Abstract
Description
Technical Field
[0001] This utility model relates to the field of pectin extraction technology, specifically to a reaction vessel for efficient pectin extraction. Background Technology
[0002] Pectin is a type of high-molecular-weight carbohydrate that constitutes cellular structure and is widely found in green plants. Commercial pectin is a white or light yellow powder, odorless, with a slightly fruity aroma. Derived from plant extracts, pectin is completely non-toxic and harmless, typically a white to pale yellow powder with a slightly acidic taste, and soluble in water. In food processing, it possesses excellent gelling, thickening, stabilizing, emulsifying, and suspending properties.
[0003] For example, the authorization announcement number "CN221492502U" is titled "A High-Efficiency Pectin Extraction Reactor." This reactor allows the mixture to reach the required extraction temperature within the feed pipe. After preheating, the mixture enters the stirring chamber, where a stirring device accelerates the mixing of the strong acid and pectin solution. The temperature is maintained by a heating wire within the stirring chamber. However, existing high-efficiency pectin extraction reactors have certain problems in use. After reacting and mixing with the strong acid, the pectin needs to be discharged and filtered while still hot to remove impurities and residues. Conventionally, nylon cloth is used to sieve out impurities in the pectin product. This requires pouring the pectin onto the cloth and manually squeezing it to pass through the gaps. The pectin product is still hot after heating and mixing, making it difficult for workers to directly squeeze and filter it manually. Furthermore, freshly produced pectin is viscous and sticky, resulting in very slow automatic filtration through the nylon cloth, which is detrimental to the extraction efficiency of the high-efficiency pectin extraction reactor. Utility Model Content
[0004] The purpose of this invention is to solve the problems of low extraction efficiency caused by the high temperature of the pectin product after heating and mixing in existing high-efficiency pectin extraction reactors, which prevents workers from directly contacting and manually squeezing the product for filtration, and the fact that the pectin itself is very viscous and sticky when it is freshly produced, resulting in a very slow automatic filtration speed through nylon cloth. Therefore, this invention proposes a high-efficiency pectin extraction reactor.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-efficiency pectin extraction reactor is designed, comprising an outer shell, a controller, and a reactor body. The reactor body is fixedly installed inside the outer shell, and the controller is fixedly installed on the front end of the outer wall of the outer shell. A pectin extraction heating and mixing structure is provided on the upper part of the outer shell, a pectin conveying control structure is provided at the lower end of the reactor body, and a high-efficiency filtration and extraction structure for pectin discharge is provided on the lower side of the outer shell.
[0007] The outer casing of this device is made of aluminum alloy, while the reactor body is made of corrosion-resistant and high-temperature resistant stainless steel. The pectin heating and mixing process can be carried out inside the reactor body. The controller uses a PLC control device, which can control the start-up of the electric heater through circuitry.
[0008] Preferably, the pectin discharge high-efficiency filtration and extraction structure includes a filter frame and a cylinder. The filter frame is fixedly installed on the outside of the outer shell. The cylinder is fixedly installed at the top inside of the filter frame. Multiple hooks are fixedly connected to the inner wall of the filter frame. Nylon filter cloth is movably installed on the inner side of the multiple hooks. A receiving groove is fixedly installed at the bottom inside of the filter frame. A funnel is movably connected to the lower inside of the filter frame.
[0009] This setup utilizes a filter rack placed on the ground outside the housing. The nylon filter cloth is made of fabric, allowing the tip of the hook to pierce through it for secure fixation. The nylon filter cloth is woven from a suitable nylon material. The prepared hot pectin product is poured onto the hung nylon filter cloth through the drainage tube. The gravity of the discharged pectin will press down on the nylon filter cloth, forming an inverted arch shape, and impurities will remain on top of the nylon filter cloth.
[0010] Preferably, the lower end of the funnel is positioned opposite to the top of the receiving trough, and the lower end of the cylinder is positioned opposite to the nylon filter cloth.
[0011] This setup utilizes a power connection to activate the upper cylinder. The cylinder intermittently pushes the lower end against the nylon filter cloth, applying downward pressure to the pectin product and accelerating the filtration process.
[0012] Preferably, the pectin extraction heating and mixing structure includes a motor and a limiting cylinder. The motor is fixedly installed at the top of the outer shell, and a rotating rod is fixedly connected to the lower end of the motor's output shaft. The limiting cylinder is fixedly connected to the inner wall of the reactor body. A stirring blade is fixedly installed on the outer wall of the rotating rod. An electric heater is fixedly installed inside the limiting cylinder. An acid addition pipe is fixedly connected to one side of the top of the outer shell, and a packing pipe is fixedly connected to the other end of the top of the outer shell.
[0013] In this setup, the rotating rod is mounted between the outer shell and the reactor body via bearings. The operator can pour the pectin pre-prepared raw material into the reactor body through the packing tube on one side, and then inject strong acid into the acid injection tube at the other end. The strong acid and the pectin pre-prepared raw material will mix together. The power supply is connected and the motor is started. The motor output shaft can drive the rotating rod to rotate, and the rotating rod can drive the stirring blade at the bottom to mix the various raw materials inside the reactor body. During the mixing process, the electric heater will be powered on to generate heat. The electric heater heats the pectin preparation material to a certain high temperature, and finally, pectin filtrate is produced inside the reactor body.
[0014] Preferably, the lower end of the acid addition pipe is fixedly connected to the interior of the reactor body, and the lower end of the packing pipe is fixedly connected to the interior of the reactor body.
[0015] This setup allows pectin pre-prepared raw materials to be poured into the inside of the reactor via a packing tube on one side, and then strong acid is injected into the acid filling tube at the other end, where the strong acid and pectin pre-prepared raw materials will mix together.
[0016] Preferably, the pectin feeding control structure includes a discharge pipe and a guide pipe. The discharge pipe is fixedly connected to the bottom end of the reactor body, and a discharge valve is fixedly installed at the lower end of the discharge pipe. The guide pipe is fixedly connected to the side wall of the discharge pipe, and a suction pump is fixedly installed on the outside of the guide pipe. A throttling valve is fixedly connected to the other end of the guide pipe.
[0017] This setting involves connecting the discharge pipe to the bottom of the reactor body. By opening the discharge valve, the pectin product can be discharged directly downwards without filtration. The guide pipe is fixedly connected to the side wall of the discharge. Alternatively, the discharge valve can be closed, and the throttle valve and extraction pump can be opened. The extraction pump will transport the discharged pectin product along the horizontal guide pipe into the nylon filter cloth.
[0018] The present invention proposes a high-efficiency pectin extraction reactor, the advantages of which are as follows: the prepared hot pectin product is poured onto the hanging nylon filter cloth through the inlet tube. The gravity of the discharged pectin will press down on the nylon filter cloth, forming an inverted arch shape, and impurities will remain on the nylon filter cloth. The cylinder intermittently pushes the lower end to press on the nylon filter cloth, and the downward pressure applied by the cylinder to the pectin product accelerates the pectin filtration process. The mechanical device accelerates pectin filtration without direct human contact with the high-temperature pectin, and the mechanical driving force can promote the pectin to complete the filtration process more quickly, thus improving the efficiency of pectin extraction by the high-efficiency pectin extraction reactor.

[0034] Working principle:
[0035] The high-efficiency pectin extraction reactor is used for the production and preparation of pectin. In the production of pectin, fruit peel powder needs to be added to water, stirred and dispersed into a pulp, and then the pH value of the pulp is adjusted to 1.5 to 2.5 with a strong acid, namely hydrochloric acid or sulfuric acid. The pulp is then heated, mixed and stirred, and reacted for a period of time to produce pectin product.
[0036] The outer shell 1 is made of aluminum alloy, while the reactor body 3 is made of corrosion-resistant and high-temperature resistant stainless steel. The pectin heating and mixing process can be carried out inside the reactor body 3. The controller 2 is a PLC control device, which can control the start-up of the electric heater 47 by using the circuit.
[0037] The filter rack 61 is placed on the ground outside the outer casing 1. The hooks 65 consist of two rows of opposing stainless steel hooks. The nylon filter cloth 64 is made of fabric, allowing the tips of the hooks 65 to pierce through it for fixation. The nylon filter cloth 64 is woven from 100-mesh nylon material. The prepared hot pectin product is poured onto the hung nylon filter cloth 64 through the drainage tube 55. The gravity of the discharged pectin will press down on the nylon filter cloth 64, forming an inverted arch shape, and impurities will remain on top of the nylon filter cloth 64. Then, connect the power supply and start the upper cylinder 66. The cylinder 66 intermittently pushes the lower end to press against the nylon filter cloth 64. The cylinder 66 applies downward pressure to the pectin product, which speeds up the filtration process. After the impurities are removed, the pectin product flows along the funnel 63 into the receiving tank 62 for storage. The mechanical device speeds up the filtration of pectin without the need for direct human contact with the high-temperature pectin. Moreover, the mechanical driving force can promote the filtration process of pectin more quickly, which improves the efficiency of the pectin extraction reactor.
[0038] The rotating rod 44 is installed between the outer shell 1 and the reactor body 3 via a bearing. The operator can pour the pectin pre-prepared raw material into the reactor body 3 along the packing tube 43 on one side, and then inject strong acid into the acid tube 42 at the other end. The strong acid and the pectin pre-prepared raw material will mix together. The power supply is connected to start the motor 41. The output shaft of the motor 41 can drive the rotating rod 44 to rotate. The rotating rod 44 can drive the stirring blade 45 at the bottom to mix the various raw materials inside the reactor body 3. During the mixing process, the electric heater 47 will be powered on to generate heat. The electric heater 47 heats the pectin preparation material to a certain high temperature. Finally, pectin filtrate is produced inside the reactor body 3.
[0039] The discharge pipe 51 is connected to the bottom of the reactor body 3. By opening the discharge valve 52, the pectin product can be discharged directly downwards without filtration. The guide pipe 55 is fixedly connected to the side wall of the discharge pipe 51. Alternatively, the discharge valve 52 can be closed, and the throttle valve 54 and the extraction pump 53 can be opened.
