According to the present invention, according to GB standard using -4 glasss of method detections are applied, the viscosity of the capsule wall material solution is 50-
400mpas。
In the present invention, if the viscosity of the capsule wall material solution be more than the range be it is worthless, this be because
It is more than the range for gelatin viscosity, it is very big on dripping process and capsule quality influence, so, it is undesirable more than the range
?.
B, dripping capsule
The capsule wall material solution that step A is obtained is added in pill dripping machine glue case, allow its capsule wall material solution left standstill 20~
50min removes bubble removing, reuses pill dripping machine for its drop and crude capsule product is made;
The pill dripping machine used in this step is single channel pill dripping machine, it is current market sales of product, such as
The single channel pill dripping machine sold by Zhifu Plastic Machinery Co., Ltd., Tangshan City with trade name trickle irrigation drilling pill device.
When the present invention uses the single channel pill dripping machine, usually pill dripping machine glue box temperature degree and water dropper temperature are controlled respectively 50
~90 DEG C and 60~90 DEG C.If can all cause capsule wall material solution viscosity excessively high at a temperature below 50 DEG C or 60 DEG C, occur
Situations such as wire drawing, if temperature be higher than 90 DEG C if will lead to package fluid viscosity it is too low, influence dripping capsule quality.
C, crosslinking and cleaning
The crude capsule product that step B is obtained, which is added in crosslinked fluid, to be crosslinked, and is then removed using pure water cleaning
The grease stain being attached on its crude capsule product surface, it is then dry in swing rotating cage, obtain semi-finished product capsule;
According to the present invention, crude capsule product is crosslinked it should be understood that strengthening to crude capsule in crosslinked fluid.
In the present invention, the crosslinked fluid be by 1~2 parts by weight of crosslinking agent, 0.2~0.3 parts by weight pigment, 0.5~
The aqueous solution that 0.6 parts by weight toughener and 97~98 parts by weight water are formulated;
In the present invention, main function of the crosslinking agent in crosslinked fluid is to play a part of to strengthen, be dehydrated.
The crosslinking agent that the present invention uses is one or more selected from acetic acid, glutaraldehyde, potassium chloride, calcium chloride, sodium chloride, lemon
The crosslinking agent of lemon acid potassium, sodium citrate or calcium lactate, they are all current market sales of products, such as by Huangshan Bath
The glutaraldehyde that intelligent auxiliary chemicals Co., Ltd is sold with trade name glutaraldehyde;
In the present invention, main function of the pigment in crosslinked fluid is to colour for crude capsule or capsule color is kept not move back
Color.
The pigment that the present invention uses is one or more colors selected from brilliant blue pigment, lemon yellow pigment or allured red pigment
Element, they are all current market sales of products, such as are eaten by Zhengzhou sky food ingredient Co., Ltd with trade name
The brilliant blue pigment of the sale of toner brilliant blue 85% is sold by Zhengzhou sky food ingredient Co., Ltd with trade name Tatrazine 85%
The lemon yellow pigment sold, the temptation red sold by Zhengzhou sky food ingredient Co., Ltd with the edible temptation red 85% of trade name
Element;
In the present invention, main function of the toughener in crosslinked fluid is the moisture for guaranteeing crude capsule.
The toughener that the present invention uses is one or more toughener in D-sorbite, glycerol or polyethylene glycol,
They are all current market sales of products, such as by Jinan Xin Shunhang Biotechnology Co., Ltd with trade name D-sorbite
The D-sorbite of sale.
In the present invention, when other amounts of components are in the range, if dosage of crosslinking agent is lower than 1 parts by weight, by force
Change, dehydration are unobvious;If dosage of crosslinking agent is higher than 2 parts by weight, there is no strengthen dehydration;Therefore, crosslinking agent
Dosage is that 1~2 parts by weight are suitable, preferably 1.2~1.8 parts by weight;
When other amounts of components are in the range, if pigment dosage is lower than 0.2 parts by weight, capsule color is too shallow;
If pigment dosage is higher than 0.3 parts by weight, capsule color is too deep;Therefore, it is appropriate that pigment dosage, which is 0.2~0.3 parts by weight,
, preferably 0.22~0.28 parts by weight;
When other amounts of components are in the range, if toughener dosage is lower than 1 parts by weight, capsule is excessively crisp;If
Toughener dosage is higher than 2 parts by weight, then capsule is really up to the mark;Therefore, toughener dosage be 0.5~0.6 parts by weight be it is feasible, preferably
Ground is 0.52~0.58 parts by weight;
When other amounts of components are in the range, if water consumption is lower than 97 parts by weight, gelatin viscosity is too small;If
Water consumption is higher than 98 parts by weight, then gelatin viscosity is excessive;Therefore, water consumption be 97~98 parts by weight be it is appropriate, preferably
97.2~97.8 parts by weight;
According to the present invention, the thick capsule product carries out 20~80min of crosslinking under conditions of 10~60 DEG C of temperature.
In this step, the thick capsule product cleaned with pure water is in swing rotating cage in 20~100r/ of revolving speed
Min, relative humidity 30~50% with 20~30 DEG C of temperature under conditions of be dried, removing is attached to its crude capsule product table
Grease stain on face.
The swing rotating cage that the present invention uses is current market sales of product, such as is had by Wuxi ring precious jade machinery science and technology
Limit company is with the product of the swing rotational molding machine sale of trade name.
D, balance and screening
The semi-finished product capsule washes of absolute alcohol for allowing step C to obtain is balanced in being then placed between balancing, then sieves
Divide and selected with lamp, then obtains the capsule with degrading resistance property.
According to the present invention, the basic role that cleaning semi-finished product capsule balances between balance is volatilization dehydrated alcohol.
Certain temperature and certain humidity range are to maintain between the balance, for balance after washes of absolute alcohol half at
Product capsule.
It is flat under conditions of 10~40 DEG C of equilibrium temperature and relative humidity 20~70% between balance to clean semi-finished product capsule
Weighing apparatus 8~30 hours.
In this step, the semi-finished product capsule of balance is under conditions of 10~40 DEG C of temperature with relative humidity 20~70%
Screening is carried out to select with lamp.
In the present invention, screening be using by the new Machinery Co., Ltd. of Xinxiang City's Condar with trade name stainless steel punched-plate net
The stamped sieve of standard screen sale carries out partial size screening, obtains the capsule of 3.3~3.6mm of partial size.These capsules are then in lamp channel selection
The underproof product of appearance is with the naked eye picked out under fluorescent lamp.
Dry breakage rate and screening breakage rate have been carried out to the capsule being prepared using quantitative approach according to national standard
Detection, testing result are listed in Table 1 below.
[beneficial effect]
It is compared with the prior art, the invention has the following advantages:
1, crosslinking time of the present invention is shorter, and the crude product obtained after the completion of being crosslinked is harder compared to prior art, is easy
Realize industrialization.
2, crude product of the present invention has resist processing characteristic, improves capsule finished product yield.
3, finished capsule product of the present invention due to degrading resistance property, occur when solving following process it is rotten, become
Shape even ruptures leakage problems.
4, product of the present invention overcomes the harsh use environment requirement of existing capsule, does not adapt to each department climate difference institute
Bring puzzlement, at the same overcome product produce and sell, reprocessing during ease back, deform, leakage, the quality such as empty pearl are asked
Topic.Product quality risk is reduced, guarantees consumer experience sense.
