Dryer utilized to tea leaves
If you want to store tea for a long time, you can use drying to maintain its original taste. If you don't dry it, it will easily deteriorate, mold and rot. After a series of processes such as drying and processing, it can be maintained for a long time.
Tea dryers can be divided into hot air drying, metal conduction drying and radiation drying according to the drying method. Different drying methods form different quality tea leaves due to differences in heat transfer, heat exposure, leaf temperature changes, and evaporation rates.
Hot air drying is the most common drying method. Its main process is based on air heat conduction, with fast heat transfer and stable leaf temperature rise. During the drying process, hot air is the main medium, so that the material to be dried can be in contact with it at a suitable temperature, humidity and flow rate, so as to achieve the purpose of uniform drying. Among them, the automatic chain plate dryer is the most representative.
Other new tea dryers. In recent years, some new structure tea dryers have appeared, such as cylindrical structure, which improves the traditional tea dryer in terms of box structure. The circular cylinder is used instead of the rectangular box, so that the hot air circulates in the cylinder, the distribution is even, and the tea baking effect is good. At the same time, the dryer with this structure has a compact structure and a small footprint, and is suitable for drying tea in tea factories.
In this era of tea dryer, it is recommended that you use a heat pump dryer. The heat pump mentioned here is essentially a heat raising device. The high-temperature heat pump dryer uses the reverse Carnot principle to absorb heat from the surrounding environment and convert it Passed to the object to be heated (object with higher temperature), its working principle is opposite to that of the refrigerator, and both work according to the reverse Carnot cycle principle, the difference between the two is that the former increases the temperature and the latter decreases the temperature.
The heat pump drying first has the effect of environmental protection, and secondly, the energy-saving energy efficiency ratio can reach 1 to 3, which means that the output of one degree of electricity can produce three degrees of electricity. There are different subsidy policies in different places, which are currently strongly supported. The tea drying part is like Dongbei’s dryer, which is very professional in drying tea, and it is very good in all aspects.
Dryers are widely used in tea. Different drying methods have different advantages and disadvantages. How to choose a suitable drying method depends on your own situation and combined with the above drying methods to choose a suitable tea dryer. .
The structure of this product is simple, the cost is low, and the practicability is strong. By installing a drying cylinder with a rotating shaft, the drying cylinder can be rotated during drying, which effectively avoids the phenomenon of uneven heating of tea leaves and is conducive to improving drying efficiency. , and the sealed design of the drying cylinder is beneficial to prevent tea dust from harming the health of operators and affecting the service life of mechanical equipment; through the installation of heaters and heating nets, the tea can be dried to make the tea evenly heated; Equipped with a temperature sensor, it can sense the temperature in the drying cylinder, and control the temperature in the drying cylinder through the controller to prevent the temperature from damaging the tea, simple and convenient, easy to use
