[0053] Embodiment 2

[0054] This embodiment discloses a method for preparing shrimp powder, which comprises the following steps:

[0055] Step 1: adding the raw shrimp to be dried into the preparation equipment for drying and grinding;

[0056] Step 2: pre-treat the ground raw materials with microwaves at a microwave power of 4500-5000 W, a microwave time of 5-10 min, and a solid-liquid ratio of 1:3-4;

[0057] Step 3, adding protease to the raw material after microwave pretreatment, so that the shrimp meat solution has a solubility of 20-30% and performs enzymolysis at a temperature of 50-55° C. for 5-6 hours;

[0058] Step 4: spray-dry the enzymatically hydrolyzed raw materials, with a liquid temperature of 45-50°C, an air inlet temperature of 150-170°C, and an air outlet temperature of 80-95°C.

[0059] The specific working method is: when in use, first open the sealing door 5. During the sliding process of the sealing door 5, the driving rack 613 drives the driving gear 604 to rotate, and then drives the rotation of the rotating rod 2 603.

After the discharge is completed, the dried shrimp shells can be put into the grinding cylinder 403, and then the cleaned shrimp shells are put into the placement plate 201, and the sealing door 5 is closed. The above steps are carried out in reverse. Through the connection between the right-angle driving rod 410 and the circular plate 401, when the sealing door 5 is closed, the reciprocating rack 311 and the follower rack 608 are driven to slide toward the inside of the drying box 1 at the same time, thereby driving the grinding assembly 4 to reset and the rollers 203 to rotate, and the shrimp shells accumulated on one side of the placement plate 201 during feeding are spread out to make them evenly distributed;

[0060] After feeding, the drying operation is carried out. The driving gear 15 can be driven by the motor 16 to rotate. The driving gear 15 drives the driven gear 14 to rotate. The driven gear 14 can drive the rotating gear 301 meshing therewith to rotate. The rotating gear 301 drives the swing rod 303 to rotate on the fixed shaft 302. The rotation of the swing rod 303 can drive the reciprocating right-angle rod 305 rotatably connected thereto to slide horizontally back and forth inside the limit sleeve 304. The movement of the reciprocating right-angle rod 305 can drive the reciprocating movement of the piston 309. At this time, the electric valve 308 on the air cylinder 307 is in an open state. In the state, the reciprocating motion of the piston 309 can drive the reciprocating motion of the connecting rod 310 and the reciprocating rack 311, and then drive the reciprocating rotation of the roller 203. Through the heating of the electric heating wire 204 arranged at the bottom of the placement plate 201, the rotating roller 203 can be heated evenly and the shrimp shells can be dried evenly. When the reciprocating right-angle rod 305 drives the reciprocating rack 311 to dry, it drives the reciprocating motion of the grinding rack 408, and then drives the reciprocating gear 312 meshing therewith to reciprocate, so that the grinding protrusion 406 inside the grinding cylinder 403 can be rotated to grind the dried shrimp shells put in;

[0061] During the drying process, the wet shrimp shells will produce water vapor. The fan 8 can be used to extract the internal humid air, and the wind wheel 13 can be driven through the cooperation between the air outlet pipe 9 and the branch pipe 10, thereby reducing the energy consumption of the fan 8. The drying box 11 connected through the branch pipe 10 can dry the moist hot air, and then it flows back to the inner cavity of the placement plate 201 through the air outlet hose 12 and is blown out through the air outlet hole 202, so that the upper part of the shrimp shell can be blown to improve the drying effect.
