Abstract
The invention discloses a production process for a soft feed suitable for the growing period of crustaceans. The production process is characterized in that raw materials of the soft feed contain one or more of soyabean protein powder, egg yolk powder and corn protein powder, and an additive contains biologic small peptides. The production process comprises the steps of primary mixing, secondary mixing, curing and pelletizing and obtaining finished products. In the step of curing and pelletizing, the secondary mixing materials are fully refined and cured by using steam, then subjected to a film-squeezing and roller-pressing extrusion process with a pelletizer and are pelletized and molded into granulated feeds through die holes, wherein the pelletizing temperature for the granulated feeds is 95 to 100 DEG C; and then the granulated feeds are fed into a cooking bin for temperature preservation. The soft feed manufactured by the production process is suitable for the requirements of the growing period of the crustaceans, meets the behavior and nutrition requirements of raised animals and has the advantages of good stability in water, high utilization rate, no pollution to water environment, rational production process and design, strong implementation, low production cost and suitability for large-scale industrial production.
