Fish powder production process

Abstract

The invention discloses a fish powder production process, which comprises: 1, feeding fresh fish into a mincing machine, and cutting into fish blocks; 2, feeding the fish blocks into a presser, carrying out pressing dewatering, and extruding to obtain flaky fish meat cake, wherein the water content in the flaky fish meat cake is reduced to below 45%; 3, feeding the flaky fish meat cake into a baking line, and heating the flaky fish meat cake to prepare a dried cake, wherein the water content in the dried cake is reduced to 1-5%; 4, removing the dried cake from the baking line, and cooling to a room temperature; and 5, carrying out breaking grinding on the dried cake to obtain the fish powder. According to the present invention, the original processing method using a lot of steam is changed, such that the energy is saved, the quality of the fish powder is improved, the process is simplified, and the energy consumption due to the secondary heating on the fish water is avoided.

Description

technical field [0001] The invention relates to the technical field of preparation or processing of food or food material, in particular to a fishmeal production process. Background technique [0002] At present, the main process of fishmeal production is: whole fish cooking → dehydration of meat → drying of fish meat → distillation of fish water. The quality of the fishmeal produced during the production period is also more, which leads to a large investment of the enterprise and increases the production burden of the enterprise. Contents of the invention [0003] The invention provides a fishmeal production process, which changes the original processing method of using a large amount of steam, not only saves energy, but also improves the quality of fishmeal, simplifies the process, and avoids the energy consumption of secondary heating of fish water. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invent...

Problems solved by technology

[0002] At present, the main process of fishmeal production is: whole fish cooking → dehydration of meat → drying of fish meat → distillation of fish water. The above-mentioned production process requires a large amount of steam, and also requires secondary heating energy consumption, which not only consumes a lot of heat energy, but also reduces production. The quality of the fishmeal produced during the period is also more involved, resulting in a large investment for the enterprise and increasing the production burden of the enterprise
