What are the techniques for making crude tea from jasmine?
The purpose of the operation is to fish out the long tea and long stems that do not meet the specifications, and divide the preliminarily shaped tea leaves into three categories, namely, long tea that does not meet the specifications, strip tea that basically meets the specifications, and short tea. Therefore, clear segmentation is required. Tea serving cannot contain strips of tea with a length exceeding17 mm. This operation can also reduce the workload of the flat circular knitting machine.

The fishing screen adopts a rotary plane circular screen machine with a rotating speed of 200 ~ 220 rpm and an inclination angle of 3 ~ 4, all of which are equipped with aluminum round-hole screens.

The tea on the first side of the sieve is called fish head, which is a long tea stalk and is treated in a round way. The tea screened on the second side is called noodles, which are tea strips with specifications. The tea screened on the second side is called the lower segment, which is the raw material of the middle and lower segments of tea.

The primary fishing screen is primary fishing, with two round holes and three points of tea. The first one is called Yutao, the second one is called Yuyu, and the third one is called Xiaduan, which is the raw material of the middle and lower sections. Due to the smaller strip shape, the first screen hole of the second and above levels is 1 mm tighter than that of the third level, and the flow rate of the second screen is smaller. In order to meet the screened tea leaves, it is divided into the upper half and the lower half, with different configurations. Before serving tea, press the grading sieve; Wash the screen regularly; When entering the tea, it should be continuous and uniform, covered with sieve surface, and based on the principle of no broken surface and no accumulation.
