Description

Technical Field

[0001] The invention belongs to the technical field of Pu'er tea fermentation, and in particular relates to a Pu'er tea fermentation plate frame. Background Art

[0002] Pu'er tea is mainly produced in Pu'er City, Lincang City, Xishuangbanna Dai Autonomous Prefecture and other areas of Yunnan Province. Pu'er tea pays attention to brewing skills and drinking art. It can be drunk alone or mixed. Pu'er tea soup is orange-yellow and thick. It is loved by people for its high, sharp and lasting aroma, unique fragrance, rich taste and long-lasting brewing. Pu'er tea needs to be fermented before drinking. Pu'er tea fermentation changes the chemical composition of tea leaves through the action of microorganisms and enzymes, thereby improving the quality of tea leaves, improving the taste, enhancing health functions, and extending the shelf life.

[0003] Traditional large-scale Pu'er tea fermentation is generally carried out in large tea factories, basically fermenting several tons or dozens of tons, with relatively high capital costs, which is unbearable for small-scale fermentation of dozens to hundreds of kilograms. At present, small-scale Pu'er tea fermentation is generally divided into three types. The first fermentation method is to continue fermenting in a basket. This fermentation method is not easy to solve the problem of heat preservation, so the technical requirements are relatively high and it is not easy to popularize; the second fermentation method is to ferment in a wooden frame. Although the fermentation process can ensure the heat preservation effect, the water permeability and air permeability are usually poor, which will cause the wooden board and Pu'er tea to turn black together, and even easily cause Pu'er tea to rot; the third fermentation method is frame-type small pile temperature-controlled fermentation. This fermentation method has relatively high technical requirements and requires electrical control. The cost is relatively high, resulting in a relatively high cost of tea. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0023] Example:

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present embodiment provides a Pu'er tea fermentation plate frame, comprising a rectangular frame body 1 with an opening at the upper end, the rectangular frame body 1 comprising a bottom panel and four side panels, the four side panels are connected end to end to form a quadrilateral frame structure, the quadrilateral frame structure is installed on the bottom panel to form a rectangular frame body 1 with an opening at the upper end, in practice, Pu'er tea to be fermented is placed in the rectangular frame body 1, and then a quilt 2 is laid in the rectangular frame body 1 above the Pu'er tea, so as to cover the Pu'er tea on the bottom surface of the rectangular frame body 1 with the quilt 2, and the heat preservation and air permeability of the quilt 2 are utilized so that the Pu'er tea under the quilt 2 can be kept warm as a whole, so that the inside of the rectangular frame body 1 is Pu'er tea can achieve the effects of heat preservation, moisture retention and ventilation during the fermentation process; the bottom panel and four side panels of the rectangular frame body include an inner heat-insulating, water-permeable and breathable layer 101, a perforated plate partition 102, a wooden frame 103, an outer heat-insulating, water-permeable and breathable layer 104 and an outer shell 105, which are arranged in sequence from the inside to the outside. The inner heat-insulating, water-permeable and breathable layer 101 can keep the fermenting Pu'er tea warm, moisturize and ventilate like the quilt 2, so that the Pu'er tea can be naturally fermented better and the number of operations during the fermentation process can be reduced. An air circulation channel is arranged in the wooden frame 103 to connect the space below the quilt 2 and the space above the quilt 2 through the air circulation channel. The wooden frame 103 and The outer shell 105 cooperates to clamp the outer thermal insulation, water-permeable and breathable layer 104 to ensure the stability of the outer thermal insulation, water-permeable and breathable layer 104 and improve the thermal insulation effect. Among them, the perforated plate partition 102 can separate the inner thermal insulation, water-permeable and breathable layer 101 from the air circulation channel to prevent the inner thermal insulation, water-permeable and breathable layer 101 from filling into the air circulation channel and affecting the circulation effect of the air circulation channel. In practice, the Pu'er tea in the rectangular frame body 1 does not cover the entire height of the rectangular frame body 1. Therefore, after the Pu'er tea is placed, the top of the quilt 2 is generally still located inside the rectangular frame body 1. At this time, the inner thermal insulation, water-permeable and breathable layer 101 can allow air to pass through the inner thermal insulation, water-permeable and breathable layer 10 1. The perforated plate partition 102 and the air circulation channel are connected to the space above the quilt 2, so that the Pu'er tea in the rectangular frame body 1 can achieve a better ventilation effect, thereby reducing or avoiding the possibility of the Pu'er tea turning black and rotting during the fermentation process; a water outlet pipe 107 is arranged on the shell 105 of at least one side panel, and the water inlet of the water outlet pipe 107 is connected to the air circulation channel to ensure water permeability. It should be noted that the number of water outlet pipes 107 can be set according to actual conditions. Generally, the water outlet pipe 107 is arranged at the lower part of the side panel, and the water outlet pipe 107 can also be arranged at the upper part of the side panel. The water amount when adding water can be controlled through the water outlet pipe 107 at the upper part of the side panel.

[0025] The present invention provides a Pu'er tea fermentation plate frame. In practice, the Pu'er tea to be fermented can be placed at the bottom of a rectangular frame body 1, and then a quilt 2 is covered on the Pu'er tea, so that the Pu'er tea can be kept warm, moisturized and breathable by the quilt 2, and the water outlet pipe 107 is combined to ensure the water permeability effect, while ensuring the fermentation effect, reducing the possibility of the Pu'er tea turning black and rotting due to poor air permeability; on the basis of the above, the bottom panel and four side panels of the rectangular frame body all include an inner heat-insulating, water-permeable and air-permeable layer 101, a perforated plate partition 102, a wooden board frame 103, an outer heat-insulating, water-permeable and air-permeable layer 104 and an outer shell 105, which are arranged in sequence from the inside to the outside, and the outer heat-insulating, water-permeable and air-permeable layer 104 can enhance the heat-insulating effect, and an air circulation channel is arranged in the wooden board frame 103, and the perforated plate partition 102 can separate the inner heat-insulating, water-permeable and air-permeable layer 101 from the air circulation channel to ensure air circulation. The wooden frame 103 cooperates with the outer shell 105 to clamp the outer thermal insulation, water-permeable and breathable layer 104 to ensure the stability of the outer thermal insulation, water-permeable and breathable layer 104 and improve the thermal insulation effect. On this basis, the inner thermal insulation, water-permeable and breathable layer 101 directly contacts the Pu'er tea to be fermented, so that the Pu'er tea can be naturally fermented better while achieving the thermal insulation and moisturizing effects, reducing the number of operations during the fermentation process, and the Pu'er tea placement space under the quilt 2 can be connected to the space above the quilt 2 through the inner thermal insulation, water-permeable and breathable layer 101, the perforated plate partition 102 and the air circulation channel, so as to further improve the air permeability, thereby better reducing or avoiding the possibility of Pu'er tea turning black and rotting during the fermentation process.
