Description
Technical field
The present invention relates to the side that medicine and food technology field, raw material gelatin needed for being a kind of compacting soft capsule are recycled
Method.
Background technology
Medicine and the health food market share of more than half have been accounted for using soft capsule as the medicine of formulation and health food, and
And soft capsule with its it is distinctive liquid preparation can be enclosed in softgel shell, increasingly liked by pharmaceutical production producer and consumer
Love.But many enterprises it is latter in compacting soft capsule as will all suppress for the first time after the net glue that produces and the nearly half of remaining glue
Thrown away as discarded object.Also it has been documented from waste soft capsule and leftover bits and pieces and has reclaimed gelatin, but there is following lack in this method
Point：1. having used organic solvent in removal process, easy residual organic solvent in obtained gelatin is reclaimed, is had an impact to human body；
2. removal process is complicated, while having used substantial amounts of organic solvent to be washed and extracted, causes production cost high, can not expire
The requirement of sufficient existing process.
The content of the invention
The invention provides the method that raw material gelatin needed for a kind of compacting soft capsule is recycled, above-mentioned existing skill is overcome
The deficiency of art, it can effectively solve easy residual organic solvent in the gelatin that existing recovery method is obtained, have an impact to human body, production
Cost is high, and the problem of existing process is required can not be met.
The technical scheme is that realized by following measures：Raw material gelatin needed for one kind compacting soft capsule is reclaimed
The method utilized, is carried out in the steps below：The first step, the net glue produced during first time compacting soft capsule is rinsed,
Once net glue is obtained after rinsing well；Second step, once after net glue and the cutting of remaining glue and mixes, obtains once
Glue；3rd step, purified water is added in glue tank is changed and is heated to changing glue tank, the temperature of purified water is 68 DEG C in glue tank to be changed
During to 72 DEG C, a glue is added in glue tank to changing, the stirringization glue 1h to 2.5h in the case where temperature is 68 DEG C to 72 DEG C is obtained after reaction
Softgel shell glue, the addition of purified water is the 5% to 20% of a colloid amount；4th step, one time softgel shell is discharged with glue
After suppress soft capsule, the net glue that a softgel shell is produced with glue during compacting soft capsule carries out secondary recovery processing.
Here is the further optimization and/or improvements to foregoing invention technical scheme：
The net glue that an above-mentioned softgel shell is produced with glue during compacting soft capsule carries out secondary recovery processing in the steps below
Carry out：The first step, the net glue that a softgel shell is produced with glue during compacting soft capsule is rinsed, and is obtained after rinsing well
Secondary network glue；After second step, secondary network glue and the cutting of remaining glue and mix, obtain secondary glue；3rd step, is changing glue
In tank add purified water and to change glue tank heat, wait change glue tank in purified water temperature for 68 DEG C to 72 DEG C when, successively to
Change and glycerine and secondary glue are added in glue tank, the stirringization glue 1h to 2.5h in the case where temperature is 68 DEG C to 72 DEG C obtains secondary after reaction
Softgel shell glue, the addition of purified water is the 5% to 20% of secondary colloid amount, the addition of glycerine for secondary colloid amount 2% to
6%；4th step, secondary softgel shell is continued to suppress soft capsule with glue.
It is 3 centimetres to 5 centimetres that above-mentioned secondary network glue, which cuts into length, and remaining glue cuts into length for 3 centimetres to 5 lis
Rice, width are 3 centimetres to 5 centimetres, thickness is 0.3 centimetre to 1 centimetre, then will be after the secondary network glue after cutting and cutting it is surplus
Remaining glue is mixed, and obtains secondary glue.
The net glue that an above-mentioned softgel shell is produced with glue during compacting soft capsule is rinsed and centrifuged with purified water
Separation, obtains secondary network glue.
It is 3 centimetres to 5 centimetres that above-mentioned once net glue, which cuts into length, and remaining glue cuts into length for 3 centimetres to 5 lis
Rice, width are 3 centimetres to 5 centimetres, thickness is 0.3 centimetre to 1 centimetre, then will be after the once net glue after cutting and cutting it is surplus
Remaining glue is mixed, and obtains a glue.
The net glue produced during the above-mentioned soft capsule by first time compacting is rinsed and centrifuged with purified water, is obtained
Once net glue.
The stir speed (S.S.) of above-mentioned stirring glue is 25 revs/min to 35 revs/min.
The present invention does not use organic solvent compared with prior art in removal process, for the first time during compacting soft capsule
The net glue of generation and remaining glue, can continue to suppress soft capsule, the soft capsule of compacting does not have after reclaiming twice through the present invention
Machine dissolvent residual, will not be impacted to human body；And removal process of the present invention is simple, it is easy to operate；The present invention's is secondary simultaneously
The Gel strength of gelatin and Bo Shi viscosity meet professional standard in softgel shell glue, greatly reduce the waste of resource, reduction
Production cost.
