Problems solved by technology

It should also be pointed out that my country has a large number of seaweed glue processing enterprises. In the process of using seaweed to process and extract seaweed glue, this industry will produce a large amount of waste-kelp slag, which is mainly composed of incompletely digested kelp pieces, Composed of kelp fiber, sugar gum, sodium alginate glue, etc., it is weakly alkaline; the current method for treating kelp slag is to transport it to landfill, the second method is to make biological fertilizer, and the first method is to discard the kelp slag as waste , can easily cause environmental pollution and waste of resources. Although the second method reprocesses kelp slag to form organic fertilizers, this treatment is only primary treatment and does not make it more fully and effectively utilized.

Embodiment 1

[0024] Embodiment 1, the processing method of the seaweed protein feed of the present invention, select appropriate amount of kelp slag, put it into calcification tank or calcification pond and other devices or equipment for calcification, add 1%, 1.5% or 2 % hydrochloric acid to make the pH value reach 3, 3.5, 4 or 4.5, and then add 3%, 4%, 5%, 6% or 7% calcium chloride solution to make it flocculate completely and obtain calcified flocs ;In order to remove the excess calcium chloride in the calcified flocs, the calcified flocs can be put into the washing twisted cage, and the twisted cages are rinsed and cleaned with clean water, so that the calcium chloride in the calcified flocs is melted in the water and rinsed with water. The water is discharged together; the calcified flocs after washing and cleaning are dehydrated by a screw press to remove part of the water in the calcified flocs, so that the water content of the calcified flocs is 65%, 70% or 75%; The dehydrated calc...

Embodiment 2

[0025] Embodiment 2, one is to adopt the same technical method as in Example 1 to prepare the main raw material powder for later use; the second is to adopt the following technical method to prepare additional raw material powder for later use, and select Spirulina, natural sargassum and sargassum for use Any one of them or the mixture of the above-mentioned two or more seaweeds is selected as an additional raw material, the sediment is washed away, and then a refiner is used for refining, and clear water ( Dilution water) to dilute, preferably add kelp soaking water to dilute, finally obtain algae pulp with a solid content of 15%, 20%, 25% or 30%, store the algae pulp for 24, 30, 36, 40 or 48 hours , perform degradation treatment, and then use 80, 90 or 100 mesh filter devices to filter to obtain algae prizes that can be used for spray drying; using a spray dryer, the air supply pressure of the dryer can be 0.2, 0.25, 0.3, 0.35 or 0.4Mpa, the drying temperature can be 180°C, ...

Abstract

A seaweed feed rich in crude protein, I, Ca and P is prepared from kelp dregs through calsifying it to obtain the clacified floc, dewatering, baking, pulverizing to obtain class-one product, grinding seaweeds, spray drying, pulverizing, and mixing it with said class-one product to obtain class-two product.

Description

technical field [0001] The invention relates to a processing method of feed for livestock and poultry, in particular to a processing method of seaweed protein feed. Background technique [0002] In recent years, my country's breeding industry has developed rapidly, and the shortage of feed, especially the lack of protein feed, has become a more prominent problem. With the rapid growth of population and the large reduction of cultivated land, the contradiction between people and livestock and poultry competition for food has become increasingly acute. Therefore, finding new feed resources in algae grown in the ocean and processing them into protein feed has become a scientific research problem that needs to be solved urgently. There are tens of thousands of species of algae distributed in the ocean, including 10 phyla such as Chlorophyta, Phaeophyta, Cyanophyta, and Rhodophyta. These algae are rich in algae polysaccharides, proteins, fats, vitamins, minerals, and Physiologica...
