths, and each batch of operation requires manual loading, unloading and cleaning, which results in extremely high labor intensity.
The environment is worrying: The sealing is poor, and the hot oil vapor evaporates, resulting in an extremely greasy environment in the workshop, posing safety and hygiene risks.
High cost: The filter cloth has a significant loss, and the residual rate of the oil in the filter cloth is high, resulting in considerable product loss and waste of auxiliary materials.
Low efficiency: The entire filtration and slag removal cycle is too long, failing to meet the expansion requirements for continuous production.
II. Our Solution
After conducting in-depth research on their production process, we recommended and installed a vertical closed-leaf filtration system for them, which effectively addressed all the aforementioned issues.
No need for filter cloth technology: By using pre-coated filter aid technology, only a small amount of food-grade filter aids are required to form a stable filter layer. This completely eliminates the need for filter cloth consumption and cleaning.
Fully sealed design: During the entire process of filtration, drying and discharging, the equipment remains completely sealed, preventing the volatilization of oil vapor. This significantly improves the workshop environment and ensures production safety and food hygiene.
Automated operation: Using a PLC control system, the process from filtration, drying to discharging has been fully automated. Workers only need to press the buttons, and the equipment can automatically complete the entire process, significantly reducing the labor intensity.
Efficient Recovery: The unique vertical vibration discharge design ensures a thorough removal of the filter cake, significantly reducing the residual rate of oil in the waste residue and directly increasing the product yield.
III. Significant Value Added to Customers
Since the new equipment was put into operation, customers have achieved immediate benefits in multiple aspects:
Significant improvement in economic benefits:
The continuous costs of purchasing and handling the filter cloth have been completely eliminated.
The oil recovery rate has been increased, thereby reducing the loss of valuable materials.
Automated operations have reduced the amount of manual labor required.
Production efficiency has significantly improved:
The filtration cycle is shortened and the equipment’s processing capacity is enhanced.
The automated operation has made the batch connection more smooth, meeting the demand for expansion production.
Fundamental improvement in environment and safety:
The workshop has become clean and tidy, with no more oil stains or steam.
The fully enclosed production process eliminates potential safety hazards and easily passes the environmental protection and food safety production audits.
Product quality is stable and reliable:
The stable filtration pressure and efficient cleaning function ensure that every batch of the produced lubricating oil is clear and transparent, with consistent quality.
IV. Customer Evaluation
“This vertical blade filter has completely transformed our production workshop. It is not merely a piece of equipment; it represents a significant upgrade in our production method. Now, we no longer see greasy floors and workers constantly moving filter cloths back and forth. The workshop is cleaner, costs have decreased, efficiency has increased, and management has become much easier. It has completely replaced the original plate and frame machine and is one of the most successful upgraded equipment on our production line.”
