Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of green brick tea processing, and relates to osmanthus green brick tea pressing equipment and a processing technology. Background Art
[0002] Osmanthus fragrans is the flower of the plant Osmanthus fragrans of the Oleaceae family. It is a flower with ornamental and medicinal value. It is spicy and warm in nature, and it enters the lung, spleen, and kidney meridians. Osmanthus fragrans has the effects of expectoration and cough relief, promoting qi and relieving pain, and promoting blood circulation and removing blood stasis. Xianning is rich in osmanthus resources and has a profound historical and cultural heritage, but its product innovation ability is weak. At present, it is still mainly based on primary processing of osmanthus, and the industry urgently needs to be upgraded. Therefore, combining green brick tea and osmanthus to develop high value-added products will help industrial integration and upgrading.
[0003] The general process of green brick tea is: picking fresh leaves → killing green leaves → rolling → aging → replication → green brick tea loose tea → steaming → brick pressing → drying and repairing bricks → packaging → green brick tea finished product. The combination of green brick tea and osmanthus has problems such as the volatility of the active ingredients of osmanthus, inability to steam, and browning of color. If it is directly mixed with green brick tea loose tea and then steamed and pressed, it is easy to cause the osmanthus to be over-ripe, the active ingredients are seriously lost, and the osmanthus is easy to fall off from the surface of the tea brick. In addition, the active ingredients of osmanthus are easy to volatilize, which greatly reduces the storage time of green brick tea and is very dependent on sealed packaging. Summary of the invention
[0004] The purpose of the present invention is to provide an osmanthus green brick tea pressing device in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the present invention is how to reduce the cost.
[0005] The object of the present invention can be achieved through the following technical solutions: a kind of osmanthus green brick tea pressing equipment, characterized in that it includes a plurality of brick tea molds and a pressing line for continuously pressing tea leaves in the brick tea molds to form tea bricks, the brick tea mold includes a rectangular frame mold, a bottom support plate and a top pressing mold, the bottom support plate is detachably connected to the bottom opening of the rectangular frame mold, the top pressing mold includes a pressing head that can slide longitudinally in the rectangular frame mold, the pressing line includes two symmetrically distributed plywood and a plurality of rollers located between the two plywoods, a material trough allowing the brick tea mold to pass through is formed between the two plywoods, two opposing outer wall surfaces of the rectangular frame mold are respectively provided with a guide roller, the two plywoods are respectively provided with guide rails adapted to the guide rollers, the guide rails include a slope section and a straight section located behind the slope section, the spacing between the slope section and the roller decreases successively with the direction of the material trough, and the spacing between the straight section and the roller is smaller than the spacing between the slope section and the roller.
[0006] Furthermore, the upper surface of the bottom support plate has a "cross"-shaped partition, and the partition includes a first partition in the same plane and a second partition perpendicular to the first partition, and the rectangular frame mold has two notches one adapted to the first partition and two notches two adapted to the second partition, and the outer side of the first partition has a locking portion extending upward to the outside of the outer wall of the rectangular frame mold, and a detachable connector is arranged between the locking portion and the rectangular frame mold.
[0007] Furthermore, the detachable connecting member includes a bolt hole arranged at the locking portion and a locking bolt threaded in the bolt hole. The locking bolt can pass through the bolt hole and press against the outer wall surface of the rectangular frame mold to fix the rectangular frame mold to the bottom support plate.
[0008] Furthermore, the outer wall surface of the rectangular frame mold has a positioning hole corresponding to the locking bolt.
[0009] Furthermore, the inner side of the clamping plate has a guide bar located below the locking portion, and the guide bar can be pressed against the outer wall surface of the rectangular frame mold.
[0010] Furthermore, the partition plates are rotatably connected to the bottom support plate.
[0011] The processing technology of osmanthus green brick tea comprises the following steps: steaming green brick tea loose tea to prepare base tea and surface tea of pressed osmanthus green brick tea, mixing green brick tea loose tea with freeze-dried osmanthus to form middle tea of pressed osmanthus green brick tea; fixing a rectangular frame mold and a bottom supporting plate, putting base tea, middle tea and surface tea into the rectangular frame mold in sequence, closing the top pressing mold, and sending each brick tea mold to a pressing line in sequence one by one; taking out the pressed brick tea mold at the end of the pressing line, drying at room temperature, and demolding to obtain osmanthus green brick tea.
[0012] Furthermore, the weight ratio of the surface tea, the base tea and the middle tea is 1:1:0.8 to 1:1:1.5.
[0013] The differences between this scheme and the prior art are: 1. It adopts a non-powered pressing method, and utilizes the method of pushing the brick tea mold onto the line one by one, and cooperates with the slope section of the guide rail to gradually realize the compression of the tea leaves in the brick tea mold, and realizes preliminary pre-dehydration and cold setting in the straight section. Compared with the traditional pressing method, not only is the equipment cost low, but also the dehydration speed is reduced due to slow pressing, and the rapid loss of the effective ingredients of osmanthus with dehydration is reduced; 2. In this process, osmanthus is only added to the middle tea, and osmanthus is not added to the bottom tea and the surface tea. This method can not only avoid the large-scale exposure of osmanthus, but also reduce the loss of the effective ingredients of osmanthus during the dehydration process, especially the demoulding and dehydration process. In addition, since the middle tea is not steamed, its water content is relatively low, and it is sandwiched between the surface tea and the surface tea. Between the tea and the base tea, during the process of pressing, cold setting and drying, the moisture of the surface tea and the base tea penetrates toward the middle tea, causing the middle tea to slightly mature and stick together into blocks. Compared with traditional green brick tea, the mass proportion of the middle tea in this scheme is significantly reduced. It can also be fumigated by the base tea and the surface tea when they are not steamed in alignment, and the volatilization of the effective ingredients of osmanthus can be greatly reduced. After forming, since the surface tea and the base tea wrap the middle tea, the effective ingredients of osmanthus are sealed for a longer time, which greatly extends the storage time of osmanthus green brick tea; 3. Since the dividing partition divides the whole green brick tea formed by the same brick tea mold into four small pieces that can be broken by hand, it can be broken more easily during brewing. There is no need to cut the tea under appropriate size, just break it. BRIEF DESCRIPTION OF THE DRAWINGS

The top pressing mold 3 includes a pressing head that can slide longitudinally in the rectangular frame mold 1. The pressing line includes two symmetrically distributed clamping plates and a plurality of rollers 4 located between the two clamping plates. A material trough is formed between the two clamping plates to allow the brick tea mold to pass through. The two positive The outer wall surfaces of the pair are respectively provided with a guide roller 31, and the two plywood are respectively provided with a guide rail 5 adapted to the guide roller 31, the guide rail 5 includes a slope section 51 and a straight section 52 located behind the slope section 51, the distance between the slope section 51 and the roller 4 decreases successively with the direction of the material trough, and the distance between the straight section 52 and the roller 4 is smaller than the distance between the slope section 51 and the roller 4; when the brick tea mold is in the pressing line, in the process of moving from the slope section 51 to the straight section 52, the top pressing mold 3 can gradually compress the tea leaves in the rectangular frame mold 1 to achieve compaction.
[0022] The upper surface of the bottom support plate 2 has a "cross" shaped partition plate 21, which includes a first partition plate in the same plane and a second partition plate perpendicular to the first partition plate. The rectangular frame mold 1 has two slots 1 adapted to the first partition plate and two slots 2 adapted to the second partition plate. The outer side of the first partition plate has a locking portion 22 extending upward to the outside of the outer wall of the rectangular frame mold 1, and a detachable connector is provided between the locking portion 22 and the rectangular frame mold 1. The partition plate 21 can realize positioning with the rectangular frame mold 1, reserve a certain overflow gap, and can also preliminarily divide the prepared brick tea into blocks, so that the finished brick tea can be broken into blocks more easily.
[0023] The detachable connection member includes a bolt hole 23 provided at the locking portion 22 and a locking bolt threadedly connected in the bolt hole 23. The locking bolt can pass through the bolt hole 23 and then press against the outer wall surface of the rectangular frame mold 1 to fix the rectangular frame mold 1 to the bottom support plate 2.
