Embodiment Construction

[0006] combine figure 1 , the production process of the present invention will be described in further detail below.

[0007] 1. Cleaning of raw materials: Sieve through a vibrating flat sieve with suction, and equipped with an iron suction device, mainly to remove impurities such as marl, sand, rope ends, and iron filings.

[0008] 2. Cold pressing: use the X-10 automatic screw oil press, and the pressing screw needs to be adjusted. The compression ratio curve can refer to the curve of rice bran pressing, and the whole sesame is directly put into the press for cold pressing, and the oil output efficiency is required to be 75-80. %.

[0009] 3. Extraction: The cold-pressed cake is transported to the extraction workshop, and extracted with a horizontal extractor, and the operation is the same as that of ordinary oil cake.

[0010] 4. Filtration: Combine cold-pressed crude oil and extracted oil (can also be processed separately), filter with plate and frame filter press, filte...

Abstract

The invention discloses a novel process for alkali refining of gap type grease. The process flow of the invention is as follows: material cleaning, cold press, leaching, filtering, decoloring, re-filtering, alkali refining, vacuum dewatering and polishing; and proper quantity of additives taking polar solvents as a main material are added in the alkali refining procedure, so as to make the soap solution to be relatively stable emulsion and further make the separation of the grease and the soap more fast and complete.

Description

technical field [0001] The invention relates to an industrial production and refining technology of oil, in particular to a new intermittent oil alkali refining process. Background technique [0002] There are currently four types of process combinations for animal and vegetable oil refining, namely physical refining, mixed oil refining, continuous refining, and intermittent refining (commonly known as cylinder refining). In China, except that the refining of mixed oil has not been applied in large-scale production, the other three process combinations are all used in production. According to statistics, there are more than 3,500 oil production enterprises in my country, among which five are large-scale enterprises (more than 6,000 tons of oil are processed daily), and the rest are small and medium-sized enterprises, accounting for more than 95% of the national oil production. Most of them are produced by intermittent refining. Although batch refining is an ancient producti...
