Constant-temperature type tea frying device

Abstract

The invention relates to the technical field of processing of tea leaves, and discloses a constant-temperature type tea frying device. The constant-temperature type tea frying device comprises a machine frame, wherein a frying pan is arranged on the machine frame; a hollow rotating shaft is rotatably connected to the machine frame; a wind supplying tank and a wind chamber which communicates with the wind supplying tank are arranged on the machine frame; a turbine which is coaxial to the rotating shaft is rotatably connected to the wind chamber; an exhaust hole is formed in the wind chamber; anannular ring which communicates with the wind chamber is rotatably connected to the rotating shaft in a sleeving manner; a first air hole is formed in the annular ring; a second air hole which is used for communicating with the first air hole is formed in the rotating shaft; hollow stirring vane boards which communicate with the rotating shaft are fixedly connected to the rotating shaft; heatingsources of which the types are the same are respectively arranged on the inner layers of the stirring vane boards and the inner layer of the frying pan; a controller for controlling the operation of the heating sources is mounted on the machine frame; and third air holes are formed in each stirring blade plate. According to the constant-temperature type tea frying device disclosed by the invention, the heating time of the heating source is controlled by the controller, so that the stir-frying temperature can be adjusted; tea leaves can be sufficiently stirred by the stirring vane boards, so that the tea leaves can be uniform in quality; and besides, the situation that the tea leaves are adhered can be avoided through wind blowing, so that the situation that the tea leaves are broken is avoided.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a constant temperature tea frying device. Background technique [0002] Fried tea usually refers to the frying process in the process of tea processing. It is a method of wilting tea leaves in a frying pan with low heat. This process has a certain impact on the quality of tea leaves. The traditional method of frying tea is to put the tea leaves in a frying pan, and then stir-fry the tea leaves with a hand-held spatula. This method cannot be continuously stir-fried, which will easily lead to uneven stir-frying, resulting in different colors of tea leaves or overheating. And tealeaves sticks on spatula easily, need manual cleaning, has increased labor intensity, has reduced the efficiency of frying tea. [0003] In order to solve the above problems, Chinese patent (CN104171077B) discloses a device for frying tea, which includes a frying pan and a rotating shaft driven by a ...

Problems solved by technology

[0004] Although the above-mentioned patented scheme solves the deficiencies in the traditional way of frying tea, there are still some points to be improved in this scheme: 1. The stir-fry brush is realized to rotate through the rotating shaft, the support rod and the fixed shaft, and the three stir-fry brushes are used to rotate. The brush cannot actively rotate around its center of circle, and only when it touches the tea leaves, that is, when it interacts with the tea leaves, can it passively rotate around its circle center, resulting in unsatisfactory stirring effect of the stir-frying brush on the tea leaves; 2. In the device The temperature of the fried tea is uncontrollable; 3. When the cleaning brush is scraping off the sticky tea leaves on the stir-frying brush, it will be squeezed because the cleaning brush and the stir-frying brush are offset. The tea on the brush breaks and destroys the quality of the tea
