Description

Pneumatic drying sieving mechanism of tealeaves

Technical Field

The utility model belongs to the technical field of tea making equipment, concretely relates to air drying sieving mechanism of tealeaves.

Background

The screening of tealeaves is the key step in the tea-making process, the sand and stone in the tealeaves, dust and other impurity are filtered out to the screen cloth that generally adopts the sieve separator, for making the tiny dust that attaches to tealeaves surface obtain abundant screening, set up multistage screen cloth often or adopt the mode of violent shake, lead to the fresh leaf in the tealeaves material to suffer destruction, and make the tealeaves form through the reason strip design warp, the off-the-shelf quality of tealeaves has been reduced, multistage screen cloth or the structure of violent shake must increase the cost of equipment manufacturing and energy resource consumption simultaneously, and still be difficult to thoroughly clear away to the intractable dust that attaches to tealeaves, be unfavorable for drinking tea user's health.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides an air flow drying and screening device for tea leaves, which is used for thoroughly removing the intractable attached dust on the surface of the tea leaves to obtain a high-quality tea product.

The technical scheme of the utility model as follows: an airflow drying and screening device for tea leaves comprises a screening tank, a screen, an air cylinder, an airflow dryer and a guide pipe. The screening tank is placed on the working platform or the ground, the top surface of the screening tank is provided with a feeding port, the bottom surface of the screening tank is provided with a liquid discharging port, and the side surface of the screening tank is provided with a material taking port; the screen cloth sets up in screening jar inner chamber, and the cylinder is installed in screening jar top surface to stretch into screening jar inner chamber with its output shaft and be connected with the screen cloth, make it can drive the screen cloth and make the motion of vertical direction. The pneumatic dryer is arranged on one side of the screening tank and is connected with the screening tank through a guide pipe. Before the screening work is carried out, low-temperature cold water is firstly added into an inner cavity of the screening tank through the feed inlet, the air cylinder drives the screen to be positioned above the liquid level of the cold water, then tea materials are poured into the screening tank through the feed inlet to fall above the screen, the air cylinder is started to enable the screen to make reciprocating motion along the vertical direction, the screen and tea carried by the screen are quickly immersed into the cold water to be flushed, then the cold water floats out of the liquid level, and the process is repeated. After a period of time, opening a liquid outlet to discharge cold water containing impurities, closing a feed inlet, starting an airflow dryer, inputting high-speed hot airflow into the screening tank through a guide pipe, performing airflow drying operation on wet tea leaves on the screen, and opening a material taking port to take out the screened tea leaves after the period of time.

The utility model has the advantages that:

1. the utility model discloses a with the short time, the cold water of many times erodees, clear away dust and impurity in the tealeaves, owing to controlled washout time and temperature, make the solubility of the original composition of tealeaves lower, utilize air current drying to make moist tealeaves rapidly dry simultaneously, kept the original quality of tealeaves as far as possible when implementing filtering operation, compared in prior art's sieve net structure, the utility model discloses there is not mechanical property's destruction to the screening of tealeaves to can implement to erode the filtration to the intractable tiny dust on tealeaves surface, obtain the tealeaves product that the quality is higher, impurity still less.

2. Through the utility model discloses a scheme, tealeaves fully soak among cold water, erode fast and implement the air current drying rapidly afterwards, obtain the filtration at all-round no dead angle, compare the screen cloth filtration among the prior art, have higher production efficiency.

Detailed Description

The invention is further described with reference to the drawings and examples.

As shown in figure 1, the pneumatic drying and screening device for tea leaves comprises a screening tank 1, a screen 2, a cylinder 3, a pneumatic dryer 4 and a conduit 5. The screening tank 1 is of a hollow container structure and is fixed on the working platform, the top surface of the screening tank is provided with a feeding port 1a, the bottom surface of the screening tank is provided with a liquid discharging port 1b, and the side wall of the screening tank is provided with a material taking port 1 c; the screen 2 is provided with a porous array for filtering liquid and is arranged inside the screening tank 1; the cylinder body of the cylinder 3 is fixed at the top of the screening tank 1, and an output shaft of the cylinder extends into the inner cavity of the screening tank 1 and is connected with the center of the screen 2; the pneumatic dryer 4 is arranged on one side of the screening tank 1 and is connected with the inner cavity of the screening tank 1 through a conduit 5.

The working steps of the utility model are as follows:

the method comprises the following steps: closing the liquid discharge port 1b and the material taking port 1c, opening the material feeding port 1a, adding pure water at the temperature of 0-5 ℃ to enable the pure water to fall into the bottom of the screening tank 1 through the porous array of the screen, and then driving the air cylinder 3 to enable the screen 2 to move to the position above the liquid level of the cold water and keep a certain gap; then the tea material to be filtered is added through the feed inlet 1a and falls on the screen 2.

Step two: as shown in fig. 2, the cylinder 3 is started to rapidly move the screen 2 along the lower part, when the tea material is completely soaked in the pure water for 3-5 seconds, the cylinder 3 is started again to rapidly move the screen 2 upwards, and the operations of descending and upwards moving the screen 2 are repeatedly carried out, and the proper repetition times are set according to the quantity of the tea material, so that the granular impurities and the attached dust on the surface of the tea are fully washed and mixed into the cold water. After the set number of times is reached, the cylinder is stopped, and the liquid discharge port 1b is opened to discharge the cold water containing impurities.

Step three: closing the liquid discharge port 1b, starting the airflow dryer 4 to input high-speed hot airflow into the screening tank 1 through the guide pipe 5, so that the moistened tea material is fully contacted with the high-speed hot airflow, and because the drying time of the airflow drying method is short, the original quality of the tea is reserved, and the drying operation is finished; then, the material taking port 1c is opened to obtain the screened tea material.
