Patent CN101926409A "A Feed Additive Using Shrimp Head and Plant Feed Protein Mixed Fermentation and Its Processing Method" discloses the process of using shrimp head as feed processing, but the fermentation process is closed fermentation, which requires regular ventilation, material turning and other steps , the processing process is relatively cumbersome, and when the shrimp head pulping process is complicated, a large amount of water needs to be added, which is not conducive to industrial production, and also increases the production cost of the finished product virtually.
[0004] Ordinary shrimp head processing technology usually adopts one-time fermentation to produce feed, so the content of small peptides and organic acids in the feed is not very high, the storage time of the finished feed is relatively short, and the moisture content of the material in the one-time fermentation production method is relatively high , which is not conducive to the subsequent drying process

Embodiment 1

[0025] Craft such as figure 1 As shown, 1 ton of fresh shrimp heads are squeezed and separated to obtain shrimp shells and semi-liquid shrimp paste. The shrimp paste is 496-633 kg, and the shrimp shells are directly dried to make chitin and other raw materials; the obtained shrimp Heat the slurry to 92°C and keep it for 15 minutes to complete the sterilization and passivation of the shrimp slurry, which can ensure that the shrimp slurry does not deteriorate within a certain period of time, and basically removes the activity of some enzymes contained in the shrimp slurry itself, ensuring the cost of feed. Stability: add 500kg of sterilized and passivated shrimp paste to 500kg of soybean meal, add 1.2kg of solid compound fermentation bacteria to inoculate and mix (10%-40% for lactic acid bacteria, 10%-40% for yeast, 10% for bacillus %-40%, Aspergillus niger is 5%-10%, the strain content is 2×10 11 -8×10 11 cfu / g), and add 3kg of starch, 3kg of molasses, and 1.2kg of peptone an...

Embodiment 2

[0029] Craft such as figure 1 As shown, 1 ton of fresh shrimp head is squeezed and separated to obtain shrimp shells and semi-liquid shrimp paste. The shrimp paste is 496-633 kg. The extruded shrimp shells are directly dried to make chitin and other raw materials; Heat the obtained shrimp paste to 93°C and maintain it for 20 minutes to complete the sterilized inactivation of the shrimp paste; add 600kg of the sterilized inactivated shrimp paste to 500kg of soybean meal, and add solid composite fermentation bacteria to inoculate and mix 1.8kg (of which lactic acid bacteria 10%-40%, 10%-40% for yeast, 10%-40% for Bacillus, 5%-10% for Aspergillus niger, the strain content is 4×10 11 -9×10 11 cfu / g), and add 4kg of starch, 4kg of molasses, and 1.8kg of peptone and mix thoroughly (after mixing, the water content of the material is 49.8%), put the mixed material into an open fermentation frame and place it in an open environment Carry out fermentation (the fermentation temperature...

Abstract

The invention belongs to the field of fodder processing, particularly relates to a method for preparing fermented fodder with shrimp heads. The method comprises the following steps that the shrimp heads are extruded and separated into shrimp shells and shrimp paste; then the obtained shrimp paste is sterilized and the enzyme is inactivated, and the shrimp paste is mixed with the fodder; meanwhile, compound fermentation bacteria and accessories are added in; fermentation is carried out through an open fermentation method; after fermentation, the materials are dried and discharged; the first fermented materials are mixed with the sterilized and enzyme-inactivated shrimp paste twice; meanwhile, the compound fermentation bacteria and the accessories are added in; secondary fermentation is carried out through the open fermentation method; after the fermentation, the materials are dried and discharged; and finally the materials are crushed and packaged into a finished product. According to the method for preparing fermented fodder with shrimp heads, the material turning and the ventilation do not need to be carried out regularly, so that fermentation procedures are simplified and labor forces are saved; in addition, the content of such nutrient substances as organic acid, protein, and small peptide in the fodder is higher than that in one-time fermented fodder, the product uniformity is correspondingly improved, so that the used amount of fermentation carriers is reduced, and the production cost is also reduced.

Description

technical field [0001] The invention belongs to the field of feed processing, and in particular relates to a method for producing fermented feed by using shrimp heads. Background technique [0002] People are in the processing process of shrimp, and shrimp head is often treated as processing waste, and the weight of shrimp head accounts for 30%-40% of shrimp body weight, so the annual shrimp head that my country mainland rejects is about 70,000 tons. However, shrimp heads are rich in protein, unsaturated fatty acids, calcium, magnesium, phosphorus mineral salts and other nutrients, among which the protein content reaches 20%-40%. However, due to the immaturity of the shrimp head processing technology and the influence of the hot summer climate, a large number of shrimp heads will rot, deteriorate and be wasted in vain, and will pollute the surrounding environment and bring troubles to the surrounding residents. [0003] Shrimp heads are usually used in the process of feed p...
