Intelligent vertical-compressing brick tea making machine

Abstract

The invention relates to an intelligent vertical-compressing brick tea making machine. The intelligent vertical-compressing brick tea making machine comprises a frame body, a tea leaf steaming mechanism, a tea leaf conveying mechanism and a brick tea compressing mechanism, wherein the tea leaf steaming mechanism, the tea leaf conveying mechanism and the brick tea compressing mechanism are arrangedon the frame body; a loose tea inlet and a brick tea outlet are arranged on the frame body; the loose tea inlet is in run-through with the tea leaf steaming mechanism, and the tea leaf conveying mechanism communicates with the brick tea compressing mechanism; the brick tea outlet is in run-through with the brick tea compressing mechanism; a steam generating mechanism is further arranged on the frame body; and the steam generating mechanism is connected with the tea leaf steaming mechanism and the tea leaf conveying mechanism separately. The intelligent vertical-compressing brick tea making machine is intelligent, efficient and safe and is high in degree of automation, good in tea leaf quality and more convenient in cleaning; blanking is accurate, tea leaf accumulation does not occur, heatcompensation is present, and heat loss is low; and cartons are free of shrinking, demolding is easy, brick tea is not damaged, and the brick tea is regular and molded after demolded expansion.

Description

technical field [0001] The invention belongs to the technical field of tea production equipment, in particular to an intelligent vertical tea brick pressing machine. Background technique [0002] Brick tea, also known as autoclaved tea, refers to tea leaves that look like bricks. It is also a representative type of pressed tea. Depending on the raw materials and production process, it can be divided into green brick tea, rice brick tea, black brick tea, flower brick tea, Fu brick tea, Kang brick tea, etc. The general brick tea is autoclaved. With the development of tea making technology, the production of Fuzhuan tea is completed by mechanical equipment. However, the existing tea steaming device has a single function and can only complete the tea steaming process. In actual production, the work efficiency is low. On the tea steaming platform, it is in contact with the steam outlet at the bottom, so that the condensed water in the device is easy to drip onto the tea leaves, ...

Problems solved by technology

With the development of tea making technology, the production of Fuzhuan tea is completed by mechanical equipment. However, the existing tea steaming device has a single function and can only complete the tea steaming process. In actual production, the work efficiency is low. On the tea steaming platform, it is in contact with the steam outlet at the bottom, so that the condensed water in the device is easy to drip onto the tea leaves, and the steam from the steam outlet meets the condensed water formed by the tea leaves and mixes with the tea leaves, which will reduce the quality of the tea leaves, and the tea leaves in contact with water will be damaged. Tea stains are formed on the tea steaming platform, which is difficult to clean and takes a long time to clean, which directly reduces work efficiency. On the other hand, small tea leaf stems or tea residues are easy to block the steam outlet, which reduces the tea steaming efficiency and makes the tea soften insufficiently. Far from ideal, difficult to use on a large scale;

[0003] After steam retting, the tea leaves are transported to the pressing process through a conveyor belt or a screw conveyor. However, the existing conveyor belt transportation has poor heat preservation effect, so that the tea leaves entering the pressing process cannot maintain the high temperature state during the steam retting process, which affects the pressing process. Forming effect; because the tea after steam retting is relatively hot and humid, it is easy to stick, the existing screw conveyor is easy to cause the accumulation of tea at the feeding port, and the feeding is not smooth; in addition, the existing conveying process is to ensure the process The continuity of the conveying speed is difficult to control, and the conveyed tea is prone to material accumulation at the entrance of the pressing process, or even overflow

[0004] The existing pressing molding has the following problems: the existing pressing can be mechanized and operated in the flat pressing mode. The surface of the tea bricks in this way is relatively rough, and the tea dregs are easy to fall off the edge. Due to the slow water dispersion, the drying time is longer. The flowering cycle is longer, resulting in a longer entire production cycle, and it is inconvenient to remove the tea bricks after flat pressing; since the mold generally uses a carton, the carton shrinks due to the friction transmitted by the lower pressure; the existing The demoulding process is inconvenient, and it is easy to damage the surface of the carton and even the tea bricks; the brick tea shrinks due to the influence of external force during pressing, but after demoulding, the external force disappears, and the brick tea will expand. The existing mold does not consider this factor, which makes the tea brick demoulding Irregular overall shape after swelling
