New maize germ extraction technology capable of improving purity of germs

Abstract

The invention discloses a new maize germ extraction technology capable of improving purity of germs. A beating plate type residue breaker, a square plansifter, a roller pulverizer, a square plansifter, a circulation air separator, a novel beating plate type residue breaker, a square plansifter and a circulation air separator are included. The new maize germ extraction technology overcomes the defect that due to a traditional maize degerming technology, the purity of the maize germs is low; the high-purity maize germs can be obtained on the premise that investment is not obviously increased; meanwhile, the tight breaking and separating combination method is adopted, the material amount is reduced step by step, then, later equipment loads are reduced step by step, the investment is reduced,and the running expense is reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a new process for extracting corn germs which can improve the purity of germs. Background technique [0002] The process of extracting corn germ is divided into wet method, dry method and semi-dry method. Among them, the disadvantages of the dry extraction corn germ process route are: low germ extraction rate, low germ purity, the advantage is low energy consumption and less investment in subsequent processes; the wet extraction corn germ process route has the advantages of high germ extraction rate, high germ purity, and disadvantages The reason is that the investment is large, the water content in the germ is too high, and subsequent drying treatment is required, and the energy consumption is high; the semi-dry method is a new technology improved and developed on the basis of the wet method. The disadvantage is that the germ extraction rate and germ purity are slightly lower than th...

Problems solved by technology

Among them, the disadvantages of the dry extraction corn germ process route are: low germ extraction rate, low germ purity, the advantage is low energy consumption and less investment in subsequent processes; the wet extraction corn germ process route has the advantages of high germ extraction rate, high germ purity, and disadvantages It is a large investment, the water content in the germ is too high, subsequent drying treatment is required, and the energy consumption is high; the semi-dry method is a new technology improved and developed on the basis of the wet method, and the advantage is that the investment is small, and the energy consumption of the subsequent treatment is low. The disadvantage is that the germ extraction rate and germ purity are slightly lower than the wet method, which is a process route mainly used in the industrialization of corn germ extraction in recent years

[0003] The traditional semi-dry corn germ extraction process is: plate-type slag breaker + vibrating sieve + roller mill + high square sieve + winnowing classifier or similar process, the purity of the germ is low, on the one hand, it affects the performance of subsequent processes. Consumption, also affect the by-product DDGS color

If the traditional technology wants to improve the purity of the germ, it must increase the crushing and separation processes, which will significantly increase the investment and operating costs.
