Title: Heat exchanger for food processing
Inventor: MOTOMURA TAKAHITO
IPC: F28F19/04
Filed: 2008-01-24
Abstract: <P>PROBLEM TO BE SOLVED: To prevent food residues from being adhered to a heat exchange part surface, and to improve chemical cleaning performance of deposits.  <P>SOLUTION: In the heat exchanger for food processing, a surface side contacting food is covered by engineering plastic such as PEEK, PP, PET, PVDF, PFA, PTFE or the like. Since a surface contacting food is covered by plastic which is lower in thermal conductivity than metal, thermal conduction is reduced, thereby preventing a sharp temperature rise of the food in the heat exchange part surface, and as a result, adherence of food residues become harder even in the same heating temperature as a conventional one. Fixing of the adhered food residues is also prevented, thereby improving the cleaning performance. The engineering plastic is superior in heat resistance, and hence can be applied, without problems, at a service temperature in the heat exchanger for food processing.  <P>COPYRIGHT: (C)2008,JPO&INPIT
