PASTEURIZER FOR ESL MILK (ultra pasteurized milk)
Ultra pasteurization is an important step in the milk processing to kill pathogenic bacteria and reduce enzymatic activity when aiming at lengthening the milk shelf-life.
Extended shelf-life (ESL) milk has gained substantial market share in many countries.
In this context, REDA has developed special integrated processing technologies with the aim to offer high quality fresh milk for consumers while guaranteeing a longer shelf life.
REDA pasteurizer for safe, high quality and longer shelf-life milk
Ultra-pasteurized milk must be treated to reduce the microbiological count beyond normal pasteurization, filled under extreme hygienic conditions, stored and distributed in a cold chain.
The basic milk pasteurization is integrated with clarification, bactofugation, cream separation, in-line automatic standardization, deaeration and homogenization.
To produce milk with characteristics similar to traditionally pasteurized milk, but with a longer shelf life, it is necessary to use a technology which is able to remove the heat‐resistant aerobic spores, without changing the freshness, taste and nutritional composition of the incoming milk.
Line for ESL Milk
In order to produce milk with characteristics, as close as possible to those of classic “fresh pasteurized” milk, but with a longer shelf life, a heat-resistant aerobic spore removal technology is required that does not change the taste of the milk. One of the processes, proposed by REDA, consists of a super‐pasteurization treatment of the milk (at +125°/135°C), combined with the mechanical bacterial removal from the milk, when it is heated at a temperature of 60°C by means of a bactofuge.
The product treated in this way, while preserving the qualities of the pasteurized product such as freshness, taste and nutritional value, gained an advantage in comparison with the traditional pasteurized milk – a longer shelf life.
PLC Automation in milk ultra pasteurization
The ESL ultra-pasteurisation platform is controlled by a PLC that guarantees correct treatment of the product. The pasteurisation and product outlet temperatures, and any intervention by the diverter valves, are continuously recorded by the instrumentation in the command-and-control panel.
Airless milk evaporator comes as option in REDA milk processing
This device allows the removing of exceeding air and oxygen that can be in the product (micro dispersed bubbles of air) by reason of its several handlings: collection, storage, preparation, mixing, transfer, etc.). The non-condensable gases (oxygen and others off-flavours) are extracted by the vacuum pump and discharged.
During the milk or cream processing the device works as deodorizer. This allows the eliminating of unpleasant scents that can be in the milk (during the different seasons, for change of feeding of the livestock, etc.).
RE-B in ESL milk production
One of the processes, proposed by REDA, consists of a super‐pasteurization treatment of the milk (at +125°/135°C), combined with the mechanical bacterial removal from the milk, when it is heated at a temperature of 60°C by means of a bactofuge.
