Embodiment 1

[0004] Embodiment 1 is concentrated: amino acid solution is sent into MVR evaporator, the concentration temperature in MVR evaporator is 58 ℃, when concentrated solution reaches Baume degree 24 ° of Bé, concentration stops, obtains amino acid concentrated solution, and amino acid concentrated solution is sent into. Filtered by a filter, the filtered solids can be directly used as fertilizer, and the liquid part is amino acid concentrate, and its volume is 48% of the initial volume. Granulation: The amino acid concentrate is sent to a stirring tank, and a water-retaining agent with a weight of 21% of the liquid in the tank is added to the tank. The water-retaining agent quickly stirs and absorbs water to make the amino acid into uniform particles. It is divided into two parts with a diameter of more than 2 mm and a diameter of less than 2 mm. First, the amino acid particles with a diameter of more than 2 mm are sent to the packaging machine for packaging and then discharged, and...

Embodiment 2

[0005] Embodiment 2 is concentrated: amino acid solution is sent into MVR evaporator, the concentration temperature in MVR evaporator is 60 ℃, when concentrated solution reaches Baume degree 24.5 ° of Bé, concentration stops, obtains amino acid concentrated solution, and amino acid concentrated solution is sent into. Filtered by a filter, the filtered solids can be directly used as fertilizer, and the liquid part is amino acid concentrate, and its volume is 50% of the initial volume. Granulation: The amino acid concentrate is sent to a stirring tank, and a water-retaining agent with a weight of 20% of the liquid in the tank is added to the tank. The water-retaining agent quickly stirs and absorbs water to make the amino acid into uniform particles. It is divided into two parts with a diameter of more than 2 mm and a diameter of less than 2 mm. First, the amino acid particles with a diameter of more than 2 mm are sent to the packaging machine for packaging and then discharged, a...

Embodiment 3

[0006] Embodiment 3 is concentrated: the amino acid solution is sent into the MVR evaporator, and the concentration temperature in the MVR evaporator is 58-62 ° C, and when the concentrated solution reaches Baume degree 25 ° Bé, the concentration is stopped to obtain the amino acid concentrated solution, and the amino acid concentrated solution is obtained. It is sent to a filter for filtration, and the filtered solids can be directly used as fertilizers. The liquid part is amino acid concentrate, and its volume is 52% of the initial volume. Granulation: The amino acid concentrate is sent to the stirring tank, and a water-retaining agent with a weight of 19% of the liquid in the tank is added to the tank. The water-retaining agent quickly stirs and absorbs water to make the amino acid into uniform particles. It is divided into two parts with a diameter of more than 2 mm and a diameter of less than 2 mm. First, the amino acid particles with a diameter of more than 2 mm are sent ...

Abstract

The invention discloses an amino acid solution granulating method. The method belongs to the field of amino acid production. The raw materials used by the production method comprise an amino acid solution, and a finished product is prepared by the work procedures of concentrating, granulating, packaging and the like. The amino acid solution granulating method disclosed by the invention has the advantages: general equipment is utilized, a production technology is simple, high temperature and high pressure reaction is avoided, granulation at normal temperature is achieved, amino acid particles can be batch produced, and the product is mainly applied to preparing varieties of organic-inorganic compound fertilizer.

Description

technical field [0001] The invention belongs to the field of amino acid production, and in particular relates to a method for granulating an amino acid solution for fertilizers. Background technique [0002] At present, domestic production of amino acids generally uses poultry feathers as raw materials. After hydrolysis, a solution containing amino acids is obtained. This part of the solution is then sprayed and granulated or spray-dried to obtain solid products. The big problem is high energy consumption, difficult exhaust gas treatment, and high cost of environmental treatment. The advantage is that the product has high purity and can be used in medicine and food. However, a method of granulating amino acid solution with low energy consumption, no pollution, and no need to deal with exhaust gas can be used in occasions with lower requirements. This method shows great advantages especially in the production of amino acid granules for fertilizers. The core equipment of the ...
