Abstract
Description
Technical Field
[0001] This application relates to the field of tea pigment production, and in particular to a dissolving reaction vessel for tea pigment production. Background Technology
[0002] Tea pigments are a class of plant phenolic pigments, mainly composed of catechins, which are formed through enzymatic or non-enzymatic oxidation of tea polyphenols.
[0003] The process route for obtaining tea pigments using solvent extraction is as follows: tea leaves → solvent extraction → filtration → concentration → primary tea pigment product. The primary tea pigment product often contains non-phenolic substances, mainly soluble sugars (starch, pectin, monosaccharides and disaccharides), amino acids, water-soluble proteins, organic acids and caffeine, etc. The yield of tea pigments is relatively low. In order to increase the content of tea pigments, it is necessary to further remove impurities from the primary tea pigment product.
[0004] Therefore, it is necessary to propose a dissolving reactor for tea pigment production to further remove impurities from the primary tea pigment products, which has become an important technical problem that urgently needs to be solved. Utility Model Content
[0005] This application provides a dissolving reactor for the production of tea pigments, aiming to solve the problem that the primary tea pigment products in the prior art often contain non-phenolic substances, mainly soluble sugars (starch, pectin, monosaccharides and disaccharides), amino acids, water-soluble proteins, organic acids and caffeine, etc., resulting in a relatively low tea pigment yield. In order to increase the content of tea pigments, it is necessary to further remove impurities from the primary tea pigment products.
[0006] To achieve the above objectives, this application proposes a dissolving reactor for tea pigment production, comprising: an inner tank; an outer sleeve disposed on the outer surface of the inner tank, forming a jacket between the outer sleeve and the inner tank; a steam inlet disposed on the outer sleeve and connected to the jacket; a condensate drain port disposed on the outer sleeve and connected to the jacket; a chemical inlet disposed on the inner tank; and a chemical outlet disposed on the inner tank.
[0007] In some embodiments, the device further includes: a stirring drive disposed on the inner tank; and stirring blades disposed on the stirring drive.
[0008] In some embodiments, the device further includes: a temperature measuring hole disposed on the outer casing and communicating with the inner liner; and a sealing gasket disposed on the temperature measuring hole.
[0009] In some embodiments, it also includes:
[0010] The first pressure relief port is located on the outer sleeve and is connected to the jacket.
[0011] Ear base, the ear base is set on the outer peripheral surface of the outer casing.
[0012] In some embodiments, the device further includes: a viewing window disposed at the top of the inner liner; and a viewing light disposed at the top of the inner liner.
[0013] In some embodiments, the device further includes: an alcohol outlet disposed at the top of the inner tank; and a steam rinsing port disposed at the top of the inner tank.
[0014] This application proposes a dissolving reaction vessel for tea pigment production, comprising: an inner tank; an outer sleeve disposed on the outer surface of the inner tank, forming a jacket between the outer sleeve and the inner tank; a steam inlet disposed on the outer sleeve and connected to the jacket; a condensate drain port disposed on the outer sleeve and connected to the jacket; a chemical inlet disposed on the inner tank; and a chemical outlet disposed on the inner tank. The primary tea pigment product and extraction reagent flow into the inner tank through the chemical inlet. Steam enters the jacket through the steam inlet, heating the inner tank and facilitating the dissolution of the primary tea pigment product, thus providing conditions for its reaction with the extraction reagent. The steam condenses within the jacket and exits through the condensate drain. After the reaction is complete, the reacted liquid is discharged through the chemical outlet. The reacted liquid undergoes a drying process to obtain the finished tea pigment product. This reaction equipment can effectively extract and preserve crystalline primary tea pigment products, yielding a finished tea pigment product with higher purity. Attached Figure Description

[0024] See Figure 1 As shown, this application proposes a dissolving reactor for tea pigment production, comprising: an inner tank; an outer sleeve disposed on the outer surface of the inner tank, forming a jacket between the outer sleeve and the inner tank; a steam inlet 15 disposed on the outer sleeve and connected to the jacket; a steam trap port 17 disposed on the outer sleeve and connected to the jacket; a chemical inlet 10 disposed on the inner tank; and a chemical outlet 22 disposed on the inner tank.
[0025] The inner liner includes an elliptical upper end cap 1, an inner liner body 2, and a lower end cap 3, all integrally formed. An inlet 10 is located on the elliptical upper end cap 1, and an outlet 22 is located on the lower end cap 3. The outer casing includes an outer casing body 7 and an outer end cap 6, both integrally formed. The outer casing body 7 is located on the outer circumferential surface of the inner liner body 2, and the outer end cap 6 is located on the outer circumference of the lower end cap 3. The jacket also includes a jacket body 5 and a jacket end cap 4. A steam inlet 15 is located on the outer jacket body 7 and connected to the jacket body 5. A steam trap 17 is located on the outer end cap 6 and connected to the outer end cap 6. A drug inlet 10 is used to discharge the primary tea pigment product and the extraction agent into the inner tank. The primary tea pigment product is in the form of crystals. The primary tea pigment product reacts with the extraction agent in the inner tank. After the reaction is completed, it is discharged from the drug outlet 22. After drying, the finished tea pigment product is obtained.
[0026] Specifically, the primary tea pigment product and extraction reagent flow into the inner tank through inlet 10, while steam enters the jacket through steam inlet 15 to heat the inner tank. This process facilitates the dissolution of the primary tea pigment product and provides conditions for its reaction with the extraction reagent. The steam condenses in the jacket and exits through a steam trap. After the reaction is complete, the reacted liquid is discharged through outlet 22. The reacted liquid undergoes a drying process to obtain the finished tea pigment product. This reaction equipment effectively extracts crystalline primary tea pigment products, resulting in a finished tea pigment product with higher purity.
[0027] The addition of the extractant is mainly to remove soluble sugars (starch, pectin, monosaccharides and disaccharides) from the primary tea pigment product. The extractant can be a combination of oxidases of various soluble sugars, such as one or more combinations of amylase, glucose oxidase, pectin esterase, etc. There are no specific restrictions on the type of extractant, as long as it can effectively remove impurities from the primary tea pigment product.
[0028] The inner tank and outer casing are both made of SUS304 stainless steel. SUS304 stainless steel has excellent mechanical properties and corrosion resistance, enabling the dissolving reactor for tea pigment production to adapt to diverse and harsh operating environments. An insulation layer is also installed inside the outer casing to effectively prevent heat leakage, thereby reducing the energy required for the dissolving reaction.
[0029] See Figure 1As shown, in some embodiments, the system further includes: a stirring drive 13, which is mounted on the inner tank; the stirring drive 13 is a motor with an output end connected to a stirring shaft 12, which is rotatably connected to the inner tank and partially extends into the interior of the inner tank; and the stirring drive 13 drives the stirring shaft 12 to rotate. A stirring blade 11 is also included, mounted on the stirring drive 13. The stirring shaft 12 is positioned on the outer circumferential surface of the inner tank, and the stirring blades 11 are spaced apart. By including the stirring drive 13 and the stirring blades 11, the dissolution efficiency of the initial tea pigment product can be accelerated.
[0030] See Figure 1 and Figure 2 As shown, in some embodiments, the device further includes: a temperature measuring hole 18, which is disposed on the outer casing and communicates with the inner tank; the temperature measuring hole 18 is a stepped hole, including a small hole and a large threaded hole, the small hole communicating with the inner tank and the large threaded hole communicating with the small hole, a temperature probe being screwed into the large threaded hole and extending into the interior of the inner tank through the small hole, measuring the temperature inside the inner tank to ensure stable reaction conditions. A sealing gasket 19 is disposed on the temperature measuring hole 18. The sealing gasket 19 is disposed between the large threaded hole and the small hole to ensure the sealing performance of the temperature probe and prevent leakage of the liquid from inside the inner tank.
[0031] See Figure 1 As shown, in some embodiments, it further includes: a first pressure relief port 16, which is disposed on the outer sleeve and communicates with the jacket; a pressure sensor is disposed inside the first pressure relief port 16, which is used to monitor the steam pressure inside the jacket. When the steam pressure inside the jacket is too high, the first pressure relief port 16 opens to release the steam pressure inside the jacket. An ear seat 8 is disposed on the outer circumferential surface of the outer sleeve. The ear seat 8 is used to fix the inner tube and the outer sleeve to the steel frame, ensuring the stability of the inner tube and the outer sleeve.
[0032] See Figure 1 and Figure 3 As shown, in some embodiments, the device further includes: an ear seat 8, which is disposed at the top of the inner liner; a viewing window 9 rotatably mounted on the top of the elliptical upper head 1, which is bolted to the elliptical upper head 1 and cannot be rotated, allowing the operator to observe the reaction inside the inner liner; and a viewing window light 20, which is disposed at the top of the inner liner. Since there is no light source inside the inner liner, it is difficult for the operator to clearly observe the inside of the inner liner through the viewing window 9. The viewing window light 20 serves to illuminate the interior, enabling the operator to better observe the inside of the inner liner.
[0033] See Figure 1 and Figure 3As shown, in some embodiments, the system further includes: an alcohol outlet 14, located at the top of the inner tank; since the primary tea pigment product is obtained through solvent extraction, it contains impurities such as ethanol. These impurities not only affect the purity of the primary tea pigment product but also have excellent recycling value. After heating the inner tank, the ethanol and other impurities evaporate and are discharged from the alcohol outlet 14 for recycling. A steam rinsing port 21, also located at the top of the inner tank, is used to rinse the inside of the inner tank after the reaction is complete.
[0034] In this embodiment, multiple steam rinsing ports 21 are provided, spaced apart at the top of the elliptical upper head 1. These multiple steam rinsing ports 21 increase the rinsing area, enabling better rinsing of the inner tank. A second pressure relief port is also provided at the top of the elliptical upper head 1, connecting to the inner tank. A pressure sensor is installed inside the second pressure relief port to monitor the internal pressure of the inner tank and prevent excessive pressure inside the inner tank.
[0035] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
