For many years, we have been raising productivity, lowering production costs, and delivering Scraped Surface Heat Exchangers products with affordable price and excellent quality for a wide range of processing industries. With SSHEs, companies in the food, chemical, petroleum, pharmaceutical, and allied industries have reduced labor costs and increased production efficiency.
SSHEs continue to replace many slow, inefﬁcient batching operations with more uniform, controllable, and repeatable continuous processing.
SSHEs’ superior heat transfer performance and ability to handle a wide range of viscosities makes it the clear choices over tubular or massive plate heat exchangers in viscous applications.
Standard SSHE is a new type of scraped surface heat exchanger that can be used to heat and cool products of various viscosities, especially suitable for extremely viscous and viscous products. It has strong quality, economical hygiene, high heat transfer efficiency, and affordable features.

Heat Sensitive Products– Products which are degraded by prolonged exposure to heat are effectively processed in Ftherm® X Scraped Surface Heat Exchangers. The scraper blades prevent product from remaining on the heat transfer surface by continuously removing and renewing the ﬁlm. Because only a small amount of product is exposed to heat for just a short time, burn-on is minimized or eliminated.
Viscous Products– Ftherm® X Scraped Surface Heat Exchangers process viscous products far more efﬁciently than conventional plate or tubular heat exchangers. Product ﬁlm is continually scraped from the heat transfer wall to induce high heat transfer rates; constant agitation causes turbulent ﬂow and more consistent heating or cooling; pressure drop is effectively controlled by the product annulus area; agitation eliminates stagnant areas and product build-up; and cleaning is easier.
Particulate-Laden Products– Products with particulates which tend to plug conventional heat exchangers are handled easily in Ftherm® X Scraped Surface Heat Exchangers, and the particulates maintain maximum product identify.
Crystallized Product– Products which crystallize are ideal candidates for Ftherm® X Scraped Surface Heat Exchanger processing. As product crystallizes on the heat transfer wall, the scraper blades remove it and keep the surface clean.
Chemical Processing– The chemical, pharmaceutical, and petrochemical industries can employ Ftherm® X general categories.
1. Heating and Cooling: Processing very viscous materials is not a problem for the Ftherm® X Scraped Surface Heat Exchanger. The product ﬁlm is scraped from the hot or cold tube surface many times a minute, preventing a fouled or frozen layer from forming to block further heat transfer. The total product ﬂow area is generous, so pressure drop is minimized.
2. Crystallization: The Ftherm® X Heat Exchanger can be used as a sidearm cooler, cooling a batch tank to the saturation temperature where solutes begin to crystallize. Recirculating through the heat exchanger at a high ﬂow rate produces seed crystals that grow large enough to separate after the ﬁnal temperature is reached. Waxes and other products that completely solidify can be cooled almost to the melting point in a one-pass operation, then ﬁlled into molds, deposited on cold belts, or pelletized using additional equipment.
3. Reaction Control: Chemical reactions can be driven by the controlled addition of heat using a Ftherm® X Heat Exchanger. For exothermic reactions, the heat exchanger removes the heat of reaction to prevent degradation of the product or unwanted side reactions. The heat exchanger can be operated at pressures up to 870 psig (6MPa).
4. Any of the Above with Aeration or Mixing: The Ftherm® X Heat Exchanger delivers intense mixing to the product as it ﬂows along the rotating shaft, so that a gas can be incorporated into a product at the same time that it is heated or cooled. A foamed material can be manufactured by addition of gas, rather than by relying on a chemical reaction to generate the gas bubbles as a by-product. The mixing action also promotes uniform distribution of crystals in a matrix or improves reaction kinetics by intimately mixing the reactants.
Scraped Surface Heat Exchanger components are manufactured in a variety of conﬁgurations and materials so that each unit can be assembled to meet the speciﬁc processing requirement of each application. All pressure elements are designed in accordance with GMP，CFIA，3A or ASME code requirements and can be FDA certiﬁed.
