No. According to a query from the Chinese Food Network, the effect of blowing moisture out of eggplants with a hair dryer is not ideal. They must be steamed and exposed to the sun. The best way to dry eggplants is to use fresh, round eggplants. flesh. Cut the eggplants into long strips for easy drying. Add an appropriate amount of salt to the eggplant to kill the water and reduce the humidity inside the eggplant. Steam the water-killed eggplant for a few minutes. Steam eggplant and expose it to the sun until it is completely dried. Then put it in a bag to store it.
How to use solar energy to produce electricity?
Solar panels produce direct current and the voltage is relatively low. It is necessary to use an "inverter" to convert DC power to 220V AC power for use.be used by the food supply. The equipment includes solar panels + battery + inverter. For your use, it is estimated that the equipment will cost thousands of dollars.
It is more convenient and saves money to run a wire from another room.
How do insulated shoes work?
Scientists agree that using solar airflow to generate electricity is the most economical and more efficient in producing electricity. In the center of the ceiling of a huge greenhouse covered with transparent plastic panels, there is an air duct. When the air in the greenhouse is heated by the sun to a temperature 60°C to 67°C higher than the outside air temperature, the cold air outside will push against the greenhouse. The hot air inside makes it rise along the long wind blade to form a strong airflow, which pushes the turbine installed on the cylinderwind power to drive the engine and produce electricity.
Summary: Insulated shoes are a kind of safety shoes made from insulating materials. When working in the electrical industry, postal and telecommunications and electricians, insulated footwear should be worn. the current follows a certain path to prevent the electric current from passing through the human body and causing electric shock damage to the human body. When using insulated shoes, be careful not to get wet and should not wear them on rainy days. Take good care of the leather surface and other elements. After 6 months of wearing insulated shoes, a preventive test should be carried out to test their durability and wear. For daily maintenance of insulated shoes, you should apply shoe polish frequently and avoid exposure to sun and fire. Let’s discover insulated shoes together. LThe working principle of insulating shoes
The so-called insulation refers to the use of insulating materials to seal charged objects, thereby insulating charged objects or conductors with different potentials, so that current can flow in a certain path. . Good insulation is a necessary condition to ensure the normal operation of equipment and lines, and is also an important measure to prevent electric shock accidents. Insulating materials often play other roles: heat dissipation and cooling, mechanical support and fixation, energy storage, arc suppression, protection from moisture, mold, and conductors.

Insulated shoes are a type of safety footwear made from insulating materials. Since current flows through the ground through the human body via the contact point during an electric shock, you must wear insulating gloves as well as insulating shoes when carrying out electrical work.
Precautions for using insulated shoes
1. Insulated shoes are suitable as auxiliary safety equipment and labor protection equipment when working on electrical equipment with AC 50 Hz and less than 1000 V or DC less than 1500 V. to carry. Workers use insulated leather shoes, which can be used with basic tools to touch live parts and can be used to protect against blows caused by stepping tensions. Step voltage refers to the potential difference between two points located at0.8 m in the direction of the maximum potential gradient of the ground when the electrical equipment is earthed.
2. Be careful not to let this product get wet. It is strictly prohibited to use it once wet, place it in a ventilated and cool place to dry naturally to avoid deformation. and damage to leather shoes. Once the sole has been pierced by a foreign object, it cannot be used as an insulating leather shoe.
3. Pay attention to the maintenance of the leather surface of leather shoes and polish them frequently. The wiping method is as follows: first wipe the dust on the surface of the leather shoes with a clean soft cloth, then squeeze the shoe polish onto the cloth and apply it evenly to the shoe surface, wait for a moment (the shoe polish is slightly dry) then wipe.
4. Insulated shoes should not be worn on rainy days.or washed, otherwise they are subject to disconnection, degumming, discoloration, salt gel, etc.
5. Insulated shoes cannot contact oil, acid, alkaline and sharp substances to avoid corrosion, deformation and damage.
6. It is normal for leather shoes to have slight wrinkles and deformation after wearing them.
7. When insulated shoes get wet or suffer from sweaty feet, they are prone to salt gel. In case of salt frost, you can use gauze or cotton dipped in a small amount of warm water to wipe the white salt frost on the shoes. Place the shoes in a ventilated area to dry, then wipe them with shoe polish. Repeat several times. times to return them to their original state. So keep your leather shoes dry.
8. When storing insulated shoes,leather shoes should be kept clean, dry, well polished and laid flat naturally: after a period of storage (especially in the rainy season), leather shoes should be ventilated, cooled and dried frequently, and wiped dry. new to avoid mold.
Insulation footwear inspection cycle and test methods
1. After 6 months of wearing the product, preventive testing should be carried out for unqualified products due to puncture by sharp objects. , They should no longer be used as insulating shoes.
2. Preventive testing, for 6KV leather insulated shoes, 5KV voltage testing should be used. 5KV fabric covered rubber shoes are tested with 3.5KV.
3. Degree of corrosion. According to different operations, the wear of insulated labor protection shoes can be divided into heavy corrosion, medium corrosion and light corrosion. the usage of the user.
4. Electrically insulated and durable labor protection shoes include four categories: electrically insulated leather shoes, plastic shoes, rubber-covered rubber shoes, and fabric-covered rubber shoes. According to its lifespan, it is divided into non-durable, moderately durable and durable. Durability can reflect the material quality of insulated labor protection shoes.
5. The loss, according to the degree of reduction of the protective function of insulated labor protection shoes, can be divided into vulnerable loss, medium damage and fall. shoes.
How to maintain insulated shoes
1. Shine shoes frequently. When applying shoe polish, clean it first. Use a soft, clean cloth to wipe off the dust on the surface of the leather shoes. Avoid washing them with water and tout contact with chemical solvents. Then apply the oil evenly and wipe it off. After applying the oil, wait about 5 minutes, then use a brush or floss to lighten the top part.
2. Often keep it dry and avoid wearing it in rain or snow. If you encounter rain, snow or water, dry them immediately with a dry cloth and apply shoe polish. Leather shoes should not be exposed to the sun or burned by fire. Exposure and cooking will quickly evaporate the oil inside the leather, making the leather hard, making the leather fibers brittle and easy to break. If there is a lot of sweat and moisture in the shoes, they can be dried in a place away from the sun. Or place it in a dry place to dry in the shade. You can also dry it next to the air conditioner or with a hair dryer.
3. Insulated shoes have strong capacityto absorb sweat. Sweat in shoes will cause moisture in the shoes. This environment can easily breed bacteria. Timely replacement of shoes can allow moisture and sweat to completely dissipate, thereby protecting the physiological functions of leather shoes and feet. It is best to wear a pair of insulated shoes every other day.
4. The uppers of insulated shoes are very greasy, but you should not soak them in oil, especially the uppers.
5. Dirt, mud and dust should be removed promptly and carefully from insulated shoes that are not in temporary use. Then carefully apply the shoe polish. Do not apply too much shoe polish when storing. Applying too much shoe polish will cause the leather surface to become brittle if stored for a long time. When storing, it is best to apply a little chicken fatand raw, raw lard or glycerin to keep the leather surface soft and moist without deformation.
