1. Easy to transport. The nut sorting machines is easy to carry, light and convenient, and can be cleaned more conveniently after use, meeting the needs of many manufacturers.
2. Sorted. The color sorter adopts modern CCD technology and computer-aided control technology. Through the analysis of the optical properties of the product, it can quickly distinguish the good from the bad, and achieve the effect of optimizing the product.
3. Easy to operate. The color sorter is intelligently controlled by computer, one operation, control system, parameter writing into the touch screen, etc. The operation is also very simple, and ordinary workers can master it proficiently after a short period of training.
4. Compared with manual selection, it saves labor, time and reduces labor costs.

From the perspective of drying performance
Freeze dryer has lower energy consumption and operating cost than adsorption dryer, but it cannot provide deep dry compressed air like adsorption dryer. The pressure dew point of freeze dryer is usually above 3"Ctd. For general As far as the manufacturing process is concerned, it is sufficient to choose a air dryer refrigerant ; for some higher requirements and drier compressed air, an adsorption dryer should be selected.
From the perspective of the installation environment
The refrigerated dryer has weak adaptability to the environment. Too high or too low ambient temperature is not conducive to the operation of the equipment: too high ambient temperature will lead to an increase in the condensation pressure of the refrigerant in the air-cooled refrigerated dryer, which will reduce the cooling capacity and increase The pressure dew point at the outlet of the equipment; if the ambient temperature is too low, especially below 0°C, ice blockage will easily occur when the condensed water of the cold dryer is discharged outside. Adsorption dryers have relatively strong adaptability to ambient temperature, but the influencing factors of high compressed air pressure dew point value caused by high air compressor outlet temperature at the highest ambient temperature must be taken into account when selecting equipment.

The specific use time of a kn95 disposable face mask needs to be determined according to the situation after wearing it. Generally, it can be used for 4 to 6 hours, and no more than eight hours at most.
Do not use the mask for too long, and do not use it repeatedly, otherwise the respiratory impedance will drop significantly. At present, for the prevention of new coronavirus, KN95 masks are recommended to be used for no more than eight hours, and can generally be used for 4 to 6 hours. Once the mask is contaminated by the patient's blood, respiratory secretions, and other body fluids, it needs to be replaced in time.
The use of KN95 masks must be determined according to the personal situation and environment. Once discomfort such as difficulty in breathing occurs, it is necessary to go to a place with fewer people and fresh air in time. If there is obvious discomfort, please seek medical treatment in time to avoid delay in treatment.

1. Selection of light sources and lamps
choose the right light source
Scientific and reasonable selection of light sources and lamps is of great significance to lighting engineering.best light city . In the actual selection process, the light distribution curve and the lamp with high efficiency should be the main ones. Different light sources have different characteristics, and comprehensive consideration should be given to each use environment and requirements to ensure the scientific rationality of the selected light source.
Choose the right light fixture
The lamps and lanterns must have the function of adjusting the horizontal and vertical directions. At the same time, they must have a firm locking device, have good corrosion resistance, and have high waterproof and dustproof functions.
2. Urban lighting design
Landscape lighting architecture: The design of landscape lighting architecture needs to refer to a variety of basic data and document regulations at the same time, so as to ensure the scientific and comprehensive planning strategy of landscape lighting architecture. The design of landscape lighting architecture needs to include the point-line-surface relationship of urban lighting, the design of lighting systems, and the order of importance of each link in the urban lighting system.

LED and other installations in the room are not only beautiful but also very practical, so now families will buy LED lamps to decorate the house, and some businesses will wholesale LED lamps. How to choose a wholesale lighting supplier
1. Lamp manufacturers with quality assurance
Because LED lamps are mainly installed on the ceiling, if the quality of lamps and lanterns is not good and often damages the family, it needs to be replaced frequently. Frequent replacement will increase the cost of decoration and also affect the sales of other products of merchants. After all, consumers are not good at buying from merchants. products will not be purchased again.
2. Multi-style lighting manufacturers
Some manufacturers have limited economic budgets, so they will focus on the quality of research and development products and reduce the design of various styles. Although the quality of this kind of lamps is also very good, it may be that no one cares because the styles do not meet the public's aesthetics. Businesses purchase LED lamps to make money. If LED lamps cannot be sold wholesale, even the best lamps will not make money.
In general, the purpose of wholesale LED lamps is to make money. Choosing a manufacturer with quality assurance can help you sell lamps and open the market for other products. Considering the aesthetic needs of customers, you should choose manufacturers with multiple styles.
