Study on Extraction of raw coconut oil by vacuum microwave method

Coconut oil is a vegetable oil extracted from mature coconut meat. The original coconut oil is a natural oil extracted from fresh coconut meat by green method. Rich in medium-chain fatty acids, it can be quickly digested and absorbed, and has a positive effect on the human body, so it is widely used in food and daily chemical industry and other fields. 
There are many ways to extract oils and fats, but there are many disadvantages in traditional methods. The coconut oil extracted by dry pressing has dark color and poor quality, while the coconut oil extracted by cold pressing has low extraction rate and high moisture content, which is not conducive to the preservation of coconut oil. Organic solvent extraction not only costs much, but also pollutes the environment and is harmful to human health.

Microwave drying machinery technology for oil extraction is a new green extraction technology. Coconut oil machine has been applied to extract edible oil, but there are few studies on coconut oil extraction. According to the research progress abroad, the quality of extraction is better, but the extraction rate is not high; domestic research on extraction technology is rare, and the extraction rate is not high, so the quality of extraction is not good. Therefore, more in-depth experimental research is needed to provide theoretical basis for improving the yield and quality.

Application of Camellia Seed Oil in Cosmetics Industry

图片
Before the advent of modern cosmetics, camellia seed oil was used as a traditional skin care hair care product in East Asia to improve the moisturization, smoothness and elasticity of skin and hair. Camellia saponin contained in camellia seed oil is a non-toxic surfactant with antioxidant activity and can be applied to advanced washing products. Compared with traditional surfactants, tea saponin has the advantages of being degradable, non-polluting and non-toxic, and is a natural active agent. Camellia seed oil can also be used to make cleansing oil with a very mild effect. Microwave drying machine Cosmetic grade camellia seed oil is mainly produced by low temperature and high pressure process. It is often used as a high-end cosmetic raw material or as a massage base oil, and is widely welcomed in domestic and foreign markets. Application of Camellia Seed Oil in Cosmetics Industry

Research on Hydraulic Pump Control Technology

图片
1 blade control technology The high-pressure energy-saving hydraulic vane pump controls the vane through the electric signal and the pilot hydraulic oil, and uses the solenoid valve to control the pilot oil to pass through the rear distribution disc, leads to the outside of the propeller shaft, and finally flows into the vane pump rotor, the pump shaft, and the vane locking mechanism.  hydraulic vane pump   The pilot hydraulic oil acts on the slide valve to press a small steel ball into the concave surface of the blade. The blade is completely locked in the blade groove of the rotor, and the sealing volume cannot be formed between the blade, the stator, the rotor and the oil distribution plate, and the blade card The pump is idling, thus stopping the vane pump oil supply cycle, reducing the drive or engine output power, and saving energy. The high pressure energy-saving vane pump is stuck in the rotor when the system does not require flow and pressure. When ...

Microwave vacuum drying of banana slices

图片
The microwave vacuum drying equipment technology was used to develop new banana drying products, and the optimum microwave vacuum drying technology for banana slices was obtained. microwave vacuum drying   The effects of vacuum, microwave intensity and slice thickness on color difference, brittleness, swelling rate and sensory quality of banana slices were studied by three factors and three levels L9 (34) orthogonal design. The technological parameters of microwave vacuum drying of banana slices were optimized by comprehensive optimization method. The quality of dried banana slices obtained by different microwave vacuum drying process parameters is obviously different. The optimum point of microwave vacuum drying process is determined as follows: vacuum degree - 80 kPa, microwave intensity 14 W/g, slice thickness 12 mm. The quality of dried banana slices obtained under this process condition is better than that of microwave drying. And vacuum frying. It is fea...
