Dry-process alkali refining agent of edible oil and preparation and use methods for dry-process alkali refining agent

Abstract

The invention relates to a dry-process alkali refining agent of edible oil and preparation and use methods for the dry-process alkali refining agent. The dry-process alkali refining agent of edible oil is prepared through modifying silicon dioxide, Al2O3, Fe2O3 and water-soluble alkali, which serve as raw materials, with a di-oxidating agent and then mixing the modified materials with other raw materials. The dry-process alkali refining agent of edible oil and the preparation and use methods for the dry-process alkali refining agent have the beneficial effects that the dry-process alkali refining agent of edible oil, disclosed by the invention, is mainly applied to deacidification of refined salad oil and paste cooking oil and more applicable to deacidification of fats and oils with high acid number; the dry-process alkali refining agent is more environmentally friendly and more energy-saving; the dry-process alkali refining agent has the characteristics that no sewage is drained, newpollution to environments cannot be caused, the oil loss is low, the energy consumption is low, a water washing procedure during application operation is saved, the production process is simplified, the operation is facilitated, and the like; and by applying the dry-process alkali refining agent of edible oil, disclosed by the invention, the quality of the edible oil can be improved obviously.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, and in particular relates to an edible oil dry alkali refining agent, a preparation method and a use method thereof. Background technique [0002] With the progress of society, people's consumption concepts are also changing, and health has become one of the criteria for measuring people's diet consumption. In recent years, the consumption of high-grade oils in my country has shown an obvious upward trend, and salad oils and blended oils of various brands are constantly flocking to the market. However, the edible oil industry generally adopts the traditional water alkali refining process to deacidify the crude oil. This process must rinse the crude oil three times, and then perform centrifugation to achieve the deacidification effect. Not only the operation is complicated, but also the edible oil The water content is large; in the refining process, a large amount of acid-containing...

However, the edible oil industry generally adopts the traditional water alkali refining process to deacidify the crude oil. This process must rinse the crude oil three times, and then perform centrifugation to achieve the deacidification effect. Not only the operation is complicated, but also the edible oil High water content; in the refining process, a large amount of acid-containing oily wastewater will be discharged, causing serious environmental pollution. The country spends huge sums of money every year to treat industrial wastewater from the oil industry
