Pipe heat exchanger, dual deflection flanged bend, adapter, system and method for transferring heat

Abstract

The present invention relates to a pipe heat exchanger (2) for heat exchange between at least two food flows (26; 30), a dual deflection flanged bend (16) for the pipe heat exchanger, an adapter (56)and a system for the pipe heat exchanger. Furthermore, described is a method for transferring heat between at least two food flows (26, 30). The dual deflection flanged bend (16) includes two separated flow paths (32, 34), wherein a first food flow (26) may be transferred in the first flow path (32) of the dual deflection flanged bend (16); and the second food flow (30) may be transferred in the second flow path (34) of the dual deflection flanged bend (16). In addition, the heat may be transferred between the two flow paths (32, 34) of the dual deflection flanged bend (16).

Description

technical field [0001] The invention relates to a tubular heat transfer device for heat transfer between at least two food streams according to the preamble of claim 1, a tube heat transfer device for heat transfer between at least two food streams according to claim 6 A double return elbow of a tubular heat transfer device, a connector for a tubular heat transfer device for heat transfer between at least two food streams according to claim 13, a connector for heat transfer between at least two food streams according to claim 18 A system for heat transfer between at least two food streams, and a method for heat transfer between at least two food streams according to claim 21. Background technique [0002] In the food industry it is often necessary to remove heat from or supply heat to liquid food. For this purpose, for example, plate or tube heat transfer devices are often used. Parallel to the use of tubular heat transfer devices, heating or cooling media, or heat accumul...

AI Technical Summary

Problems solved by technology

This is a disadvantage as the separate flow handling limits the heat transfer to the inner space of the casing

[0010] Further, the return elbow proposed in DE 696 12 998 T2 exhibits this disadvantage: temperature variations caused by the operating temperature lead to thermal expansion of the heat transfer tubes, which in turn leads to material stresses

These material stresses may eventually lead to a shortened service life due to material fatigue or increased susceptibility to stress corrosion cracking

[0011] In addition, it is unfavorable rheologically, if the food flow as it passes through the circuit bend impinges on the cover plate of the heat transfer tube with a planar surface configuration
