Abstract
The invention relates to an auxiliary preparation for processing cane sugar and particularly provides a natural quebracho tannin sugarcane juice clarifying aid and a preparation method thereof. The preparation method is characterized by adopting tannins (in a natural polyphenol structure (flavonoid substance)) extracted from quebracho core materials growing in the north of Argentina as raw materials for production, thus achieving the aim of reducing the amount of sulphur in a manufacturing process.
Description
Technical field
The present invention relates to a kind of auxiliary agent of sucrose processing, specifically provide the wooden tannin cane juice clarification of a kind of natural heavily fortified point auxiliary agent and preparation method thereof.
Background technology
Under the prior art, in utilizing the technological process of cane sugar manufacture, especially in syrup come-up clarifying process; Need to add the clarify and decolorize agent, traditional method is to add lime, sulphur or phosphoric acid etc., though this clarification aid use cost is low; But it is easy in sugar refining technology, stay toxic substance; And need frequent cleaning evaporating pot, after eliminating the interpolation clarification aid, the incrustation that in evaporating pot, stays.
Summary of the invention
The present invention is exactly to above problem; The wooden tannin cane juice clarification of a kind of natural heavily fortified point auxiliary agent and preparation method thereof is provided; It adopts the tannin that grows in the natural polyphenol structure of extracting in the northern hard reel material of Argentina (flavonoid material) as the raw material production product; Thereby reduce sulphur in the realization sugar refining technology, the purpose of lime consumption.
The technical scheme that the present invention adopted is following:
The wooden tannin cane juice clarification of a kind of natural heavily fortified point auxiliary agent, its chemical structural formula is:
The preparation method of the wooden tannin cane juice clarification of a kind of natural heavily fortified point auxiliary agent, it comprises following steps:
A, with the wooden tannin of natural heavily fortified point of 42 mass parts, the water of the monoethanolamine of 11 mass parts and 47 mass parts adds agitator tank and stirred 20 minutes, the temperature inside the box is controlled at 100 ℃-120 ℃;
B, mixing solutions added carry out chemical reaction in the reaction kettle, temperature control 35-38 ℃, reacted 9 hours.
The wooden tannin cane juice clarification of a kind of natural heavily fortified point of the present invention auxiliary agent is that the tannin with the natural polyphenol structure extracted in the hard reel material that is grown in Argentinian northeast is the product that main raw material is produced, and this tannin concentrates and forms through aqueous extraction, multiple-effect evaporator.
The wooden tannin cane juice clarification of a kind of natural heavily fortified point of the present invention auxiliary agent is that reddish-brown is liquid, and pH value is 2.3 ± 0.5, density 1.13-1.17g/cm
3, molecular weight is at 300-20000.
The wooden tannin cane juice clarification of a kind of natural heavily fortified point of the present invention auxiliary agent, it has following advantage:
1, reduces the consumption 13% of syrup enriching stage steam.
2, the cleaning interval that prolongs evaporating pot is usually at 6-9 days.
3, reduce the evaporating pot scavenging period.
4, increase steam flow rate and reached 40%.
5, the sulphite 15-20% in the reduction white sugar.
6, reduce the consumption 55-60% of cane juice clarification stage sulphur.(one-level white sugar, colour 100-150)
7, reduce the consumption 100% of cane juice clarification stage sulphur.(refining white sugar, colour≤60)
8, reduce lime consumption 20%.
9, reduce scale inhibitor and use 100%.
10, the sulphur content 75-80% in the reduction white sugar.
11, reduce duration of service 20% of washer/square.
12, improve the pH value 9.5% of plant steam in the concentration tank.
13, reduce amine usage quantity (being used for steam boiler handles) 85%.
14, reduce quicklime and the content of Natural manganese dioxide in subsider juice and reach 13%.
15, improve healthy protect and the environment protection in the operation, and reduced the quantity discharged of sulfurous gas in the atmosphere.
The wooden tannin cane juice clarification of a kind of natural heavily fortified point of the present invention auxiliary agent; Reduce the labor force through reducing or replacing the sulphur operator, improve energy saving through stopping the sulphur furnace runs, because the use that has reduced calcium sulfite and reduced lime; Dirt in the vaporizer is reduced; Thereby improve the heat effect and prolonged cleaning cycle, incrustation scale generation in the minimizing concentration tank and chemical products reduce the use of other assistant chemical products to corrosion on Equipment; Not only improved the quality of white sugar, and the depreciation that causes because of burn into wearing and tearing of reduction equipment.In the long-term quiescent period of equipment, reduce sugar and return look and color generation, even sugarcane juice is squeezed, still can keep its clean and bright in relatively poor equipment, reduce sulphite in the sugar greatly, be non-sugar.Simultaneously, extracting in the production of alcohol at syrup, can reduce glycerine and generate, improve the quality of ferment effect and alcohol, is the green plants polymkeric substance that is applicable to foodstuff production.
Embodiment
Below in conjunction with specific embodiment the wooden tannin cane juice clarification of a kind of natural heavily fortified point of the present invention auxiliary agent and preparation method thereof is done further to describe.
Embodiment 1:
The wooden tannin cane juice clarification of a kind of natural heavily fortified point auxiliary agent, its chemical structural formula is:
The wooden tannin cane juice clarification of the natural heavily fortified point auxiliary agent of present embodiment; It mainly is applicable to clearly the juice clarification stage, and clear juice is evacuated to the clarification aid of 80ppm in the setting tank by volume pump after the sulphur gas disposal; Add lime according to common program then, juice is transferred to suitable substance P H value (6.8-7.4).
The wooden tannin cane juice clarification of the natural heavily fortified point auxiliary agent of present embodiment, its inorganic and organic granular to colloidality has powerful solidifying/flocculating properties.React the generation insoluble complex with the predecessor of pigment.And metal there is very strong chelating property, especially iron and magnesium.And work, thereby obtain sterilization effect with the cell walls of polysaccharide bacterium.
Embodiment 2:
The preparation method of the wooden tannin cane juice clarification of a kind of natural heavily fortified point auxiliary agent, it comprises following steps:
A, with the wooden tannin of natural heavily fortified point of 42 mass parts, the water of the monoethanolamine of 11 mass parts and 47 mass parts adds agitator tank and stirred 20 minutes, the temperature inside the box is controlled at 100 ℃-120 ℃;
