Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a modular tea drying unit. Background Technology

[0002] China is the birthplace of tea and the cradle of tea culture. After thousands of years of development, based on processing techniques and tea varieties, a tea system has formed, represented by the six major tea categories of China. Tea processing, also known as "tea making," involves processing fresh tea leaves through various steps to create various semi-finished or finished tea products. Among these, pan-frying is one of the key steps in tea processing, primarily using high-temperature frying to remove moisture, shape the tea leaves, and develop their aroma. While the pan-frying processes vary slightly among different tea types, the core principles are similar. Through precise control of the pan-frying process, the color, aroma, taste, and shape of the tea leaves are ultimately determined, which is a concentrated embodiment of the traditional tea-making experience of "making tea by observing the tea leaves."

[0003] Currently, industrial-scale roasting and drying generally employs semi-mechanized equipment controlled manually. Feeding and unloading are entirely manual operations. To increase production capacity, a company often has a considerable number of roasting and drying machines, requiring a significant workforce. This results in high labor intensity and low efficiency, which does not meet the company's production needs. Furthermore, existing roasting and drying equipment often uses side-heating, which cannot provide uniform and precise temperature control, failing to guarantee tea quality, and the equipment occupies a large area. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing devices and provide a modular tea drying unit. This unit adopts a modular design and can automatically feed and unload multiple drying machines, enabling continuous and uninterrupted tea drying without stopping the machines. This meets the requirements of continuous and automated tea processing, improves processing efficiency, greatly reduces manual labor and labor intensity, and satisfies the production needs of enterprises.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A modular tea drying unit includes a feeding elevator, a feeding conveyor, a number of drying machines arranged side by side, and a pellet burner corresponding to each drying machine. The feeding elevator includes a lifting drive assembly and a lifting conveyor belt. The lifting drive assembly drives the lifting conveyor belt, and the tea leaves are lifted and conveyed upwards by the lifting conveyor belt to the discharge port.

[0007] The feeding conveyor includes a feeding conveyor frame and a horizontal conveyor and a traveling conveyor on it. The horizontal conveyor includes a horizontal conveyor belt and its drive assembly. The discharge port of the feeding elevator is located above the horizontal conveyor belt. Tea leaves falling from the feeding elevator land on the horizontal conveyor belt. The drive assembly works to drive the horizontal conveyor belt to transport the tea leaves to the left or right, until they fall at the horizontal discharge port at the end. A track is installed on the feeding conveyor frame below the horizontal conveyor, and a trolley conveyor is located on the track. The feeding conveyor frame below the trolley conveyor is equipped with a feed hopper for the roasting dryer corresponding to it. The trolley conveyor can move back and forth on the track and includes a motion drive component, a trolley conveyor belt, and a trolley conveyor belt drive component. Tea leaves falling from the horizontal conveyor land on the trolley conveyor belt. The motion drive component controls the trolley conveyor to move to the position of the roasting dryer where tea leaves need to be fed. The trolley conveyor belt drive component drives the trolley conveyor belt to transport the tea leaves to the left or right, and after falling into the feed hopper of the roasting dryer, they enter the roasting dryer. One feeding elevator and feeding conveyor can meet the feeding needs of multiple roasting dryers.

[0008] The drying machine includes a drying machine frame, a furnace body, and a drum. The bottom of the furnace body is a furnace chamber, a furnace door is located at the bottom of the rear end of the furnace body, and a chimney is located at the top of the front end. The drum is placed inside the furnace body, with guide vanes on its inner wall and an opening at its front end. A discharge hopper for the drying machine is located at the opening, and a rolling ring is located on the outer wall of the opening. A pair of support rollers supporting the rolling ring are installed on the drying machine frame. A drum drive device is located at the rear end of the drum. The drum drive device includes a motor and a number of sequentially connected transmission wheels, with the last transmission wheel located at the rear end of the drum. The motor drives the transmission wheels to rotate, thus rotating the drum on the support rollers.

[0009] The pellet burner includes a pellet burner frame and a screw feeding device on it. A pellet feed hopper is located at the rear end of the screw feeding device, and a combustion trough is located at the front end. The combustion trough and the front part of the screw feeding device extend into the furnace chamber from the furnace door. Combustible pellets are placed in the pellet feed hopper and conveyed to the combustion trough by the screw feeding device for ignition, providing heat energy for the drying process of the drying machine.

[0010] Preferably, the furnace body is divided into two parts: a lower furnace body and an upper furnace body, which facilitates equipment processing and assembly.

[0011] Preferably, the furnace body has a fireproof and heat-insulating layer inside its outer shell, which is energy-saving, environmentally friendly, improves the efficiency of drying, and has good safety.

[0012] Preferably, an ash trough separated by a grate is provided below the furnace chamber, and an ash door is provided below the furnace door, so that the ash remaining after combustion falls into the ash trough and is easy to clean.

[0013] Preferably, the pellet burner frame is equipped with an air supply device to supply air into the furnace and improve the combustion effect.

[0014] Preferably, the bottom of the pellet burner frame is equipped with casters to facilitate the movement of the pellet burner.

[0015] Preferably, one of the drive wheels of the roller drive device is equipped with a handle, which allows the roller to be manually rotated in the event of a power outage or other conditions.

[0016] Preferably, a feeding conveyor is also included, located in front of the roasting machine. The feeding conveyor includes a feeding conveyor belt and its drive assembly, and the feeding conveyor belt is located below the discharge hopper of the roasting machine. One feeding conveyor (or several feeding conveyors connected end to end) can receive tea leaves from multiple roasting machines. The drive assembly drives the feeding conveyor belt to transport the tea leaves to the next process, realizing continuous transportation of tea leaves.

[0017] The beneficial effects of this utility model are as follows: 1. It adopts a modular combination design, which can automatically feed and unload multiple roasting and drying machines, and realize continuous cycle roasting and drying of tea leaves without stopping the machine, which meets the needs of continuous automatic processing of tea leaves, improves processing efficiency, greatly reduces manual labor and labor intensity, and meets the production needs of enterprises.

[0018] 2. The rear-entry fire design is adopted, with the pellet burner and the chimney located at the rear and front of the roasting machine, respectively. On the one hand, this enables uniform and precise temperature control, which is the most important process in roasting, ensuring the quality and consistency of the tea. On the other hand, it reduces the footprint of the unit, allowing more roasting machines to be accommodated in the same area, thus improving production efficiency. Attached Figure Description
