A high-activation granular coal carbon for the purification of alcohol after distillation.

Product Description and Function

Activated Carbon is an ultra high purity, highly effective, steam activated granular coal carbon with optimum performance for a wide range of purification applications including the purification of alcohol after distillation.

This product has an internal structure with a pore-size distribution optimised for adsorption of small molecular weight congener impurities that contribute to off-flavours and off-aromas in distilled alcohol.

Activated Carbon has a high absorptive capacity due to its high inner surface area. The 20×40 mesh granular particle size of this carbon minimises dust generation on handling.

Technical Characteristics

Particle size: 20×40 mesh (0.425—0.85 mm)
Iodine number: > 1000 mg/g
Methylene blue number: 280 mg/g
Apparent density: 480 kg/m³
Surface area: 1050 m²/g
Total pore volume: 1.04 cm³/g
Moisture content: <5%
Total ash content: <13%
Water soluble ash: 0.2%
Hardness: >95
Wettability: >95
pH: 8-11

Dosage and Application

Activated Carbon should be packed into a bed ideally with a minimum height of two metres. The bed diameter should ideally be 350mm for a 2m height to maintain optimum ratio of 6:1 height to diameter.

Flush the packed carbon bed with hot water and allow to drain before passing alcohol through it using gravity. For optimum performance it is essential to dilute alcohol to 50% volume/volume prior to treatment.

Flow rate of alcohol through column can be restricted to achieve optimum contact time for required level of purification if necessary.

A premium granulated sodium-calcium bentonite for use as a fining agent in alcoholic beverages.

Product Description and Function

Sodium bentonite is a premium quality, beverage grade, sodium-calcium bentonite clay in an easy to handle and disbursable granulated form. This high montmorillonite bentonite clay can be used for protein stabilisation and clarification in production of wines, ciders, and fruit juice.

Treatment with bentonite will remove excess tannins and unwanted colloidal proteins which cause off-flavours and turbidity issues in the finished beverage. When used in conjunction with other fining agents, bentonite will also improve the rate of clarification.

Technical Characteristics

Appearance: Off-white granules
Moisture content: 8% max.
pH (5% sol.): 8.5-10.0
Montmorillonite content: 80% min.
Swelling rate—water: 5-6 ml/g
Swelling rate—wine: 3-4 ml/g

Soluble matter in 1% tartaric acid solution:
Sodium: <0.5%
Calcium: <0.4%
Iron: <0.05%
Lead: <20 ppm
Arsenic: <2 ppm

Dosage and Application

Bentonite can be added directly to the juice or must, but for greater efficiency it is recommended to suspend in water (or a volume of juice/must) prior to addition. Bentonite can be removed by filtration or decanting after several hours, but for maximum effect in fermentation application, leave in contact with media throughout the entire fermentation process.

To prepare a suspension, add bentonite to 10x weight of cold water/juice/must under constant stirring and leave to stand for 30-60 minutes. After 30-60 minutes, stir again and leave to stand for a further 6-12 hours, stirring occasionally to allow the bentonite to swell. After 6-12 hours, decant any excess water and add the remaining slurry to the medium to be treated. Once added, mix the medium thoroughly in order to fully distribute the bentonite.

Dosage will differ depending upon application and level of treatment required.

A highly effective liquid fining agent for the clarification of alcoholic beverages.

Product Description and Function

SPL Chitosan is a high purity solution of chitosan flake β-1,4-poly-D-glucosamine—derived from the shells of Crustacea—for use as a high performance clarification agent or flocculation aid in alcoholic beverages applications.

The macromolecular structure of chitosan combined with strong positive charging ensures rapid interaction with negatively charged yeast cells and other fermentation debris, producing a strong and rapid flocculating action and forming compact lees.

For optimum clarification results, SPL Chitosan should be used in conjunction with a suitable colloidal silica solution / silicic acid such as SPL Kieselsol.

Technical Characteristics

Appearance: Colourless to pale yellow viscous liquid.
Density: 1.0g/ml (+/- 0.02)
pH: 2.6 (+/- 0.2)
Heavy metals (as Pb): <10ppm
Lead: <5ppm
Arsenic: <1ppm
S0₂: <500ppm

Dosage and Application

For use as a clarification agent:

Chitosan can be applied directly to the beverage once fermentation is complete and the beverage has been stabilised / preserved (if necessary). Before using Chitosan it is preferable to degas the beverage as excess dissolved CO₂ will increase the clarification time.

Chitosan can be introduced directly into the fermentation or clarification vessel at a rate of 400g/hl. Once added, the beverage should be agitated gently to ensure thorough distribution and left to clear before racking off from the lees. Dosage can be optimised based on specific application / requirements.

For optimum clarification speed and lowest post clarification turbidity SPL Kieselsol should be added 1 hour prior to addition of SPL Chitosan.

For use as a flocculation aid:

Where using SPL Chitosan as a flocculation aid, add to beverage at the end of fermentation at a rate of 200g/hl and leave to flocculate for between 6—12 hours before centrifuging and filtration.

A highly effective silica sol fining aid for use in the clarification of alcoholic beverages.

Product Description and Function

SPL Kieselsol is an aqueous solution of colloidal silica for use as a high performance fining aid in the clarification of fermented alcoholic beverages. SPL Kieselsol is suitable for use with a wide range of fermented alcoholic beverages as it can be used across a wide acidity and pH range.

SPL Kieselsol has been specially developed for beverage fining applications, with optimum charging and alkalinity ensuring rapid interaction with yeast cells and other debris. The colloidal silicic acid particles in SPL Kieselsol are unagglomerated prior to use meaning that the material has a low viscosity—this combined with the optimum particle size distribution, ensures that the colloidal content does not settle out during storage.

SPL Kieselsol must always be used in conjunction with a positively charged fining agent such as chitosan or gelatine. Addition of Kieselsol alone will not clarify the beverage. Kieselsol has a strong negative charge and will significantly improve clarification performance of chitosan or gelatine due to opposite charging forming a strong interaction.

Technical Characteristics

Appearance: Opalescent turbid liquid.
Density: 1.2g/ml (+/- 0.02)
Total solids: 30% (+/- 1)
Na2O content: <0.3%
pH (at 20C): 10 (+/- 0.5)
Specific surface area (sears): 200 m²/g (+/- 20)
Iron: <150 ppm
Titanium: <200 ppm
Arsenic: <1 ppm
Lead: <1 ppm

Dosage and Application

SPL Kieselsol can be applied directly to the beverage once fermentation is complete and the beverage has been stabilised / pre-served (if necessary). Before addition of Kieselsol and other fining agents it is important to thoroughly degas the beverage as excess dissolved CO₂ will increase the clarification time.

For application, Kieselsol can be introduced directly into the fermentation or clarification vessel, or can be applied using a pump, at a rate of 60g/hl. Once added, the beverage should be agitated to ensure thorough distribution and left to stand for 1hr before addition of chitosan or gelatine.
