Description

Technical Field

[0001] This utility model relates to the field of black tea processing technology, and in particular to a black tea melting device. Background Technology

[0002] As is well known, black tea contains substances such as theaflavins, proteins, and amino acids. When the concentrated black tea liquor is cooled, theaflavins react with the hydrogen bonds of amino acids or proteins, condensing into large, insoluble molecules, causing the concentrated liquor to appear cloudy, commonly known as "tea cream." In the production process of instant black tea powder or instant black tea concentrate, "tea cream" must be removed by chemical or physical methods to improve the clarity of the product. Existing chemical methods for removing "tea cream" usually involve adding alkali to the tea liquor and simultaneously introducing oxygen. This breaks the hydrogen bonds of the tea cream, converting it into a soluble substance. During the conversion process, oxygen is introduced into the concentrate and assists the reaction between the tea cream and the alkali. This reaction process takes a certain amount of time, and some oxygen escapes upwards and is wasted, and it mostly comes into contact with the liquid near the vent, failing to diffuse fully within the liquid, thus affecting the conversion efficiency of the tea cream. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a black tea melting device.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a black tea solvent conversion device, comprising a reaction chamber, a drain valve provided at the bottom rear side of the reaction chamber, a retaining plate fitted at the center of the top of the reaction chamber, a Y-shaped infusion tube fitted and fixed at the center of the retaining plate, metering tanks fixedly connected to the left and right ends of the top of the Y-shaped infusion tube, a base fitted and connected to the rear of the metering tank, the bottom of the base fixedly connected to the retaining plate, the metering tank located on the left side of the base storing concentrated liquid, the metering tank located on the right side of the base storing alkaline solution, a pressure valve fitted and provided on the top left side of the reaction chamber, a gas storage tank connected to the top of the pressure valve, the gas storage tank storing oxygen, a gas delivery pipe fixedly connected to the center of the bottom of the pressure valve, the bottom of the gas delivery pipe positioned below the inner side of the reaction chamber and its end extending to the right, a vent provided on the top left side of the reaction chamber, the vent located to the right of the pressure valve, and a circulation pipe provided inside the vent. The outer side of the circulation pipe is fixedly connected to the reaction chamber. The lower right end of the circulation pipe extends to the left into the interior of the reaction chamber and is fixedly connected thereto. An air pump is installed in the middle of the right side of the circulation pipe. A semi-circular drainage plate is mounted on the outer side of the bottom end of the Y-shaped infusion pipe. A flow divider cone is fixedly connected vertically at the center of the inner side of the semi-circular drainage plate. The flow divider cone is located directly below the Y-shaped infusion pipe. Several support rods are fixedly arranged in a ring at the bottom of the semi-circular drainage plate. The bottom ends of the support rods are all fixedly connected to the reaction chamber. By setting the gas infusion pipe to be inserted directly into the bottom of the reaction chamber and cooperating with the circulation pipe and air pump to circulate and mix, the reaction solution can be continuously contacted with oxygen and mixed to fully dissolve, thereby accelerating the dissolution efficiency of the tea cream. In addition, by setting the Y-shaped infusion pipe, cooperating with the semi-circular drainage plate and the flow divider cone inside it to simultaneously mix and introduce the concentrated solution and the alkali solution, they are dispersed and mixed in a circular manner in the reaction chamber, thereby increasing the dispersion range of the subsequently introduced solution and thus accelerating the reaction rate of both, improving the overall dissolution efficiency.

[0005] As a further description of the above technical solution: the air pump is symmetrically provided with pads on the upper and lower sides. The left side of each pad is fixedly connected to the reaction chamber, and the opposite side of each pad is engaged with the air pump from the top and bottom. This clamps and fixes the air pump while limiting its vertical position, ensuring the stability of its output direction.

[0006] As a further description of the above technical solution: a pH meter is fitted into the top right side of the reaction chamber, and a detection probe is set at the bottom center of the pH meter. The bottom end of the detection probe extends into the inner bottom of the reaction chamber to facilitate real-time monitoring of the pH value of the mixture.

[0007] As a further description of the above technical solution: each metering tank has a top cover that can be rotated and locked at the center of its top, which facilitates continuous replenishment of concentrated liquid for dissolution.

[0008] As a further description of the above technical solution: the bottom of the reaction chamber is fixedly connected to an anti-slip base to maintain the overall stability during the reaction process.

[0009] This utility model has the following beneficial effects:

[0010] In this invention, by setting a gas delivery pipe that is directly inserted into the bottom of the reaction chamber and combined with a circulation pipe and a gas pump for circulating introduction and mixing, the reaction solution can be continuously in contact with oxygen for thorough dissolution, thereby accelerating the dissolution efficiency of tea cream. In addition, by setting a Y-shaped infusion pipe in conjunction with a semi-circular guide plate and a flow divider cone inside, the concentrated liquid and alkali solution are simultaneously mixed and introduced, while being dispersed and mixed in a circular manner within the reaction chamber, thereby increasing the dispersion range of the subsequently introduced solution and accelerating the reaction rate of both, thus improving the overall dissolution efficiency.

[0019] A semi-circular drainage plate 15 is mounted on the outer side of the bottom of the Y-type infusion tube 3. A flow divider cone 16 is vertically fixed to the center of the inner side of the semi-circular drainage plate 15. The flow divider cone 16 is located directly below the Y-type infusion tube 3.
