Filtration Aid Powder Dispersion for Beer

 Powder Dispersion using Filtration aid 

Most beers, especially lagers, are filtered to remove yeast and other suspended solids. This reduces the storage time required for the natural clarification of beer, improving stability and shelf life. The most commonly used filter media (or filter media) is synthetic amorphous silica (silica), commonly referred to as diatomaceous earth, which is available under a variety of trade names.

Process

An aqueous suspension of powdered diatomaceous earth is prepared in a separate container before being fed to the filter. The solid content can be varied depending on the dosage required for each type of beer.

The general manufacturing process for diatomaceous earth production using a conventional stirrer is as follows:

• The container is filled with water.

• The stirrer arranged to generate a vortex starts.

• The powder is slowly fed into the vortex.

• Continue mixing to completely disperse the powder and keep the solids in suspension.

Problems

• Using a traditional stirrer can cause some problems. 

• Diatomaceous earth is very low density and can emit large amounts of dust.

• The powder is easy to float. Incorporating the powder into the water requires vigorous agitation, exacerbating the dust problem and increasing oxygenation. The rate of addition of powder should be carefully controlled to avoid lump formation.

• Aggregates need to break down to fine particle size to create a stable suspension. 

• The cleaning effect of the stirrer cannot do this 

• A long mixing time is required to complete the dispersion/suspension.

Solution

Wahal Flashblend can be used to significantly reduce processing time and improve product quality.

Stage 1:

Water is drawn from the reservoir by a centrifugal pump and sent to an in-line mixer via a venturi assembly. The high-speed flow through the venturi creates a vacuum in the chamber below the powder hopper. Water is returned to the container via a self-pumping in-line mixer.

Stage 2:

The powder is fed to a specially designed hopper. As soon as the water circulates, the powder supply valve opens. The powder is sucked into a Venturi tube, where the water and powder flow are immediately mixed and immediately sent to the inlet of the Inline High Shear Mixer.

Stage 3:

Liquids and solids are subjected to strong high shear forces at the work heads of in-line mixers. When the powder addition is complete, the bypass valve opens and the flush blend is in fast recirculation mode. The entire contents of the bottle pass through the flash blend in a short mixing cycle, ensuring rapid completion of hydration.

Benefits

Wahal Bead Mill machine has many advantages over traditional systems.

• Processing time is greatly reduced.

• The rapid uptake of large amounts of powder.

• Improved consistency and reproducibility.

• Controlled powder addition rate

• Requires minimal operator input.

• Minimized cleaning requirements LIQUID POWDER MIXER is designed for Cleaned In Place (CIP).

• Designed to facilitate automation and connection to process computers.

• Dust Emission Reduction Flashblend can also be integrated into a dust extraction system.

• The Powder Incorporation system can be custom-built to meet the requirements of individual customers.

• Can be integrated into powder administration systems such as large bags (flexible containers). 

• The optional Funnel Flow Aid can be used on difficult powders.

Soft Drink Manufacturer : Sugar Syrups - Liquid Powder Mixer

 Soft Drink Manufacturer - Preparation of Sugar Syrups

The sugar content of carbonated and still soft drinks varies depending on whether the product is delivered ready for consumption, or as a concentrate (commonly referred to as “syrup”). Common formulas may contain concentrated spice or fruit juice, acidity controls, preservatives, solvents, antioxidants, and pigments. By “Food,” and other “sugar-free” sugary drinks are replaced by sweeteners such as Aspartame.

The process

One of the first stages in the normal production process is to prepare sugar syrup. Sugar is used in granulated or liquid form. Liquid sugar simply needs to be mixed with water, but when granulated sugar is used, many aspects of the processing must be considered:

Small-scale production of low-sugar syrups may be done at ambient temperature. However, with certain concentrated products, 60% or more sugar solutions are rare, requiring hot water to help dissolve.

For large operations, temperatures of up to 95 ℉ (35 ℃) may be generated to accelerate melting.

Some powdered ingredients may be dry mixed with half the sugar, which helps prevent the mixing and "weight" of the simple powder that often floats.

The problem

1. Liquid sugar may be more expensive than granulated sugar.

2. The melting of powdered sugar with a simple movement is a slow process.

3. Ordinary agitators are unable to dissolve high sugar levels at local temperatures.

4. Heating water for convenience adds to the cost and does not save energy.

5. The cooling process also adds to the cost and processing time.

6. Crystallization of syrup may occur during heating/cooling.

7. Incomplete solubilization may lead to loosening or even blockage of vessels.

Solution

The Wahal Engineer High Shear Mixer may significantly reduce mixing times and eliminate the need for water heating. This may be achieved with Batch Mixers in the tank or by adding a Wahal Engineer In-Line Mixer to the existing system. This works as follows:

Stage 1

The high-speed rotation of the rotor blades creates a strong absorption of water and sugar granules on the vessel to the work surface.

Stage 2

Centrifugal force drives objects into the work area around the head when they are under the grinding action in the space between the rotor and the stator wall.

Stage 3

The product is forced out of the stator as new materials enter the subject matter. In a short mixing cycle, all substances pass over the work head, gradually reducing the particle size and exposing the growing area of ​​sugar to the surrounding liquid, speeding up the dissolution process.

Benefits

1. The combination of reducing granule size and strong mixing significantly reduces mixing times.

2. 66% sugar syrup may be produced at ambient temperature. 

3. Various flexibility allows the manufacturer to use sugar in the form of granulated or syrup.

4. The Wahal Engineer mixer may also disassemble and apply water solubility and stabilizing agents such as CMC and Xanthan gum in part of the time taken by other means.

There are several products in the Wahal Engineer range that are suitable for this application, their selection is determined by the requirements of each process including the size of the collection.

Soft Drinks Formation

 Soft Drinks Formation - Dispersal / Watering of Active Ingredients

Ingredients such as gums, starch, alginates, etc. are found in many soft drinks that include fruit juices, squashes, sweetened milk, and carbonated beverages. These "active" ingredients make up a very small percentage of the total composition, but include important features:

1. Hardness: Allowing the formula maker to obtain viscosity and texture (known as “mouthfeel”). Especially important is the low calorie or sugar-free products where the effect of sugar filling should be reversed. Many different products are used, including xanthan gum, pectin, etc.

2. Stabilization: Keeping particles (eg fruit pulp) suspended. Several products are used e.g. CMC, starch, propylene glycol alginates (PGA), pectin, and gums such as guar and gum arabic. Carrageenan is used to stabilize cork in milk drinks. Many of these ingredients will provide firming and strengthening effects.

The process

Depending on the degree of production, the solids/solids may be dispersed directly into the batch, or different premises may be prepared for use in different products. In any case, to get the performance of these products, they must be properly dispersed and watered. Many procedural requirements must be met to achieve the following:

1. The powder/liquid mixing system should be able to mix the powder and disperse it into all the contents of the mixture.

2. The powders should be thoroughly soaked in water to increase yields.

3. Some products are “activated” unless the particles are “individually owned.”

4. A high level of shear is sometimes required for other products to work and be fully hydrated.

5. Some types of ingredients require heat to absorb water.

The problem

Hydration of gums and thickeners is one of the most difficult tasks to assemble. If you use standard agitators, many problems can arise:

1. The powder should be added at a controlled rate to reduce the formation of lumps.

2. Conventional agitation systems do not produce enough cuts to break down agglomerates.

3. Mixing powders, (usually with sugar) is often done to reduce agglomeration; this increases costs and time.

4. When active ingredients are prepared, the viscosity increases, making mixing more difficult.

5. Prolonged processing time may be required for proper dispersion of powders and complete hydration.

6. Incomplete hydration also reduces the production of immature substances.

7. Many forms contain unnecessarily high levels of these materials to compensate for poor yields and processing efficiency.

Solution

The Wahal Engineer High Shear mixer can overcome these problems. Benefits from the three-stage action mixer / Wahal Engineer rotor/stator mixer. Performance is as follows:

Stage 1

The vessel is charged with water and the mixture is started. The powder is added and immediately immersed in water. The high-speed rotation of the rotor blades creates a strong absorption that pulls the liquid and powder ingredients into the work surface.

Stage 2

The particles are agglomerated in the space between the rotor and the stator. The product is forced out of the stator and produced brilliantly back into the body of the mixture as new ingredients are extracted from the active ingredient. All the powder is quickly absorbed and dispersed.

Stage 3

In a short mixing cycle, all substances pass over the work head, gradually reducing the particle size and exposing the growing area to the surrounding fluid, speeding up the hydration process.

Benefits

1. Amazing reduction in mixing times.

2. Agglomerate-free mix.

3. Dry premixing is not required.

4. High yield.

5. Ability to start or stop the process quickly to process ingredients when needed.

6. Stable product quality and duplication.

7. Improved shipping.
