Flake abalone compound feed and production method thereof

Abstract

The invention relates to a flake abalone compound feed and a production method thereof. The feed comprises the following steps of: brown fishmeal, expanded soybean meal, kelp powder, laver powder, beer yeast, vital gluten, emulsified oil, an abalone premix, white granulated sugar, eggs, flour, and water. The production method concretely comprises the production steps of: processing materials, dosing, agitating at the first time, agitating at the secondary time, tabletting, curing, drying and cooling. The flake abalone compound feed provided by the invention is dark green in appearance, mellow in algae fragrance and excellent in stabilizing property; the disintegration time can be up to 96 hours in a common water body, and can be up to 72 hours in a high-wave water body; the factory high-temperature drying is removed in the production technology; the slow drying with the low temperature being less than or equal to 80 DEG C is adopted; and the damage of high temperature to nutritional ingredients is avoided. The nutritional requirement and the digestive capability of the abalone are fully considered from two aspects of formula and process; and the raised abalone is bright in shell color, and is deeply trusted by farmers.

Description

technical field [0001] The invention belongs to the field of special aquatic feed, and in particular relates to a compound feed for flaky abalone and a production method thereof. Background technique [0002] Abalone, a special aquatic product, whether its meat is used as a seafood treasure for nourishing yin and strengthening the kidney, or its shell is used as a traditional medicinal material for improving eyesight and clearing the liver, has played and will play a rare role in the history of human economy for a long time. There are rich and diverse varieties of abalone from north to south in my country. In the 1970s, artificial breeding of abalone was successful, and in the 1980s, a certain scale was formed. However, the abalone breeding cycle is long, and most of the larvae need two and a half to three years of growth to mature. Fully meet the nutritional needs of abalone. At present, there are two forms of abalone compound feed on the market in my country, one is powd...

AI Technical Summary

Problems solved by technology

[0003] It is undeniable that these abalone feed products have made a certain contribution to the scale and industrialization of abalone. However, market research also shows that the feeding effect of the existing commercial abalone feed still needs to be improved

First of all, in terms of meeting the nutritional needs of abalone, the commercially available abalone feed generally blindly pursues protein content, which not only discourages seedling growth, but also is not conducive to the management of aquaculture water. The fullness is closely related to the calcification speed of its shells, and the two should be balanced

Therefore, on the one hand, it needs to be further optimized in terms of the composition of feed raw materials; satisfactory

Secondly, the existing feed for abalone has obvious deficiencies in attracting food and stability in water

Again, in terms of the production process itself, the existing process mostly uses the puffing principle to temper the raw materials. Although it is simple and easy to implement, it is not ideal in terms of product sensory indicators. As disclosed in "Abalone Compound Feed and Its Manufacturing Method" Although there is no mention of the puffing process in the production technology, the technological process is too complicated, and the result is not easy to control. There is still a long way to go before the entire industrial chain is truly mature.

In addition, in the drying step, the traditional process generally uses a drum dryer, and the drying temperature is above 100°C, which has the advantage of high efficiency, but often destroys the nutritional content of abalone feed due to excessive temperature
