Description
Technical Field
The invention relates to the technical field of feed production equipment, in particular to continuous DDGS drying equipment.
Background
In recent years, with the increase of domestic requirements for meat poultry, the import of DDGS in China is increased dramatically, and the DDGS becomes the first large market of the export of DDGS in the United states. However, the domestic research on DDGS is far from keeping up with the development of market demand, and is in the starting exploration stage in the research and production of DDGS feed drying equipment.
The influence of DDGS import on the Chinese feed industry is researched, and the fluctuation of the product price in the upstream and downstream markets is directly influenced. The DDGS is used as a feed raw material, and can relieve the great demand of the production of Chinese animal protein products on the feed. With the revocation of the anti-tipping survey of DDGS in China, the import of this material will be unavoidable and the use in feed will rise.
The appearance of DDGS increases a choice for China. DDGS refers to dried distillers grains and raffinate, which can be used as the main ingredient of feed, and can produce about 0.85-1 ton of DDGS (yellow-season, vengean-glary, 2010) per 1 ton of fuel ethanol. The corn can be continuously used for producing feed after being used for ethanol processing, and the demand pressure of the corn is directly reduced. Despite the rapid development of the ethanol processing industry in our country in recent years, aflatoxins present in corn remains a hindrance to the use of DDGS produced by our country as a feed material.
In order to overcome the defects in the domestic drying and preparation of DDGS, on one hand, the domestic implementation of a standard production process and a storage facility for providing a sufficient high-humidity resistant production environment are required; on the other hand, enterprises are required to actively develop DDGS research and development.
Compared with the original first generation adopted drying process, 4-6 sections of dryers are connected with a pull rod and a screw spline sleeve through a machine barrel flange to form an integrated type, the integrated type is similar to a building block type, material connection between each section of dryer needs to be conveyed through a spiral feeding machine, heat and nutrient components are wasted and lost in the conveying process, and continuous drying cannot be carried out, so that the nutrient components in the DDGS feed can be damaged, the grade of the DDGS feed is reduced, and the drying capacity is limited.
