[0002] At present, gelatin with added DHA is a material with special nutritional value. DHA, or docosahexaenoic acid, is a polyunsaturated fatty acid that is very important to the human body. It plays a key role in the development of the brain and retina, and helps to improve intelligence, vision, and memory. Gelatin with added DHA can provide this important nutrient to the human body. Gelatin is a protein obtained by hydrolyzing collagen in connective tissues such as animal skin, bones, and tendons. It has good solubility, gelling properties, and film-forming properties. It is widely used in food, medicine, cosmetics and other fields. Gelatin with added DHA can combine the characteristics of gelatin and the nutritional benefits of DHA to develop more products with high added value. During the stirring process of the colloidal material, due to the low fluidity of the material, the presence of air between the materials, and the existence of cavities in the materials, the materials cannot fully contact each other, affecting the mixing uniformity.

At the same time, when the material passes through the gap between the auger plates and reaches the position of the pressing column, the gap between the auger plates is blocked by the pressing column, resulting in a reduction in the gap, so that the materials are fully squeezed during the transmission process, so that the air between the materials is squeezed out, and the air between the materials is fully contacted after being squeezed out, thereby improving the relaxation effect and avoiding a large amount of space between the colloidal materials. The air prevents the materials from fully contacting each other, which reduces the stirring and mixing effect. A material pressing column is installed between the outer cylinder and the inner cylinder. The end of the material pressing column close to the inner cylinder is fixedly connected to the outer side of the inner cylinder, and the material pressing column is evenly installed along the outer side of the inner cylinder.

The rotation of the arc stirring block drives the material at the bottom of the stirring tank to rotate and pressurize, so that the bottom material is fully mixed. At the same time, during the rotation process, the bottom material is driven to move upward a certain distance by extrusion, close to the auger plate, so that the bottom material is more easily driven upward for extrusion, thereby improving the mixing effect and improving the uniformity of the material.

[0009] The present invention provides gelatin with added DHA and a preparation method and equipment thereof. It has the following beneficial effects: 1. The gelatin with added DHA and its preparation method and equipment cooperate with the auger plate and the pressing column. The rotating auger plate drives the bottom material to surge upward, so that the bottom material and the upper material exchange positions, so that the materials are fully contacted and mixed. At the same time, when the material passes through the gap between the auger plates and reaches the position of the pressing column, the gap between the auger plates is blocked by the pressing column, causing the gap to be reduced, so that the materials are fully squeezed during the transmission process, so that the air between the materials is squeezed out, and the materials are fully contacted after the air is squeezed out, thereby improving the relaxation effect and avoiding the presence of a large amount of air between the colloidal materials, which causes the materials to be unable to fully contact with each other, resulting in reduced stirring and mixing effects.

[0011] 3. The gelatin with added DHA and its preparation method and equipment use a material blocking disk to block the material. During the process of introducing and stirring the material, the material blocking disk cooperates with the support ring to prevent the material from contacting the connection position between the shaft block and the motor, preventing the material from overflowing from the mixing tank through the gap between the shaft block and the motor connecting shaft, and at the same time preventing dust from being introduced into the gap to affect the quality of the gelatin.

[0012] 4. The gelatin with added DHA and its preparation method and equipment drive the material at the bottom of the stirring tank to rotate and pressurize through the rotation of the arc stirring block, so that the bottom material is fully mixed. At the same time, during the rotation process, the bottom material is driven to move upward a certain distance through extrusion, close to the auger plate, so that the bottom material is more easily driven to surge and extrude upward, thereby improving the mixing effect and improving the uniformity of the material.

[0013] 5. The gelatin with added DHA and its preparation method and equipment cooperate with the scraper bar through the side plate to guide the material scraped by the scraper bar, so that the scraped material is driven by the rotating side plate, and the material is squeezed and moved inward, close to the stirring mechanism and the pressing mechanism, to avoid the outer material not being fully driven, resulting in insufficient contact between the inner and outer layer materials.
