POA - Please Call 01404 892100

The Voran PA400LC flash pasteuriser is manufactured by internationally renowned Voran, suppliers of fruit processing equipment since 1925. Flash pasteurisers allow you to dramatically increase your rate of production, when compared with the in bottle (submerged) pasteurisation method, because they heat your product to a high temperature for a short length of time in a continuous flow.

The PA 400 LC flash pasteuriser is competitively priced and ideal for smaller to medium scale juice and cider producers looking to get away from the more time consuming process of pasteurising in bottle or in bag (for bag in box). It allows you to work with over four times as much product per hour as an in bottle pasteuriser, with lower labour costs. The PA400LC has the following features:

  • Pasteurisation rates up to 400 litres per hour
  • Closed high-temperature heating-circuit system enables pasteurisation temperatures of up to 86°C
  • Simple & central operation
  • Automatically regulated ball valve enables continuous operation without use of the bypass
  • Oil pasteuriser and tube heat exchanger with automatic temperature control
  • Compact footprint
  • Simple operation
  • See Features for Optional extras

The flash pasteurisation method:

The purpose of pasteurisation is to destroy organisms that will spoil the product – primarily yeasts that will cause fermentation.

Flash pasteurisers allow you to dramatically increase your rate of production, when compared with the in bottle (submerged) pasteurisation method. The apple juice is heated very quickly to a temperature of around 80°C in a heat exchanger before being bottled or bagged (bag-in-box) while hot.

In the PA400LC, the juice circulates from the juice pump through the heat exchanger to the bypass and back to the juice pump. In the pipes of the coaxial heat exchanger the heat transfer from water to juice takes place. After about 15 minutes when the set temperature of the controller is reached the product output valve opens automatically, and the the product is delivered to a hand-operated or automatic filling machine (supplied separately) where the bottles or bags (for bag in box) are filled while the product is still hot – destroying any bacteria or yeasts in the bottle or bag too.

Where there is an overfill protection fitted to the filler or buffer tank and this is triggered, the pasteuriser's burner stops immediately and the product output valve closes. The pasteuriser circulates the juice through the bypass until the overflow trigger is released.
The product output valve also closes after 40 seconds or if the juice temperature gets 1.5°C below the setpoint, and the pasteuriser recirculates the juice until the juice temperature reaches the setpoint.

Products which have been flash pasteurised have the same long shelf life as products pasteurised in the bottle (for apple juice in glass bottles this can be up to 2 years).

NB The pasteurisation temperature and shelf life range above are a guide only. We strongly recommend that you seek qualified independent advice to determine the temperature suitable for pasteurising your particular product and for advice on shelf-life. *For quality control, records should be kept of each batch pasteurised - see Optional extras under Features.
