Brick tea pressing method, brick tea pressing device and brick tea mold

Abstract

The invention discloses a brick tea pressing method. The brick tea pressing method comprises the following steps: sleeving, filling tea for the first time, pressurizing for the first time, filling thetea for the second time and the like. A brick tea pressing device comprises a conveyor belt, a pressing machine, a pressing head and platform plates, wherein each platform plate is provided with a guide rod; the pressing head is connected with a movable sliding block and the movable sliding block is connected with a mold locking pressing block; each platform plate is provided with a lateral pressing mold locking mechanism and a mold locking transmission mechanism; a brick tea mold comprises a box body and a bottom plate; a reinforcing frame is arranged at an upper opening of the box body and4 to 6 mold pressure-keeping locks are arranged at the upper edge of the box body; reinforcing ribs are arranged outside two side walls of the brick tea mold. The brick tea mold disclosed by the invention has small thickness; the hollow reinforcing ribs are combined and the bottom of the bottom plate protrudes to disperse pressure, so that the strength is ensured and the weight is also reduced; the volume limitation is overcome and a plurality of pieces of brick tea are pressed and unloaded in the single mode; the plurality of mold pressure-keeping locks are used for keeping a separation plateor a cover plate horizontal so as to prevent the separation plate or the cover plate from being inclined or deformed in a pressing process; the ends of lock bolts are chamfered and an air conveying air pump is connected with a high-pressure air nozzle through an air blowing pipe to clean the lock bolts; an exhausting air pump and an exhausting cover are used for preventing secondary dust fallingand preventing the unsmooth movement of the lock bolts.

Description

technical field [0001] The invention relates to a tea production method, in particular to a brick tea production method, in particular to a tea brick pressing method, a pressing device and a mould. Background technique [0002] Brick tea is a tea leaf shaped like a brick, and it is also a representative type of pressed tea. Brick tea is a semi-finished product made of raw tea by sieving, fanning, cutting, grinding, etc., and then steam-pressed at high temperature into brick-shaped or other types of tea cubes. [0003] Brick tea can be divided into several categories according to the raw materials. Among them, all kinds of black tea are used as raw materials, and the pressed tea of ​​various shapes is made by autoclaving. "Fu brick". Black brick tea, also known as "eight sons", is made from Hunan black hair tea as raw material. The shape is rectangular brick, and the specification is 35cm×18cm×3.5cm. The brick surface is flat and straight, with four distinct corners, unif...

Problems solved by technology

Then there was an automatic lock (for example, application number 201320506067.3, application date 2013.08.20, authorized announcement number CN 203510769 U, authorized announcement date 2014.04.02, mold pressure lock), which greatly improved the degree of automation, but whether it is the transmission steel hoop The existing automatic lock only locks the middle position of the cover plate mold, and the cover plate is prone to tilt or even deformation at both ends, which eventually leads to the phenomenon that one side of the tea brick in the mold is thin and the other is thick, which affects the appearance of the tea brick and quality (different pressing thickness leads to uneven fermentation)

Moreover, because tea powder fragments are extruded during the tea brick pressing process, they are easily stuck and accumulated at the corners of the lock bolt gap of the mold pressure-holding lock (the lock bolt and the bolt hole are in the shape of a cuboid), resulting in unsmooth movement of the lock bolt , unable to spring back, thus affecting the production
