Technical field
The invention belongs to enzyme engineering field, specifically, the present invention relates to a kind of washing enzyme granulation preparations.
Background technology
Washing is the widely used enzyme preparation of existing market with enzyme, special since it can increase substantially washing dirt-removing power
It is other to protides dirts such as bloodstain, sweat stain, milk stain, oil stains, there is unique washing effect.Conventional washing is industrially with solid
Particle shape formula is added in washing powder, and dirt-removing power is washed, but dust, vehicle are easily generated when processing prepares enzyme granulate to enhance it
Between residual dust can cause the allergic reaction of contact to part population, such as long-term excessive contact can cause can be to human body skin
Skin, eyes and schneiderian membrane membrane tissue damage.The washing of existing coating type is with enzyme generally existing is expensive, particle homogeneity
Difference, the problems such as disintegration rate is low.
Novozymes Company of Denmark and company of American Energy Saving section do a lot of work in terms of washing enzyme, domestic and international mainstream
Prilling is mainly the equipment such as centrifugal granulator combination fluid bed, although the technique can obtain that disintegrating property makes moderate progress
Grain, but centrifugal granulator and fluid unit are expensive, it is high that craftsmanship is required, product yield is relatively low and product particle is equal
Evenness is poor.In addition centrifugal granulating and fluid bed generate a large amount of enzyme powders in preparation process is processed, and workshop residual dust is to part
Crowd can cause the allergic reaction of contact, and such as long-term excessive contact can cause can be to human skin, eyes and schneiderian membrane film
Tissue damages.
Those skilled in the art are dedicated to developing a kind of preparation process of new coating type enzyme granulate.So as to safety,
It is easy, efficient to prepare coating type washing enzyme, it realizes self raising flour dirt or is granulated without dust, improve the stability of production technology,
Reduce influence of the human factor to product quality and yield and realize granzyme and washing powder have preferable mixture homogeneity,
Enzyme granulate fater disintegration, longer holding time, while can also reduce granulation production manufacturing cost.
