Embodiment 1

[0014] Concentration: send the amino acid solution into the MVR evaporator, the concentration temperature in the MVR evaporator is 58°C, when the concentrated solution reaches 24 °Bé in Baume, the concentration stops, and the amino acid concentrated solution is obtained, and the amino acid concentrated solution is sent to the filter for filtration , The filtered solid can be directly used as fertilizer, and the liquid part is amino acid concentrate, whose volume is 48% of the initial volume. Granulation: Put the amino acid concentrate into the mixing tank, add water retaining agent with 21% of the liquid weight in the tank into the tank, the water retaining agent stirs quickly and absorbs water to make the amino acid into uniform particles, and sends the uniform amino acid particles into the vibrating screen for sieving, sieving It is divided into two parts with a diameter of more than 2mm and less than 2mm. First, the amino acid particles with a diameter of more than 2mm are s...

Embodiment 2

[0016] Concentration: send the amino acid solution into the MVR evaporator, the concentration temperature in the MVR evaporator is 60°C, stop the concentration when the concentrated solution reaches 24.5 °Bé in Baume, and get the amino acid concentrated solution, then send the amino acid concentrated solution to the filter for filtration , The filtered solid can be directly used as fertilizer, and the liquid part is amino acid concentrate, whose volume is 50% of the initial volume. Granulation: Put the amino acid concentrate into the mixing tank, add water retaining agent 20% of the liquid weight in the tank into the tank, the water retaining agent stirs quickly and absorbs water to make the amino acid into uniform particles, and the uniform particles of amino acid are sent to the vibrating screen for screening. It is divided into two parts with a diameter of more than 2mm and less than 2mm. First, the amino acid particles with a diameter of more than 2mm are sent to the packag...

Embodiment 3

[0018] Concentration: Send the amino acid solution into the MVR evaporator, the concentration temperature in the MVR evaporator is 58-62°C, when the concentrated solution reaches 25 °Bé in Baume, the concentration stops, and the amino acid concentrated solution is obtained, and the amino acid concentrated solution is sent to the filter Machine filtration, the filtered solid can be directly used as fertilizer, and the liquid part is amino acid concentrate, whose volume is 52% of the initial volume. Granulation: Put the amino acid concentrate into the mixing tank, add water retaining agent with 19% of the liquid weight in the tank into the tank, the water retaining agent stirs quickly and absorbs water to make the amino acid into uniform particles, and the uniform particles of amino acid are sent to the vibrating screen for sieving, sieving It is divided into two parts with a diameter of more than 2mm and less than 2mm. First, the amino acid particles with a diameter of more than...

Abstract

The invention discloses a granulation method of an amino acid solution and belongs to the field of amino acid production. The granulation method utilizes an amino acid solution as a raw material and comprises concentration, granulation and packaging. The granulation method utilizes general equipment, has simple processes, is free of a high temperature and high pressure reaction, and realizes room temperature granulation and mass production of amino acid particles. The product is mainly used for preparation of a variety of organic and inorganic composite fertilizers.

Description

[0001] Technical field: [0002] The invention belongs to the field of amino acid production, in particular to a method for granulating an amino acid solution for fertilizer. [0003] Background technique: [0004] At present, the production of amino acids in China generally uses poultry feathers as raw materials. After hydrolysis, a solution containing amino acids is obtained. This part of the solution is sprayed granulated or spray-dried to obtain a solid product. The spray granulated or spray-dried process is one The big problem is the high energy consumption, the difficulty of tail gas treatment, and the high cost of environmental treatment. The advantage is that the product has high purity and can be used in medicine and food. However, in occasions with low requirements, a method of granulating amino acid solution with low energy consumption, no pollution, and no need to treat tail gas can be used. This method has shown great advantages especially in the production of amin...
