Though nut, with full of nutrition famous, nut drink is also very popular, nut will be processed into stable system mouthfeel The pure and sweet beverage of fine and smooth taste is not easy to.At present, the raw material of nut beverage available on the market, most of is only single The nut of kind or the form arranged in pairs or groups using peanut or soybean with nut.Beverage prepared by the nut of single variety it is steady The indexs such as qualitative, mouthfeel and taste are poor, and beverage prepared by pure nut is substantially more expensive, it is difficult to adapt to popular need When wanting, and preparing beverage with nut collocation using soybean, the fishy smell of soybean easily influences the mouthfeel of nut beverage.In addition, city There are a small number of nut composite beverages, i.e., the beverage prepared using the processing of a variety of nuts on field.This beverage is as a result of more Kind nut, production cost is higher, and there is also some shortcomings in the refining process of nut, such as:(1) defibrination mistake It is also easy to produce high temperature in journey, and temperature is excessively high necessarily so that the grease in nut aoxidizes, and influences the fragrance of nut beverage;(2) The nut of some kinds is difficult to carry out defibrination process, for example, bar denier wood benevolence, since its fiber content is higher, it is difficult to grind pulp Liquid, and substantial amounts of heat is more also easy to produce in process of lapping.
Chinese invention patent, publication No.:CN106879899A, publication date:On June 23rd, 2017, disclose a kind of cheese Nut beverage and preparation method thereof.A kind of cheese nut beverage of the disclosure of the invention, by weight, is made of following raw material: 5~15 parts of cheese, 20~30 parts of nut, 0.02~0.04 part of thickener, 0.03~0.05 part of preservative, happy 5~15 parts of agent, Remaining is pure water.The nut is fibert, pinenut, American pistachios, sunflower seed, and fibert, pinenut in the nut are opened Heart fruit, the weight ratio of sunflower seed are 1:1:2:2 or 1:2:1:2.A kind of cheese nut beverage preparation side of the Invention Announce Method comprises the following steps:S10, select full, free from insect pests, without the nut then to go mouldy, remove shell, it is spare that nut kernel is made; S11, the nut kernel handled well in step S10 is put into oven, oven stops heating after being warming up to 140 DEG C~150 DEG C, cold But to room temperature, open oven and pour out ripe nut kernel;S12, by ripe nut kernel with warm water impregnate 4~5 it is small when, be then beaten, use 200 mesh sieves are filtered, and it is spare that nut slurry is made;S13, nut is starched to add in pure water and heat and is boiled, add in cheese, happy agent, thickening Agent, preservative stir evenly, by filtrate tinning, up to the cheese nut beverage after sterilization.Its shortcoming is:(1) it is warm Although nut kernel after water immersion is easy to smash prepares slurries, but the taste flavor of the nut slurry prepared is also declined;(2) Specific beating process is not disclosed in the program, and different nut species is suitable for different beating process, and beating process is different The slurries mouthfeel of preparation would also vary from, such as:The high nut of fat content is suitable for the technique of mill defibrination, and grease contains It measures and low is unsuitable for grinding refining process;General beater is suitable for family expenses, and needs to impregnate nut before being beaten, and soaks Bubble then often influences the original flavor taste of nut, and colloid mill is suitable for industrial production, but colloid mill is in process of lapping The high temperature of generation easily causes the Oxidation of Fat and Oils in nut.
Chinese invention patent, notification number:CN105029602B, publication date:On July 4th, 2017, disclose a kind of walnut The production technology of drink, including peeling, defibrination, feed liquid allotment, filtering and homogeneous, the water temperature of defibrination is 70~90 DEG C, the amount ratio of walnut kernel and water is 1kg:3~7L;Slurries refinement is also carried out after defibrination:Appropriate hot water is added into slurries, Further reduce granularity through high speed shear, the addition of the hot water is the 10~50% of the slurry volume, the hot water Temperature is 70~90 DEG C;When carrying out slurries refinement, surfactant and lywallzyme are also added in the slurries, is being carried out Ultrasonic wave is also applied with during high speed shear;The frequency of the ultrasonic wave is 50~70KHZ, applies the high speed shear mistake of ultrasonic wave Cheng Chixu 5~20 minutes;The surfactant be selected from single, double tristerin, polyglycerol ester, stearoyl lactate, One or more in sucrose ester and Sodium Caseinate, the 0.1~10g of surfactant added in every liter of slurries, lywallzyme 1~25g.The defibrination refines walnut kernel in a manner that more colloid mills are connected step by step.Its shortcoming is:(1) work Beverage prepared by skill, mouthfeel is single, and cost is higher, it is difficult to adapt to popular needs;(2) deposited during the refining process In Oxidation of Fat and Oils, the problem of causing nutrition leak.
The content of the invention
1st, to solve the problems, such as
It causes to grind since nut fat content is few, content of cellulose is high for during existing nut composite beverage defibrination Mill is difficult, it is higher that heat is led to the problem of during defibrination, of the invention to provide a kind of nut composite beverage refining process.It First by a variety of nuts premix uniformly after carry out defibrination process again, so as to the balanced fat content of different category nuts so that mill Slurry process obtains sufficient lubrication.
2nd, technical solution
To solve the above problems, the present invention adopts the following technical scheme that.
A kind of nut composite beverage refining process, comprises the following steps:
S1, premix:Nut composite benevolence is pre-mixed uniformly;
S2, corase grinding:It is roughly ground using level-one stone mill;
S3, fine grinding:It is refined using two level colloid mill;
The uniform micronization processes of S4, slurries:Nut slurries are prepared using the uniform grinding of two pairs of rollers progress is squeezed.
This programme is overcome using the process program of classification defibrination refinement slurries in existing refining process, and especially single-stage is ground The problem of temperature height causes Oxidation of Fat and Oils present in refining process first uses level-one stone mill in this programme to nut composite Corase grinding has the advantages that following three by the way of the fine grinding of two level colloid mill again:(1) during nut kernel being worn into slurries, Frictional heat amount between mill and nut kernel causes temperature to raise, by the way of being roughly ground using colloid mill, using stone mill High temperature is not likely to produce during corase grinding;(2) defibrination is in the process usually beaten nut slurries more broken, and the heat of release is more, Temperature is higher, and the grease in turn resulted in nut slurries is aoxidized, and nutrition is caused to lose, thus this programme is first using corase grinding Again by the way of fine grinding, heat is classified and is discharged, is not easy that temperature is made significantly to raise, helps avoid grease and aoxidized, this The purpose of scheme corase grinding is that nut kernel is worn into nut slurries without pursuing particle sice in serosity, and the heat of release is less, in addition stone mill The rising of mill temperature is slower, thus temperature is relatively low always in rough grinding pass;(3) nut of high fat content is during defibrination The grease of release promotes the lubrication between mill and nut kernel, thus nut composite is first premixed and uniformly roughly ground again, is contributed to Balance the fat content in nut composite material so that defibrination process is more smooth, solves in the prior art to each category nut During the independent defibrination of benevolence due to fat content is low in nut kernel, fiber content it is high cause between mill and nut kernel frictional force big and The problem of release is substantial amounts of hot.In addition, when nut slurries prepared by level-one stone mill corase grinding enter back into two level colloid mill, there is stream The characteristics of dynamic property is good, charging is stablized, and when colloid mill again refines the slurries with certain fineness at this time, the heat of release Also less, the grease being not easy into nut slurries aoxidizes.Furthermore the slurries after the fine grinding of two level colloid mill are by squeezing Evenly, the slurries of preparation are finer and smoother, improve the mouthfeel of nut beverage for the granularity of nut kernel particle after two pairs of rollers processing.
Further, the level-one stone mill grinds for white sand rock, and white sand rock mill is of good quality, not easy to crack, and defibrination The temperature of mill is relatively low in the process.
Further, when the level-one stone mill is roughly ground, speed of grinding plate is below 33r/min.During defibrination, Speed of grinding plate is faster, and the easier aggregation of the heat of the generation that rubs generates high temperature, by when debugging that find speed of grinding plate be 33r/min, For the temperature of stone mill always between 40~50 DEG C, this temperature range does not easily cause Oxidation of Fat and Oils.
Further, cooling-water duct is provided in the two level colloid mill, cooling water is connected in the cooling-water duct, The temperature of the cooling water is 3~12 DEG C, and cooling water forms chilling to colloid mill, during colloid mill defibrination Leading to the problem of substantial amounts of heat causes instantaneous temperature to raise.
Further, for the particle in nut slurries sufficiently is squeezed refinement, the quantity for squeezing two pairs of rollers is together More than.
Further, particle sice in serosity of the slurries of level-one stone mill corase grinding generation after the fine grinding of two level colloid mill is 100~150 Mesh, the particle sice in serosity after squeezing two pairs of rollers and uniformly grinding are promoting nut drink for the nut slurries more than 200 mesh, refined step by step The defects of original defibrination refinement heat production is excessive is also overcomed while the mouthfeel of material.
Further, the nut composite benevolence includes walnut kernel, bar denier wood benevolence, hazelnut kernel and cashew nut kernel.
This programme arranges in pairs or groups walnut kernel, bar denier wood benevolence, hazelnut kernel and a cashew nut kernel mixing in proportion, enriches the nutrition of nut slurry Ingredient.In addition, the high nut kernel of fat content is easier to carry out defibrination, such as walnut kernel, and for the low nut of fat content Benevolence is then not easy to carry out defibrination, such as bar denier wood benevolence, this is because during defibrination, cannot centainly generate high temperature, and Ba Danmu Fat content in benevolence is relatively low, and fiber content is up to more than 18%, and when this is resulted in individually to bar denier wood benevolence defibrination, friction is released The heat put is larger, and the fiber in bar denier wood benevolence is not easy to be grated, and is easily filtered out that nutrition is caused to lose in subsequent technique It loses.For solve the problems, such as it is above-mentioned be not easy the nut kernel low to fat content and carry out defibrination, this programme is before refining step, first Walnut kernel, bar denier wood benevolence, hazelnut kernel and cashew nut kernel premix is uniform, and the nut kernel of so high fat content is during defibrination The grease of release has lubricating action, reduces frictional force, is not easy heat production, also promotes the smooth progress of refining step.
Further, in percentage by weight, the nut composite benevolence includes 3~8 part, bar denier wood benevolence 3~8 of walnut kernel 1~5 part of part, 1~5 part of hazelnut kernel and cashew nut kernel, according to the ratio of this programme first to walnut kernel, bar denier wood benevolence, hazelnut kernel and waist Kernel premix uniformly then defibrination, balances the fat content in nut composite material so that uniformly mixed compound heavily fortified point Fruit material is easier to defibrination.
Further, premixed again after walnut kernel, bar denier wood benevolence, hazelnut kernel and a cashew nut kernel being toasted out fragrance respectively, By being toasted to removing the peel clean nut kernel, nut kernel is made to distribute fragrance, then carries out defibrination again, this mode helps In the taste flavor of enhancing nut beverage, in production practices, baking degree is determined regarding nut kernel raw material condition, generally by nut Benevolence is baked to four to medium rare.
Further, walnut kernel and bar denier wood benevolence first at 80 DEG C are toasted, is then toasted at 120 DEG C~135 DEG C, it will Hazelnut kernel and cashew nut kernel toast at 125 DEG C~165 DEG C.
The moisture content of the general nut kernel by decladding decortication processing is higher, and directly grinding can be to the flavor mouth of nut beverage Sense has an impact, and is divided into two stages of low temperature and high temperature, low-temperature bake rank to the baking of walnut kernel and bar denier wood benevolence in this programme Section is in order to which the moisture in walnut kernel and bar denier wood benevolence is dried, and walnut kernel and bar denier wood benevolence are toasted out fragrance by hot stage, For example, can walnut kernel, bar denier wood benevolence, hazelnut kernel and a cashew nut kernel be baked to medium rare, toasted nut kernel and be ground again Slurry helps to enhance the taste flavor of nut beverage.

Specific embodiment
The present invention is further described below with reference to specific embodiment.
Embodiment 1
Nut composite beverage refining process in the present embodiment, comprises the following steps:
S1, premix:In percentage by weight, 83 parts of part, bar denier wood benevolence of walnut kernel, 2 parts of hazelnut kernel and cashew nut kernel 1 are taken Part, above-mentioned four kinds of nut kernels are pre-mixed uniformly;
S2, corase grinding:It is roughly ground using level-one stone mill, nut kernel is worn into nut slurry;
S3, fine grinding:It is refined using two level colloid mill, the nut slurry for roughly grinding preparation is worn into the heavily fortified point that fineness is 150 mesh Pulp;
The uniform micronization processes of S4, slurries:Three extruding two pairs of rollers is set to starch nut prepared by the fine grinding of two level colloid mill to carry out Uniformly grinding makes the fineness that nut is starched reach 200 mesh.
Low temperature environment is pursued in the process of nut kernel defibrination process, this is because temperature is higher, more be easy to cause nut slurry Oxidation of Fat and Oils in liquid.The applicant compares by the field adjustable of several months, finds existing refining process there are some not Foot, it is specific as follows:(1) stone mill defibrination is less efficient, and particle sice in serosity is uneven, and the mouthfeel for causing beverage is poor, consumer's drink There is granular sensation in used time;(2) for stone mill defibrination, colloid mill defibrination it is efficient, particle is thinner, the fineness of slurries Height, but the heat generated during this is very high, easily causes the unsaturated fat acid oxidase in nut kernel, the applicant The 5kg nut kernel materials formed according to said ratio are placed on defibrination in colloid mill, temperature rises to 80 DEG C after defibrination 10min, Up to 90 DEG C or more, this temperature is enough to make not including fatty acid oxidation the maximum temperature of defibrination process;(3) either stone mill is also It is colloid mill, they are all only applicable to the high nut category of the fat contents such as walnut kernel, and for the low nut product of fat content Class, for example, bar denier wood benevolence, then not easy-to-use stone mill or colloid mill defibrination, this is because bar denier wood kernel oil content is low and fiber Content is high, and to fiber is smashed, then frictional heat is more during defibrination, and it is excessively high in turn result in temperature, causes grease oxygen Change.
The nut composite benevolence mixed in proportion is passed sequentially through level-one stone mill, two level colloid mill and extruding pair by this programme Roller classification defibrination refinement slurries, overcome the deficiency of above-mentioned refining process, level-one stone are first used to nut composite in this programme Mill corase grinding has the advantages that following three by the way of the fine grinding of two level colloid mill again:(1) nut kernel is worn into the process of slurries In, the frictional heat amount between mill and nut kernel causes temperature to raise, and compared with by the way of colloid mill corase grinding, uses During stone mill is roughly ground, the temperature of mill will not be raised significantly, thus the problem of be not likely to produce high-temperature oxydation grease;(2) Usually nut slurries are beaten during defibrination more broken, the heat of release is more, and temperature is higher, in turn results in nut slurries Grease aoxidized, nutrition is caused to lose, thus this programme is first using corase grinding, during reducing defibrination to a certain extent The heat of release helps avoid grease and is aoxidized;(3) grease that the nut of high fat content discharges during defibrination promotees Into the lubrication between mill and nut kernel, thus nut composite is first premixed and uniformly roughly ground again, helps to balance nut composite Fat content in material so that defibrination process is more smooth, when solving in the prior art to the independent defibrination of each category nut kernel Since fat content is low, fiber content is high in nut kernel frictional force between mill and nut kernel is caused to discharge substantial amounts of heat greatly The problem of.In addition, when nut slurries prepared by level-one stone mill corase grinding enter back into two level colloid mill, there is good fluidity, charging surely The characteristics of determining, and at this time colloid mill again to certain fineness slurries refine when, the heat of release is also less, is not easy to It is aoxidized into the grease in nut slurries.Furthermore we have found the prior art directly using mill defibrination by Experimental Comparison In technique, still with the presence of larger particles in prepared nut slurries, the mouthfeel of consumer is affected, for this purpose, this programme exists Extruding two pairs of rollers is set fully to squeeze nut kernel particle present in fine grinding rear slurry after the fine grinding of two level colloid mill, are avoided With the presence of bulky grain so that evenly, the slurries of preparation are finer and smoother for the granularity of nut kernel particle, and fineness is the nut of 200 mesh Slurry ensures to improve the mouthfeel of nut beverage when consumer drinks without granular sensation.
