Development Status of Shelling Technology for Nut Materials (3)

Development Status of Shelling Technology for Nut Materials (3)
(3) Pine seed sheller: The most representative of pine seed shelling is the SZ-1 type pine seed sheller developed by the Northeast Heavy Machinery Institute. The machine has the characteristics of high pine nut integrity rate (up to 99.3%), high productivity, small size, light weight, low energy consumption and good sanitary conditions. It uses a pair of rolling rollers that move in opposite directions to break the hard shell of the pine nuts. The rolling roller consists of several rolling wheels.
The surface of the wheel is machined into an annular circular groove, and a plurality of small triangular small grooves are added to the surface of each groove. The arc table grooves of the two corresponding wheels constitute an elliptical hole type, and the long axis thereof is parallel to the axis of the rolling wheel. A pine seed guide positioning device is mounted on the upper portion of the two relatively slewing rollers.
The pine nuts continue to rotate while sliding. When the rolling roller continues to rotate relative to each other, the two sides of the pine seed are instantaneously squeezed and exploded, and the skin is broken and the kernel is intact, and the shelling process is completed. The machine can also shell the hazelnut and apricot kernels, and the integrity of the nuts is over 98%.
(4) Chestnut shelling machine: The chestnut shelling machine has two types of rollers - concave plate and cutter plate. Roller - The most critical part of the concave plate sheller is the scratch. The machine is equipped with a set of serrated disc cutters of equal spacing (about the size of the chestnut) on the raw material feed roller. When the feeding roller rotates, the chestnut is brought into the work area, and after the crack is applied to the outer casing, it is sent to the peeling area.

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...
