What does a Votator do?
For the meat industry, the Votator is used to cool deboned chicken emulsions, to heat sausage blends, and to cool offal from packing houses for use in pet food.
What are the advantages of a scraped surface?
Scraped surface crystallizers are cost-effective for larger installations where vacuum crystallization may seem attractive. The design minimizes shear stress on delicate crystals but is rugged enough to handle tough crystals.
What is a Thermutator?
The Thermutator® is used to heat or cool products that cannot be continuously processed by other type of heat exchangers. Products that would be used with this application: heat sensitive, film forming, highly viscous, have a particle size or delicacy that cannot be accommodated by other heat exchangers.
How does a scraped surface heat exchanger work?
In the scraped surface heat exchanger, spring loaded rotating blades scrape the surface and effectively remove liquid from it. Alternatively, the blades move against the heat transfer surface under the influence of the rotational forces.
What is scraped surface exchanger?
Scraped Surface Heat Exchangers (SSHE) are designed to overcome process problems encountered when processing viscous fluids. SSHEs incorporate internal mechanisms that remove products from the heat transfer wall. The inner pipe is scraped by blades that are attached to an axially central rotating shaft.
What is scraped surface crystallizer?
A scraped surface crystallizer consists of a jacketed pipe in which a cooling medium between the pipe wall and the jacket remove heat from the slurry, causing crystallization. Inside the pipe, large scrapers wipe the solid deposits from the wall to prevent build up.
What is tubular heat exchanger?
A tubular heat exchanger (THE) is used to warm or cool a product by exchanging heat between the process fluid and a service fluid, which is typically water, ice water, glycol or steam. The hot or cold service fluid flows around the tubes within the THE and heat is transferred between the product and the media.
How does a spiral heat exchanger work?
In a spiral heat exchanger, each fluid flows through a single channel. If suspended solids settle on the heat transfer surface, the increased fluid velocity creates a scrubbing effect that removes the deposits. At the same time, the cold fluid enters at the periphery and spirals inward, exiting at the center.
How does a double pipe heat exchanger work?
The double pipe heat exchanger works via conduction, where the heat from one flow is transferred through the inner pipe wall, which is made of a conductive material such as steel or aluminum. The double pipe heat exchanger is often used in counterflow, where its fluids move in opposite directions (as shown above).
Which industry uses crystallizer?
Crystallization is one of the most widely used technologies in chemical industry, and process robustness governs process productivity and economics. In particular, the pharmaceutical and food sectors are utilizing crystallization for optimized separation, purification, and solid form selection.
What is continuous crystallizer?
Continuous crystallization is a unit operation in which the mother liquid is continuously flowed in, and the slurry is continuously withdrawn. According to an analysis by Schaber et al. [10], the continuous crystallization process can save 9% to 40% of the production cost.
What do 1/2 heat exchangers mean?
Most shell-and-tube heat exchangers are either 1, 2, or 4 pass designs on the tube side. This refers to the number of times the fluid in the tubes passes through the fluid in the shell. In a single pass heat exchanger, the fluid goes in one end of each tube and out the other.
What is the votator process?
The “Votator process” for making these kinds of products allows for rapid cooling of the molten fat in the Votator scraped surface heat exchanger, so that many, tiny crystals are formed. Nitrogen gas can be injected along with the molten fat, to be whipped in under pressure and in a closed system.
Why choose votator® scraped surface heat exchangers?
For more than 80 years, Votator ® scraped surface heat exchangers have been replacing slow, inefficient batching operations with more uniform, controllable and repeatable continuous processing. The Votator ® II incorporates the most popular features of the Thermutator ® and Votator ® lines, making it extremely easy to maintain.
What is a votator used for in meat industry?
For the meat industry, the Votator is used to cool deboned chicken emulsions, to heat sausage blends, and to cool offal from packing houses for use in pet food.
Who makes the Vogt instant freezer?
This company became the Votator Division of Girdler Corporation in 1931, and Clarence Vogt was its first Vice President. The Vogt Instant Freezer and the Votator are both based on a similar construction.
