Abstract

The present invention relates to a special-purpose filter aid using pearlite as main ingredient (by dosage) for beer. Said filter aid is composed of three kinds of raw material of expanded pearlite (4-8 weight units), roasted protein earth (0.5-2 weight units) and raw protein earth (2-4 weight units). According to the different requirements for filtration, their dosages can be flexibly regulated. Said filter aid is mainly used for adsorbing and removing inutile micro particles produced in the course of production of beer.

Description

Composite pearlstone filter aid for beer

When the present invention relates to a kind of beer production and filtering, inherent part particulate and pigment in the absorption beer make product color light bright, but the flocculating aids of not a slip of tongue sense local flavor.

Traditional beer production flocculating aids, the general natural diatomaceous earth that adopts through roasting, before beer filtration, dope beer, its surface adsorption ability of mat, unwanted inherent part particulate and pigment in the beer, be adsorbed onto the surface selectively, be filtered together with the wine dregs of rice at last, along with China's beer production surge, high-quality diatomite lacks, people such as Li Ning once introduced beer filtration quite effective (Chinese patent publication number CN1083739A) to geographic light shale ore deposits, Xing'an Mountains " opoka " composite multipurpose flocculating aids, but from production reality distance were arranged still.

Whether beer quality improves grade, and flocculating aids is conclusive last pass, and particles contained and pigment adsorbs not enough as if flocculating aids, the cocktail party dulling, and mouthfeel is heavy, but absorption is excessive, and wine and women-sensual pursuits is pale, loses its relish.

The object of the present invention is to provide a kind of special-purpose flocculating aids of actual compound pearlite beer that is applied to produce, its physicals meets traditional mode of production and requires (with reference to diatomite), the beer finished product quality GB2758-81 that is up to state standards.

Purpose of the present invention realizes being to have strengthened perlitic consumption, it is expanded to original volume is pulverized more than 15 times, because its surface adsorption poor-performing, carrier mainly as recombiner uses, make this agent physicals meet production requirement, the absorption property of recombiner mainly relies on absorption property to be better than diatomaceous opoka, therefore from the two component composite filter aids (both weight unit ratio be 8: 6) of consumption unit's ratio, can carry out the scale production of beer by former diatomaceous filtration process based on pearlstone.Opoka can increase its adsorptivity after through 600 ℃ of left and right sides temperature roastings, with roasting raw material weight collocation not than being 1: 2.

Characteristics of the present invention are that prescription is simple, adjust and filter smoothness (pearlstone consumption), and adsorptivity physical indexs such as (giving birth to ripe opoka consumption) is easy, and by the beer production requirement of different manufacturers, the workman is not difficult to grasp.

The embodiment of the invention is as follows:

Be crushed between 120～140 orders standby after being expanded to the perlite ore heating more than 15 times earlier, in addition with opoka in converter with roasting between 550～650 ℃ 2～3 hours, cooling is come out of the stove and is become grog and be crushed between 100～150 orders, again opoka raw material (not roasting) are crushed between 100～120 orders, select certain proportion evenly mixed by the beer filtration requirement of different manufacturers above three kinds of materials, the special-purpose flocculating aids of beer, its proportioning setting range is as follows:

4～8 weight unit of pearlstone

0.5～2 weight unit of opoka grog

2～4 weight unit of opoka raw material

Because high adsorption capacity can reduce 35% than former diatomite consumption, therefore improve beer through the actual use of brewery Filter smoothness and reach 40%, product detects and meets beer standard GB/T 2758-81 fully. Color and luster is light bright simultaneously, mouthful Feel, the harmful substances such as fluorine, cyanogen, arsenic, mercury, nitrite absorption elimination factor is reached more than 90%.

Claims

1. the special-purpose flocculating aids of compound pearlite beer is characterized in that filtering smoothness based on pearlstone (pressing consumption) in order to adjust, and is the mixture of main sorbent material with the autochthonal grog of albumen.

2. according to the special-purpose flocculating aids of the described beer of claim 1, it is characterized in that: the pearlstone turgidity is more than 15 times, between granularity 120～140 orders.

3. according to the special-purpose flocculating aids of the described beer of claim 1, it is characterized in that: 580～650 ℃ of opoka maturing temperatures, 2～3 hours time is between granularity 100～150 orders.

4. according to the special-purpose flocculating aids of the described beer of claim 1, it is characterized in that: between raw material (not roasting) opoka granularity 100～150 orders.

5. according to the special-purpose flocculating aids of the described beer of claim 1, it is characterized in that: pearlstone, grog (through roasting) opoka, raw material opoka three mixed weight unit setting range is followed successively by 4～8, and 0.5～2,2～4.
