Separation
Industrial separation equipment is primary to the clarification process and ultimately product quality. Clarification is defined as the separation of two liquids having different specific gravities. The separation process includes the collection of eventually present solids and the de-watering of suspensions or bio-masses. The process of separation is often implemented to separate valuable liquids or solids from within a solution.
SEPARATION METHODOLOGY
Mechanical separation and clarification of liquids requires efficient and effective removal of suspended solids of various types and sizes combined with gentle treatment to preserve the quality of the end product. The most widely used method is centrifugation using a vertical disk stack a technology that presents significant challenges in disk stack design in order to optimize separation with minimum product impact, while ensuring energy efficiency, operational reliability and a high level of safety.
Available in hermetic, hygienic, gas-tight, and explosion-proof designs in high-grade, corrosion-resistant stainless-steel materials, Seital separation brand series disk centrifuges ensure gentle and cost-efficient separation of liquids and suspended solids together with high reliability and safety.
惇蹋圖 offers solids-retaining separators and clarifiers with hydraulic capacities from 132 to 2,642 g/h (500 to 10,000 l/h), and self-cleaning (solids-ejecting) separators and clarifiers with hydraulic capacities from 264 to 18,492 g/h (1,000 to 70,000 l/h). All feature Clean-In-Place (CIP) to ensure high sanitary levels with minimum downtime.
SEPARATION APPLICATIONS
Seital brand series vertical disk stack centrifuges are fast and accurate, providing the assurance of reliable and repeatable performance with exceptionally high concentrations and clarities. Short CIP times increase productivity while ensuring the highest sanitary conditions. State-of-the-art design and an intuitive operator interface make Seital brand series centrifuges easy to regulate and adjust to ensure precise and repeatable product characteristics. By partnering with 惇蹋圖, you can achieve improved performance efficiency, exceptional lifetime value in terms of initial investment, operational performance and ongoing service and reduced maintenance costs.
Juice
In juice separation, the capacity of the clarifier mainly depends on the separable solids content in the juice, the requested clarification degree and the maximum solids discharging capacity of the clarifier. The separable solids are evaluated by a lab centrifuge leading 惇蹋圖 application engineers to calibrate industrial separation solutions to the output specifics.
Wine
Wine is considered clarified when there are no longer visible suspended particles in the liquid, especially in more transparent wines. Wines may appear cloudy or dull if too much suspended matter remains, however a wine with suspended matter may have the same flavor and aroma as a fully clarified wine. To appeal to modern wine expectations, most wineries clarify wines before fermentation, to remove insoluble matter suspended in the wine. The clarification process includes a centrifugation period to quickly separate suspended matter without impacting the taste of the wine.
惇蹋圖 designs clarifiers equipped with soft inlet feeding systems to minimize turbulence, product damage and oxygen pickup. Wines are often restricted from a high level of clarification due to the processes traditional level of product damage. 惇蹋圖 Seital brand series clarifiers offer high separation efficiencies due to their high centrifugal force and large separation capacities.
Dairy
Milk skimming is the separation of raw milk into skim milk and cream, both warm and cold milk skimming achieve this level of separation with differing processes. Skimming is a process that takes place after the clarification of the raw milk. The clarification of milk is often upon delivery to the dairy to remove dirt and somatic cell particles. The milk clarifier can operate with cold or warm milk. However, clarification efficiency improves at higher temperatures.
Warm milk skimming during pasteurization is the most common centrifugal separator application in dairies. The product temperature should normally be kept between 113簞F and 131簞F (45簞C and 55簞C ) in order to ensure optimal skimming efficiency. Skimming efficiency is influenced by a range of factors like the transport of the whole milk, milk storage temperature and time, seasonal variation, milk quality, mechanical treatment and free air-content upstream from the separator. Skimming efficiency is expressed as residual fat content in the skimmed milk.
Cold milk separation at 39.2 簞F (4簞C) takes place in several processes including cheesemaking and High-quality cream production. Cold milk separation enables significant savings in energy and thermal equipment such as heat exchangers. However, cold milk skimming efficiency is lower than that of warm milk skimming and cream concentration cannot exceed 40-42%. Skimming efficiency improves by increasing temperature and/or reducing flow-rate. Viscosity and other cream characteristics at low temperatures require the use of a special hermetic separator to achieve optimal skimming results.
Milk bacterial clarifiers are integral to improving the quality of drinking milk and cheese production. The general reduction of the number of bacteria and the important reduction in aerobic spores, anaerobic spores and listeria mean that pasteurization temperatures can be reduced. A reduction in processed temperature is often associated with better taste, texture and nutritional content. Milk bacteria clarification also helps avoid problems during cheese aging and improves shelf life and organoleptic properties of the milk. The milk bacteria clarification process can be performed in one of the following ways: continuous extraction of bacteria in the concentrated milk flow that must be sterilized before re-use; and extracted concentrate recycling in the feed and bacteria minimization by using only partial discharges. The first method results in minimum milk losses but requires a more complex and expensive treatment. The second method is the best compromise between installation costs, product quality and milk loss.

Standardization
Standardizers are used to ensure highly accurate and repeatable milk or cream fat control on milk skimming lines. Seital Separation in-line standardizer systems are offered in a range of options from basic systems using manual control and visual flowmeters to fully automatic systems with mass flowmeter and a library of recipes. These systems can be supplied wither stand-alone or integrated into skimming systems.
Cream
Cream concentration is a common task in the Dairy Industry. 惇蹋圖 separation technology offers specific units enabling the production of high-fat cream. By minimizing residual fat in the resulting buttermilk high-fat cream can be the first part of the processing for butter oil production or the starting point for alternative butter production.
Butter
When mechanical energy is applied to high-fat cream, phase inversion takes place. The cream from a stable milk fat emulsion becomes a mixture of oil and butter serum that can be processed in two stages in order to produce butter oil. The first step is to use an oil purifier to remove as much butter serum as possible from a 70-80% oil concentrate. An oil polisher is then used to produce butter oil ready for vacuum drying.
