Product description of collagen peptide refining and extraction production line: The extraction technology of collagen mainly includes hydrolysis collagen method, enzymatic hydrolysis method, etc. Currently, enzymatic hydrolysis method is popular, and its process is as follows (taking the production of fish scales as an example)

Application of collagen peptides:

Collagen peptides have diverse biological activities, mainly derived from underutilized natural resources, and are considered a safer choice for developing health products.

Collagen peptides have a wide range of applications and market prospects in cosmetics, food, medicine, and other fields;

In biomedicine, collagen peptides have the advantages of low allergenicity, excellent cell tolerance, and affinity, making them suitable for drug stability, drug carrier, and preparation of medical dressings.

In terms of beauty, collagen peptides are commonly used in skincare cosmetics due to their mild properties and high safety, playing a role in moisturizing, reducing wrinkles, alleviating ultraviolet radiation, and delaying skin aging;

The food industry is the most widely used field for collagen peptides, which can be added to food as ordinary food raw materials or functional ingredients to supplement protein nutrition and promote the health of skin, hair, bones, joints and other parts;

Collagen peptide production line

Collagen process flow: raw material thawing → cleaning → crushing → enzymolysis → filtration → decolorization → concentration → spray drying → finished product

Collagen is an extracellular protein and the most abundant protein in the human body, accounting for over 30% of the total protein in the body. Collagen is rich in amino acids such as glycine, proline, and hydroxyproline that the human body needs. Collagen is the most important component of the extracellular matrix, and the effects of collagen from different sources vary greatly. Ordinary collagen is extracted from pig, cow skin bones, and ordinary fish skin, while top-grade collagen is extracted from deep-sea fish skin without any pollution. The “collagen” with a molecular weight of 1000-2000 daltons has the strongest activity, the best absorption effect, the most stable powder form, and does not require the addition of any preservatives, ensuring good safety

The necessary production steps and processes for the enzymatic hydrolysis production line of fish scale collagen are as follows:

The production process includes: cleaning, cooking, enzymolysis, decolorization, filtration, concentration, spray drying, packaging and other important production links, and describes the equipment used in each process separately.

1. Cleaning: If the raw materials used in this process are directly purchased from the raw material supplier to remove ash from fish scales, construction is not considered. However, if fresh wet fish scales are purchased for self ash and degreasing treatment, a floor cleaning tank needs to be constructed. The cleaning tank should be designed with one for acid and alkali degreasing and ash removal treatment. There is no special equipment for this process, only the civil engineering needs to be done. The water used in the cleaning process should be deionized water, and it needs to be matched with two-stage reverse osmosis purified water (public).
2. Enzymatic hydrolysis: The fish scales treated with defatting and ash removal are put into an enzymatic hydrolysis reaction tank for thermal insulation enzymatic hydrolysis. The equipment and supporting facilities used include double-layer insulation and pressure resistant enzymatic hydrolysis tanks, operating platforms, and fuel steam boilers. (Note: The production equipment that comes into direct contact with the material is made of 304 or higher stainless steel. Sanitary hoses and stainless steel pipes are used during the transportation of the material.)
3. Filtration: This process uses a vertical diatomaceous earth filter to finely filter the enzymatic hydrolysate to meet the requirements of the next process.

The equipment and supporting facilities used include two sets of single-layer pressure resistant liquid storage tanks, a vertical diatomaceous earth filter machine, and a workshop 100000 level air conditioning purification equipment (public).

4. Concentration and spray drying: the filtered liquid can be dried by spray only after reaching a certain concentration before entering the spray tower, which is of great significance for improving economic benefits and production efficiency. The equipment and supporting facilities used in this process include single-layer pressure resistant liquid storage tank, single effect falling film concentration and centrifugal spray drying tower.
5. Filling: If the product needs to be in liquid form, the filtered liquid can be directly packaged into standard small buckets. After passing the inspection, it shall be stored in the warehouse. A single-layer pressure resistant liquid storage tank and packaging drum drying sterilization room are required.
