Development status of nut material shelling technology (2)

Development status of nut material shelling technology (2)
At present, the typical nut sheller in China has:
(1) Apricot kernel shelling machine: Domestic research and development of apricot kernel shelling is relatively more than that of other nuts shelling. Among them, the 5XJC-350 type almond processing equipment researched and developed by China Agricultural Machinery Institute is more representative.
The device uses a grooved roll sheller to break the shell in the thickness direction. The complete equipment includes grading system, shell breaking system, cleaning and gravity sorting system, inlet and outlet system, dust removal system, conveying system and control system.
The apricot kernels are first removed from the empty machine by the gravity sorter and then enter the classifier. They are divided into 6 grades according to the thickness; they are respectively crushed by 6 shell breakers with different shell gaps; the crushed mixture is then cleaned. The machine separates the slag and the unbroken apricot kernel; finally, the two shells are separated by two gravity sorters. The apricot kernel stripping rate of the equipment is 93%, the almond breaking rate is 5.7%, the degree of automation is high, and the operation is convenient; meanwhile, the working environment has been significantly improved due to centralized dust removal.

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...
