Description

Technical Field

[0001] The utility model belongs to the technical field of Pu'er tea fermentation, in particular to a distributed round hole ventilation groove for Pu'er tea fermentation. Background Art

[0002] Pu'er tea is a special fermented tea, and its fermentation process is crucial to the quality and taste of the tea. Good air permeability is required during the fermentation process. Therefore, the ventilation trough is widely used in various Pu'er tea fermentation processing occasions, and can effectively improve the fermentation quality and taste of Pu'er tea. At the same time, its simple structure and easy manufacturing and installation also make the ventilation trough have broad application prospects in the field of Pu'er tea production.

[0003] Generally, a distributed round hole ventilation trough for Pu'er tea fermentation is adopted. There are several ventilation holes on the base. These ventilation holes can ensure that air can smoothly enter the bottom of the fermentation pile and provide sufficient oxygen for the tea leaves. However, in the early stage of fermentation, tea leaves need sufficient oxygen to respire, promote the reproduction of microorganisms and the start of the fermentation process. Therefore, the air permeability requirement at this time is relatively high, and it is necessary to ensure that there is sufficient air circulation inside the tea pile. In the later stage of fermentation, the quality and taste of the tea leaves are basically stable. At this time, it is necessary to appropriately reduce the air permeability to reduce the contact between the tea leaves and the external environment, prevent over-fermentation and quality degradation, and the general distributed round hole ventilation trough for Pu'er tea fermentation cannot change the air permeability of the device as the fermentation process changes. For this reason, we designed a distributed round hole ventilation trough for Pu'er tea fermentation to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a distributed circular hole ventilation groove for Pu'er tea fermentation, so as to solve the problem in the above background technology that the air permeability cannot be changed according to demand at different stages of the Pu'er tea fermentation process.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A distributed circular hole ventilation trough for Pu'er tea fermentation comprises: a fermentation box body, the bottom of which is provided with a plurality of circular ventilation holes communicating with the interior; a rectangular connecting plate, the rectangular connecting plate being arranged at the bottom of the fermentation box body, the top of which is fixedly connected with a plurality of limiting cylinders matching the circular ventilation holes.

[0007] As a further solution of the present invention: two limiting round rods are fixedly connected to the bottom of the fermentation box body, and the rectangular connecting plate is slidably connected to the outer walls of the two limiting round rods, and the bottoms of the two limiting round rods are fixedly connected to a rectangular bar, and a single-rod piston hydraulic cylinder is installed at the bottom of the rectangular bar, and the output end of the single-rod piston hydraulic cylinder passes through the top of the rectangular bar and is fixedly connected to a driving round rod, and the top of the driving round rod is fixedly connected to the bottom of the rectangular connecting plate.

[0008] As a further solution of the present invention: the ventilation holes are staggeredly arranged at the bottom of the fermentation box body, and the limiting cylinders are spaced and corresponding to the ventilation holes.

[0010] As a further solution of the present invention: a conical sealing strip is fixedly connected to the inner side of the vent hole corresponding to the limiting cylinder, and the inner side of the conical sealing strip is set to be conical.

[0011] Beneficial effects of the utility model:

[0012] 1. The present invention uses the coordination of the limiting cylinder and other parts to enable the limiting cylinder 3 to move upward. When the end of part of the limiting cylinder 3 enters the inner side of the vent hole 2, the single-rod piston hydraulic cylinder 7 stops moving. At this time, the limiting cylinder 3 blocks a small part of the vent hole 2, thereby increasing the airtightness of the device, reducing the contact between tea leaves and oxygen, preventing excessive fermentation of tea leaves and the deterioration of tea quality, and thus improving the overall practicality of the device.

[0013] 2. The utility model, through the coordination of the ventilation holes and other parts, inserts the shorter limiting cylinder 3 into the interior of the ventilation holes 2, thereby blocking most of the ventilation holes 2, further reducing the air permeability of the device and improving the airtightness of the device, thereby achieving the goal of preventing the quality of tea from being deteriorated due to excessive fermentation during the fermentation stage, and improving the fermentation effect of the device;

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Please refer to Figure 1-4 The top of the driving rod 8 is fixedly connected to the bottom of the rectangular connecting plate 4, and the top of the driving rod 8 is fixedly connected to the bottom of the rectangular connecting plate 4. The plurality of ventilation holes 2 are staggered at the bottom of the fermentation box body 1, and the limiting cylinder 3 corresponds to the ventilation holes 2 at intervals. The length of the limiting cylinder 3 is arranged alternately in a high and low cycle.

[0024] In this embodiment: the single-rod piston hydraulic cylinder 7 is controlled by an external PLC controller, and the single-rod piston hydraulic cylinder 7 is extended by the external PLC controller, and the extension action of the single-rod piston hydraulic cylinder 7 has two strokes. Since the extension control of the single-rod piston hydraulic cylinder 7 is controlled by the PLC controller and it is a prior art, it is not described in detail in this solution. After the staff has rolled the Pu'er tea, when it needs to be fermented, the Pu'er tea can be poured into the inner side of the fermentation box body 1, and the tea leaves are spread together for wet pile fermentation. At the beginning of the fermentation stage, all the air holes 2 are in an open state, and the tea leaves can be fully ventilated to allow the tea leaves to be exposed to oxygen in the air. Better contact promotes the reproduction of microorganisms and the start of the fermentation process. As time goes by, when it reaches the middle stage of fermentation, the staff starts the single-rod piston hydraulic cylinder 7. During the start and stop process of the first stroke of the single-rod piston hydraulic cylinder 7, the output end of the single-rod piston hydraulic cylinder 7 drives the round rod 8 to move upward, thereby causing the limiting cylinder 3 to move upward. When the end of part of the limiting cylinder 3 enters the inner side of the air permeable circular hole 2, the single-rod piston hydraulic cylinder 7 stops moving. At this time, a small part of the air permeable circular hole 2 is blocked by the limiting cylinder 3, thereby increasing the airtightness of the device, reducing the contact between tea and oxygen, preventing the tea from over-fermenting and causing the quality of the tea to deteriorate, thereby improving the overall practicality of the device.

[0025] When the fermentation process of the tea leaves reaches the later stage, the single-rod piston hydraulic cylinder 7 performs the second stroke start and stop process. Since the quality and taste of the tea leaves have been basically stable, it is necessary to further reduce the air permeability to reduce the contact between the tea leaves and the external environment. At this time, the single-rod piston hydraulic cylinder 7 continues to move upward, thereby driving the limiting cylinder 3 to move upward, so that the shorter limiting cylinder 3 is also inserted into the interior of the air permeable circular hole 2, thereby blocking most of the air permeable circular hole 2, further reducing the air permeability of the device and improving the airtightness of the device, thereby achieving that the tea leaves will not be over-fermented during the fermentation stage, resulting in a decline in the quality of the tea leaves, thereby improving the fermentation effect of the device.

[0026] Please refer to Figure 3 The inner side of the vent hole 2 corresponding to the limiting cylinder 3 is fixedly connected with a conical sealing strip 9, and the inner side of the conical sealing strip 9 is set as a conical

[0027] In this embodiment: when the single-rod piston hydraulic cylinder 7 pushes the limiting cylinder 3 into the air-permeable circular hole 2, the end face of the limiting cylinder 3 first contacts the bottom face of the conical sealing strip 9, and gradually squeezes the conical sealing strip 9 during the upward movement until the end face of the limiting cylinder 3 is flush with the inner bottom face of the fermentation box body 1. At this time, the extrusion force reaches the maximum. At this time, the conical sealing strip 9 will be tightly attached to the outer wall of the limiting cylinder 3 under the action of the extrusion force, thereby improving the sealing effect of the limiting cylinder 3, thereby improving the overall practicality of the device.

[0028] Working principle:

[0029] Pour Pu'er tea into the inner side of the fermentation box body 1, spread the tea leaves together, and carry out wet pile fermentation. At the beginning of the fermentation stage, all the air holes 2 are in an open state, which can fully ventilate the tea leaves, so that the tea leaves can better contact with the oxygen in the air, promote the reproduction of microorganisms and the start of the fermentation process. As time goes by, in the middle stage of fermentation, the staff starts the single-rod piston hydraulic cylinder 7. During the start and stop process of the first stroke, the output end of the single-rod piston hydraulic cylinder 7 drives the driving rod 8 to move upward, thereby causing the limiting cylinder 3 to move upward. When the end of part of the limiting cylinder 3 enters the inner side of the air hole 2, the single-rod piston hydraulic cylinder 7 stops moving. At this time, a small part of the air hole 2 is blocked by the limiting cylinder 3, thereby increasing the airtightness of the device and reducing the contact between the tea leaves and oxygen.

[0030] When the fermentation process of the tea leaves reaches the late stage, the single-rod piston hydraulic cylinder 7 performs the second stroke start-stop process. Since the quality and taste of the tea leaves have basically stabilized, it is necessary to further reduce the air permeability to reduce the contact of the tea leaves with the external environment. At this time, the single-rod piston hydraulic cylinder 7 continues to move upward, thereby driving the limiting cylinder 3 to move upward, so that the shorter limiting cylinder 3 is also inserted into the interior of the air permeable circular hole 2, thereby blocking most of the air permeable circular hole 2, further reducing the air permeability of the device and improving the airtightness of the device.

[0031] When the single-rod piston hydraulic cylinder 7 pushes the limiting cylinder 3 into the air-permeable circular hole 2, the end face of the limiting cylinder 3 first contacts the bottom surface of the conical sealing strip 9, and gradually squeezes the conical sealing strip 9 during the upward movement until the end face of the limiting cylinder 3 is flush with the inner bottom surface of the fermentation box body 1. At this time, the extrusion force reaches the maximum, and the conical sealing strip 9 will be tightly attached to the outer wall of the limiting cylinder 3 under the action of the extrusion force.
