  • Page 25: Cleaning

    Remove coarse dirt. Switch off the main switch of the machine before disassembly for cleaning. 5.1.1 Disassembly/assembly for cleaning The Meyn Vent cutter is so designed that daily cleaning can be performed without disassembly. © Meyn Food Processing Technology B.V.
  • Page 26: General Cleaning Schedule

    • During cleaning, never point the high-pressure water jet to the control panel or motor. • For proper functioning, after cleaning the moving parts of the machine should be sprayed with a vegetable oil. © Meyn Food Processing Technology B.V.
  • Page 27: High-Pressure Water Cleaning

    The pressure should not be too high, to avoid unnecessary mist, and to protect e.g. bearings. The unit kPa (kilopascal) is SI standard for pressure: 100 kPa 14,5 PSI 1 bar 3000 kPa 435 PSI 30 bar 10000 kPa 1450 PSI 100 bar Table 5.2 © Meyn Food Processing Technology B.V.
  • Page 28: Alkaline Foam Cleaning

    It is advisable not to use a combination of detergents and disinfectants ('detergent sanitizers"). This leaves the machine too dirty to be disinfected effectively. A combination of these two methods is of no use at all. © Meyn Food Processing Technology B.V.
  • Page 29: Disinfection

    • The used disinfectant should not affect the materials which it will contact. Consult your detergent supplier to know which detergents will fulfill these specific requirements and which cleaning directions to follow. Obey these instructions. Incorrect application may be dangerous. © Meyn Food Processing Technology B.V.
  • Page 30: Acid Foam Cleaning

    An incorrect application may be dangerous. It is advisable not to use spring water for the production of foam; this water may con- tain a high degree of chloride. Tap water reduces the chance of rust. © Meyn Food Processing Technology B.V.
  • Page 31: Advising Cleaning Chemicals To The Customer

    • Do not buy unknown (cheap) products. • To follow all user instructions carefully. • Meyn Food Processing Technology does not recommend to use specific cleaning chemicals, because we do not know which chemicals are available in each specific country. We can not know the (secret, complex) composition of the products.

    • H1 lubricants, are used when incidental contact with food products cannot be excluded. • H2 lubricants, are used for all other applications in a food plant. For all bearings and moving parts Meyn advises to use a multi purpose NLGI 2 H1 grease with the following characteristics; • Excellent water resistance.
