Ultrafast optical metrology test technology research laboratory passed acceptance

[China Instrument Network Instrument R&D] On March 23, the “Ultrafast Optical Metrology Test Technology Research Laboratory” passed the acceptance. The establishment of this project provides effective technical support for the research of optical metrology test technology in China.

The “Ultrafast Optical Metrology Test Technology Research Laboratory Construction” is undertaken by the Zhejiang Provincial Metrology Institute and is a scientific and technological plan project in Zhejiang Province.

Optical metrology tests mainly refer to optical metrology test problems that cannot be solved using conventional optical metrology standards and measurement devices. For example, the high-energy laser energy in the order of several tens of thousands joules, the pulse width in the femtosecond-order pulse characteristics, the scale and the surface smoothness in nanometer materials and devices, and the large-scale astronomical telescope with a diameter of several meters are involved in the measurement test problem.

Optical metrology is one of the ten major disciplines in metrology, and it is based on optical physical measurement technology and quantitative transmission. Its main task is to continuously improve the optical measurement unit system, reproduce physical units, study new measurement standard instruments and standard devices, establish a value transfer system and transfer methods, develop new test technologies, and study new optical metrology theories. With the advancement of science and technology, optical metrology test technology has developed rapidly and has become an important supporting technology in the optical industry.

The project was improved through instrument procurement and existing experimental platforms, and a femtosecond laser-based metrology technology research platform and an ultra-fast optical parameter measurement and test platform were constructed, forming research and measurement testing capabilities in the field of ultrafast optics. At the same time, the platform is open to the society through the sharing of instruments. It provides effective technical support for technical research in the field of optical metrology and ultra-fast laser metrology services for industrial use as well as laser processing and medical diagnostics in our province.

Introduction of Commercial Peanut Roaster Machine: 
The machine is a horizontal drum roasting machine that uses direct fire for materials. It is composed of a horizontal drum boiler body, a pan support frame, a frying pan arch, a power transmission part, and a charging and discharging mechanism. The roller pot body is mounted on the support frame of the pot body through the bearing, and the roller pot body can rotate around the roller shaft. Under the direct fire action, the materials contained in the roller pot body are evenly baked, and the roller pot body is also heated evenly. The wok burst accident occurred. The upper part of the arch body adopts a detachable vault for easy maintenance and repair.
Use of Peanut Drying Equipment
The dryer machine is suitable for all roasted seeds and nuts, raw material processing of health products, processing of nutritious raw materials, processing of raw materials for Chinese herbal medicine shops, condiments and spices processing, dried coffee beans, chestnuts, peanuts, melon seeds, walnuts, sesame seeds, beans, rice, hazelnuts, pine nuts, pistachios and other dried fruit foods.
Advantages of Nuts Dryer Machine:
1. Roasting time can set up according to client need or material. When time is on, machine will warn.
2. Heating effect is uniform. Machine is constantly rotated. Back and forth, up and down, all heating well from different direction.
3. It can large increase roasting material oil squeezing rate. Usually equipped with oil press machine.
4. Roasting time is short. Each time it needs about 20minutes. Of course, different situation, roasting time will be a little different. For example, if you won't need the soybean skin crack, then 20 minutes is ok, if you will need the skin crack completely, then need about 40min one time.
5. Reasonable structure, low energy consumption, high efficiency, safety.
6. Low investment costs. Machine price is low, and have many models from small to large, customers can choose according to their needs.
