Vigo flash pasteurisers

Vigo flash pasteurisers are designed and manufactured by our Engineers. Flash pasteurisers allow you to dramatically increase your rate of production, when compared with the in bottle (submerged/in-bottle) pasteurisation method, because they heat your product to a high temperature for a short length of time in a continuous flow.

Our smallest flash pasteuriser (750 litres per hour) allows you to work with seven times as much product per hour as an in bottle pasteuriser, with lower labour costs too. Vigo flash pasteurisers have the following features:

  • Available in 750 litre per hour or 2,500 litre per hour models
  • Very accurate temperature controls and divert functions that ensure a consistently good quality of end product
  • Pasteurisation temperatures up to 83°C
  • Water temperature, product pasteurisation juice temperature and product diversion temperature can be set.
  • Touch-screen control on latest model!
  • Very simple to operate & reliable
  • The computer control also records the temperature of the product, allowing you to effortlessly record and monitor the conditions of each batch
  • See Features for Optional extras

Manufactured, installed & commissioned by our Engineers.

Ideal for use with the CIP (Clean in Place) Tank System 220 Litre, the Vigo 8 head Inline Gravity Filler, CIMEC Automatic Bottle Filling Lines, and Semi Automatic / Automatic Bag in Box Fillers - see the Bag in Box Fillers Category in Catalogue.

Please call us on 01404 892100 to discuss your pasteurisation requirements.

We've supplied many flash pasteurisers over the years. A small sample of which are featured in our customer Case Studies.

 

See the Pateurisers category in Catalogue for our full range of pasteurisers.

Application

The flash pasteurisation method:
 

  1. The purpose of pasteurisation is to destroy organisms that will spoil the product – primarily yeasts that will cause fermentation.
  2. Flash pasteurisers allow you to dramatically increase your rate of production, when compared with the in bottle pasteurisation method.
  3. 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.
  4. Cold product is drawn from a holding vessel into the Vigo flash pasteuriser by the product supply pump and delivered to the product balance tank.
  5. The hot water system is a pressurised closed circuit. Water is heated in the boiler and circulated through the heat exchanger and associated pipelines by a pump.
  6. The product is drawn from the balance tank by a second product pump and passes through the heat exchanger where the heat transfer from water to juice takes place.
  7. A valve diverts product that has reached the desired temperature to the hand operated or automatic filling machine (supplied separately) where 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.
  8. If the product leaving the pasteuriser has not reached the desired temperature or the filler tank is full it is diverted back to the balance tank.

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 - the Vigo flash pasteuriser includes computer control which allows you to do this.
