The characteristic feature of food production is to need processed high viscosity product, and the concentrate, fruit juice, soup, dairy produce and other that for example are used for soda have the product of fluid concentrations.Nature, health in this case crave for be contemplated to be very high can satisfy the requirement of different government organs.
Heat-exchangers of the plate type is used for multiple different purposes in food service industry.The problem that use is used for the heat-exchangers of the plate type of food service industry is that some products comprise the fiber and other solid material of sneaking into fluid.In most heat-exchangerss of the plate type; Heat exchanger comprises one type plate; It is installed together two different passages that are formed for fluid with each other plate of Rotate 180 degree, and a passage is used for cooling medium, and another passage is used for product to be cooled.Between each plate, be provided with sealing.This layout is practiced thrift cost and effective to many application, but concerning the beverage that comprises fiber and other solid material etc., some defectives is just arranged, because plate can support at some contact points each other.Each plate is provided with ridge and ditch improves the heat exchange to liquid on the other hand on the one hand mechanical hardness to be provided.The local plate of joining at the pattern of plate will support each other, and this will improve the mechanical hardness of plate packing.The defective that plate supports each other is that each strong point can constitute the throttling part, and the material that in this liquid, comprises can be detained and gather.The further restricting flow of gathering of material meeting causes more material build.The formation of this similar a bit estuarine delta, its medium and small mobile difference can deposit some materials, and it causes more material deposition again.
The clogged with material problem solution is to use the contactless heat exchanger of product channels in heat-exchangers of the plate type.Such heat exchanger has reduced gathering of material in the product channels.
US4403652 has described the heat exchanger with contactless passage.This heat exchanger comprises the hot plate of certain compressed moulding, and hot plate has two sides that connected by web and the specific collector part of processing through casting.When plate is stacked when forming heat exchanger, obtained contactless passage.This scheme is quite expensive and complicated, but is effective to some application.
When use was used for the traditional heat exchanger plate of contactless heat-exchangers of the plate type, in order to obtain enough rigidity, plate forever combined through for example welding or soldering in couples.Like this, two plates form carton and crate, have a plurality of contact points between the plate, and wherein the edge junction of contact point and plate lumps together.Carton and crate is enough firm to deal with some pressure differentials between two kinds of fluids, guarantees contactless product channels thus.A kind of heat-exchangers of the plate type with contactless passage is shown in JP2001272194.In this heat exchanger, two plates with same type of cannelure forever combine and form carton and crate, and the vertical passage that wherein forms is used for heat-exchange fluid.It is stacked that this carton and crate uses packing ring to carry out, and between two carton and crates, forms contactless product channels thus.
WO2006/080874 discloses another kind of heat exchanger with contactless product channels.In this disclosed heat exchanger, use perpendicular to the wrinkle of flow direction and wave pattern plate provided rigidity and also to improve two kinds of heat transmission between the fluid.For this reason, need two kinds of dissimilar plates.Two plates of first type form first carton and crate, and two plates of second type form second carton and crate.The pattern of plate makes and when two carton and crates put together, forms product channels that wherein plate does not support each other.According to the size of heat exchanger, the distance between the plate in the contactless product channels can be in the 2-12mm scope.Such heat exchanger has reduced gathering of at least some materials in the product channels.
