Abstract

PURPOSE:To obtain a feed with high production efficiency, by adding mineral water and high-temperature enzymes to a crushed raw material so that it is digested, followed by fermenting and aging it. CONSTITUTION:Waste obtained from processing of aquatic products or the whole fish bodies as a raw material are ground by the crush er 1, thrown to the dissolving tank 2, stirred and allowed to stand. In stirring, mineral water and a very small amount of a vegetable high-temperature enzyme are added to the tank at 66-73 deg.C for 8hr, and the raw material is sterilized and made into a solution. In taking out the solubilized raw material and packing it into the aging chamber 3, a very small amount of middle-temperature reproducible bacterium such as a mold belonging to the genus Bacillus and various kinds of hydrolases such as protease, cellulase, etc. are added to the raw material, which is aged and fermented at 43-45 deg.C at the humidity of 35% for 3-5 days. Air is sent in the tank 3 and the raw material is partially dehydrated, to give the raw material in the form of a concentrated solution. It is put in the drum dryer 4 and dried to give a powdery feed.

Description

[Detailed description of the invention] The present invention relates to a method for producing aquatic feed.

Conventionally, the method for producing this kind of aquatic feed is to put fish raw materials in a steamer, stir vigorously in a high-temperature atmosphere, steam the fish itself in the moisture in the matrix, achieve thermal decomposition and physical decomposition, and produce bone fragments etc. Remove all undissolved portions of the substrate through a decanter filter.
After pressing to squeeze out water and 411 minutes, the solid portion remaining during pressing was returned to the high-pressure steamer and made airtight.
A manufacturing method of vacuum drying, or adding normally cultured fermentation bacteria to crushed fish raw material to decompose and ferment the raw material substrate, and add additives such as rice bran, bran, and fiber for the purpose of moisture content adjustment and water absorption. There is a method of producing feed by mixing, adjusting the 0/N ratio at the same time, and performing aerobic fermentation.

However, in the former method, the raw materials are heated at temperatures above 100℃.
High i'i+? Since it is heated under pressure, fossil fuel consumption is large, and the crystallized water in the substrate is separated and dehydrated, useful minerals are scattered, and proteins are denatured, making it strong but lacking in nutritional value. Moreover, the water treatment system discharges the wastewater containing SS (→J-spending subject) in the raw material when fish oil is separated and removed, rather than the feed that is prone to rancidity due to the residual non-lid fat content. There are disadvantages such as the need for such work. In addition, in the latter method, fuel consumption, water treatment work, and the nutritional value layer 1 are eliminated, but since additives such as fibers are added to the fish raw material at a rate of 100% or more, the resulting product is Although the amount of protein increases, the ratio of protein content decreases and the quality is not constant.In the case of heat treatment, there are various disadvantages such as the need to secure and stockpile the additives.

For this reason, there has been a long-standing demand in the industry for a feed manufacturing method that is low in fuel consumption, requires few input additives, has a simple manufacturing process, and has high manufacturing efficiency, but currently no such method exists.

In the present invention, mineral water and high-temperature enzymes are added to the pulverized raw material to digest the substrate, and then fermentation bacteria and enzymes are added to the raw material to make it ripen, and at the same time, glycerin, etc. By rapidly drying a concentrated solution of bacterial cell proteins and a large number of living creatures,
The present invention provides a new method for producing aquatic feed that achieves the simple rationalization of the production process and the improvements in production efficiency.

The present invention will be specifically described below with reference to the apparatus shown in the drawings.

The present invention uses water 1f (fish head, viscera, etc. discarded parts obtained during e-processing) and whole fish bodies as raw materials, chews them (1) and crushes them to +'ili, Next, the pulverized raw material is put into a melting vessel 2), stirred, and left to stand. When stirring 1゛1', add multi-element coexisting mineral water and a trace amount of vegetable high 7! Salmonella bacteria that adhere to the raw material by putting the iA flI element into a tank maintained at 66°C to 73°C for about 8 hours,
In addition to sterilizing pathogenic bacteria such as staphylococcus, the raw material )k
'eI is digested and decomposed and the pulverized raw material is made into a solution.

Here, multi-element coexisting mineral water performs a catalytic action at the quantum chemical level in biochemical reactions, and at the same time captures the deodorizing action as a co-catalyst and active atom prisoner5).
It contributes to the total activation of 1t11 of the bacteria introduced in the next third step. Furthermore, when taking out this solutionized raw material and loading it into the curing chamber (3), 7+17L of micro 111 D:
For example, aerobic bacteria and anaerobic bacteria such as Bacillus are added, and a small amount of each hydrolyzing element such as protease, cellulase, amylase, and lipase is added to the tank. Internal temperature 43°C to 45°C1 Humidity 35
Cured for 3 to 50 minutes under 96°C and fermented. At this time, 4
1"f f31 contains 3 rre for 10 Kl of raw material
/min, and the raw material is gradually partially dehydrated by the blowing action and microbial activity to form a concentrated solution raw material. Here, the bacteria and enzyme group are saturated fatty acids, alcohol,
Alternatively, glycerin can be carried into the metabolic pathway of microorganisms and incorporated as part of the bacterial cell tissue, forming bacterial cell proteins as a whole. It is preferable to use pure water-cultured bacteria as the various bacteria, and to mix the aerobic bacteria and anaerobic bacteria at a ratio of 2:2. The concentrated solution raw material thus obtained is taken out of the curing chamber (3) and placed in a drum dryer (4) to be dried and made into powdered feed.

Example 1000 kg of fish body raw material was crushed in a crusher.
After k L/, put it in a dissolution tank and add multi-element coexistence mineral water 5
501° High temperature enzyme 1501 was added and the temperature was raised to 66°C to 73°C.
The mixture was stirred and left at ℃ for 8 hours. Next, 500 billion solid microorganisms and 500 billion hydrolyzed rl ions were added to this solution raw material.
The oo unit was put in the curing room (3). At this time, the growth rate of the microorganisms was between 22 and 45 minutes.

The weight of the concentrated solution raw material cured in this way for 5 days was 1050
The water content was about 70% in Kr. Next, when the concentrated solution raw material was dried with a drum dryer (4), 29
A powdered feed containing 0 garlic was obtained.

The ingredients of the feed thus obtained are as follows.

In the present invention, as described below, the steps from raw material extraction in the first step to raw material drying in the fourth step are performed continuously under normal pressure, so the manufacturing process is simple and the work safety is improved. Effective in improving efficiency.

Therefore, unlike conventional methods, fuel consumption is reduced because high-temperature and pressure heating is not performed. - Highly nutritious feed rich in digestible pure protein can be obtained instead of deception. Various equipment and water treatment work required when distributing fish oil. is not 1υ.

Furthermore, since large ffF additives such as fibers are not required for the raw material, it is effective in mass processing, and has the effect of achieving the purpose of the invention.
