Peptide Extraction Production Line: Structure, Principles and Core Characteristics
I. Structural Composition of the Peptide Extraction Production Line
The Jinzong peptide extraction production line adopts a modular design, where individual unit equipment operates in synergy to cover the entire process from raw material handling to finished product output. Its core structure can be divided into six major systems, each with distinct functions and tight interconnections.
(I) Raw Material Pretreatment System
This system serves as the foundational stage for peptide extraction. Its core function is to remove impurities from the raw materials and disrupt cellular structures to create optimal conditions for subsequent extraction. Key equipment includes cleaning machines, crushers, homogenizers, low-temperature degreasing equipment, and centrifugal separators. Raw materials are sourced from a wide range, including animal tissues (bovine bone, fish skin, snail mucus), plants (soybean, wheat, edible fungi), and microorganisms. Initially, impurities such as silt and microorganisms are removed via the cleaning machine. Materials are then crushed to a particle size below 100 mesh using a crusher. Ultrasonic homogenization technology is employed to disrupt cell walls and release peptide molecules. For raw materials with high-fat content, low-temperature degreasing equipment is used to remove fat, preventing negative impacts on extraction purity. Special raw materials like snail mucus undergo centrifugal separation at 3000-5000 rpm to obtain a purified raw material solution. Throughout this process, a low-temperature environment of 0-4°C is maintained, or antioxidants like vitamin C are added to prevent premature degradation of peptide substances.
(II) Core Extraction and Conversion System
As the central unit of the production line, this system is responsible for converting proteins from the raw materials into small-molecule peptides. The primary equipment is the intelligent enzymatic hydrolysis tank, supplemented by supercritical fluid extraction (SFE) equipment for thermolabile peptides. The enzymatic hydrolysis tank integrates functions such as stirring, centrifugation, and temperature/pressure/pH regulation. It allows for the addition of specific proteases like trypsin or papain, based on raw material characteristics, to achieve targeted protein hydrolysis. The SFE equipment utilizes carbon dioxide as a medium. Under supercritical conditions (pressure ≥74 bar, temperature ≥31°C), it leverages the high solvency and permeability of the supercritical fluid to extract peptide molecules. This method is suitable for extracting thermolabile components like melittin.
(III) Separation and Purification System
This system is used to remove macromolecular impurities, salts, and pigments from the extraction solution, thereby enhancing the purity of the peptide product. It primarily consists of plate and frame filters, membrane separation equipment (ultrafiltration, nanofiltration), ion exchange chromatography equipment, and decolorization equipment. The extraction solution first undergoes coarse filtration via the plate and frame filter to remove solid impurities. Subsequently, ultrafiltration membranes (pore size 1-10 kDa) are used to screen for target peptide segments based on molecular weight, separating macromolecular proteins and salts. For pharmaceutical-grade peptide products, further purification using ion exchange chromatography or gel filtration chromatography equipment is required to achieve a purity level above 98%. The decolorization equipment removes pigments and odors from the extract through adsorption technology, simplifying the operation process while improving product quality.
(IV) Concentration and Drying System
The core function of this system is to remove water from the extraction solution, yielding a peptide product that is easy to store and transport. The type of equipment is selected based on product requirements, primarily divided into spray dryers and freeze dryers (lyophilizers). Spray dryers offer high efficiency, with inlet air temperature controlled between 150-200°C. They are suitable for producing peptide products like food additives where moderate activity retention is acceptable. Freeze dryers operate in a vacuum environment at temperatures below -50°C, removing water through sublimation. They achieve peptide activity retention rates exceeding 95% and are predominantly used for producing peptide raw materials in high-end pharmaceutical and cosmetic fields. Some production lines are also equipped with low-temperature vacuum concentrators, which first concentrate the extraction solution to a certain concentration before drying, thereby reducing the loss of active components.
(V) Intelligent Control System
Built upon a PLC control system, this system integrates sensors, data recording, and analysis modules to achieve fully automated regulation of the entire process. It enables real-time monitoring and precise control of key parameters such as enzymatic hydrolysis temperature (35-55°C), pH (pH 7-8 for neutral proteases), reaction time (2-24 hours), and extraction pressure/temperature. This ensures the stability and reproducibility of the production process. Furthermore, the system automatically records all process data, providing a basis for production process optimization. This reduces labor costs while enhancing batch-to-batch consistency.
(VI) Auxiliary Support System
This system includes a fully automatic CIP (Clean-in-Place) system, quality inspection equipment, and solvent recovery equipment. The CIP system enables fully automated operations involving acid washing, alkaline washing, and hot water rinsing, effectively controlling microbial growth and ensuring equipment hygiene and sterility. Quality inspection equipment encompasses material chemical composition analyzers, spectral analyzers, ultrasonic flaw detectors, etc., conducting comprehensive testing on raw materials, intermediate products, and finished products. Solvent recovery equipment is designed to recycle solvents used in processes like membrane separation and chromatography, reducing wastewater discharge and resource waste.
II. Working Principles of the Peptide Extraction Production Line
The core principle of the Jinzong peptide extraction production line involves utilizing physical, chemical, or biotechnological means to disrupt the cellular structure of raw materials, hydrolyze macromolecular proteins into small-molecule peptides, and subsequently obtain high-activity, high-purity peptide products through separation, purification, and drying processes. The overall workflow can be divided into four critical stages, with variations in principle depending on the chosen technological pathway.
(I) Raw Material Pretreatment Stage
This stage employs a combination of mechanical disruption and low-temperature processing to break down the cellular structure of raw materials while preserving peptide activity. Mechanical size reduction decreases particle size, increasing the surface area available for extraction. Ultrasonic homogenization technology utilizes high-frequency vibrations to generate a cavitation effect, further rupturing cell membranes and walls to fully expose peptide molecules. The low-temperature environment (0-4°C) inhibits peptidase activity, preventing degradation of peptide molecules, while simultaneously reducing oxidative damage to peptide structures.
(II) Extraction and Conversion Stage
This stage is central to peptide generation, with enzymatic hydrolysis and supercritical fluid extraction (SFE) being the mainstream technologies. Traditional acid/alkali methods are limited to producing highly stable peptides due to their severe impact on bioactivity. The core principle of enzymatic hydrolysis is to utilize the specific catalytic action of proteases to cleave peptide bonds within protein molecules, thereby hydrolyzing macromolecular proteins into small-molecule peptide fragments. By regulating temperature, pH, and reaction time via the intelligent control system, enzyme activity can be optimized. For instance, a two-step enzymatic hydrolysis process (first with alkaline protease, followed by flavorzyme) can increase peptide yield by over 20%. Supercritical fluid extraction leverages the unique properties of supercritical carbon dioxide, which possesses both gas-like diffusivity and liquid-like solvency. It penetrates the cellular matrix, dissolves target peptide molecules, and allows for selectivity control by adjusting pressure and temperature. This method achieves solvent-free extraction with activity retention rates potentially exceeding 90%.
(III) Separation and Purification Stage
This stage separates peptides from impurities based on differences in molecular size and charge properties. Ultrafiltration membranes screen molecules by pore size, permitting only peptide fragments within the target molecular weight range (hundreds to thousands of Daltons) to pass through, while retaining impurities such as large-molecular-weight proteins and polysaccharides. Ion exchange chromatography separates and purifies different peptide fragments based on charge interactions between the peptide molecules and the chromatographic medium. Decolorization equipment further enhances product purity and sensory quality by adsorbing pigments and odorous substances onto adsorbents.
(IV) Concentration and Drying Stage
This stage converts the peptide extraction liquid into a solid finished product through dehydration while maximizing activity retention. Spray drying rapidly evaporates water using a stream of hot air. Although efficient, it requires careful control of processing time to minimize activity loss. Freeze drying (lyophilization) removes water via sublimation under vacuum and low-temperature conditions, avoiding denaturation of peptide molecules caused by high heat. This significantly improves activity retention rates and is particularly suitable for preparing thermolabile peptide products.
III. Functional Characteristics of the Peptide Extraction Production Line
The Jinzong peptide extraction production line integrates intelligent, green, and customizable technologies, offering multiple advantages including high efficiency, stability, and environmental friendliness, thereby meeting diverse production demands across various sectors.
(I) High Efficiency and Precision with Strong Activity Retention
By precisely regulating process parameters via the intelligent control system and incorporating advanced technologies such as dual-enzyme hydrolysis and supercritical fluid extraction, the extraction efficiency and peptide yield are significantly enhanced. Compared to traditional processes, modern production lines can improve extraction efficiency by over 50%. Simultaneously, technologies including low-temperature processing, short-duration extraction, and freeze-drying maximize the retention of peptide bioactivity. Activity retention rates generally exceed 90%, with some high-end equipment achieving over 95%, fulfilling the demand for highly active raw materials in the pharmaceutical and cosmetics industries.

(IV) Full-Process Quality Control Ensuring High Product Stability
Adhering to international quality management system standards such as ISO, a comprehensive quality control chain is established, spanning from raw material procurement to finished product inspection. The line is equipped with advanced quality testing devices for real-time monitoring of peptide purity, molecular weight distribution, and activity indicators. The intelligent control system automatically records process data, facilitating traceability and optimization to ensure batch-to-batch product stability and compliance with stringent standards in the pharmaceutical and food industries.
(V) Cost Reduction, Efficiency Improvement, and Significant Economic Benefits
Fully automated operations reduce labor costs, while solvent recovery and high-value byproduct development minimize raw material waste. The modular design lowers equipment maintenance costs. For instance, through enzymatic process optimization and solvent recycling, the consumption of enzyme catalysts and chemical reagents can be reduced, significantly cutting production costs. Concurrently, it enhances product added value, empowering enterprises to gain a competitive edge in high-end markets.
IV. Application Fields and Future Trends
Technological iterations in peptide extraction production lines are driving the widespread application of peptide products across multiple fields. In the pharmaceutical sector, they are used to produce high-purity products like antimicrobial peptides and thymosin α1, aiding in disease treatment and immune regulation.
