Description

Mechanical agitation type circulation complex ferment reactor
Technical field
The utility model relates to a kind of biological fermentation reaction unit, relates in particular to a kind of mechanical agitation type circulation complex ferment reactor, mainly is applicable to by biological fermentations such as methyl alcohol system methyl alcohol albumen and reacts.
Background technology
China's feed industry needs methyl alcohol albumen about more than 5,000,000 tons every year at present.And the industry of present domestic methyl alcohol albumen still is in the starting stage, does not set up production equipment as yet.Therefore, the simple fish meal that relies on farm crop such as plantation grain class or marine fishery production satisfies the mankind and far can not satisfy the growing market requirement to proteinic demand.Synthetic single cell protein (single cell protein) is one of important channel that solves China's food problem.And the methyl alcohol single cell protein can be a raw material from coal or Sweet natural gas, makes via the methyl alcohol biochemical reaction.It contains rich in protein, amino acid and multivitamin, and product safety and nontoxic can promote livestock to produce and improves efficiency of feed utilization.Owing to produce traditional mode of production pattern and marine fishery resources that methyl alcohol albumen need not rely on the arable land, with methyl alcohol is that raw material synthesizing methanol albumen is as high-octane concentrated feed, per 1 ton of methyl alcohol albumen can be saved 3.5 tons in grain, can prepare 10 tons of feeds, and social benefit and economic benefit are all very considerable.So development methyl alcohol albumen is one of important channel that solves China's aquaculture and foodstuffs industry protein shortage problem.
