Buy Spray Dryer In Dairy Industry
Spray Dryer:
In the 1980s, a single-nozzle vertical pressure buy spray dryer was produced. Its application in the milk powder industry is a key link in promoting the technological progress of my country's milk powder industry, and it has laid a foundation for the rapid development of my country's milk powder industry. The milk powder produced by the spray drying method is a uniform powder product, which can be directly packaged as a finished product without drying, jelly, crushing and other processes. The production process of milk powder is mechanized, continuous and large-scale, and the quality of milk powder products is improved because the surface temperature of the material is not too high. The trend of increasing moisture content. The common types of dryers in contemporary my country include spray dryer in dairy industry, airflow dryers, fluidized bed dryers, fluidized bed spray granulation dryers, mesh belt dryers, etc.
Spray Dryers for the Dairy Industry:
In the production of dairy products in my country, the production of milk powder accounts for about 80% of the total output of dairy products, because milk powder is easy to store and transport. In the milk powder production process, the drying section is one of the most important links in milk powder production. The amount of water to be evaporated in the drying process is almost equal to the quality of the milk powder to be produced. Generally speaking, the production process of the product determines the production equipment and control system of the product, but the application of advanced equipment and control system can also change the production process of the product. The application of buy spray dryer in milk powder production is a typical example.
Introduction of dairy products:
Milk powder is a dairy product made by evaporating milk to a dry state. One of the purposes of drying milk is to preserve it. Milk powder has a much longer shelf life than liquid milk and does not require refrigeration because it has a low moisture content (2.5 - 5%). Another purpose is to reduce the volume to save transportation costs. Powdered milk is usually spray- or drum-dried. Spray drying is carried out in two stages. In the first stage, the pretreated milk is evaporated to a total dry solids content (%TDS) of 45–55%. In the second stage, the concentrated juice is pumped to a drying tower for final drying. Optimum viscosity of milk and correct %TDS are critical for the operation of evaporative and spray drying processes. To optimize the process and the quality of the finished product, online monitoring of the concentration and viscosity of the milk at the inlet of the evaporation tower and the sweetened condensed milk at the outlet is essential.
Application of spray dryer:
The Small scale spray dryer has broad-spectrum applicability to all solutions such as emulsions and suspensions, and is suitable for drying heat-sensitive substances such as Biological products, biological pesticides, enzyme preparations, etc., because the sprayed materials are only exposed to high temperature when they are sprayed into mist-like particles, so they are only heated instantly, which can keep these active materials from drying and their active ingredients are not damaged. .
At present, in the production of milk products in my country, the production of milk powder accounts for about 80% of the total output of all milk products, because milk powder is easy to store and transport. In the production process of milk powder, the monotonous section is one of the important links in the production of milk powder. The amount of water to be evaporated in the monotonous process is almost the same as the quality of the milk powder to be produced. Generally speaking, the production technology of the product determines the production equipment and control system of the product, but the application of advanced equipment and control system can also change the production technology of the product. The application of spray dryer in dairy industry in the production of milk powder is a typical example.
Advantages of spray dryer:
The Small scale spray dryer was used in the production of milk powder industry at the beginning of 1901, and it was only used in the production of milk powder industry in the 1920s, and it was only used in my country in the late 1940s. The early structure is attributed to the pressure box type (horizontal type), the atomization of the material is a two-fluid type, and the power consumption is large. By 1958, the Ministry of Light Industry in Heilongjiang Province implemented the animal-powered small pressure spray monotonous method to produce milk powder. The small scale spray dryer of these two methods were all flat-bottomed structures at the time, and the powder output was intermittent, and the powder was manually output once per shift.
In the mid-1960s, the structure method of the cone-bottom with a screw powder extractor (auger) appeared in the box-type pressure monotonous equipment. The first vertical multi-nozzle pressure small scale spray dryer was born in the early 1970s, and its appearance reduced the useful volume of the small scale spray dryer by nearly half, and it did not need to auger and continuously output powder. In the 1980s, a single-nozzle vertical pressure buy spray dryer was produced. Its application in the milk powder industry is a key link to promote the technical progress of my country's milk powder industry, and it has laid the foundation for the rapid development of my country's milk powder industry.
The spray monotonous process is that the material is pumped into the small scale spray dryer, and the atomizer loosens it into small droplets; the air is heated and sent into the monotonous chamber to mix and contact with the material mist; after the monotonous process is over, the monotonous products are separated. After storage or directly put into use. The milk powder produced by the spray monotonous method is a uniform powder product, which does not require technical processes such as drying, jelly, and damage. The surface temperature of the material will not be too high and the quality of the milk powder product will be improved. Therefore, the small scale spray dryer has played an immeasurable role in the production of the milk powder industry, and the monotonous moisture content tends to increase. However, spray monotony is a high energy consumption process, and because the product quality requirements after monotony are high, and the moisture content cannot be greatly fluctuated, it is required to strictly control operating parameters such as monotonous temperature, so the precise selection and operation and control of spray dryer in dairy industry are required. Systematic and rational planning is crucial to ensuring product quality, saving energy and reducing consumption. It not only makes due contributions to the advancement and development of science and technology in my country's dairy industry, but also drives and promotes the advancement and development of other work in science and technology. Make greater contributions to the economic development of the motherland.
