KELSTREAM SCRAPED SURFACE HEAT EXCHANGER

INOX is the expert processing partner and distributor for Kelstream scraped surface heat exchangers for inline cooling or heating of your product. Our territory covers Australia, Malaysia, Thailand and Myanmar. The Kelstream SSHE is commonly utilized in the aseptic processing of foodstuffs. These heat exchangers are preferred because of their capability to process heat-sensitive, viscous, or particulate-laden products, enhance the heat transfer of viscous products, and minimize the extent of burn-on, or fouling on the heat transfer surface. We bring together the know-how of our specialists and your specific preferences. Only then can it be the infallible link in your demanding production process.

Providing Australia And Asia Food Manufacturing Processors With Leading Edge Technology In Batch And Continuous Cooking Flexibility

The extremely versatile Kelstream Scraped Surface Heat Exchanger can be used for all thin, medium and high viscous products. These can be heated and cooled inline in a controlled way.

Choose your market for more specific information about the possibilities for your product:

	Feed – From animal feed (including cat and dog food) and fish feed to (poultry) fodder
	Food – From dairy and fruit to sweets and potatoes
	Pharmaceutical – From creams and Vaseline. All in a controlled environment
	Non-Food – From petrochemical uses to personal care

Processes

	Cooling Bringing down the temperature of your product as much as your process is asking for. Cooling can be done with several cooling mediums, like glycol and (ice) water.
	Heating Heating your product can be done by using steam to heat the surfaces. We can calculate how much steam you need to achieve the desired temperature.
	Tempering Tempering is a method of increasing the shine and durability of chocolate couverture by melting it and cool it down. WIth the Kelstream Scraped Surface Heat Exchanger you can temper chocolate in a very controlled way.
	Jellification Jellification is defined as the process of turning a substance into a gelatinous form. With this process, liquid substances are converted into solids with the help of a gelling agent.
	Crystallisation Crystallisation is the formation of solid crystals from a solution. Crystallisation is applied in the sugar and dairy industry, but also for crystallize Sodium Kelstream is applied.
	Pasteurisation Pasteurisation is a temperature treatment of food whereby microbiological organisms are destroyed in order to make the product safe for human consumption and to provide biological stability of the food product to improve its shelf life.
	Sterilisation Sterilisation is the removal of living micro-organisms, and can be achieved by using steam to heat the product. Steralisation is a heat treatment of over 100°C for a period long enough to lead to a stable product shelf-life.
	Boiling Boiling is heating the product till it reaches boiling temperature. Kelstream is able to calculate the amount of heat is needed to reach boiling temperature.

Benefits & Advantages

The Kelstream Scraped Surface Heat Exchanger has numerous advantages compared to other heat exchangers:

Efficient heat transfer due to two heated surfaces
High product flow up to a capacity of 10.000Ltr/h per unit
Low Downtime thanks to open-source maintenance
Highest quality for the right price

The Kelstream Scraped Surface Heat Exchanger has a huge variety of uses and processes. This is due to its economical and efficient design that fully serves its contents. An overview of the main properties:

The scraping principle: economical and clean
The mixing system continuously scrapes the whole heated or cooled surface, resulting in an extremely efficient transfer of heat. This scraping principle has a major efficiency advantage compared to a conventional plate or tube-shaped heat exchangers. Furthermore, this prevents the product from sticking to the side.

Mixing with preservation of homogeneity
An additional advantage of the mixing system is that the liquid also mixes while scraping. This promotes heat transfer and keeps the liquid homogenous. In some cases it is even possible to aerate the product, with or without compressed air or nitrogen.

Cooling/heating products with firm components
With the Kelstream Scraped Surface Heat Exchanger you can cool and heat products that contain firm components. The maximum product identity is preserved. You can cool/heat products with particles of a maximum size of 25 mm.

Thorough cleaning
The Kelstream Scraped Surface Heat Exchanger can be fully included in the existing CIP system. You can clean the Kelstream with or against the stream, whereby the mixing system can turn clockwise or anticlockwise. This results in optimum cleaning of the Kelstream Scraped Surface Heat Exchanger.

Low downtime
The Kelstream has open-source maintenance, which means it isn’t necessary to order spare parts from Kelstream. This can save a considerable amount of downtime during servicing or replacement. The Kelstream is also easy to use because the wearing part can be inspected via the hinged lid. It is not necessary to disassemble the shaft seal and bearings first. This easy way of inspection can prevent loss of time.

Constant capacity and temperature
The Kelstream is equipped with two covers through which a cooling/warming medium is pumped. Your product will be monitored and evenly warmed or cooled on two sides (inside and outside the cover). The cooling/ warming medium is completely isolated from your product.

Features & Principles

Kelstream’s Scraped Surface Heat Exchanger
The Kelstream Scraped Surface Heat Exchanger (SSHE) is commonly utilized in the aseptic processing of foodstuffs. These heat exchangers are preferred because of their capability to process heat-sensitive, viscous, or particulate-laden products, enhance the heat transfer of viscous products, and minimize the extent of burn-on, or fouling on the heat transfer surface.

Models and Options
The Kelstream Scraped Surface Heat Exchanger is available in a range from 0.5 m² up to and including 7.0 m² for capacities ranging from 100 ltr/hr up to a capacity of 10.000 ltr/hr per unit. The three biggest advantages of the Kelstream Scraped Surface Heat Exchanger are:

Two concentric heat exchange surfaces to provide an efficient heat transfer
Efficient heat transfer by continuous scraping the entire surface
A large heating surface per unit on a small footprint (so, it is space and cost saving)

G: Optional CIP Connection

Efficient Heat Transfer for Food, Feed, Pharma and Non-Food
Due to its two concentric heated surfaces, its scraper principle and its large capacity per unit, the Kelstream Scraped Surface Heat Exchanger is the perfect solution for your thermal process. The scraping also takes care for a homogeneous mixing without damaging the product or the particles (up to 25 mm) in it.

Flexibility
The Flexibility of the Kelstream, by controlling the jacket surface temperatures, together with choosing the correct ancillary equipment, allows the customer to achieve a flexible processing system by which new product developments can be easily and quickly adapted to production and quickly to the consumer market.

Different Process Configurations

Parallel

This process configuration allows the product to simultaneously feed through 2 or more Kelstream units in parallel. This allows simple and substantial increases in production output rates. Perfect for the growing company.

Series

When your process demands heating and cooling. The Kelstream can be linked together in series to provide a continuous process that provides both heating and cooling inline or provide 2 steps of cooling to achieve a product with high Delta T (temperature difference from start to completion).
