Problems solved by technology

At present, the production of domestic cottonseed oil is mostly backward, and there are defects such as small production scale, backward technology, outdated equipment and equipment, low profit, and low added value. Some backward areas still use the pressing method, and the cottonseed has not been shelled and processed. Delinting, high residual oil, and no use of cotton shells and lint, some manufacturers use pre-pressing leaching, equipment investment is relatively large, the process route is monotonous, equipment utilization rate is not high, and lack of modern market competitiveness

Embodiment 1

[0026] Cotton seeds are peeled and shelled to obtain cotton kernels, which are softened in a softening pot at a temperature of 70°C until the water content of the cotton kernels is 11%; flaking with a flaking machine at a pressure of 6Mpa Left and right, the thickness of the embryo sheet is 0.45mm; then it is sent to the extruder for puffing treatment, the pressure of the high-pressure steam of direct steam is 0.6MPa, the pressure of high-pressure steam of indirect steam is 0.5MPa, the temperature of puffing is 115°C, and the water content of the output is 12%, then dried to a water content of 10%, and finally leached with hexane, the material level accounted for 70% of the material grid capacity, the volume ratio of solvent to immersion oil was 0.9, the leaching time was about 75 minutes, and the immersion temperature was At about 55°C, cottonseed mixed oil is obtained. The residual oil of the wet meal is less than 0.5%, and the color is bright yellow.

Embodiment 2

[0028] Cottonseeds are peeled and shelled to obtain cotton kernels, which are softened in a softening pot at a temperature of 65°C until the moisture content of the cotton kernels is 10%; flaking is performed with a flaking machine, and the pressure of the flaking is 6Mpa Left and right, the thickness of the embryo sheet is 0.35mm; then it is sent to the extruder for puffing treatment, the pressure of the high-pressure steam of direct steam is 0.65MPa, the pressure of high-pressure steam of indirect steam is 0.55MPa, the temperature of puffing is 110°C, and the water content of the output is 11%, and finally leached with hexane, the material level accounted for 60% of the capacity of the material grid, the volume ratio of the solvent to the immersion oil was 0.8, the leaching time was about 65 minutes, and the immersion temperature was about 55°C to obtain cottonseed mixture Oil. The leaching effect is excellent, the residual oil of the wet meal is generally below 0.5%, and th...

Embodiment 3

[0030] Cottonseeds are peeled and shelled to obtain cotton kernels, which are sent to a buffer box, which is equipped with a magnetic separator to realize automatic iron absorption and iron removal, and then the cotton kernels are softened in a softening pot. 65°C, soften until the moisture content of the cotton kernel is 11%; flaking with a flaking machine, the pressure of the flaking is about 6Mpa, and the thickness of the embryo sheet is 0.40mm; At 0.63MPa, the pressure of high-pressure steam of indirect steam is 0.52MPa, the temperature of puffing is 112°C, the water content of the discharged material is 12%, and then dried to a water content of 11%, and finally leached with hexane, the material level occupies the material grid 65% of the capacity, the volume ratio of the solvent to the immersion oil is 0.7, the leaching time is about 70 minutes, and the immersion temperature is about 55°C to obtain cottonseed mixed oil. The leaching effect is excellent, the residual oil o...

Abstract

The invention relates to a cotton seed oil mixture manufacturing method by straight leaching. It adopts parts of soybean preprocessing line to make cotton kernel soften, expanding after flaking, and process straight leaching without pre-squeezing and dust removal systems. It has the advantages of little investment and good effect. The phenol content of the post-leaching liberation cotton is less than 0.12%. And the residual oil of the cake is less than 0.5%.

Description

Technical field: [0001] The invention belongs to the field of grain and oil processing, and relates to a production method of cottonseed oil, in particular to the production of cottonseed oil by adopting the cotton kernel direct extraction technology. Background technique: [0002] Cotton is one of the main economic crops in my country, and its output ranks first in the world. With the deepening of the reform of China's cotton circulation system, liberalization of cotton purchases and vigorous promotion of cotton industrialization management, my country's cotton processing industry is facing a profound historical change and unprecedented development opportunities. [0003] Cottonseed is the seed of the cotton crop. Whole cottonseed contains 15% to 25% oil, cotton kernel contains 32% to 46% oil, and contains about 30% protein. It is an important oil resource and plant protein resource. In recent years, with the rapid growth of China's demand for oil consumption, the market ...
