The use of potatoes to make crab feed has a wide range of raw materials, low cost, good palatability, nutrient-rich, crab-like food, and can be used for feeding fish, shrimp and other aquatic products. At the same time, the feed production method is relatively simple, both mechanically and mechanically, and can be hand-made, so the potato crab feed has a wide range of application values. The technical points of its processing and feeding are introduced as follows. 1. Process selection → cleaning → cutting → cooking → crushing → batching → forming → drying. 2, processing technology (1) Selection of materials. Select pest-free, germ-free, mold-free potatoes as raw materials. Use more nutritious spring potatoes. (2) Cleaning. Remove the potato skins mechanically or manually and wash the peeled potatoes with water. (3) Whole cut. Make the potatoes the same size through proper cutting so that the cooking consistency is consistent. (4) cooking. When the potatoes are cooked until they mature in a stainless steel or aluminum pan or steamer, the ceasefire cools. (5) broken. Immediately after cooling, the potatoes are picked up and broken into paste or thick paste by mechanical crushing or manual stirring. (6) ingredients. In order to increase palatability and increase nutrient content, the above ingredients can be added in a ratio of 100 grams of salt, 50 grams of flavor, 100 grams of ferulic, and 2 kilograms of vitamin c per 100 kilograms of potatoes in the shredded potatoes, and the mixture is stirred in time. (7) molding. Make small cubes or granules of suitable size mechanically or manually. (8) Drying. After drying or drying in time, seal and store in plastic bags. 3. Feeding Methods Adult crabs are fed 2 to 3 times a day. Juveniles are fed 1 to 2 times a day, but they must be fed again after the last feeding. The bait should be placed in a clean place. It is best to set the feeding station to feed. Feeding fish, shrimp, etc. can be performed with reference to conventional methods. Rushan Jinguo Food Co., Ltd , https://www.jinguofood.cn
