Embodiment Construction

[0009] Accompanying drawing shows the process flow of the extraction method of dephenolized cottonseed protein of the present invention, after the pretreated flakes are sent into the extractor, the cottonseed oil is first sprayed and extracted with a non-polar solvent to obtain a mixed oil, and the mixed oil is obtained after evaporation Crude oil; then spray and extract gossypol with a polar solvent in the extractor to obtain a mixed phenol solution, and the mixed phenol solution is rectified to obtain a gossypol concentrated solution; the dephenolized wet billet separated from the extractor is first sent to the drying The dryer is then sent to the conditioner, and then cooled to obtain the finished cottonseed protein. The specific process is as follows: After the wool cottonseed after the ginning process is delinted by a delint machine, the short fluff on the surface of the wool cottonseed is removed to obtain light seeds, and the light seeds are peeled by a sheller and then...

Abstract

The invention discloses an extraction method of the dephenolized cottonseed protein, with the rough piece of the cotton kernel after doffing the cashmere, shelling, adjusting the quality, rolling and drying as the raw material; the polar and non-polar solvents are used as the extraction reagents; concentrated in a container, the raw material is continuously added and the two extraction reagents are continuously added in the divided steps; after the low-temperature extraction and separation, the mixed oil, mixed phenol solution and wet meal can be got; the mixed oil can be made into the rough cotton oil after the wholly negative-pressure evaporation and concentration; the mixed phenol solution can be made into the gossypol concentrated liquid after the vacuum distillation and concentration; the wet meal can be made into the dephenolized cottonseed protein after doffing the cashmere and adjusting the quality. The technological route of the invention is simple; the occupied area of the equipment is small; the one-time comprehensive investment is less; the running and leakage of the negative pressure in the whole system is less; the production cost is low; the product quality is guaranteed; the invention reduces the three-waste emission and is suitable for the industrialized mass production.

Description

technical field [0001] The invention relates to a deep processing method of cottonseed, and directly relates to a method for preparing dephenolized cottonseed protein. Background technique [0002] China is a big cotton-producing country in the world. In 2006, the output of cottonseed alone reached 11 million tons. After separation and processing, 4.4 million tons of cottonseed meal can be obtained. The nutritional value of cottonseed protein is close to that of soybean protein, and it is a good protein. Feed resources can be used to replace fish meal and soybean meal, etc., and the price of cotton meal is much lower than that of soybean meal and fish meal. Therefore, the application of cottonseed protein has a strong competitive advantage, and the market development prospect is broad. However, ordinary cottonseed meal contains a high amount of free gossypol. When used as feed, it will cause harm to the liver and male reproductive system of livestock and poultry, and will...
