Description

An electric heating Biluochun dryer

technical field

The utility model relates to the field of tea preparation equipment, in particular to an electric heating type Biluochun dryer.

Background technique

There are three methods of drying tea leaves: drying, frying and sun-drying. 1. The drying process of green tea is generally dried first, and then fried. Because the water content of the rolled tea leaves is still high, if they are fried directly, they will quickly form lumps in the pot of the frying machine, and the tea juice will easily stick to the pot wall. Therefore, the tea leaves are first dried to reduce the water content to meet the requirements of pan frying. 2. The drying of black tea is the process of roasting the fermented tea base at high temperature to quickly evaporate the water to achieve the dryness of the quality. 3. White tea is a special product of our country, mainly produced in Fujian Province. White tea is made by drying in the sun without frying or kneading. 4. Black tea can be dried by roasting or drying in the sun to fix the quality and prevent deterioration.

Biluochun is a kind of green tea. In order to produce Biluochun tea leaves with relatively good texture, it is necessary to control the moisture content of the tea leaves before frying. Therefore, a Biluochun drying method that can effectively control the moisture content in the tea leaves and has a relatively simple operation process has been developed. machine is very necessary.

Utility model content

The purpose of the utility model is to provide a Biluochun drying machine which can effectively dry Biluochun tea leaves and is easy to operate.

The specific technical solution of the utility model is: an electric heating type Biluochun dryer, including a box body, a blower, an electric heating unit and a drying bin are arranged in the box body, and a A hopper connected to the drying bin, the drying bin is a horizontal cylindrical drying bin, the curved surface of the drying bin is provided with an air inlet tangent to the curved surface of the drying bin, the The electric heating unit is arranged between the air inlet and the air outlet of the blower, and a plurality of air outlets are arranged on the curved surface of the drying bin, and the diameter of the air outlets is smaller than the particle size of the material to be dried , both ends of the drying bin are provided with feed ports, the feed ports are connected to the hopper, the hopper is provided with a feed valve, and one end of the drying bin is provided for discharging The material discharge port is connected with a discharge pipe extending to the outside of the box, and the other end of the drying bin is provided with an auxiliary blower.

In the above-mentioned electric heating type Biluochun dryer, the electric heating unit includes a heating pipe, and the first spiral electric heating wire and the second spiral electric heating wire are arranged in the described heating pipe, and the first spiral electric heating wire The shaped heating wire is arranged inside the second helical heating wire and the first helical heating wire and the second helical heating wire are coaxially arranged.

Compared with the prior art, the utility model has the beneficial effects of:

1. This scheme adopts a horizontal cylindrical drying bin, which can effectively dry the tea leaves and maintain the integrity of the tea leaves well.

2. This scheme adopts the setting of double helical heating wires, which can provide better heating effect than the helical heating wires arranged side by side during heating, and has the advantages of fast heating and stable heating.

3. This scheme adopts the operation method of feeding materials at both ends of the drying chamber and blowing materials at one end. On the one hand, it is not necessary to consider whether the feeding is uniform, because the centrifugal force of the air and the setting of the exhaust port are conducive to the material at the feeding port. It is imported into the drying bin, and after drying, it can be discharged smoothly through the auxiliary blower.
