This invention relates to the field of feed technology and provides a compound feed and preparation method for enhancing the redness of cooked river crab shells and crab roe. The feed comprises the following raw materials by weight percentage: fish meal 25-32%, defatted soybean 8-12%, blood meal 3-5%, cottonseed meal 3-5%, cottonseed meal enzymatically hydrolyzed protein 0.8-1.6%, peanut meal 16-20%, rapeseed meal 1.5-2.5%, α-starch 18-22%, soybean lecithin oil 2.5-4.0%, fish oil 1-2%, calcium dihydrogen phosphate 1.2%-1.5%, zeolite powder 0.6-1.0%, compound premix 1%, capsanthin 0.5-1.0%, zeaxanthin 0.3-0.5%, natural astaxanthin 0.1-0.2%, bile acids 0.5%, and ethoxyquinoline 0.5%. This invention utilizes the strong emulsifying properties of phospholipids to improve the bioavailability of carotenoids and enhance the redness of the hepatopancreas and crab shell; it also utilizes the phospholipid components rich in soybean phospholipid oil to promote the development of crab gonads, increase the volume of crab roe (hepatopancreas and gonads), and further enhance the overall visual redness of the crab roe through pigment accumulation during gonad development.

This invention relates to the field of blood meal processing equipment technology, specifically disclosing a drying and grinding device for blood meal processing, including a base, a drum-type processing chamber, a left support bushing, a right support bushing, a screw conveyor, a feed drive motor, a rotating main shaft, a rotating drive motor, multiple scraper blades, multiple grinding roller assemblies, a cylinder rotation drive mechanism, and an inclination adjustment mechanism. The scraper blades and grinding roller assemblies are both mounted on the rotating main shaft, and the grinding rollers form a grinding gap with the inner wall of the processing chamber. The cylinder rotation drive mechanism drives the processing chamber to rotate independently. The inclination adjustment mechanism consists of a support seat and a lifting device, used to adjust the inclination angle of the processing chamber. This invention achieves dynamic drying and flexible grinding through the combined motion of the processing chamber rotation and the main shaft rotation. The scraper blades continuously clean the inner wall to prevent sticking and coking, and the inclination adjustment allows for online control of material residence time, significantly improving processing uniformity, product quality, and thorough discharge.
