Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The present invention provides a technical solution: a preparation process for producing nemophore freeze-dried powder, the preparation steps are: S1, material selection and cleaning, select the mature sandworms, and clean the sandworms with water; S2, brake the green, place the selected sandworms on a brake machine for 2-3 minutes, and take them out for use after the brake is completed; S3, dilute alkali treatment, placing the sandworm in a stainless steel bucket, soaking it in 0.5% baking soda solution for 10-20 minutes, then taking it out and putting it in a stainless steel bucket for standby use; S4, grinding, the sandworms are picked out and ground with a colloid mill, the colloid particles are 2 um, and the colloid liquid is spread on a stainless steel plate; S5, pre-freezing and deep freezing, put the tray into the quick freezing workshop, freeze it below -7℃ for 12h, then transfer it to the deep freezing workshop and freeze it below -18℃--30℃ for 24h; S6, vacuum freeze drying, the frozen sandworm powder is sublimated and dried in a freeze dryer, and the drying process is: heating to 80°C under a pressure of 40-100 Pa for 20 minutes, maintaining for 6-8 hours, then reducing the temperature to 45°C, maintaining for 8-10 hours, taking out the sandworm powder block, and obtaining a sandworm freeze-dried powder block with a water content of less than 5%; S7, rolling, rolling the freeze-dried lugworm powder block into granules with a double-roller machine; S8. Packaging: In an environment with a humidity of less than 50%, use aluminum foil to pack the freeze-dried powder of sandworms.

[0018] The sandworms are made into freeze-dried sandworm powder through a vacuum freeze-drying mechanism. The sandworms are collected during the growth and maturity period of the sandworms. The concentration of baking soda in the aqueous solution is 0.5%.

[0019] In step S1, the sandworm is cleaned by placing the sandworm in water and soaking it for 20-30 minutes. After soaking, the sandworm is taken out of the water and continuously rinsed with clean water to rinse away impurities on the outer surface of the sandworm.

[0020] Due to its unique biological characteristics, sandworms are a nutritious food with multiple medical values. Sandworms are a rich source of protein, which is essential for the growth, repair and immune function of the human body. Sandworms contain trace elements such as calcium, magnesium, iron, zinc, selenium, and iodine, which play an important role in maintaining body functions and health. The fatty acids in sandworms, especially unsaturated fatty acids, are beneficial to heart health. Sandworms also contain a certain amount of vitamins, such as vitamin E, which has antioxidant effects. The fat content of sandworms is relatively low, which makes them a choice for a healthy diet. Sandworms are a low-cholesterol food source and a good choice for people who need to control blood lipids. The meat of sandworms is delicate and easy to digest and absorb, making them suitable for people of all ages. Due to their high protein content, sandworms can also be used as energy-providing food.

[0021] In step S2, the parameters of the brake machine are pre-adjusted to carry out the brake work. After the brake work is completed, the staff will take the sandworms out of the brake machine and place them in a clean container for use.

[0022] The present application can effectively kill bacteria, parasites and harmful microorganisms present in the sandworms by performing a green treatment on the sandworms, thereby ensuring the hygiene of the sandworms, stabilizing the internal structure of the sandworms, reducing water loss and oxidation reactions, and extending the shelf life.

[0023] In step S3, ensure that there is no oil stain in the stainless steel barrel and the stainless steel barrel is corrosion-resistant. Pour clean water into the stainless steel barrel. After pouring the water, slowly pour baking soda powder into the clean water. During the pouring process, constantly stir the clean water in the barrel until the baking soda is dissolved in the water to form a 0.5% baking soda solution. During the soaking process, the baking soda solution penetrates into the surface of the sandworm. After the soaking is completed, use a strainer to carefully fish out the sandworm and place it in a stainless steel barrel for later use.

[0024] The present application continuously stirs baking soda to dissolve the baking soda in water, thereby ensuring uniform concentration of the solution, so that the baking soda penetrates into the outer surface of the lugworm, decontaminates the lugworm, and ensures the taste of the lugworm.

[0025] In step S4, the sandworms are fed into the feed port of a colloid mill for grinding to refine the sandworms into colloidal particles. After grinding, the sandworm colloidal particles are evenly placed on a stainless steel plate for spreading.

[0026] This application is processed by grinding, which can effectively refine the particles, improve the quality and enhance the stability of the product.

[0027] In step S5, the sandworm powder is placed in a quick-freezing workshop, the door is closed, the freezing program is started, and the appropriate pre-freezing temperature and time are set. After the quick-freezing time is reached, it is transferred to a deep-freezing workshop for freezing to ensure that the sandworm powder is completely frozen into solid ice crystals.

[0028] In step S7, the gap between the rollers of the roller machine is adjusted and the rotation speed is set. After the rolling is completed, the nemosilver freeze-dried powder is collected through a collection bucket.

[0029] In step S8, the packaging is performed by weighing the nemosilver freeze-dried powder by weight using a metering device, filling the weighed nemosilver freeze-dried powder into an aluminum foil bag, and then putting the bag into a sealing machine for sealing.

[0030] Inspect the appearance of the sealed package to ensure there is no damage. Example 1
