Many types of insulating materials, can be divided into gas, liquid, solid three categories. Commonly used gas insulation materials are air, nitrogen, sulfur hexafluoride insulation PC film. Liquid insulating materials are mainly mineral insulating oil, synthetic insulating oil (silicone oil, dodecyl benzene, polyisobutylene, isopropyl biphenyl, diaryl ethane, etc.) two categories. Solid insulation materials can be divided into organic and inorganic two categories. Organic solid insulating materials, including insulating paint, insulating plastic, insulating paper, insulating fiber products, plastics, rubber, varnished paint and insulation impregnated fiber products, electrical film, composite products and tape, electrical laminates. Inorganic solid insulating materials are mica, glass, ceramics and their products. In contrast, a variety of solid insulating materials, but also the most important. Different electrical equipment on the performance requirements of insulating materials have different emphases. High voltage electrical equipment such as high voltage motors, high voltage cables and other insulation materials require high breakdown strength and low dielectric loss. Low-voltage electrical appliances are based on mechanical strength, elongation at break, heat-resistant grade as the main requirements. Macroscopic properties of insulating materials such as electrical properties, thermal properties, mechanical properties, chemical resistance, weather resistance, corrosion resistance and other properties and its chemical composition, molecular structure and so on are closely related. Inorganic solid insulating material is mainly composed of silicon, boron and a variety of metal oxides, the ionic structure-based, the main features of high heat resistance, the working temperature is generally greater than 180 ℃, good stability, resistance to atmospheric aging resistance Chemical properties and long-term aging in the electric field under the good performance; but high brittleness, low impact strength, high pressure and low tensile strength; poor technology. Organic materials are generally polymers with an average molecular weight of between 104 and 106, which are generally less heat resistant than inorganic materials. Containing aromatic rings, heterocyclic and silicon, titanium, fluorine and other elements of the material's heat resistance is higher than the average linear polymer chain. Important factors that affect the dielectric properties of insulating materials are the molecular polarity and the content of polar components. Polar materials, dielectric constant, dielectric loss are higher than non-polar materials, and easy to adsorb impurity ions to increase conductivity and reduce the dielectric properties. Therefore, in the insulating material manufacturing process should pay attention to clean, prevent pollution. The capacitor dielectric requires a high dielectric constant to improve its specific characteristics. Introduction of Commercial Peanut Roaster Machine: Peanut Dryer,Peanut Dryer Tower,Peanut Dryer Machine,Tower Dryer For Peanut JINFENG DRYING EQUIPMENT CO.,LTD , https://www.jf-graindry.com
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.
