Edible oil industry
Plate-and-shell heat exchanger: Main focus Precise temperature control, process‑stage heating/cooling It is compatible with key process stages such as crude oil pretreatment, degumming, alkali refining, and decolorization, offering high heat‑exchange efficiency and precise temperature control, thereby reliably meeting the exact temperature requirements of various edible‑oil processing steps.
Refrigeration equipment interlock Industrial chillers combined with dedicated refrigeration units, storage tanks, and cooling towers provide a stable cold supply to heat-exchange equipment throughout the process, while directly maintaining low‑temperature conditions for oil fractionation and finished‑product storage. This approach prevents oxidation, rancidity, and fractionation failure at the source, meeting the quality‑control and storage‑transport standards for various edible oils.
| Production stage | Heat exchange equipment | Refrigeration equipment | Function |
| Crude Oil Pre-treatment Section | Plate-and-shell heat exchanger | Industrial chiller | 1. Rapid temperature control of crude oil after pressing or solvent extraction to inhibit early oxidative rancidity; 2. Precise preheating and temperature regulation for subsequent refining steps, aligning with process temperature requirements and enhancing pretreatment efficiency. |
| Refining – Degumming / Alkali Refining Section | Plate heat exchanger | Chiller + Refrigeration Circulation System | 1. Recovers heat from crude oil and precisely heats it to the degumming and neutralization process temperature (85–95°C); 2. Maintains constant temperature in the water-washing stage following alkali refining, with a chiller ensuring stable water temperature to efficiently remove residual soap, phospholipids, and impurities. |
| Refining – Decolorization Section | Plate-and-shell heat exchanger | Vacuum Drying Refrigeration Unit | 1. Heat the degummed oil to a decolorization temperature of 105–115°C, ensuring stable heat exchange without localized overheating; 2. Employ an integrated refrigeration system to achieve rapid vacuum dehydration, thereby preventing re‑moisturization, oxidation, and color reversion of the decolorized oil. |
| Refining – Deodorization Section | Plate-and-shell heat exchanger | Industrial chiller | 1. Efficiently recovers the heat from decolorized oil and deodorized finished oil, significantly reducing production energy consumption; 2. Heats the decolorized oil to a deodorization temperature of 230–260°C, with precise temperature control to remove free fatty acids and volatile compounds; 3. After deodorization, the finished oil is rapidly cooled to 80–85°C and further cooled to below 50°C to prevent secondary oxidation. |
| Fat Fractionation Section | Plate-and-shell heat exchanger + spiral plate heat exchanger | Cryogenic refrigeration unit + refrigeration storage tank | 1. Two heat exchangers work in tandem to precisely control the cooling and crystallization temperature of fats, meeting the fractionation requirements for different melting points. 2. A low-temperature refrigeration unit maintains a stable crystallization environment, efficiently separating soft fats from hard fats to ensure high fractionation purity and product quality. |
| Finished Goods Storage Section | Spiral plate heat exchanger | Refrigeration oil storage tank + constant-temperature refrigeration system | 1. The heat exchanger assists in regulating the oil temperature in storage tanks, ensuring compliance with varying temperature standards for the storage and transportation of different oils and fats. 2. Constant‑temperature refrigeration maintains the desired storage temperature, preventing oxidation, rancidity, and crystallization, thereby preserving product quality and extending shelf life. |
| Full-process specialty oil processing | Plate-and-shell heat exchanger + spiral plate heat exchanger | Industrial chiller + vacuum refrigeration equipment | It supports full-process temperature control for degumming, decolorization, and deodorization of high-viscosity and specialty oils such as palm kernel oil and coconut oil; its wide flow channels are resistant to clogging, while the refrigeration system ensures low-temperature preservation and precise temperature regulation across all process stages. |
| Plant-wide Heat Recovery / Supporting Systems | Plate-and-shell heat exchanger + spiral plate heat exchanger | Chiller + Cooling Tower | 1. Recover and reuse waste heat from the entire workshop to achieve energy savings and reduced consumption; 2. Provide a continuous, stable cooling supply to all heat-exchange equipment, ensuring the edible‑oil production line operates continuously, efficiently, and reliably. |
