Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a multi-circuit continuous tea cooling machine. Background Art

[0002] Tea refers to the leaves of the evergreen shrub tea tree that can be used to make tea. Tea contains catechins, cholestenone, caffeine, inositol, folic acid, pantothenic acid and other ingredients that can improve human health. Tea needs to undergo deep processing during the production process. Deep processing of tea refers to using fresh tea leaves and finished tea leaves as raw materials, or using tea leaves and waste and scraps from tea factories as raw materials, and using corresponding processing technologies and means to produce tea-containing products. After the tea leaves are dried, the temperature of the tea leaves is very high and the tea leaves need to be cooled quickly to prevent the high temperature and heat from causing the tea leaves to deteriorate. However, a tea cooler is needed when cooling the tea leaves. As a process in tea production, it is an important processing step in the tea production process.

[0003] Traditional tea cooling methods include natural cooling (spreading to cool) and forced air cooling by fans during transportation. In the case of natural cooling, the tea takes a long time to cool down, the cooling area is uneven, and it needs to be turned over manually at regular intervals, which is labor-intensive. In the case of forced air cooling by fans, it is mostly carried out on the conveyor chain plate. Due to the limited conveying distance, the contact time between the tea and the cold air is short, resulting in incomplete and incomplete cooling. Utility Model Content

[0031] See also Figure 2 , Figure 3 and Figure 4 A cooling plate 5 is installed inside the first cooling device 2, and an air duct 6 is installed at the bottom end of the cooling plate 5.

The collection box 9 is slidably connected to the air duct 6 through the installation groove 8. The collection box 9 is a hollow structure, and a layer of filter is installed inside it.

[0034] Working principle: First, the tea leaves that need to be cooled are transported to the first cooling device 2 through the transportation device, and the fan 7 is started to blow air into the air duct 6 through the fan 7, so that the wind is blown out through the cooling plate 5 and the tea leaves on the cooling plate 5 are cooled. At the same time, the eccentric motor 14 drives the driving rod 13 to operate, which can push the air duct 6 to vibrate back and forth, so that the tea leaves slide along the cooling plate 5 on the first cooling device 2 and fall onto the second cooling device 3 through the guide groove 15 installed at the end of the cooling plate 5.

The collection box 9 can be removed by sliding it, and the impurities collected inside can be cleaned, thereby preventing impurities from accumulating in the air duct 6.
