In the season when Apple is ripe, not all apples can be harvested. Due to different maturity levels, harvesting time is not the same. If apple harvest should not be too early, it should not be too late because it is premature. Poor quality, low yield, and prone to physiological disease; too late, some varieties of fruit will become cotton, perishable, flavor will be reduced. Therefore, it is critical to determine the appropriate harvest time for apples, and the determination of harvest time is based on judging the maturity of apples. Therefore, using the fruit hardness tester to determine the hardness of fruit trees, it is possible to determine the maturity of apples and harvest the crops in proper time. The timing of the determination provided the basis. Aroma Waterless diffuser Fragrance lamp

In general, the hardness of apples, pears, strawberries, grapes and other fruits reflects the maturity of the fruit to a certain extent. This is mainly because when the apple begins to mature, a series of biochemical changes will occur within the fruit. Under the action of pectinase, insoluble protopectin will be hydrolyzed into soluble pectin and cellulose, making the flesh cells loosely connected and the fruit become both soft and brittle. Therefore, the use of fruit hardness tester to determine the hardness of the fruit can determine the maturity of apples, pears, strawberries, grapes and other fruits, then use it to determine the appropriate apple harvest time is also very appropriate. In addition, because the fruit hardness tester has the advantages of small size, light weight, intuitive reading, and easy carrying, it is very suitable for on-site testing. Therefore, it also provides natural convenience for its application in orchards. At present, qualified fruit tree farms have begun to use the fruit hardness tester to determine whether apples and other fruits are mature.
Not only that, the application of fruit hardness tester can also provide scientific basis for the transportation of apples, which can effectively reduce the damage and backlog caused by the lack of fruit hardness in the transport process, and extend the shelf life of the fruit. Therefore, the fruit hardness tester has very important applications in the fields of breeding fine seeds, harvest storage, export transportation and processing.

A good aromatherapy machine can have a very good aromatherapy effect and bring a very good aromatherapy atmosphere to our room. Today, Xiaobian mainly introduces some characteristics and working principle of the aromatherapy machine to help you better buy and use the aromatherapy machine to bring good results.
Principle of aromatherapy machine - Characteristics of aromatherapy machine
1. Purify the air. The essential oil aromatherapy machine produces a large number of active oxygen negative ions, which have a strong reaction with harmful gas molecules in the air and are comprehensively removed to completely eliminate the harm of formaldehyde, benzene and ammonia.
2. Safe to use. The cold fog generated by the essential oil aromatherapy machine can 100% distribute and maintain the active ingredients of the essential oil, making the essential oil easier to be completely absorbed by the human body, so as to exert the maximum effect; You can feel the original fragrance effect in 2 seconds. It is fundamentally different from the traditional heating and combustion hot fog methods. Its cold fog technology does not damage any components of essential oil, does not produce secondary pollution, and is safer to use.
3. Small size. The water volume of the essential oil aromatherapy machine is about 100ml. Only 1-2 drops of essential oil can be added to the water to achieve the aromatherapy effect, which is in line with the use of this precious product of essential oil and is economical and applicable. The humidifier has large volume and capacity, mostly about 1L.
4. Strong corrosion resistance. A good essential oil aromatherapy machine is made of special ABS materials, and the metal sheet is also special, which can resist oil, water and chemical corrosion.
