1–10 TPD Small-Scale Palm Oil Refining Equipment: Huatai Enhances Quality and Efficiency through Degumming, Deacidification, and Bleaching
For small-scale palm oil processing plants or on-site primary processing projects, the ability to refine crude palm oil into food-grade oil that meets national standards—while keeping investment costs manageable—is the key factor determining market value. The 1–10 TPD small-scale palm oil refining equipment is a solution tailored specifically to this need, focusing on the core processes of degumming, deacidification, and bleaching. As a leading enterprise in China’s grain and oil machinery sector, Henan Huatai Cereals & Oils Machinery Co., Ltd. provides mature, reliable batch refining equipment and process support for this capacity range.
1. Why Does Crude Palm Oil Require Refining?
Crude palm oil (CPO)—freshly obtained from pressing—contains impurities such as phospholipids, free fatty acids, pigments, and trace metals. If consumed directly, it suffers from poor flavor and low stability. The purpose of refining is to systematically remove these quality-impairing components using physical and chemical methods. The typical refining process comprises four main stages: degumming, deacidification, bleaching, and deodorization. The first three stages directly determine the workload of the subsequent deodorization process and the quality of the finished oil.
For small-scale projects with a daily processing capacity of 1–10 tons, the equipment configuration typically utilizes a batch refining method. This integrates degumming, bleaching, and deodorization tanks into a single system equipped with vacuum units and filtration devices, offering the advantages of low initial investment, operational flexibility, and a compact footprint.
Analysis of Core Processes: Degumming, Deacidification, and Bleaching
1) Degumming
Degumming aims to remove colloidal impurities—such as phospholipids, gums, and proteins—from the crude oil. If not removed beforehand, these substances can carbonize during subsequent high-temperature processing, negatively affecting the oil’s color and flavor. For crude palm oil, acid degumming or hydration degumming processes are commonly used. Phosphoric acid or citric acid solution is added to convert non-hydratable phospholipids into a hydratable form, which is then removed via centrifugation or sedimentation. Henan Huatai’s small-scale palm oil refining equipment features temperature-controlled agitation and metered dosing systems in the degumming stage, ensuring thorough gum coagulation and separation.
2) Deacidification
Deacidification is a critical step in palm oil refining. Crude palm oil often has a high free fatty acid content, which must be reduced to a safe level. Alkali refining is a common method for batch processing: a specific amount of sodium hydroxide solution is added to the oil to neutralize free fatty acids and form soapstock, which is then removed via static settling or centrifugal separation. For small-scale palm oil refining production lines (1–10 TPD), the alkali refining process offers significant operational flexibility, accommodating crude palm oil feedstocks with varying acid values. Henan Huatai’s palm oil refining equipment design emphasizes precise alkali dosing and easy soapstock separation, helping operators minimize refining losses.
3) Bleaching
The bleaching process utilizes the adsorption properties of activated bleaching earth to remove pigments—such as chlorophyll and carotenoids—from the oil, while simultaneously adsorbing trace amounts of residual soap, metal ions, and peroxides. During operation, the oil is heated to a specific temperature and thoroughly mixed with the bleaching earth under a vacuum; the spent bleaching earth is subsequently separated using a leaf filter. The resulting refined palm oil boasts a clear, bright color and enhanced stability, meeting the visual standards required for commercial edible oil products.
Henan Huatai’s Technical Capabilities
Henan Huatai Cereals & Oils Machinery Co., Ltd. is a national-level “Little Giant” enterprise (recognized for specialization, refinement, uniqueness, and innovation) with deep technical expertise in the oil and fat machinery sector.
