The low level of automatization of domestically produced drying equipment and the backwardness of control means are common problems. As far as the current level of automation is concerned, it is not difficult to solve the control problem in the drying equipment, but what is lacking most is the problem of the reasonable combination of the automatic control technology and the drying equipment. As mentioned earlier, different materials have different requirements for dryers. Similarly, there are major differences in the requirements for control methods for different materials. The role of automatic control in the dryer is well-known, but its one-time investment is also the issue that people are most concerned about. Sometimes the investment in control equipment even exceeds the investment in the mechanical part of the dryer. It is also the subject that research should be carried out to determine a reasonable control plan for dryers and drying process requirements and to determine appropriate control measures for specific drying projects. In addition, it should also pay attention to the magnification of drying equipment . The enlargement involves disciplines such as fluid mechanics, mechanics, thermodynamics, heat transfer, materials science, dust removal, corrosion protection, electrical appliances, and control. It is very likely that some problems will arise during the amplification process. Therefore, the amplification of the drying device is by no means a simple geometrical enlargement. In this respect, it largely depends on the experience of industrialization, the mastery of the physical properties of materials and the understanding of drying equipment. The phenomena that may occur during the enlargement process should be predicted rationally and objectively, and corresponding solutions can be proposed. The so-called research amplification effect is to grasp the drying theory and drying technology while paying attention to accumulating practical experience and summing up lessons. What if the air is dry
(2) Reduce the frequency of washing your face with hot water, 1 ~ 2 times a day, and wash your face with less alkaline soap.

Dryness in spring and autumn is unavoidable Dry skin, it is best to drink plenty of water, maintain the body's water supply, according to their skin characteristics properly wipe the moisturizing cream or mask. Green plants and air humidifiers can be placed indoors
In winter, with the decrease of temperature, the skin will become tight and dry due to the reduction of sweat gland and skin gland secretion and the loss of more water. Therefore, it is more important to carry out beauty and skin care in winter.
(1) skin oil cream should be applied to the exposed skin before going out, especially lip balm.
(3) massage the facial skin regularly to promote blood circulation and use 1~2 times a week.
(4) After washing your face, apply oil and skin care cosmetics. If there is a crack in the skin of hands and feet, you can apply some anti crack ointment.
(5) Drink more water, eat more fresh fruits and vegetables, and eat an appropriate amount of chicken, fish and meat to supplement water and nutrition in the body.
Winter skin cleaning tips
In the middle of winter, girls are facing great enemies and start "skin care mobilization" one after another. But the first step of skin care - cleaning is often ignored, at least not as much as in summer. In fact, in winter, the north is windy and dusty, and the air is dirty. Everyone uses oily skin cream one after another; The air in the south is cold and humid, and it is difficult for the skin to breathe freely. Therefore, we should pay more attention to skin cleaning in winter.
Proper skin cleaning methods can gently and effectively wash pores, help skin absorb the essence of skin care products, and achieve twice the result with half the effort.
Winter cleansing care tips:
In winter, it can clean the face and take comprehensive care at the same time, promote the metabolism of the skin slowed down due to the severe cold, and reduce the appearance of fine lines on the surface.
Wash your face before bathing in winter. Because the water temperature is often high when bathing in winter, cleansing with water at this temperature will lead to the aging of facial skin; At the same time, the hot steam in the bathroom opens the pores. If it is not cleaned in advance, it will be more difficult to clean the dust and dirt on the surface of facial skin into the pores.
The air in the north is dry in winter, so wash your face as much as possible in winter. Generally, you can wash your face once in the morning and once in the evening. Don't wash your face with overheated water, because too hot water will over decompose the skin's oil, make the skin dry and easy to wrinkle; And too cold water is difficult to clean the dirt and excess oil in the pores, so warm water cleansing is the right choice. After cleaning, tap cold water on the cotton cloth to shrink the pores. Pay special attention to moisturizing after cleansing to provide gentle and moisturizing care for the skin.
