AI Technical Summary
The infrared radiation spectrum of existing tea drying equipment is not broad enough to meet the optimal wavelength requirements of tea leaves of different ages or different processing stages.
The device employs staggered installation of quartz glass-cased and metal-cased infrared radiators to create a wide-spectrum infrared radiation. The quartz glass-cased and metal-cased infrared radiators are staggered left and right in the heating device to ensure that the tea leaves can be effectively heated in different wavelength ranges.
It achieves uniform heating and drying of tea leaves, improves heating efficiency, and meets the heating requirements of tea leaves of different ages and at different processing stages.

Abstract
Description
Technical Field
[0001] This utility model relates to tea processing equipment, and more particularly to an infrared radiation heating device for drying tea. Background Technology
[0002] Currently, there are many devices for drying tea using electric infrared radiation heating. Among them, the electric infrared radiation element is either a metal-cased electric infrared radiation tube or a quartz glass-cased electric infrared radiation tube. Since the infrared wavelength radiated by the metal-cased electric infrared tube is longer and the infrared wavelength radiated by the quartz glass-cased electric infrared tube is shorter, using either a metal-cased electric infrared radiation tube or a quartz glass-cased electric infrared radiation tube alone will result in a narrow infrared radiation heating device spectrum.
[0003] The optimal wavelength (frequency) for infrared radiation drying varies depending on the age and maturity of the tea leaves or at different stages of tea processing. Therefore, it is necessary to develop a broadband infrared radiation heating device to better heat and dry the tea leaves. Summary of the Invention
[0004] In view of the different requirements for the optimal wavelength (frequency) of infrared radiation drying for tea leaves of different ages or at different stages of tea processing, this utility model provides an infrared radiation heating device for tea drying.
[0005] An infrared radiation heating device for drying tea leaves includes a drive wheel, a tea conveyor belt, an infrared radiation element housing, a quartz glass outer shell electric infrared radiation tube, and a metal outer shell electric infrared radiation tube.
[0006] The outer casing of the infrared radiation element is located above the tea conveyor belt.
[0007] A quartz glass-cased electric infrared radiator and a metal-cased electric infrared radiator are horizontally mounted on the underside of the outer casing of the infrared radiator, and are installed alternately on the left and right sides.
[0008] Tea conveyor belts are mounted on the left and right drive wheels. The drive wheels rotate clockwise, causing the upper part of the tea conveyor belt to move to the right, and the tea that needs to be heated also moves to the right on the upper part of the tea conveyor belt.
[0009] Because the infrared wavelength radiated by the quartz glass-cased electric infrared tube is shorter, while that of the metal-cased electric infrared tube is longer, the tea leaves are not always heated by short or long infrared wavelengths, thus allowing for better heating and drying of the tea leaves and resulting in a better heating and drying effect.
[0010] Beneficial effects
[0011] This invention involves alternating the installation of metal-cased and quartz-glass-cased infrared radiation tubes, allowing the tea leaves to be heated and dried by broadband infrared radiation, resulting in a better heating and drying effect. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0015] An infrared radiation heating device for drying tea leaves includes a drive wheel 1, a tea conveyor belt 2, an infrared radiation element housing 3, a quartz glass outer shell electric infrared radiation tube 4, and a metal outer shell electric infrared radiation tube 5.
[0016] The infrared radiation element housing 3 is located above the tea conveyor belt 2.
[0017] A quartz glass-cased electric infrared radiator 4 and a metal-cased electric infrared radiator 5 are horizontally mounted on the underside of the outer casing 3 of the infrared radiating element, in a front-to-back direction. The quartz glass-cased electric infrared radiator 4 and the metal-cased electric infrared radiator 5 are installed alternately on the left and right sides.
[0018] A tea conveyor belt 2 is mounted on the left and right drive wheels 1. The drive wheels 1 rotate clockwise, causing the upper part of the tea conveyor belt 2 to move to the right, and the tea that needs to be heated also moves to the right on the upper part of the tea conveyor belt 2.
[0019] Because the infrared wavelength radiated by the quartz glass-cased infrared tube 4 is shorter, while that radiated by the metal-cased infrared tube 5 is longer, the tea leaves are not always heated by short or long infrared wavelengths, thus achieving better heating and drying of the tea leaves and resulting in a better heating and drying effect.
