Microwave vacuum drying of roses

In order to improve the quality of dried rose flowers, reduce drying time. The company dried the roses by microwave vacuum drying equipment and compared the effects of different vacuum and microwave power on the quality of dried rose flowers.
The research results show that the higher the degree of vacuum, the faster the water transpiration in the material and the faster the drying, the lower the temperature rise of the material.

As the microwave power increases, the drying time is greatly shortened.
Industrial continuous red rose flower microwave drying machine
Considering the dry time, temperature, morphological change and color of dried rose flowers, compared with hot air drying, microwave vacuum drying process with vacuum degree of 0.10 MPa, microwave power of 200 W and drying time of 80 min is suitable for drying conditions. The research results provide a theoretical basis for the drying and industrial production of roses.
Rose, also known as red rose, is a genus of Rosaceae, perennial deciduous shrub, thorny stems, flowers with red, purple, white, yellow, powder and other colors. Roses are mainly grown in temperate zones and are native to central and eastern Asia. They are distributed in North China, Northwest and Southwest China, Japan, North Korea, North Africa, Mexico, and India. They are also widely grown in many other countries. They are excellent flower shrubs. It is also an important spice plant.

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...
