Constant Temperature Enzymolysis Tank for Aquatic Feed

Product Overview:

An enzymatic hydrolysis system equipped with precise automatic controls for temperature (±0.5°C) and pH, designed specifically for the controlled enzymatic hydrolysis of by-products such as fish paste and fish processing water. It upgrades low-value fish and shrimp—or processing trimmings—into high-value small-molecule protein peptides and flavor precursors, making it widely applicable in the production of bioactive materials such as aquatic feed-attracting peptides and fish sauce powder.

Key Advantages and Selling Points:

Precise Temperature and pH Control: Achieves temperature control accuracy of ±0.5°C and stable, automated pH regulation; creates an optimal environment for enzymatic hydrolysis to maximize enzyme activity and ensure excellent batch-to-batch consistency.

Efficient Low-Temperature Enzymatic Hydrolysis: Hydrolysis proceeds under mild conditions, maximizing the retention of small-molecule peptide activity and natural flavor compounds while preventing nutrient loss and flavor degradation caused by high temperatures.

Significantly Enhanced Degree of Hydrolysis: Targeted enzymatic processes increase the degree of protein hydrolysis by 20%–30%, generating abundant functional small peptides and free amino acids, thereby markedly improving palatability and digestibility.

Broad Substrate Compatibility: Capable of processing various wet by-products—such as fish paste, fish processing wastewater, shrimp heads, and shellfish processing waste—and flexibly adapting to low-value raw materials from diverse sources, effectively turning waste into value.

High Level of Automation: Features integrated automatic control for multiple parameters (temperature, pH, agitation, and processing time); enables one-touch operation with minimal manual intervention, ensuring stable and reliable performance.

Primary Applications:

High-value utilization of low-value fish/shrimp and processing by-products

Enzymatic production of aquatic-derived feeding-attractant small peptides and fish sauce flavor compounds

Pre-processing and production of bioactive materials such as protein peptides and yeast extracts for animal feed

Specific problems addressed:

Low utilization of low-value raw materials → Enzymatic hydrolysis converts them into high-value small-molecule peptides and flavor compounds.

Insufficient degree of hydrolysis affecting palatability → Increases the degree of hydrolysis by 20%–30%, releasing more flavor-enhancing peptides and amino acids.

Significant fluctuations in temperature and pH → Automated, precise control ensures stable hydrolysis conditions and consistent batch quality.

Susceptibility to flavor and nutrient loss → Mild processing conditions preserve natural flavors and bioactivity.

Complex manual operations → Fully automated control simplifies production management and reduces labor costs.

Benefits for users:

Turning waste into value: Converts fish and shrimp processing by-products into high-value feeding-attractant peptides and fish sauce powder, significantly boosting the added value of raw materials.

Product differentiation: Feed ingredients rich in functional small peptides offer unique feeding-attractant properties and growth-promoting effects, enhancing market competitiveness.

Stable and controllable quality: Precise control ensures consistent composition across batches of enzymatic hydrolysates, providing a reliable raw material source for formulations.

Green and sustainable development: Resource utilization of processing by-products reduces waste emissions, aligning with circular economy principles.

Significant cost advantages: Enzymatic hydrolysis exponentially increases the value of low-cost raw materials, improving the enterprise's overall economic performance.
