Using Plant Respirometers to Study Postharvest Respiration of Fruits and Vegetables

Before harvesting, fruits and vegetables can be supplied with nutrients from the roots to keep them fresh, but after harvesting, if they are still fresh, they can only be achieved through technical means. The post-harvest respiration characteristics of fruits and vegetables are important for studying their preservation techniques, such as harvest time, storage temperature, and preservation measures taken. It will help to explore feasible solutions for fruit and vegetable preservation and improve the storage and transportation effects of fruits and vegetables after harvesting.

Plant Respiratory Tester


After harvesting fruits and vegetables, although the communication function basically stopped, the respiration has become the dominant aspect of metabolism, and the respiration will directly and indirectly connect with various physiological and biochemical processes, thus affecting the storage and disease resistance of fruits and vegetables. The development of change. The relationship between the post-harvest respiration characteristics of fruits and vegetables and the storage characteristics of fruits and vegetables is that the more vigorous the respiration is, the faster the various processes change, and the more intolerant the storage of fruits and vegetables is, so during the storage and transportation of fruits and vegetables, it is necessary to use plant respiration. The instrument measures the post-harvest breathing characteristics of fruits and vegetables, and effectively controls the respiration and metabolic intensity of fruits and vegetables to prolong the storage cycle of fruits and vegetables and improve the quality of fruits and vegetables.
The main content of the plant respiration tester is an important indicator of the post-harvest respiration characteristics of fruits and vegetables - respiratory intensity. The instrument measures the post-harvest respiration characteristics of fruits and vegetables by measuring the CO2 concentration, O2 concentration, temperature and humidity of the respiratory chamber. It provides two indication methods for the respiratory characteristics of fruits and vegetables, namely CO2 concentration and O2 concentration, so it is more functional than the CO2 analyzer used in the past. It is versatile, high-precision, fast, efficient and convenient. . At present, the use of plant respiration apparatus to study the post-harvest respiration characteristics of fruits and vegetables is the most effective and reliable method for quickly and accurately measuring the post-harvest respiration intensity of fruits and vegetables in food, gardening, fruit, vegetables, foreign trade and other types of schools and research. The institutes and companies have very important applications in the respiration measurement of various fruits and vegetables.

Heating Element For Water Faucet


Water faucet is more and more high-tech. Not only instant electric hot water faucet brings great convenience to people, but also a lot of problems. The quality of instant electric hot water faucet mainly depends on the material of heating body. Jieda Andetong stainless steel thick film heating pipe is a new type of instant heating technology which is popular in Europe and the United States. It uses screen printing technology. After seven times of high temperature sintering of insulation resistance, it is perfectly attached to the outer wall of stainless steel pipe and has a long service life. There are two main types of thick-film heaters, stainless steel thick-film Heating Plate and stainless steel thick-film heating pipe.

The first brand Feiyu in China of electric water faucet is our major customer.
