Description

Technical Field

[0001] This utility model relates to the technical field of pear pomace processing, specifically to a pear pomace dietary fiber separation and extraction device. Background Technology

[0002] In the field of food processing and resource recycling, pear pomace, as a major byproduct of pear juice and canned pear production, is rich in dietary fiber, which, due to its functional properties such as "promoting intestinal peristalsis and regulating blood sugar and lipids," has become an important source of food additives and health product raw materials. In the process of separating and extracting dietary fiber from pear pomace, "enzymatic hydrolysis" is a key step. By adding biological enzymes such as cellulase and hemicellulase, the bound components in pear pomace, such as lignin and pectin, are broken down, releasing the dietary fiber from the cell wall structure and laying the foundation for subsequent separation and purification.

[0003] Existing pear pomace dietary fiber separation and extraction devices suffer from low enzyme activity and low contact efficiency in the enzymatic hydrolysis reaction stage. The high viscosity and easy agglomeration of pear pomace make it difficult for the pear pomace at the bottom of the tank to react quickly with the cellulase sprinkled on the top. The core requirement for the enzymatic hydrolysis reaction is "gentle and uniform" stirring, and excessive stirring should not destroy the spatial structure of the enzyme, which would lead to a decrease in enzyme activity. Therefore, it takes a lot of time to completely complete the enzymatic hydrolysis reaction. Utility Model Content

[0004] The purpose of this invention is to provide a pear pomace dietary fiber separation and extraction device. The auger conveys the material up and down through the material hole of the lifting cylinder, and circulates the material at the bottom of the tank to the top, so as to achieve uniform mixing of the material at the bottom.

[0005] Therefore, the technical solution adopted is as follows: A pear pomace dietary fiber separation and extraction device includes a tank body with a cavity in the inner wall. An electric heating coil is wound inside the cavity. The tank body has a stirring mechanism inside, which includes a lifting cylinder inserted into the center of the tank cover and rotatably connected thereto. The lifting cylinder is vertically arranged and has several stirring blades fixed around its bottom end. A coaxial auger is rotatably connected inside the lifting cylinder. Material holes are opened at the upper and lower parts of the side wall of the lifting cylinder. A discharge port is opened at the bottom end of the tank body, and the discharge port is connected to the inlet of the separation mechanism. The separation mechanism is a horizontal spiral centrifuge, and the bottom of the horizontal spiral centrifuge has a solid phase outlet and a liquid phase outlet.

[0006] A further technical solution is that a solenoid valve is installed on the discharge port, and a pump is installed on the other end of the solenoid valve. The output end of the pump is connected to the inlet through a pipe.

[0007] A further technical solution is that a temperature sensor and a pH sensor are embedded in the inner wall of the tank from top to bottom, and a support leg is fixed to the bottom of the tank, with a pressure sensor fixed to the bottom of the support leg.

[0008] A further technical solution is that a number of locking bolts are movably inserted at the outer edge of the can lid, and the locking bolts are threadedly connected to the can body.

[0009] A further technical solution is that the bottom of the can lid is fixed with a receiving cavity, the top end of the lifting cylinder extends into the interior of the receiving cavity and is coaxially fixed with a first bevel gear, the top end of the auger coaxially passes through the first bevel gear and is fitted with a second bevel gear, a third bevel gear meshes between the first bevel gear and the second bevel gear, and the second bevel gear is driven to rotate by a servo motor.

[0010] A further technical solution is that two metering pumps are fixed on the tank lid, and the tops of the two metering pumps are respectively connected to an acid tank and a cellulase addition tank, and the output ends of the two metering pumps extend into the interior of the tank.

[0011] A further technical solution is that the tank cover is also connected to a water inlet pipe and a nitrogen connection pipe, and the nitrogen connection pipe is connected to a one-way valve.

[0012] The beneficial effects of this utility model are: The mixing mechanism's blades agitate the material, while the auger conveys the material up and down through the material holes of the lifting cylinder, circulating and lifting the material from the bottom of the tank to the top, achieving uniform mixing of the material at the bottom. This ensures the uniformity of material decomposition without over-mixing. This pear pomace dietary fiber separation and extraction device uses an electric heating coil in its main body to heat the material inside the tank through a cavity, adapting to the temperature requirements of the extraction process and further improving the efficiency of separation and extraction.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-5 As shown, a pear pomace dietary fiber separation and extraction device includes a tank 101. The inner wall of the tank 101 has a cavity 105. An electric heating coil 106 is wound inside the cavity 105. The tank 101 has a stirring mechanism 2 inside. The stirring mechanism 2 includes a lifting cylinder 208 inserted into the center of the tank cover 201 and rotatably connected thereto. The lifting cylinder 208 is vertically arranged and has several stirring blades 210 fixed around its bottom end. An auger 212 is rotatably connected inside the lifting cylinder 208 and coaxially arranged. The side wall of the lifting cylinder 208 has material holes 209 at the top and bottom. The bottom end of the tank 101 has a discharge port 109. The discharge port 109 is connected to the inlet 304 of the separation mechanism 3. The separation mechanism 3 is a horizontal spiral centrifuge 301. The bottom of the horizontal spiral centrifuge 301 has a solid phase outlet 303 and a liquid phase outlet 302.

[0018] The application heats the tank 101 through the electric heating coil 106 inside the cavity 105 to ensure the required temperature. The stirring blades 210 of the stirring mechanism 2 are only at the bottom of the lifting cylinder 208, so they will not destroy the enzyme activity. The material at the bottom of the tank 101 enters from the material hole 209 at the bottom of the lifting cylinder 208 under the action of the screw conveyor 212, and is discharged from the material hole 209 at the top to participate in the reaction, which improves the reaction efficiency of the material at the bottom.

[0019] A solenoid valve 103 is installed on the discharge port 109, and a pump 104 is installed on the other end of the solenoid valve 103. The output end of the pump 104 is connected to the inlet 304 through a pipeline. The solenoid valve 103 controls the opening and closing of the discharge port 109, and the pump 104 steadily transports the pre-treated material in the tank 101 to the inlet 304 of the horizontal screw centrifuge 301 through the pipeline, realizing automated process connection, reducing manual intervention, and improving production continuity.

[0020] Based on this, such as Figure 4 As shown, a temperature sensor 107 and a pH sensor 108 are embedded in the inner wall of the tank 101 from top to bottom. A support leg 102 is fixed to the bottom of the tank 101, and a pressure sensor is fixed to the bottom of the support leg 102. The temperature sensor 107 and pH sensor 108 monitor the material temperature and pH in real time, providing a basis for adjusting process parameters; the pressure sensor provides feedback on the load-bearing status of the equipment, facilitating the adjustment of the concentration by adding water through the water inlet pipe 205 according to the amount of pear pomace entering; the support leg 102 ensures the stable placement of the tank 101, ensuring a safe and controllable extraction process.

[0021] Several locking bolts 207 are movably inserted at the outer edge of the can lid 201, and the locking bolts 207 are threadedly connected to the can body 101. The locking bolts 207 firmly connect the can lid 201 and the can body 101, ensuring sealing performance and preventing material leakage during heating or stirring, while also facilitating the removal of the can lid 201 to add pear residue.

[0022] like Figure 5 As shown, the bottom of the can lid 201 is fixed with a receiving cavity 214. The top end of the lifting cylinder 208 extends into the interior of the receiving cavity 214 and is coaxially fixed with a first bevel gear 215. The top end of the auger 212 coaxially passes through the first bevel gear 215 and is fitted with a second bevel gear 216. A third bevel gear 213 meshes between the first bevel gear 215 and the second bevel gear 216. The second bevel gear 216 is driven to rotate by a servo motor 206.

[0023] The accommodating cavity 214 provides installation space for the bevel gears. The first bevel gear 215 is fixed to the lifting cylinder 208, enabling power transmission and driving the lifting cylinder 208 and the stirring blade 210 to rotate synchronously. This design is compact and highly efficient. The second bevel gear 216 is fixed to the auger 212, obtaining power through gear meshing to drive the auger 212 to rotate independently, achieving up-and-down circulation of materials and improving mixing uniformity. The third bevel gear 213 simultaneously meshes with the first bevel gear 215 and the second bevel gear 216, enabling a single servo motor 206 to drive the stirring blade 210 and the auger 212 in linkage. This simplifies the transmission structure, reduces energy consumption, and ensures coordinated operation. The servo motor 206 provides stable power for stirring and material lifting, with precise and controllable output speed. It can adjust the stirring and conveying speed according to the material state to adapt to different extraction process requirements.

[0024] Two metering pumps 202 are fixed on the tank lid 201. The tops of the two metering pumps 202 are respectively connected to an acid tank 211 and a cellulase addition tank 203. The output ends of the two metering pumps 202 extend into the interior of the tank body 101. The metering pumps 202 precisely control the amount of acid added to the acid tank 211 and the amount of enzyme added to the cellulase addition tank 203, ensuring the stability of the pH and enzymatic hydrolysis conditions of the material, improving the extraction efficiency and purity of dietary fiber, and avoiding raw material waste. The tank lid 201 is also connected to a water inlet pipe 205 and a nitrogen connection pipe 204. The nitrogen connection pipe 204 is connected to a one-way valve. The water inlet pipe 205 facilitates the addition of water to adjust the pear pomace concentration, while the nitrogen connection pipe 204 allows nitrogen to be introduced into the tank body 101 to isolate air, prevent material oxidation and deterioration, and ensure enzyme activity; the one-way valve ensures unidirectional gas flow, avoids abnormal pressure, and ensures a stable extraction environment.

[0025] Specifically, when using this pear pomace dietary fiber separation and extraction device, firstly, remove the locking bolt 207 to open the tank cover 201 and add pre-treated pear pomace into the tank body 101. Water is added through the water inlet pipe 205, and the weight of the added water is adjusted according to the weight feedback from the pressure sensor at the bottom of the support leg 102 to achieve the specified concentration. Then, after locking the tank cover 201, nitrogen is introduced through the nitrogen connection pipe 204 to isolate air, and a one-way valve is set to ensure stable pressure. The metering pump 202 is started to precisely inject the acid solution from the acid tank 211 and the enzyme preparation from the cellulase addition tank 203 into the tank 101. Simultaneously, the electric heating coil 106 in the cavity 105 is energized for heating, and the temperature sensor 107 and pH sensor 108 monitor the process parameters in real time. A servo motor... 206 starts driving the second bevel gear 216 to rotate, which in turn drives the first bevel gear 215 to rotate via the meshing transmission of the third bevel gear 213. This causes the lifting cylinder 208 to drive the stirring blade 210 to stir and the auger 212 to rotate, lifting the material at the bottom of the tank 101 layer by layer and discharging it from the material hole 209 to the top to achieve circulation mixing. After the enzymatic hydrolysis reaction is completed, the solenoid valve 103 opens, and the pump 104 transports the material through the discharge port 109 and pipeline to the feed port 304 of the horizontal screw centrifuge 301. The centrifuge efficiently separates the solid and liquid phases. The insoluble fiber discharged from the solid phase outlet 303 is sent to the hot air dryer for drying and pulverizing, and the water-soluble solution discharged from the liquid phase outlet 302 is sent to the freeze dryer for granulation, thus completing the extraction and separation of pear pomace dietary fiber.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
