ALFA LAVAL

Complete pasteuriser skid (reconditioned 2023)

Designed for 500 lph of juice with a holding time of 15 seconds

Plant includes:
- Product pump

- water pump (new)
- Two heat exchangers (regeneration heating and cooling)
- Holding tube designed for 15 seconds,
- Double divert value
- Electrical hot water heating system (enclosed tank)
- Control panel with chart recorder
- All operating values, connecting pipe worklant includes:



1. Pasteuriser flow meter
An independent flowmeter will be installed on the pasteuriser skid to allow for tuning of product flows during production. The flowmeter will use a local display to indicate flow only. There will be no connection to pasteuriser pump for automated flow control. To avoid having to open the control cabinet to access the VSD a speed controller will be located on the cabinet door to adjust flowrate.

Inclusions for the above item:

1 x Stainless steel IFM magnetic inductive flow meter
1 x speed controller
Mechanical installation
Electrical installation
1.2 Outlet temperature probe

A temperature probe will be located after the cooling heat exchanger. This temperature probe will use a local display to indicate temperature only. There will be no automatic control of temperature, a globe valve installed on the chilled water inlet line will be used to adjust chilled water flow to achieve temperature required.

Inclusions for the above item:

1 x Stainless steel IFM self-monitoring temperature probe
Mechanical installation
Electrical installation
1.3 Solid state relay temperature control

To improve temperature control of the pasteuriser a solid state relay will be used in place of the existing on/off contactor to control electrical heating element. This will give a more control over the hotwater / pasteurising temperature. The new SSR will be connected to the existing temperature controller.

Inclusions for the above item:

1 x Omron solid state relay
1 x B curve circuit breaker
Electrical installation
1.4 Hot water control valve

To further improve temperature precision a hot water control valve has been offered. The SSR will provide fine control for the hotwater and the control valve will provide precise control for the pasteurising temperature. A new temperature probe will be installed on the product heating outlet to reduce any lag time in control loop. A new temperature controller will be used to operate this secondary heating control.

Inclusions for the above item:

1 x Siemens 3 way control valve
1 x Intech temperature controller
1 x IFM temperature probe
Mechanical installation
Electrical installation
1.5 Hot water level switch

Installation of a secondary level switch in the heating tank. Existing switch will remain in place to cut out heating control if water level falls to a critical point. New level switch will be used to notify operator that more water is required in the system before the heating system shuts down.

Inclusions for the above item:

1 x IFM level switch
Mechanical installation
Electrical installation
1.6 Flow valve

To allow the pump to operate at the required flowrate a simple orifice valve will be installed in the process line prior to the heat exchanger. During processing the valve will be closed to force the product through the orifice in the valve and on CIP the valve will be opened to ensure full flow is available for efficient cleaning.

Inclusions for the above item:

1 x Alfa Laval butterfly valve
Mechanical installation
