Description

Technical Field

[0001] The utility model relates to the technical field of tea leaf spreading machines, in particular to a tea leaf processing and spreading machine capable of adjusting the angle. Background Art

[0002] During the processing of fresh tea leaves, it is necessary to spread the fresh tea leaves for an appropriate period of time. The nutrients in the fresh leaves will be formed through chemical reactions such as hydrolysis under the action of biological enzymes, which will increase the taste and aroma of the tea leaves. The polysaccharides and proto-pectin in the fresh leaves will also increase under the action of enzymes. Polysaccharides and proto-pectin are sticky, which is beneficial to the shaping of the tea leaves. However, if the fresh leaves are spread improperly, spread too thick, spread for too long, poorly ventilated, or the temperature is too high, the heat generated by the fresh leaves' own respiration will not be dissipated in time, resulting in anaerobic respiration, rising temperature of the fresh leaves, causing the fresh leaves to lose too much water, produce unpleasant odors, and cause the fresh leaves to deteriorate. Therefore, tea leaves are generally spread out in a place without sunlight, and then the tea leaves are dried by external natural wind or wind generated by other fans.

[0003] The existing tea spreading machines generally spread the tea leaves flatly on a supporting plate, and the supporting plate is generally placed horizontally. When the tea leaves on the supporting plate are air-dried, the wind blows toward the tea leaves from a horizontal position, so it is possible that the side away from the wind blowing cannot be fully air-dried, resulting in inconsistent spreading of the tea leaves on the supporting plate, causing problems affecting the efficiency and effect of tea spreading. Therefore, a tea processing and spreading machine with adjustable angle is proposed to solve the above problems. Utility Model Content
