Solar drum-type tea leaf fixation machine

Abstract

The invention discloses a solar drum-type tea leaf fixation machine in the field of tea leaf processing equipment. The machine comprises a drum body, a bracket, a motor driving the drum body to rotate, an insulation drum and a solar electromagnetic panel, wherein a feed port is formed in the drum body; the insulation drum is arranged on the bracket, and comprises an inner drum and an outer drum; a sand grain layer filled with sand grains is arranged between the inner drum and the outer drum; the solar electromagnetic panel is arranged on the surface of the outer drum; the drum body is movably arranged in the inner drum in a sleeving manner; and the feed port is located at the end of the drum body. In the scheme, the solar electromagnetic panel absorbs solar energy and converts the solar energy into heat energy, but if the heat energy is directly transferred to the drum body, the drum body can only be locally heated, and heat cannot be stored for a long time, so that the insulation drum provided with the inner drum and the outer drum is arranged in the scheme, the sand grain layer is arranged between the inner drum and the outer drum, the sand grains are filled in the sand grain layer, temperature rise is rapid after the sand grains are heated, temperature dissipation is slow, and an insulation effect is good.

Description

technical field [0001] The invention relates to the field of tea processing equipment, in particular to a solar drum type tea greening machine. Background technique [0002] Fixing is the most important process in tea processing and a key process to improve the quality of tea. It mainly destroys and passivates the activity of oxidase in fresh tea leaves by high temperature, inhibits the enzymatic reaction of tea polyphenols in fresh tea leaves, makes the tea leaves soft, easy to knead and shape, and emits green odor at the same time, and promotes the formation of good tea leaves. aroma. [0003] Tea greening is divided according to the heating method, including fuel heating, electric heating and microwave heating. Coal is generally used for fuel heating. Coal is a non-renewable resource. A large amount of use will cause a large consumption of coal resources, and in coal-fired During the process, harmful gases such as carbon monoxide and sulfur dioxide will be produced, as ...
