AI Technical Summary
In the constant temperature drying process of existing tea drying equipment, high temperature easily leads to over-drying, while low temperature leads to slow drying. It is difficult to achieve a balance between rapid evaporation of water when the tea leaves are wet and slow cooling after drying.
The tea drying equipment adopts zoned temperature control, and the tea leaves are sequentially passed through the high temperature zone, medium temperature zone and low temperature zone by the conveyor belt. The movement of the sealing plate and the heat preservation partition is utilized to realize the segmented processing of the tea leaves in different temperature ranges. The filter screen turning and the strip structure are combined to accelerate the drying process.
It achieves rapid evaporation of water from the tea leaves when they are wet, and slow cooling after drying, preventing over-drying and improving drying efficiency and the continuous processing capacity of tea leaves.

Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of tea making, and particularly relates to a tea drying equipment. BACKGROUND
[0002] Tea refers to the leaves and buds of the tea plant. It is also called tea, camellia, and mian. It refers to the leaves of evergreen shrubs that can be used for tea, as well as the beverage made from these leaves. Later, it was extended to all herbal teas made from flowers, leaves, seeds, and roots of plants.
[0003] Currently, for green tea and other tea that does not require fermentation, the tea is dried after rolling, without the fermentation process.
[0004] Currently, the tea is dried at a constant temperature. Since the tea is wet in the early stage and dry in the later stage, the temperature is high during constant temperature drying, which easily causes the tea to be over-dried in the later stage, while a low temperature leads to slow drying of the tea that is wet in the early stage. INVENTION CONTENTS
[0005] The utility model provides a kind of tea drying equipment to solve the defects in prior art.
[0006] The utility model is implemented by the following technical solutions:
[0007] A tea drying equipment includes a conveyor belt device and a drying cylinder with an exhaust port at the top. The conveyor belt of the conveyor belt device passes around the drying cylinder. The two ends of the drying cylinder are sealed by a sealable plate that can move up and down. The drying cylinder is divided into a high-temperature zone, a medium-temperature zone, and a low-temperature zone by a heat-insulating partition. The upper part of the heat-insulating partition can pass through the drying cylinder and move synchronously with the sealable plate. Two slides are provided along the length direction of the drying cylinder. A sliding block that can be detached from the slide is provided on the slide. The sliding block is fixedly connected with a U-shaped frame. A breathable tea storage mechanism is arranged in the U-shaped frame. An upper baffle is fixedly connected to the bottom surface of the U-shaped frame. The conveyor belt is fixedly provided with a lower baffle corresponding to the upper baffle. The lower baffle is located on the trajectory line of the upper baffle. First and second clamping grooves are provided on the heat-insulating partition and are adapted to the slide and the conveyor belt.
[0008] In use, first, the rectangular frame with the sliding block is arranged on the slide. Then, the sealable plate and the heat-insulating partition are opened synchronously, and the conveying device is started. The conveying device drives the conveyor belt to convey. When the conveyor belt conveys, the lower baffle moves, which drives the upper baffle to move. In turn, the green tea to be heated enters the high-temperature zone with the tea storage mechanism. The tea storage mechanism in the high-temperature zone enters the medium-temperature zone. The tea storage mechanism in the medium-temperature zone enters the low-temperature zone. Similarly, the tea in the low-temperature zone comes out. After the tea enters the corresponding position, the corresponding heat-insulating partition and sealable plate are closed. In turn, the tea enters the high-temperature zone, the medium-temperature zone, and the low-temperature zone, respectively. Thus, the tea can evaporate water quickly when it is wet in the early stage, and the water can be reduced slowly when it is dry in the later stage, preventing over-drying.
[0009] As preferred, the tea leaf storage mechanism comprises a ring-shaped filter screen, both sides of the filter screen are sealed by baffles, and a feeding port is formed in the filter screen, an openable mesh cover is arranged on the feeding port, a rotating rod is vertically connected at the center of the baffle, a circular rod penetrating through the U-shaped rod is rotatably connected to the U-shaped rod through a bearing, the opposite ends of the circular rod are detachably fixedly connected to the rotating rod through flanges, a driving motor is fixedly arranged on the U-shaped rod, and the rotating shaft of the driving motor is coaxially fixedly connected to the corresponding side circular rod. The rotation of the rotating shaft of the driving motor drives the rotation of the circular rod, the rotation of the circular rod drives the rotation of the rotating rod, and the rotation of the rotating rod further drives the rotation of the baffle, the rotation of the baffle drives the rotation of the filter screen, and the tea leaves in the filter screen are thus turned over, the drying speed is thus increased, and the dried tea leaves can be poured out through the flanges and the mesh cover.
[0010] As preferred, the upper side of the drying cylinder is provided with a horizontal rod, the bottom surface of the horizontal rod is fixedly connected to the top surface of the heat preservation partition plate and the sealing plate, the top surface of the drying cylinder is vertically connected to one end of an electric telescopic rod, and the other end of the electric telescopic rod is vertically connected to the horizontal rod. The electric telescopic rod is started, the extension and shortening of the movable rod of the electric telescopic rod drives the horizontal rod to move up and down, and the sealing plate and the heat preservation partition plate are thus synchronously moved up and down.
[0011] As preferred, the sliding block is a rectangular block, and a groove is formed in the bottom surface of the sliding block.
[0012] As preferred, a ball cavity is formed in the inner wall of the top surface of the groove, and a ball is arranged in the ball cavity and in contact with the sliding channel. Thus, the friction between the sliding block and the sliding channel is reduced.
[0013] As preferred, a stirring rod is fixedly arranged in the filter screen. The stirring rod can stir the tea leaves when the filter screen rotates, so that the tea leaves are better spread out and the drying speed is increased.
[0014] The application can place tea leaves in the high-temperature zone, the medium-temperature zone and the low-temperature zone in sequence, so that the tea leaves can quickly evaporate water when they are wet in the early stage, the water can be slowly reduced when the water is reduced, the tea leaves can be prevented from being over-dried, the continuous drying of the tea leaves can be ensured, and the drying efficiency is improved.
