Description

Technical Field

[0001] This utility model relates to tea processing machinery, and more particularly to an automatic multi-layer infrared roasting machine for tea that combines gas and electricity. Background Technology

[0002] There are many infrared tea roasting machines available now, but they are either gas-fired or electric. Gas-fired infrared roasting machines can only be made into single-layer structures. If multiple layers are used, the upper layer is difficult to install and is prone to contaminating the tea.

[0003] Electric infrared roasting machines have several drawbacks. First, they require a large amount of electricity, which is insufficient in many places during the tea season. Second, they lack the advantage of gas-fired infrared radiation roasting, which is closer to charcoal roasting of tea leaves. Summary of the Invention

[0004] To address the shortcomings of existing tea infrared roasting machines, such as gas-fired machines which easily contaminate tea leaves and electric machines which have high power consumption and lack the advantages of gas-fired infrared radiators that are closer to charcoal roasting, this invention provides a combined gas and electric automatic multi-layer infrared tea roasting machine.

[0005] An automatic multi-layer infrared roasting machine for tea, combining gas and electricity, includes a feeding hopper, a tea lifting mechanism, a tea spreading mesh conveyor, an electric infrared radiator, a gas infrared radiator, a vibrating tea outlet trough, a tea outlet bucket, a frame, and an automatic control system. It adopts a combination of electric and gas infrared radiators for heating, and has a three-layer structure. The top two layers are heated by electric infrared radiators, and the bottom layer is heated by gas infrared radiators.

[0006] The right side of the roasting machine is the heating and conveyor section, which, from top to bottom, consists of an electric infrared radiator, a tea spreading mesh conveyor, an electric infrared radiator, a tea spreading mesh conveyor, a gas infrared radiator, and a vibrating tea outlet trough.

[0007] The left side of the roasting machine has a feeding hopper and a tea lifting mechanism.

[0008] The tea hopper is located on the lower right side of the vibrating tea trough.

[0009] The vibrating tea trough is installed on the frame.

[0010] The tea leaves to be roasted are lifted from the hopper by the tea lifting mechanism to the top left of the tea spreading mesh conveyor, and then transported to the right by the tea spreading mesh conveyor while being roasted by the electric infrared radiator.

[0011] When the tea leaves are conveyed to the right end by the upper tea spreading mesh conveyor, they automatically fall to the right end of the lower tea spreading mesh conveyor and are then conveyed to the left by the lower tea spreading mesh conveyor, while being roasted by the lower electric infrared radiator.

[0012] When the tea leaves are conveyed to the left end by the tea spreading mesh conveyor below, they automatically fall to the left end of the vibrating tea trough and are roasted by the gas infrared radiator. The tea leaves vibrate and move to the right in the vibrating tea trough, and the roasted tea leaves automatically fall into the tea outlet.

[0013] The temperature of the electric infrared radiator and the gas infrared radiator, as well as the conveyor speed of the tea spreading mesh belt, can be adjusted according to the size and age of the tea leaves.

[0014] This gas and electric combined multi-layer infrared roasting machine is equipped with an automatic control system, which automatically completes the entire operation, including the lifting and moving speed of the tea leaves and the final output to the tea outlet.

[0015] Beneficial effects;

[0016] The beneficial effects of this gas-powered and electric combined automatic multi-layer infrared tea roasting machine:

[0017] 1. It adopts a combination of electric infrared radiators and gas infrared radiators for heating, which has the advantages of both electric infrared radiator heating and gas infrared radiator heating.

[0018] 2. It adopts a three-layer structure, which has a small footprint and high baking efficiency.

[0019] 3. Gas and electricity are converted into gas infrared radiation and electric infrared radiation respectively to dry tea leaves, resulting in high thermal efficiency, high penetration of dried tea leaves, and good quality dried tea leaves.

[0020] 4. The lower layer uses gas-fired infrared radiation baking, which is similar to the characteristics of charcoal baking of tea, resulting in high quality.

[0021] 5. The power consumption is relatively low, making it suitable for situations where power is insufficient during the tea season in many places. Attached Figure Description
