About 10,000,000 tons every year of China's cassava production, and increased every year with about 30% ratio.Cassava contains a large amount of starch,
It is widely used in producing starch and fermenting and producing alcohol.In cassava process, a large amount of manioc waste is with tapioca and wine
The production of essence and generate, the manioc waste dry weight of annual China's tapioca processing has 300,000 tons, plus processing other productions such as alcohol
The manioc waste of product adds up 1,500,000 tons, by taking one is produced per year 30,000 tons of starch processing large enterprises as an example, about generates 60,000 tons every year
Wet manioc waste, needs 15 mu of slag bath of mating land occupation, and when peak needs to accumulate 30,000 tons of wet slag.A large amount of processing solid waste,
On the one hand the waste of land resource is caused；On the other hand, long-term storage leads to manioc waste fermentation corruption, not only makes cassava materials
Utilization rate is low, and makes a very bad impression to surrounding enviroment, thus highlights to the comprehensive utilization of manioc waste important.
Currently, in the prior art, the processing method of manioc waste is mainly that biogas utilization and fodder utilize, biogas utilization skill
Though art can reach the requirement of environmental protection, there is processing time longer defect；During fodder utilizes, moist manioc waste
It easily ferments, it is necessary to be stored by dewatered drying, but the process need to expend mass energy, cause to increase cost input height.
Therefore, it needs to seek the new method that a kind of pair of waste cassava residues are handled, it is above-mentioned to solve the problems, such as.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
Summary of the invention

It is uniformly mixed；
(2) it keeps temperature to be 53~56 DEG C to place 10~12 days；
(3) be passed through vapor, be then dehydrated to get.
Preferably, the mass concentration of calcium hydroxide solution is 30~35% in step (1).
Preferably, waste cassava residues and calcium hydroxide solution mass ratio are 0.3~0.5:1~1.2 in step (1).
Preferably, vapor intake is 1200~1300m in step (3)3/ h, is passed through 20~30min.
Compared with prior art, the invention has the following beneficial effects:
The method of the present invention can have rapidly and efficiently, and process environment is friendly, and gained waste cassava residues can make feed after processing
Or fertilizer, gained liquid can recycle after except alkali after processing, and added value of product is high, and processing cost is low；Into one
Step has saved the energy, has method simple, and can be suitable for the characteristics of industrializing large-scale application.
