Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a multi-stage membrane circulation bone broth concentration production equipment. Background Technology

[0002] In the food processing industry, bone broth, as a nutritious and uniquely flavored ingredient, is widely used in seasonings, convenience foods, and catering ingredients. Bone broth concentration is a crucial step in extending its shelf life, reducing transportation costs, and meeting the formulation requirements of various products.

[0003] With the development of membrane separation technology, membrane concentration methods have gradually been applied in the field of bone broth concentration due to their advantages such as operation at room temperature, low energy consumption, and retention of nutrients and flavor substances. However, existing membrane concentration equipment has some shortcomings when processing bone broth. On the one hand, bone broth contains components such as proteins, fats, colloids, and particulate impurities, which easily form a fouling layer on the membrane surface, leading to a decrease in membrane flux and concentration efficiency. This necessitates frequent membrane cleaning, increasing operating costs and downtime. On the other hand, a single membrane separation process is insufficient to achieve high concentrations, usually requiring multi-stage series or parallel operation. However, existing multi-stage membrane concentration equipment is not rationally designed and controlled, failing to fully utilize the separation efficiency of each membrane stage, resulting in poor overall concentration and unstable product quality.

[0004] Therefore, there is an urgent need to design a multi-stage membrane circulation bone broth concentration production equipment that can effectively reduce membrane fouling, improve concentration efficiency and product quality. Utility Model Content

[0005] The purpose of this invention is to solve the problems of membrane fouling, low concentration efficiency, and unstable product quality in existing membrane concentration equipment, and to propose a multi-stage membrane circulation bone broth concentration production equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage membrane circulating bone broth concentration production equipment, comprising a raw material tank, a primary membrane filtration assembly, a secondary membrane filtration assembly, a tertiary membrane filtration assembly, a concentrate recovery tank, a desalination collection tank, a circulation pipeline, a feed pump, a circulation pump, a cleaning pump, and a control box.

[0007] Furthermore, the raw material tank is used to store the bone broth raw material to be concentrated. The bottom of the raw material tank is connected to the input end of the feed pump through a feed pipe, and the output end of the feed pump is connected to the feed port of the primary membrane filtration module through a pipe.

[0008] Furthermore, the primary, secondary, and tertiary membrane filtration components are sequentially connected via circulation pipelines to form a multi-stage membrane filtration system. The primary membrane filtration component includes a primary membrane housing and a primary ultrafiltration membrane disposed within the housing. The primary ultrafiltration membrane has a pore size of 0.01-0.1 μm and is used to remove large particulate impurities, fats, and some colloidal substances from the bone broth. The concentrate outlet of the primary membrane filtration component is connected to the input end of a circulation pump via a circulation pipeline. The output end of the circulation pump is connected to the inlet of both the primary and secondary membrane filtration components via pipelines. The desalination outlet of the primary membrane filtration component is connected to a desalination collection tank via a pipeline.

[0009] Furthermore, the secondary membrane filtration assembly includes a secondary membrane housing and a secondary nanofiltration membrane disposed within the secondary membrane housing. The pore size of the secondary nanofiltration membrane is 0.001-0.01 μm, used to further remove small molecule impurities and some inorganic salts from the bone broth, while retaining the effective components in the bone broth. The concentrate outlet of the secondary membrane filtration assembly is connected to the input end of a circulation pump via a circulation pipeline, and the output end of the circulation pump is connected to the inlet of the secondary membrane filtration assembly and the inlet of the tertiary membrane filtration assembly via pipelines respectively; the desalination outlet of the secondary membrane filtration assembly is connected to a desalination collection tank via a pipeline.

[0010] Furthermore, the three-stage membrane filtration assembly includes a three-stage membrane housing and a three-stage reverse osmosis membrane disposed within the housing. The pore size of the reverse osmosis membrane is less than 0.0001 μm, used to achieve high-concentration concentration of bone broth. The concentrate outlet of the three-stage membrane filtration assembly is connected to a concentrate recovery tank via a circulation pipeline, and the desalination outlet is connected to a desalination collection tank via a pipeline.

[0011] Furthermore, the circulation pipeline is equipped with pressure and flow sensors to monitor the pressure and flow parameters in the pipeline in real time and transmit the data to the control box. Based on preset process parameters and real-time monitoring data, the control box automatically adjusts the operating frequency of the feed pump and circulation pump, as well as the valve opening of each stage of the membrane filtration assembly, to achieve stable operation and efficient concentration of the multi-stage membrane filtration system.

[0012] Furthermore, the input end of the cleaning pump is connected to the cleaning solution storage tank via a pipeline, and the output end of the cleaning pump is connected to the cleaning port of each stage of the membrane filtration assembly via a pipeline, for chemical cleaning of each stage of the membrane filtration assembly to remove contaminants from the membrane surface and restore the membrane performance.

[0013] Furthermore, the primary membrane filtration assembly, the secondary membrane filtration assembly, and the tertiary membrane filtration assembly all adopt a cross-flow filtration method, with the feed direction parallel to the membrane surface, in order to reduce the deposition of solid particles on the membrane surface and reduce the degree of membrane fouling.

[0014] Furthermore, the circulation pipeline is equipped with a flow meter and a pressure gauge to display the flow rate and pressure values ​​in the circulation pipeline.

[0015] Furthermore, the control box adopts a PLC control system.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By setting up a multi-stage membrane filtration assembly, using ultrafiltration membrane, nanofiltration membrane and reverse osmosis membrane in sequence to filter and concentrate bone broth, different impurities in the bone broth can be removed step by step to achieve a high concentration effect, while retaining the nutrients and flavor substances in the bone broth.

[0017] By connecting the multi-stage membrane filtration system with circulating pipelines, the concentrated wastewater can be recycled and reprocessed, improving feedstock utilization and concentration efficiency. Cross-flow filtration reduces contaminant deposition on the membrane surface, lowers the degree of membrane fouling, and extends membrane lifespan.

[0018] Furthermore, by connecting the output pipe of the concentrate recovery tank to the feed tank, the concentrate produced by the tertiary membrane can be returned to the feed tank for further concentration, thereby further improving the feed utilization rate. Attached Figure Description

The desalination outlet of the three-stage membrane filtration module 4 is connected to the desalination collection tank 6 via a pipeline.

[0024] Reference Figure 2-6As shown in this embodiment: a pressure sensor 71 and a flow sensor 72 are installed in the circulation pipeline 7 to monitor the pressure and flow parameters in the pipeline in real time and transmit the data to the control box 11. The control box 11 is a PLC control box with a human-machine interface. Operators can set concentration process parameters, such as the operating pressure, flow rate, and concentration factor of each membrane stage, and view the equipment operating status and real-time data through the human-machine interface.
