Description
Technical field
The present invention relates to the depilatory used in the poultry course of processing, be specifically related to poultry level depilating resin and preparation method thereof.
Background technology
At present, in China's poultry class processing, the operation pulling out little Mao after sloughing feather wastes time and energy, and therefore many processors often take rosin to pull off the feather of.And rosin is the mixture based on resinous acid, resinous acid is the monocarboxylic acid containing two double bonds with a luxuriant and rich with fragrance skeleton of three rings, due to the existence of active group, character is active, easily be oxidized in atmosphere, the speed be oxidized can be accelerated when higher temperature, generate superoxide or hydroperoxy-compound, because rosin needs through repeatedly heating in epilation use procedure, thus reactive group can be made to carry out the oxidizing reaction of various complexity, discharge toxic substance, these toxic substances can be permeated by cortex and remain in animal body, harm human consumer is healthy, therefore, country has expressly provided and has forbidden to use rosin depilation.
Ester gum, be the additive that current China is allowed for poultry depilation, it is accumulated hardly in animal body, does not decompose, and safety performance is higher.In prior art, if publication No. is the patent of invention of CN1826913A, disclose a kind of compound livestock and poultry trichogen, it is formulated by rosin glyceride 75 ~ 95%, animal grease 3 ~ 15%, paraffin 2 ~ 10% by weight percentage.The described trichogen of this invention causes cost higher because using rosin glyceride, its fusing point (i.e. softening temperature) is at 85 ~ 90 DEG C in addition, when heating use procedure, temperature is often more than 150 DEG C, not only energy consumption is higher, and such service temperature also easily scalds product, the outward appearance of the rear poultry of impact processing and quality.Publication No. is that the patent of invention of CN102630728A discloses a kind of compound fowl industry trichogen, and it is formulated by food grade ester gum 65 ~ 75 parts, food-grade paraffin wax 22.5 ~ 29 parts, food grade silicone grease 0.5 ~ 1.5 part and animal grease 5 ~ 10 parts.The described trichogen of this invention adopts food grade materials, and safer, it has good hair removal effect to bird, but is not very desirable to the hair removal effect of domestic animals, also there is the higher deficiency of cost in addition.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of cost is lower, softening temperature suitably, be applicable to poultry depilation and use and good poultry level depilating resin of hair removal effect and preparation method thereof.
Poultry level depilating resin of the present invention, by weight, be made up of the raw material of following weight parts:
Rosin 50 ~ 80 parts, glycerine 2 ~ 7 parts, sucrose 2 ~ 7 parts, oxalic acid 1 ~ 5 part, plam oil 10 ~ 18 parts, Viscotrol C 2 ~ 5 parts.
The weight part of above-mentioned each raw material is preferably:
Rosin 60 ~ 70 parts, glycerine 3 ~ 5 parts, sucrose 3 ~ 5 parts, oxalic acid 2 ~ 4 parts, plam oil 10 ~ 15 parts, Viscotrol C 3 ~ 4 parts.
In the raw material of poultry level depilating resin of the present invention, rosin is primary rosin, and glycerine, sucrose, oxalic acid, plam oil and Viscotrol C are food grade materials.
The preparation method of above-mentioned poultry level depilating resin is: take the rosin of proportional quantity, plam oil and Viscotrol C and drop into reactor, pass into protection of inert gas, be heated to material dissolution, start stirring, be warming up to 150 ~ 170 DEG C, drop into the oxalic acid of proportional quantity, sucrose and glycerine, be warming up to 200 ~ 220 DEG C, insulation reaction 1 ~ 2h; Then continue to be warming up to 260 ~ 270 DEG C, insulation reaction 2 ~ 4h, start the softening temperature and the acid number that sample detection sample afterwards, when the softening temperature of sample reach 60 ~ 75 DEG C, acid number < 10mgKOH/g time, stop heating, vacuumize 5 ~ 10min, then lower the temperature, discharging, namely obtains poultry level depilating resin; When the softening temperature of sample and acid number do not reach requirement, continue the temperature reaction at 260 ~ 270 DEG C, until the softening temperature of sample and acid number do not reach requirement.
In above-mentioned preparation method, the speed of intensification preferably controls, at 8 ~ 10 DEG C/h, to be more preferably 10 DEG C/h.
In above-mentioned preparation method, described rare gas element can be other rare gas elementes such as nitrogen, argon gas or helium.In above-mentioned preparation method, discharging when being normally cooled to 200 ~ 220 DEG C.
In above-mentioned preparation method, after the cessation of the heating, keep 5 ~ 10min normally by reaction kettle for vacuumizing to 0.2 ~ 0.4MPa, with by the extraction such as heavy turpentine, glycerine remaining in reaction system.
In the method for the invention; reaction is carried out under protection of inert gas; while reaction system carries out reacting at 260 ~ 270 DEG C; heavy turpentine overwhelming majority volatilization remaining in rosin; combine the vacuum pumping after stopping heating again; the composition such as heavy turpentine in reaction system is extracted out, makes the product that is obtained by reacting in use safer.
Softening temperature of the present invention 60 ~ 75 DEG C is the result adopting ring and ball method to detect.
Compared with prior art, the present invention adopts based on rosin, and add the solvent temperature of plam oil and Viscotrol C reduction rosin, after rosin dissolves, plam oil, Viscotrol C and rosin carry out addition and esterification modification, the molecular weight of augmenting response thing; The diprotic acid oxalic acid introduced and sucrose and polyvalent alcohol glycerine carry out esterification to modified rosin, and to obtain having a certain amount of cancellated macromolecular resin, this gained macromolecular resin viscous force is strong, sticking power good, has good hair removal effect; In addition, gained macromolecular resin has suitable softening temperature (60 ~ 75 DEG C), less energy consumption during use, and due to softening temperature lower, when pulling off the feather of for poultry, namely temperature can carry out epilation operation at 120 DEG C, and product will be caused to produce other toxic substance because of carbonization etc., the use of product is safer.
